To control landfill gas emissions and migration off the landfill property and comply with SCAQMD rules and regulations, in 1989, we installed an active gas collection system at the landfill. The gas collection system at Lopez Canyon consists of 450 gas collection wells, several miles of gas collection header line and 7 landfill gas flares. Currently, Lopez Canyon generates an average of 3,400 cubic feet per minute (cfm), (5,000,000 cubic feet per day) of landfill gas.

SRR Report - May 31, 2013
A section of the landfill has been dedicated for the Lopez Canyon Environmental Center, where greenwaste is collected and ground into mulch for reuse by L.A. Residents. Refer to Free Mulch - Two Options section for more information regarding pick-up locations and hours of operation.
The new Lopez Canyon Environmental and Education Center is designed to reflect all aspects of production and use of different mulching and composting products. Construction of this Center was completed in March 2015.
Events Calendar
The former Lopez Canyon Landfill, a Municipal Solid Waste landfill, ceased to accept waste on July 1st, 1996, and final landfill closure has been completed as of September 2012. While the landfill is zoned 'Open Space' and is ultimately destined to become a community recreation area, state law mandates that a monitoring period of at least thirty years be conducted, during which unsupervised public use of the site must be prohibited. The purpose of this monitoring period is to ensure that gas and liquid (leachate) production by decomposing organic matter is measured and safely disposed of in ways that ensure it will not contaminate groundwater under the site. At the end of this period, if gas and leachate production and subsidence of the site's ground surface have fallen to minimal levels, public recreation and other uses consistent with a zoning designation of 'Open Space' may be initiated.
