E-mail response, March 15, 2004
No environmental compliance issues have occurred at this site since
the beginning of the study period (January 1, 1998). No additional
environmental protection measures have been implemented beyond the
regulatory minimums. There are no known environmental protection
regulations that have been overly difficult, costly, or confusing to
implement at this site.

This site was closed using a thick-soil engineered alternative cover
system. While there have been no groundwater-related actions since the
beginning of the study period (January 1, 1998), contaminants have been
detected in nearby groundwater monitoring wells.
There have been no problems implementing the existing landfill
regulations for the protection of groundwater at this site. However,
although the performance standards for engineered alternative covers are
spelled out in Title 27 of the California Code of Regulations, the
interviewee questions whether these alternatives are able to
sufficiently protect the environment.

This landfill is not required to have permits with the MDAQMD. The
agency is not aware of any air quality issues related to this site.
Because the site has been closed for a number of years, the MDAQMD has
limited information about it.
The area around the Baker Refuse Disposal Site is very arid. The U.S.
Environmental Protection Agency defines an arid area as an area
receiving less than 25 inches of rainfall per year. This area receives
only about 4 or 5 inches of rainfall per year. A direct relationship
exists between the wetness of a landfill and the amount of landfill gas
generated. Because of the arid conditions around this landfill, this
landfill generates very little gas.
