NOTICE OF FINDING OF NO SIGNFICANT IMPACT AND
NOTICE OF INTENT TO REQUEST RELEASE OF FUNDS

(843) 549-5221
These notices shall satisfy two separate but related procedural requirements for activities to be undertaken by Colleton County.
REQUEST FOR RELEASE OF FUNDS
On or about December 16, 2019, Colleton County will submit a request to the SC Department of Commerce/Grants Administration Division for the release of CDBG funds under Title I of the Housing and Community Development Act of 1974, as amended, to undertake a project known as the Colleton County Project with a total of $550,000 including $500,000 CDBG funds where the County proposes to use funding to upgrade the water lines in the identified neighborhood. The primary activity with this project is to replace the old, small water lines with larger water lines and add fire hydrants. Approximately 7,001 LF of new 6” water line will replace the existing small water line to connect the water line to provide a looping effect and improve water pressure and flow to allow for installing fire hydrants to cover the area with better fire protection. Additionally, the project will include the installation of 5 new fire hydrants, 12 new gate valves, replacement of all service assemblies, and looped interconnections to an existing 12-inch water main, an existing 8-inch water main, and an existing 6-inch water main. The looping improves flow capabilities, reduces pressure losses, and helps to maintain fresh water.
Proposed 6-inch water main along Live Oak Street will cross wetlands depicted on the USFWS National Wetlands Inventory Maps beginning approximately 1,135 south of Live Oak Street’s intersection with Barracada Road. The crossing is proposed to be made by the directional drill method using fused HDPE pipe extending approximately 300 feet southward in a manner such that there will be no impacts to these wetlands. Both the entry point and the exit point will be positioned outside the boundaries of the wetlands. Directional drilling of utility pipelines has now advanced to the point that such wetlands crossings need not be designed with one continuous arc but rather can be turned as needed to extend under streams and associated wetlands such as Shereau Branch without having to go excessively deep. This will allow the design to proceed such that there will be a minimum of 4 feet of earth cover, but not so deep that access is restricted if a leak or rupture were to occur. A wetlands crossing in this manner would be allowed by the US Army Corps of Engineers Nationwide Permit #12-Utility Line Activities and would not require the submittal of a Pre-Construction Notification.
Since there are no wetlands within the right-of-way of Barracada Road and the water mainalong that road is proposed to be completely within that right-of-way, there will be no water mains crossing wetlands along that road.
The design of the proposed project will incorporate the use of Best Management Practices (BMP’s) particularly as it relates to sediment/erosion control and the protection of the wetlands to be crossed.
FINDING OF NO SIGNIFICANT IMPACT
Colleton County has determined that the project will have no significant impact on the human environment. Therefore, an Environmental Impact Statement under the National Environmental Policy Act of 1969 (NEPA) is not required. Additional project information is contained in the Environmental Review Record (ERR) on file at Colleton County Administration Office, 109 Benson Street, Walterboro, SC and may be examined or copied weekdays 9A.M to 5P.M.
