That, in essence, is the response of EPA officials to criticism that they are whiffing on an opportunity to strengthen commercial jet aircraft engine pollution regulations and benefit environmental justice communities.
The tension is on display in a newly published final rule aimed at syncing U.S. emissions standards for new engines with the guidelines of the International Civil Aviation Organization (ICAO), a U.N. agency responsible for air transport issues.
With a January 2023 deadline looming, however, EPA acknowledges the revised standards will have no immediate effect in curbing releases of harmful particulate matter and highlights their importance in keeping domestic engine manufacturers competitive in the global marketplace.
“EPA has historically given significant weight to uniformity with international requirements as a factor in setting aircraft engine standards,” the rule says. “The fact that most airplanes already meet the standards does not in itself mean that the standards are inappropriate, provided the agency has a reasonable basis after considering all the relevant factors.”
But it adds that EPA views “regulation of aircraft PM emissions as a long-term process, with the potential for successive standards of increasing stringency.”
In a follow-up to studies showing that many communities near airports have disproportionately high populations of people of color and low-income residents, the agency is also undertaking an analysis to more fully understand the resulting “human health or environmental effects.”
An EPA spokesperson, noting that many agency employees are out Wednesday in advance of the Thanksgiving holiday, could not immediately address questions on the analysis’s expected completion date or plans by EPA to explore stricter engine standards.
Particulates are linked to an array of cardiovascular and respiratory ills, including a higher risk of early death for people with preexisting conditions.
The final rule published Wednesday appears little changed from an earlier draft that came under fire at a February public hearing.
While President Joe Biden vowed to “usher in a clean energy revolution” and prioritize environmental justice concerns, “not only does EPA’s proposed PM rule fail to meet those goals, it doesn’t even take them seriously,” said Scott Hochberg, an attorney with the Center for Biological Diversity, according to a transcript.
“For the safety of our communities and the environment, PM reductions from aircraft are needed,” Bonnie Soriano, a branch chief with the California Air Resources Board, said later in the hearing. Aircraft are a major source of those emissions, Soriano said, adding that “EPA should stop outsourcing” its policies to ICAO.
