2 A) Page 4-73 states that "detention ponds will serve as sediment traps until filled naturally." Is this ok to just leave these ponds without removal? Are they considered permanent impoundments? B) 1988 findings pg.7 comments that the No.l mine is expected to fill with water by 1993 with inflow decreasing until then. Has this happened? Now that it's 1993 do we need to follow up on this or have the operator document it? 3) I realize Technical Revision 12 changed the post-mining land use at the loadout only from pastureland to industrial/ residential/agricultural discrepancies include: A) Do any success criteria standards apply on the loadout area since this land-use change? Page 4-99 of the permit still commits the post-mining land-use at the loadout to irrigated pasture and haylands. Page 4-90 of the permit retains the success criteria for irrigated pasture and haylands. This would indicate to me that the operator still needs to comply with these standards or apply for a revision to these standards on the appropriate loadout area. B) TR-12 approval form states that pages 4-99(b)-(eland 4-100(a)-(c) were revised. I was unable to locate pages 4-100(b) and (c) either in the permit or in the revision file. Pages 4-99(b)-(e) exist in the revision file but need to be incorporated into the permit. C) Page 4-100(a) has some unusual wording on cover standard still required on the Diamond-A Ranch parcel. This cover standard applies to erosion control and states that cover is considered adequate if 20 or more acres of this parcel are covered by roads, buildings, other structures or vegetation. Can the balance of the acreage remain bare? Or since the zoning has changed this is adequate for erosion control? 4) Revegetation success criteria are as follows: Mine Site: Cover and productivity of the reclaimed Mountain Shrubland dry phase will be compared to the Mountain Shrubland reference area. "if the reclaimed area is comparable to the reference area, the reclaimed area will be considered successfully reclaimed. A) What does the operator mean by comparable? Will the reclaimed area need to show 100% cover and productivity of the reference area or is a 90% comparison with a 90% confidence interval implied? This standard needs to be better defined. B) A statement on page 4-64 says,"The Riparian woodland and Mountain Shrubland Moist Phase are minor communities for which no separate vegetation success criteria is required:' My understanding of this statement is that the same standards as apply to the Mountain Shrubland Dry Phase shall a]so apply for the 1.9 acres included within the Riparian Woodland and Mountain Shrubland Moist Phase vegetation communities.
