Preliminary Engineering Report, August 2005, prepared by Engineer and the Supplemental PER,
September 2005 prepared by Engineer and modified through work performed in Amendments No. 1
and 2 up until this time that Amendment No. 3 replaced Attachment A, Item B, Part 2 of the Original
Agreement and those amendments. The services to be provided under this Amendment No. 3 include
permitting assistance; stream modeling; solids improvement study; preparation of technical
memoranda; field surveys; geotechnical services; preparation of technical specifications, drawings, and
construction phase services for the influent lift station; design, bid and pre -award services for
Construction Package No. I as presented in the following paragraphs and as contemplated to be added
by the Original Agreement, Attachment A, Item B, Part 2 — Detailed Design and preliminary design of
Construction Package No. 2 up to the point when Engineer was directed by Owner to suspend design.
Description of Proiect.
Modifications will be made at the SEWRP to provide a rated plant flow of 31.5 mgd with effluent
design limits for Plant 4 of 5 mg/1 BOD, 5 mg/l TSS, 8 mg/l TN, and 1 mg/l TP. It is anticipated
that these effluent design limits will meet or be lower than the actual Texas State permit
requirements. Any changes by the State, prior to completion of the Value Engineering study, that
are more stringent, but do not require salt removal or allow for direct reuse of effluent, and affect
the plant design will be acconunodated into the design at no additional cost to the Owner. Any
changes in effluent permit limits that affect the plant design that are identified after completion of
the Value Engineering study and impact the design, Engineer's compensation will be adjusted
based on mutual agreement, in writing, by both parties.
The work shall involve Engineer preparing one design package and one construction package to
meet the plant flows and effluent design limits described above and initial design work on a second
construction package. Notwithstanding anything to the contrary herein, the work of Engineer
hereunder, in addition to other work described herein unrelated to the design of the SEWRP, shall
be sufficient, after construction in accordance with Engineer's work hereunder, to meet in all
respects the effluent quantities, and effluent design limits, described in this "Description of
Project", first paragraph, above.

L. Stream Modeling
Provide an evaluation of alternative effluent discharge locations to the North Fork
Double Mountain Fork of the Brazos River (NFDMF). Potential discharge locations
include the Canyon Lakes, near the SEWRP, and below Lake Ransom Canyon, which
is the existing discharge location.
Expand the TCEQ QUAL-TX model to include the Canyon Lakes and the NFDMF
from below Lake Ransom Canyon to the Route 380 bridge near Post, Texas. A separate
hydraulic model, HEC-RAS will be constructed from Canyon Lake I to Buffalo
Springs Lake for the purpose of developing the hydraulic coefficients and exponents
required for the QUAL-TX model. The coefficients and exponents for the river
segment from below Lake Ransom Canyon Lake to Route 380 were developed as part
of the 1990 B&V Water Quality Modeling Study, which was conducted as part of an
Engineering Plan for upgrades to the WWTP. Therefore, a 1 EC-RAS model of this
segment will not be necessary.
Water quality data from 1990 B&V Water Quality Modeling Study and other available
water quality data will be used to calibrate the model, Additional sampling will be
provided to determine the potential presence of thermal stratification provide
background chlorophyll a, a constituent of the algae, which produce DO during
photosynthesis.
2. TCEQ will be contacted regarding the Agency's QUAL-TX model of the (NFDMF)
from the Lubbock WWTPs to Buffalo Springs Lake to clarify the model calibration
approach, and assumptions for CBOD, ammonia decay rates, sediment oxygen demand
(SOD) rate, stream and reservoir re -aeration rates, and stream and reservoir channel
cross -sections. Clarification will be requested on the applicable aquatic life dissolved
oxygen (DO) criterion for the unclassified segment of the NFDMF River above
Ransom Canyon Lake. The segment from below Ransom Canyon Lake to the
confluence of the Double Mountain Fork of the Brazos River is classified with a
"Limited" aquatic life use. The average daily DO criterion for a Limited aquatic life use
is 3 mg/L. It appears that the DO criterion for the unclassified segment is 5 mg/L. A
memo documenting this task will be prepared.
The existing TCEQ QUAL-TX model will be extended to include the Canyon Lakes, I
Page 16 of 31
through 6. And downstream of TCEQ's model, the model will be extended to include
all of Buffalo Springs Lake, Ransom Canyon Lake, and approximately 46 miles of the
NFDMF River downstream to Route 380 near Post, Texas. Development of the
extended model will be based on existing information, which will include the following
sources:
• TCEQ QUAL-TX model input run files for various effluent discharge scenarios
• Flood Insurance Study (FIS) hydraulic models from Lake 1 to 50'h Street in
Lubbock, which is about 1.6 miles downstream of Lake 6 dam.
