requirements.
(l) The insurer or reinsurer must be listed in the Federal Register as holding certificates of authority

qualified and been accepted by City
(o) This Agreement may not be operative, nor will any payments be due or paid, until approval of

from an officer of the surety company to the effect that the agent who signs the bond form for the surety
is currently in good standing with the surety.
(r) In the event a facsimile Power of Attorney is used, the facsimile must be a true copy of the
original Power of Attorney on file among the records of the surety in its home office, not be amended
or abridged, still be in full force and effect, and that City will be notified in the event of cancellation of
the particular agent.

company in the event of a default by Contractor that results in the bonding company commencing
performance of the Services shall be subject to City's approval, which approval shall not be

DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
consumers, Unadjusted 12 months ended February, Item: All items) and
15% on the Gulf Coast Diesel Fuel price index (cents per gallon), released
annually by the United States Department of Energy (DOE).
Example: Assume that the CPI for 2019 is 105.5 and for 2018 is 110.5.
Assume that the Diesel Fuel price index by the DOE for Diesel Fuel (cents
per Gallon), U.S. in 2019 is 308.5 and change from a year ago was –21.5.
The calculation is as follows: (110.5 −105.5)105.5 𝑥𝑥 .85 =4.03%
then 308.5 −(308.5 −(−21.5))(308.5 −(−21.5))𝑥𝑥 .15 =−0.98%
then
4.03% + -0.98% = 3.05% annual rate adjustment
Recycling Processing PSA
The rate adjustment index shall be based on 100% on the most recent
February CPI for the Houston-Galveston-Brazoria MSA (All Urban
consumers, Unadjusted 12 months ended February, Item: All items).

1.4. Landfill Scope of Work
This section provides an overview of the City’s specifications for Landfill services and
the Contractor’s Responsibility.
Contractor Responsibility –
Services Generally
The Contractor shall provide at its expense all labor, supervision, materials,
supplies and equipment to push, pack, cover and maintain waste at the
Landfill in accordance with the Site Operating Plan, permit and regulatory
requirements including, but not limited to, the following services:
a. Push, pack and cover all waste that has been pre-screened and
accepted by the City at the City’s scale house in accordance with the
Site Operating Plan (Exhibit 1).
b. Contractor’s Representative(s) shall be on-site at any time the facility is
accepting waste and provide and maintain an on-site communications
system to ensure communications between the scale operator, Landfill
operator, and employees during daily operations.
c. Bury waste at the Landfill with a minimum compaction rate of 1,200
pounds per cubic yard as determined through landfill surveys conducted
by the City or its designated survey contractor assuming Municipal
Wastewater Treatment Sludge is disposed at the Landfill. In the case that
Municipal Wastewater Treatment Sludge is not disposed at the Landfill, the
contractor shall bury waste with a minimum compaction rate of 1,100
pounds per cubic yard.
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
i. The City will provide the Contractor a bonus for attaining compaction
rates within the ranges described in Table 9 provided on a lump sum
basis at a minimum of once per year but no more than on a quarterly
basis. The Contractor will be eligible for this bonus at the City’s discretion
if they are in compliance with all terms of the Contract and have not
received any administrative charges within the previous six months of
operating. The purpose of the bonus is to incentivize the Contractor to
increase the compaction rate of waste to realize a cost savings for the
City by delaying the need for development of new cells and extending
the life of the landfill. The bonus will follow the rate structure as provided
in Table 9, where bonuses are calculated based on a percentage of
the Contractor’s per-ton base rate and then multiplied by the amount
of tons buried during the survey period. The bonus rate structure has
been determined based on half of the estimated annual savings that
the City would realize with compaction rates within each range. The sets
of ranges represent the incentive rate schedule for the contractor both
if Municipal Wastewater Treatment Sludge is disposed at the Landfill and
if it is diverted.
Table 9 – Compaction Rate Bonus Schedule (pounds per cubic yard)
Range (Municipal
Wastewater
Treatment Sludge
disposed)
Range (Municipal
Wastewater
Treatment Sludge
diverted)
Bonus
1,400 – 1,499 1,300-1,399 1.5%
1,500 – 1,599 1,400 – 1,499 2.0%
1,600 + 1,500 + 2.5%
Note that to achieve this the higher rates of compaction, the
Contractor will likely need to utilize ADC as described in Section 4.4.A.5.
d. Meet all requirements for daily operations and inspections under the Site
Operating Plan, including supervision and placement of waste delivered
by all haulers to the Landfill and maintenance of roads traveled by
Contractor within the Landfill site. The City has responsibility for

1. Introduction
The City of Corpus Christi's Cefe F. Valenzuela Landfill (Facility), Municipal Solid Waste
Permit 2269, is located in Nueces County, 14 miles southwest of Corpus Christi's City
Hall, at the intersection of Farm to Market 2444 and County Road 20. The coordinates
and elevation are: Latitude 27° 38' 12" N, Longitude 97° 34' 05" W, and Elevation 46.07
feet above mean sea level (MSL).
The Cefe F. Valenzuela landfill property covers 2,273.59 acres. The layout will include
the construction of two Type I municipal solid waste landfill units, which combined
measure approximately 810 acres.
This Site Operating Plan (SOP) is a modification to the currently approved permit 2269,
and is designed to bring the SOP into conformance with rule changes that became
effective in March 2006 by the Texas Commission on Environmental Quality (TCEQ).
The landfill is owned by the City of Corpus Christi (City). The City is responsible for day-
to-day landfill operations using both contract operators and City personnel,
This Site Operating Plan (SOP) is intended to provide guidance from the design
engineer to the site management and operati ng personnel. It will facilitate site
operations in compliance with applicable TCEQ regulations and current standards of
practice in the industry, compatible with the design of the facility. This Plan will serve as
a reference source and is to be used as a training tool for landfill personnel. The
contents of this SOP are consistent with the current permit and its supporting
documents, except for portions which revisions are necessary to comply with the current
SOP rules. The intent of this modified SOP is to provide additional detailed information
as required under Subchapter D of 30 TAC §330.
1.1. Description of On-Site Facilities
The facility includes an approximately 810 acre Type I MSW disposal area which will
be developed in several phases as described in t he Site Development Plan. Several
buildings will be located on site to serve several functions including an administrative
building, maintenance building, scale and scale house and other facilities to service
the landfill's operations.

The facility will also include infrastructure (pumps, pipes, valves, etc.) to allow
Enhanced Leachate Recirculation (ELR)—collection, storage, and reintroduction of
leachate to the waste mass, as well as injection of other allowable liquids.
2. Recordkeeping Requirements
To be compliant with the recordkeeping requirements of 30 TAC § 330.125, the City of
Corpus Christi keeps an organized library consisting of a copy of the facility permit, the
site development plan, the site operating plan, the final closure plan, the landfill gas
management plan, and any other plans required by permit along with all issued
modifications, and any temporary authorizations granted. The table below lists the filing
location of the records, areas/groups, document type, and site location of the recor ds.

3. Waste Acceptance Rates
As per the waste acceptance rate requirements of 30 TAC 330.125(h) and 330.675, the
City of Corpus Christi is required to perform quarterly reporting to the TCEQ. The waste
acceptance rate monitoring is intended to ensure that the facility's operations continue
to be adequate when waste acceptance rates increase. Whenever the annual waste
acceptance rate as established by the sum of the previous four quarterly summary
reports exceeds the annual waste acceptance rate estimated in the permit application,
and the waste increase is not due to a temporary occurrence, the City of Corpus Christi
will file an application to modify the permit within 90 days of the exceedance. Once the
0quarterly waste acceptance rates are calculated then an average annual waste
acceptance rate will be calculated. Data will be generated from actual scale data. The
average is based on quantities accepted at the landfill divided by the actual number of
operating days waste is accepted during the reporting period.
If an exceedance of the annual waste acceptance rate occurs, the following provision s
of the SOP will be evaluated and modified as necessary.
Number of operating personnel
Number and types of equipment
Waste compaction procedures
Odor prevention plan and control
Unloading of waste procedures
Waste screening procedures
Control of windblown waste and litter
Soil management, placement, and compaction of daily, intermediate and final
cover
Other SOP provisions, as necessary

Proceed to attempt to contain or extinguish the fire only if it appears that the
fire can be safely extinguished with available firefighting devices and
personnel.
Do not attempt to fight a fire alone; always wait for back up personnel to
arrive.
Do not attempt to fight a fire without adequate personal protective equipment.
Upon the arrival of the Fire Department, direct Fire Fighting personnel to the
fire and inform them of the actions taken.
8.4. Specific Fire Fighting Actions
If a fire occurs on a vehicle or piece of equipment, then the first step is to
bring the vehicle to a safe stop and isolate it. If the situation allows, the
vehicle must be parked away from any fuel sources, uncovered solid wastes,
personnel and vehicles. Shut off the engine, engage the brake, or use some
other appropriate method to prevent subsequent movement of the vehicle.
If the fire is in the "working face" the burning area should be isolated and
contained. Soils should be directly placed on the fire to prevent additional
oxygen from feeding the combustion. If this is not possible or is unsafe, then
attempt to cover the work face with additional soils, alternate fire mitigation
materials or water spray.
A common firefighting method at landfills includes covering the area in question
with a significant amount of soil so as to prevent any more oxygen from feeding
the combustion. Also, water could be sprayed from the water truck to help
extinguish the fire or prevent it from spreading. If a fire is detected early enough,
then a small fire may be fought with a hand held extinguisher. Fire extinguishers
will be located at the Gatehouse and on each piece of operating equipment.
Stockpiling Fire-Fighting Materials 8.4.1.
Generally, the fire-fighting technique that can be quickly employed to fight a
landfill fire is smothering with soil. The faster stockpiled soil can be placed over
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A

the fire, the more effective this method will be in controlling and extinguishing the
fire. Enough cover soil will be stockpiled within 2,300 feet of the working face as
an aid to fighting fires. A typical fire control stockpile is made up of one day's
worth of daily cover material. Based on the maximum working face size of 150'
by 150', a total of approximately 417 cubic yards of soil will be available within
2,300 feet. This amount of soil will vary depending on the quantities of waste
accepted at the site. Only one area of the landfill will typically be open at any
given time. During wet weather conditions, a wet weather operating area will be
maintained, but the normal working area will not be open at that time. During cell
transition periods, it may be necessary to operate two areas at the same time.
This will be a short-term condition. Trained staff will be located at both areas.
Each quarter, the Landfill Manager will evaluate waste acceptance at the site,
and based on the largest quantities accepted per day, establish a stockpile
quantity for the next quarter. The calculation will be made by multiplying the
active working face area times .5 feet (cover thickness) divided by 27 cubic feet
to determine cubic yards of stockpile. The landfill water truck will als o be
available on-site for firefighting.
Sufficient equipment is available on site to provide a minimum of six inches of
soil over the working face in the event of a fire; however, this is not always
deemed to be the most appropriate method for fire control. Under most
circumstances, when the fire is limited to a small area of the site, material that is
on fire will be removed from the working face to limit the size of the fire. Once
removed, the fire can be extinguished using soil, fire extinguishers , or water from
the water truck. If the fire becomes too large for control using these methods, the
fire department will be notified immediately. Below is a calculation of the City's
ability to place six inches of material over the maximum working face of 150' x
150'.
Calculation Assumptions:
Amount of soil required = surface area (150'x150') * cover thickness (.5') = 417
cubic yards

20 cubic yards per load (average) = 20.85 loads (11 per truck)
10 miles per hour average (includes loading and unloading time ) — 880 feet /
minute
11 loads @ 2,300' * 2 way = 50,600 ft / 880 ft per minute = 57.5 minutes which is
less than the required 60 minutes.
The staff will be trained upon hire and annually in fire protection and containment
techniques and will be advised of the procedural listing in this document,
Sufficient material will be available for fire prevention and to assist in
extinguishing a fire if one should occur. The projected maximum size of the
working face will vary with throughput. The working face sizes will be limited to
the following sizes under normal site operations. The ranges represent the size
of the working face including the wet weather area.
Table 8.1: Maximum Size of Working Face & Wet Weather Area
Tons per day Maximum Square Feet of
Working Face
1 - 100 2,500
101 - 1,000 10,000
1,001 - 2,000 22,500
2,001 - 3,000 40,000
Under normal working conditions, only one area will be allowed for disposal of
municipal solid waste. During wet weather conditions, a designated wet weather
area will be used. The maximum size of the wet weather area will correspond to the
size of the normal working face. A trained employee (equipment operator or spotter)
will monitor the working face during disposal operations.
8.5. Operational Activities that Store, Process, or Dispose of Combustible
Materials
Fueling Tank Operation: The City of Corpus Christi owns a 10,000 gallon fuel tank
used for the fueling of heavy equipment vehicles servicing the landfill and
surrounding City properties.

CP&Y, Inc. 30
8.6. Fire Fighting Equipment
Facility equipment will include fire extinguishers, a water truck with powered spray
capability, earth moving equipment, and a water pump. A fire extinguisher shall be
placed at all buildings on site, on each piece of heavy equipment, and at the fueling
station. Each extinguisher shall be inspected at least annually and recharged as
necessary.
The site will have a bulldozer and earth moving equipment, either a scraper and/or
excavator and dump truck, and water pump available for firefighting purposes. The
bulldozer will be available for spreading soil over the burning waste and for
dispersing any incoming load that is on fire. The scraper or excavator and dump
truck will provide cover soils for covering burning waste and for transferring
extinguished and cooled loads for disposal. The water truck may be used for
dumping or spraying water on fires. The water pump may be used for loading water
into the water truck or for pumping water directly onto a fire.
8.7. Hot Loads
Burning waste will not be unloaded in the active area of the landfill. After the gate
attendant, equipment operator, or other site personnel have identified signs of a
possible load of burning waste or a hot load, the truck will be directed to a pre -
designated portion of the landfill away from the working face, fuel areas, and other
combustion sources. The waste will be unloaded and the water truck will water down
the waste. The bull dozer may smother the fire with soil if the water does not
sufficiently extinguish the fire. The waste will then be inspected for signs of fire or hot
spots. When the fire has been extinguished and the waste has been cooled, the
waste will then be transferred to the landfill active area and disposed.
8.8. Equipment Cleaning
Limited high pressure hot water or ste am will be used to remove combustible waste
and caked material that can cause equipment overheating and increase the threat of
fire. The cleaning will be limited to equipment used primarily on the working face and
will be accomplished in an area that was constructed in a manner that is compliant

9.1. Access from Public Road
Access to the site will be controlled at the main site entrance/exit. A site entrance
sign is prominently displayed adjacent to the main entrance, There is also a gate
located at the entrance to the facility. This gate is locked when the facility is not in
operation.
9.2. Vehicle Access
Landfill vehicles and waste vehicles will have access to the active portion of the
landfill. All visitor vehicles not related to waste hauling activities are required to sign-
in at the gatehouse and are then directed to go to the landfill office to discuss the
nature of business with the Landfill Manager. The Landfill Manager reserves the
right to accept or deny entry if they feel that the visitor’s presence or intended activity
might hinder the overall landfill performance.
9.3. All-Weather Access
The main site entrance at CR20 is paved asphalt roadway that transitions into all -
weather roads in the interior of the site. Site personne l maintain the caliche roads for
all-weather access. The entrance road to the facility from CR20 and interior access
roads within the site are all-weather roads. The all-weather road and access area
should be constructed of caliche, limestone, concrete or asphalt. A "pad" may be
constructed near the disposal area so that vehicles will have maneuverability to
dispose of the waste at the working face during wet weather. The materials used for
all-weather road construction may be salvaged and reused as the acc ess roads’
locations change across the site.
9.4. Traffic Control
The Gate Attendant will restrict site access only to authorized vehicles and will direct
the traffic to the corresponding disposal area. Most commercial waste transportation
will be weighed at the scales and then directed to the active portion of the landfill.
Most non-commercial waste transportation vehicles will be directed where to go by
the Gate Attendant or by the different signs placed on site. Site personnel, signs,

and barricades will be used to control traffic flow and to expedite safe movement of
vehicles.
9.5. Site Security and Access Control Breach
Site security measures are designed to prevent unauthorized persons from entering
the site, to prevent unauthorized disposal, to protect the facility and its equipment
from potential damage caused by trespassers, and to prevent disruption of facility
operations caused by unauthorized site entry.
If an access breach is detected and the repairs take up to 8 hours after first
discovery, then the TCEQ does not need to be notif ied of the incident. However, the
incident will be recorded in the Site Operating Record as a non-reportable incident.
If an access breach is detected and the repairs are anticipated to take more than 8
hours after first discovery, then the TCEQ must be notified of the incident.
Furthermore, the incident will be recorded in the Site Operating Record as a
reportable incident.

