Work Plan regarding Freshwater Inflows to the Nueces Estuary
Preamble
The City of Corpus Christi (City), the Nueces River Authority, and the City of Three Rivers are the
owners of, and the City is the principal operator of, the Lake Corpus Christi/Choke Canyon Reservoir
System on the Nueces River. Currently, the Reservoir System is the primary water supply for the City
and the surrounding twelve county area. The Nueces River is also the main source of fresh water to
the Nueces Estuary.
As part of its water rights permit for Choke Canyon Reservoir, the City is required to operate the
Reservoir System in such a way that spills and releases from the Reservoir System and return flows
provide not less than 151,000 acre-feet (acft) per year to the receiving estuaries. After the first
operations plan for the Reservoir System was issued by the Texas Water Commission (predecessor to
the Texas Natural Resource Conservation Commission (TNRCC)) in 1990, the City conducted a
Nueces Estuary Regional Wastewater Planning Study (Wastewater Study) to assess the potential
beneficial impacts of targeting wastewater return flows in the Nueces Delta to substitute, in part, for
releases or pass throughs of inflows from the Reservoir System Phase 11 of the Wastewater Study was
finished in June 1993 and concluded that targeting the return flows would have a beneficial impact on
the productivity of the Nueces Estuary. Based on the findings in the Wastewater Study, two
recommendations were made:
1. Establish one or two demonstration projects to show the project feasibility and to provide
scientific evidence for the degree of productivity enhancements achievable by freshwater and
wastewater diversions to the Nueces Delta; and
2. Establish a scientific monitoring program to routinely collect pertinent data for the
continued operation and improvement of scientific knowledge in the Nueces Estuary.
Currently, both recommendations are being implemented. Construction of the Allison Wastewater
Treatment Plant demonstration project will be completed in September 1997, and the monitoring
program was initiated prior to the construction of the demonstration project. In addition to
implementing the recommendations of the Regional Wastewater Study, the City has been working with
the Nueces Estuary Advisory Council (NEAC) and the TNRCC to gather information on the operating
plan and other data on the importance of freshwater inflows to the Nueces Estuary. As a result of that
ongoing work, the reservoir operating plan was amended in 1995 (1995 Agreed Order).
The 1995 Agreed Order sets targeted monthly inflow amounts based on the amount of water
impounded in the Reservoir System. Under the 1995 Agreed Order, the City is required to meet
targeted inflow amounts of 138,000 acft, when the water impounded in the Reservoir is greater than or
equal to 70 percent of storage capacity, and 97,000 acft, when the water impounded is less than 70
percent but greater than or equal to 40 percent of storage capacity, by a combination of releases and
September 24, 1997
spills from the Reservoir System and return flows. The 1995 Agreed Order also provides that the City
may reduce the inflows during times of drought in any month when water impounded in the Reservoir
System is less than 40 percent but greater than or equal to 30 percent and the City has implemented
Condition II of the City Drought Contingency Plan, and that the City may suspend the inflows when
the water impounded in the Reservoir System is less than 30 percent and the City has implemented
Condition III of the City Drought Contingency Plan.
Since the adoption of the 1995 Agreed Order, the Nueces Watershed and the Reservoir System has
experienced a severe drought. As a result of this drought, the City implemented some of the drought
contingency provisions of the 1995 Agreed Order in addition to ongoing water conservation measures.
The City also secured additional supplies from Lake Texana. On March 25, 1997, the City filed a
request with the TNRCC to amend the 1995 Agreed Order. Subsequently, the City requested a
continuance in order to consider a proposal by the Coastal Bend Bays Foundation (CBBF) to redirect
wastewater return flows into the Nueces Delta in exchange for modifying the 1995 Agreed Order to
allow the City to suspend riverine inflows when the Reservoir System capacity is less than 50 percent
and when the City has implemented all of the measures of Condition I of its Drought Contingency Plan.
The City discussed its request with the staffs of the TNRCC, Texas Parks and Wildlife Department
(TPWD), Texas Water Development Board (TWDB), and Texas General Land Office (GLO). Under
the Cita s proposal, a total of 20 million gallons per day (MGD) of wastewater discharges would be
redirected into the Nueces Delta as a substitute for riverine flows.
Based on these discussions, in June 1997, these groups entered into an "Agreement in Principle" to
support the development of a work plan for implementing the City and CBBF proposal to provide
long-term freshwater inflows to the Nueces Estuary System. On June 25, 1997, based on the
"Agreement in Principle," the TNRCC granted the City temporary relief until October 15, 1997, from
the freshwater inflow requirements under the 1995 Agreed Order when the Reservoir System capacity
is below 50 percent. The "Agreement in Principle" included an understanding that the City would
request that the TNRCC amend the 1995 Agreed Order, under which the City is currently operating
the Reservoir System, based on a work plan for redirecting wastewater return flows to the Nueces
Delta.
