revised final closure plan - Salinas Valley Solid Waste Authority

Revised Final Closure Plan July 2010
Crazy Horse Sanitary Landfill -9- 103-97133
ECS to be decommissioned during the postclosure maintenance period will either be abandoned in
place or be dismantled and disposed of at another authorized solid waste disposal site. Well
abandonment techniques for decommissioning the groundwater monitoring system will be consistent
with the procedures prescribed in California Well Standards, Bulletin 74-90, and supplement to
Bulletin 74-81 (DWR, January 1990) or equivalent document applicable at the time of
decommissioning as required by the Monterey County Department of Health. Underground pipe
components of the leachate control system and the LFG monitoring system will be cut off at the
surface, capped, and buried to minimize the disturbance of the landfill final cover. Aboveground
components will be dismantled, decontaminated, and salvaged for reuse or discarded in a permitted,
active waste disposal site. Transportation and disposal will be consistent with federal, state, and local
laws and accomplished in a manner that prevents the introduction of leachate or waste constituents
into the environment. Materials intended for reuse may be cleaned by:
• Washing with water, detergent, or chemical solvents
• Steam-cleaning
• Scrubbing with abrasives
• Sand blasting
The residues produced as a result of cleaning reusable components will be disposed of consistent with
applicable federal, state, and local laws.
The decommissioning of each ECS is discussed further in the RFPCMP.
2.9 Security at Closed Sites
27 CCR 21790(b)(8)(A) and 21135
Entry onto the landfill during business hours is controlled by site personnel at the entrance facility,
which is the single point of public access to the site. Unauthorized access to the site will be
controlled by perimeter fencing and lockable entrance gates at the point of public access (Crazy Horse
Canyon Road). The fencing also surrounds specific on-site facilities. In 2006, groundwater
extraction wells were vandalized south of Module 1. In 2009, approximately 1,600 feet of security
fencing has been installed along the southern boundary to increase security for the groundwater
remediation system. In those areas where no fencing has been installed, topographical constraints
limit access to the site.
Security at the site is provided by the SVSWA and includes signs, written in English and Spanish,
which will be posted at all entry points 60 days before the start of final closure activities. These signs
will present (1) the intended closure date for waste disposal, and (2) the location of alternative waste
disposal sites. These signs will remain in place for at least 180 days after final waste placement. All
entry points to the site from public roads will be controlled with lockable gates. No additional
security installations are proposed for closure.
