<br />Mr. Tony Waldron, CMLRD <br />August 1, 1989 - page 2 <br />Construction procedures as outlined in permit section 3.7.2 (haul roads) will <br />be followed. Culvert sizing calculations are in Section 4.8.1.2 of our <br />current permit. A 36" culvert will be established in both East and West <br />Buzzard drainages. <br />Also enclosed is an updated sheet 4 of 4 roads map (M-9). A culvert installed <br />in June, 1989, (A-6) was not previously identified on this map. This culvert <br />accommodates the primary drainage flow in Middle Pyeatt. <br />A revised table 4.8.1 of our mining and reclamation permit is provided to show <br />current existing and proposed culverts at Trapper Mine. To make this table as <br />current as possible, culverts BC-3 and BC-4 are placed in the existing <br />category as culvert placement will begin shortly after MR-89 approval. <br />Thanks for your cooperation in this matter. Please call if you have any <br />questions. <br />Sincerely, <br />~~~0 -WGLMI/ ~ V ~!l`~ <br />William Agnew <br />Sr. Environmental Engineer <br />WA/jb <br />[CMLRD\AUGO1] <br />Enclosure <br />pc J.M.
