Executive Summary:
The Department of Public Infrastructure (SPI) is recommending the approval of an agreement with EBA Engineering to provide water quality and landfill gas monitoring services at the three former rural landfills commonly known as the Annapolis, Guerneville and Occidental Landfills, in an amount not to exceed $228,360 for Fiscal Year 2024-25, and $201,740 annually for subsequent years, for three (3) years with two (2) optional one-year extensions. The contract will provide for water monitoring services at the three locations budgeted at a total of $73,980 per year, and miscellaneous costs for items such as retests, annual review, consultations, emergency services, expert testimony, and other additional services for unanticipated gas and water monitoring estimated at $154,380 for the first year of the contract, and $127,760 per subsequent year.
Discussion:
The County has contracted to perform water quality and landfill gas monitoring services since 1995 as regulatory requirements for monitoring and reporting have significantly increased, and SPI does not have staff with the expertise to meet these requirements. Both federal and state regulations require that owners of closed landfills must monitor water quality and landfill gas and report monitoring results, to safeguard the health and welfare of the public and the environment. California Code of Regulations Title 27 (CCR Title 27) and site-specific Waste Discharge Requirements (WDRs) issued by the Regional Water Quality Control Board set the regulatory standard for required environmental monitoring and reporting at these sites to ensure facilities are maintained in a manner protective of people and the environment during post closure. The County faces substantial legal penalties for failure to collect and report environmental monitoring data from the County closed landfill sites. The prior Agreement for these services expires September 24, 2024, for a total of $117,044 per year.
On May 22, 2024, SPI issued a request for proposals for water and landfill gas monitoring services for the closed rural landfills. One proposal was received, reviewed, and scored according to qualifications and quality. Upon completion of this review, EBA Engineering (EBA) was selected based on their technical qualifications and proposed costs.
EBA is a local California corporation and a certified small business enterprise, with more than 39 years of experience in the solid waste environmental field and their proposal demonstrated a level of capability and service that will allow them to perform the work in a manner that will meet the County's regulatory needs. SPI has worked with EBA for many years on several different environmental projects, including water and gas monitoring at the County's three closed rural landfills, and is satisfied with the high level of expertise and work performed.
The proposed Agreement will provide for EBA to perform all work necessary for gas, water and leachate monitoring at the Annapolis, Guerneville, and Occidental closed landfills. In addition to monitoring services, the Agreement will provide response services for any emergency at the request of SPI.
SPI requests approval and authorization for the Chair to sign an Agreement for Professional Services with EBA in the amount of $228,360 for Fiscal Year 2024-25, and $201,740 annually for each subsequent year for a three-year period with (2) two optional one-year extensions, to provide water quality and landfill gas monitoring services, and emergency services at the former rural landfills.