• GIS aerial photos, 1 foot digital contours, and Digital Terrain Model (DTM) from
the City
• Design drawings with elevation contours of Buffalo Springs Lake
• Appendix D, Water Quality Modeling Study, which was conducted by B&V in
1990 as part of an Engineering Plan for upgrades to the WWTPs. The study
included Streeter Phelps models of the Canyon Lakes and the NFDMF River
from below Ransom Canyon Lake to Route 380. The NFDMF River between
Lake 6 and Buffalo Springs Lake was not included in the study.
B&V modeling staff will conduct limited field reconnaissance of the modeling study
reach, which will consist of driving to various bridge crossings and inspecting and
photographing river and lake conditions. This will not include surveying, which is not
anticipated to be required for this analysis.
3. A hydraulic model of the Canyon Lakes; the free flowing section of the NFDMF River
to Buffalo Springs Lake; Buffalo Springs Lake; and Ransom Canyon Lake will be
configured and run for the purpose of developing hydraulic coefficients and exponents
that will define the hydraulics for the QUAL-TX model. A preliminary review of the
TCEQ's QUAL-TX model suggests that the assumed hydraulic coefficients and
exponents significantly underestimate river velocities in the free flowing section. It is
not expected that a hydraulic model will be required for the new QUAL-TX model
segment below Ransom Canyon Lake to Route 380 because it appears that appropriate
hydraulic coefficients and exponents were developed as part of the 1990 B&V water
quality modeling study. The coefficients and exponents were based on a dye time of
travel study conducted by Alan Plummer and Associates, Inc. (APAI). APAI also
conducted dye studies for the Canyon Lake and the reach from below Lake 6 to Buffalo
Spri ngs Lake for the 1990 study. The dye studies will be used to calibrate the hydraulic
model.
The HEC-RAS program will be used to develop the hydraulic models. The existing
HEC-RAS model, developed for the Lubbock FIS, should be sufficient for the river
reach from Lake 1 to 50`h street. This model will be extended to include the free
flowing section of the NFDMF River from 5e Street to Ransom Canyon Lake dam.
Channel cross sections of this segment obtained by APAI for the 1990 B&V modeling
study will be primary source of data required to build the HEC-RAS model for the free
flowing segment. The survey data will be supplemented by the City's Digital Terrain
Model. Elevation contours, and the design drawing for Buffalo Springs Lake will be
Page 17 of 31
used to develop cross sections for the reservoir. If design drawings for Ransom Canyon
Lake are not available, the cross -sections will be estimated from existing aerial
photography and elevation contours. The HEC-RAS model will be calibrated based on
the dye time of travel study conducted by APAI for the the 1990 B&V modeling study..
The calibrated HEC-RAS models will be run for a range of river flows expected for the
various effluent discharges. The simulated velocities and flow depths will be used to
develop the velocity and depth coefficients and exponents used by the new QUAL-TX
model.
4. The QUAL-TX model developed by TCEQ will be extended both upstream and
downstream as previously described. The study reach for the TCEQ QUAL-TX model
is approximately 9.9 miles from the WWTP to near the Comanche Road Bridge
crossing of Buffalo Springs Lake. The new model will be expanded to include
approximately 8 miles of the Canyon Lakes, the section of Buffalo Springs Lake from
Comanche Road to the dam; Ransom Canyon Lake; and approximately 46 miles of free
flowing river from Ransom Canyon Lake to the Route 380 Bridge. The TCEQ model
was configured using metric units. The expanded models will be configured in English
units to make it more user-friendly.
5. Sampling of Buffalo Springs Lake will be conducted during one sampling period in the
summer of 2006 at five locations in Buffalo Springs Lake and one location in the
NFDMF Brazos River immediately upstream of the headwaters of the lake. Sampling
at each location will include field measurements of dissolved oxygen (DO), pH,
temperature, conductivity, and Secchi disc depth. A near surface water sample will be
collected at each station and analyzed for chlorophyll a by a qualified laboratory.
A Sampling Work Plan will be developed in consultation with TCEQ prior to
conducting the sampling. This plan will describe, at a minimum, the following study
components:
• Monitoring locations;
• Types of samples or measurements;
• Parameters, analytical methods, and, as appropriate, preservation methods and
container requirements;
• Identification of responsibility for implementation of specific study activities; and
• Quality assurance procedures.
