NRCS "Prime Farmland" - Colorado Important Farmland Inventory pH error <br />United States Department of Agriculture <br />4NRCS <br />Natural Resources Conservattoo Service <br />Jim Boyd. Resource Comervatliontst Itm.boyd@co.usda.gov <br />P O. Box 29 970- 327- 4245 - OFFICE <br />Norwood, CO 81423 970. 327.4247 "FAX <br />March 4, 20 10 <br />Division of Reclamation, Mining and Safety <br />Department of Natural Resources <br />101 South 3` Street, Suite 301 <br />Grand Junction" CO 81501 <br />Dear Concerned Parties, <br />Accompanying this letter arc documents related to "Prime Farmland" determination for lands <br />within the New Horizon Mine, Western Fuels- Colorado, mine permit area. In particular, I would <br />like to address a letter written March 29, 1996 by Fortner MRCS Resource Conservationist Mr. <br />Dean Stindt, to the letter submitted to Western Fuels - Colorado, Mr, Stindt made a negative <br />determination regarding the presence of Prime Farmland on Garvey faros. property planned for <br />future coal mining. tie was assisted by soil scientist Mr. Jim Irvine, Intermountain Resource <br />Inventories Inc., who was hired by New Horizon Mine to complete an Order I Soil Survey t'or <br />the mine permit area, <br />Mr. Stindt stated in paragraph two of his letter that "irrigated sods with bedrock within 40 inches <br />of the surface and soil horizons that have a pH higher than 7.4 are considered as having high <br />conductivity and therefore are not prime." In regards to the soil observed on the Garvey <br />property, since both of these criteria were met, the soils were considered not Prime Farmland by <br />Mr. Stindt in his letter <br />Mr. Stindt and Mr. Irvine were relying upon a United States Department of Agriculture, Soil <br />Conservation Service document in circulation at that time titled "Colorado Important Farmland <br />Inventory," which indeed established the above criteria for prime farmland desigtnation on page 3 <br />of the document. Unfortunately, the pi I limit of 7.4 was an error in the document and should <br />have read 8.4 instead. This mistake in the Colorado Important Farmland Inventory document is <br />addressed more fully in a letter written by Dave-. Dearstync, MRCS Soil Scientist, dated February <br />It. 2408, and enclosed. <br />Regardless of the mistake described above, which has since been corrected, the sail designation <br />of not Prime Farmland for the Garvey Bros, property was most likely correct since the soils were <br />less than 40 inches in depth, and therefore may not have met the water holding capacity criteria <br />established for Prime Farmland designation. It is unfortunate if the soil pH limit of 7.4, an error, <br />referred to in the Colorado Important Farmland Inventory and referenced in the Garvey Bros, <br />determination, was used in subsequent determinations of Prime Farmland for other properties <br />mined within the New Horizon Mine permit area <br />The Natueal a„&,„, Gwr&vrvalbn 8orvrta %arks rn ganneriMo %Mh the Amernan Pantslp •_.._._...�._.._. .. - . <br />to currswwu and sustain natural rosoutcos on privala land& Air Equal Oppwtundy Pj amWj and EmpkWr <br />Friday, March 05, 2010.max <br />