10. Unloading of Waste
As per the "Unloading of Waste" requirements of 30 TAC § 330.133, the City of Corpus
Christi is required to have a protocol pertaining to the unloading of wastes. The
unloading of solid waste must be confined to as small an area as practically possible,
the maximum allowable working face area will be 40,000 ft2. Trained personnel will be
available to monitor each load that is disposed of in the working f ace. 30 TAC § 330.133
gives the facility staff the authority and responsibility to reject unauthorized loads and
have unauthorized material removed from the working face. A record of unauthorized
material removed from the working face will be entered in th e Site Operating Record.
Trained personnel refers to the Landfill Manager, landfill foreman, equipment operators
and laborers with waste screening training who will monitor the incoming waste at the
working face. These personnel will be familiar with the r ules and regulations governing
the various types of waste that can or cannot be accepted into the facility, including
knowledge of 30 TAC § 330.171. The personnel will also have a basic understanding of
both industrial and hazardous waste and their transpo rtation and disposal requirements.
10.1. Management of Wastes Disposed in Unauthorized Areas
Unloading of waste in unauthorized areas is prohibited. Solid waste unloading will be
controlled to prevent disposal in locations other than those specified by site

management. Signs with directional arrows and portable traffic barricades will help
to restrict traffic to designated disposal locations. Signs will be placed along the
access roads to the current disposal area or other designated disposal areas that
may be established. Any waste deposited in an unauthorized area will be promptly
removed and disposed of at the working face. Controls will also be used to confine
the working face to a minimum width consistent with the rate of incoming waste,
while allowing for safe and efficient operation. As mentioned before, the maximum
allowable working face area will be 40,000 ft2. Normally, only one working face
should be active on any given day.
10.2. Random Load Inspections at the Working Face
Random load inspections for all unauthorized wastes at the working face will be
conducted at least once every day and they will be entered in the Site Operating
Record. The random load inspections will follow the protocol established in Section
7.2 of this SOP.
10.3. Management of Prohibited or Unauthorized Wastes and PCBs detected at the
Working Face
If a prohibited waste, hazardous waste, PCBs, or any other unauthorized waste is
discovered at the working face, then the Landfill Manager or its designee shall be
notified immediately of the unauthorized waste location and actions taken. The
prohibited waste, hazardous waste, or PCBs shall be managed according to the
provisions set in Section 7.4 of this SOP.
11. Facility Operating Hours
As per the "Facility Operating Hours" requirements specified in 30 TAC § 330.135, the
City of Corpus Christi is required to specify the operating hours when the facility may be
open to accept waste and the operating hours when materials may be transported on or
off site. The facility is authorized for waste acceptance 24 hours per day, 7 days per

Personnel from Solid Waste Code Enforcement will be responsible for issuing
violations for improperly secured loads.
Portable litter control fences will be provided, as necessary, at appropriate
locations. The litter control fences may be constructed of wire mesh screens
attached to portable frames or other appropriate anchor methods. The litter
control fences should be of sufficient height to control windblown waste and litter.
The litter control fence should be located as close as practical to the active area
to control windblown waste and litter.
At least once a day that the facility is in operation, litte r will be collected that may
have accumulated on-site near the gate house and access roads used by waste
disposal vehicles. The actions taken and volumes handled will be recorded daily
in the Site Operating Record. The City is responsible for litter control within two
miles of the site entrance in either direction on CR 20. The City will provide this
litter pickup on each day that the landfill is in operation. The collected waste will
be taken to the landfill for disposal.
The working face shall be covered at least once daily during the operational
hours using approved daily cover materials to avoid prolonged exposure of
wastes and to minimize windblown effects.
14. Easements and Buffer Zones
As per the "Easement and Buffer Zones" requirements of 30 TAC § 330.14 1, the City of
Corpus Christi is required to address the location and operations concerning easements
and buffer zones.
14.1. Easements
In accordance with 30 TAC§ 330.141, solid waste unloading will not occur within an
easement or right of way that crosses the site. No solid waste disposal will occur
within 25 feet of the centerline of any utility line or pipeline easement, unless
otherwise authorized by the TCEQ. Easements, will be clearly marked as specified
in Section 15 (relating to Landfill Markers and Benchmarks) of this SOP.

CP&Y, Inc. 38
Electrical and telephone service to the site will be provided by a combination of
overhead lines on utility poles and underground piping. Drinking water will be
provided by underground piping from an on -site water supply well. Wastewater from
the buildings will be handled by an onsite septic tank system or will be transported to
a City wastewater treatment plant by tank truck. Natural gas will not be used at the
site at this time.
Several underground pipeline easements cross the site, as identified in Part III of the
Permit Application and Site Development Plan, attachment 1 -Site Layout Plans. This
map identifies specific easement widths as well. Waste shall not be placed within 25
feet of the centerline of any underground pipeline easem ent. A copy of the Permit
Application and Site Development Plan can be found in the landfill's organized
document library.
14.2. Buffer Zones
The buffer zone is located between the permit boundary and the waste footprint. The
buffer zone for the site is composed of a 500-foot wide band of site property located
adjacent to the property boundary. No solid waste unloading, storage, disposal, or
processing operations will occur within any buffer zone or right -of-way that crosses
the site. Perimeter drainage, buffer zone planting, farming, and other non-waste
related activities may occur within the buffer zone, in accordance with the SDP. The
buffer zone and/or perimeter access roads adjacent to the waste footprint will be
maintained at a width of at least 50 feet with no obstacles to provide safe passage
for firefighting and other emergency vehicles. The Landfill Manager will make
provisions to ensure that proper lighting at the working face is oriented so that it
does not become a nuisance to adjacent residents. Due to long distances between
landfill and residences, it is not anticipated that physical barriers between the site
and residences will be needed. However, if additional mitigation of light or noises
becomes necessary, the Landfill Manager or its designee wi ll take appropriate
measures to promptly address the issue. All buffer zones will be clearly marked with
a yellow marker.

15. Landfill Markers and Benchmark
As per the "Landfill Markers and Benchmark" requirements specified in 30 TAC §
330.143, the City of Corpus Christi is required to indicate how the landfill markers and
benchmarks will be maintained.
15.1. Landfill Markers
Landfill markers will be installed to clearly mark significant features. The markers will
be steel, wooden, plastic or other appropriate materials of construction. The markers
will not be obscured by vegetation and will be placed in sufficient numbers to clearly
show the required boundaries. Markers that are removed or destroyed will be
replaced within 15 days after first discovery. Guidelines fo r types, placements, and
color-coding of markers are outlined below.
Site Boundary: Site Boundary markers will be painted black. The markers will
be placed at each corner of the site and along each boundary line at intervals
no greater than 300 feet. Fencing may be placed within these markers as
required. In areas where the fence is located on the property boundary the
fence posts may be painted black and used as site boundary markers. In this
case, the post may be no less than 6 feet in height
Buffer Zone: Buffer zone markers will be painted yellow. The markers will be
placed in sequence with development of the site (see Part II of the Permit
Application and Site Development Plan, Attachment 1) along the buffer zone
boundary, at corners, and between corners at intervals of approximately 300
feet. The buffer zones will be a minimum of 500 feet wide. A copy of the Permit
Application and Site Development Plan can be found in the landfill's organized
document library.
Easements and Right-of-Way: Easements and rights-of-ways markers will be
painted green. The markers will be placed in sequence with development of the
site (see Part III of the Permit Application and Site Development, Attachment 1)
and only within the areas of solid waste activities. Markers south of grid line
N8000 will be placed as follows: At site opening (see Figure 1.13 located in

with the site boundary. The Hanlon-Buchanan Pipeline easement and right-of-
way will be marked at its intersection with the site entrance road, but not further
marked north of that intersection until site development eliminates agricultural
production north and east of this intersection (see Figure 1.16 located on Part
III of the Permit Application and Site Development, Attachment 1). at that time
the Hanlon-Buchanan pipeline easement and right-of-way will be marked at
300-foot intervals from the entrance road to gridline N8000.
Easements and rights-of-way located north of grid line N8000 will be marked at
the site opening only where they cross the entrance road and at their
intersections with the site boundary. Internal markers north of grid line N8000
will not be utilized so as to not otherwise interfere with agricultural activities.
Disposal of solid wastes north of grid line N8000 cannot occur under this
permit. Future development of areas north of gridline N8000, sh ould it be
desired, will comply with applicable solid waste regulations in effect at the time
of the desired new development. A copy of the Permit Application and Site
Development Plan can be found in the landfill's organized document library.
Landfill Grid System: Grid markers will be painted white. The grid system will
consist of lettered markers along two opposite sides and numbered markers
along the other two sides. These markers will be spaced no greater than 100
feet apart measured along perpendicular lines. Intermediate markers will be
installed in the case where markers cannot be seen from opposite boundaries.
The grid markers will be maintained during the active life of the site and
throughout the post-closure period. The grid system will mark at least the area
that will be filled with solid waste within the next three years.

SLER or GLER Area: SLER or GLER markers will be painted red. The
markers will be placed so that all areas for which a SLER or GLER has been
submitted and approved by the TCEQ are readily determinable. Such markers
are to provide site workers immediate knowledge of the extent of the approved
disposal areas. The location of these markers will be tied into the landfill grid
system and will be reported on each SLER or GLER submitte d. SLER or GLER
markers will not be placed inside the evaluated areas.
Flood Plain: There are no areas of this site inundated by the 100-year flood
plain. Therefore, such markers are not necessary.
Class 1 Areas: Specific areas dedicated to the burial of Class 1 non-hazardous
industrial solid wastes will be marked at all corners of the approved composite
liner for the Class 1 area. Such markers will provide site workers immediate
knowledge of the extent of the approved disposal areas. Markers will be located
so that they are not destroyed during operations.
15.2. Landfill Benchmarks
As required by 30 TAC § 330.143(b)(8), a permanent benchmark will be established
onsite in areas that are accessible and will not be used for disposal. The benchmark
will be a bronze survey pin set in concrete on monitor well pads. The benchmark
elevation has been surveyed from a known United States Geological Survey (USGS)
benchmark or other reliable benchmark.
16. Materials Along the Route to the Site
As per the "Materials Along the Route to the Site" requirements specified in 30 TAC §
330.145, the City of Corpus Christi is required to take steps to encourage waste
disposal vehicles to carry their load in enclosed containers or provide a tarpaulin, net, or
other means to properly secure the load. A sign will be posted stating this policy at the
CR20 entrance and at the gate house. These steps are necessary to prevent the
escape of any part of the load by blowing or spilling. The landfill personnel will be
responsible for the cleanup of waste material spilled along and within the right-of-way of
all public access roads serving the site for a distance of 2 miles in either direction from

actions taken and volumes handled will be recorded in the Site Operating Record.
17. Disposal of Large Items
As per the "Disposal of Large Items" requirements specified in 30 TAC § 330.147, the
City of Corpus Christi is required to manage large items in such a way that they do not
present an interference to site operations and/or to avoid any potential environmental
issue that might impact the site and/or its surroundings.
Refrigerators, freezers, air conditioning units, or other items containing CFC refrigerant
will not be accepted for disposal at the working face unless the CFCs contained in the
item have been removed completely by a licensed contractor in accordance with 40
CFR § 82.156(f), as amended. The City of Corpus Christi will hire a licensed contractor
to remove the CFCs contained in the items prior to disposal at the working face. The
City of Corpus Christi will temporarily store items containing CFCs in the "Appliance
Area" located inside the landfill. The Appliance Area is sufficiently large to temporarily
store large items awaiting CFC extraction. The Appliance Area will be separated from
the working face by more than 500 feet to avoid any possible interference with disposal
operations and/or to avoid any potential environmental issue that might impact the site
and/or its surroundings.
17.1. Items classified as Large, Heavy or Bulky Items (White Goods)
The following list gives examples of items that are considered large, heavy, or bulky.
Refrigerators of various sizes
Air conditioners of various sizes

Large items will be placed in the designated Appliance Area and recycled when
possible. Large items including appliances will be removed at least monthly to
eliminate the potential from these materials from becoming a nuisance. Tires that
are delivered comingled with other waste and that are removed from the working
face will be stored at the white goods area and recycled. Whole used or scrap tires
will not be knowingly disposed. Scrap tires will be removed from this area every two
weeks. Tires and appliances will be managed in a manner to reduce and eliminate
possible ponding of water to eliminate potential conditions that would promote
disease vectors.
If disposed, they will be reduced in size at the working face to the extent practical.
Large and bulky items, including brush will be disposed near the bottom of the fill
face. Items that can be classified as large, heavy, or bulky can include, but are not
limited to, white goods (household appliances), air conditioner units, metal tanks,
large metal pieces, large pieces of brush and automobiles. Special care will be taken
to achieve the maximum practical compaction of these items prior to placement of
the next layer of waste in the lift. Special care will be taken while disposing these
materials so that the liner is not damaged while this material is disposed. These
materials will not be placed within the first five feet above the liner or sidewalls.
17.2. Management of Items Containing CFCs
The respective license and certifications for the contractor will be kept on file at the
landfill office. The contractor will remove all CFCs from the site upon extraction. The
Landfill Manager will work to keep the storage of appliances on site to a minimum
number of days, never to exceed more than one month.
18. Air Criteria
As per the "Air Criteria" requirements specified in 30 TAC § 330.149, the City of Corpus
Christi is subject to TCEQ rules concerning burning and air pollution control, this
includes nuisance odors, outdoor burning, visible emissions, and particulate matter
control requirements.

