ABSTRACT

A facility that proposes to add or modify a source of air pollution may be required to obtain an approved air permit before starting construction of the new source. Local regulations define the permit requirements for small sources. Federal regulations define the air permit application requirements for major stationary sources. The process for evaluation and approval of a new major source permit application is called New Source Review (NSR). It covers permits for new major sources in both attainment, called Prevention of Significant Deterioration or PSD permits, and Non-Attainment Area (NAA) permits. Although available for over 10 years in “Draft” form, EPA’s

New Source Review Workshop Manual

contains excellent guidance for preparing an air permit application.
