Maine Hydro Project Awaits Water Quality Decision

## Summary

Hackett Mills Hydro Associates asked Maine’s environmental agency for permission to keep their water clean while running their hydro project. Maine has one year, until May 22, 2027, to approve or deny this request. If they don’t decide by then, the approval is automatically given, so the project can move forward without delay.

## Effects PRIA read

- One-year deadline for Maine DEP: benefit, low. Hackett Mills Hydro submitted a Clean Water Act section 401(a)(1) water quality certification request on May 22, 2026. Maine’s Department of Environmental Protection has one year — until May 22, 2027 — to approve or deny that request.
- Automatic waiver if no state action: benefit, medium. If Maine DEP does not act on the water quality certification request by May 22, 2027, the certifying authority is deemed waived under Clean Water Act section 401(a)(1). That waiver allows the project to proceed without the state certification after that date.