Sources of Odor
Potential odor sources associated with. a municipal solid waste landfill facility may
include the wastes being delivered to the landfill, the open working face, the leachate
collection system, leachate storage ponds or tanks, ponded water, and landfill gas.
Many of the wastes received at a landfill are a source of odor upon receipt, such as
sludges and dead animals. Other wastes have the potential for becoming sources as
they biodegrade during the decomposition process. Leachate„ liquid that has passed
through or emerged from solid waste, may also be a source of odor if not properly
handled or managed in a timely manner. Ponded water and landfill gas could become a
source of odor as well. Due to the landfill being in a remote area with few neighbors,
problems associated with odors will be minimal.
18.1. Odor Management Plan
The odor management plan addresses the handling of particular odorous waste at
the landfill. Odor control measures may include, but are not limited to the following
items:
Control of any ponded. water at the site to avoid its becoming an odor nuisance
Incoming waste should be promptly landfilled.
To avoid spillage and to minimize exposure to the atmosphere, removal of
leachate should be done under appropriate weather conditions (i.e. low wind
speeds, no rain).
Regular inspections and repairs of the gasket, cap, and leachate riser backfill
material.
Use of vapor-tight gaskets on all leachate sumps.
Adding leachate collection systems to the gas management system.
Daily visits on days that the landfill is in operation will be made to the le achate
storage ponds or tanks to determine any odor problems. In the event of odor
problems, the storage facilities will be examined and appropriate measures will
be employed to minimize the odors. We do not anticipate any issues arising

from odor. The wind is predominantly from the southeast and the nearest
neighbor is approximately 1.5 miles from the ponds. If the wind is from the
north, there are no neighbors within two miles of the south property line. The
areas adjacent to the ponds are agricultural and no development is anticipated.
However, if odor becomes an issue (complaint from a nearby neighbor
specifically regarding odor from the ponds), then the City shall interview the
neighbor and determine the cause of the odor. If it is determined that the odor
is from the ponds and is a nuisance, then proper measures shall be taken as
appropriate in accordance with current design standards. Such measures may
include, but are not limited to, the use of aerators, bubblers, and as a last resort
removing the leachate and transporting it off-site for treatment.
In the event objectionable odors occur, appropriate measures should be taken
to alleviate the condition.
Identify known sources of odorous wastes and specify a time of day for these
wastes to be received so that they can be given special attention.
If odors are a result of improper use of alternate daily cover material, the cover
material will need to be re-evaluated.
Spills of odorous material should be promptly managed.
Damage or erosion of daily, alternate or FML cover should be promptly
repaired
NOTE: The City of Corpus Christi (Nueces County in general) is not in a State
Implementation Plan (SIP) designated jurisdiction; therefore SIP criteria does not
apply.
18.2. Open Burning
Open burning is banned at the landfill, unless specifically authorized by the TCEQ to
manage emergency situations, such as burning of brush when an emergency
situation arises, e.g. hurricanes.
19. Disease Vector Control
As per the "Disease Vector Control" criteria specified in 30 TAC § 330.151, the City of
Corpus Christi is required to control vectors such as rodents, flies, and mosquitoes at

landfills through daily site operations, which include the application of daily,
intermediate, and final cover. Landfill operators will conduct routine checks for insects or
rodents associated with the operations and will report problems to the Landfill Manager_
If necessary, a licensed professional should apply pesticides to ensure that proper
chemicals are used and are properly applied.
20. Site Access Roads
As per the "Site Access Roads" requirements of 30 TAC § 330.153, the City of Corpus
Christi is required to control and minimize mud, dust and litter from the landfill onto
public roadways The entrance to the facility from CR20 and interior access roads within
the landfill are all weather roads. These roads are provided for access to the active
disposal area. Re-grading to minimize potholes will be performed as necessary. The
following steps will be taken to control and minimize the impact of mud, dust and litter
from the facility:
20.1. Control and Minimization of Mud:
The road construction material will consist of caliche, limestone, or recycled asphalt,
which provides mud control for waste disposal vehicles prior to exitin g the site and
returning to public roadways. The entrance to the landfill will be swept at least once
per day on days when mud and associated debris are being tracked onto the public
roadway, and as necessary to control excessive amounts of mud that the da ily
maintenance crew cannot handle. Mud and associated debris will be controlled
through the use of all-weather roads, mechanical or hand sweepers, and equipment
capable of scraping mud from the roads.
20.2. Control and Minimization of Dust:
Dust at the facility will be controlled by watering the access roads as necessary to
suppress dust generation. The water source may be clean storm water (including
that storm water captured during cell construction), or applicable potable water
supply system.
20.3. Control and Minimization of Litter:
For control and minimization of windblown solid waste and litter see Section 13.

20.4. Re-grading of Site Access Roads:
The site access roads will be re-graded at the discretion of the Landfill Manager but
at least once a quarter.
21. Salvaging and Scavenging
As per the "Salvaging and Scavenging" requirements specified in 30 TAC § 330,155,
the City of Corpus Christi is required to take the necessary steps to ensure that
salvaging efforts do not interfere with sanitary disposal operations, and that scavenging
activities do not occur on site.
21.1. Salvaging Operations
Salvaging operations proceed at the Landfill as prescribed by Texas Law, i.e.
“controlled removal of waste materials for utilization, recycling, or sale.” Salvaged
materials should be considered as potential recyclable materials and may be stored
in a designated collection area. Salvaged items should be recycled often enough to
prevent an excessive accumulation of the material at the site to prevent odor or
other nuisance conditions from developing and to eliminate the risk of discharge of
pollutants. Items recovered through salvage operations will be removed from the site
at least once per month.
21.2. Scavenging Activities
Scavenging is the uncontrolled and/or unauthorized removal of materials from the
waste stream. Such activities will be prohibited at all times on site because of the
dangers they present to human health and the environment . The City of Corpus
Christi will take necessary measures to prevent scavenging activities on site.
22. Endangered Species Protection
Based on previous studies and a determination by both the Texas Parks and Wildlife
Department and the U.S. Fish and Wildlife Service, operations of the site is not likely to
impact endangered species (animal or plant). As the facility is developed site personnel
should notify the Landfill Manager if any change in this status is suspected.
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A

Previous evaluation and the findings of the Texas Historical Commission indicated that
cultural resources do not exist on site. As the facility is d eveloped, site personnel should
notify the Landfill Manager if any change in this status is suspected.
The Landfill Manager will be responsible for reporting suspected changes to the status
of endangered species or cultural resources to the Director of Sol id Waste Services,
The Director will then take appropriate action which may include notification of
authorities as appropriate, and ordering modification of activities in the area of concern.
23. Landfill Gas Control
As per the "Landfill Gas Control" requirements of 30 TAC § 330.159, the City of Corpus
Christi is required to control and monitor landfill gas in accordance with the "Gas
Management Plan" included in Part HI of the Permit Application and Site Development
Plan, Attachment 14. The Permit Application and Site Development Plan can be found
in the landfill's document library as per the "Recordkeeping Requirements" specified in
30 TAC § 330A25. The landfill gas monitoring results will be kept in the facility's
operating record and submitted to the TCEQ in accordance with the Site Development
Plan, Attachment 14.
23.1. Perimeter Monitoring
Perimeter Monitoring Network 23.1.1.
The LFG monitoring probe network will include LFG monitoring probes and utility
trench vents. The LFG monitoring probes will be located along the permit boundary
and north of Unit 2. The utility trench vents will be located on each utility easement
within 2,000 feet of the waste disposal areas. The probes and vents will be installed
sequentially as the development of the fill areas progress. The probes and vents will
be installed at locations when waste disposal is within 2,000 feet. Locations of the
proposed monitoring probes and vents, as well as the installation sequence plan, are
shown in Appendix 14A, Figure 14A. 1.
Permanent LEG monitoring probes of a single tube design will be used to detect the
presence of LFG in subsurface soil. The single tube probe design was chosen for
two reasons. First, it provides monitoring of the soil strata for the total depth of the

probe, minimizing the possibility of undetected LFG migration through an
unscreened zone. Second, it is difficult to achieve and maintain positive seals
between separate monitoring zones within a single well -bore, which increases the
chance for misinterpreted monitoring results.
Utility trench vents will be used to detect the presence of LFG within the utility
easements. Utility trench vents will be installed with a monitoring port for monitoring
for the presence of LPG, The vent was selected to serve as a means of monitoring
due to its ability to also be used to mitigate LFG migration within the utility
easements should it occur.
Landfill Gas Monitoring Probes and Utility Trench Vents 23.1.2.
Proposed LFG monitoring probes will be installed consistent with guidelines
presented in the TCEQ Municipal Solid Waste Division Methane Monitoring
Handbook, Version 2, December 1993. Probes will be installed to monitor the soil
strata above the higher of the lowest measured groundwater level at the monitoring
point or the lowest current or planned future elevation of waste within 1,000 feet of
the monitoring point. The probes will be screened from approximately 1.5 feet above
the bottom of the borehole to within approximately 5 feet of the ground surface.
Washed pea gravel will be placed in the borehole to app roximately 6 inches above
the screened interval and approximately 6 inches of sand will be placed over the pea
gravel. Bentonite pellets will be placed above the sand and hydrated to form an
impermeable layer to prevent air and water intrusion into the pro be boring, A
concrete pad and a steel casing extending into the borehole and above the ground
surface will also be installed. A PVC cap with a quick connect coupling will be
installed at the top of the probe for ease of monitoring. No solvents or PVC cemen t,
which may affect monitoring results, will be used during construction of the probes. A
typical detail of the proposed LFG monitoring probes is provided on Figure 14A.2 in
Appendix 14A in the SDP.
Monitoring Procedures 23.1.3.
Methane concentrations will be measured using a combustible gas indicator
calibrated against a methane standard with a sampling line for drawing samples
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A

directly to the indicator without diluting the sample. The indicator should give a direct
reading of methane concentration by volume. Equipment maintenance requirements,
monitoring procedures, and calibration information for the instruments used to
monitor methane concentrations should be kept on site with the LFG monitoring
records described in Section 3.3. Monitoring will be conducted under the oversight of
the Chief Landfill Foreman by qualified personnel or a qualified consultant. The
results will be recorded on the attached Quarterly Landfill Gas Monitoring Report
(Appendix 14B to the SDP), or similar form, and maintained in the Site Operating
Record.
If one of the tests indicate that the allowable concentration of methane has been
exceeded, verification procedures, described in Section 4 of Part III, Attachment 14
to the SDP, will be implemented. If verification procedures indicate al lowable limits
are being exceeded, notification procedures, also described in Section 4, will be
implemented.
Maintenance Procedures 23.1.4.
Each time LFG monitoring is conducted, the integrity of the LFG monitoring probes
and utility trench vents will be inspecte d by the sampler. The sampler will record
pertinent information on the Quarterly Landfill Gas Monitoring Report (Appendix 14B
to the SDP) or similar forms. The Quarterly Landfill Gas Monitoring Report will be
kept on file at the facility.
The sampler will perform the following at each monitoring event:
Verify that the LFG monitoring probe or utility trench vent number is clearly
labeled on the outer casing or lid.
Verify that the protective casing is intact and is not bent or excessively
corroded.
Verify that the concrete pad is intact (no evidence of cracking or heaving).
Verify that the padlock is functional.
Verify that the inner casing is intact.

If damage or excessive wear to the LFG monitoring probe or utility trench vent is
observed, it will be reported to the Landfill Foreman. If it is not possible to repair the
LFG monitoring probe or utility trench vent and the damage can potentially affect the
accuracy of future monitoring results, the LFG monitoring probe or utility trench vent
will be decommissioned and replaced with a new LFG monitoring probe or utility
trench vent in accordance with Sections 3.1.2 and 3.4 of the Landfill Gas
Management Plan.
The combustible gas monitoring instrument should be calibrated and maintained in
accordance with the manufacturer's instructions. The maintenance requirements for
the monitoring instrument will be available on site with the LEG monitoring records
described in Section 3.3.
23.2. Recordkeeping/Reporting
Field monitoring data records will be maintained for the methane monitoring and
kept on site as part of the Site Operating Record. Field data will be recorded on the
Quarterly Landfill Gas Monitoring Report form (or similar form) as shown in Appendix
14B of Part III.
Monitoring probes and utility trench vents will be monitored quarterly during the
following periods:
LFG Monitoring Quarters
First Quarter: January - March
Second Quarter: April - June
Third Quarter: July - September
Fourth Quarter: October - December
The LFG Monitoring Program will continue for a period of 30 years after the final
closure of the facility or until the owner or operator receives written authorization

As per the "Oil, Gas and Water Wells" requirements specified in 30 TAC § 330.161 the
City of Corpus Christi is required to identify the location of any known abandoned oil or
water wells on site.
Oil wells, gas wells, and water wells associated with support of oil and gas drilling, are
known to have been drilled on the site. During the course of site development, but prior
to beginning construction on the site, the Landfill Manager will:
a) Provide written notification to the TCEQ of the location of all known existing or
abandoned water wells, crude oil wells, natural gas wells, or other wells
associated with mineral recovery, situated within the site.
b) Provide written certification to the TCEQ, that all such aban doned wells have
been properly capped in accordance with applicable rules and regulations of the
Railroad Commission of Texas.
c) Provide a demonstration to the TCEQ that all such wells which are still in use at
the time of the notification will not conflict with the development of the site. The
demonstration will include a schedule for abandonment and plugging of wells
which are anticipated to eventually conflict with the site development. Also
included will be plans for protection of such wells, if necessary, until they are
abandoned and plugged.
24.1. Discovery of Water Wells during Facility Operation
As the site is developed, if any water wells are encountered they should be exposed,
and the casing should be cut to a minimum of 2 feet below the excavation, and th e
well should be capped and plugged in accordance with all applicable rules and
regulations of the TCEQ, the Railroad Commission of Texas, or other applicable
state agency. If water wells are located the Landfill Manager or designee must,
within 30 days, provide written notification to the TCEQ's executive director of the
location of any and all existing or abandoned water wells. Within 30 days of
discovery, the Landfill Manager will provide written certification to the Executive

25. Compaction
As per the "Compaction" requirements specified in 30 TAC § 330.163, the City of
Corpus Christi is required to compact the incoming waste to provide a more efficient use
of available space and reduce the amount of settling after the fill is complete.
Compaction will be accomplished with an ade quately sized landfill garbage
compactor(s) to minimize the volume of loose material and have more air space
available for waste disposal operations.
25.1. Compaction of Waste during Placement of Ballast
If waste is used as ballast, the Landfill Manager and/or designee will be on-site full
time during the placement of the first five (5) feet of waste over the liner system.
He/she will verify that this lower five (5) feet of waste does not contain large bulky
items that could damage the liner system or that cannot be compacted to the
required density. The Landfill Manager and/or designee will document that the waste
used for ballast has been compacted.

