P.O. Box 9277
City of Corpus Christi, TX 78469-9277
RE: Request for Additional Fee-Amendment No. 17-Leachate Conveyance System
Cefe F. Valenzueia Landfill, Disposal Cell 1 A - Project -5aa~
Dear Mr. Stowers;
CP&Y, Inc, is respectfully requesting approve! of Amendment No. 17 to our contract for the above
referenced project.
The current design of the. Cefe F. Valenzueia !_andfill will ultimately require installation of eleven {ii)
leachate collection sumps in Unit 1. At the present time two Leachate Collection sumps have been
installed in two of the three landfill cells that have been constructed at the Cefe 1=, Valenzueia Landfill
since late 2007.
As the landfill develops sequentially, it will become more difficult to adequately control, monitor and.
manage the iandfdl conveyance systems and ether landfill systems overall. The Landfill footprint
perimeter of Unit 1 is approximately 12,000 feet in length and the grade differential around the site is
minimal.. This limited grade differential and the long distance around the site is expected to require
considerable design attention to properly manage the movement of landfill liquids around this perimeter.
The currently constructed perimeter leachate collection system consists of a 4" forcemain along the north
end of the site, connecting sumps 3D and ~4A, that discharges into a main discharge line near cell 3D.
This discharge line is a buried 4" diameter MDPE pipe that branches east of the landfill and discharges
into the two evaporation ponds constructed on the site. The 4" diameter HDPE perimeter leachate
forcemain connecting sumps 3D and 4A will be extended and connected to leachate sumps 1-A1and 1A2
for Cell 1A.
Work to be performed under this Amendment 17 will consist of the following:
1. iden#ify the physical conditions far the conveyance system design under the current
permit requirements for Unit 1.
2. Establish the anticipated quantities to be recirculated or managed as part of the liquids
conveyance system for Unit 1.
3. Prepare conceptual designs showing alignment and locations of the conveyance system
and future installations or modifications to the existing permitted leachate management
system for this portion of the Landfill.

4. Prepare hydraulic model and perform hydraulic analysis of the conceptual conveyance
system to identify preliminary sizing of conveyance piping.
A separate portion of the ieachate collection system will eventually be required for the southern portion of
Unit 1, to convey ieachate from Cells 2A, 2B, 2C, 3A, 3B and 3C eastward and tie-in to the ieacha#e
evaporation pond system. Development of these cells requires consideration of the future pumping
requirements and demands for maintaining proper levels for compliance in all teachate collection sumps.
Work under this amendment will be performed to address-these additional cells and the need to increase
the quanti#y and duration of the pumping of ieachate. This may require resizing the currently constructed
system or this portion of the system to serve the southern cells. The resizing wilt be determined based on
anticipated conveyance and production rate of ieachate for the completed landfill.
The quantities of these liquids may be significant and may influence the required design features. An
estimated quantkty wil! be developed-for each Cefl and will be used to establish a basis far development of
the conveyance liquids management system, This task wilt focus on determining the most viable
alternatives, and establishing the technicai requirements and conceptual designs as the s[ie development
progresses into adjacent sectors. The overall ieachate conveyance system will be designed far the
required management of liquids that are pumped or generated during the operation of the facility:
The work described under this amendment does not include system design or evaluation far recirculation
of liquids or potential liquids, such as groundwater water or condensate, to the working face or interior
landfill areas. Construction drawings for installation of any ieachate conveyance piping system are not
included in this scope of work. Focus of these work efforts is limited ko estimating the quantities of liquids
to be conveyed, alignment and sizing of the conveyance system, and proper operation to meet future
Heads of the landfill liquids management.

CPY, Inc.
