Green Mountain Power Water Quality Certification Notice
Summary
FERC notified Vermont Department of Environmental Conservation of the receipt date (April 1, 2026) and deadline (April 1, 2027) for acting on Green Mountain Power Corporation's Clean Water Act section 401(a)(1) water quality certification request. Under 18 CFR 5.23(b)(2), failure to act by the deadline results in deemed waiver of the certifying authority.
What changed
FERC issued a procedural notice to Vermont DEC establishing the one-year timeline for acting on Green Mountain Power Corporation's water quality certification request under Clean Water Act section 401(a)(1). The notice confirms the April 1, 2026 receipt date and sets April 1, 2027 as the deadline, after which certifying authority is automatically waived under federal law.
For Green Mountain Power and similar hydro project operators, this notice underscores the importance of tracking state agency action timelines. If Vermont DEC fails to issue a decision by April 1, 2027, the certification authority is deemed waived under 33 U.S.C. 1341(a)(1), potentially affecting project licensing or relicensing proceedings before FERC.
