-~- U.S.G.S. studies a[e regional, and ate not as intensive as those on-the-ground surveys performed by an applicant. In addition, the applicant has submitted only one water quality sample and flow measurement for each of the two springs identified. This is not sufficient to show the seasonal variations in water quality and quantity, or to identify the flow regime of the springs. The applicant should perform his own spring au[vey fo[ the permit area and adjacent area, and provide sufficient data to identify seasonal variations in quality and quantity. 32. The adequacy of Section 2.04.7(3), Alternative Water ~upply Information, will be reviewed after the Division has reviewed the app)icant`s revised discussion of probable hydrologic consequences. 5: ,, ~~' Pursuant to Rule 2.04.7(4)(d) the applicant provided Map ~w14, Water Rights and Usage. The records of the Staie Engineer's Office list several irrigation ditches on Fish Creek (Koll Ditch, Mager Ditch, Soettler Ditch lat. Enl, and Corliss Ditch) and on Foidel Creek (Lieske Ditcri) downstream from the proposed mining operation which are not shown on Map 14. (See attachment A.) The applicant should revise Map 14 of the permit application to identify the point of diversion, and the are, of use fo[ these diversions. The applicant should also discuss the nature of use and the status of the diversions. ~..~~\~ Ponds. Impoundments. and Diversions '~~ 1. Page 4.05-7 and Exhibit 10 state that sediment accumulation in ponds will 6e monitored as requited by 4.05.6(3). CYCC should describe specifically how sediment will be monitored. CYCC may want to consider installing a staff gage in each pond to assist in identifying the 601 sediment storage volume level. 2. Page 4.05-21 states that the sediment control design plans and apecificatione presented in Exhibit 6 have been certified by a professional engineer. The Division could not locate this certification. CYCC should clarify the location of the certification or include the certification in the permit revision application. 3. On page 4.05-24 and 39 the applicant requested a variance from Rule 4.05.6(1)(c) which requites quarterly inspections of ponds. Due to the size, location, and anticipated usage of the ponds, the Division plans to deny this request. It should be noted that these reports are simple and quick to complete and need not be conducted by, signed by, oc certified by a professional engineer. The Division has a suggested report form the applicant may wish to use to complete this requirement.