After completion of the sampling program, a report describing the study conducted and
summarizing the data obtained will be prepared and submitted to the City for review
and comments.
6. The calibrated models will be used to evaluate scenarios of effluent discharge
alternatives. The alternatives will include various combinations of effluents flow rates
at various discharge locations.. The discharge locations will include the Canyon Lakes,
Page 18 of 31
the NFDMF River near the WWTPs, and increased flow at the existing discharge
location below Ransom Canyon Lake.
The models will be run for up to 10 scenarios developed in the previous task. The
primary consideration for each of the alternatives is impact on DO in the lakes and
rivers. It appears that no alternative should result in a minimum DO concentration
below 5 mg/L from the Canyon Lakes to Ransom Canyon Lake and a minimum DO
concentration below 3 mg/L from Ransom Canyon Lake to the confluence of the
DMNF River; however, these criteria should be verified by TCEQ.
Upon completion of the new QUAL-TX Model, a memo to document the work
completed to that point in the study will be prepared. This will include a preliminary
evaluation of the discharge alternatives. A draft memo will be submitted to the City for
review and comments, which will be addressed in the final version of this memo.
Upon completion of the evaluation of discharge alternatives, a memo documenting the
work for the entire study will be prepared and submitted to the City for review and
comments, which will be addressed in the final version of this memo.
A model using the USEPA program QUAL2K will be developed for the river below
Dam 6 including Buffalo Springs Lake for the purpose of evaluating phosphorus limits
in the SEWRP effluent. The model will be calibrated using the sampling data obtained
earlier and submitted to TCEQ for review and comment. To achieve a consensus with
the model, it is expected that the review process will require a minimum of three
meetings with TCEQ.
9. A QUAL-TX model will be developed for the proposed Lake 7 for the purpose of
determining the allowable flow rate from the SEWRP discharge to the river at the plant
location. The hydraulic coefficients and exponents will be based on the conceptual
design of the lake by HDR as described in a memo to Ches Carthel dated January 24,
2006, and existing elevation contours. The model will be submitted to TCEQ for
review and comment.
M. Deferment of the Plant 3 Design
After the Initial Design Submittal and partial completion of the Second Design
Submittal, the design efforts are to be redirected to expand capacity and improve
effluent quality at Plant 4 in the initial design package and to defer major improvements
to Plant 3 until 2011. Since the completion of Plant 3 design will be deferred until
2011, discontinue all further design of Plant 3.
PHASE 310 — SLUDGE STUDY ANAEROBIC DIGESTER OPERATIONS AND
PROCESS HEATING
The following sections describe the scope of services to be performed as part of an evaluation of the
Page 19 of 3I
anaerobic digester operations and process heating improvements at the City of Lubbock Southeast
Water Reclamation Plant (SEWRP). Also included in the scope is a supporting evaluation to determine
the possibility of using digester gas for process heating and to identify gas cleaning requirements.
The anaerobic digestion facilities at the SEWRP consist of four anaerobic digesters. The digesters are
configured to operate as a two -stage process, with two digesters (Digesters 8 and 9) serving as primary
digesters and the remaining two functioning as secondary digesters (Digesters 6 and 7). The feed to the
primary digesters is a blend of primary solids (PS) and scum from the primary clarifiers and thickened
waste activated solids (TWAS) and secondary scum from gravity belt thickeners (GBTs). Following
primary digestion, the solids are transferred to the secondary digesters for storage and settling. The
secondary digesters have provisions for decanting the supernatant to increase solids concentrations in
the digester effluent.
The existing digester operations at the Plant are hampered by several issues:
Settleability of Digested Solids. The supernatant from the secondary digesters is currently
returned to the head of Plant 2 for treatment along with the filtrate streams from thickening and
dewatering. The settling characteristics of the digested solids in the secondary tanks are poor,
resulting in high suspended solids concentrations in the supernatant to Plant 2.
Digester Heating. The Plant experiences problems attaining the required process temperatures
in the anaerobic digesters and maintaining the mesophilic temperatures. The potential reasons
for the reduced heating capacity are thought to be the quantity of water in the digester feed
and/or excessive transmission losses from the primary digesters.
Digester Gas Handling and Utilization. The anaerobic digestion process at the plant is
attractive from an energy perspective in that it is typically a net producer of energy that can be
used to offset part of the energy requirements for process heating. As part of this study, the use
of digester gas for process heating and the gas cleaning requirements for making most effective
use of digester gas will be evaluated.
The anaerobic digester operation, process heating, and gas handling and utilization evaluations
to be undertaken as part of this study have been grouped under the following tasks.
