TR -84 removed the culverts and ditches in the Pond J watershed from Volume <br />Exhibit 8, placing them in Volume XI, Appendix B.

Revised maps include several undesigned culverts that appear to be part of the <br />mine drainage and sediment control system. Unless they are existing culverts <br />associated with a public roadway or another mine permit and will not convey diverted <br />water or disturbed area runoff in conjunction with mine operations, BRL must submit <br />design information for all culverts associated with mine related structures (Rules <br />2.05.3(3)(c)(i) and 4.03.3(4)). Design information or clarification that these <br />structures are not mine related will be needed for the following: <br />• 6" drain near Culvert B13 - Not located in field. <br />• 18" culvert near pond diversion structure along main haul road - <br />Relocated and assigned name of C -G6 with TR -87 <br />• 18" culvert on the south end of the office parking area -Not located in the <br />field, removed from applicable maps. <br />• 36" culvert on the D Bench - Newly named culvert C -26, design begins <br />on page Exh. 8- 32xxii <br />• Culvert under the conveyor between the two stockpiles on the D Bench - <br />This is Culvert C -5 <br />• 12" culvert at the outlet of Culvert C12 - Will be named culvert C -22, <br />design included and begins on page Exh. 8 -32ix.
