vegetation information found within Sections 2.04.9 and 2.04.10, respectively, of the New <br />Horizon Mine permit application. <br />The sediment storage is calculated using the Modified Universal Soil Loss Equation (MUSLE) <br />contained within the SEDCAD computer program. The spillways are designed using the spillway <br />routing subroutine program in the SEDCAD computer program and applicable engineering <br />procedures as described in the text of each sedimentation pond's design report. All sediment <br />ponds are designed and located to capture surface runoff from upstream disturbance areas and to <br />comply with all applicable State and Federal regulations. <br />With regards to Pond 007, it is currently overdesigned for its watershed area. Originally, the <br />watershed area was calculated to be approximately 514 acres (see Map 2.05.3(3)-2-2), and the <br />pond was built in 1995 using that value. Pond 008 was permitted in 1999 and built in 2000 in the <br />western portion of the Pond 007 watershed. The Pond 008 drainage area directly subtracts from <br />the original Pond 007 watershed, so the Pond 007 watershed has been reduced to about 423 <br />acres. <br />Section 2.05.3(3) Page 7 April 2017 (MR -104) <br />
