EMA urging California to stay with GHG2 schedule

The Truck and Engine Manufacturers Association (EMA) said it is essential that California refrains from adopting greenhouse gas emission standards for new heavy-duty engines and vehicles that are more stringent than those called for under Phase 2. The technology-forcing requirements of the Phase 2 program, like the Phase 1 program, are premised on a fully aligned, 50-state harmonized program.

Issued by Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration Phase 2 standards follow immediately on the heels of the Phase 1 greenhouse gas/fuel efficiency (GHG/FE) standards (that won’t be fully implemented until 2017). The Phase 2 rule is a significantly more ambitious and complex regulatory program with increasingly challenging and more stringent requirements that will be implemented in three stages through the year 2027.

The Truck and Engine Manufacturers Association (EMA) has worked consistently to assure that the EPA and DOT adopt a single, national GHG/FE program applicable in all fifty states. EMA and its members provided significant technical input during the Phase 2 rulemaking process. A vitally important outcome is that EPA and DOT have collaborated to issue a single final rule that includes a harmonized approach to greenhouse gas reductions and fuel efficiency improvements.

“As the primary manufacturers of medium and heavy-duty engines and vehicles in the United States, EMA members are in the process of implementing the Phase 1 GHG/FE standards,” said Jed Mandel, EMA president. “The success of the Phase 1 implementation is directly tied to the fact that the 2011 standards were well matched with EMA member efforts to meet customer demand for more fuel efficient vehicles. We are in the process of reviewing today’s highly complex rule to determine if it aligns with manufacturers’ efforts and customer needs. If not, the Phase 2 program would impose enormous costs on our customers, constrain customer choice, and, as a result, impose significant challenges to its successful implementation.”

Mandel also noted that EPA has made a commitment in the final rule to work with the California Air Resources Board to reduce even further the level of NOx emissions from heavy-duty on-highway engines. “The NOx emissions from heavy-duty on-highway engines have already been reduced to near-zero emission levels--so small as to challenge the ability to measure them,” he said. “Additional incremental reductions could come at a very significant expense and raise the prospect of disadvantageous tradeoffs and impediments to achieving the GHG/fuel efficiency standards that EPA and DOT have adopted today.

“It is important that CARB and EPA engage a broad group as they move forward. There are questions that need to be examined, such as the validation of California’s ozone modeling, the best ways to incentivize the adoption of existing lower emitting technology, and the potential improvement of emission testing protocols. EMA and its members are fully committed to working with EPA, CARB, and other stakeholders to better understand the needs, opportunities and consequences of further lowering the NOx standard.”   ♦