Anaerobic Digestion Process Evaluation
The major elements of this phase of the study will include:
Review Historical Data to Determine Critical Operating Parameters.
Historical data from the anaerobic digestion facilities will be reviewed to define critical
operating parameters, including flow volumes, flow characteristics, and patterns at critical
locations in the digestion process. The digester operations data identified during the project
initiation meeting will be collected by the Owner and provided to the Engineer. Data to be
collected could include, but not be limited to, digester feed rates, feed and effluent sludge
characteristics, primary sludge pump operating patterns, digester operations data, operating cost
Page 20 of 31
information, and gas production and usage data.
2. Assess Condition of Existing Digestion Facilities.
Walk-throughs of the existing facilities and interviews with operations and maintenance
(O&M) staff will be conducted to identify areas of concern relative to operability,
maintainability, and O&M costs for the digestion facilities. Assessments will be based on
visual inspections, current age of the equipment and comparisons of similar equipment at other
plants. Recommendations for equipment, structures, valves, piping and other associated
equipment to be replaced will be provided.
3. Develop Capacity Requirements for Digestion Facilities.
This task will include projecting future flows and loads to the anaerobic digestion facilities and
determining the process capacity requirements based on the collected data. The areas of greatest
concern for near term and long-term action will be identified and the design parameters for the
digestion system improvements will be developed.
A mass balance model for the solids processing facilities will be developed for current and estimated
future loads to determine the impact of potential changes to existing operations. The model will
consider solids loading and hydraulic issues.
4. Develop Digester Upgrade Alternatives.
The results from the capacity assessments and the evaluation model will be used to develop alternatives
for digestion process upgrades. The key elements to be considered in developing the alternatives will
include:
• Obtaining a More Concentrated Primary Sludge. Additional thickening of the PS will increase
the solids concentration in the digesters and will increase the solids content in the digester
effluent to the dewatering units. An added advantage of thickening PS would be the reduction
in sludge heating loads since there is less water to be heated.
• Providing a Homogenous Sludge Feed to the Digesters. Blending PS and TWAS upstream of
the digesters to ensure a homogenous feed to the digesters may improve digestion process
performance.
• Providing supernatant treatment for secondary digester decant or sidestream thickening of the
digester contents to eliminate the need for supernating.
Page 21 of 31
Digestion Process Heating
The following tasks will be performed to determine the current and future process heating loads and to
determine the best fuel choice for digester heating.
1. Determine Digester Heating Loads.
An energy model for the digestion facilities will be developed to determine current energy use for
process heating. Typically, digester heating loads vary throughout the year due to seasonal changes in
ambient temperatures. These seasonal temperature variations will be taken into account while
determining the digester heating loads. Subsequently, the capacity of the existing digester heating
equipment will be compared to the estimated heating loads to determine the adequacy of the heating
equipment. Potential exists for reducing the energy consumption by (1) Providing a thicker feed to the
digesters to reduce heating loads, and (2) Insulating Digester 9 cover to reduce transmission losses from
the primary digesters.
2. Evaluate Heating Fuel Options.
The historical digester gas production at the plant will be reviewed and the anticipated gas production
for the future will be estimated based on projections of future digester loadings.
The upgrades required to improve the use of biogas for all heaters, with natural gas used only as an
emergency backup will be evaluated as part of this task. The life cycle costs for gas cleaning facilities
to clean gas to be used in the boilers for heating the digesters will be developed. The energy model
developed under Task I will be used to determine the energy requirements for comparison purposes.
Digester Gas Treatment
The gas cleaning requirements for using digester gas in the boilers for process heating will be
evaluated. Cleaning options to be considered include: use of iron salts, gas scrubber(s), and refrigerant
type gas dryers.
A gas analysis will be performed to determine the concentrations of volatile organic compounds, sulfur
compounds and siloxanes in digester gas to determine the gas cleaning requirements. The engineer will
advise the owner on collecting gas samples and transporting the samples to a laboratory for determining
biogas equality.
The gas cleaning requirements will depend on the gas utilization scheme and selection of the
appropriate treatment technology for each contaminant will impact the overall costs for the gas cleaning
operation.
Develop Capital and Operating Costs and Implementation Schedule
Conceptual designs will be developed for two digester improvement alternatives and two digester gas
utilization alternatives. Capital and operating costs and non -monetary factors impacting the decision
Page 22 of 31
will be developed for each alternative. A net present value analysis would be used to compare the
alternatives.
A schedule for implementation of proposed improvements including final design, bidding, and
construction phase services will be provided.
