Nikishka Bay Utilities, Inc
Nikiski, Alaska
The Alaska Department of Environmental Conservation’s (Department) State Revolving Fund Program has conducted a review of the above referenced project in accordance with the Operating Agreement between the Department and the U.S. Environmental Protection Agency (EPA) for implementing the Drinking Water State Revolving Fund (DWSRF) loan program. The Department has determined that this project is eligible for a Categorical Exclusion (CE) in accordance with 18 AAC 76.235. Accordingly, the Department is exempting the project from further environmental review requirements under the Department’s EPA-approved State Environmental Review Process.
Due to PFAS contamination in the current water source in excess of 100 times the proposed EPA Maximum Contaminant Level, this project will investigate the possibility of identifying a new groundwater source in the area. The anticipated scope of work may include a geomorphic study of a new well site location, exploratory drilling as necessary, groundwater testing, and preliminary design of a new source facility and transmission main. The scope of work may also include a pilot study to investigate treatment options using an alternative filtration media. A DWSRF loan in the amount of $560,005 has been requested for this project.
The project is eligible for a CE because undertaking this action:
- Will not significantly affect the degree of treatment or capacity of the existing facility;
- Will not directly or indirectly affect cultural resources, habitats of endangered or threatened species, or environmentally important natural resources area;
- Will not have a significant effect on the quality of the human environment;
- Will not cause significant public controversy.
The determination shall become effective upon distribution by the Department and can be revoked at any time that adverse information is made available. The documentation to support this decision will be on file with the Alaska Department of Environmental Conservation’s State Revolving Fund Program. To request a copy of the CE, contact:
