Providing comprehensive landfill OM&M services in San Diego County, CA, for over 40 years.
SCS Engineers and field technicians support San Diego County with a comprehensive range of engineering and contracting services, including landfill gas to energy (LFGE) systems; operations, monitoring, and maintenance (OM&M); air quality, regulatory compliance, and greenhouse gas support services for the county’s ten landfills.
SCS has provided consistent and comprehensive value to the Bell Jr. High, Bonsall, Encinitas, Gillespie, Hillsborough, Jamacha, Palomar Airport, Poway, San Marcos, and Valley Center landfills since the ’80s. Our teams perform routine & non-routine OM&M and construction services, including blower-flare maintenance, at all sites.
SCS tasks consist of performing a wide range of regulatory compliance services, including:
In 2014 – 2015, at San Marcos, we installed dual-contained sumps and a new LFG condensate injection system skid.
In 2018, at Palomar Airport, we coordinated with the Federal Aviation Authority (FAA) to complete installation of LFG extraction wells to control gas migration better.
At Hillsborough Landfill, which is surrounded by a residential condominium community, SCS designed and provided construction oversight for landfill closure activities. SCS also designed, constructed, and currently operates a replacement blower-flare system.
At Hillsborough and Bell Jr. Landfills, SCS replaced older oversized flares with micro-flares in 2017. SCS designed, permitted, constructed, and currently operates the micro flares, which accommodate the low volume and quality of LFG at each landfill (as low as 40 scfm @18% methane).
At Paradise Valley/Bell Jr. High Landfill, which is located adjacent to a school facility and is surrounded by a residential condominium community, SCS designed, constructed and currently operates a replacement blower-flare system.
At San Marcos Landfill, SCS provided expert witness services related to lawsuits against the landfill. SCS successfully obtained a San Diego County Air Pollution Control District (SDAPCD) Rule 59 variance, designed a new LFG system, prepared a Title V air permit, and has provided ongoing air quality permitting support.
At Encinitas and Gillespie Landfills, SCS designed and installed gas migration control facilities.
At Jamacha Landfill, SCS is currently working on the design and construction of a replacement blower-flare system.
For all County landfills, SCS completes annual emissions inventories; air permitting and compliance for landfills and landfill equipment; Title V, NSPS, and NESHAPs periodic compliance reports; evaluation of applicability and compliance with AB32; SDCAPCD operating permit variance applications, higher operating value requests, and alternative remedy/timeline requests for surface emissions exceedances; evaluation of applicability and compliance with the EPA GHG mandatory reporting rule, including development of monitoring plans; and air, GHG, and LFG advocacy with various air districts, CARB, and CalRecycle.
