EA Engineering, Science, and Technology _^_..-.-- ““” Project: 296.0074 Revision: DRAFT Page 5-l April 29, 1997 -~__- 5.1. EROSION CONTROLS 5. ENVIRONMENTAL PROTECTION The construction activities will be performed in a manner to have minimal impacts on the surrounding environment. It is anticipated that excavations will be backfilled at the end of each working day to minimize erosion. Soil that is not used as backfill will be staged and covered with plastic until the excavations are completely backfilled. Upon conclusion of the construction activities remaining soil will be spread in a designated area and seeded and covered with straw. 5.2 DISCHARGE PERMITS An air discharge permit was obtained for the pilot study that was conducted at the Navy Fuel Farm. A copy of the existing discharge permit is presented in Attachment E. The existing air permit will be modified for the addition of two additional vapor recovery wells to the existing system. Treated ground water currently discharged to the NASJRB Willow Grove sanitary sewer system and a discharge permit is not required. Treated ground water from the new remedial system will be discharged to the sanitary sewer by way of a new below-ground discharge line that will be installed during the construction activities. The additional discharge flow rate that will be obtained as part of this new system configuration will not require an additional discharge permit. The Public Works Department has been notified of the increase in discharge flow rate and have approved the modification. 5.3 BUILDING AND CONSTRUCTION PERMITS Building and/or construction permits are not required for this expansion to an existing pilot remedial system. The construction of a concrete pad, the erection of a temporary building, and electrical connections to an existing electrical service will require coordination with NASJRB Willow Grove Public Works and/or the office of the Resident Officer in Charge of Construction. System schematics, site plans, and equipment specifications will be provided to the appropriate NASJRB Willow Grove personnel to facilitate the field construction activities. In the event of conflicting schedules with other onsite construction projects, EA will take direction from Northern Division and the Resident Officer in Charge of Construction office.

Project: 296.0074 Revision: PRAFT Page 6- 1 EA Engineering, Science, and Techology April 29, 1997 6. WASTE MANAGEIVEN’I’ 6.1 WASTE DISPOSITION Waste materials to be generated as a result of remedial action activities include POL, granular activated carbon, asphalt, and soil. Handling, transportation and disposal of waste materials will be conducted in accordance with applicable federal and state laws, as well NASJRB policies and procedures. Materials transported off site will be manifested on the appropriate Bill of Lading to document the type of material, quantity, and final destination and disposition of the waste. POL product will be collected in a storage tank. When sufficient quantity of product has accumulated in the tank, it will be transferred to a tanker for offsite disposal. Granular activated cat-bon (GAG) units are used in the treatment of the recovered ground water. GAC will be removed from the units and transported off-site for regeneration. Waste asphalt will be generated as a result of trenching and excavation activities. A staging area consisting of a roll-off container will be established on site. Waste asphalt will be stockpiled in the roll-off container prior to off-site transportation and disposal. Soil will be generated from trenching and well retrofitting activities. Excavated soil will be disposed on-site by spreading the soil in designated areas. As soil is excavated, it will be staged adjacent to the location from which is was excavated. Soil which can be used as backfill will be placed back into the trench. Excess soil or soil not meeting specifications for backfill will be spread in the designated on site areas. 6.2 TRANSPORTATION AND DISPOSAL SUBCONTRACTORS The following provides information on the subcontractors to be utilized for the off-site transportation and disposal of waste materials. Each of the subcontractors listed below has been providing services to NASJRB.
