129 Neb. Admin. Code, ch. 1, § 087 - "Minor source baseline date"
"Minor source baseline date" means the earliest date after the trigger date on which a major stationary source or a major modification subject to the Prevention of Significant Deterioration Program, as defined in Chapter 1, submits a complete permit application. The trigger date is, in the case of PM10 and sulfur dioxide, August 7, 1977, in the case of nitrogen dioxide, February 8, 1988, and in the case of PM2.5, October 20, 2011. Any minor source baseline date established originally for the TSP increments shall remain in effect and shall apply for purposes of determining the amount of available PM10 increments, except that the Department may rescind any such minor source baseline date where it can be shown, to the satisfaction of the Department, that the emissions increase from the major stationary source, or the net emissions increase from the major modification, responsible for triggering that date did not result in a significant amount of PM10 emissions.
The baseline date is established for each pollutant for which increments or other equivalent measures have been established if the area in which the proposed source or modification would construct is designated as attainment or unclassifiable under section 107(d)(1)(A)(ii) or (iii) of the Act for the pollutant on the date of its complete application under 40 CFR 52.21 or to regulations approved pursuant to 40 CFR 51.166 or to Chapter 19; and, in the case of a major stationary source, the pollutant would be emitted in significant amounts, or in the case of a major modification, there would be a significant net emissions increase of the pollutant.
