Committee votes to concur on H.481 — repeal of sunset on clean‑water property‑transfer surcharge and stormwater compliance measures

On 2025-04-01 the Senate Committee on Finance concurred with version 4.1 of H.481, a bill that (1) extends deadlines for compliance with the 3‑acre stormwater general permit in specified watersheds, (2) modifies financing programs and gives municipalities additional authorities to address parcel‑based stormwater compliance issues, and (3) repeals the scheduled sunsets on the clean‑water surcharge that is applied to the property transfer tax, leaving the surcharge at its current rate unless the legislature acts otherwise.

Michael Grady, the bill presenter, told the committee the 3‑acre general permit campaign followed a federal TMDL process and that some older subdivisions and parcels lack an accountable entity or feasible on‑site options, so affected property owners can face “very expensive” compliance costs or assessments. He described three parcel‑based problems: subdivisions without homeowners associations or a responsible permit holder, parcels lacking land to install management practices, and contiguous drainage where one subdivision’s runoff requires another to design for both systems.

To address those issues, the bill extends the Lake Champlain and Lake Memphremagog watershed deadline for 3‑acre permit compliance to Aug. 1, 2028, and delays other permit deadlines either to Oct. 1, 2038, or to five years after a site‑specific waste‑load allocation is established, whichever comes sooner. The bill authorizes municipalities that assume full legal responsibility for a stormwater system to assess a municipal special assessment on system users (with procedural protections and consent thresholds in the text) and changes two state assistance programs — the developed‑lands implementation program and the municipal stormwater implementation program — so they can provide broader and more flexible financial assistance (not limited to grants) and apply to a wider set of permit holders.

The bill also directs the Clean Water Board to recommend at least $1,000,000 annually for the municipal stormwater implementation program to assist with 3‑acre permit compliance, and it calls for a recommended one‑time $5,000,000 appropriation from the Clean Water Fund in FY2027 to support the municipal stormwater implementation program. The bill creates a study committee to evaluate regional stormwater utilities and to recommend cost‑effective, equitable approaches and statutory fixes; that group is to report by Jan. 15, 2027.

James (Fiscal Office) summarized the fiscal‑note considerations and told the committee that repealing the scheduled reductions in the property‑transfer surcharge would maintain existing revenue flows to the Clean Water Fund; he described the Clean Water Fund and the two financing programs as the major fiscal levers implicated. He also reported a small administrative cost for the study committee and said the fiscal office had posted an updated fiscal note to the bill page.

Senator Hardy moved concurrence with version 4.1 of H.481. The chair called the roll; the committee recorded the motion as approved on the floor (roll call recorded in committee minutes). The bill’s changes take effect July 1, 2025, with some Clean Water Fund priority provisions effective Oct. 1, 2025.
