The plan in <br />addition to sampling will include the collection and submittal frequency and format <br />of sampling results and meta data. Contact CDPHLF/WQCD West Slope 401 <br />Coordinator (John Hranac 303 692-3586) for approval. <br />• Monitoring will include measurement of flow in cubic feet per second and water <br />quality for dissolved oxygen, pH, E. coli, ammonia, nitratelnitrite, cadmium, copper, <br />lead, manganese, selenium, silver, zinc, and total hardness. Detection limits and <br />quantifiable units for all of the parameters will be low enough to be able to compare <br />the sampling results against the segment stream standards. <br />• After completion of the Long Hollow Reservoir and filling of the reservoir has <br />begun, sampling sites located above the reservoir on both Government Draw and <br />Long Hollow will be established collecting both flow and water quality information <br />available for comparison with the downstream sampling location. <br />• Sampling will continue for 5 years after the completion of the dam and storage of <br />water begins., After 5ycars, the need for sampling will be reviewed by <br />CDPIIR/WQCD annually to see if the objectives of the plan are met. <br />Sampling frequency will be quarterly and staggered so that after 3 years a sample <br />will have been collected from each calendar month at nearly the same calendar day <br />i.e. on the 150' of the month. The sampling cycle will repeat after 3 years. <br />If you have any questions or need additional information, please contact me at (303) 692-3586. <br />Sine ely, <br />John Hranac <br />Water Quality Assessor <br />Water Quality Control Division <br />Colorado Department of Public Health and Environment
