ALEXANDRIA, VA.—NACS on Friday submitted public comments to the Environmental Protection Agency (EPA) on its review of the National Ambient Air Quality Standards (NAAQS) for particulate matter in advance of the June 29 deadline.
The agency is reviewing NAAQS and released its draft proposal to maintain the current primary standard meant to protect against fine particle exposures, the primary standard meant to protect against course particle exposure and secondary standards. NACS supports EPA’s draft proposal to keep the current standards.
In its letter, NACS shared concerns with EPA that there is a lack of available scientific evidence and analyses to support further reductions in NAAQS for particulate matter, and there was a question as to whether or not these reductions would lead to significant improvements in air quality. In addition, such reductions and modifications to NAAQS could lead to states and cities suddenly being in nonattainment zones, which would lead to changes in policy regarding the composition of motor fuels.
This proliferation of fuel blends becomes problematic to the fuel supply chain, especially in times of natural disasters, which can lead to increased fuel prices for drivers, NACS wrote.
