Fiscal Impact/Change to Net County Cost: There is no change in Net County Cost. Through the pending Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) litigation, the County has contributed money for site investigation obtained from the County's insurance carriers which has been beneficial in development of the site closure design, and will contribute further funds for closure of the site through money from insurance carriers and Third Party Settlements. In addition, the County has received notice of award for grant funding with CalRecycle (formerly the California Integrated Waste Management Board).
Background: The County of El Dorado is undertaking the closure of the 11 acre Meyers Landfill disposal site. The Meyers Landfill operated from approximately 1947 through 1971 under a series of Forest Service Special Use Permits that were issued to private parties and the County of El Dorado. Waste disposed at the site included municipal solid waste from residential and commercial sources within the southern Lake Tahoe Basin area. The site stopped receiving waste in 1971 and in 1973 the County closed the landfill and covered the waste with an interim soil cap.
Since the closing of the site in 1973 several site investigations have been conducted. As a result of these investigations, it was determined that in the best interest of public health and safety, the site would need to be remediated. In January of 2002, the United States Forest Service (USFS) issued a Feasibility Study and Proposed Plan for remediation of the site, which was later modified and termed the Supplemental Remedial Investigation/ Feasibility Study (RI/FS). The RI/FS calls for capping the waste mass with an impermeable multi-layer cover system, installation of a passive landfill gas venting system, relocation and consolidation of a portion of the waste mass directly above a South Tahoe Public Utility District (STPUD) sewer line, and installation of a surface water collection and retention system.
Reason for Recommendation: On January 26, 2010 the Board awarded the Meyers Landfill Cap Construction Quality Assurances (CQA) Services contract to Geosyntec Consulting, Inc. This first amendment accounts for changes in the scope of work and compensation sections of the original contract. The scope of work includes required air, noise and stormwater monitoring and sampling throughout the duration of the project. This scope of work is a CERCLA requirement that was not previously identified in the current CQA contract. The environmental monitoring and sampling must be conducted as part of the Meyers Landfill closure construction project.
Action to be taken following Board approval: Upon execution by the Chair, the Board Clerks Office will forward copies of the amendment to Environmental Management for distribution, encumbrance, and administration.
