McArdle Reclamation Specialists Subject: Boulder County Use Permit Criteria for Limited Impact Sandstone Quarrying in. Steamboat and Stone Canyons, Sections 5, 6, and 7, Township 3 North, Range 70 West Gentlemen: The Boulder County Zoning Resolution was amended on 9 October 1980 to exempt open mining operations from the lengthy Special Use Review process if such operations disturb less than ten acres of land and extract less .than 70,000 tons of rock. Since the quarries operating in the above sections investigated on 15 January 1981 were determined to be open mining small acreages with tonnages below these maximum use-by-right levels, no public hearings are relevant , pefore the Planning Commission nor before the Board of County Commissioners for the release of a Special Use Permit. Limited impact mining, however, was determined to be in excess of 50 cubic yards of overburden and mineral including pits and haul roads which was sizable enough to be governed by the Boulder County Uniform Building Code, adopted in 1979. Chapter 70 of this code requires a grading and excavation permit be obtained which may be applied for at the Boulder County Land Use Department for the purposes of reviewing any adverse effects on public ways, drainages, neighboring properties or persons. The quarries required to apply for a grading permit include the Phillips Stone Company in the West Half of Section S, Township 3 North, Range 70 West; Ignacio Vasquez in the East Half of the Northeast Quarter of Section 6, Township 3 North, Range 70 West; Johnson and Berry in the Southeast Quarter of the Northwest Quarter of Section 7, Township 3 North, Range 70 West; Neil Sprague in the South Half of the Southeast Quarter of the Northeast Quarter of the Northwest Quarter and the North Half of the Northeast Quarter of the Southeast Quarter of the Northwest Quarter in Section 7, Township 3 North, Range 70 West; and the Monty Pearson quarry in the Northwest Quarter of the North Half of the Southwest Quarter and the East Half less parts sold in Section 7, Township 3 North, Range 70 West. Parcel owners who have mining structures or buildings constructed since 1961 without permits will .be required to obtain the necessary building permits along with the related grading permit.
