Trapper Mining Inc., TR -115 <br />Page 16 <br />4.05.3(1) <br />Table 4.8-3 provides the diversion ditch sizing requirements. The following diversion <br />ditches do not include all of the sizing information: East Middle Flume A98-3 and East <br />Flume. This table will need to be updated to provide sizing information for these <br />diversion ditches. <br />'11'rapper Response: A full response tea this conwzent will be provided with a fiaa^thecanzin,, <br />ethnical Revision includin,, any new rrlZdaies to the sing fbce watersheds cf'the site. he iable <br />needs fitriher rrldaies, includin,, renzovin,, diversion Aches periainin,, to Phase III areas. %?(,Is/ <br />1,7rr)ze diversion Ach has never been constructed thus no designs have been ,,eneraied for it. <br />4.05.4(1) <br />The ephemeral drainages at the mine are reconstructed through the reclamation <br />process and their design is being updated with PR -07.

The letter concludes that prime <br />farmlands do not exist within the Trapper permit area because of a short growing season, lack of <br />natural precipitation and no irrigation or sub -irrigation. This letter was written in 1980 and the <br />Trapper Mine has expanded its permit boundary since that time. It is unclear from the permit if <br />another prime farmland determination has been completed. A Web Soil Survey <br />(websoilsurvey.sc.egov.usda.gov) was conducted by the Division to verify if soil types that could <br />be considered prime farmland exist at the Trapper Mine. The current permit boundary shapefile <br />was used in the Web Soil Survey to create an area of interest (AOI) which describes the soil types <br />within the permit boundary. One soil type was identified as having the possibility of being prime <br />farmland if irrigated. The soil is map unit symbol 10, battlement fine sandy loam with 0 to 3% <br />slopes. This soil type exists in two locations within the Trapper Permit for a combined area of <br />17.8 acres. <br />Please update the prime farmland determination and include a discussion about the two <br />areas of battlement fine sandy load with 0 to 3% slopes that are found within the permit <br />area. <br />1 rapper Re S.'
