Name of Addressee <br />Page 7 <br />Date <br />discuss the specific methods used to strip Topsoil. In accordance with Rule 2.05.3(5), please <br />update this section of the permit to discuss topsoil stripping methods. <br />36. Rule 2.05.3(5) requires the permit narrative to specify the depth of material to be salvaged from <br />all disturbed areas. This section of the permit only specifies the depth of soil removal from some <br />of the disturbed areas but not all of them. At this point, for the current disturbed area, the topsoil <br />is already stripped and placed in topsoil stockpiles listed on Table 49A of the permit and depicted <br />on Map 29 so the depth stripped is irrelevant. Map 17 shows the pre -mine topsoil thickness for <br />the permit area based on the soil mapping unit. This map should be consulted to ascertain the <br />average topsoil depth to be stripped from future disturbed areas. Please update section 2.05.3(5) <br />of the permit to discuss how the depth of topsoil to be stripped at a site is determined based on the <br />soils information provided in Rule 2.04.9. <br />Rule: 2.05.3 (4)(a) -(d) <br />37. In section 2.05-76.1 through 2.05-84, there seems to be duplicate information and outdated pages. <br />Please address the following: <br />a. Please clarify Exhibit 8C (1). Was this structure ever built? <br />b. In the narrative (section 2.05-76.1 through 2.05-84) for the following ponds, please insert <br />the Exhibit number and information as to the design precipitation event (for example: <br />I Oyr/24 hr. or 25yr/24hr): <br />i. <br />Pond B <br />ii. <br />Pond C <br />iii. <br />Pond D <br />iv. <br />Pond E <br />v. <br />Pond F <br />vi. <br />Pond G <br />vii. <br />Pond T <br />viii. <br />FCB Treatment Facility <br />38. Section 2.05-76-1 regarding Pond D states that the spillway was relocated. Please either provide <br />the exhibit number for updated as built designs for the relocated spillway, or provide a set of <br />updated as builts reflecting the new spillway location. <br />39. Pond F Exhibit 8I includes a list of As Built Specifications. Exhibit 8P in the permit entitled: <br />Plate 1, Sediment Ponds, Energy Mines No.I and No. 2 and Eckman Park includes a table entitled <br />Pond Schedule. The Pond Schedule table and Exhibit 8I As Built Specification values differ from <br />each other. Please address the following: <br />a. Please check Exhibit 8I, as built specifications for Pond F against the Pond Schedule in <br />Exhibit 8I and submit a new Pond Schedule table addressing the following values: <br />i. Sediment Storage Volume <br />ii. OSM Height <br />
