Rocky Flats Environmental Technology Site Support

Rocky Flats Environmental Technology Site SupportWREG personnel provided Kaiser-Hill Company and the US Department of Energy (DOE) air compliance, monitoring, and research support for the Rocky Flats Environmental Technology Site (RFETS) from 1996-2006. One of WREG’s Principals managed the air quality management organization at RFETS from 1996 to 2000 and continued to support Kaiser-Hill and DOE as the air quality Subject Matter Expert for the site, pending completion of regulatory closure requirements, including Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) requirements.

RFETS was a nuclear weapons production facility established in the early 1950s. The site was decommissioned and cleaned up, with physical completion declared in October 2005. Air compliance issues were challenging, given that the facility and its operations were constantly changing. Support activities included project-by-project regulatory review, emission estimation, compliance auditing, and permit application preparation and negotiation. The site was also subject to the radionuclide National Emission Standards for Hazardous Air Pollutants (NESHAP). Dispersion modeling analyses performed by WREG personnel aided in planning appropriate control measures for remediation and decommissioning projects.

Air monitoring included the acquisition of meteorological data from an on-site tower, continuous ambient monitoring at nearly 40 locations for radioparticulates, and effluent (in-stack) monitoring for particulate and gaseous radionuclides. Monitoring results were analyzed and reported to both regulatory agencies and the general public.

WREG team members also worked with RFETS personnel to research the movement of radionuclide contamination through the air pathway during a five-year actinide migration study. WREG personnel have co-authored several papers based on this research.
