Closure Plans for Contaminated Sites and Regulatory Closure Negotiations
Closure plans are prepared to supplement work plans for contaminated sites when a property owner is interested in obtaining No Further Action letters from the lead regulatory agency. Closure plans provide a description of administrative and technical requirements and factors supporting closure, including cleanup goals based on indoor vapor intrusion pathways and groundwater intrusion pathways. Communicating closure strategy is effective for early regulatory approval.

Site Closure Plan and Closure Strategy and Regulatory Support, Former Aerospace Site, Southern California
A soil vapor extraction system located at former aerospace site in Southern California had operated for a number of years. The client requested a strategy to obtain regulatory site closure. In response, a site closure plan was prepared outlining a schedule and a list of technical and administrative requirements to support site closure. The closure plan also listed methods and procedures to demonstrate that site-specific cleanup concentrations were protective of human health and groundwater.

Treatment of Groundwater Impacted with 1,4-Dioxane, Westlake Village, California
The development plan for a former media manufacturing site impacted with volatile organic compounds (VOCs) and 1,4-Dioxane in groundwater included the construction of a large development in Westlake Village California. A feasibility study concluded that a pump-and treat system consisting of an advanced oxidation process combined with liquid phase activated carbon (LPGAC) was required. The follow-up work included preparing a detailed design, preparing NPDES permits for storm water discharge, process flow diagrams, layout diagrams, and process and instrumentation diagrams.
