Prevention of Significant Deterioration (PSD)
The purpose of the state PSD program is to implement the Federal Clean Air Act
requirements for the prevention of significant deterioration of air quality.
These insure that the permitting of proposed new industrial facilities and the
associated economic growth will occur in a manner consistent with the
preservation of clean air resources.
The program provides for special emphasis on implementation of
best available control technology, protection of scenic areas
such as national parks, and informed public participation.
