~ _ i -- , Rule 2.04.9(1)(c) - Soil Resource Information The information provided is a major improvement over the original information and will be suitable for determining the extent of the soil available for reclamation. However, for the purpose of a complete and comprehensive permit application with adequate baseline date and maps, the operator should provide a map which delineates the extent of the Ayon and Capulin soils. The map submitted uses range site descriptions which apparently correlate with the soil types. The Division believes it would be more appropriate to show the soil delineations with soil unit names attached instead of range site descriptions. Also, the SCS in Trinidad has informed the Division that the "Basalt Breaks" range site should be "Cobbly Foothills" instead. Therefore, on the soils map the "Basalt Breaks" alias "Cobbly Foothills" should be Ayon soil type and the "Loamy Plans" should be the Capulin soil type. The SCS also submitted additional description information concerning the soil type, and range sites which probably should be inserted into the permit as baseline information. Rule 2.04.10 The application does not contain adequate vegetation baseline data. In order to evaluate the success of revegetation efforts, the Division needs a baseline vegetation study which describes on-site plant communities in term of species composition, vegetative cover and productivity and woody plant density. Reference is made to data in Exhibit H. However, the species numbers in the text are not contained in Exhibit H. The production figures in the text do not agree with those in the exhibit. Review of this site specific information may precipitate further questions on the revegetation plan. Rule 2.05.3(4) The design presented for the permanent diversion of the Engelville Gulch was inadequate to handle the 100-year, 24-hour peak flow. The Division requests you submit an alternate design that will safely pass the 10-year, 24-hour event which will constitute a temporary diversion. Also the permanent diversion of Engelville Gulch will have to be removed from all narratives of the permit application. The statement on page 5 of Section 2.05.3(1) and (2) that "the sediment pond will be converted to a stock pond when all mining activities cease" should be revised to indicate compliance with Rule 4.05.6(12), i.e. ponds shall not be removed until the disturbed area is reclaimed and it is demonstrated to the Division that the requirements of 4.05.2(2) are met. For ponds proposed to remain as permanent structures, it must be demonstrated to the Division that the requirements of 4.05.9 are met. Though the calculations for the sizing of the sediment pond appear to be adequate there is still a lack of proper design and contour information with plan view. All drawings used to establish the requirements of 4.05.6(3) shall be included in the permit application.
