... 6 A General Approach to Assessing Impacts of NSR Rule Changes INTRODUCTION In this section, a general approach to considering the impacts of New Source Review (NSR) rule changes on emissions, energy efficiency, innovation regarding pollution prevention and pollution control, and public health is outlined.

... 172 CHANGES IN NEW SOURCE REVIEW PROGRAMS because the effect of other regulations varies across types of sources, these assessments should be done separately for different industries. Table 6-1 outlines the general scenarios that will be considered for each major industry and pollutant.2 The precise scenarios concerning other regulations or NSR interpretation might depend on the pollutant and the industry.

... 174 CHANGES IN NEW SOURCE REVIEW PROGRAMS pose a set of analyses using sector-wide models such as IPM, encompassing a wider range of possible regulatory and technological developments than considered previously.3 For data-limited industries, the committee proposes a qualitative assessment -- not likely, possible, and likely accompanied by small, medium, and large emission increases and decreases. Empirical data, to the extent that they are available and pertinent, will be used.
