proposed decision for PR -07 is not issued by August 28, 2015, TMI will <br />need to update this drainage design with another revision. <br />4.25 Prime Farmland <br />In the Trapper permit, Section 2.6 Part 2 page 2-344, is a letter from the USDA Soil <br />Conservation Service dated February 21, 1980. The letter concludes that prime farmlands do <br />not exist within the Trapper permit area because of a short growing season, lack of natural <br />precipitation and no irrigation or sub -irrigation. This letter was written in 1980 and the Trapper <br />Mine has expanded its permit boundary since that time. It is unclear from the permit if another <br />prime farmland determination has been completed. <br />A Web Soil Survey(websoilsurvey.sc.egov.usda.gov) was conducted by the Division to verify <br />if soil types that could be considered prime farmland exist at the Trapper Mine. The current <br />permit boundary shapefile was used in the Web Soil Survey to create an area of interest (AOI) <br />which describes the soil types within the permit boundary. One soil type was identified as <br />having the possibility of being prime farmland if irrigated. The soil is map unit symbol 10, <br />battlement fine sandy loam with 0 to 3% slopes. This soil type exists in two locations within <br />the Trapper Permit for a combined area of 17.8 acres. <br />• Please update the prime farmland determination and include a <br />discussion about the two areas of battlement fine sandy load with 0 to <br />3% slopes that are found within the permit area. <br />Trapper Midterm 2015 Findings TNL_2.docx Page 9 <br />
