Who agree to amend the original Agreement, as follows:
EXHIBIT B, PART I —A. PROJECT DESCRIPTION
The description of the proposed WWTP systems and evaluation tasks that the facility planning effort is
to focus upon has been modified to include the following additional WWTP systems and evaluation
tasks:
12. Develop and evaluate alternatives than can both thicken waste activated sludge (WAS) and dewater
anaerobically-digested sludge.
13. Evaluate the condition of the concrete walls, ceiling and floor slab in the tunnels between the
Rectangular Primary Clarifier Building and the Old Compressor Building and between the Old
Compressor Building and the Anaerobic Digester Building.
a. Visually assess the existing condition of the structural reinforced concrete and joints in the
concrete.
b. Prepare a report on inspection findings, which contains recommendations for replacement and
opinion of the probable construction cost.
EXHIBIT'A' - Page 1 of 8
14. Prepare bidding documents for the selected alternative to both thicken WAS and dewater
anaerobically-digested sludge.
a. The plans and specifications prepared for this design are to be prepared as a stand-alone set of
contract documents for bidding by general contractors with a construction contract to be
awarded by the CITY to the lowest, responsive and responsible bidder.
b. The level of effort for this amendment is based on the WAS flow not being pumped to an
equalization tank prior to thickening, but will be pumped directly to the selected thickening
equipment when it is in operation.
15. Bid Phase Engineering Services for the thickening and dewatering improvements as identified in this
agreement amendment will be initiated after receiving approval from IDEM for a construction permit
application if determined to be necessary.
EXHIBIT B, PART I — B. SCOPE OF SERVICES
The engineering scope of services have been modified to include the following additional activities:
4. Sludge Thickening and Dewatering Evaluation Services
a. Review and evaluate January 2014 to April 2017 plant operational data to determine daily
average, maximum month, and maximum week primary sludge and WAS volumes and dry
solids quantities.
b. Determine the daily average, maximum month, and maximum week volume and dry solids
quantities of digested sludge.
c. Project the end of planning period daily average, maximum month, and maximum week WAS
volumes and dry solids quantities. These values will be estimated by both assuming a
proportionate increase in WAS volume and dry solids amount to the projected increase in
influent daily average flow and pollutant loadings.
d. Using calculated current and future primary sludge, WAS, and digested sludge volumes and
quantities, determine and evaluate appropriate technologies to both thicken and dewater
sludge. Technologies to be assessed will include a belt filter press, centrifuge or screw press.
e. Assist in coordination of up to three (3) pilot tests of appropriate technologies. Coordination
activities may consist of the following:
1) Discussion with equipment representatives to schedule pilot tests.
2) Assist the CITY with coordination of the pilot testing and clarification of the minimum