26. Landfill Cover
As per the "Landfill Cover" requirements specified in 30 TAC § 330.165, the City of
Corpus Christi is required to apply daily cover to control disease vectors, windblown
waste, odors, fires, and scavenging, and to promote runoff from the fill area.
26.1. Soil Management
A stockpile or borrow source for soil cover material will be maintained on -site. The
cover material will not have been previously mixed with wastes. On -site soils are
suitable for cover material as well as other soils deemed appropriate by the landfill
manager. The cover material should be managed so as to not interfere with
vehicular traffic or impede drainage. At least a portion of this cover material should
be stockpiled near the workface for potential emergency fire control.
Temporary excess soil will be stockpiled in the buffer areas, on filled areas and on
side slopes for future use on the site or for removal from the site. All stockpiles will
be maintained in conformance with the Erosion Control Plan. Stockpiles will be
oriented generally parallel to the direction of surface drainage in any given area and
will not alter drainage patterns nor block the use of the buffer areas by fire and
emergency equipment.
26.2. Daily Cover
Daily cover of waste will be applied at least once daily to control disease vectors,
windblown waste, odors, fires, scavenging, and to prevent excessive accumulation
of water within the fill. Soils and alternate daily covers that include tarps or foams, or
a combination of the three, will be utilized to complete the daily cover at the site. The
use of Saniform (or equivalent) or polyethylene tarps as an alternative daily cover
was previously approved for the Cefe F. Valenzuela Landfill. Alternate daily cover
material will not be used if the landfill will be closed more than 24 hours. Quarterly

status reports will be submitted to the TCEQ for four consecutive quarters in the
event that alternative daily cover is used.
3-M Sanifoam (or equivalent) 26.2.1.
3-M Sanifoam (or equivalent) cover will be used routinely as daily cover. 3-M
Sanifoam is an air-injected, two component synthetic foam that can be sprayed
onto the landfill solid waste surface to form an expanded protective foam blanket.
The spray thickness will be between one (1) and two (2) inches. The applied
foam "sets up" within 60 seconds to a durable solid state with consistency similar
to crushable expanded polystyrene. The foam is non -toxic and non-combustible,
and is biodegradable. The hardened foam is water insoluble which promotes
rainfall runoff, exhibits extremely low gas permeability that prevents escape of
vapors and odors, it seals the waste from flies, rodents, and other vectors, and
adheres to the waste preventing litter and dust from blowing. The foam is
mechanically crushed and broken up during subsequent landfill operations for
unimpeded movement of methane gas and leachate in the cell. Technical data
sheets and MSDS are attached for further information in Appendix IV -A.
The foam is sprayed on with a machine specially designed for this product. The
machine (Coverfoam Services, Inc., model PB-250-D, or equivalent) uses a
spray bar system to apply an even coat of foam over the solid waste. The
machine is pulled by a dozer or other tractor over the solid waste making several
adjacent passes until the surface is completely covered.
During periods of inclement weather (e.g., rain) where the foam may not set
properly, foam operations will be suspended and the working face will be covered
by the use of polyethylene tarps or soil.
Polyethylene Tarps 26.2.2.
Polyethylene tarp covers will also be used for daily cover. Typically these tarps
will be used on small working faces (less than 200' x 200') and on slopes too
steep for 3-M Sanifoam application. The tarps are fifty feet by fifty feet (50' x 50')
in size and are made out of a fire retardant woven fabric which repels water. The

taps are an effective bather against vectors, odors, and windblown litter by
effectively sealing in the waste. MSDS and physical properties for the tarp
materials are attached in Appendix IV-A.
These tarps will be installed by landfill personnel by hand at the end of the day,
Tarp installation will be such that they overlap by a minimum of one foot in such a
manner so that rainfall will run off with minimal or no infiltration. Tarps will be
weighted down with automobile tires along the perimeter and the center to
prevent the wind from blowing them off the working face. The following morning,
the tarps will be pulled off the working face by landfill personnel either by hand or
using a dozer before the start of the day's operations.
26.3. Soil
A well-compacted six (6) inch soil cover will be used to cover solid waste when ADC
materials are not used. The soil cover will be clean and not previously mixed with
waste materials. When a period of greater than 24 hours is expected to lapse before
solid waste disposal will resume at a specific working face or area, soil cover will be
used in lieu of ADC. A period of greater than 24 hours may occ ur when the site
closes on a weekend, when the working face is temporarily moved to a new area, or
other reasons.
26.4. Intermediate Cover
The top and sides of the landfill working face will be shaped to conform to landfill
operations. Intermediate cover soil will then be transported to the working face or
any area that has already received daily cover, where it will be deposited near the
upper end of the working face, spread, and compacted. Intermediate cover will
consist of soils that have not been previously m ixed with wastes and will be capable
of sustaining native plant growth.
All areas that receive waste and then become inactive for longer than 180 days will
be covered with an additional six (6) inches of compacted cover material, for a total
cover thickness of at least 12 inches. When the area is to be reused, some of this

PART IV – SOP JULY 2013
CP&Y, Inc. 57
cover material will then be removed from use as daily cover on new areas, if it can
be removed cleanly.
To minimize erosion and maintain adequate control of storm water, temporary let
down structures may be used on intermediate cover. The intermediate cover will be
seeded or sodded following its application, and vegetation and other erosion control
features will be maintained on areas that have received intermediate cover. Grading
of the intermediate cover will be undertaken in a manner to prevent ponding of
water. This is discussed in Section 27.0.
26.5. Final Cover over Class 1 Waste
Final cover construction and maintenance will be in compliance with Attachment 12 ,
relating Final Closure Plan in the Site Development Plan, and with Texas
Administrative Code Chapter 330, Subchapter K.
26.6. Final Cover
The Final Closure Plan allows for successive closure of areas of the site as they
become filled to capacity. The final cover will be maintained in a mann er consistent
with Attachment 12 of Part HI — Final Closure Plan and the requirements of Chapter
330 Subchapter K. Closure of individual areas will be in accordance with the "Sector
Fill Plan." The City will implement the plan as ongoing landfilling operat ions continue
until the time of final closure. The surface will be managed throughout the active life
of the site to minimize infiltration into the filled areas and to minimize contact with
solid waste. In general, closure of completed portions of the site will consist of the
following steps:
1. Survey controls will be implemented to control the filling of solid waste to the
lower level of the final cover.
2. A surveyed grid system or other suitable surveying measures will be used to
control placement of the final infiltration layer.
3. Testing of the various components of the final cover system will be performed
in accordance with the TCEQ regulations.

4. During the first growing season following application of final cover system, the
area will be vegetated with appropriate grasses to minimize erosion.
26.7. Cover Application Log
Throughout the active life of the landfill, a cover application log will be maintained
and made readily available for inspection. For intermediate cover and daily cover,
the log will specify the area covered, how it was placed and when it was completed.
For final cover, the log will specify the amount of cover applied over each area
(thickness) and when it was applied. The cover log will be located inside the landfill
office unless otherwise directed by the Landfill Manager.
27. Ponded Water
As per the "Ponded Water" requirements of 30 TAC § 330.167, the City of Corpus
Christi is required to prevent and control the ponding of water inside the landfill. Ponded
water can be breeding grounds for vectors, and can be a source of harborage for
vectors. Site grading and maintenance activities will be performed on an as needed
basis to help minimize the ponding of water over waste areas. Should ponded water
occur, it will be removed and depressions will be filled a s soon as practicable but no
later than seven (7) days after the occurrence. If the ponded water has come into
contact with waste, leachate, or waste contaminated soils, the ponded water will be
treated as leachate and managed in accordance with Part III o f the Permit Application
and Site Development Plan, Attachment 15 -Leachate and Contaminated Water Plan,
The Permit Application and Site Development Plan can be found in the landfill's
organized document library.
27.1. Ponded Water Prevention
The City will manage the working face of the landfill in a manner that reduces the
potential for water collecting and ponding. This will be accomplished by maintaining
the working face at sufficient grades so as to promote water running off the exposed
waste or daily cover. W ater that may pond at the working face will be removed using
landfill equipment. Water that comes in contact with waste will be treated as

CP&Y, Inc. 59
contaminated water and disposed of accordingly. Water that may pond in areas
where it does not come in contact with waste will be treated as storm water.
27.2. Routine Inspections to Identify Potential Ponding Locations
Following major storm events, the City will undertake an assessment of the site to
identify areas of potential or actual ponding. In addition, the City conducts at least
monthly reviews of the entire site to identify possible depressions as locations of
possible future ponding. City crews will be directed to these locations to re -grade
areas to reduce the potential for future ponding.
Directives to fill and re-grade potential ponding locations will be undertaken as soon
as practical after they have been identified. Ponded water that occurs in the active
portion of the landfill will be eliminated and the area in which the ponding occurred
will be filled in and regarded within seven days of detection.
During extremely wet conditions, or periods of extended storms, disposal activities
will be limited to the wet weather area. Priorities for staff during these periods are to
maintain access into and out of the site and provide disposal services as efficiently
as possible. Within 7 days of extended wet weather conditions, the City will evaluate
the site to identify areas where ponding has occurred and will take corrective actions
to reduce ponding in areas of the working face and closed areas.
27.3. Preventing Ponding of Surface Applied ELR Liquids
Landfill staff will take special care to prevent ponding of leachate and other allowable
liquids recirculated by means of surface application. Specifically, they will a pply
liquids to the surface in such a way as to ensure immediate infiltration into the waste
mass. Any surface-applied liquids that remain in puddles at the end of a day will be
pushed into the waste with a bulldozer.
27.4. Record Keeping
As a part of the overall site review, records will be maintained to identify areas where
ponding has occurred. Documentation of work completed will also be placed in the
site's file.

28. Disposal of Special Wastes
As per the "Disposal of Special Wastes" requirements specified in 30 TAC § 330.171,
the City of Corpus Christi is required to handle special wastes in a manner consistent
with TCEQ regulations.
The definition of special waste can be found in 30 TAC § 330.3, which states that
special wastes are wastes that because of their quantity, concentration, or physical,
chemical, or biological properties require special handling and disposal to protect
human health or the environment. The facility will handle special waste according to the
following guidelines.
28.1. Protocol for Disposal of Special Waste
If a generator wishes to dispose of a special waste at Cefe F. Valenzuela Landfill,
the generator must submit to the Landfill Manager a completed City of Corpus
Christi Generator's Waste Profile Sheet (GWPS) in order to provide a complete
profile for the special waste. The City of Corpus Christi will determine if the special
waste falls in the category of special wastes that do not require further disposal
authorization from TCEQ, or if the waste falls in the category of special wastes tha t
do require special disposal authorization from TCEQ.
If the special waste falls in the category of special wastes that do not require special
disposal authorization from TCEQ, then the special waste will be further evaluated
using the criteria established for special wastes. If the special waste meets all the
conditions mentioned previously, then the special waste will be considered
"acceptable for disposal."
If the special waste falls in the category of special wastes that do require special
disposal authorization from TCEQ, then the generator or its designee will be
responsible for obtaining special disposal authorization from TCEQ.
The Landfill Manager will reserve the right to accept or reject any special waste load,
even if the special waste load is deemed acceptable, if at any point he feels that the
facility could potentially experience a negative impact from the acceptance of the
special waste load.

authorization for acceptance provided that the waste is handled in accordance with
the noted provisions for each waste.
a) Special Waste from Health Care Related Facilities
Special wastes from health care related facilities which have been previously treated
in accordance with the procedures specified in 30 TAC § 330 Subchapter Y (relating
to Medical Waste Management) may be accepted.
b) Dead Animals and/or Slaughterhouse Waste
Dead animals and/or slaughterhouse waste may be accepted at without further
approval from the TCEQ provided that the carcasses and/or slaughterhouse waste
are covered by three feet of other solid waste or at least two feet of earthen material
immediately upon receipt.
c) Regulated Asbestos-Containing Materials (RACM)
RACM may be accepted at the facility in accordance with TAC § 330.171(0(3) and
as authorized in the original permit. Prior to initial receipt of RACM at this facility, the
Landfill Manager will dedicate a specific area(s) of the landfill for receipt of RACM
and notify the TCEQ in writing of the designated area(s). The Landfill Manager will
also prepare a contingency plan in case of ruptured bags and designate appropriate
personnel for implementation of the contingency plan. As the operation continues,
the Landfill Manager will notify the TCEQ in writing of any new dedicated areas for
RACM. Each load of RACM that arrives on-site will be documented. This
documentation will include the volume of mate rial, and the location and depth of its
disposal. RACM disposal locations will be identified by survey (Registered
Professional Land Surveyor) and identified on a current site drawing at the site.
Delivery of RACM will be coordinated with the Landfill Mana ger so that the waste will
arrive during times that it can be properly managed by site personnel. RACM will be

accepted at the site only if it is contained in tightly closed containers or bags, or
wrapped as necessary with 6-mil thick polyethylene.
RACM will be placed in landfill units such that it will not be exposed as a result of
erosion or weathering. When possible this will be achieved by placing the RACM
below the natural grade. At a minimum, the RACM will be placed at least 20 feet
away from exterior final sideslopes, and at least 10 feet below final grade. During
unloading and placement of RACM in the waste fill, care will be exercised to prevent
breaking open the bags or containers. One foot of soil cover or 3 -feet of asbestos-
free municipal solid waste will be placed over the RACM immediately after it is
placed in the landfill unit.
RACM that has been designated as Class I industrial solid waste, and that arrives at
the facility will be disposed of in accordance with TAC § 330.173(g)-(i) or in
accordance with this section of the Site Operating Plan.
Upon closure of the facility, a notation indicating that the site accepted RACM will be
placed in the deed record. This notation will indicate where the RACM was disposed
of on the property by showing its location on a site diagram. A copy of this
documentation will be provided to the TCEQ.
d) Non-regulated Asbestos-Containing Materials (non-RACM)
Non-regulated asbestos containing materials (non-RACM) may be accepted for
disposal provided the wastes are placed on the active working face and covered in
accordance with the requirements of 30 TAC § 330 (relating to Municipal Solid
Wastes). Under no circumstances may any material containing non -RACM be
placed on any surface or roadway which is subject to vehicular traffic or disposed of
by any other means by which the material could be crumbled into a friable state.
e) Empty Containers which have been used for Pesticides, Herbicides,
Fungicides, or Rodenticides
Empty containers which have been used for pesticide s, herbicides, fungicides, or

Disposal of Class 1 Non-Hazardous Industrial Solid Wastes will be accomplished in
accordance with the requirements of 30 TAC§ 330,173. The phrase "dedicated
trench" as used in the regulations means the specific area in which Class 1 waste is
placed for disposal.
All shipments of Class 1 waste will be accompanied by a manifest (waste -shipping
control ticket) as required by the commission. The Landfi ll Manager will sign the
manifest for any authorized shipments of Class 1 waste. The Landfill Manager will
not accept or sign for shipments of Class I waste for which the authorization to
accept has not been granted by the executive director • or has not b een authorized
by permit provisions. The landfill will retain the disposal facility copy of the manifest
for a period of three years. This time period is automatically extended if any
enforcement action involving the City or the landfill is initiated or pe nding by the
executive director.
When the landfill accepts any Class I waste, a written report of Class 1 waste
received will be submitted to the executive director. This report will be submitted no
later than the 25th day of the month following the month that the waste was
received. Reports will be submitted on forms provided by the TCEQ and will include
all the required information. Monthly reports regarding acceptance of Class 1 waste
will be submitted, including those months in which no Class 1 waste is received at
the landfill unless an exception is granted by the executive director.
While Class 1 Non-Hazardous Industrial Solid Waste will be placed only in dedicated
areas, specific dedicated areas have not been identified at this time. All permitted
disposal areas that are below the elevation of the surrounding natural grade may be
dedicated to Class 1 waste disposal. However, specific areas to be dedicated to
Class 1 waste disposal will be identified as the site is developed. When new
dedicated areas for Class 1 waste are identified, site drawings will be modified as
appropriate. Modified site drawings will be submitted to the TCEQ for review and
approval. Areas dedicated to Class I waste disposal will be constructed in
accordance with the requirements as discussed in Part III of the Permit Application

31.1. General Inspection Requirements
In accordance with §335.585 and §330.179(a)(1), the City or its operator will inspect
the landfill for compliance with the site operating plan and will develop and follow a
written schedule for inspecting monitoring equipment, safety and emergency
equipment, and operating and structural equipment (such as dikes and sump
pumps) that are important to preventing, detecting, or responding to environmental
or human health hazards. The schedule will be maintained at the landfill office and
will identify the types of problems (e.g., malfunctions or deterioration) that are to be
looked for during the inspection (e.g., inoperative sump pump, leaking fitting, or
eroding dike). This schedule will be updated to reflect the types of Class I Industrial
Waste to be accepted at the landfill.
The frequency of inspection may vary for the items on the schedule . However, the
frequency will be based on the rate of deterioration of the equipments and the
probability of an environmental or human health incident if the deterioration,
malfunction, or any operator error goes undetected between inspections. Areas
subject to spills, such as loading and unloading areas, will be inspected daily when
in use. At a minimum, the inspection schedule must include the items and
frequencies required in 40 Code of Federal Regulations §264.303 for hazardous
waste landfills.
The City or its operator will remedy any deterioration or malfunction of equipment or
structures that the inspection reveals on a schedule that ensures that the problem
does not lead to an environmental or human health hazard. Where a hazard is
imminent or has already occurred, remedial action will be taken immediately.
The City or its operator will record inspections in an inspection log or summary, and
retain these records in accordance with the requirements of §335.113(d) (relating to
Reporting of Emergency Situations by Emergency Coordinator). At a minimum,
these records will include the date and time of the inspection, the name of the
inspector, a notation of the observations made, and the date and nature of any
repairs or other remedial actions.

