Existing Site Conditions
The 3M Pittsboro Quarry Extension site is located in the Piedmont physiographic region of North Carolina. Mining operations began in 2002 and have remained active through the present. The project area encompasses 860 acres of land, within which 176 acres are proposed to be excavated to recover andesite ore. Another 225 acres, wholly located in uplands, are proposed as an extension of the excavated material stockpile. The remaining 469 acres would remain undisturbed. The existing developed portions of the 2,200-acre property occupy 495 acres and include the 153 acre pit open quarry operated for 3M by Luck Stone, Inc., a crusher facility and work-in-process stockpile, a 3M roofing granules plant, a Luck Stone, Inc. quarry office and maintenance facilities; a 180 acre excavated materials stockpile; and stormwater management infrastructure.
Both the quarry and stockpile extension areas contain planted pine timber stands in various stages of growth, hardwood copses and clear-cut forests that are regenerating. Numerous maintained service roads are present on both tracts. The local landscape typifies the Piedmont physiographic region with low dissected ridges. Small wetlands intersperse both summits and depressions within the proposed extension areas. Throughout the proposed extension areas, exposed ground surfaces are rocky and outcrops of boulders are common. The water resources on the property include 22,857 linear feet of unnamed tributaries to Stinking Creek and Robeson Creek, of which 5,505 feet are perennial. Elevations on the site range from 380 to 511 feet above mean sea level. The Soil Survey of Chatham County, North Carolina (NRCS, 2006) shows the quarry and stockpile extension areas are underlain by Type B soils which have a moderate infiltration rate when thoroughly wet and are moderately well drained. The hydrologic regime is driven by rainfall runoff. The riparian areas along the three intermittent streams within the quarry extension area are dominated by pine trees in various stages of development and mature oak-hickory forested areas. The understory vegetation for the pine trees includes sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), American holly (Ilex opaca), dogwood (Cornus florida), southern red oak (Quercus falcata), black oak (Quercus velutina), winged elm (Ulmus alata), and black cherry (Prunus serotina) with greenbriar (Smilax rotundifolia), blackberry (Rubus spp.), and honeysuckle (Lonicera japonica). Understory for the oak-hickory forests include dogwood, American holly, sourwood (Oxydendron arboreum), redbud (Cercis canadensis), greenbriar, Christmas fern (Polystichum acrosticoides), rattlesnake plantain

(Goodyeara pubescens), heartleaf (Hexastylis sp.), ebony spleenwort (Asplenium platyneuron), and spotted wintergreen (Chimaphila maculata).
Wetlands and streams on the site are piedmont headwater systems that flow to Rocky Branch and Stinking Creek which flows to the Deep River and Jordan Lake respectively in the Cape Fear River. The tributary within the site have a best usage classification of WS-IV. WS-IV waters are used as sources of water supply for drinking, culinary, or food processing purposes.
Applicant’s Stated Purpose
The applicant’s stated purpose is to extend the boundaries of the existing quarry and corresponding excavated materials stockpile to extract the remaining proven onsite reserves in order to provide 3M and Luck Stone with an uninterrupted supply of andesite and metavolcanic minerals needed to supply the asphalt shingle industry in the southeastern United States and overseas, as well as to meet local aggregate needs.
Project Description
The project would extend the existing quarry to the north and would result in the construction of a berm along the south side of Charlie Brooks Road (SR 1969), which would also be a permanent overburden storage area. This berm would also be landscaped to provide a physical (public safety), visual and noise barrier buffer between the quarry and public roadways. These planned activities would impact a total of 2,533 linear feet of headwater streams and its associated riparian buffers, which would be excavated during the quarry extension.
In addition, 0.15 acre of jurisdictional wetlands and 0.6 acre of open waters would be impacted by the applicant’s preferred alternative. The applicant provided 55 alternative offsite mining options and five onsite mine plan alternatives in their permit submittal, including an upland only (“no action”) alternative. The applicant’s preferred alternative involves the expansion of the existing 153-acre quarry area to approximately 329 acres. The applicant also proposes to extend the existing 180 acre excavated materials stockpile to approximately 225 acres, none of which are subject to the Corps’ jurisdiction.
Avoidance and Minimization
The applicant provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment: While the applicant’s preferred alternative plan would directly impact more jurisdictional streams, wetlands, and open waters than three of the other alternatives provided (i.e., Alternatives 3A, 3B and 3C), the plan was reduced in scope to avoid 1,998 linear feet of streams, a 44 percent reduction; 0.35-acre of wetlands, a 70 percent reduction; and 1.6 acres of open waters, a 73 percent reduction. According to the applicant, all of the perennial streams, 85 percent of the intermittent streams, and 91 percent of the jurisdictional wetlands and open waters in the quarry and


Page 4
stockpile extension areas would be avoided. Over 99.5 percent of the physical disturbance would occur in uplands.
The applicant’s existing shingle granule manufacturing process utilizes reclaimed water from the Town of Pittsboro wastewater treatment facility as the process water make-up supply and is equipped with a zero-discharge industrial wastewater treatment system. This process design reduces the nutrient loading to the B. Everett Jordan Lake federal project by 3,727 and 453 lbs./yr. of nitrogen and phosphorus, respectively, which benefits the receiving aquatic environment that has been designated as impaired by nutrients under Section 303 of the federal CWA.
Compensatory Mitigation
The applicant’s proposed mitigation includes purchase of mitigation bank credits from an approved bank operated by Restoration Systems, LLC (RS); purchase of in-lieu-fee credits from the North Carolina Division of Mitigation Services; and preservation of certain onsite streams and riparian buffers. The applicant provided supporting documentation in letters dated March 17, 2017, and April 10, 2017, from RS and March 20, 2017, from DMS stating they are willing to accept compensatory mitigation payment for up to 2,533 linear feet of stream impacts and 0.15 acre of wetland impacts within the Haw River Basin (03030002). In addition, as required by DEQ, the applicant will purchase up to 292,433 ft2 of riparian buffer credits from RS and DMS. Further, 3M is proposing to place 11,882 linear feet of intermittent and perennial stream under conservation easements to protect them from future development.
Essential Fish Habitat
Pursuant to the Magnuson-Stevens Fishery Conservation and Management Act, this Public Notice initiates the Essential Fish Habitat (EFH) consultation requirements. The Corps’ initial determination is that the proposed project may affect, but not likely to adversely affect EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service.
Cultural Resources
Pursuant to Section 106 of the National Historic Preservation Act of 1966, Appendix C of 33 CFR Part 325, and the 2005 Revised Interim Guidance for Implementing Appendix C, the District Engineer consulted district files and records and the latest published version of the National Register of Historic Places and initially determines that:
Should historic properties, or properties eligible for inclusion in the National Register, be present within the Corps’ permit area; the proposed activity requiring the DA permit (the undertaking) is a type of activity that will have no potential to cause an effect to an historic properties.
