Truck buyers will get an important view of truck technology for when two federal agencies release the proposal of the administration for the Phase 2 of maximum emission of greenhouse gases generated by heavy and medium duty trucks. The Environmental Protection Agency and the National Highway Traffic Safety Administration (NHTSA) are expected to produce a proposal for a second phase of truck regulation by March 31 a deadline set by the president. The proposed rule on maximum for carbon dioxide emissions and gallons of fuel used per 1,000 ton-miles traveled would then be made final in March 2016, according to the schedule. Another critical regulator on the issue is the California Air Resources Board.
NHTSA has been ordered to conduct an environmental impact study on the implementation of the new planned regulation. Environmental interest groups urged the regulators to act boldly asking serious action against climate change. Trucking groups implored the National Highway Traffic Safety Administration not to cripple the industry by ordering the use of new technologies that would radically increase the cost of trucking equipment. American Transport Association (ATA) has called for delay of 18 months for the investment of additional environmental technologies, meaning that saving the miles per gallon savings would pay for the added cost.
The photo-chemical smog similar to nitrogen oxides (NOx) is particularly problematic in the San Joaquin Valley and the state’s south coast, Rogalski said. The board’s current preference, Rogalski said, would be to keep Phase 2 development, aimed at greenhouse gases, and then switch focus back to NOx after Phase 2 is adopted.
Also she mentioned that CARB has been working with the Southwest Research Institute on NOx reduction. Scientists and engineers are trying to develop engines that emit just 0.02 grams per brake horse-power-hour, down from the current ceiling of 0.20 gram. Kim Heroy Rogalski, CARB program manager said the board would prefer to see a “harmonized approach”.