31.2. Personnel Training
In accordance with §335.586 and §330.179(a)(2), landfill personnel must
successfully complete a program of classroom instruction or on -the-job training that
teaches them to perform their duties in a way that ensures the facility's compliance
with the requirements of §335, Subchapter T. The City will ensure that this program
includes all the elements described in the document required under subsection
§335.586(d)(3). This program will be directed by a person trained in waste
management procedures, and will include instruction that teaches landfill personnel
waste management procedures (including contingency plan implementation)
relevant to the positions in which they are employed.
At a minimum, the training program will be designed to ensure that landf ill personnel
are able to respond effectively to emergencies by familiarizing them with emergency
procedures, emergency equipment, and emergency systems, including, where
applicable:
procedures for using, inspecting, repairing, and replacing facility emergency
and monitoring equipment;
communications or alarm systems;
response to fires or explosions;
response to ground-water contamination incidents; and
shutdown of operations.
Landfill personnel must successfully complete the program required in §335.586(a)
within six months after the date of their employment or assignment to the landfill.
Employees will not work in unsupervised positions until they have completed the
training requirements of §335.586(a). Landfill personnel must take part in an annual
review of the initial training required to ensure that ongoing training needs are
addressed and maintained. The owner or operator must maintain the following
documents and records at the facility:
The job title for each position at the facility related to waste management, and
the name of the employee filling each job;

A written job description for each position listed above. This description may
be consistent in its degree of specificity with descriptions for other similar
positions in the same company location , but must include the requisite skill,
education, or other qualifications, and duties of employees assigned to each
position;
A written description of the type and amount of both introductory and
continuing training that will be given to each person filling a position listed
above; and
Records that document that the training or job experience required has been
given to, and completed by, landfill personnel.
Training records on current landfill personnel will be kept until closure of the facility
and training records on former employees will be kept for at least three years from
the date the employee last worked at the facility. Landfill personnel training rec ords
may accompany personnel transferred within the same company.
31.3. Waste Analysis
In accordance with §335.587 and §330.179(a)(3), the following waste analysis
requirements apply to the landfill:
Before treating, storing, or disposing of any waste, the City will obtain a
chemical and physical analysis of a representative sample of the waste. At a
minimum, the analysis will contain all the information that must be known to
treat, store, or dispose of the waste in accordance with §335, Subchapter T.
o A waste generator's studies conducted on waste generated from
processes similar to that which generated the waste to be managed at
the facility may be included in the data base required.
o The City may arrange for the generator of the waste to supply the
information required by §335.587(a)(1). If the generator does not
supply the information, and the City chooses to accept a waste, City
will be responsible for obtaining the information required to comply with
the regulations.

CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL PERMIT NO.: 2269
PART IV – SOP JULY 2013
CP&Y, Inc. 71
The analysis may include data developed under §335, Subchapter R (relating
to Waste Classification), and existing published or documented data on a
waste or on such waste generated from similar processes.
The analysis must be repeated as necessary to ensure that it is accurate and
up-to-date. At a minimum, the analysis must be repeated:
o when the owner or operator is notified, or has reason to believe, that
the process or operation generating the waste has changed; and
o when the results of the inspection required in §335.587(a)(4) of this
subsection indicate that the waste received at the landfill does not
match the waste designated on the accompanying manifest or shipping
paper.
The City will inspect and, if necessary, analyze each waste received at the
landfill to determine whether it matches the identity of the waste specified on
the accompanying manifest or shipping paper.
The City will develop and follow a written waste analysis plan that describes the
procedures which the City will carry out to comply with the regulations. This plan will
be submitted to the TCEQ and will be kept at the landfill office. The plan will specify:
the parameters for which each waste will be analyzed and the rationale for
the selection of these parameters (i.e., how analysis for these parameters will
provide sufficient information on the waste's properties);
the test methods which will be used to test for these parameters; and
the sampling method that will be used to obtain a representative sample of
the waste to be analyzed. A representative sample may be obtained using
either one of the sampling methods described in Appendix I of Title 40 Code
of Federal Regulations Part 261 or an equivalent sampling method approved
by the executive director;
the frequency with which the initial analysis of the waste will be reviewed or
repeated to ensure that the analysis is accurate and up -to-date;

the waste analyses that waste generators have agreed to supply; and
where applicable, the methods that will be used to meet any additional waste
analysis requirements in §335.588 (relating to General Requirements for
Ignitable, Reactive, or Incompatible Wastes).
This plan will be developed when Class 1 wastes are proposed for disposal and will
be updated as needed to meet the specific needs of the individual Class 1 wastes.
31.4. Ignitable, Reactive, or Incompatible Wastes
In accordance with §335.588 and §330.179(a)(4), the City will take precautions to
prevent accidental ignition or reaction of wastes that are ignitable or reactive as
defined in §335.505 (relating to Class I Waste Determination). This waste will be
separated and protected from sources of ignition or reaction including, but not limited
to: open flames, smoking, cutting and welding, hot surfaces, frictional heat, sparks
(static, electrical, or mechanical), spontaneous ignition (e.g., from heat -producing
chemical reactions), and radiant heat. While ignitable or reactive waste is being
handled, the owner or operator shall confine smoking and open flame to specially
designated locations. "No Smoking" signs must be conspicuously placed wherever
there is a hazard from ignitable or reactive waste.
The landfill may dispose ignitable or reactive waste, or mix incompatible waste or
incompatible wastes and other materials, therefore requiring the landfill to take
precautions to prevent reactions which:
generate extreme heat or pressure, fire or explosions, or violent reactions;
produce uncontrolled toxic mists, fumes, dusts, or gases in sufficient
quantities to threaten human health or the environment;
produce uncontrolled flammable fumes or gases in sufficient quantities to
pose a risk of fire or explosions;
damage the structural integrity of the device or facility; or
through other like means threaten human health or the environment.

CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL PERMIT NO.: 2269
PART IV – SOP JULY 2013
CP&Y, Inc. 73
When the above-mentioned conditions apply, the City will document compliance with
§335.588(a) and (b). This documentation may be based on references to published
scientific or engineering literature, data from trial tests (e.g., bench scale or pilot
scale tests), waste analyses as specified in §335.587 (relating to Waste Analysis), or
the results of the treatment of similar wastes by similar treatment processes and
under similar operating conditions.
31.5. Contingency Plan
In accordance with §335.589 and §330.179(a)(5), the City has developed a
contingency plan for the landfill. The contingency plan is designed to minimize
hazards to human health or the environment from fires, explosio ns, or any
unplanned sudden or non-sudden release of waste or constituents of such waste to
air, soil, or surface water. The contingency plan will be submitted to the executive
director with the permit application and, after modification or approval, will become a
condition of any permit issued. The provisions of the plan will be carried out
immediately whenever there is a fire, explosion, or release of waste or constituents
of such waste that could threaten human health or the environment.
The contingency plan describes the actions landfill personnel will take to comply with
§335.589(a) and (f) in response to fires, explosions, or any unplanned sudden or
non-sudden release of waste or constituents of such waste to air, soil, or surface
water at the landfill. Also included are arrangements agreed to by local police
departments, fire departments, hospitals, contractors, and state and local
emergency response teams to coordinate emergency services. The City will
maintain a list of names, addresses, and phone nu mbers (office and home) of all
persons qualified to act as emergency coordinator, and this list must be kept up -to-
date and at the landfill.
A list of all emergency equipment will be kept at the facility (such as fire
extinguishing systems, spill control equipment, communications and alarm systems,
and decontamination equipment), where this equipment is required. This list must be
kept up-to-date. In addition, the plan must include the location and a physical
description of each item on the list, and a brief outline of its capabilities.

PART IV – SOP JULY 2013
CP&Y, Inc. 74
The plan includes an evacuation plan for landfill personnel in the event that
evacuation is necessary. This plan describes signals to be used to begin evacuation,
evacuation routes, and alternate evacuation routes in case the primary route is
blocked by releases of waste or fires.
A copy of the contingency plan and all revisions to the plan must be maintained at
the landfill and submitted to all local police departments, fire departments, hospitals,
and state and local emergency response teams that may be called upon to provide
emergency services.
The contingency plan will be reviewed and updated, if necessary, whenever:
the landfill permit is revised;
the plan fails in an emergency;
the landfill changes in its design, construction, operation, maintenance, or
other circumstances in a way that materially increases the potential for fires,
explosions, or releases of waste or constituents of such waste, or changes
the response necessary in an emergency; or
the list of emergency equipment changes.
At all times Class 1 waste is accepted for disposal, there must be at least one
employee either on the landfill property or on call (i.e., available to respond to an
emergency by reaching the facility within a short period of time) with the
responsibility for coordinating all emergency response measures. This emergency
coordinator will be thoroughly familiar with all aspects of the landfill's contingency
plan, all operations and activities at the landfill, the location of all records at the
landfill, and the landfill layout. In addition, this person will have the authority to
commit the resources needed to carry out the contingency plan.
Whenever there is an imminent or actual emergency situation, the emergency
coordinator (or his designee when the emergency coordinator is on call) will
immediately activate facility alarms or communication systems, where applicable, to
notify all facility personnel and notify appropriate state or local agencies with
designated response roles if their help is needed. Whenever there is a release, fire,

or explosion, the emergency coordinator will immediately identify the character,
exact source, amount, and areal extent of any released materials. The emergency
coordinator may do this by observation or review of facility records or manifests,
and, if necessary, by chemical analysis. Concurrently, the emergency coordinator
will assess possible hazards to human health or the environment that may result
from the release, fire, or explosion. This assessment wil l consider both direct and
indirect effects of the release, fire, or explosion (e.g., the effects of any toxic,
irritating, or asphyxiating gases that are generated, or the effects of any waste
surface water run-off from water or chemical agents used to co ntrol fire and heat-
induced explosions).
If the emergency coordinator determines that the landfill has had a release, fire, or
explosion that could threaten human health, or the environment, outside the landfill
property boundary and if the emergency coord inator's assessment indicates that
evacuation of local areas may be advisable, the emergency coordinator will
immediately notify appropriate local authorities, and must be available to help
appropriate officials decide whether local areas should be evacuated.
The emergency coordinator will immediately notify either the government official
designated as the on-scene coordinator for that geographical area, (in the applicable
regional contingency plan under 40 CFR Part 1510) or the National Response
Center (using their 24-hour toll free number 1-800-424-8802). The report will include:
name and telephone number of reporter;
name and address of facility;
time and type of incident (e.g., release, fire);
name and quantity of material(s) involved, to the extent known;
the extent of injuries, if any; and
the possible hazards to human health, or the environment, outside the facility.
During an emergency, the emergency coordinator will take all reasonable measures
necessary to ensure that fires, explosions, and releases do not occur, recur, or
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A

spread to other waste at the landfill. These measures include, where applicable,
stopping processes and operations, collecting and containing release waste, and
removing or isolating containers.
If the facility stops operations in response to a fire, explosion, or release, the
emergency coordinator shall monitor for leaks, pressure buildup, gas generation, or
ruptures in valves, pipes, or other equipment, wherever this is appropriate.
Immediately after an emergency, the emergency co ordinator will provide for treating,
storing, or disposing of recovered waste, contaminated soil or surface water, or any
other material that results from a release, fire, or explosion at the landfill. The City
will classify all recovered waste, contaminated soil or surface water, or any other
material that results from a release, fire, or explosion at the facility in accordance
with §335, Subchapter R (relating to Waste Classification) and in accordance with all
applicable requirements of §335, Subchapter A (relating to Industrial Solid Waste
and Municipal Hazardous Waste in General). The City will notify the executive
director, and other appropriate state and local authorities, that the landfill is in
compliance before operations are resumed in the affected area(s) of the landfill.
The emergency coordinator will ensure that in the affected area(s) of the landfill:
no waste that may be incompatible with the released material is treated,
stored, or disposed of until cleanup procedures are completed; and
all emergency equipment listed in the contingency plan is cleaned and fit for
its intended use before operations are resumed.
The City will note in the operating record the time, date, and details of any incident
that requires implementing the contingency plan. Within 15 days after the incident,
the City will submit a written report on the incident to the executive director. The
report must include:
name, address, and telephone number of the City's representative;
name, address, and telephone number of the landf ill;
date, time, and type of incident (e.g., fire, explosion);

name and quantity of material(s) involved;
the extent of injuries, if any;
an assessment of actual or potential hazards to human health or the
environment, where this is applicable; and
estimated quantity and disposition of recovered material that resulted from the
incident.
31.6. Operational and Design Standards
In accordance with §335.590(25) and §330.179(a)(6), hazardous waste from a
conditionally exempt small quantity generator as defined i n §335.78(a) (relating to
Special Requirements for Hazardous Waste Generated by Conditionally Exempt
Small Quantity Generators), may be accepted for disposal at the Cefe F. Valenzuela
Landfill, provided the amount of hazardous waste accepted from each cond itionally
exempt small quantity generator does not exceed 220 pounds (100 kilograms) a
calendar month, and provided the City is willing to accept the hazardous waste.
In accordance with §330.179(b), nonhazardous industrial waste may be placed
above natural grade provided that the conditions in §335.590(24)(F)(i)-(vi) of this title
are met, except as provided in §335.590(24)(F)(vii).
32. Enhanced Leachate Recirculation
The Cefe F. Valenzuela Landfill practices Enhanced Leachate Recirculation (ELR).
ELR includes recirculation of leachate and gas condensate back into the active
landfill waste mass, as well as introduction of other allowable liquids, with the goal of
elevating moisture content to more effectively manage waste in the long term.

