On the June 29 assembly of the Travis County Commissioners Courtroom, commissioners mentioned methods to scale back particulate matter emissions with Jon White, director of Pure Sources and Environmental High quality, and Adele Noel, the environmental mission supervisor for air high quality.

“We’re right here to handle particulate matter air pollution, and a few particular actions which are being taken by the Central Texas area to scale back PM 2.5, which is ok and inhalable particulate matter, which poses specific well being results,” White advised commissioners.

PM 2.5 is any particulate matter with a diameter of lower than 2.5 micrometers.

“This particulate matter poses a well being threat to everybody as a result of they’re so small that they’ll bypass the nostril and throat, penetrating deep into the lungs, and a few could even enter the circulatory system,” Noel mentioned. She went on to elucidate how publicity to particulate matter has been linked to coronary heart and lung illness, bronchial asthma, coronary heart assaults, start defects, bronchitis and untimely dying.

“Particles could also be emitted immediately from building websites, unpaved roads, smokestacks and fires, in addition to advanced reactions of chemical substances similar to sulfur dioxide, nitrogen oxides … pollution that come from energy crops, industrial machines and vehicles,” Noel mentioned.

The federal Clear Air Act, she defined, requires the Environmental Safety Company to set air high quality requirements for six particular pollution: carbon monoxide, floor stage ozone, lead, nitrogen dioxide, sulfur dioxide and particulate matter. The EPA just lately introduced plans to rethink requirements for PM 2.5. “That most likely implies that it is going to be decrease than the present stage,” Noel speculated.

For Travis County, which means many high-PM areas might be in danger for non-attainment designations.

The EPA defines non-attainment as any space that both doesn’t meet or contributes to a close-by space not assembly ambient air high quality requirements. Not exceeding Clear Air Act requirements can also be vital when it comes to financial and transportation developments getting green-lit.

The development of the brand new Tesla plant and the Samsung plant, for instance, “could not have been attainable if we had exceeded the requirements.” Equally, the Interstate 35 enlargement and Mission Join might have been delayed considerably.

“Our space is extra more likely to exceed the federal commonplace for PM 2.5 than for ozone,” Noel mentioned. She went on to advocate a listing of discount methods – which weren’t touched upon through the dialogue – devised by a subcommittee of the Central Texas Clear Air Coalition together with herself and related events from Austin, Spherical Rock, Bastrop and EPA.

“This record offers many choices for the members to contemplate implementation as a part of their air high quality regional plan,” Noel mentioned.

The Capital Space Council of Governments is distributing the methods to organizations and counties for evaluate. These entities will return to CAPCOG with a listing of the methods they want to implement, which in flip might be added to the CAPCOG Air Regional High quality Plan.

The plan might be introduced to the Clear Air Coalition on Aug. 11. If permitted, it should go on to the EPA.
