CERCLA Assessment, and Remediation System Operation and Maintenance
Location:
Chemtronics, Inc., Swannanoa, NC
Details:
Altamont provides environmental consulting services to three potentially responsible parties (PRPs) at the Chemtronics site, a geologically complex 1,100-acre EPA-lead CERCLA site in the Asheville area. The site was used for specialized manufacturing of explosives, incapacitating agents, and chemical intermediates for nearly 50 years. The site is regulated by the EPA Superfund Section (CERCLA). Historically, portions of the sight were also regulated by North Carolina Department of Environment and Natural Resources (DENR) RCRA program but all regulatory authority was recently consolidated with EPA. Altamont’s initial role was to operate and maintain two groundwater remediation systems, as well as the capped disposal areas. Since initiating work on the project, Altamont’s role has expanded to include management of all site environmental activities, regulatory negotiations, and coordination of the PRP companies. Investigation of the Chemtronics site is ongoing and interim remedial measures are underway.
The PRP companies have recently signed an Administrative Order on Consent for a full Remedial Investigation/Feasability Study. Altamont is leading the technical and administrative aspects of the RI/FS.
Site characterization and refinement of the conceptual site model have been particularly challenging at the Chemtronics site due to the complex site geology and the numerous constituents of concern. Altamont has utilized innovative investigation methods to characterize the saprolite and fractured bedrock aquifers. We have also implemented specialized maintenance procedures to improve the operation and reduce the cost of the interim corrective measures.
