• (Page 2) • MINE ID # OR PROSPECTING ID # M-90-021 INSPECTION DF,TE 04/29/98 INSPECTOR'S INITIALS~R ~Q_ OBSERVATIONS This inspection was performed by the Division as part of its monitoring of 112 construction material permits. The operator was contacted about the inspection and was present at the site throughout the inspection. The required :permit ID sign and permit boundary markers were observed as present. The sign was posted on the entrance gate and the permit had a perimeter fence. Mining has c;eased and reclamation is well underway. There was no mining equipment or stockpiles from the pit present. Some of the land near the entrance was being utilized as a staging area for a nearby project United is involved with. Equipment for that project included a semi-trailer, fuel tank and small miscellaneous parts. The significant structures at the site still include the overhead powerlines along the north and south aides of the permit area. Excavation of the pit adequately avoided impact to the lines and poles. The pit has encountered groundwater, which was the plan, and the configuratioci has produced an irregularly shaped pond. The sideslopes have been well prepared, lezcving gradients of 3:1 or less. Most of the slopes, with the exception of the northeast corner, have been topsoiled. The northeast corner of the pit will be finished by placing additional fill material, to raise the rough part of the bank there and eliminate the shallow portion of the pond in that corner. Th:.s may also help reduce an annual weed problem at that location. The fill material was being placed in a large berm along the north side of the permit area. The tonic of "overburden deve~cmment waste" is noted as a problem on page one of th's repo r That is related to the placement of the aforementioned bermed material on the north edge of the permit, This material is being generated off site, and is not related to the mining operation. The operator stated that some of it would remain onsite for use in reclamation, in which case its removal may not be a necessity. An estimate of the total volume is about 4,000 cubic yards. The material appears to be soil, and the portion to remain onsite will be used for fill on the north edge of the pond, and to plate the north bank. However. since ; s ;mpo a ion for use has not been brought to the attent'on of the D'v's'on through the Notice proced ~~*+ra;noa ~~ a++~a a ~ 5(91 ;r ;s present~y a prob~em 'c'he op~Qrator must provide the N'or' informat;on for the Division's review Tf approved for use the problem will be abat.P~• ;t not approved the material will have to be removed Please see the corrective acr_ion and date on the last nave. The operator stated that the material will be graded and seeded this season, but that should be postponed until the Notice is submitted for review. There is a patch of Russian knapweed (ACraptilon repens) on the north side of the pond also. Much of the imported fill appears to cover some of the patch. The plants are scattered along the north fer..celine, under the powerlines and in small areas of the pond banks. This plant is on the list of the State weed law, and must be controlled. It is recommended that the operator pr~~pare a plan in consultation with the county weed authority, and begin implementation this season. On-the-ground improvement should be evident within three years, if the plan is adequate and followed. The site generally is becoming well reclaimed, and is overall clean and orderly. There were no other problems noted. For all questions or comments pertaining to this report, please contact this inspector at the address or phone shown below:
