Power plants and other industrial sites in parts of the U.S., including construction material producers, may soon face more stringent nitrogen oxide emissions requirements as part of a “good neighbor” plan proposed by the U.S. Environmental Protection Agency on March 11.
The proposed rule would use a variety of regulatory strategies to reduce emissions of nitrogen oxide (NOx), a key component in the formation of ground-level ozone, which is known to have negative health and environmental impacts in areas downwind of the emission sources, often beyond state boundaries.
