I, Transit Mix Concrete Co. EXHIBIT I- Soils Information (Rule 6.4.9) 180) Comment: The text states that topsoil availability within the predominant map unit(MU 77)in the proposed mining area is limited and ranges from 0-6 inches. The proposed reclamation plan includes replacing topsoil on disturbed land at an average depth of 6 inches. Therefore,does the applicant anticipate the need to import topsoil for reclamation (if less than 6 inches is available to salvage)? If so, the applicant should include this proposed activity in Exhibit E. Otherwise, any changes to the reclamation plan may be considered at a later date through the revision process. Response: The Exhibit I text has been revised to address this comment. Transit Mix does not anticipate the need to import topsoil,but a Technical Revision will be submitted if additional topsoil is necessary. EXHIBIT J-Vegetation Information(Rule 6.4.10) Federally Listed Plant Species 181) Comment: The text states that the proposed permit area is within the geographic range of the federally threatened Ute ladies'-tresses, a species of orchid. USFWS is considering requesting surveys be conducted for this species, and if necessary,the survey will be completed in summer 2016 in suitable habitat at the proposed access road crossing for Little Turkey Creek,the only area where disturbance could affect the plant. Please commit to providing the results of these surveys to the Division. Response: Transit Mix conducted a habitat assessment(not a plant survey)for endangered species and met with a USFWS biologist onsite. Regarding the possibility that Ute ladies' tresses,USFWS agreed that no suitable habitat exists,the species is not expected to occur,no plant survey will be needed,and that the project would not affect the species. These conclusions will be reported in the Biological Assessment being prepared for US Army Corps of Engineers to submit to USFWS to conduct Endangered Species Act consultation. The Exhibit J text has been revised to address this comment. Vegetation Community Descriptions 182) Comment: In some of the vegetation community descriptions (i.e., riparian woodland, mountain shrubland, grassland), some Colorado state-listed noxious weed species were identified, including: Dalmation toadflax, Common teasel, Canada thistle, Bull thistle, Common burdock, Common mullein, and Musk thistle. Please submit a weed management plan that includes measures for controlling particular species identified in this exhibit. Hitch Rack Ranch Quarry(M-2016-010) Response to Comments—July 14, 2016
