  • Needs Analysis and Scoping

    Key to identifying the goals and scope of a decommissioning project are consideration of physical quantities, boundaries, the historical use, and the nature and extent of impact from past operations including all available data. Additionally, the intended future use, applicable regulations, budget and funding, stakeholders’ rights and responsibility also play vital roles in process management.

  • Risk Assessment

    Examination in this phase of the types of potential RCRA hazardous substances will be carefully designed for areas that may be contaminated, along with methods to identify such substances, for the purpose of decontamination and possibly disposal. The most important goal will be methods and means for documentation of the effort. Historical data and future use will form the basis for determining acceptable criteria for the free release of the facility for unrestricted use by future occupants or for demolition/renovation.


  • Surveys

    Surveys can be conducted for radioactive materials, asbestos containing materials, lead paint, or PCB’s.

  • HazMat Material Moves

    Chemical, biological, and radioactive raw materials, R&D intermediate compounds, and contaminated equipment can be moved to a new facility or managed for proper disposal.

  • Decontamination

    Based on the nature and extent of Chem/Bio/Rad contamination selected methods for decontamination will used to reduce or eliminate contaminants in order to achieve selected release criteria. If decontamination is impractical or unsuccessful then hazmat demolition practices can be opted for.

  • Confirmation Sampling

    Confirmation sampling/surveys can provide data to support conclusions that the site meets the established release criteria for the contaminants in question. Sampling methods and analytical protocols must support data quality objectives.

Investigation Report

  • Report of Findings

    A final report is prepared documenting the entire process from the review of historical information through the development of release criteria and presents conclusions based on confirmation survey and testing data. For radioactive materials licensees this process is done in accordance with the Multi-Agency Site Survey and Investigation Manual (MARRSIM) and results in a Final Status Survey report.

  • Required Notifications and Document Storage

    In some cases the findings may be shared with regulatory agencies (e.g. in the case of a formal request to terminate a radioactive materials license) or other interested parties such as a property manager or owner who is repossessing the affected property at lease termination. Provisions for archiving of the report must consider the need for retrieval in support of future property transactions.

News & Updates
  • 6.22.14
    On April 8, 2014 the ESI radioactive waste storage and hazardous waste transfer facility located in Baltimore, MD was audited by CHWMEG, Inc. A non-profit trade association comprised of manufacturing and other "industrial" companies, CHWMEG’s interest is to provide efficient oversight for management of the waste related aspects of environmental stewardship.
