5.0 ENVIRONMENTAL CONTROLS

5.1 MATERIALS (SOIL, AGGREGATE, SPOILS, CONSTRUCTION, AND DEMOLITION DEBRIS). Evaluate excess environmental media and construction debris generated during the demolition of housing units or other wooden structures for the presence of chlordane or other pesticides prior to onsite reuse or final disposal at a permitted landfill. Waste materials generated from MHAFB projects must be taken to an appropriate licensed disposal facility (TSDF or Landfill), offsite reuse is not authorized. Do not transport soil off the project site unless approval has been obtained from the Contracting Officer after coordination with CEIE/Environmental Office. The definition of "project site" is the immediate vicinity of the construction/demolition activities within the project boundaries.

All soils brought onto MHAFB that will be used as un-encapsulated surface fill material must be approved by the Contracting Officer. If testing is required, test results must be provided to CEIE/Environmental Office for approval/disapproval of material prior to coming on to MHAFB.

All materials must also be approved by CEIE/Environmental Office and the Contracting Officer prior to being taken off-base for disposal at a permitted landfill or if being reused on base. If testing is required, test results must be provided to CEIE/Environmental Office for waste characterization determination of soils prior to onsite reuse or disposal.

All non-hazardous materials shall be disposed of in a permitted off-base landfill in accordance with all applicable local, state, and federal laws.

MHAFB required analytical analysis of soils includes Method 8260/5035 for Volatile Organic Compounds (VOCs), Method 8270 for Semi-volatile Organic Compounds (SVOCs), Methods 6010/7470 for RCRA (8) Metals, Method 8081 for Pesticides, and Method 8082 for PCBs to demonstrate non-contaminated before being accepted for use on the project site. Determination of the number of samples must be made by an environmental professional. An environmental professional must have: a state issued certification or license and three years of relevant full-time work experience; or a Baccalaureate degree or higher in science or engineering and five years of relevant full-time work experience; or ten years of relevant full-time work experience.

5.2 HAZARDOUS MATERIAL (HAZMAT) INVENTORY AND SAFETY DATA SHEETS (SDS). SDS are required as specified in Federal Standard No. 313 for all potentially hazardous materials. SDSs must be submitted by the Contractor within ten calendar days following contract award to the CO for a determination of whether a product is a HAZMAT and what additional requirements may be applicable/necessary.

5.3 APPROVALS. Approval is required before bringing any HAZMATS onto the installation. The Government (HAZMART personnel) shall inventory all chemicals the Contractor brings on to MHAFB or any property under the control of MHAFB. Products which meet the criteria of “Hazardous Waste” must be bar coded and tracked until permanently removed from Government property. The inventory shall be performed prior to commencement of work. Criteria for identifying hazardous waste, is contained in Subpart C of 40 CFR, Part 261.

5.4 NOTIFICATION OF ENVIRONMENTAL SPILLS. If a spill occurs, the person discovering the spill shall make every effort to stop the product flow, when possible, warn personnel, shut off ignition sources, contain the spill, make notifications, and begin cleanup. If the spill is considered an emergency and there is a potential life, health, fire, or other safety hazard, the MHAFB Fire Department shall be notified IMMEDIATELY. Responsible units and activities shall clean up small spills safely and within their capabilities to do so. Generally, a spill of only a few gallons shall be recovered by the responsible unit or activity using absorbent materials or a spill kit located by the site. Recovered product and contaminated materials shall be packaged and staged for disposal in accordance with the installations hazardous waste procedures. Contact the Environmental Office (208-828-6351) for guidance. The liability for the spill or release of such substances rests solely with the Contractor and its agent.

5.5 DISPOSAL. Do not dispose of hazardous waste on Government property. Do not discharge any waste to a sanitary sewer, storm drain, or to surface waters or conduct waste treatment or disposal on Government property without written approval of the CO and Environmental Office.

5.6 HAZARDOUS WASTE POC. Consult with the Hazardous Waste Program Manager (366 CES/CEIE) at 208-828-1684/6351 prior to disposal of any waste.
