NOP - Notice of Preparation of a Draft EIR
Present Land Use
The Landfill has been inactive since 1997. Since that time, activity has been limited to site monitoring and maintenance. The City of San Marcos has assigned a "Solid Waste Management Area" (SWM) General Plan and Zoning Designation.
Document Description
The project consists of implementing the Final Closure and Post-Closure Maintenance Plans for the San Marcos Landfill ("Landfill") using a monolithic soil cover system or other similar system as required by regulatory authorities. The soil cover will range in depth from five (5) feet to eight (8) feet. The project will require the importation of approximately 480,000 cubic yards of soil over an approximate 8-month period. The imported soil will be mixed with approximately 120,000 cubic yards of on-site soil and placed over the Landfill surfaces. Closure of the Landfill will be in accordance with requirements from Title 27 of the California Code of Regulations. The Final Closure and Post-Closure Maintenance Plans will require approvals from the County San Diego Board of Supervisors, California Integrated Waste Management Board (CIWMB), San Diego Regional Water Quality Control Board (RWQCB), San Diego Air Pollution Control District (APCD), and County of San Diego Department of Environmental Health, Local Enforcement Agency (LEA).
