MnDOT warns conference committee that delayed greenhouse‑gas rules, rail cuts and asset targets would reshape construction program

Nancy Daubenberger, commissioner of the Minnesota Department of Transportation, testified to the transportation conference committee about agency priorities and concerns in reconciling House and Senate transportation bills.

"The bill provides important investments to help construct, operate, and maintain Minnesota's transportation system in challenging times," Daubenberger told conferees, while also flagging several areas where the agency sees risks and tradeoffs.

Why it matters: MnDOT is the state agency charged with delivering highway, bridge and multimodal projects. Its assessment of program impacts informs what projects can be built, when, and what funding or programmatic changes would be required.

MnDOT's principal concerns raised to the committee

- Greenhouse‑gas and VMT provisions: Daubenberger said the House proposal to delay greenhouse‑gas and vehicle‑miles‑traveled (VMT) requirements for three years is "concerning." She explained that transportation is the state's leading source of greenhouse‑gas emissions and that delaying statutory mitigation or offset requirements would shift accountability away from state and local governments that deliver transportation infrastructure.

- Passenger rail funding: MnDOT told the committee it is working with the Federal Railroad Administration and BNSF on the Northern Lights Express and other corridor work. The Commissioner said an $8.94 million House cut and larger Senate cancellations limit the department’s ability to support Borealis/Northern Lights service and multi‑state partnerships.

- Asset sustainability ratio and pavement funding: MnDOT said the Senate’s adjusted effective date for the asset sustainability ratio is an improvement but described the House target as triggering immediate, large shifts to pavement work. Daubenberger provided estimated resource impacts: meeting the House targets immediately would require shifting about $175 million to $240 million per year to pavement (8‑year total $1.4–$1.9 billion). The Senate timing change would still require an increase roughly in the $65–$80 million per year range over time and could reduce funding for freight, safety and other non‑pavement projects in the 2031–2034 period.

- Redirecting efficiency savings: MnDOT prefers the House approach to any redirecting of calculated efficiency savings; the Senate version that dedicates those savings to a "quarters of commerce" program would effectively reduce the existing state road construction program by about $90 million per year and shift roughly $15 million per year out of operations and maintenance budgets.

Daubenberger also asked the committee to consider workload and staffing needs tied to proposed new reporting and portal requirements, noting the project portal proposal would require additional staff to maintain live, updated program information.

What MnDOT will provide next

Daubenberger said MnDOT will continue to work with conferees on technical fixes and recommended striking statutory language that requires distribution calculations based on prior consecutive project selection rounds (Minn. Stat. § 161.088, subd. 4a). The department asked conferees to weigh tradeoffs carefully because meeting some policy targets would force the department to remove or delay other projects already scoped and in public engagement.

Ending: Daubenberger closed by offering technical input and asking conferees to consider the agency's operational constraints when finalizing statutory targets and funding allocations.
