FINDING OF NO SIGNIFICANT EMPACT
Environmental Assessment for the McAlpine Creek Relief Sewer
Charlotte -Mecklenburg Utilities
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-1, et
seq.), an environmental assessment (EA) has been prepared for the construction of a gravity relief sewer
to serve the McAlpine, Six Mile, Four Mile, and Crooked Creek Basins in Mecklenburg County,
Governmental bodies with jurisdiction over the service area include Charlotte -Mecklenburg County, and
the Towns of Mint Hill and Matthews. The project consists of the following major elements: installation
of approximately 79,000 linear feet of sewer along McAlpine Creek, elimination of a force main and
purnp station at the Four Mile Creek confluence, and elimination of approximately 31 existing lateral
sewer aerial crossing of McAlpine Creek. The proposed relief sewer will convey wastewater to the
McAlpine Creek Wastewater Treatment Plant.
The project is necessary to 'reduce/eliminate wet -weather overflows in the existing system and to
accommodate predicted growth. Although adjacent to basins identified as having habitat suitable for the
Carolina Heelsplitter, a federally listed freshwater mussel, Charlotte Mecklenburg Utilities has no specific
plans to provide service to such areas via the project at present.
The "no -action" alternative was eliminated from consideration, since it would not be reasonable or
feasible given • the insufficient capacity , of the existing system, ongoing impacts of sanitary sewer
overflows, and anticipated growth in the service area. During the project preliminary design phase a
review of various alignment alternatives were reviewed to minimize construction impacts and maximize
project benefits. Detailed information about the project's alignment and configuration are contained
within the EA.
The project has been aligned taking into account associated engineering design requirements and the
avoidance and/or minimization of environmental constraints as well as cultural constraints. During
construction, an approved Sediment and Erosion Control Plan will be utilized to prevent exceedences of
the established turbidity water quality standard. Following completion of construction activities, the
project area will be restored. Efforts will be made to minimize the removal of trees from the project area.
Detailed discussion of the project's direct impacts and efforts to mitigate them are included in the EA.
Secondary and cumulative environmental impacts may result from the McAlpine Creek Relief Sewer
project. Mitigation for such impacts will be provided by various ordinances and land development
regulations implemented and enforced by the aforementioned local government jurisdictions. These
include, stormwater, floodplain management, and riparian buffer protection measures. All measures are
described in detail within the EA.
Based on the findings of the EA and on the impact avoidance/mitigation measures contained therein, the
Division of Water Quality has concluded that the proposed project will not result in significant impacts to
the environment. This EA and Finding of No Significant Impact are prerequisites for the issuance of
Division of Water Quality permits necessary for the project's construction.. An Environmental Impact
Statement will not be prepared for this project. This FONSI completes the environmental review record,
which is available for inspection at the State Clearinghouse.
