Show Alternative B: Development of cooperative programs ( preferred alternative) This alternative would entail the development of a cooperative program with SRP to review and share ground- water data collected near the ash disposal site and to receive information regarding reclamation and stabilization activities ( and the results of revegetation trials) in the ash disposal area. In addition, it would involve cooperation with Utah's Bureau of Water Pollution Control and the Nuclear Regulatory Commission in order for NPS to receive hydrologic monitoring data submitted by Plateau Resources on its uranium mining and milling operations in Shootering Creek. Based on assessments of the initial data, the need for additional monitoring locations could then be evaluated. With these two cooperative programs in place, the potential for downstream effects on the water resources of the NRA can be evaluated using the site- specific information provided by the cooperating entities. Alternative C: Site- specific monitoring For this alternative, the comprehensive hydrologic monitoring program for the recreation area would specifically address hydrologic concerns associated with the ash disposal site and Plateau Resources' uranium mining and milling operation. 11 I. N. 3. Recommended course of action. Alternative B, the development of cooperative programs with the private entities and/ or agencies responsible for regulating energy- related activities, is recommended. This would provide NPS with a cost- effective means of assessing potential impacts on the water resources of the NRA from waste disposal activities on adjacent lands. 111. O. Management of Hazardous Materials Spills IM. O. 1. Statement of the problem. An Oil and Hazardous Substance Spill Contingency Plan has been drafted for Glen Canyon NRA as required by the Clean Water Act. The plan describes a policy for containment and cleanup of spills on water and establishes response procedures for use at Glen Canyon NRA. Hazardous materials spills at Glen Canyon are considered infrequent since careful planning and safe operating practices are emphasized to minimize accidents. When spills occur, however, they usually originate from fueling facilities associated with the marinas on the lake. A fuel tanker operates on the lake between the Wahweap and Dangling Rope marinas, keeping the latter facility supplied with boat gas and diesel fuel.
