-3- U.S.G.S. studies ate 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 spcings 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 survey for the permit area and adjacent area, and provide sufficient data to identify seasonal variations in quality and quantity. 2. The adequacy of Section 2.04.7(3), Alternative Water Supply Information, will be reviewed after the Division has reviewed the app]icant's revised discussion of probable hydrologic consequences. 3. Pursuant to Rule 2.04.7(4)(d) the applicant provided Map 14, Water Rights and Usage. The records of the State Engineer's Office list several irrigation ditches on Fish Creek (Koll Ditch, Mager Ditch. Boettlet Ditch 1st. Enl, and Corlise Ditch) and on Foidel Creek (Lieske Ditch) downstream from the p[oposed mining operation which ate 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 area of use for these diversions. The applicant should also discuss the nature of use and the status of the diversions. eni eF TA.t c. bobby %h1Cl, Ponds. ImUOUndmente. and Diversions 1. Page 4.05-7 and Exhibit 10 state that sediment accumulation in ponds will be monitored as required 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 1n identifying the 60i sediment storage volume level. 2. Page 6.05-21 states that the sediment control design plane and specifications 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 requires 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, or certified by a professional engineer. The Division has a suggested report form the applicant may wish to use to complete this requirement.
