Miramar Landfill & Greenery



NOTE: Effective January 1, 2022, Miramar Landfill Will Not Accept Treated Wood Waste for Disposal 


INCLEMENT WEATHER: During rain or other weather-related conditions, the landfill and greenery operations reserves the right to temporarily close to vehicles with trailers for safety reasons. This would occur in the event conditions at the tipping deck are not conducive to the maneuvering of vehicles with trailers. It is a safety issue to the public and employees and a hindrance to operations when dealing with incapacitated vehicles.

Treated Wood Waste Disposal

Effective January 1, 2021, the City of San Diego will no longer accept treated wood at the Miramar Landfill. California regulations for treated wood waste disposal will expire and treated wood waste will now be regulated as hazardous waste. Chemicals such as arsenic, chromium, copper, creosote, and pentachlorophenol used in chemically treated wood pose a risk to human health and the environment. Examples of treated wood include docks, decking, fence posts, guardrails, piers, pilings, landscape timbers, railroad ties, sill plates, and utility poles.

The Miramar Landfill is a Class III solid waste landfill and is prohibited from accepting hazardous waste. Loads containing any treated wood cannot be accepted for disposal and will be rejected at the scales. Treated wood waste must be transported by a registered hazardous waste transporter and disposed of at a Class I hazardous waste landfill.

Businesses and residents that generate treated wood waste from a location within San Diego city limits may provide a written waste determination stating the treated wood waste is not hazardous or designated waste in accordance with the PDF icon Miramar Landfill Acceptance Criteria for the Disposal of Treated Wood Waste. Treated wood that has been determined not to be hazardous waste or designated waste may be accepted at the Miramar Landfill for disposal as a special waste pending written approval and advanced scheduling.
