Non-Attainment New Source Review

Non-attainment New Source Review may be required in the permitting of new or modified source of air emissions located in the non-attainment areas. To be subject to these regulations, a facility must already be or will become a major emitting source (greater than 100 tons per year) of volatile organic compounds (VOC) or oxides of nitrogen (NOx), which are precursors for ozone. VOC and NOx are regulated under Prevention of Significant Deterioration (PSD) and Non-Attainment New Source Review (NSR) Regulations. Non-Attainment New Source Review requires that a company demonstrate that the proposed project meets the Lowest Achievable Emission Rate (LAER), provides offsets for each precursor at a ratio of 1 to 1.1, and conducts an alternative site analysis. In addition to those requirements, all sources in the state owned by that entity must be in compliance. The Air Quality Division has provided some resources below for facilities preparing an application for Non-Attainment New Source Review.

If you are preparing a PTI application that includes Non-Attainment New Source Review, it is recommended that you schedule a pre-application meeting. Please contact Annette Switzer at 517‑284‑6803 to schedule a pre-application meeting or to ask any questions regarding Non-Attainment New Source Review applications.
