Site Information per
Landfill Facility Compliance Study (Task 2)Information Source:
Owner/Operator (Orange County Integrated Waste Management Department)
Telephone conversation: March 29, 2004
E-mail response: April 21, 2004
The owner indicated that the site is currently in a corrective action
program (CAP) due to landfill gas (LFG) migration to groundwater. The owner
indicated that since additional LFG collection wells were installed, the
groundwater monitoring wells are now in compliance
The site received an area of concern (AOC) from the enforcement agency (EA)
for elevated methane readings in a perimeter migration probe. The AOC was
mitigated by installing an additional LFG collection well and relocating the
perimeter migration probe closer to the property boundary.
The owner indicated that the site has received an AOC or violation related
to erosion or drainage control issues.
The owner indicated that the site has received notices to comply (NTC) from
the air quality management district (AQMD) for surface emissions relative to
air quality. The NTCs were corrected by fine-tuning the LFG collection
system.
Information Source: Santa Ana Regional Water Quality Control Board
E-mail response: April 1, 2004
The regional water quality control board (RWQCB) indicated that the site has
been under a cease and desist order (CDO 00-44) for eroded waste slopes and
exposed refuse resulting from heavy rainstorms February 20–23, 2000. The
RWQCB indicated that refuse and sediment appeared to have been carried by
the stormwater runoff into the East Perimeter Channel. The RWQCB indicated
that the owner was advised that failure to maintain the landfill’s drainage
and erosion control systems constituted violation of waste discharge
requirements (WDR) Order No. 98-99.
The RWQCB indicated that during its March 1, 2000, follow-up inspection,
after another series of heavy rain storms, the RWQCB observed soil, refuse,
and debris in Bee Canyon Wash at the upstream stormwater monitoring point
and at the entrance to the Bee Canyon retarding basin located west of the
site. The RWQCB also indicated observing a high water mark of fine refuse
plastered to the sidewalls of a concrete trapezoidal channel located west of
the 261 Toll Road, downstream of the Bee Canyon retarding basin.
The RWQCB indicated that the owner has complied with the requirements of CDO
00-44, which included regrading the eroded waste slopes and maintenance of
the landfill’s drainage and erosion control systems. The RWQCB further
indicated that the owner continues to perform monitoring of the waste
slopes, the landfill’s drainage, and erosion control systems as required by
CDO 00-44.

Health)
E-mail responses: April 14, 2004 and April 23, 2004
The EA indicated that the owner received an AOC in February 1999 for not
replacing perimeter probes that had been buried or were missing. The EA
indicated that the owner installed replacement probes by April 1999, which
addressed the AOC.
There was a violation in June 1999 for excess methane concentrations in
perimeter monitoring probe P-1. By August 1999, the owner installed two
additional LFG collection wells that reduced the methane concentrations in
the probe to within acceptable levels.
The EA issued an AOC in April 2002 based on inadvertent damage to perimeter
monitoring probe P-2 due to Phase V-D grading activities. Additionally, the
AOC was issued because the owner/operator had ceased monitoring probes
GPB-13 and GPB-14 since February 2002 without the EA's prior knowledge and
consent. The EA indicated that the owner installed a replacement probe on
June 14, 2002, which corrected the AOC.
Information Source: South Coast Air Quality Management District
Telephone conversation: March 31, 2004
E-mail response, April 29, 2004
The SQAQMD issued an NTC for excess surface emissions relative to air
quality-related issues. The SQAQMD indicated that the owner adjusted the LFG
collection system. The site is in compliance with NTC C60050 as of November
12, 2000.
