PUBLIC NOTICE i US Army Corps Application: 199880109 of Engineers Applicant: Andesite Rock Company Omaha District Waterway: Wetlands Issue Date: March 11, 1998 Expiration Date: April 10, 1998 REPLY TO: Tri-Lakes Project Office 9307 Colorado State Hwy. 121 30 DAY NOTICE Littleton, CO 80123-6901 JOINT PUBLIC NOTICE FOR PERMIT APPLICATION SUBMITTED TO U.S . ARMY CORPS OF ENGINEERS AND COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT The District Engineer, U. S. Army Engineer District, Omaha, Nebraska is evaluating a Department of the Army permit application from Andesite Rock Company, 9065 Quince Street, Henderson, Colorado 80640 . Permits are issued under Section 404 of the Clean Water Act which regulates the discharge of dredged or fill material in the nation's waters. Andesite Rock Company is requesting authorization to establish a gravel mining operation in Section 10, Township 2 North, Range 68 West, Weld County, Colorado. Andesite Rock Company is planning to mine aggregate from 183 acres of the 240 acres Camenisch Resource Gravel Pit. In January 1998, Andesite Rock Company applied for a Nationwide Authorization for two road crossings. This authorization was granted because the two road crossings required impacting 0. 064 acres of wetlands. The mining activity will impact an additional 0 . 5 acres. Andesite Rock Company has agreed to mitigate both impacts (0 .564 acres) during the mining operation. Camenisch mine will operate year-round, using dry-pit mining methods in five identified phases (1A, 1B, lc, 2, and 3) . It expects to excavate 10-15 acres per year removing approximately 400, 000 tons of aggregate annually. The expected mining period for this site is 8-14 years with reclamation taking approximately 2 additional years . Temporary structures include a wash plant, concrete plant and an asphalt plant to be located initially in the east-central area of Phase 1C (see maps for infrastructure locations) . Set backs from Idaho Creek and Rural Ditch will be approximately 50 feet. Idaho Creek will be maintained by the mining operation pumping pit water from the pit into the Creek. The applicant chose to go through an individual permit application review in- lieu-of waiting for the Nationwide changes to take place. The purpose of the project is to remove the necessary sand and gravel to mix with concrete and asphalt for the construction of roads and buildings. The original mining plan called for impacting Idaho Creek and re-aligning it once the mining was completed. The applicant revised the plan to avoid the creek and approximately 5 acres of adjacent wetlands. However, mining will impact both sides of the creek to include isolated wetlands. Approximately 0.564 acres of wetlands will be replaced near the northern edge of Phase 1B, enhancing the existing wetland by the end of the 1998 growing season. (see wetland map exhibit) Wetland mitigation will replace the wetland impacts to wetlands #7 and #8 as identified in the wetland delineation and the two road crossings of Idaho Creek permitted by Nationwide 14. Impacts to Idaho Creek will be avoided except for the two road crossings. Upon completion of the mining operation three lakes with the potential for additional wetland establishment will remain. Avoiding all the wetlands within the proposed mining boundaries was reviewed but not accepted. Most of the site wetlands are located in the western section (phase 1) making it difficult to avoid all wetlands. MITIGATION PLAN: Wetland #7 is identified as a drainage from a non-vegetated pond to Idaho Creek and wetland #8 is a salt-encrusted low lying swale. Wetland mitigation will replace the 0.564 acres of wetlands consisting of the small pond and drainage that will be removed at the northern edge of Phase 1A. The mitigation plan is to enlarge an existing wetland associated with Idaho Creek, along the northern edge of the mining permit boundary(phase 1B) . The mitigation site will be graded to an elevation consistent with the existing wetland. Wetland soils from the two areas lost to mining will be used to begin the replacement planting. Approximately 4-6 inches of root zone topsoil from the wetlands identified to be impacted will be carefully scraped off and spread evenly in the new wetland mitigation area. Mitigation areas will be protected from livestock grazing until the Corps accepts the mitigation. The US Fish & Wildlife Service has reviewed and accepted surveys for Spiranthes diluvialis and Zapus hudsonius preblei. Alternatives to mining this site were reviewed prior to applying for a department of the Army Permit. Those alternatives included shutting down the mining operation, avoiding all the wetlands within the mining area, and mining a different site. Because the aggregate is in demand for development closing up shop was not acceptable. Avoiding all the wetland is not acceptable because of the location of two particular isolated wetlands and the need for road crossings. Other locations were reviewed, however, they required impacting more wetlands than the proposed site, the property was sold to another mining company, or the property was not available for mining. Therefor, the proposed alternative as described in this public notice was concluded to be the most acceptable. The Colorado Department of Public Health and Environment, WQCD-GWPS-B2, 4300 Cherry Creek Drive South, Denver, Colorado 80222-1530, will review the proposed project for state certification in accordance with the provisions of Section 401 of the Clean Water Act. The certification, if issued, will express the State's opinion that the operations undertaken by the applicant will not result in a violation of applicable water quality standards. The Colorado Department of Public Health and Environment hereby incorporates this public notice as its own public notice and procedures by reference thereto. The Colorado Department of Public Health and Environment also reviews each project with respect to the antidegradation provisions in state regulations. For the project which is the subject of this public notice the Colorado Department of Public Health and Environment has preliminarily determined that this project is not located on waters that require an antidegradation review. For further information regarding antidegradation provisions, please contact Mr. John Farrow, telephone (303) 692-3575, at the Colorado Water Quality Control Division. Pursuant to the Endangered Species Act, the proposed project is being reviewed for impacts to threatened or endangered species and their critical 2 habitat. Our preliminary review indicates there will be no affect, because no such species are known to utilize the project area. The Omaha District will comply with the National Historic Preservation Act of 1966 and 36 CFR 800. We have checked the National Register of Historic Places and "its current supplements", and no property listed in the Register or proposed for listing is located in the permit area. This is the extent of our knowledge about historic properties in the permit area at this time. However, we will evaluate input by the State Historic Preservation Officer and the public in response to this public notice, and we may conduct or require a reconnaissance survey of the permit area or check for unknown historic properties, if warranted. The decision whether to issue a permit will be based on an evaluation of the probable impacts including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits which reasonably may be expected to accrue from the proposal must be balanced against the reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, wetlands, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership and, in general, the needs and welfare of the people. In addition, the evaluation of the impact of the work on the public interest will include application of the guidelines promulgated by the Administrator, Environmental Protection Agency, under authority of Section 404 (b) of the Clean Water Act (40 C.F.R. Part 230) . The Corps of Engineers is soliciting written comments from the public; Federal, state and local agencies and officials; Indian Tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Comments, both favorable and unfavorable, will be accepted, made a part of the record and will receive full consideration in subsequent actions on this application. Any agency or individual having an objection to the work should identify it as an objection with clear and specific reasons. All replies to the public notice should be sent to the U. S. Army Corps of Engineers, Tri-Lakes Project Office, 9307 Colorado State Highway 121, Littleton, Colorado 80123-6901. For additional information please contact Mr. Rex Fletcher at (303) 979-4120. The District Engineer will consider requests for holding a public hearing, for the purpose of gathering additional information. Before the expiration date of this notice, anyone may request, in writing, that a public hearing be held. Requests for a public hearing should state specifically the reasons for holding a public hearing, and what additional information would be obtained. Should the District Engineer decide that additional information is required and a public hearing should be held, interested parties will be notified of the date, time and location. Comments received after the close of business on the expiration date of this public notice will not be considered. 3 1 F !
