Former BKK Landfill Clean-up and Abatement: Carson, California

SERVICES USED ON THIS PROJECT INCLUDE:
	Environmental Compliance		Resource Management		Planning

Sapphos Environmental, Inc. coordinated the improvements of the existing Victoria County Golf Course to enhance the quality of the golf course as well as the golfing experience. The project was designed to reconfigure the current course layout to a “links” type layout. The improvements consisted of two major components: New Irrigation System and Golf Course Renovation.

The New Irrigation System included installation of a new, centrally operated, computer controlled irrigation system encompassing the entire golf course, driving range, and practice areas. The new system addressed the facility’s common area, which includes the clubhouse and parking lot grass and planter areas, all slope areas, and all perimeter and boundary areas along public streets and adjoining public and private property.

The firm provided air quality monitoring services to the County of Los Angeles Department of Parks and Recreation at Victoria Cricket Field to ensure that the contractor met contractual obligations specified in the Victoria Cricket Field Mitigated Negative Declaration.

The Golf Course Renovation remediated problem areas of the golf course impacted by the negative effects of the former BKK landfill upon which a large part of the facilities are built. Specific components of the renovation included the following: capping (minimum of 300,000 cubic yards of soil) and re-contouring the golf course to ensure proper drainage, re-grading existing fairways and tees to include the addition of 10 to 12 inches of topsoil (70,000 to 90,000 cubic yards), rebuilding four greens, remodeling the driving range, installing concrete cart paths, re-grading and re-seeding all tees, remodeling existing bunkers and installing new bunkers, planting 30 acres of drought-tolerant native landscaping, providing new irrigation in portions of the golf course, renovating the existing methane gas monitoring system, installing methane gas collection systems and/or groundwater monitoring wells in accordance with regulatory agency requirements, and planting new trees throughout the golf course.

Sapphos Environmental, Inc. was retained by the County to provide technical oversight and project coordination for the preparation and implementation of a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and National Contingency Plan (NCP) compliant workplan to conduct a Remedial Investigation / Feasibility Study (RI/FS) to be used in the development of a Remedial Action Plan (RAP) for the former Ben K. Kazarian Landfill (BKK Landfill) that operated in the City of Carson, County of Los Angeles. Following the negotiation of appropriate risk-based clean-up goals with the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC), a Feasibility Study will be conducted to evaluate the appropriate remedial alternatives for preparation of a RAP. The RI/FS Workplan presents the site history, investigation rationale, investigation methodology, and quality assurance plan for the investigation of the potential effects of hazardous materials that may be present in the landfill soil cover, native soil beneath the landfill, and groundwater. The remedial investigation also will investigate and characterize the waste materials, leachate, and both the on-site and off-site occurrence of landfill gas. The analytical data obtained through the sampling program will be used to develop risk-based clean-up goals that protect human health and the environment by completing health risk assessments.

In relation to the RI/FS, Sapphos Environmental, Inc. also provided the County with environmental risk information in support of Potentially Responsible Party (PRP) investigations to facilitate the efficient use of County resources. Identification of PRPs is a critical step in minimizing the County’s potential liability in relation to implementing remedial actions should such actions be determined to be necessary as a result of the environmental risk investigations and the RI/FS.
