t PERMIT#:M-1995-005 INSPECTOR'S MTIALS:ACY INSPECTION DATE:December 15,2020 OBSERVATIONS This inspection was conducted in response to the succession of operator request that was approved on July 31, 2020. The inspection was conducted by Amy Yeldell of the Colorado Division of Reclamation, Mining and Safety(Division). The Orchard Mesa Aggr site is a 112c permitted site that includes a total of 46.10 acres. The site located southeast of Grand Junction, Colorado and is accessed through the Mesa County Landfill. David Forenza of Mesa Agg LLC represented the operator. Additional parties present were Ivan Geer, Bailie Tomlinson, Steve Baker and Robbie Stewardson. The mine identification sign and affected area boundary markers are in place and in compliance with Rule 3.1.12. A sign is attached to the main gate at the permit entrance from the county landfill. The sign has been updated to reflect the new Operator. The permit boundary is delineated by fences and/or t-posts. More frequent boundary delineations may be useful as mining progresses to the west. A scale and scale house is located along the mine access road near the gate to the composting area of the county landfill. Significant mining progress has been made since the acquisition of the permit. Approximately 5 acres has recently been mined since the previous inspection. Active near vertical highwall remains at approximately 2,000 linear feet. Excavations near the north side of the pit are averaging closer to 20 feet as compared to 10-15 feet along the south side of the pit where previous mining occurred. There is a large crushed gravel pile in the center of the pit. Smaller piles of overburden, fines and topsoil stored to west in the newly excavated areas. Mr. Forenza estimates that the pit is producing150 trucks per day. The ramp along the north side of the pit has been improved. It is now a more gradual slope and approximately 24 ft wide. Several pieces of equipment were observed on site. Fuel is currently stored in a mobile double walled tank. There is no water source on site and therefor no washing occurs. Portable water tanks were on site but applications of water for dust suppression was no observed. A large portion of the time spent on site was giving the new Operator an overview of DRMS. Resources such as ePermitting, Laserfiche and eNotify were mentioned. Additionally the Operator intends to submit an amendment to expand the pit in the near future. They are currently working through the county process right now. Moreover a portion of the expansion may be on BLM which will have additional permitting actions to work through prior to filing with DRMS. The Operator was encouraged to obtain the necessary other permit(s) prior to filing with DRMS given our deadlines are generally a tighter turn around for permit review. In the meantime if the Operator intends to conduct exploration activities in support of the future operations a Notice of Intent should be filed. Currently this site is not approved for the import of fill material. In order to import material the Operator must provide the Division with notice per Rule 3.1.5 (9). The notice shall include but is not limited to: a narrative that describes the approximate location of the proposed activity; the approximate volume of inert material to be backfilled; a signed affidavit certifying that the material is clean and inert, as defined in Rule 1.1(20);the approximate dates the proposed activity will commence and end, however, such dates shall not be an enforceable condition; an explanation of how the backfilled site will result in a post-mining configuration that is compatible with the approved post-mining land use; and a general engineering plan stat how the material will be place and stabilized in a manner to avoid unacceptable settling and voids."This Notice should be submitted in the form of a technical revision.
