Fishbeck has provided consulting and design services for the Reynolds’ Red Bluff facility for nearly 20 years. The associated landfill is no longer operating; however, the landfill had historically received polychlorinated biphenyl (PCB) and heavy metal containing wastes. As an unlined landfill, the landfill leachate communicates directly with site groundwater, an issue is further complicated by the presence of an agricultural water supply dam adjacent to the site on the Sacramento River, an identified sensitive fish habitat.
Fishbeck’s work was instrumental in developing a clear understanding of the site’s hydrogeologic dynamics which demonstrated that the leachate impact was minimal. This work also facilitated remediation of a portion of the landfill and sale of the property to the United States Bureau of Reclamation for redevelopment of their irrigation system and restoration of critical fish habitat.
Fishbeck’s responsibilities include project oversight in the operation, maintenance, and management of the landfill, including emergency repairs, compliance reporting, National Pollutant Discharge Elimination System (NPDES) application and assistance, design, implementation and reporting for NPDES mandated studies, minor financial predictions, engineering and design for the on-site wastewater treatment system. Fishbeck also conducts routine reporting of groundwater and leachate sampling results, as well as development of the State of California required Preliminary Closure and Post-Closure Maintenance Plan including annual financial assurance reporting.
Fishbeck provides as-needed special project work for the landfill. These projects have included design and development of bid specifications for transferring waste from the sites settling basins to the landfill, preliminary and final cap design services, capacity assessment and waste management planning, testing for methane generation within and adjacent to the landfill, development of post-closure methane management plans, design, implementation and reporting for a one year temperature study of the Sacramento River adjacent to the site, and management of the Site’s NPDES permit. Fishbeck has provided specialized services, including securing US Fish and Wildlife valley elderberry longhorn beetle (an identified threatened species) credits from a conservation bank to compensate for habitat loss and removal of rattle snakes to allow for safe survey of waste deposition areas.
Fishbeck’s work has resulted in a reduction in the landfill footprint, improved stormwater management, and development of a coordinated cost-effective approach for management of waste deposition.
