Landfill Management
DPW Landfill Management manages the County's closed landfills and former refuse burning sites (burn sites). Although these sites no longer accept municipal solid waste (trash), continued monitoring and maintenance is required to minimize impacts to the environment and to protect public health and safety. To that end, the County regularly monitors landfill gas generation and migration, groundwater quality, and stormwater runoff quality. The County also maintains various systems at the sites to control landfill gas emissions, mitigate impacts to groundwater, and to manage the flow and discharge of storm water. On most of the sites, vegetation is used to control surface erosion. All of these activities are funded through the Solid Waste Environmental Trust Fund. The Board of Supervisors established this fund using a portion of the sale proceeds following the successful divestiture of the County Solid Waste System in 1997.
The
Landfill Management Unit works closely with local, state, and federal
regulators to maintain the sites in accordance with established laws
and regulations. These regulatory agencies include the County of San Diego Solid Waste Local Enforcement
Agency(LEA), the California Department of Resources, Recycling, and
Recovery (CalRecycle), the Regional Water Quality Control Board and the Air Pollution Control District.
In recent years, the Landfill Management Unit has sought to develop
secondary uses for the closed sites. Today, some of the County’s
former landfills and burn sites are experiencing new life as sites for
a variety of commercial developments such as recycling facilities and
automobile dealerships, as well as for recreational uses such as model
aircraft airports. 
Also,
electricity is produced at a site using the methane gas that is
naturally produced by decomposition of the waste in the landfill. This
represents a win-win situation for the County and the environment.
When considering a new use, the Landfill Management Unit works to
ensure that it is compatible with the overriding environmental laws
and regulations and that compliance can be maintained.
