The owner is not aware of the site being placed under a corrective
action program (CAP) or issued a water-related clean-up and abatement
Order (CAO) since development of the database (January 1, 1998). The
owner has been directed to prepare an evaluation monitoring program (EMP),
which has been submitted to the regional water control board (RWQCB) for
review/approval, but no decision has been made. There have been no
problems implementing existing groundwater related regulations at this
site. The owner’s consultant intends to negotiate with the RWQCB to
reduce efforts and cost associated with this site over the next three
years. However, the owner indicated that budget constraints, due to the
internal system of revenue generation, have limited activity at the
site.
Regarding landfill gas, the owner is not aware of receiving any
violations from the enforcement agency (EA). No additional gas-related
protection measures have been implemented at this site beyond regulatory
minimums. Quarterly monitoring of gas probes is ongoing, and the owner
does not have any issues with current regulations.
There have been no leachate control issues at the site. Holtville is
located in an arid desert region that annually averages 3 inches of
precipitation per year. The site generates little or no leachate. At one
point several years ago, the site had operational drainage ponding in a
localized area, but this was addressed with minor grading. There are no
surface water features adjacent or nearby the landfill. No drainage,
erosion control, or surface water protection measures have been
implemented beyond regulatory minimums. There have been no problems
implementing the existing regulations at this site.
The only air quality measures taken at the site are periodic watering of
roads and the operations area to control dust in accordance with the
plan established by the air pollution control district (APCD). The
facility has not received any notices to comply (NTC) or notices of
violation (NOV) from the APCD. No additional protection measures are
being implemented, and there have been no problems implementing existing
air quality regulations at this site.

A CAO is being drafted for a groundwater release of volatile organic
compounds (VOC) 1,1 Dichloroethane and chloroform, which occurred in
2002. The owner submitted an EMP work plan pursuant to Title 27
regulations on October 25, 2002, after performing a discrete retest to
confirm the release.

The site is a “trickling waste”† facility located on the fringe of four
different populated areas. At one time this site was a convenient
disposal location for people before the area began to grow. These types
of “trickling waste” sites are typically down to accepting 3 to 15 tons
of waste per day. Local hauling and curbside pickup has significantly
reduced the volume going to the site. The interviewee indicated that
today a transfer station to serve the communities probably makes more
sense than operating a local MSW landfill.
Average rainfall in the area is about 3 to 3.5 inches per year, and
occurs in 3 or 4 events per year. The area has a very high evaporation
rate.
The interviewee stated that the owner has indicated satisfaction with
the waste discharge requirement (WDR) and reporting requirements. The
interviewee has no issues with the existing regulatory requirements.
Although landfill gas monitoring at the surface has not detected
landfill gas, recent groundwater retesting at the Holtville Disposal
Site reflects an increase in VOCs. The continued occurrences of VOCs in
groundwater may be attributed to lateral migration of landfill gas. The
RWQCB is currently evaluating this issue.

There have not been any notices to comply or notices of violation issued
to the Holtville Disposal Site. This landfill has no facility for the
destruction of landfill gases. The existing regulations do not require
the destruction of methane, which is a greenhouse gas.
†As
defined in the Title 27, California Code of Regulations, a site is
considered a trickling waste site “if the average annual waste disposal rate
… is reduced for two consecutive years to a rate equal to or less than 30
percent of the average annual tonnage rate during the previous 10 years
(exclusive of the minimum and maximum tonnage years)” (section 21110
[b][2]). By this definition, the CIWMB has considered this site to be a
“trickling waste” site.