1. ELR Introductory Items
Following the lead of several other landfills around Texas that have successfully
implemented Enhanced Leachate Recirculation (ELR), the City of Corpus Christi will
conduct ELR at its Cefe F. Valenzuela Landfill (“Landfill”). This Plan provides
information regarding the implementation of ELR at the Landfill.
1.1. ELR Defined
Many landfills in Texas recirculate leachate and/or landfill gas condensate back into
the waste mass in accordance with Texas law which allows such activity in a landfill
unit with a composite liner and leachate collection system (LCS). Specifically,
Section 177 of Chapter 330 of Title 30 of the Texas Adm inistrative Code
[30TAC330.177] allows recirculation as long as the landfill operator includes the
procedures in the Site Operating Plan (SOP). The Cefe F. Valenzuela Landfill is
among those landfills in Texas authorized to recirculate leachate into cells with
composite liner and LCS.
Several landfills in Texas have taken an additional step, gaining authorization to
inject specific additional liquids into the waste mass. This so called “Enhanced”
Leachate Recirculation or ELR seeks to elevate the moisture content (up to a limit of
40% by weight) of the MSW to accelerate anaerobic biodegradation of the material.
Studies have shown that doing so results in several short- and long-term benefits at
landfills and the surrounding communities, including
Accelerated rate of waste stabilization,
Reduced leachate storage and volume within the waste,
Improved leachate quality,
Accelerated landfill settlement prior to final closure,
Increased LFG generation rate, and
Reduced leachate treatment costs, including avoidance of transport to distant
Publicly Owned Treatment Works (POTWs).

1.2. ELR Management Plan
Safe and effective implementation of ELR at the Landfill requires well -documented
consideration of several aspects of the operations, including
Appropriate Infrastructure;
Knowledgeable Personnel;
Standard Operational Procedures;
Regular Monitoring;
Thorough Recordkeeping;
Accurate Reporting;
Safety Measures; and
Contingency Planning.
This ELR Management Plan (Plan) outlines the background, design, operation, and
monitoring programs for the ELR Landfill system at the Landfill. The plan also
describes the proposed sampling and analysis of leachate, safety procedures,
reporting requirements and operation associated with leachate management at the
Landfill, and includes a contingency plan to address system malfunctions.
1.3. Allowable ELR Liquids
ELR Landfills have successfully introduced a wide variety of liquids into the waste
mass, including leachate, gas condensate, clean storm water & groundwater,
effluents from wastewater treatment plants & grease and grit trap processing
facilities, etc. At the Cefe F. Valenzuela Landfill, the City of Corpus Christi will
recirculate and inject
Leachate from the Landfill itself;
Gas condensate from the Landfill itself;
On- site storm water;

Groundwater from the Landfill property; and
Other approved liquids.
1.4. Definitions
This ELROP uses the following meanings for words and phrases:
Field Capacity: The liquid absorptive capacity of a given material, typically
expressed as a moisture content (percent) limit. When a material reaches field
capacity, additional liquids will effectively pass through unabsorbed. At a landfill, this
adds directly to leachate production.
Subtitle D Composite Liner: A landfill cell liner system constructed in accordance
with standards set forth in Subtitle D of the Resource Conservation and Recovery
Act (RCRA), including composite liner systems, leachate collection systems, and
related accessories.
2. Generalized ELR Process
In general, ELR includes the following actions:
Install appropriate recirculation infrastructure, e.g. pumps, pipelines, permeable
beds (PBs), recirculation laterals (RLs), injection wells, etc.
Monitor incoming waste moisture content;
Collect leachate from landfill cells via the LCS;
Reintroduce leachate and/or other approved liquids (Section 1.3) into waste
mass [only over locations with an approved Subtitle D Composite Liner , see
30TAC330.331(b)];
o Combine stored leachate with clean liquids;
o Recirculate into landfill using permeable beds, recirculation laterals, and/or
vertical injection wells;
o Limit daily average recirculation to 100,000 gallons per landfill cell (annual
average). Refer to Appendix IV E-1 calculations;

APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 8
Limit liquids injection to maintain moisture content of the in-place waste at 35%
moisture by weight, plus or minus 5% to account for variations in the waste pack,
but at all times remaining below 40% moisture by weight;
Monitor leachate and gas generation rates to determine effects of recirculation
activities.
3. Preparatory Analysis and Design
Prior to implementation of ELR, qualified individuals or teams must perform thorough
analyses to ensure the landfill is prepared to handle likely changes in leachate
production & quality, head on the liner, and landfill gas production rates.
3.1. Leachate Production
Implementing ELR typically results in increased leachate production, especially if the
waste mass reaches field capacity. The Hydrologic Evaluation of Landfill
Performance (HELP) Model provides useful predictions regarding leachate
production within landfills. HELP Model calculations in Appendix 15A (in Part III,
Attachment 15) account for liquids injection associated with ELR Operations . The
results of the HELP Model runs confirm that head conditions on the liner will remain
below 30 centimeters in depth with the recirculation volumes limited to t he amount
indicated in Section 2. If leachate generation rates increase substantially, indicating
that areas of the Landfill have reached field capacity, the design of the LCS is such
that it can handle the additional flow of moisture.
3.2. Leachate Quality
Recirculating leachate through the waste mass typically improves its chemical
qualities, making it less difficult to manage in the event it must be sent to a
wastewater treatment plant (WWTP). Though studies and experience show the
likely improvements in chemical characteristics, each landfill is a unique environment
where actual changes may vary. Any unexpected changes to leachate chemistry
can be addressed through an ELR Contingency Action Plan (See Section 11—ELR
Contingency Plan).

APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 9
3.3. Head on the Liner
Higher leachate production can lead to increased hydraulic head on the liner without
expansion of the leachate collection system (LCS). Design of the LCS in cells with
ELR implemented will follow the appropriate indications in Appendix 15B (in Part III,
Attachment 15) to ensure that the LCS manages additional leachate effectively,
keeping hydraulic head on the liner under 30 cm of liquid.
3.4. Landfill Gas Production Rates
The increased moisture in the waste mass encountered due to ELR operations
typically leads to accelerated production of landfill gas. Upon installation of a landfill
gas collection system, as needed, the Landfill will conduct thorough analyses to
ensure the appropriate landfill gas collection infrastructure necessary to ensure safe
collection and handling of the landfill gas generated within the waste mass under
ELR conditions.
4. ELR Infrastructure
The ELR system is designed to reintroduce leachate and other approved liquids back
into the waste mass at a landfill by means of recirculation laterals (RLs), permeable
beds (PBs), vertical injection wells (VIW), and surface application (SA).
4.1. Existing Conditions
The City will install PBs and/or RLs within future cells as they are developed. Figure
15-E.1 shows a typical development detail of ELR cells. Subsequent cells will follow
a similar design and designation.
4.2. Recirculation Laterals (RLs)
Recirculation laterals (RLs) are perforated pipes installed within the Landfill to inject
leachate and other approved liquids back into the landfill waste. The laterals are
placed in trenches within the landfill waste pack, or imbedded in a granular material
and overlain with geotextile fabric to act as a filter . If granular material is used, it
should be larger in size than the pipe perforations. Suitable materials include gravel,
crushed glass, tire chips, shredded tires, and crushed concrete . All of these
materials are suitable for disposal in the landfill under TCEQ regulations, but pr ovide

a more uniform hydraulic conductivity when compared with mixed MSW . If tire chips
are used, they shall be 12-inch nominal or smaller in size and shall not be placed
within 2 feet of any liner or final cover installation unless steel belts are remove d.
The RL will be solid, fused, 3- to 6-inch diameter HDPE pipe located a minimum of
100 feet inside any side slopes to reduce leachate seep potential . The perforated
sections of the RLs will be constructed of 6--inch diameter perforated HDPE pipe. In
order to more evenly distribute leachate, the RL design may also have variable
perforation size, with perforation diameter increasing as the distance from the tank
and pump increases. A pair of holes will be placed at 5-foot intervals and increase
in size from the inlet end of the pipe to the terminal end to provide more equal
distribution of recirculated liquids.
Solid sections of RLs will connect the perforated piping to the Rec irculation Manifold
(Section 4.5 of this Plan). Installation of RLs may begin at an elevation within the
Landfill of approximately 20 feet above the liner elevations. The perforated section
of the RL will be centered in a rectangular trench and backfilled with recycled
shredded tires, aggregate, other granular material or MSW . Installers will shingle a
geotextile filter shingled over the top of the trench to minimize the infiltration of fines,
then cover the trench with a foot of intermediate cover. Landfill staff will ensure that
compactors not pass above RL’s until at least 5 feet of waste have been placed
above them.
Clean out risers will be furnished at the ends of the RLs and will daylight either at the
waste limits or on the sideslope. Cleanouts may also provide connection for LFG
control as a horizontal gas collector. Cleanouts can be extended as future cells
piggyback over these sideslopes.
Figure 15-E.2 provides typical RL details.
4.3. Permeable Beds (PBs)
Permeable beds (PBs) are a second type of distribution method consisting of a 0.1
to 2-foot thick layer of relatively high hydraulic conductivity material, overlain wit h a
geotextile fabric filter. PB installation occurs over the waste surface with a
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A

APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 11
perforated pipe running through the center of the PB, and then covered with a layer
of waste. Thickness of the PBs will vary dependent on the material used and the
quantity of material available at the time of placement . The PB can be made of
geocomposite, gravel, crushed glass, tire chips, shredded tires, or crushed concrete.
If tire chips are used, they shall be 12 -inch nominal or smaller in size and shall not
be placed within 2 feet of any liner or final cover installation unless steel belts are
removed. All of these materials are suitable for disposal in the landfill under TCEQ
regulations but provide a more uniform hydraulic conductivity when compared to
MSW . The PBs have much greater surface area then the RLs . Research indicates
the following advantages of PBs over RLs:
Increased volume of leachate recirculated per unit mass of waste.
Avoided construction costs due to the lack of trenching and fewer pipes
required (e.g., distance between PBs is 2-4 times greater than RLs).
Uniform liquid distribution reducing dry zones and differential settlement.
Increased landfill gas generation rate.
More efficient LFG collection.
The PBs will be approximately 350 to 450-feet long and 100-feet wide depending on
their horizontal and vertical location within each Phase. The PB designs show them
at least 100 feet from any exterior side slope.
PB installation will occur directly on the waste surface as the waste lift in these areas
attain design grade. One main 3 to 6-inch diameter, solid HDPE header will lead
from the Recirculation Manifold along the centerline of each PB at each elevation.
Each PB will have a cleanout at the landfill sideslope. The length of pipe inside the
PB will be constant-diameter perforated pipe, similar to the RLs. Like the RLs,
installers will drill two holes at each 5-foot interval.
The Landfill operator should take care to avoid compactor movement over a PB until
5-feet of waste has been placed over the constructed area.

Plans are in place for future connections to a LFG control system at both cleanouts
on each PB. Additionally, a loop of perforated HDPE pipe may be installed around
the perimeter of each PB for LFG collection.
Figure 15-E.3 provides typical PB details.
4.4. Vertical Injection Wells (VIWs)
Vertical Injection Wells (VIW s) can combine with or substitute for PBs and/or RLs to
inject ELR liquids into the waste pack. A VIW will adhere to the same design as a
vertical landfill gas collection well as detailed in Appendix III-F because any VIW will
eventually connect to a LFG control system. Additionally, existing vertical landfill
gas collection wells can serve as ELR VIW s if operational needs dictate. Figure 15-
E.2 provides typical VIW details.
4.5. Recirculation Manifolds (RMs) and Forcemains
As described in Appendix III-A (Water Pollution Control), leachate is collected and
stored in permanent and/or temporary storage tanks or pond(s). From the storage
tank(s) or pond(s), a recirculation forcemain discharges into various recirculation
manifolds (RM) within the Landfill. The RMs have valves capable of discharging to
each PB and RL line in each cell. When pipelines extend beyond the limits of the
lined area of the Landfill, they shall be double-walled pipe.
4.6. Infrastructure ID Codes
Each RL, PB, and VIW will have an identification code based on the design (RL, PB,
VIW ), cell location, elevation and location laterally. For example, the southern-most
RL installed in Phase 3 at elevation 140 ft would have the ID code “RL-3-140-1,” the
RL located immediately to the north of RL-3-140-1 would have the ID code “RL-3-
140-2,” and so on. Similarly, the southern-most PB installed in Phase 3 at elevation
180 feet would have the designation PB-3-180-1 and the PB installed immediately
north of PB-3-180-1 would have the ID code “PB-3-180-2,” and so on.

4.7. Infrastructure Inspections
Landfill staff will regularly inspect the ELR infrastructure to ensure it is working
properly. Inspections will primarily focus on detecting leaks and/or spills, but will
also check for proper functionality.
5. ELR Personnel
ELR requires well-trained Landfill staff to ensure smooth operations. Each of the
following tasks needs to be assigned as a responsibility to one person or position at the
landfill. In some cases, multiple responsibilities may be assigned to one employee.
Liquids Recirculation Management
Liquids Recirculation Operations
Liquids Recirculation Recordkeeping
Liquids Recirculation Infrastructure Inspection
Liquids Recirculation Infrastructure Maintenance
5.1. ELR Management
The Landfill Manager will ensure proper management of the ELR system. He or she
will be responsible for planning and development of the system and will assign tasks
to designees, as needed.
5.2. ELR Operation
The Landfill Manager assumes responsibility for effective operation of the ELR
system. He or she will be responsible for scheduling dosing and startup and
shutdown of the system. He or she may assign such tasks to other Landfill staff, as
needed.
5.3. ELR Recordkeeping
The Landfill Manager will be responsible for maintaining accurate records of ELR
system operations, including dose dates, liquid qualities & amounts, and
maintenance activities. He or she may assign recordkeeping duties to Landfill staff,
as needed.

