Site Information per
Landfill Facility Compliance Study (Task 2)Information Source: Owner/Operator (Riverside County Waste Management
Department)
E-mail responses: April 5, 2004 and April 16, 2004
The site is currently in an evaluation monitoring program (EMP) but will
soon be in a corrective action program (CAP). The owner is currently
implementing corrective action measures, including operation of a
landfill gas (LFG) collection system that has been reducing volatile
organic compound (VOC) concentrations in site groundwater monitoring
wells.
The site has not received an area of concern (AOC) or violations for LFG-related
issues from the enforcement agency (EA).
The EA issued a violation in September 2002 for erosion control issues
at the site. To repair the problem, the owner filled in erosion rills
and re-graded areas where ponding had occurred. The owner repaired the
problems to the satisfaction of the regional water quality control board
(RWQCB). During the October 2001 inspection, the EA commented on
leachate observed on the surface of the rocks at a catch basin. This was
investigated and was found not to be leachate. Rather, it was runoff
from green waste that discolored the surface water, which was not a
violation.
The owner has not received a notice to comply (NTC) or notice of
violation (NOV) for violations of LFG-related or general air
quality-related regulatory requirements from the air quality management
district (AQMD).

The landfill is in an EMP, and the operator is currently operating a
landfill gas extraction system as part of mitigation for groundwater and
LFG impacts. In addition, RWQCB staff approved a groundwater
pump-and-treat system for the site to further mitigate for groundwater
impacts beneath the landfill and off-site. The groundwater
pump-and-treat system is not operational at this time; the system is
scheduled to go online in mid-2005.

for leachate control in October 2001 and an AOC for erosion control
issues in September 2002.
Information Source: South Coast Air Quality Management District
Telephone conversation: March 31, 2004
The air quality management district (AQMD) indicated that the landfill
owner has not been issued an NTC or NOV for gas migration issues or
general air quality issues, and that the site is in compliance with air
quality and LFG control requirements.
