Acid Deposition, Stratospheric Ozone Protection, Climate Change
Over the previous couple of classes we mentioned various air quality issues other than criteria air pollutants and hazardous air pollutants – that is, those pollutants that most often are associated with rather direct effects on our health and the health of our ecosystems. Today we are going to explore policies, laws and regulations as they relate to larger scale pollution issues – specifically:
- Acid Deposition (formerly acid rain)
- Stratospheric Ozone Protection (good ozone)
- Climate Change (global warming)
We are not going to review the scientific bases for any of these phenomena. If you’re rusty on current scientific thought (including debate) on these issues, stop here and do some reading. For a quick refresher, go back to the Plain English Guide to the Clean Air Act – at least for acid deposition and ozone depletion. For the latest on global climate change, take a look at the synopsis on EPA’s home page, or go to any several articles in such publications as Environmental Manager (EM) by the Air & Waste Management Association or Environmental Science & Technology by the American Chemical Society.
To get us started let’s recall that the Clean Air Act Amendments of 1990 contains two new titles on these topics.
- Title IV Acid Deposition Control
- Title VI Stratospheric Ozone Protection
See Power Point presentations on Acid Deposition and Stratospheric Ozone.