5.4. ELR Inspection
The Landfill Manager will ensure the ELR system undergoes regularly scheduled
inspections. During these inspections, he or she, or a designee, will conduct
observations of the ELR infrastructure, making note of any deficiencies that could
lead to improper operation of the system. Observations of staff during everyday
landfill operations will supplement the regularly scheduled inspections. Operators
will inform the Landfill Manager, or designee, of any irregularities they notice as they
work. The Landfill Manager, or designee, will ensure any noted issues receive
appropriate attention and any necessary repairs and/or maintenance.
5.5. ELR Maintenance
The Landfill Manager will be responsible for maintenance of the ELR system . In
response to deficiencies noted during inspections, he or she will schedule and carry
out repair and/or maintenance activities, or will clearly assign these tasks to a
member of landfill staff. On occasion, repair or maintenance may require the service
of an outside vendor—this determination will be at the Landfill Manager’s discretion.
5.6. Training of ELR Personnel
The Landfill Manager will ensure that Landfill staff receive s appropriate training
regarding their interactions with the ELR system.
Topics covered in training will include:
ELR Infrastructure Basics (All Staff)
o Location & Arrangement
o Function & Operation
o Benefits & Responsibilities
Airspace Recapture

6. ELR Operational Procedures
ELR operations will occur in units called dosing events. A dosing event will consist of
pumping leachate from the storage tank(s) or pond(s) along with other approved liquids
through the recirculation pipeline(s) and manifold(s) to an RL or PB when recirculation is
scheduled for that cell. The daily average dosing event will be 100,000 gallons with an
annual maximum of 36,500,000 gallons for each Phase (Appendix IV E-1 calculations).
Landfill staff will determine recirculation volumes using flow meter readings.
6.1. Recirculation Lateral Dosing
Experience gathered during the operation and review of other recirculation projects
indicates that, to encourage optimum conditions, RLs dosing should amount 25 to 50
gallons per dosing event per foot of perforated trench, that dosing should occur in
only one trench at a time, and that trenches need rest between doses in order to
develop uniform wetting fronts. With this in mind, the following criteria govern
dosing of the RLs:
During each dosing, an RL will receive 25 to 50 gallons per foot of trench up
to a maximum of 50 gallons per dosing event per foot of trench during each
dosing event. This means that each RL will not receive more than 50 gallons
for each perforated foot within the trench independent of time unless the daily
maximum is reached.
Dosing will rotate to the next RL when the maximum volume is reached.
RLs will be rested a minimum of one day between dosing events.
Because RL lengths will vary, dosing volumes will also vary as follows:
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL
APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 16
For the shortest RLs (estimated at about 120 feet of perforated pipe),
estimates of liquid injection dosing range between 3,000 and 6,000 gallons
per event.
For the longest RLs (estimated at about 480 feet of perforated pipe),
estimates of liquid injection dosing range between 12,000 and 24,000 gallons
per event.
For RLs of intermediate lengths (x feet of perforated pipe), estimated dosing
ranges will range between 25x and 50x gallons per event.
Landfill staff will make regular observations of the pipelines’ and manifolds’ flow
meters and pumps’ hour meters during ELR system operation to ensure that RL
dosing quantities remain within the prescribed limits. Each RL will have a flow meter
that staff can use to determine the liquid volume injected during each dosing event .
The Landfill will retain records showing appropriate dosing in accordance with
Section 8—ELR Recordkeeping.
6.2. Permeable Bed Dosing
PBs will be loaded at a conservative rate of 1 to 3.5 gallons/dosing event/square
foot. Dosing, at flows varying between 35,000 and 157,500 gallons/dosing event on
average, will rotate to each PB similar to the RLs.
Landfill staff will make regular observations of the pipelines’ and manifolds’ flow
meters and pumps’ hour meters during ELR system operation to ensure that dosing
PB dosing quantities remain within the prescribed limits . Each PB will have a flow
meter that staff can use to determine the liquid volume injected during each dosing
event. The Landfill will retain records showing appropriate dosing in accordance
with Section 8—ELR Recordkeeping.
6.3. Vertical Injection Well Dosing
VIW dosing of ELR liquids may occur at any dedicated VIW . Dosing may also occur
at any landfill gas collection well such that the well is offline during dosing and the
resting period. The following criteria will govern dosing at VIWs:
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL
APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 17
VIW dosing shall utilize a permanent recirculation header pipeline connected
to the VIW or a water wagon or other temporary water delivery methods.
Dosing shall continue until well is full and refuses additional ELR liquids.
Care shall be taken when dosing to avoid overfilling as damage to the well,
well plug, or well casing may occur.
Each VIW shall be rested a minimum of one day between dosing events.
If a connection to a permanent recirculation lateral supplies the VIW ’s liquid supply,
Landfill staff will monitor the flow meter and pump hour meters on days when the
recirculation system is operated. Each VIW will have a flow meter that staff can use
to determine the liquid volume injected during each dosing event.
Should the VIW’s liquid supply originate from a temporary delivery method, such as
a water wagon, the dosing volume of the ELR liquids shall be determined based on
the known volume of the delivery tank and the number of full tanks dosed . In the
event the well refuses a complete tank, the full tank volume shall be recorded for
that dosing event.
Landfill management will decide appropriate u se of VIW’s based on operational
needs of the site.
6.4. Surface Application
Landfill staff may recirculate leachate and other allowable liquids via surface
application (SA) on the Landfill crown area or level areas (i.e . not side slopes), as
needed. The groundwater or clean surface water may be applied to the Landfill
intermediate cover or working face, depending on the method or procedure chosen .
Prior to any surface application, Landfill staff will install surface controls (e.g. soil
containment berms) to prevent runoff from the surface applied areas. During
surface applications, Landfill operators will take care to ensure no more than
100,000 gallons (Attachment IV E-1) of groundwater or clean surface water will be
land-applied per day.
Surface application methods may include:

CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL
APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 18
Direct mixture of the groundwater or clean surface water with the Landfill
waste loads in the working face.
A spray irrigation system.
Driving an irrigation or water dispensing tank truck or water wagon with a
spreader bar or liquid dispensing nozzle over the site.
Excavating trenches for direct groundwater or clean surface water deposit
with subsequent backfilling of trenches.
The surface application procedure used will be dependent on the properties of the
liquid, and the cost, maintenance and ease of use of the process.
7. ELR Monitoring
Monitoring of the Landfill is critical to determine how the Landfill responds to the ELR.
In order to safely and effectively operate an ELR landfill several conditions shall be
monitored during and after a dosing event.
7.1. Monitoring
Monitoring of the waste will include sampling the in-place waste to determine initial
moisture content and surveying the fill area to determine placement densities and
settlement data.
Waste Settlement 7.1.1.
One of the ELR process goals is to increase waste settlement rates . To
determine where settlement is occurring in the landfill, an annual survey shall be
conducted. This information will enable the landfill to place additional waste in
areas of settlement and reclaim that airspace.
Airspace Utilization Factor 7.1.2.
The calculated airspace utilization factor (AUF) is an important factor for the
evaluation of the ability to increase waste s ettlement, providing more airspace.
Landfills practicing leachate recirculation and/or ELR have experienced
improvements to their AUF ranging from 20 to 50 percent.
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL
APPENDIX IV-E ELR OPERATING PLAN JULY 2013
CP&Y, Inc. 19
AUF calculations are based upon the tonnage of waste placed in the Landfill and
the airspace consumed during a fixed period of time.
For example, top of waste topographic surveys were conducted in January 2010
and January 2011. Landfill scalehouse records show the tonnage of waste
disposed between those dates. With these data, one can compute the AUF
between January 2010 and January 2011. For each survey, the volume of waste
and cover soils between the top of waste and the top of protective layer is
determined. The difference between these two volumes is the airspace
consumed between the two survey dates. The relative density (AUF) in pounds
per cubic yard can be calculated by dividing the tons of waste landfilled between
the survey dates (converted to pounds) by the airspace consumed. This value is
not a measure of in-place waste density, but more a measure of air space
utilization efficiency.
AUF monitoring will occur at the frequency indicated in Table 7-1.
Waste Moisture Content 7.1.3.
Effective implementation of ELR requires knowledge of the moisture content of
the waste mass. The Landfill will establish moisture content of the waste through
a procedure outlined by the Environmental Protection Agency (EPA). In the
guidance document “Example Moisture Mass Balance Calculations for Bioreactor
Landfills,” [EPA-456/R-05-004, August 2005] the EPA describes appropriate
methods to determine moisture content at MSW Landfills.
The EPA publication states, “The NESHAP allows moisture content to be
determined using a variety of methods, as long as the procedures and
assumptions are documented and appropriate . A range of appropriate methods
exist. For example the landfill owner/operator can perform a simple mass
balance calculation. The calculation must take into account the waste mass,
moisture content of the incoming waste, mass of liquids added to the bioreactor
(including recirculated leachate), precipitation falling on the bioreactor surface,
and mass of water removed as leachate . The landfill can perform more complex
mass balances using models that take into account additional factors such as

surface runoff, landfill cover types that reduce the amount of precipitation
entering the waste mass, and water loss mechanisms such as
evapotranspiration. Another possible method for an established bioreactor would
include sampling the moisture content of the waste at multiple locations within
the bioreactor, and performing statistical calculations to determine the average
percent moisture. However, it is expected that in most cases, a mass balance
approach will be adequate to determine whether the moisture content is above or
below 40 percent and comprehensive sampling will not be needed.”
Method B: The Landfill will use the Advanced Set of Calculations in the EPA’s
Water Balance Method to determine the moisture content and to calculate the
appropriate quantities of leachate, gas condensate, and other liquids to add into
the waste mass. The Water Balance Method performs calculations in sequence
on a monthly time basis to estimate the average moisture content.

7.2. Liquids Monitoring
Monitoring of the liquids introduced to and generated by the Landfill will occur on a
regular schedule and the data will be used to develop a relationship between
recirculation and waste degradation.
Leachate Generation 7.2.1.
Flow meters on the leachate collection system will indicate the amount of
leachate generated in the landfill. In addition, liner leachate head readings
recorded as directed in the Leachate and Contaminated Water Plan (Attachment
15 to Part III) will confirm that hydraulic head on the liner remains under 30
centimeters.

Leachate Level on Liner 7.2.2.
The City will monitor the depth of leachate on the landfill liner (above the top of
the sump) with a pressure transducer located on each submersible pump within
the side slope risers. The regulatory point of compliance is 30-cm of leachate
head on the liner (above the top of the sump). In areas where ELR will be used,
the regulatory point of compliance is level with the top of the sump. Each pump
control panel uses a digital readout of the leachate head above the transducer .
Each panel is programmed such that the pump turns on when the head in the
sump reaches the top of the sump . The pump is programmed to turn off when
the head level drops to approximately 1-ft of head above the bottom of the sump.
The transducers provide continuous measurement of head, and the contr ol
panel(s) are equipped to provide a visual indication when the head over the liner
approaches the regulatory limit. All head levels are checked and recorded
monthly.
Precipitation 7.2.3.
The Landfill keeps records of precipitation data as part of its Storm W ater
Pollution Prevention Plan (SW3P). Staff can readily access those records, as
needed, as it relates to ELR operations.
Volume of Liquids Recirculated 7.2.4.
One goal of ELR is to increase the moisture content of the MSW to provide a
better environment for the sustenance of microbes responsible for
biodegradation of water. MSW typically enters landfills with moisture content
around 20% by weight. Corpus Christi would like MSW moisture content at the
Cefe F. Valenzuela Landfill to rise to 35% +/- 1%. Attachment IV-E-1 contains
tables showing how many gallons should be injected per incoming cubic yard of
waste (the values vary depending on assumed incoming waste density).
Immediately after, Attachment IV-E-2 presents the methodology to determine the
calculated waste moisture content due to liquids injection and environmental
conditions. Table 7-2 lists the ELR liquid characteristics that landfill staff will
monitor regularly with their respective monitoring schedules.

7.3. Landfill Gas Monitoring
An ELR landfill is designed to accelerate the rate of waste decomposition. This in
turn accelerates the rate of LFG production. If the Landfill installs a landfill gas
collection system, staff will monitor it to measure the percentage of the methane and
oxygen in the LFG and determine if the ELR process is functioning correctly.
Gas Parameters 7.3.1.
Landfill gas parameters to be monitored will be established prior to installation of
any landfill gas collection system. Typically, landfills test collected gas to
determine the content of a variety of chemical constituents . Table 7-3, provided
for reference only, shows a typical monitoring schedule for a landfill gas
collection system.

8. ELR Recordkeeping
Implementation of ELR at the Landfill will generate records of relevant operational and
monitoring characteristics. ELR Records include
Dose Liquid Quantity Records,
Recirculation System Installation Records,
Recirculation System Inspection Records, and
Other information necessary to ensure effective implementation.
ELR records will become part of the Landfill’s Site Operating Record and will remain at
the Landfill for the life of the Site.
9. ELR Reporting
Operations of ELR Landfills do not trigger any special reporting requirements. Thus, the
Landfill will simply abide by the reporting schedules already in place at the facility.
10. ELR Safety Measures
Implementing ELR will not require application of any specific safety measures beyond
those already practiced by facility staff to ensure safe operation of the Landfill . Thus,
Landfill staff will keep themselves, customers, visitors, and the environment safe
through adherence to the Landfill’s Safety Plan.
11. ELR Contingency Action Plan
Implementing Enhanced Leachate Recirculation (ELR) at a landfill can lead to some
situations that may require special remedial actions in a short amount of time. With this
in mind, the managers of the Cefe F. Valenzuela Landfill have developed an ELR
Contingency Action Plan (CAP) to address the most likely potential emergencies .
Conditions requiring activation of the CAP may turn up during routine inspections,
monitoring, maintenance, etc. Any activation of the CAP will result a staff generation of
an event report, a copy of which will go in the facility operating record.

problem(s) and/or unanticipated problem(s) will arise . In such cases, Landfill
staff will develop an event-specific action plan to remediate.
If multiple problems exist, prioritize them by severity and/or threat so as to
address them in order of seriousness;
Ensure effective security measures are in place to protect other facilities,
operations, and/or structures at the Landfill from any threat;
Identify corrective actions required to address each problem;
Establish a schedule to implement corrective actions;
Implement Remedial Actions 11.2.4.
When Landfill staff has settled upon an effective action plan, they will then initiate
remedial activities. During remediation, staff will be sure to
Contain any potential environmental contaminants for removal, disposal,
and/or treatment;
Protect other threatened structures or facilities;
Repair any earthwork damage with on -site equipment, up to the capability
of facility personnel; and
Secure assistance from specialized personnel, as needed, to complete
certain tasks (e.g. electrical work, liner repair, pump repair, etc.).
Notify Regulatory Agencies & Follow-up Internally 11.2.5.
Depending on the type and severity of the incident, provisions of Title 30 of the
Texas Administrative Code [30TAC] may require notification to the TCEQ
regarding its occurrence and the remedial actions. After remediation, Landfill
management will assess the need for notification to the TCEQ, and wi ll do so in
accordance with the appropriate sections of Texas Law.
For the sake of improved operations going forward, any incident requiring
implementation of this CAP will trigger a follow-up review of the event. The
evaluation will include

