Operating Range Maintenance and Range Repair

USAF Academy CATM Range, Colorado

Overview: The US Air Force Academy (USAFA) contracted MT2 Sole Source to perform operating firing range maintenance and repair of two firing ranges. The ranges had been temporarily closed due to potential ricochets from the main impact berm. USAFA selected MT2 based on research indicating that MT2 was highly qualified and experienced; cost-effective price, and MT2 was highly recommended by other organizations.

MT2 Services: Due to the need to make this range operational as soon as possible, the project was performed during the winter season. MT2 tasks included: MT2 utilized its proprietary and specialized systems including vibratory and finishing plants to provide over 95% lead reclamation from the main impact berm and range floor; MT2 performed range reconstruction enhancements including slope stabilization by installing geogrid membranes, seeding and installation of erosion control blankets to protect berm slope and configuration; Stormwater management; Air monitoring compliance at an active facility; and MT2 met Base requirements for security and traffic control.

Outcome: Even in severe winter weather conditions, MT2 completed the project within schedule; the completed range project met the Academy’s technical and training requirements; recovered lead was of high recycle value and provided the Academy with an off-set credit for project costs. USAFA completed a project review and graded MT2 with excellent marks.

Liability Mitigation

CRANE NAVSEA Lead Removal and Remediation – Crane, IN

Overview: MT2 was contracted to provide lead removal and lead contaminated soil remediation services. The NAVSEA site consists of approximately nine priority firing range sites and including 100 M Sand Pit, 300 M Sand Pit, 25 Yard Target, Berm #1, 600 Yard Target, 600 Yard Backstop, 200 Yard Target, 1,000 Yard Target, and 1,000 Yard Backstop

MT2 Services: The results of the site investigation found levels of lead above Indiana Department of Environmental management (IDEM) Risk Integrated System of Closure (RISC) for construction worker exposure and potential migration to groundwater and lead above hazardous levels as measured by TCLP. The project objective was to provide necessary and appropriate remediation and maintenance activities for the NAVSEA facilities following US EPA Best Management Practices for Firing Ranges, to minimize cleanup costs and address future potential liabilities that could negatively impact future use plans for NAVSEA. MT2 excavated, screened and treated lead-contaminated soils. Soils were treated with MT2’s proprietary stabilization reagent, ECOBOND® to meet the TCLP Pb requirements (concentrations below 5.0 mg/L). Treated soils were confirmed to meet action levels and TCLP requirements through sampling performed using laboratory analyses performed at an independent certified laboratory.

Outcome: MT2 excavated approximately 900 yards of lead-impacted soils from berms and pits associated with multiple rifle ranges. These soils were screened to separate bullets for offsite disposal and then tested for TCLP Pb. Soils were then treated with ECOBOND® to below the threshold of 5 mg/L for reuse on the site. Additionally, approximately 400 yards of soils were excavated from range soils that had the potential to impact groundwater. These soils were tested and soils above the TCLP lead threshold were treated with ECOBOND® for reuse onsite.

Trap and Skeet Range Cleanup and Closure

Offutt AFB, NE

Overview: MT2 performed turnkey environmental firing range remediation at the former Offutt AFB Trap and Skeet Range to allow land redevelopment and expansion of the airfield. This project included management of an active waterway along with meeting strict security requirements for an active airfield. MT2 served EA Engineering, Offutt AFB, and the US Army Corps of Engineers for the execution of this project.

MT2 Services: This project was performed in high security areas as well as within an environmentally sensitive active waterway. MT2 conducted: specialty excavations to reduce soil quantities for off-site disposal; sediment removal in an active waterway; stormwater and air compliance; and in-situ ECOBOND® treatment of soils thus allowing nonhazardous offsite transportation and disposal. MT2 met base security and traffic control requirements. MT2 provided efficiencies through onsite survey control and effective client communication.

Outcome: Offutt AFB is now able to reuse this land for redevelopment; the removal of contaminated sediments to the active waterway met environmental requirements and reduced environmental risks, ECOBOND® treatment and field efficiencies provided significant client savings.
