SDC, with our partner Philotechnics, provide identification, removal, remediation, processing and disposal of low-level radioactive waste (LLRW) including mixed and hazardous waste at facilities throughout the world for the Army Joint Munitions Command based out of Rock Island, IL. At Rock Island alone, SDC inspected, inventoried and packaged 9652 radiological items at the MCF to meet Waste Acceptance Criteria at 3 different T&D facilities, manifested and shipped either to SDC Philo LLRW processing facility or directly to a land disposal facility and provided certificates of disposal showing final lawful disposal. Similar projects have been completed at 10 other CONUS sites, with work on-going at other sites.

SDC performed environmental soil investigations and characterization for  NOAA facility in Micronesia and currently provides scientific and technical staff augmentation support to NOAA’s National Weather Service (NWS) Office of Facilities, Facilities Management Division (OF2).  This contract provides direct project architecture/engineering (A/E) and safety technical support services for NWS OF2 in Silver Spring, Maryland. 

SDC has been providing (since 2018) through the USACE Baltimore District: environmental compliance; hazardous waste management support and disposal; regulated pharmaceutical disposal; EPCRA Tier II § 312 and TRI § 313 Reporting; pollution prevention consulting, and spill response for Joint Base Myer-Henderson Hall (JBM-HH) in Arlington, Virginia and Fort McNair in Washington, DC. SDC ensured all waste profiles were accurate and manifests are acceptable to treatment storage and disposal facilities (TSDFs). SDC assisted with preparing biennial data to support facility hazardous waste RCRA reporting required by the Virginia Department of Environmental Quality (VADEQ), and District of Columbia’s Department of Energy and Environment (DOEE).

SDC completed a comprehensive asbestos survey of all the buildings, including research facilities, hangers, storage facilities and office spaces at all three campuses of the Patuxent River Naval Air Station. This involved preparing a detailed sampling plan, conducting the inspections, analyzing the samples and preparing a database to document all of the asbestos at the facility for future abatement purposes.

SDC has provided radiological and hazardous materials investigation, characterization and removal actions associated with radioactive materials from medical and industrial sources as well as a variety of hazardous wastes in four of the Gateway National Parks in New York. This has included full CERCLA investigations and development of remedial action plans and has included providing public meeting support for stakeholder meetings throughout the process.

NS Savannah was the first nuclear-powered merchant ship. She was built in the late 1950s as a demonstration project for the potential use of nuclear energy. SDC is providing general engineering, radiological and technical services for field inspections and oversight of physical work activities and specialized engineering and analytical services to perform independent review of regulatory compliance documents associated with decommissioning of the N.S. Savannah nuclear power plant. Compliance analysis includes the following federal statutes: NEPA, TSCA, RCRA, CWA, OSHA, and NHPA. Work includes support of maintaining the historical artifacts and records of this unique ship.

Per- and polyfluoroalkyl substances (PFAS) used in consumer and industrial manufacturing are persistent in the environment. Aqueous Film Forming Foam (AFFF) is one form of PFAS and has been used for fire fighting for numerous applications. SDC has completed multiple projects to remediate and remove AFFF. Work includes inventory of waste on-site, waste characterization, packaging of waste, disposal of waste, clean-up of waste releases, extraction of AFFF from fire protection systems, cleaning/rinsing of AFFF equipment, and proper disposal of AFFF concentrates.
