2. The applicant will conduct monitoring of surface water 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 pazameters and annual full suite water quality <br />samples. <br />(2). Mine 2: Monthly field pazame[ers and semi-annual full suite water <br />quality samples. <br />NPDES sites at Mines 1 & 2 (sediment pond outlets) will have monthly <br />maintenance, service, flow measurements, field pazameters and quarterly full <br />suite water quality samples. <br />E. Stream Buffer Zones <br />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 nipazian vegetation will be reestablished. The buffer <br />zone variance is granted for the azea located along the southern disturbed area <br />collection ditch to Pond 007 (4.05.18(1)). The azea will be no lazger than .4 acre <br />at any time during mining and reclamation activities. <br />F. Water Rights <br />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 />Impact 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 />
