The site accepts such waste as segregated asphalt, municipal solid and inert waste, clean dirt, manure, segregated uncontaminated green waste, scrap tires, and construction/demolition and industrial material.[3][2]
Regional access to the landfill is from the Ventura Freeway (State Route 134) at the Figueroa Street exit. Public access is only from Scholl Canyon Road.
Capacity
As of December 2011, the site contained 314 acres (127 ha) of waste out of a total permitted 440 acres. This landfill is allowed to receive 3,400 tons per day.[6]
It has a remaining capacity of 9,900,000 cubic yards (7,600,000 m3). Its estimated closure date is 2030.[6]
Power generation
In 1994, a 5 mi (8.0 km) pipeline was completed that transports methane gas produced at Scholl Canyon Landfill to the steam boilers at the city's Grayson Power Plant. Since 1994, three Grayson Units have generated power using this methane blended with natural gas. During 2012, the Plant generated approximately 80,000 MWh from Scholl Canyon landfill gas, providing 7% of Glendale’s energy needs.[4]
Projects
Bidding took place in July 2015 for geotechnical slope repair at the landfill, with Los Angeles Engineering, Inc. awarded the contract.[7][8]
Proposed expansion
The City of Glendale established its Zero Waste Policy in 2010, including to operating a clean, high-tech, and integrated waste management system, needing expansion of the landfill.[9][10] In 2014, The City of Glendale issued a Draft Environmental Impact Report (EIR) to address potential impacts from implementation of the proposed Scholl Canyon Landfill Expansion project. The Draft EIR (DEIR) was circulated for a 60-day review/comment period from April to July 2014.[11][12][13][14] It is for the landfill to transition to a conversion technology facility. Technologies such as gasification, pyrolysis, and plasma arc are being considered.[4]
At an October 2015 public meeting on the proposed expansion project and DEIR, the city stated it "has no immediate plans to proceed with any expansion and possibly may not for quite some time, if ever, depending on the success of the City’s aggressive waste management alternatives."[15][16]
Golf course and tennis courts
The Scholl Canyon Golf and Tennis Club was built in 1993, by the American Golf Corp. based in Santa Monica. The 56 acres (23 ha) project was constructed on top of the northwest part of the landfill in the San Rafael Hills. This layout replaced a golf facility that was closed in 1989 after dangerous levels of methane were released from under the golf course.[17]
