Lopez Canyon Landfill closed in 1996, but methane gas continues to be produced from the buried trash that accumulated during 20 years of operation. 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 ft3 per day) of landfill gas.

Converting the landfill gas into reusable energy instead of being wasted by flaring has been a high priority goal of the Bureau since the early 1990’s. Following a long journey of innumerable obstacles and delays, our first gas to energy plant was built in 1999. It currently produces 6 MW and serves 4500 homes. Subsequently, we partnered with the City department of Water and Power and celebrated the completion of the nation’s largest landfill gas to energy project of its kind. We completed the installation of fifty new gas micro turbines, each the size of a refrigerator that produce a total of 1.5 MW, enough power to serve 1,500 homes. Landfill gas to energy projects such as Lopez Canyon’s is a win-win opportunity to both the City and the community. They generate cost effective renewable energy from landfill gas that is otherwise being wasted by burning, it reduces emissions of air pollutants such as methane, a potent greenhouse gas and generate income to the Bureau and the community.

The gas to energy program is widely supported by the Environmental Protection Agency, local regulators, and is very popular with the local community as well.

Because of the hard work and the innovative attitude of the City employees and our private partners and the positive support of the community, our landfill gas to energy program won an award from Solid Waste Association of North America (SWANA).

Present Use:

A section of the landfill has been dedicated for the Lopez Canyon Environmental Center, where greenwaste is collected and grinded into mulch for reuse by L.A. Residents. Refer to Free Mulch Give-Away section for more information regarding pick-up locations and hours of operation.

The new Lopez Canyon Environmental & Education Center is designed to reflect all aspects of production and use of different mulching and composting products. Construction of this Center estimated to be completed in mid-summer 2014.

Potential Future Use:

The former Lopez Canyon Landfill, a Municipal Solid Waste landfill, ceased to accept waste on July 1st, 1996, and has been in the process of closure since that date. 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.
