The Corps evaluates this application and decides whether to issue, conditionally issue, or deny the proposed work pursuant to applicable procedures of the following Statutory Authorities:

Section 404 of the Clean Water Act (33 U.S.C. 1344)


Location Description: The project site is located immediately south of the existing Salem Stone Quarry which is situated west of High Point Road, east of Hastings Road, south of US Hwy 311, near the Town of Kernersville, in Forsyth County, North Carolina. The address for the Salem Stone Quarry is 4572 High Point Road, Kernersville, North Carolina 27284.

Project Area (acres): 96 acres

Nearest Town: Kernersville

Nearest Waterway: Spurgeon Creek

River Basin: Upper Pee Dee

Latitude and Longitude: 36.0262382 N, -80.1103207 W

Existing Site Conditions

The Salem Stone Quarry mine expansion site is located in the piedmont physiographic region of North Carolina. Forests within the proposed project area are dominated by red maple (Acer rubrum) and sweetgum (Liquidambar styraciflua) with an understory that consists of Chinese privet (Ligustrum sinense) and Japanese honeysuckle (Lonicera japonica). Two jurisdictional streams are located within the project area’s boundaries and both are unnamed tributaries of Spurgeon Creek. No wetlands exist within the site. According to the Soil Survey of Forsyth County, on-site soils consist mostly of Fairview and Pacolet soil series. The eastern portion of the project site is located within the 100-year floodplain of Spurgeon Creek, a tributary of Abbotts Creek. The property that makes up the Salem Stone Quarry and the expansion site was acquired by Martin Marietta in 1987, and the quarry has been in operation since 1989. Land use in the vicinity of the existing quarry operation consists of low density residential neighborhoods and open pasture farm land.

Applicant’s Stated Purpose

The applicant’s stated purpose of the proposed project is to cost-effectively expand the existing crushed stone quarry operation at Salem Stone Quarry into known suitable stone reserves in order to serve market demand for crushed stone in the geographic area that encompasses Forsyth, Stokes, Guilford, Davidson, Davie and Yadkin counties.

Project Description

On November 6, 2007, the applicant received a DA permit to expand the Salem Stone Quarry into an approximately 106 acre tract of land located immediately south of the existing quarry, but the permit expired on December 31, 2012, before the work was completed. The permit authorized impacts to 3,527 lf of jurisdictional streams. Under the permit, 2,872 lf of stream impact required mitigation and 655 lf of stream impacts did not require mitigation due to the minimal aquatic function observed in the stream.

The applicant has indicated that only 10 acres (approximately 1,640 lf of stream impacts) of the proposed expansion area was completed under the permit before it expired. The applicant is requesting a DA permit to re-authorize impacts to the remaining 1,887 lf of stream that exists within the proposed mine expansion area so that the proposed project may be completed.

The applicant has already satisfied mitigation requirements for permanent impacts to all jurisdictional waters that were authorized by the original permit, including the impacts that have not yet occurred and are the subject of this application.

Avoidance and Minimization

The applicant provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:

The applicant has nearly exhausted the stone reserves at its Salem Quarry in Forsyth County, North Carolina. In order to cost-effectively mine additional stone reserves which have been identified on site and to continue quarry operations to meet area demand for construction aggregates, the applicant proposes to expand its existing mining operations to the south, which would allow access to an estimated 85 million tons of stone reserves (estimated to provide approximately 125 years of product supply at current mining rates). The existing quarry operation is constrained to the north by US 311, to the east by High Point Road, and to the west by the main branch of Spurgeon Creek. No off-site alternatives for the proposed project would meet the project purpose and need, which is defined as cost-effective expansion of the existing facility to the original permitted boundaries to serve the market area. Furthermore, because the proposed expansion is dependent on the existing facility, any off-site alternative would be financially unfeasible for the applicant and would likely result in increased impacts to jurisdictional waters of the U.S. due to the size of the site required.

The applicant studied three alternatives on their preferred project site. One alternative that was considered was to mine around the two existing intermittent stream channels on the site. However, due to the close proximity of the stream channels to each other and the amount of the existing overburden (material above the rock reserves) on the site, it was determined that adequate reserves would not be achieved with this alternative. The constraints of the stream channels would significantly reduce the available stone for mining Therefore, this alternative is not feasible for this location. Another alternative that was considered was to relocate the two intermittent stream channels on the site. However, due to the topographical challenges on the site, the relocated stream channels would have to be placed in 300 foot wide open cuts to achieve the necessary grade for natural stream channel slopes. This would result in an unstable and unnatural conveyance of stream channel flows plus would greatly impact the available access to the stone reserves on the 106 acre tract.

The applicant proposes that by allowing the water within the two tributaries to enter the pit of the proposed quarry expansion, the quality of the water entering Spurgeon Creek from these impacted tributaries would be improved. The onsite treatment and stormwater control resulting from the quarry operations could be a net benefit to the water quality of Spurgeon Creek as the existing stream channels are highly erosive. This alternative maximizes the amount of the available stone in a concentrated area while avoiding and minimizing impacts to the main branch of Spurgeon Creek.

Compensatory Mitigation

The applicant offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment: Mitigation requirements for all impacts authorized under the original permit have been satisfied, including those that have not yet occurred and are requested in this application. The applicant provided supporting documentation in a letter, dated November 29, 2007, from the North Carolina Ecosystem Enhancement Program (NCEEP) that indicates that compensatory mitigation requirements associated with the previously authorized activity have been satisfied.

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 would not effect 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:

No historic properties, nor properties eligible for inclusion in the National Register, are present within the Corps’ permit area; therefore, there will be no historic

The District Engineer’s final eligibility and effect determination will be based upon coordination with the SHPO and/or THPO, as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on historic properties within the Corps-indentified permit area.

Endangered Species

Pursuant to the Endangered Species Act of 1973, the Corps reviewed the project area, examined all information provided by the applicant and consulted the latest North Carolina Natural Heritage Database. Based on available information:

The Corps is not aware of the presence of species listed as threatened or endangered or their critical habitat formally designated pursuant to the Endangered Species Act of 1973 (ESA) within the project area. The Corps will make a final determination on the effects of the proposed project upon additional review of the project and completion of any necessary biological assessment and/or consultation with the U.S. Fish and Wildlife Service and/or National Marine Fisheries Service.