Management of Moisture Addition
This section presents an overview of moisture calculations and a straightforward
method for determining the correct amount of moisture to add to the MSW based upon
collected data. Moisture does not have to be added in a short period of time in order to
reach field capacity. Liquids can be recirculated and/or surface applied at lower
volumes at first. When liquids are reinjected in the same areas, these calculations can
be used to estimate how much moisture levels may have increased in MSW as
received. This is important throughout the life of the ELR development. As more liquids
are recirculated into each phase, settlement occurs. This affects landfill density and, as
seen in the following tables, directly affects the ability to absorb further moisture. This
means that liquid injection volumes can be lowered as each Phase matures in
degradation.
An optimum moisture level exists for each municipal solid waste landfill that will allow
the process of biological stabilization and compaction to proceed at the highest rate
possible. Existing literature suggests that the optimum moisture level is between 35 -
50%. For this project the moisture content will be maintained at or below field capacity
(less than or equal to 35%)
.
MSW Moisture Content Determination
The gravimetric procedure for determining the moisture content of MSW is relatively
simple and is based upon the methods for determining total solids as presented by
“Standard Methods for the Examination of Water and Wastewater and/or EPA Method
160.3. An initial weight is obtained for a significant field sample of MSW (sample size
between 0.5-1.0 kg) collected from the working face. The moist sample is dried at 103-
105 C to a constant weight. The percent moisture is calculated as follows:
Percent Moisture = 100 - (dry weight/wet weight * 100)
For example: A 1000-gram field sample of MSW is obtained and dried. The constant
dry weight of the sample is found to be 700 grams. The percent moisture is calculated:
Percent Moisture = 100 - (700/1000 * 100)
= 100 - (0.70 * 100)
= 100 - 70 = 30%
Moisture Addition Determination
The moisture addition tables included in this attachment should be used once the
working face percent moisture results are obtained from the laboratory. An explanation
of the preparation of the tables follows.
A simple algebraic expression was developed to demonstrate the relationship between
the total weight for each cubic yard of MSW and any given percent moisture found for
collected field samples. A typical moisture level for freshly compacted MSW is 25%.
The in-place moisture weight, X, was calculated for MSW dry weights from 800 to 2000
Pounds per cubic yard from the formula:
DocuSign Envelope ID: E0604FA4-2250-49F2-8D28-BEAEF6D492DFDocuSign Envelope ID: 1E470735-0508-40CE-93E7-05EB73B1667A
CITY OF CORPUS CHRISTI, CEFE F. VALENZUELA LANDFILL
ATTACHMENT IV E-2 ELROP MSW MOISTURE CALCULATIONS JULY 2013
CP&Y, Inc. 4
X = Decimal Fraction Moisture (Dry Weight Density + X)
For example, for a Moisture Level of MSW = 25 Percent:
Let the dry weight density equal 1000 pounds/cubic yard and the moisture equal 25%
(0.25 as decimal).
X = 0.25 (1000 + X) = 250 + 0.25X
0.75X = 250
X = 333.33 pounds
Pounds may be converted to gallons by dividing by 8.34 lbs/gal water.
So, 333.33/8.34 = 39.97gallons.
Wet weight = Dry weight + Moisture weight = 1000 + 333.33 = 1333.33 pounds/yd 3
These equations served to generate the first four columns of the tables in this
Attachment.
The equation may be checked by the formula for percent previously presented.
Percent Moisture = 100 - (dry weight/wet weight * 100)
Percent Moisture = 100 - (1000/1333.33 * 100) = 100 - 75 = 25%
Addition of Liquids to Achieve Moisture Goal
Using the same line in the table with the MSW moisture level at 25% and 1000
pounds/cubic yard dry weight, the liquid weight present at 35% moisture is calculated.
Calculation check:
X = 0.35 (1000 + X)
X = 350 + 0.35X
0.65X = 350
X = 538.46 pounds
Percent Moisture = 100 - (dry weight/wet weight * 100)
= 100 - (1000/1538.46 * 100)
= 35%
The amount of moisture to be added to MSW at 25% to achieve 35% was done by
subtraction.
Moisture to be added = 538.46 - 333.33 = 205.13 pounds or 24.60 gallons/cu yd.
The amount of liquid that is required to achieve 35 % moisture in existing MSW was
calculated similarly by determining the moisture weights for 35 % moisture and

subtracting the existing moisture weight for the various densities and moisture levels
presented.
Addition of Liquids to Achieve 35% Moisture
The estimated annual compaction rate at Cefe F. Valenzuela Landfi ll is 1175 lbs/yd3, as
reported in the Landfill’s 2012 Annual Report to the TCEQ. The following calculations
yield the amount of enhanced leachate to be recirculated to the MSW at 20% to achieve
35%.
Calculation check:
FY Cubic Yards

2011 714956
Average Annual 753,044
X = 0.20 (1175+ X)
X = 221+ 0.20X
0.80X = 221
X = 276.75 pounds/ cu yd.
X = 0.35 (1175 + X)
X = 411 + 0.35X
0.65X = 411
X = 632.69 pounds/cu yd.
To determine the weight of moisture to add, subtract the 20% moisture weight from the
35% moisture weight.
Moisture to be added : 632.69 - 276.75 = 355.94 pounds/cu yd. or 42.73 gallons/cu yd.
The average daily dosing event:
42.73 gal/cu yd. x 753,044 cu yd./yr x (1 yr/365 days) = 88,157 gal/day
Operational experience shows that daily incoming waste rates fluctuate regularly from
the average typically peakin in early summer and waning through the winter. Most
landfills will see peak daily rates about 20% above the allowable daily average. Thus,
the cap on daily liquids injection account for this fluctuation:
88,157 gal/day x 1.25 = 110,197 gal/day.
Hence, to maintain a moisture content of 35% +/- 5% in the MSW, the cap on liquids
injection is set at 100,000 gallons per day.

This Attachment IV-E-2 is an excerpt from U.S. Environmental Protection Agency
Document EPA-456/R-05-004, dated August 2005. The Landfill will apply the
appropriate methodology to show that waste moisture content remains below the
permitted limits.
2.0 WATER BALANCE METHOD
The Water Balance Method performs several calculations in sequence on a monthly
time basis to estimate the average moisture content of the waste. It was originally
designed to measure evapotranspiration from soils and was then adapted for landfill
conditions. Our suggested procedure for using the Water Balance Method involves
a two-tiered approach. Method A is a simplified equation that only incorporates
factors which most significantly affect the average moisture content of the waste
mass. The simplified equation also assumes that all precipitation falling directly on
the landfill's surface will become moisture in the waste mass. The primary factors
that are accounted for in the simplified equation are:
Incoming waste moisture,
Precipitation (only precipitation that falls directly on the landfill's surface;
assuming that all surface runoff from adjacent areas is diverted around the
landfill surface),
Liquids addition (recirculated leachate, water, etc.), and
Leachate production.
If landfill owners/operators are satisfied with the results of the Method A equation,
then no further calculations are needed. However, if further analysis is required,
then landfill owners/operators can proceed to Method B which comprises a more
advanced set of calculations. This more complex procedure takes into account the
four factors included in the simplified equation of Method A plus the following four
elements:
Moisture retained in the landfill surface or cover material,
Surface runoff,

Surface evaporation, and
Evapotranspiration.
A detailed description of each step is discussed in Sections 2.1 and 2.2,
respectively, of this attachment.
2.1 Method A: Simplified Equation
The potential moisture content of the waste mass in the bioreactor landfill can be
estimated using the following simplified equation of the Water Balance Method:
( )
Where,
PMC = estimated potential moisture content of the waste mass (% moisture content
on a wet weight basis);
Lo = moisture entering with the waste mass (kg moisture/kg total waste mass as
received);
M = total waste mass in bioreactor cell on an as received basis (kg total waste mass
as received);
P = total precipitation (kg total precipitation);
LA = total liquids added to the waste m ass, including recirculated leachate (kg total
liquids); and
LCH = total leachate collected (kg total leachate).
If the bioreactor landfill has been at steady state (i.e., no fluctuations in any of the
factors above) since the bioreactor cell or entire bi oreactor landfill opened, then M,
P, LA, and LCH can be calculated as monthly averages instead of totals. However,
this scenario is not likely to occur.
When using Equation 1, landfill owners/operators must keep records of data and
assumptions used to determine values of Lo, M, P, LA, and LCH for their bioreactor

landfill. The following bullet points provide potential guidelines for determining and
recording these values.
Lo: According to Tchobanoglous’ Integrated Solid Waste Management:
Engineering Principles and Management Issues, most MSW in the United
States has a moisture content of 15 to 40 percent, with 25% as typical.
Moisture content of MSW depends primarily on the composition of the waste,
the season of the year, and the humidity and weather conditions of the
surrounding environment. For example, the moisture content of 100
kilograms of incoming wet waste can be estimated as: [(100 kg - d)/100 kg],
where d is the total dry weight in kilograms of the solid waste components
within the 100 kilograms of wet waste received.
M: To calculate total waste mass, waste acceptance or waste placement data
is needed and should be documented accordingly.
P: Total precipitation in inches of water can be obtained from precipitation
measurements at the landfill or from nearby weather station data. Convert
the precipitation from inches to kilograms of moisture using the following
equation:
( )
( )
( )
LA: The total amount of liquids added can be estimated using measurements
currently taken at the bioreactor site for design and operational purposes. For
example, if a closed loop bioreactor with horizontal trenches uses a flow
meter to measure the amount of leachate recirculated, then flow meter
reading records can be used to estimate total leachate addition (e.g.,
converting the flow rate each month to kilograms of leachate per month and
then summing the monthly readings to obtain a total liquids added amount).
Water introduced at the surface of the landfill via truck could be measured

using a simple volume displacement calculation, such as: (gallons of water
stored per tank truck) * (number of tank trucks emptied onto landfill surface) *
(3.78 kilograms per gallon of water). The types of liquid addition methods
vary by bioreactor landfill site, therefore, the types of measurement methods
will differ as well. We recommend that each landfill owner/operator calculate
total liquids using methods most appropriate for their bioreactor design.
LCH: Similar to liquids addition, the total amount of leachate produced can be
estimated using leachate collection records generated at the landfill
bioreactor for design, operational, and possibly regulatory purposes. For
example, if a bioreactor landfill uses a flow meter to measure the amount of
leachate produced or collected, then flow meter reading records can be us ed
to estimate total leachate generation (e.g., converting the total flow rate each
month to kilograms of leachate per month and then summing the monthly
readings to obtain a total leachate amount). The leachate value used in
Equation 1 should include leachate that is recirculated as well as any excess
leachate that may be treated or disposed of by other means. We recommend
that each landfill owner/operator calculate total leachate generated using
methods most appropriate for their leachate collection sys tem design.
2.2 Method B: Advanced Set of Calculations
The following items are required inputs for Method B of the Water Balance Method
calculations:
Average monthly temperatures in degrees Fahrenheit (ºF)
Site latitude
Average monthly precipitation in inches of water
Landfill surface conditions
Soil & vegetation type for final cover (if any)

percolation of precipitation into the bioreactor landfill considering moisture contained
in the landfill surface or final cover, surface runoff, evaporation losses, and
evapotranspiration. Step 17 is very similar to Equation 1 for Method A. The only
difference between Step 17 and Equation 1 is that Step 17 replaces the amount of
precipitation with the amount of moisture that percolates into the waste mass . The
foundation for this sequence of calculations and example spreadsheet comes
directly from McBean’s Solid Waste Landfill Engineering and Design.
Sequence of Calculations for the Advanced Water Balance Method (Method B):
Steps 1 - 5: Determine potential evapotranspiration
1. Collect average monthly temperatures (T) in ºF for the area surrounding the
bioreactor landfill. Enter this information in the spreadsheet.
2. Using the monthly temperatures, determine the monthly heat index (h) for each
month. Monthly heat indices can be determined using Table A .1 in the Reference
Tables. For months where the temperature is less than 32 ºF, set h to zero. Sum
the monthly heat indices to obtain a yearly heat index (H).
3. Using the monthly temperatures and yearly heat index, find the Unadjusted
Potential Evapotranspiration (UPET) for each month using Table A.2 in the
Reference Tables.
4. Using the latitude at the bioreactor landfill site, find the monthly correction factor
for sunlight duration (r) in Table A.3 in The Reference Tables.
5. Multiply the monthly UPET by the monthly r to result in the monthly Adjusted
Potential Evapotranspiration (PET) for each month in inches of water.
Steps 6 - 9: Determine amount of precipitation that infiltrates the bioreactor
landfill
6. Enter the average monthly precipitation (P) in inches of water for the bioreactor
landfill site.

7. Enter the appropriate runoff coefficient (Cr/o) to calculate the runoff for each
month. Table A.4 in The Reference Tables can be used to determine the most
appropriate runoff coefficient based on the landfill surface conditions.
8. Multiply the monthly precipitation by the monthly runoff coefficient to obtain the
runoff (r/o) for each month in inches of water.
9. Subtract the monthly r/o from the monthly P to obtain the monthly infiltration (I) in
inches of water.
Steps 10 - 13: Calculate moisture storage in the landfill surface cover material
10. Subtract the monthly PET from the monthly I to determine the moisture available
for storage at the landfill surface (I - PET) in inches of water.
11. For negative (I - PET) values only, add the (I - PET) value for the preceding
month to the current month to calculate the Cumulative Water Loss (ACCWL).
Begin the summation with zero accumulated water loss for the last month having a
positive (I - PET) value.
12. Determine the monthly Soil Moisture Storage (ST) in inches of water for the
landfill surface by following the steps outlined below:
a. Determine the initial ST for the soil depth and type. Table A.5 can be used to
configure the initial ST (retention) value.
b. Assign the initial ST value to the months having a positive (I - PET) value,
prior to months that have a negative (I - PET) value.
c. Determine the ST for each subsequent month having a negative (I - PET)
value. Use the monthly ACCWL values and Table A.6 to obtain the ST.
d. For subsequent months having an (I - PET) value greater than or equal to
zero, add the (I - PET) value for each month to the preceding month’s ST. Be
careful not to exceed the soil field capacity (i.e., fraction of water in the soil
based on the dry weight of the soil). Enter the soil field capacity for monthly
soil moisture storage if the sum exceeds the field capacity.
13. Calculate the change in the ST, or )ST, for each month in inches of water by
subtracting the ST for the preceding month from the current month’s ST.

Steps 14 - 16: Calculate actual evapotranspiration and percolation of moisture
into the bioreactor landfill waste mass
14. Calculate the Actual Evapotranspiration (AET) by following the steps outlined
below:
a. For wet months where the (I - PET) value is greater than or equal to zero, set
the AET equal to the PET.
b. For dry months where the (I - PET) value is negative, use the following
equation for the AET: AET = PET + ((I - PET) - )ST). This equation
represents the fact that the evapotranspired amount is the amount po tentially
evapotranspired plus that available from excess infiltration that would
otherwise add to soil moisture storage plus that available from previously
stored soil moisture.
15. Calculate the monthly percolation (PERC) as follows:
a. For wet months where the (I - PET) value is greater than or equal to zero, use
the following equation for the PERC: PERC = ((I - PET) - )ST).
b. For dry months where the (I - PET) value is negative, set the PERC equal to
zero.
16. As a check for Steps 7 through 15, calculate t he average monthly precipitation
(P) in inches of water to be sure they match the original precipitation values entered
in Step 6. The precipitation calculation is as follows: P = PERC + AET + )ST + r/o.
Step 17: Estimate moisture content of the waste mass in the bioreactor landfill
17. Convert PERC from inches of moisture to kilograms of moisture per kilogram of
waste (e.g., [PERC (in) * (1 ft/12 in) * (ft2 of bioreactor landfill surface) * (1 gal/0.134
ft3) * (3.78 kg/gal water)] / (total kg wet waste mass in bioreactor)). Then, estimate
the potential moisture content of the waste mass, on a monthly wet weight basis,
using the following equation:
PMC = Lo + PERC + LA - LCH (Equation 2)

Where,
PMC = estimated potential moisture content of the waste m ass (kg moisture/kg wet
waste);
Lo = average amount of moisture in the initial waste added each month (kg
moisture/kg wet waste);
PERC = monthly percolation (kg moisture/kg wet waste);
LA = amount of liquids added to the waste each month, including recircu lated
leachate (kg liquids/kg wet waste); and
LCH = amount of leachate produced each month (kg leachate/kg wet waste).
Lo, LA, and LCH should be estimated and documented similarly to Method A
procedures described under Equation 1 in Section 2.1 of this att achment. The
difference between Equations 1 and 2 is that Lo, LA, and LCH are monthly values
per kilogram of waste in Equation 2, not total values. Therefore, for Equation 2,
monthly values will need to be determined and then divided by the amount of was te
added each month.
