In the recent past, the City decided to evaluate alternate chemical products to effectively address. odor complaints and reduce corrosion of components in the wastewater collection system. A part of this evaluation was completed under E16264-TA21-Wastewater Collection System Odor Control Chemical Assessment. This involved a preliminary evaluation that included historical review,sampling and analysis,drivers and treatment goal selection to address odor and corrosion issues of concern within the City's collection system. Based on review meetings available funding, four (4) sites from the Oso Basin- (Airline LS, McArdle Trunk Main, Everhart/Staples LS and Wooldridge LS) were selected for implementation. Arcadia LS that send flows Oso, Greenwood or Broadway WWTPs was also evaluated but is currently not included as a part of full-scale demonstration because of low observed H2S levels during field sampling. Under El 6264-TA 37-Wastewater Collection System Odor Control Chemical Assessment, additional field sampling and bench-scale testing was completed to further define the most appropriate chemical.This level of effort is required to complete Task 5- Selection and Implementation to assist the City through procurement process in implementing a long-term and sustainable odor control program. The purpose of this task authorization will be to continue assisting the City with additional effort to implement a 7-8 month full-scale demonstration. This additional effort can be attributed to the following factors: • Changes in implementation/procurement strategy • The number of service providers for odor control are limited due to its specialized nature and patents which may lead to sole sourcing and may not comply with the City's current procurement strategy. • To develop a strategy to avoid sole sourcing and ensuring a competitive bid process • Possibility of a full-scale trial in the initial implementation project • Additional modeling assistance • Data review assistance through the eight(8)month program • Preparation of summary letter with long-term recommendations 1 Exhibit A Page 2 of 6 vyJS - 4 r, LNV SCOPE OF WORK ADDITIONAL SERVICES: TASK 0009-GENERAL ENGINEERING Task 49.Odor Control Chemical Selection and Implementation The purpose of this task is to provide continued assistance to the City in the implementation of odor control chemicals at identified sites. The following sub-tasks are anticipated for a successful odor control program: • Procurement Assistance: Assist the City for developing a draft and final RFP document. This additional effort will be used for vendor coordination, incorporating new chemical specifications if needed, developing scoring criteria and matrix to evaluate vendor proposals once submitted. This effort also includes site visits with vendors to identify feed locations based on vendor specific constraints. • Additional Modeling Assistance: Assist the City using the City's wastewater model in readjusting flow locations and addressing vendor information requests for pump run times, flow paths, etc. • System Installation Oversight: Support the City during the start-up phase as required. Engineer to assist in coordination of monitoring efforts between the City and the selected vendors during this start-up period. • Data Analysis: Provide assistance to the City for analysis of liquid-phase and gas-phase data collected during the full-scale demonstration. The City team will continue monitoring post odor control training and share data with the Engineer,and monthly meetings will be held to discuss the performance of the full-scale demonstration and provide support as needed to address issues that may arise during operations. Fee is based on 112 hours. • Summary Letter: The Engineer will prepare a summary letter for the City at the end of full- scale demonstration which will include an evaluation of results from the full-scale demonstration and recommendations for long-term implementation at the identified four(4) locations. Deliverables: i. The Engineer will prepare chemical/vendor specifications (to include performance criteria, scoring matrix,etc.)for City's review. ii. Summary letter at the end of full-scale demonstration. 2 Exhibit A Page 3 of 6 O,. US Gid GJ LNVo X651 MeetinLs: i. Monthly coordination calls/meetings with the City to discuss performance of full-scale demonstration and assist in troubleshooting. Basis of Fee:Difficult to accurately estimate the level of effort at this time.It is assumed that a number of tasks will be performed by the City and the Engineer.Engineer's fee may be greatly impacted by the assumed division of responsibilities City Responsibilities: i. The City will lead the procurement and vendor selection procedures.The Engineer will assist with the process as detailed above. ii. The City will collect liquid-phase and vapor-phase data following vendor odor control chemical addition system implementation with a frequency of once per week during dosage optimization phase and once every month for the remainder of the full-scale demonstration. The City will provide the data to the Engineer in an Excel format for analysis. iii. City staff will supply sulfide sampling equipment(LaMotte dissolved sulfide test kit for liquid- phase data collection,and OdaLog®units for vapor-phase data collection). Schedule: The Engineer's services shall be performed in a timely manner consistent with sound professional practices.The time limits set forth in the schedule shall include allowances for reasonable and expected review time by the City and approval by authorities having jurisdiction over this project and shall not be allowed as cause for delay or adjustments to the schedule. Delays caused by review times by the City exceeding those anticipated by the Engineer's schedule are cause for adjustments in the schedule. Any adjustments made to the agreed upon schedule shall be made in writing and accepted by both parties. The schedule presented is a preliminary estimate and may change depending on the improvement solutions selected. The Engineer shall begin work immediately upon receipt of the executed Task Authorization and/or Notice to Proceed(written or emailed).The work under this task authorization is anticipated to be complete in accordance with the following schedule.
