USA performs MEC characterization to identify potential risks and develop appropriate response alternatives to reduce human risks associated with MEC and munitions constituents (MC). By working with an accepted, consistent framework, we are able to streamline project activities, make more consistent decisions, and have the necessary documentation to support those decisions. USA focuses on hazard management choices that must be made during site evaluation and cleanup of MEC under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In addition, our MEC characterization responses fulfill the National Contingency Plan (NCP) requirement for site-specific risk assessments under CERCLA. 

Examples of MEC characterization projects performed by USA include:

Engineering Evaluation/Cost Analysis (EE/CA) at Camp Chaffee, AR; and Williams Field, AZ; Frankford Arsenal, PA; and Waikoloa, HI

• Comprehensive Site Evaluations (CSEs) for USACE, Omaha at multiple Air Force Bases
• Range Reconnaissance at multiple sites including Ft. Richardson, AK; Ft. Greely, AK; Ft. Carson, CO; Yakima, WA; Camp Bullis, TX; and Ft. Sill, TX
• Remedial Investigation/Feasibility Study (RI/FS) for U.S. Army Engineering & Support Center, Huntsville (USAESCH) and USACE, Honolulu District at the Popoki Training Area, HI
• RI/FS for NAVFAC Northwest on Adak Island, AK

Since our incorporation in July 1998, USA has contracted on over 660 MEC remediation projects/task orders, to include UXO and munitions debris (MD). We successfully perform these remediation services as a prime contractor and subcontractor.

Some of our larger, prime MEC remediation contracts include:

• $95M, 5-year Munitions Response Actions at Vieques and Other Sites for Navy Atlantic
• $2.175B shared-capacity, 5-year World Wide Remediation Services (WERS) Contract for USAESCH. To date USA has been awarded 16 task orders.
• $68M/5-year Munitions Response Contract for Navy Pacific Division. USA received 23 task orders with two MEC clearance projects on Adak Island, AK, and three projects for MEC removal on Vieques Island, Puerto Rico.
• $1.155B shared-capacity, 5-year Munitions Response Services program for USAESCH. USA received 26 task orders and performed MEC remediation worldwide, including sites in the U.S., Iraq, and Japan.
• $120M Munitions Response Services Contract for USAESCH. Under this contract USA received 27 task orders, including remediation projects on active U.S. ranges.

USA performs MEC disposal in accordance with all Federal and relevant state and
local requirements. USA recently received a Perfect Record Award from the National Safety Council for performing over one million hours without a lost time accident.