To assist in the development of the work plan, a Steering Committee and advisory subcommittees were
established to examine specific issues identified in the "Agreement in Principle" and to identify and
resolve other issues. The Steering Committee was comprised of the City, CBBF, and staffs of the
TNRCC, TPWD, GLO, and TWDB. Three advisory subcommittees were established to examine
biological, hydrological, and water quality/permitting issues. The following work plan addresses these
issues.
2
September 24, 1997
Work Plan
I. Proposal
A. Objectives
1. The City of Corpus Christi will, subject to obtaining and in accordance with the
applicable permits, redirect municipal and industrial return flows of not less than 1800 acre-feet per
month (approximately 20 MGD) to the Nueces River delta according to the following anticipated
schedule:
a. Phase 1 (2.0 MGD)
Allison Wastewater Treatment Plant (WWTP), 2.0 MGD.
Completion in October 1997.
b. Phase 2 (8.0 MGD)
I. Industrial. Koch, 3.0 MGD.
ii. Municipal. Broadway WWTP, 4.5 MGD.
iii. Municipal. Allison WWTP, 0.5 MGD.
Completion in 2-4 years from the date of the Order.
c. Phase 3 (10.0 MGD)
Greenwood and/or Oso WWTP, 10.0 MGD.
Completion in 4-6 years from the date of the Order.
2. The City, in cooperation with the Steering Committee and the Nueces Estuary
Advisory Council (NEAC), will monitor the discharge of the redirected return flows on the Nueces
Estuary, assess the effects of these return flows to the Nueces Estuary system, and evaluate whether
the redirected return flows and other changes create a need to modify the existing reservoir system
management plan to optimize water availability for permitted uses and freshwater inflows to the
Nueces Estuary system.
3. The City and TPWD, in cooperation with the Steering Committee and NEAC, will
develop a program to educate and inform the public on the importance of freshwater inflows and water
conservation to the ecology of the Nueces Estuary system, the need for this work plan, and the
resulting benefits to the surrounding communities and their economies. The City and TPWD, in
cooperation with the Steering Committee and NEAC, will also develop a schedule for implementing
this educational program.
B. Relief
In consideration of the City's commitment to this work plan, the parties to this work
plan agree to support the City's proposed revision to the 1995 Agreed Order as follows:
3
September 24, 1997
1. When water impounded in the Reservoir System is less than 70 percent but greater
than or equal to 50 percent of storage capacity, a targeted amount of 97,000 acre-feet is to be delivered
to Nueces Bay and/or the Nueces Delta by a comtmation of releases and spills from the Reservoir
System as well as diversions and return flows. In accordance with the monthly schedule and except as
provided otherwise in the 1995 Agreed Order, targeted inflows to Nueces Bay and/or the Nueces
Delta shall be in the acre-foot amounts as follows:
January 2,500 July 4,500
February 2,500 August 5,000
March 3,500 September 11,500
April 3,500 October 9,000
May 23,500 November 4,000
June 23,000 December 4,500
It is expressly provided, however, that releases from the Reservoir System storage shall
not be required to satisfy the above targeted inflow amounts as calculated in Paragraph 1.d. of the 1995
Agreed Order.
2. Since relief from freshwater inflow requirements contained in the Certificate of
Adjudication 21-3214, and based on reservoir system operating rules contained in the 1995 Agreed
Order, are contingent upon the implementation of the City's Drought Contingency Plan adopted in
1987 and as amended in 1996, any subsequent changes to demand reduction measures during the
implementation of the work plan may constitute cause for review and action by the TNRCC as
provided by Section VI below.
3. Provided the objectives of this work plan are being met according to the schedules
set forth in Section II, below, and this work plan is in effect by order of the TNRCC, in any month
when water impounded in the Reservoir System is less than 50 percent of storage capacity, the City of
Corpus Christi may suspend the passage of inflow from the Reservoir System for targeted inflow
purposes to Nueces Bay, when the City has implemented and required its customers to implement, at a
minimum, all measures of Condition I as described in the City of Corpus Christi's "Water Conservation
and Drought Contingency Plan," as amended. These measures are:
a. daily monitoring of lake levels;
b. check operation of city -owned or leased wells for mechanical or electrical
problems;
c. discuss water conservation and rationing possibility with City's wholesale
customers, including the San Patricio Municipal Water District, Alice Water Authority, City of Mathis,
and Beeville Water Authority;
d. discuss water conservation and rationing possibility with other holders of
Nueces River water rights not controlled by the City and notify the Nueces River Authority of all
actions being taken;
4
September 24, 1997
e. discuss possibility of a water conservation and rationing program with large
water volume industrial users;
f. City Council declares that water shortage conditions exist and implements
drought contingency plan;
g. request voluntary conservation of water by all users and mandatory
conservation by municipal operations;
h. restrict watering of lawns to specified day or days of the week;
i. restrict watering lawns and vegetation between 10 am and 6 p.m; and
j. make treated wastewater effluent available to public for non -potable
beneficial purposes in accordance with the water right.
