Comparison: State vs. Federal
• Rules. Minnesota requires a source to obtain an air permit from the Minnesota Pollution Control Agency (MPCA) before construction, process modification, reconstruction, or operation of an air emissions unit, emissions facility, or stationary source. Minnesota’s air regulations provide for state permits and federal operating permits, depending on a source’s potential to emit (PTE). Major sources are required to comply with the applicable provisions of nonattainment new source review (NSR) and/or Prevention of Significant Deterioration (PSD) for construction and modification permits and Part 70 for operating permits. See the state sections NEW SOURCE REVIEW and TITLE V, respectively, for more information. In addition, the state has programs for general permits, registration permits, and capped permits that allow for more flexibility in operation.
• Administration and enforcement. The MPCA is responsible for the administration and enforcement of Minnesota’s air emissions permitting program.
