Mid-Term Permit Review - 5 - March 25, 1986 <br />i) The operator must submit an acceptable "sediment pond <br />maintenance and sediment disposal plan", which should then be <br />incorporated into this section. The Division is aware that a <br />technical revision has been submitted for such a plan, however <br />additional work needs to be done on this revision. This <br />revision should be submitted in a timely manner so it can be <br />implemented during the upcoming field season. <br />j) The operator should incorporate the recently approved riprap <br />technical revision into the permit. Information should be <br />added which identifies the lithology of the riprap to be used <br />(i.e., type of sandstone). <br />k) The Division is in possession of five diagrams prepared by <br />CH2M Hill depicting sediment ponds 1-3. Exactly which ponds <br />are these, and where do the diagrams belong in the permit <br />application? <br />1) The Gas line slide narration does not seem to belong in this <br />section. The operator should consider relocating this <br />narrative. The use of an appendix which is referenced in the <br />discussion of the haul road is one possibility. <br />m) The truck scale minor revision, road culvert minor revision, <br />and lower pond grading minor revision should all be <br />incorporated into the permit application. <br />n) The appendices at the end of this section should be properly <br />located, marked, and referenced. <br />Section 2.05.4 - a) This section projects a volume of 325,000 cu. yds. <br />as needed to backfill the pit. This estimate does not agree <br />with the 620,000 cu. yds. actually moved. The text should be <br />changed to reflect the actual volume. Some of this information <br />seems to be included in the Revegetation and Haul Road <br />technical revisions, but r~ias never incorporated into the permit. <br />b) The revegetation section should be revised to incorporate <br />the Revegetation Technical Revision. These changes should <br />additionally reflect compliance with the stipulations included <br />in the revision approval. References to any practices which <br />were not utilized (i.e. stubble mulching) should be modified. <br />A specific revegetation monitoring plan, which sets forth the <br />exact years of sampling should also be included. This plan <br />should account for the fact that seeding was accomplished over <br />more than one year. <br />c) Regraded overburden sampling data and reapplied topsoil <br />sampling data should be included in the discussion of actual <br />reclamation accomplished on site. This discussion should be <br />incoroorated into the proposed reclamation narrative, to bring <br />the permit application up to date. Implementation of the toxic <br />
