Show IV. A. 4. Heavy metals in fish flesh. The National Park Service will propose a minor expansion of the National Contaminant Biomonitoring Program ( NCBP) to include striped bass from Lake Powell as a species analyzed for lead, cadmium, mercury, arsenic, selenium, copper, and zinc. Muscle tissue as well as whole fish concentrations would be evaluated. This monitoring would be implemented through coordination with the NCBP. If necessary, funding for the additional tests would be provided at an analytical cost of approximately $ 1,000-$ 2,000 every other year. IV. A. 5. Range management practices. A one- year monitoring effort will be undertaken to compare the bacterial contamination in springs, seeps, and catchments on cattle range with control springs on ungrazed range. ( This project will, if possible, be undertaken preparatory to writing the Grazing Management Plan.) When the opportunity arises, samples will be taken before and after development of a new water source for cattle in a situation where the predevelopment water was not used by cattle. This will document any change in bacterial status of the water. Fecal coliforms, fecal streptococci, total coliforms, water temperature, pH, turbidity, and specific conductance will be measured using instruments and laboratory facilities in the park. The need for follow- up monitoring will be evaluated based on first- year results. IV. A. 6. Mineral extraction. A baseline monitoring requirement for mineral developers is proposed as outlined by Flug ( 1985) to enable NPS personnel to assess the effects of mineral extraction on water resources. The Service will request the Bureau of Land Management to include the monitoring as a lease requirement for tar sand leases that could affect waters of the NRA. Up to eleven stations could be monitored for the three tar sand areas surrounding the NRA. However, at any one time only the stations measuring waters affected by specific operations would be required; thus, the monitoring would be implemented on a case- by- case basis. Table 5 lists the monitoring stations required to obtain an adequate data base for each tar sand area. Other land managers may require additional stations. Tables 6 and 7 list the parameters to be measured at each station. Ground- water monitoring would occur at wells developed near the designated stations after consultation with the NPS Water Resources Division on siting. Wells would be located away from the zone of lake bank- storage influence. For tar sand operations, up to two years of data under this program would be required from developers prior to approval of operations. Monitoring would have to continue during development activities and production and throughout post- operational reclamation for a period to be determined by the NRA, based on the nature of the disturbance. Developers would bear the cost of the monitoring. This requirement would become a stipulation on leases granted for tar sand development within the areas of concern. 68 |
