Bill
H 3357
Massachusetts H.3357 mandates state purchases/leases of new medium-heavy-duty trucks be zero-emission by 7/1/2025, full fleet by 6/30/2035, delaying CARB-like rules.
Note: the materials you provided include two different measures under the same file/bill label. One is a Massachusetts bill (House No. 3357 / “An Act relative to responsibly reducing emissions in the transportation sector”) that would require state purchases of medium‑ and heavy‑duty trucks to be zero‑emission vehicles and delay certain emissions regulations. The other is a South Carolina joint resolution to create a “Shipping Transportation and Port Bridge Safety Study Committee.” Below are concise, clearly organized summaries of both measures and their procedural status so you can confirm which one you want a deeper focus on.
Summary A — Massachusetts: H.3357 (“An Act relative to responsibly reducing emissions in the transportation sector”)
- Purpose and intent
- Require the Commonwealth to shift state‑owned/leased medium‑ and heavy‑duty truck purchases to battery electric vehicles (BEVs) and set an in‑fleet deadline for full transition, while delaying implementation of certain state regulation mirroring California’s heavy‑duty rules.
- Key provisions
- Starting July 1, 2025, all Commonwealth purchases/leases of new medium‑ and heavy‑duty trucks must be zero‑emission models (defined as battery electric trucks).
- The Commonwealth must ensure its medium‑ and heavy‑duty fleet (owned or leased) is comprised of zero‑emission vehicles by June 30, 2035.
- Exception: the secretary may buy a non‑BEV if no battery electric model meets operational needs or existing charging infrastructure cannot support the vehicle.
- Annual reporting requirement (due July 1 each year) to legislative clerks and chairs of the joint committee on transportation. Reports must list all medium‑ and heavy‑duty trucks by agency and describe propulsion type (ICE, mild hybrid, plug‑in hybrid, BEV, hydrogen fuel cell, CNG/LNG, propane, etc.). If a BEV is not purchased/leased, the secretary must explain why.
- Department of Environmental Protection may not implement or enforce the “Advanced Clean Trucks” and “Heavy‑Duty Omnibus” regulations (California CARB‑based provisions for increasing ZEV sales and NOx standards) earlier than July 1, 2027.
- Effective immediately upon passage.
- Who is affected
- Commonwealth agencies that procure/lease medium‑ and heavy‑duty trucks; truck manufacturers and dealers supplying government fleets; state infrastructure planners for charging; DEP implementation schedule for heavy‑duty regulations.
- Procedural/timeline notes (as provided)
- Prefiled 12/05/2024; introduced/read first time 01/14/2025; referred to Committee on Labor, Commerce and Industry (and to State Administration and Regulatory Oversight in other entries); Senate concurred 02/27/2025; hearing scheduled 07/22/2025 (10:00 AM–1:00 PM, location A‑1).
Summary B — South Carolina: Joint Resolution — “Shipping Transportation and Port Bridge Safety Study Committee”
- Purpose and intent
- Establish a temporary study committee to evaluate whether state and federal safety standards and protective measures are adequate to prevent collisions between large vessels and bridge supports—including pilotage standards, bridge pier resilience, and vessel protection systems—after high‑profile bridge incidents.
- Key provisions
- Creates a 9‑member “Shipping Transportation and Port Bridge Safety Study Committee” to:
1. Examine current state and federal safety standards for navigation of large vessels under major waterway bridges (including pilotage training and comparison to industry best practices).
2. Assess bridge support pier/structure vulnerability to vessel impact and the likelihood of collapse or impassability from such damage.
3. Evaluate existing ship collision barriers and other vessel protection devices near bridge supports.
- Committee must issue a report with findings and legislative/regulatory/policy recommendations (including potential enhancements to pilotage training) to the General Assembly before January 1, 2027.
- Membership: 2 state senators (one from a district with a major port), 2 state representatives (one from a port district), 2 civil engineers experienced in over‑water bridge design/construction, President/CEO of the State Ports Authority (or designee), Secretary of Transportation (or designee), Director of Department of Public Safety (or designee).
- Members serve without compensation but may receive mileage/per diem; meetings supported by legislative committees; may obtain non‑personally‑identifiable data from state agencies.
- Committee terminates upon delivery of the report (by 1/1/2027); resolution effective upon governor’s approval.
- Who is affected
- State transportation and public safety agencies, ports authority, bridge engineers, maritime pilots and pilotage authorities, coastal communities with bridges and ports.
- Context and motivation
- Cites the collapse of the Francis Scott Key Bridge (Baltimore, March 26, 2024) and subsequent concerns about large ship/bridge interactions and adequacy of protections.
Which summary do you want expanded?
- I can expand the Massachusetts H.3357 summary into a full bill‑impact analysis (cost, procurement impacts, infrastructure requirements, stakeholder effects) or produce a detailed outline of the South Carolina study committee’s likely findings and policy options. Tell me which one to prioritize.
