CEQA/NEPA Analyses

CEQA Air Quality Analysis and Toxics Risk Assessment, Proposed Expansion to Fink Road Landfill, Stanislaus County, CA. As part of an EIR for a proposed expansion to the Fink Road Landfill in Stanislaus County, CA, SCS completed an air toxics risk assessment, which evaluated potential human health impacts due to current and future exposures from the project. The risk assessment was part of a larger air quality analysis completed for the expansion EIR. The analysis included an evaluation of health risk due to diesel exhaust from heavy equipment and refuse hauling vehicles at the landfill. As part of this project, SCS also researched the conversion of refuse hauling fleets to alternative fuels in order to generate emission reduction credits (ERCs) for CEQA mitigation measures.

CEQA Air Quality Analysis and Toxics Risk Assessment, Salinas Valley Solid Waste Authority Landfill, Monterey County, CA. SCS completed air quality and risk assessment sections of a large EIR being prepared for long-term refuse collection and disposal options for the Salinas Valley Solid Waste Authority’s Regional Landfill Project. The project included three landfills and 10 transfer stations, which were combined into four different project scenarios. The project included emissions estimates, air dispersion modeling, and risk calculations. The analysis included an evaluation of health risks due to diesel exhaust from heavy equipment and refuse hauling vehicles at the landfills and transfer stations, which were part of the project.

CEQA Mitigation Measures Development and Implementation, El Sobrante Landfill, Corona, CA. SCS was enlisted to develop a series of mitigation measures for fugitive dust emissions from landfill construction and operations at the El Sobrante Landfill in Corona, CA. SCS also developed an implementation plan for the CEQA Mitigation Monitoring and Reporting Program (MMRP), which was required as part of the approval of the EIR. SCS completed ambient monitoring for particulate matter of less than 10 microns (PM10) levels, and worked with the SCAQMD to develop a long-term strategy to reduce dust emissions.

Landfill Risk Assessment, Closure and Post-Closure Development, BKK Landfill, West Covina, CA. As part of an EIR for proposed closure and post-closure development of the Class III portion of the BKK Landfill, SCS completed a risk assessment that evaluated the potential human health impacts due to current and future exposures to contaminants in LFG and other environmental media. The risk assessment was part of a larger air quality analysis completed for the EIR. Through reasonable risk estimates, SCS was able to demonstrate that the proposed development of the landfill (i.e., golf course and Business Park) could occur without causing adverse health effects above CEQA significance levels.

CEQA Air Quality/GHG Analyses and Toxics Risk Assessments and Air Permitting, Proposed Landfill Expansions. Projects included expansions to the Newby Island, Forward, Crazy Horse, Johnson Canyon, Jolon, Fairmead, Keller Canyon, Redwood, Altamont, and various other landfills.

This closed landfill site is currently occupied by two golf courses and other commercial and residential developments being considered for additional redevelopment. The landfill may have received hazardous and non-hazardous wastes. Project work at this facility has included completion of soil vapor surveys, installation and monitoring of LFG migration probes, LFG sampling/analysis, oversight of cover and subsurface soil and groundwater sampling, completion of a human health risk assessment, CEQA assistance, and negotiations with regulatory agencies. The site is currently being considered for listing on the National Priorities List (NPL) as a potential Superfund site. Oversight of the landfill is provided by the U.S. Environmental Protection Agency (EPA) Region IX, Department of Toxic Substance Control (DTSC), and the Los Angeles County landfill local enforcement agency (LEA).

LFG Assessment, Cover Maintenance, and Monitoring, Cogen Kramer Landfill, Los Angeles, CA. The site is located adjacent to residential development and is partly occupied by two closed County correctional facilities. Project tasks have included LFG assessment, installation of LFG migration probes, emergency cover repair and ongoing cover maintenance, preparation of an LFG and cover assessment work plan, and regulatory liaison with the Los Angeles County LEA, Cal Recycle, and the South Coast AQMD. In addition, methane monitoring is conducted at one of the closed jail facilities (related to TV and movie productions).

Environmental Monitoring and Postclosure Care, Cal-Compact Landfill, Carson, CA. The site is a former hazardous waste landfill that is being considered for redevelopment. The site is currently under the oversight of the DTSC. Project tasks have included LFG assessment, LFG engineering, design of methane protection systems, and development of an LFG monitoring program. Mr. Sullivan also oversaw the completion of post-closure care services at the site, including LFG monitoring, LFG system O&M, groundwater sampling and analysis, cover maintenance and repair, site security, storm water sampling/analysis and inspections, and regulatory liaison.

LFG Assessment, Cover Maintenance, and Monitoring, Lane Road Disposal Site, Irvine, CA. The site is located adjacent to residential development and has been redeveloped into a golf course.

Burn Dump Investigation in San Joaquin County, CA. As part of this project, Mr. Sullivan provided technical oversight for investigations of a burn dump site, which included soil investigations, trenching investigations to determine the extent of refuse, LFG migration assessment, waste sampling/analysis, hazardous waste determination, and other project tasks. The project site was slated for residential redevelopment; therefore, all project elements were completed in consideration of this type of redevelopment.

Investigation, Risk Assessment, and Remediation, Kaiser Ventures Inc. Facilities, Fontana, CA. For the former Kaiser Steel plant in Fontana, Remedial Investigation (RIs)/ Feasibility Studies (FSs), Remedial Action Plans (RAPs), and Remedial Designs were prepared for three on-site operable units under DTSC’s oversight. Mr. Sullivan was responsible for a number of individual soil, groundwater, surface water, and waste investigations at the Kaiser site, including treatability studies, risk assessments, RAPs, and hydrogeological studies, storm water pollution prevention plans, and spill prevention, control, and countermeasure (SPCC) plans. These projects included investigations of two landfill sites, with both hazardous and non-hazardous wastes, including soil, waste materials, hazardous waste, groundwater, and surface water issues. The site was redeveloped into the California Speedway, a NASCAR race track.

Investigation, Risk Assessment, and Remediation Feasibility Study, Mission Bay Landfill, San Diego, CA. For this site, Mr. Sullivan managed a significant forensic investigation and site assessment of the former landfill site, which is located next to a river, bay, and amusement park, and is used heavily for recreational purposes. This work has included investigations of the extent of refuse, cover thickness, LFG composition and migration, soil, surface water, groundwater, and other environmental media associated with Mission Bay. The field investigations were followed by a risk assessment, and given the highly visible and public nature of the landfill project, focus on risk communication was of primary importance. Ultimately, several candidate risk-based remediation methods applicable to the site will be identified with typical costs associated with each method. This project included interface with the San Diego County APCD, RWQCB, LEA, and DTSC.

Landfill Engineering, LFG Migration Assistance, and Human Health Risk Assessment, Geer Road Landfill, Modesto, CA. Management of a variety of projects, including closure design and CQA services, cover repair, LFG engineering, air quality compliance, human health risk assessment, LFG system O&M, and LFG and groundwater monitoring.
