Mr. Dustin Czapla 2 <br /> CDRMS <br /> September 24, 2021 <br /> address this discrepancy and state the correct TSF area. The TSF description <br /> should be consistent with the TSF shown on maps in Exhibit C. <br /> Response <br /> The 4.6 acre stated in Exhibit D was in reference to an older design that called for a "Phase 2" <br /> TSF expansion. This reference was missed during editing. The actual TSF is about 2.5 acres, <br /> and references in Exhibit D, as well as other places in the permit will be appropriately edited. <br /> 4. Rule 6.4.5 Exhibit E — Reclamation Plan <br /> On page 5-1 of Exhibit E the application states that approximately 1,500 yds of <br /> topsoil is currently stockpiled on site. Please describe the Operator's plans to <br /> establish a vegetative cover over the stockpiled topsoil in order to prevent <br /> deterioration and to ensure it remains in a usable condition for reclamation <br /> pursuant to Rule 3.1.9 (1). <br /> Response <br /> We have recently added soil and alternative growth material to the topsoil pile and will generate <br /> more topsoil from Storm Water plan implementation. We will re-seed as necessary. <br /> 5. Rule 6.4.5 Exhibit E — Reclamation Plan <br /> On page 5-1 of Exhibit E the application states that the above existing 1,500 yds. <br /> topsoil stockpile will be used for reclamation of the entire affected area. On page 5- <br /> 5 the application states that the stockpile will be used to provide 4" cover over the <br /> TSF. Please clarify. <br /> Response <br /> The TSF is the only area that the topsoil/Suitable Plant Growth Material (SPGM)will be used. <br /> Post-reclamation, the roads and buildings will remain, and therefore will not require topsoil. <br /> 6. Rule 6.4.5 Exhibit E — Reclamation Plan <br /> On pages 5-4 and 5-5 of Exhibit E the application states that the TSF will be covered <br /> by 8" of embankment material, then 4" of topsoil and 4" of suitable plant growth <br /> material. <br /> Please provide a description of the "suitable plant growth material" that will be <br /> used. In order to establish the quality of suitable plant growth material, please <br /> sample and provide analysis to the Division. <br /> Additionally, please provide to the Division the amount and stockpile location of <br /> this suitable plant growth material that is available at the site. <br /> Response <br /> The section should read "the TSF will be covered by 8"of embankment till material, then 4"of <br /> topsoil and/or 4"of suitable plant growth material' resulting in a total of 12 inches (8 inches of till <br /> and 4 inches of topsoil/SPGM). <br /> See response number 13 for a description of suitable plant growth material. <br /> Suitable plant growth material to be used for reclamation was stockpiled from TSF embankment <br /> construction. Upon commencing final reclamation, testing of suitable plant growth material will <br /> be appropriately analyzed as described in response to question 23. <br /> The SPGM pile is located on the northeast corner of the TSF and contains approximately <br /> 2500yd3. <br />
