CATEGORICAL EXCLUSION DETERMINATION FOR

CATEGORICAL EXCLUSION DETERMINATION FOR THE PROPOSED PROJECT OF: Dickinson (Stark County), North Dakota DRINKING WATER STATE REVOLVING FUND PROJECT NUMBER: 4500242-01 The North Dakota Department of Environmental Quality (NDDEQ) has conducted a review of the proposed 2022 Watermain Replacement for the City of Dickinson in accordance with the National Environmental Policy Act (40 CFR Part 6). The NDDEQ has determined that this project is eligible for a categorical exclusion and is exempt from further substantive environmental review. Because the proposed project meets the criteria for a categorical exclusion, a full Finding of No Significant Impact and Environmental Assessment will not be required. Following is a description of the proposed project and a brief statement of how the project meets the criteria for a categorical exclusion. The proposed project consists of watermain and lead service line replacements throughout the City of Dickinson. The watermain is constructed of cast iron pipe and is prone to watermain breaks that have the potential to introduce contamination into the distribution system, disruption of service, and possible long-term lack of service. Service lines constructed of lead have the potential to leach lead into the drinking water. The proposed project will replace the existing cast iron watermains with polyvinyl chloride (PVC) pipe and replace existing lead service lines with high density polyethylene (HDPE) pipe. The improvements will prevent potential contamination from entering the distribution system and will minimize disruptions of service. The City of Dickinson plans to apply for a Drinking Water State Revolving Fund loan of $2,800,000 to finance the project. This project is being granted an exclusion because the improvements within previous-disturbed areas. No previously undisturbed areas will be affected by the construction activities. The North Dakota State Historic Preservation Officer has concluded that no historic properties will be affected by this project (ND SHPO Ref.: 22-5435) provided it takes place in the location and in the manner described in the documentation and provided all borrow comes from an approved source. It has been determined that exempting the proposed project from further review under the National Environmental Policy Act will not result in adverse impacts to the population or area of Dickinson and Stark County. The documentation to support this decision will be on file and available for public review at the NDDEQ, Division of Municipal Facilities. Comments concerning this decision may be addressed to Shannon Fisher, DWSRF Program Manager, Division of Municipal Facilities, North Dakota Department of Environmental Quality, 4201 Normandy Street, Bismarck, ND, 58503-1324.
