SUBJECT: Proposal for Environmental Activites Related to New Former Oyster Point Landfill Water Line Monitoring Stations South San Francisco, CA
CSS Proposal 050420
Dear Mr. Kaufman:
Thank you for the opportunity discuss the City of South San Francisco’s (the City’s) anticipated need to monitor and maintain monitoring stations along the relocated Cal Water supply line supporting the redevelopment of the Former Oyster Point Landfill. We welcome the opportunity to provide you with this proposal to support the City in this effort. CSS Environmental Services, Inc. (CSS) is uniquely qualified to provide you with the services described herein as we have been providing the City with compliance monitoring services at the former Oyster Point Landfill since 2008. The monitoring is required by the present RWQCB Order No. 00-046 which specifies Waste Discharge Requirements (WDRs) for the City as discharger and owner of the Oyster Point Landfill property and has been in place since June of 2000. CSS completes groundwater monitoring, storm water inspections and monitoring, and landfill gas monitoring activities for the City and provides associated reporting and project management of these activities. In addition, CSS has experience performing compliance monitoring at several other closed landfills regulated by the RWQCB and local county agencies, including:
• Former Smith Ranch Road disposal site. CSS performed monitoring and reporting activities at the current Captain’s Cove condominium site for the homeowner’s association. At our recommendation, the Marin County Environmental Health Department (MCEHD) and the California Integrated Waste Management Board (now Cal Recycle) closed the site after years of declining concentrations of landfill gas in 2007.
• Former Horst Hanf Landfill. CSS is providing on-going environmental compliance monitoring at this closed landfill and current Bayview Business Park regulated by Cal Recycle and the MCEHD.
• Former San Quentin Solid Waste Disposal Site. CSS provides environmental compliance monitoring at this closed solid waste disposal site and current Home

PROPOSED SCOPE OF WORK
In support of the City’s requirements found in their pending Utility Agreement with Cal Water, CSS sees the following scope of work tasks and estimated annual budget based on time and material charges according to our existing Oyster Point fee schedule. 1 Meetings
CSS anticipates attending two meetings with the City, the Developer, Cal Water and/or the RWQCB as needed each year. $1,450 per year
2 Preparation and Submittal of Quarterly Reports
The Agreement requires the City to submit quarterly reports to Cal Water including semiannual monitoring reports (already contracted with CSS by the City), quarterly readings of groundwater elevations in existing monitoring wells (presently performed quarterly and reported semi-annually by CSS for the City), the latest ground elevation surveys and ISO settlement maps, sampling results from any water station. As semi-annual reports are currently prepared two additional quarterly reports are required per year. $4,800 per year
3 Survey of Selected Fire Hydrants
The City is required to survey selected fire hydrants, capturing any settlement at 30 days, 1 year, 3 years and 5 years after water line tie-in. $1,350 per event 4 Develop ISO Settlement Map
The City is required develop a ISO Settlement Map after water line tie-in and every 5 years thereafter. CSS assumes that ground elevations will be surveyed across the landfill to determine settlement and that the City can provide us with the baseline map. $4,500 per event
5 Sampling and Analysis of Water Stations/Water System Wells Under some circumstances samples from the water system monitoring stations and water system wells must be collected and analyzed . $1,600 per event Our total estimated annual budget for providing the City of South San Francisco with support water line monitoring at the Former Oyster Point Landfill, as described above, assumes one of each of Task 1 through 4, and two events of Task 5 will need to be completed each year. This brings the annual estimated cost to: $15,300
