RULE 4 PERFORMANCE STANDARDS <br />Colorado Oil and Gas Registered Facility Locations <br />There are three locations within the proposed permit boundary extension for the Collom Mining <br />Area (Map 11 B — Drill Hole Locations) that are identified in the Colorado Oil and Gas Conservation <br />Commission database. They are described as follows: <br />1) ID# 05-081-07203 — Plugged and abandoned oil exploration well. Owned by Infinity Oil & <br />Gas of Wyoming, completed in December, 2004. Plugged and abandoned July, 2005. <br />2) ID# 05-081-06328 — Plugged and abandoned oil expoloration well. Owned by Tiger Oil <br />Company, completed February, 1978. Plugged and abandoned February, 1978. <br />3) ID# 05-081-06339 — Planned oil exploration well location permitted but well was not <br />constructed and the drilling permit was allowed to expire in May, 1978. Owned by Tiger Oil <br />Company. <br />4.09 DISPOSAL OF EXCESS SPOIL <br />Spoil removed from the Collom Lite and Little Collom X pits will be stockpiled in a temporary fill area as <br />shown on Maps 23B and 29C (Temporary Spoil Pile Design). Map 29B shows the timing of spoil <br />grading completion and the initiation of reclamation activities. Volume 20, Exhibit 23, Item 1 provides <br />the geotechnical report for the temporary spoil pile. Colowyo expects a swell of excavated materials; <br />therefore, all of the material stockpiled in the temporary fill will remain at the conclusion of the project as <br />shown on Map 19C. No excess spoil is anticipated for the mining and development of the Collom Lite or <br />Little Collom X Pits. Additional discussion of the temporary spoil pile can be found under Section <br />2.05.3(6). <br />CONSTRUCTION PLAN <br />All available topsoil will be removed and either stockpiled for later use or direct haul replaced to a <br />reclaimed area. No excess spoil is expected under the current Mine Operation Plan. Should disposal of <br />excess spoil be anticipated, a construction plan will be developed. Colowyo will follow the <br />recommendations for excavation and fill construction as described in Shannon and Wilson's report in <br />Exhibit 23, Item 1. <br />INSPECTION PLAN <br />Should plans change and permanent disposal of excess spoil occur out of pit, during construction of the <br />Fill, Colowyo will provide the following information in certified reports as required by Rule 4.09.1(11). <br />Inspections will be conducted at least quarterly during the construction period and during the <br />following specific construction periods. <br />a. removal of topsoil and organic material <br />b. placement of underdrain system <br />C, installation of surface drain system <br />d. placement of fill material to insure that the largest rocks are reaching the bottom of the <br />dump face and that the formation of voids than adversely affect mass stability are <br />prevented and <br />e. revegetation <br />Collom — Rule 4, Page 26 Revision Date: 9/28/11 <br />Revision No.: PR -03 <br />
