In this episode Amy Marshall joins us once again to provide an end of 2021 air quality regulatory update. It has been 14 months since we first launched our new podcast format with a lookahead to a potential Biden administration. Now we are just under a year into the administration and explore the latest policy, regulatory, and legal activity. Topics covered include New Source Review, ambient standards, air toxics, and environmental justice among others. As always, we discuss some practical advice on how this activity will translate into permitting and environmental compliance programs.
