Hazard Assessment (MEC HA) Methodology Technical Work Group (TWG)
In spring 2004, EPA convened a work group with other federal agencies, states and tribal participants to develop a hazard assessment
methodology for munitions response sites. The methodology is intended to be used in the CERCLA process to help project teams evaluate
current or baseline explosive safety hazards to people, as well as the relative reduction hazards associated with CERCLA removal or
remedial action alternatives. The TWG has developed the following technical reference documents, outreach efforts and other materials
related to this initiative.
Interim Munitions and Explosives of Concern Hazard Assessment (MEC HA) Methodology
This link contains the October 2008 Interim MEC HA Methodology Document and Appendices. The MEC HA methodology was developed as a tool
to assist site managers and regulators in evaluating explosive safety hazards to people at munitions response sites (MRS) consistent
with the Comprehensive Environmental Response, Compensation, and Liability Act - the federal law governing the cleanup of contaminated
sites. In addition, this link contains the Final Responses to Comments from the January 2007 to March 2007 Public Review on the November
2006 Draft Document.
Project teams can use the methodology to evaluate baseline explosive hazards to people based on current or reasonably anticipated land use activities. The methodology can also be used to evaluate relative reduction of explosive hazards to people through CERCLA removal or remedial actions. The MEC HA methodology is designed to be a collaborative process that draws on the collective experience and understanding of project team members and stakeholders. The Interim MEC HA Methodology will be applied on a trial basis for 2 to 3 years at MRS where a munitions response is ongoing. At the end of this time frame, the effectiveness of the MEC HA methodology will be evaluated, and may be updated as needed. More information on the MEC HA methodology and background can be found at the following web links.
