CNAPTERTHREE Enulronmental Consequences Pipeline Corridor Potential impacts to transportation during construction and operations would be the same as described for the Proposed Action. Parachute Site If the rail spur is operational by the time construction begins, rail traffic would increase on the reactivated rail spur under the Agency Preferred Alternative. It is estimated that construction activities at the Parachute Site would generate approximately 3 rail cazs per day, or about 15 cazs per week, between about September 1999 and Surruner 2000. Consequently, truck traffic volumes during constmction would be reduced by approximately 6 to 8 truck trips per day, which represents a 9 to 12 percent reduction under the Agency Preferred Alternative. Truck volumes during operations would be the same as the Proposed Action. 3.15.2 Unavoidable Adverse Impacts Unavoidable adverse impacts related to increased rail activity during construction of the Parachute Site would increase under the Agency Preferred Alternative. Unavoidable adverse impacts to traffic volumes and related increases in accidents and highway wear and tear during the Parachute Site construction would be slightly reduced from the Proposed Action. Unavoidable adverse impacts during operations would remain the same as the Proposed Action. 3.16 HAZARDOUS MATERIALS 3.16.1 Direct and Indirect Impacts American Soda would comply with the applicable federal and state regulations for the Yankee Gulch Project regazdless of alternative. Hazardous wastes aze not expected to be generated from the mining operations. The product to be transported in the pipeline is not considered to be a hazardous material under DOT regulations, or a toxic chemical as regulated by EPCRA, or a hazardous substance under CERCLA. Under the Agency Preferred Alternative, the likelihood of adverse effects may be reduced by the development of the preliminary Response Plan, and spill contingency and materials management plans for the Piceance Site, pipeline and Parachute Site. The ROD issued by the BLM would also have a condition of approval requiring compliance with applicable regulations. Regarding solid waste, new information on waste types and generation was developed since the Draft EIS. No significant impacts are anticipated, which is similaz to the Proposed Action. Construction Phase During the construction phase, solid wastes generated by the Yankee Gulch Project would consist of waste paving materials, such as concrete and asphalt; wood waste, such as pallets, crates, and assorted lumber; metallic wastes, such as sheet metal, pipe, and wire; insulation . material; plastic wraps and packaging materials; paper and cazdboazd; and general refuse, including food waste and paper and plastic packaging.