4. The City may continue to obtain relief from targeted Nueces Bay inflows in any
month when water impounded in the Reservoir System is less than 40 percent of storage capacity,
provided the City has implemented and continues to enforce all measures of Condition II as described
in the City of Corpus Christi's "Water Conservation and Drought Contingency Plan," as amended.
These measures are:
a. shut off water in ornamental fountains that do not recycle water;
b. repair or shut off defective plumbing allowing the waste of water;
c. restrict use of potable water for outdoor uses such as car washing, dust
control, exterior building, sidewalk, and driveway washing;
d. restrict use of fire hydrants for any use other than fire fighting;
e. restrict the watering of lawns to once every two weeks, with no watering
allowed between 10 a.m. and 6 p.m;
f restrict the watering of vegetation as provided by the City Manager;
g. prohibit the use of potable water by a golf course to irrigate any portion of
its grounds, except those areas designated as tees and greens, and only between the hours of 6 a.m and
10 am on Mondays, Wednesdays, Fridays, and Sundays; and
h. appoint an Allocation and Review Committee.
Additional measures may be implemented as the City Manager deems appropriate.
II. Redirection of Return Flows (Objective 1)
The following sets out schedules for the redirection of return flows to the Nueces Delta. These
schedules are subject to review and revision as provided in Section VI below.
A. Phase 1 (Allison WWTP)
Phase 1 involves the discharge of 2.0 MGD from the Allison WWTP demonstration
project to the South Lake area of the Nueces Estuary. This project has been approved and permitted

3. Monitoring.
Monitoring must be performed according to the program described in Section
111, below.
III. Monitoring
A monitoring program will be implemented to detect the occurrence of impacts, particularly
degradation, due to the wastewater discharge on biota and wetlands in the immediate Nueces Delta
discharge zone and along the gradient from the discharge site out through the delta to the upper edge
of Nueces Bay. This biological monitoring program will be carefully designed after all proposed details
of the wastewater discharge project (including source and quantity of wastewaters, their composition,
the location of the exact discharge site, and an operating plan for discharging) are known and decided.
The scope of the bio -monitoring work will then be developed jointly by the City, resource agencies
(TPWD, TNRCC, GLO), and knowledgeable research scientists from the University of Texas Marine
Sciences Institute and Texas A&M University Corpus Christi. Intensive, multi -seasonal monitoring
and sampling would be planned for a minimum length of time starting one year prior to and extending
8
September 24, 1997
five years after the start of the wastewater return flow project. Further monitoring after the initial five
year period would be on an annual basis.
1. Continuous monitoring of water -column salinity and dissolved oxygen (DO) with
automated hydrosonde units at three or more points ranging from near the wastewater discharge outfall
out to the edge of Nueces Bay in order to detect the physical extent of wastewater mixing.
2. Water -column primary production (biomass by chlorophyll), productivity
(photosynthesis), total organic loading (particulate and dissolved), and phytoplankton and zooplankton
taxonomy to detect population changes in plankton communities.
3. Emergent vegetation measurements (plant cover/biomass, species composition, and
soil chemistry) along fixed ground transects three times per year (spring, mid -summer, and late fall).
The number and location of stations would be chosen to detect responses of marsh plant communities
to lower salinity water and higher loads of nutrients and trace metals. This sampling scheme would
closely follow the discharge gradient. Aerial, color infrared photography will be performed each
October for five years over the entire lower delta (around the discharge sites out to the open bay).
After five years, the photography could be done every two years.
4. Benthic sampling of invertebrates and other infaunal populations would
quantitatively determine the effects of the freshwater diversions and the wastewater discharges.
5. Nekton sampling would be done in the delta for larval/juvenile fish, shellfish, and
other invertebrates by trawling or seining. This would complement sampling being done on a regular
basis by the TPWD Coastal Fisheries in the open waters of Nueces Bay.
6 Sampling of mammals, reptiles, and bird populations would be done in the delta
habitat areas.
7. A program of contaminant sampling and analysis will be designed to monitor
bioaccumulation of key toxic materials (e.g. mercury, zinc, lead, etc.) found in the wastewater
discharges. This program would focus on contaminant levels in the sediments and in tissue of sessile
(stationary) plant and animal populations (e.g. oysters) and be designed to detect any gradient or
bioaccumulation between the discharge outfalls and the open waters of Nueces Bay. This program will
be designed and coordinated with TNRCC, the state and local Health Departments, and other agency
programs.
