Corley Comment #4 <br />In an October 29, 2015 email, Dr. Corley expressed concerns about weeds at the mine site, in particular <br />mullein, cheat grass, bind weed, cranes bill, and knapweed. He also reiterated his concerns about debris <br />at the Monarch Fan, the spring in the Magpie Diversion, and new subsidence cracks. <br />Response to Comment #4 <br />The Division did not see any new subsidence cracks in the areas affiliated with SL -03 during the <br />inspection or subsequent to the inspection. The other issues were addressed in previous email <br />communications. <br />Corley Comment #5 <br />In a November 24, 2015 email, Dr. Corley asked if the Newlin Creek topsoil stockpile had been <br />officially designated as an SAE. <br />Response to Comment #5 <br />The Newlin Creek topsoil stockpile has been officially designated as an SAE (see Map 30 and Appendix <br />19 in the PAP). <br />Corley Comment #6 <br />In a January 15, 2016 email, Dr. Corley suggested that the south inlet culvert to Pond 5 was never <br />approved by the Division and that holes in the metal of the culvert are a "defect." <br />Response to Comment #6 <br />The south inlet culvert to Pond 5 is approved by the Division and the structure is shown on an approved <br />map (Map 18). The holes in the culvert have been repaired. <br />Corley Comment #7 <br />Also in the January 15, 2016 email, Dr. Corley noted that the side tunnel off of the truck tunnel is not <br />shown on any maps in the permit application package (PAP). <br />Response to Comment #7 <br />The side tunnel off of the truck tunnel does not need to be shown on any maps in the PAP as it is an <br />underground structure. <br />Comment #8 <br />In a January 21, 2016 email, Dr. Corley identified problems with the sediment demonstration in the SL - <br />03 application. <br />Response to Comment #8 <br />The Division finds that EFCI produced a sufficient sediment demonstration in the SL -03 application and <br />subsequent adequacy responses. <br />Corley Comment #9 <br />In a January 23, 2015 email, Dr. Corley stated that he found a well casing in the portal area, that there is <br />sediment in the south inlet culvert to Pond 5, and that there are bare areas with some erosion on the <br />Magpie Diversion berm. <br />Response to Comment #9 <br />EFCI found this to be a loose piece of pipe. They removed it on February 19, 2016. <br />Southfield Mine SL -03 Page 5 of 21 February 23, 2016 <br />
