According to the owner, the landfill is under a corrective action
program (CAP) and has not been issued a cleanup and abatement order (CAO).
The enforcement agency (EA) has issued an area of concern (AOC) for
elevated methane detected in readings in a perimeter migration probe.
The owner addressed the AOC by clearing condensate blockages in the
landfill gas (LFG) header lines and fine-tuning the LFG collection
system. The owner indicated that the site has not received an AOC or
violation for leachate control, drainage, or erosion control-related
issues.
The owner reported that the site has received several notices to comply
(NTC) from the air quality management district (AQMD) for surface
emissions relative to air quality-related issues. The owner addressed
the NTCs by fine-tuning the LFG collection system.

The EA indicated that the landfill received an AOC in September 1998 for
destroyed portions of the eastern LFG header pipeline and two compliance
probes, due to a 500-acre wildfire along the site’s eastern perimeter
only. The EA indicated that the owner’s repairs to the LFG collection
system corrected the problem by October 1998.
The EA indicated that the owner received a violation in July 2001 for
excess methane concentrations in perimeter monitoring probe MP-12. The
owner made repairs to the LFG collection system wells and headers, and
these repairs satisfactorily addressed LFG migration by August 2001.
