Over the years, through various legal decisions, this definition narrowed to include those water bodies and features that were connected to a flowing water body, like a stream or lake. Swampy areas that were not directly connected were considered "isolated wetlands" and were excluded... Continue Reading >>

New Ozone Regulations - What's the Right Balance?

Then there's ground level ozone, which can be harmful to our lungs. It is formed through a chemical reaction when nitrogen oxides (NOx) and volatile organic compounds (VOCs) interact with sunlight. Emissions from power plants, industrial facilities, automobiles, gasoline vapors and solvents are all sources of NOx and VOCs. Natural sources, such as plant life and fires, also contribute to the formation of ozone.

The current national standard for ozone is 75 parts per billion (ppb), which is 33 percent lower than it was in 1980. Most of the country is meeting this standard, but there are still dense population centers like Houston and Southern California that do not meet the current standard.

Based on 40-year-old provisions in the Clean Air Act, EPA evaluates the standard every... Continue Reading >>
