Specifications include, but are not limited to: 1. Lead Service Line Inventory a. Review and provide comments regarding the LSL inventory system the city has developed. The City has incorporated all available material information from our work order system, tie cards, assessors database, water main replacement projects and other construction documents into a GIS data management platform. b. Provide guidance with respect to acceptable methods of completing the inventory in accordance with resources and methods identified in the LCRR and the EPA “Guidance for Developing and Maintaining a Service Line Inventory”, August 2022. c. Assist with the development of a predictive model, if appropriate, and document the methodology and outcomes from the modeled results. d. Provide guidance, prepare outreach materials, and coordinate a customer outreach program to solicit material data from customer investigations. e. Provide personnel to conduct investigations of customer-owned materials. For budgeting purposes assume one person, full-time for four weeks, will be required to inventory customer side materials in priority areas. f. Assist with the identification of targeted service locations for DPW staff to utilize the city’s staff and Vactor truck to inspect the service line materials at curb stops. g. Conduct project update meetings at least monthly throughout the duration of the project. At least bi-weekly discussions/virtual calls with project staff are expected to maintain progress and ensure coordination between consultant and City activities. 2. Prepare Lead Service Line Replacement Plan a. There are no known lead service lines in the Portsmouth or Pease Tradeport water systems. There are currently 74 galvanized service lines, which the city assumes at one time may have had, or may still have, lead connectors. The LSL Replacement Plan shall focus on the replacement of these galvanized lines. A draft of this plan is requested prior to May 2024, so funding can be requested, and contracts can be put in place to commence the replacement activities over the summer 2024. The consultant shall prepare a plan that meets the requirements of the LCRR for submittal to the NHDES by October 16, 2024. b. The plan must include public education documents, provide a strategy for outreach and response, outline a funding strategy agreed upon through discussions with the City, and provide a scope of work in a format sufficient to request funds through the DES State Revolving Fund. The plan must also detail the procedure for conducting full lead service line replacement, a replacement prioritization strategy, and a goal for the rate of replacements. 3. Update Lead and Copper Monitoring Plan a. The city has been actively updating the LCR lead and copper sampling list with sites that are known to have galvanized service lines. As a result of new groundwater sources being added to the Portsmouth water system in 2022, the city is in the process of sampling 60 sites twice in 2023. The consultant shall review the sample sites on the Portsmouth and Pease Tradeport active LCR monitoring lists and prepare an updated list that incorporates the findings of the LSLI and meets the requirements of the tiered sampling site requirements set forth in the LCRR.
