Section 74:36:10:06 - Causing or contributing to a violation of any national ambient air quality standard

This section applies to any major stationary source or major modification to an existing major source that is located in an attainment or unclassifiable area that may cause or contribute to violation of a national ambient air quality standard. A major stationary source or major modification to an existing major source is considered to cause or contribute to a violation of a national ambient air quality standard if the source or modification would, at a minimum, exceed the following significance levels at any locality that does not or would not meet the applicable national standard:

POLLUTANT AND SIGNIFICANT LEVELS

The owner or operator of a new major stationary source or major modification to an existing major source may reduce the impact of its emissions on air quality by obtaining emission offsets to compensate for its adverse ambient impact where the new major source or major modification to an existing major source would otherwise cause or contribute to a violation of the national ambient air quality standard. The procedures for determining credit for emission offsets are those in § 74:36:10:07.
