would be required to adhere to Resource Conservation and Recovery Act (RCRA) requirements for waste classification and disposal. Based on the classification of waste, the disposal of construction debris would comply with RCRA provisions, as necessary. Hazardous waste sent off-site for disposal would require disposal documentation; hazardous waste manifesting procedures would be followed with appropriate “cradle-to-grave” record-keeping and tracking performed. Based on RCRA requirements, the generator of hazardous waste during construction would be the responsible party and would be so designated on the waste disposal manifests. The responsibk party would continue to compile and submit annual reports on waste generation volumes and rates.

Environmental Impacts

Excavation work may encounter buried construction debris and other hazards. In lieu of subsurface testing, specific management practices may be required of the responsible party to avoid or minimize delays in the construction schedule and to protect human health and the environment. In all cases, if such debris were encountered, work would stop. Management and proper disposal of buried debris encountered during demolition and construction activities would be in accordance with all local, state, and federal regulations.

The responsible party would manage hazardous materials and dispose of all wastes generated during construction, according to applicable federal, state, and local regulations. There will be designated, separate storage areas, secondary containment when appropriate, and buffer zones established near sensitive receptors. All stationary fuel tanks will have secondary containment and will be managed so that spills are prevented. All hazardous material containers will have proper labeling as required under OSHA’s Hazard Communication Standard. Spill Prevention and Response Plans will be developed and implemented. Material safety data sheets (MSDSs) will be available for review. Each construction contractor will be responsible for the proper identification, containerization, labeling, storage, manifesting, reporting, transport and disposal of all hazardous materials and regulated wastes generated during construction. Impacts related to hazardous waste generation, storage, treatment, and disposal would not be significant. Handling and storage of hazardous materials would be performed in accordance with manufacturer’s specifications. Grounds and building maintenance would require the use of pesticides and herbicides to control plant and animal pests. The site and any landscaping would be designed to reduce the use of fertilizers and pesticides. The responsible party would be responsible for handling and administering these materials in compliance with the appropriate federal and state regulations, and i-"pacts would not be expected to be significant

The implementation of the proposed alternative may possibly generate hazardous wastes during construction. Asbestos-containing materials and lead-based paint debris may possibly be generated during demolition. Since the responsible party would be responsible for following all applicable laws and regulations during construction, demolition, and operation of facilities, impacts related to use hazardous materials are not
