Chemical Processing Facility Decontamination
Los Angeles, CA
Amount: $1.3 M

Background: This confidential commercial client has a chemical processing facility which was situated on a 7.09 acre parcel located outside Los Angeles, California. The site was in operation for over 75 years and manufactured clay absorbents for the petroleum refining industry including hydro-desulfurization catalysts, and Fenuron and Tordon mixtures. Several mixtures contained naturally occurring radioactive materials (NORM) with measurable concentrations of thorium and uranium. In the course of manufacturing, various areas within 16 structures comprised of approximately 89,500 SF were contaminated with radioactive materials. Facilities included office and laboratory areas, processing equipment, tanks, and storage warehouses.

Scope of Work:

Major elements of the project completed by Solutient Technologies included:

• Project was accomplished under several discrete tasks including: radiological decommissioning and decontamination of above grade structures, asbestos abatement, demolition of above grade equipment, structures and materials, radiological decommissioning and decontamination of below grade affected structures and soils, demolition of below grade unaffected structures, utilities and materials, soil remediation, and site restoration.
• Performed all site activities under Solutient Technologies' California Radioactive Materials License and in accordance with NUREG 1575 the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). All plans and permits were approved by the state, county and/or city regulatory authorities.
• Set up and operated an on-site laboratory for alpha, gamma and fluorometry analysis of soil samples, and gross alpha and beta analysis of wipe samples. The laboratory delivered real-time results to the Solutient site supervisor during the characterization and remediation activities.
• Developed the Site Radiological Health and Safety Plan, Decommissioning and Decontamination Plan, conducted all necessary training, instituted the site radiological health and safety program, and provided the laboratory technical, and quality assurance procedures.
• Conducted remediation and management of all radioactive materials, operation of the on-site radiological analysis laboratory, waste disposal activities associated with hazardous and radioactive waste, demolition support, and health and safety management

Solutient successfully performed radiological remediation activities at the site concurrently with facility demolition and other non-radiological chemical remediation activities. The final site assessment was approved by the California Radiologic Health Branch and the site was a free released for unrestricted industrial use.
