Site Information per
Landfill Facility Compliance Study (Task 2)Information Source: Owner/Operator:
City of Los Angeles
Telephone Conversation: March 29, 2004
The owner indicated that the site has not been required to conduct a
corrective action program (CAP) or is under a cleanup and abatement
order (CAO). The owner installed a series of micropurging pumps in the
site’s groundwater monitoring wells that render more accurate analytical
results.
The site was issued an area of concern (AOC) for landfill gas (LFG)-related
instantaneous surface emissions in a difficult-to-repair area of the
landfill. However, these “hot spots” have been repaired in a timely
manner through moisture conditioning and compacting additional soil in
the problem areas.
The site has not received AOCs or violations for surface
water-related issues.

Information Source: Enforcement Agency (City of Los Angeles
Environmental Affairs Department)
E-mail response: April 7, 2004
The enforcement agency (EA) indicated that the landfill has not
received an AOC for LFG-related issues. The owner did receive an AOC for
ponding and erosion control since the beginning of the study period
(January 1, 1998). The EA indicated that the owner promptly eliminated
the ponding and repaired the erosion in the slopes.
Information Source: South Coast Air Quality Management District
Telephone Conversation: March 31, 2004
The air quality management district (AQMD) indicated that the
landfill operator has been issued notices to comply (NTC) for LFG
surface emissions, primarily along the waste boundary. To mitigate these
emissions, the owner installed additional gas collection wells closer to
the interface between the waste and native ground. The repairs were made
in a timely manner.
