Colorado 434 Meadows Way <br /> Grand Junction, CO 81507 <br /> Vegetation (970) 261-1304 <br /> Management <br /> October 20, 2020 <br /> Submitted to: Concerning Property: <br /> Parkerson Construction,Inc. Valley Vista Gravel Pit <br /> 710 S 15th Street 128 32 Road <br /> Grand Junction,CO 81501 Grand Junction,CO 81503 <br /> Attention: Greg Monger-GM (970)242-4654 ,re�:r;r�arke�:�.ot�s.com <br /> The purpose of this letter is to address concerns brought to Parkerson Construction, Inc.by the Colorado <br /> Division of Reclamation,Mining and Safety (CDRMS)regarding the reclamation of Valley Vista Gravel <br /> Pit, (Permit#M-81-229)located in Mesa County, Colorado in order to comply with CDRMS standards. <br /> Colorado Vegetation Management, LLC (CVM),acting as the representative for Parkerson Construction, <br /> Inc. in this matter,annually treats the areas actively being mined for existing noxious weed species. <br /> Recently CVM conducted an evaluation of the existing vegetation on the entirety of the property where <br /> the Valley Vista Gravel Pit sits. The following noxious weed species were found to be on the property <br /> either in heavy infestations, or in smaller sporadic areas of infestation: Halogeton, cheat grass, Russian <br /> thistle, and one tamarisk. <br /> CVM and Parkerson Construction, Inc.has agreed upon a reclamation and noxious weed treatment plan <br /> that will continue for as long as the permit is held to meet the standards of the CDRMS. This property <br /> will be monitored monthly(April -August)for noxious weed species and treated as needed. <br /> The majority of the property will be spot treated with herbicides, only where needed,to kill existing <br /> noxious weed species,while at the same time preserving the native vegetation that has repopulated the <br /> property over the last several decades. These areas have healthy stands of rabbitbrush, salt brush, and <br /> native grasses that we do not want to disturb. <br /> The portion of the property where the most recent mining activity has taken place will be graded, <br /> dragged, and treated to prevent the emergence of those noxious weed species, and eventually re-seeded <br /> when it is appropriate to do so. Because there is no on-site water source and hauling water to the site will <br /> not be a cost-effective option,reseeding will be done at the optimal time, corresponding with the most <br /> forecast natural moisture. <br /> If any questions or concerns remain regarding the reclamation of Valley Vista Gravel Pit,please contact <br /> me at the email address below and they will be answered promptly. <br /> Colorado Department of AEriculture Commercial Pesticide Applicator I.D.#: 29133 <br /> Colorado Vegetation Management, LLC <br /> r�rrinr �-t <br /> President <br /> liimm u,coloradoi�egetationrnanagef_ <br /> (970)261-1304 <br />
