Adapting MARSSIM for FUSRAP Site Closure
R. Johnson, L. Durham, C. Rieman, R. Hoover
The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (EPA 2000) provides a coherent, graded, technically defensible, performance-based process for establishing that cleanup requirements have been met for surfaces at radiologically contaminated sites undergoing remediation and closure. Since its publication, MARSSIM has gained increasingly broad support as the closure process of choice. A good example of this support can be found within the Formerly Utilized Site Remediation Action Program (FUSRAP), where most if not all sites attempt to base their site closure process on MARSSIM. The U.S. Army Corps of Engineers (USACE) Buffalo District is responsible for remediating several radiologically contaminated sites related to the Manhattan Project under FUSRAP. These sites currently include the Ashland 1, Ashland 2, Linde, Seaway, and Niagara Storage sites in New York, and the Painesville and Luckey sites in Ohio. For those sites where remediation activities are either complete (such as the Ashland 2 site) or underway (such as the Linde site), the closure process has been modeled after MARSSIM. Unfortunately, applying MARSSIM to sites is often complicated by the constraints of MARSSIM's scope and assumptions. This fact has been particularly true at FUSRAP facilities, with legacy issues associated with sparse characterization data, potential subsurface contamination, and Records of Decisions (RODs) that have been derived primarily from Applicable or Relevant and Appropriate Requirements (ARARs).
