RULE 20.2. NEW SOURCE REVIEW - NON-MAJOR STATIONARY SOURCES

(Adopted & Effective: 5/17/94; Rev. Effective 12/17/97)

(a) APPLICABILITY

This rule applies to any new or modified stationary source, to any new or modified emission unit and to any relocated emission unit being moved from a stationary source provided that after completion of the project, the stationary source is not a major stationary source.

(b) EXEMPTIONS

The exemptions contained in Rule 20.1, Section (b) apply to this rule. In addition, for purposes of this rule, the following exemptions shall apply.
 

  1.  Emission units which are to be temporarily relocated to another stationary source shall be exempt from the provisions of Subsection (d)(1)(ii), provided that:
  1.  Emission units which are intended to be permanently relocated to another stationary source shall be exempt from the provisions of Subsection (d)(1)(ii), provided that:
  1. Emission increases resulting from an air contaminant emission control project shall be exempt from the emission offset requirements of Subsections (d)(5) and (d)(6) of this rule to the extent that the project does not include an increase in the capacity of the emission unit being controlled. Emission increases that are associated with an increase in capacity of the emission unit being controlled shall be subject to the emission offset provisions of this rule, as applicable.

(c) DEFINITIONS

The definitions contained in Rule 20.1, Section (c) apply to this rule.
