EXHIBIT D <br /> Mining Plan <br /> Korwell Land Holdings, LLC (Korwell) owns a 162-acre parcel in Weld County,Colorado(Site). The Site <br /> consists of 132 acres of active agricultural land under a center pivot irrigation system, and 30 acres of <br /> "dry corners" outside of the center pivot irrigation range.There are active oil and gas operations in the <br /> northwest dry corner of the parcel.There is also one(1) single vertical oil well in the center of the <br /> northeast quarter along with a production facility in the NE/4 dry corner.This well and facility are <br /> scheduled to be plugged and abandoned and reclaimed by Chevron in the winter of 2022-23.This well <br /> site will be plugged and abandoned before topsoil mining operations begin in the northeast quarter. <br /> Korwell proposes to mine approximately 372,679 tons (approximately 248,453 cubic yards)of topsoil <br /> from the 132 acres under the existing center irrigation pivot. Korwell is the landowner and operator of <br /> the mining activity. <br /> Korwell is proposing to mine the upper 50 to 80 percent of topsoil from the irrigated portion of existing <br /> agricultural land in order to provide topsoil for reclamation of third-party development sites. The <br /> topsoil on Site has been measured between 14-18 inches in depth.The operator will extract <br /> approximately 12-14 inches of topsoil, leaving at least 3-6 inches on Site for reclamation purposes. <br /> Korwell will dig test holes on approximately a 500'x 500'grid to verify depths and ensure adequate top <br /> soil remains.The goal to remove a total of 372,679 tons of topsoil will occur in four phases over the <br /> course of four to six years after obtaining the Construction Material Regular 112 Operation Permit. <br /> Mining Limits <br /> Korwell Land Holdings, LLC proposes a permit boundary that encompasses the entirety of the 162-acre <br /> property, described as The Southwest Quarter of Section 25,Township 4 North, Range 66 West of the <br /> 6th P.M., County of Weld, State of Colorado. The mining limits are established generally as the portion of <br /> the site irrigated by the center pivot. Within that irrigated area,the mining limits are further restricted <br /> by setbacks from property lines as well as existing easements and structures. The resulting mining area <br /> is approximately 129.2 acres. <br /> Products <br /> Topsoil will be the only product produced by the Korwell Soils Mine. The topsoil will be taken off-site for <br /> use at various oil and gas project locations. <br /> Mining Methods <br /> The topsoil will be dry mined and will not result in the need for any dewatering. Mining will be done <br /> with a variety of earth-moving equipment, including dozers, loaders, and scrapers. Watering trucks will <br /> be employed as needed to mitigate wind erosion of the exposed soil. Mined topsoil will be stockpiled <br /> near the single access point along the northwest property line. The topsoil will be loaded onto trucks for <br /> transport to the end user. <br /> BASELINE Korwell Land Holdings, LLC <br /> __ Korwell Soils Mine <br /> Plenmag�.5 e7.og:npmee,fng u <br /> DRMS 112 Permit Application <br /> 1 <br />
