Please review and respond to the adequacy review letter provided by Rob Zuber, DRMS (see enclosed letter, dated July 26, 2021). Questions posed by Rob Zuber are shown in blue italics font with Young Ranch Resource responses shown in black text. 1. There appears to be a discrepancy on Figure 5 (page D-12). Per this figure, the WRL will have a rock surface, but it also will be planted with a native seed mix. The applicant needs to provide more detail on where the rock cap will be located and where the topsoil and plants will be placed in relation to the rock. All WRL slopes will be capped with coarsely blasted rock that will then be seeded. The coarsely blasted rock will provide microclimates to enhance reclamation success and to better mimic adjacent landforms. Additionally, coarse blasted rock will serve to provide additional slope stabilization relative to the minimal vegetative protection required by the Division. Refer to Figure 6 of the permit narrative for an example image of volunteer vegetation following CCP construction that will be mimicked to reclaim the much more shallowly sloped WRL. 2. Regarding page D-13, the applicant should confirm that the height of the berm is 9 feet or less. There could be an error and this dimension should be 9 feet or more. The height of the WRL berm will be <_9-feet in height. 3. On page D-14 more detail is needed regarding the culvert mentioned in the first paragraph. Calculations for the size of the culvert should be provided, or the application should include an explanation as to why this calculation is not needed. Additional information in text and on map G-2 should answer the following questions. What happens to the water that will flow through this culvert? Will it be diverted offsite?How will the WRL be protected from these flows? December 2021 30 Lewicki&Associates
