Summary

Diesel trucks serving Port of Corpus Christi terminals face idling time limits under TCEQ regional rules and city air-quality enforcement, mainly to reduce emissions in neighborhoods near refinery row and the ship channel.

Sec. 382.0191. IDLING OF MOTOR VEHICLE. (a) In this section, 'idling' means allowing an engine to run while the motor vehicle is not engaged in forward or reverse motion. (b) The commission may not prohibit or limit the idling of any motor vehicle with a gross vehicle weight rating greater than 8,500 pounds that is equipped with a 2008 or subsequent model year heavy-duty diesel engine or liquefied or compressed natural gas engine that has been certified by the United States Environmental Protection Agency or another state environmental agency to emit no more than 30 grams of nitrogen oxides emissions per hour when idling.

Full Breakdown

Texas Commission on Environmental Quality regional rules in 30 TAC Chapter 114 cap diesel truck idling at five minutes for vehicles over 14,000 pounds, with exemptions for sleeper berths, traffic, and PTO operations. Corpus Christi enforces the rule at port gates, refinery staging yards, and along Up River Road through truck inspections. Drivers must turn off engines while waiting at terminal queues unless safety or weather conditions justify idling. Enforcement targets ozone precursor reductions in the airshed downwind of the ship channel and Hillcrest neighborhood.

Violations & Fines

TCEQ administrative penalties run up to ten thousand dollars per day per violation; CCPD may issue traffic citations for idling beyond five minutes at port and refinery staging areas.

Frequently Asked Questions

Does this apply to passenger cars?
No, the five-minute idling cap targets heavy-duty diesel vehicles over 14,000 pounds. Passenger cars and light trucks are not subject to the TCEQ regional idling rule.
Can I idle for AC in summer heat?
Generally no for non-sleeper trucks. Sleeper berths qualify for an exemption, but routine cab cooling at port queues does not justify idling beyond five minutes.
