2. The applicant will conduct monitoring of surface «:ater in a manner approved by <br /> the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iii) and <br /> includes the following: (4.05.13(2)) <br /> a. The baseline program (New Horizon 2 - July 1986 to July 1987) included <br /> monthly visits to maintain, service, take flow measurements, take field <br /> parameters and collect full suite water quality samples. Results of this <br /> program are discussed and tabulated in Section 2.04,7 of the New Horizon <br /> 2 permit application. <br /> b. The current monitoring program will consist of: <br /> (1). Mine 1: Monthly field parameters and annual full suite water quality <br /> samples. <br /> (2). Mine 2: Monthly field parameters and semi-annual full suite water <br /> quality samples. <br /> c. NPDES sites at Mines 1 & 2 (sediment pond outlets) will have monthly <br /> maintenance, service, flow measurements, field parameters and quarterly full <br /> suite water quality samples. <br /> E. Stream Buffer Zones <br /> 1. The Division proposes to approve surface mining activities within 100 feet of a <br /> perennial stream. This decision is based on a finding that the original stream <br /> channel will not be disturbed, water quality and quantity shall not be adversely <br /> affected, and appropriate riparian vegetation will be reestablished. The buffer <br /> zone variance is granted for the area located along the southern disturbed area <br /> collection ditch to Pond 007 (4.05.18(1)). The area will be no larger than .4 acre <br /> at any time during mining and reclamation activities. <br /> F. Water Rights <br /> 1. The water augmentation plan is found in Section 2.05.6(3) of the permit <br /> document. Western Fuels-Colorado has acquired approval from the Colorado <br /> Water Court for this augmentation plan and has a completed well permit for use <br /> of water from Pond 007. <br /> G. Probable Hydrologic Consequences <br /> 1. Lnpact of spoil water quality on the ground and surface water quality: The <br /> available data indicate that a small proportion of the overburden may produce <br /> acid through the oxidation of pyrite. Based on laboratory tests on overburden <br /> 21 <br />