IV. Evaluation (Objective 2)
A. Compliance with this Work plan shall be monitored by a Steering Committee comprised of
one or more representatives from the City, the Coastal Bend Bays Foundation (CBBF), TNRCC,
TPWD, TWDB, and GLO.
9
September 24, 1997
B. The Steering Committee, in cooperation with NEAC, will evaluate the monitoring of the
wastewater return flow projects and other changes to the ecology of the Nueces Estuary to assess the
benefits of the return flows to the Nueces Estuary. At the request of any member of the Steering
Committee, but no later than October 1, 2002, and periodically thereafter, the Steering Committee will
determine whether there is a need to revise the existing monitoring programs and whether there is a
need for a new reservoir system management plan to optimize water availability for permitted uses and
freshwater inflows to the Nueces Estuary system Recommendations for revisions to the monitoring
programs or reservoir management plan will be forwarded by the Steering Committee to NEAC.
V. Educational Program (Objective 3)
By April, 1998, the City and TPWD, in cooperation with the Steering Committee and NEAC,
will develop a program to educate and inform the public on the importance of freshwater inflows and
water conservation planning to the ecology of the Nueces Estuary system, the need for this work plan,
and the resulting benefits to the surrounding communities and their economies. The City and TPWD,
in cooperation with the Steering Committee and NEAC, will also develop a schedule for implementing
this educational program. Upon approval of the program by NEAC, the City will implement the
program.
VI. Review and Reconsideration of Workplan
A. Upon completion of the work plan, the City shall provide not less than 20 MGD to the
Nueces River Delta through the discharge of treated effluent of acceptable quality for the purposes of
maintaining the proper ecological environment and health of related living marine resources. This is to
be accomplished in Phase 3 by the expansion and increased discharges from wastewater treatment
facilities owned by the City. Should it appear that these wastewater discharges will not amount to at
least 20 MGD by the completion of all three phases of the work plan, then the Steering Committee and
NEAC shall meet and develop recommendations on how the remaining amount shall be provided,
either from riverine flows or other acceptable sources.
B. The City, should it determine that it will not meet any deadline contained in the work plan or
will fail to cavy out the objectives of the work plan, must so inform the members of the Steering
Committee as well as the Executive Director of the TNRCC. This notice must be provided in writing
as soon as practical after the City's determination and as much in advance of any deadline or projected
failure as possible. The City, should it determine that there are better or more feasible alternatives for
meeting the objectives or the work plan, may propose revisions or additions to the work plan to the
Steering Committee.
C. Process for Revisions, Extensions, or Determining Compliance
I. Notice by the City or a written request from one or more Steering Committee
members stating that a deadline is not being met, the objectives of the work plan are not being met or
10
September 24, 1997
that there are better or more feasible alternatives for meeting the objectives of the work plan, shall
cause the NEAC to be convened for a full review.
2. If the NEAC finds that a deadline has been missed, that the objectives are not being
met or that there are better or more feasible alternatives, the NEAC shall certify such findings to the
Executive Director of the TNRCC, together with any recommendations for deadline extensions,
revisions or amendments to the work plan, or for reversion to the terms and conditions of the 1995
Agreed Order.
3. As provided in Section 4 of the 1995 Agreed Order, the Executive Director shall
forward the findings and recommendations of NEAC to the TNRCC, together with any comments of
the Executive Director, and shall set the matter on the next available Commission agenda for
consideration. The failure of the NEAC to make affirmative findings or recommendations will not
prevent the Executive Director from setting the matter on a Commission agenda.
4. The TNRCC upon a showing of good cause, may approve extensions of deadlines
or revisions or amendments to the work plan. Should the TNRCC fail to approve any deadline
extensions or ford no good cause exists for failure to meet the objectives of the work plan, the monthly
inflow targets and drought contingency provisions of the 1995 Agreed Order shall be reinstated, unless
otherwise ordered by the TNRCC.
D. By consenting to the adoption of this work plan, no party admits or denies any claim, nor
waives with respect to any subsequent proceeding any interpretation or argument which may be
contrary to the provisions of this work plan. The City, the Executive Director of the TNRCC, TPWD,
TWDB, GLO, and CBBF reserve the right, at any time, to request the TNRCC to amend the monthly
targeted inflow and drought contingency provisions or other provisions of the 1995 Agreed Order or
as it may be amended. The order implementing this plan shall provide that nothing therein affects the
authority of TNRCC or its Executive Director to enforce its orders and regulate water and water
quality under Chapters 11 and 26 of the Texas Water Code or other applicable law.
VII. Temporary or Interim Restoration of Inflows
A. Documented Emergencies. In the event of a documented emergency, the Executive
Director of the TPWD may request the TNRCC to order a temporary return to the freshwater inflow
