C, -5- VZI. Rules 2.04.7(3), 2.05.6(3)(ii), 2.07.6(2)(c) and 4.05.15 - [dater Rights and Replacement The Division has reviewed the application for compliance with respect to water rights and replacement requirements of the regulations. Information on water rights in the area can be Found on page 18 and in Exhibit 13 of the application. The surface water system is designed so that no water rights will be adver- sely affected by the proposed mining operation. The sediment pond is the only structure that impounds water on the site. The sediment pond will be dewatered within 36 hours following any runoff event; thus, any possible downstream users will not be affected. The surface owner at the Nu-Pfine adit has an absolute decree up to 0.1 cfs on water leaving the Nu-hfine adit, for stock watering purposes. The supply of water to this user is dependant upon the water draining from OC b2 into the abandoned Nu-hfine workings. Asa matter of practice, OC b1 pumps ground water into interconnecting workings which then allows the water to flow to the Nu-Mine adit. Therefore, the proposed operation will not adversely affect the water rights of this user. The only foreseAable adverse effects the mining operation could have upon water rights holders would be the impoundment of water in the sediment con- trol system or an intierference in t1~e discharge of water from the Nu-Mine adit. However, since the proposed operation is designed to allow for the flow of water in a manner to avoid injury to water rights holders, there are no anticipated adverse affects on the water rights users in the area. The proposed application is in compliance with requirements addressed in this section. _VIZI. Rule 2.05.6(3) - The Assessment of Probable Cumulative Hydrologic Impacts The probable a.tfects of the mining operation upon the ground water regime are projected to be negligible. The mine is hydrologically isolated from the surrounding areas by Faults. The minor amounts of water flowing from the working Face are pumped to the bottom of the slope and flow into the abandoned Nu-Mine workings. The ground water then exits the caved Nu-Mine adit and flows into a series of two stock ponds. it is unlikely that any excess water would flow from these ponds because of their size relative to the small amount of flow. In the event the water did flow from the ponds, it would flow through a vegetated channel into Coal Creek, a tribu- tary to Ohio Creek. Any water entering Coal Creek is projected to have a negligible affect since the water leaving the Nu-Mine adit meets all the required effluent standards. The water exiting the Nu-Mine adit will be continually monitored to insure that there are no adverse effects. (See page 16a of the application for a description of the ground water monitor- ing program.) Thb probable affects of the mining operation upon the surface water in the area are also projected to be negligible. All surface drainage from the
