HB 3679 would establish temporary regulatory flexibility to facilitate the transportation of agricultural commodities during declared disasters. The bill authorizes the Texas Department of Transportation (TxDOT), with approval from the Department of Public Safety (DPS), to issue special permits allowing certain divisible overweight or oversize vehicles to transport agricultural commodities to or from disaster-affected areas during a presidential major disaster declaration or a state disaster declaration. The permits would expire when the disaster declaration ends, or earlier if a federal waiver allowing the use of dyed diesel fuel on public highways expires. The bill also authorizes TxDOT to adopt implementing rules and impose permit conditions related to routing, weight limits, operating hours, lighting, and escort vehicle requirements to protect roadway safety and infrastructure.
The bill also amends the Tax Code to permit qualified end users to operate motor vehicles on public highways using dyed diesel fuel during periods in which the Internal Revenue Service has suspended federal penalties for that fuel's highway use in designated disaster areas. Additionally, it updates cross-references in the Transportation Code so that vehicles operating under the new agricultural disaster permit are treated consistently with other permitted overweight or oversize vehicles when traveling on roads subject to state or county weight restrictions. The legislation expressly preserves federal size and weight limitations on the Interstate Highway System and Federal-Aid Primary Highway System unless federal law is subsequently amended to authorize heavier loads.
The Committee Substitute for HB 3679 significantly narrows the scope of the originally filed bill by limiting the disaster-related flexibilities to agricultural commodity transportation occurring during an active disaster, rather than before, during, and after a disaster. The introduced bill authorized special overweight and oversize permits before a forecasted disaster with approval from the Texas Division of Emergency Management (TDEM), during an active disaster, and for up to 120 days afterward. The Committee Substitute eliminates the pre-disaster permitting authority entirely, removes TDEM's role in authorizing permits before anticipated events, and instead limits permit issuance to periods covered by a presidential major disaster declaration or a state disaster declaration, with authorization from the Department of Public Safety (DPS). It also restricts permits to deliveries to or from sites directly affected by the declared disaster, rather than allowing unrestricted delivery of agricultural commodities.
The Committee Substitute also substantially revises the dyed fuel provisions. As originally filed, the bill allowed qualified users to operate vehicles on public highways using dyed motor fuel beginning with a state disaster declaration and continuing until 30 days after the declaration ended. It applied broadly to declared disaster areas and, in some circumstances, to vehicles operating outside the disaster area if they had been fueled within it. The substitute instead limits the exemption to dyed diesel fuel used only during periods in which the Internal Revenue Service has suspended federal penalties for highway use of dyed diesel, tying state law directly to existing federal emergency waivers. The substitute also removes the automatic 30-day post-disaster extension contained in the introduced version.
Finally, the Committee Substitute shortens the duration of the new agricultural transport permits and simplifies the administrative framework. The introduced bill allowed permits to remain valid for up to 120 days after either a disaster declaration or pre-disaster authorization by TDEM. Under the Committee Substitute, permits expire when the applicable disaster declaration ends, or earlier if the federal dyed diesel waiver expires for vehicles operating under that provision. The substitute also removes the statutory definition of "Division," eliminates the application process through TDEM, and transfers operational oversight to DPS in coordination with TxDOT. The remaining provisions governing permit conditions, roadway protections, updates to weight-limit cross-references, and compliance with federal interstate weight restrictions remain substantially unchanged.
