Berne was settled in 1852 by Mennonite immigrants who came directly from Switzerland, and named the community for the capital of Switzerland. They began the chore of preparing for farming by clearing the land.
Intentions, however, were not always equal to actions. Implementation of the Clean Air Amendments was made difficult by a reluctant automobile industry and the energy crisis of the early 1970s. The 1970 act gave the auto industry a temporary way out of meeting the tougher standards.
Major amendments were added to the Clean Air Act in 1977 (1977 CAAA). The 1977 Amendments primarily concerned provisions for the Prevention of Significant Deterioration (PSD) of air quality in areas attaining the NAAQS. The 1977 CAAA also contained requirements pertaining to sources in non-attainment areas for NAAQS.
