# §63.8182. Am I subject to this subpart?

- (a) **You are subject to this subpart if you own or operate a mercury cell chlor-alkali plant.**
- (b) You are required to obtain a title V permit, whether your affected source is a part of a major source of hazardous air pollutant (HAP) emissions or a part of an area source of HAP emissions. A major source of HAP is a source that emits or has the potential to emit any single HAP at a rate of 10 tons or more per year or any combination of HAP at a rate of 25 tons or more per year. An area source of HAP is a source that has the potential to emit HAP but is not a major source. Nothing in this subpart revises how affected sources are aggregated for purposes of determining whether an affected source is a part of an area, nonmajor, or major source under any provisions of the Clean Air Act (CAA) or EPA's regulations. For information on aggregating affected sources to determine what is a source under title V, see the definition of major source in 40 CFR [70.2](/cfr/40/70.2.md), [71.2](/cfr/40/71.2.md) and [63.2](/cfr/40/63.2.md).
- (c) Beginning on December 19, 2006, the provisions of [subpart E](/cfr/40/subpartE.md) of [40 CFR part 61](/cfr/40/part61.md) that apply to mercury cell chlor-alkali plants, which are listed in [paragraphs (c)(1) through (3)](#c-1..c-3) of this section, are no longer applicable.
  - (1) [§ 61.52(a)](/cfr/40/61.52.md?p=a);
  - (2) § [61.53(b)](/cfr/40/61.53.md?p=b) and [(c)](/cfr/40/61.53.md?p=c); and
  - (3) § [61.55(b)](/cfr/40/61.55.md?p=b), [(c)](/cfr/40/61.55.md?p=c) and [(d)](/cfr/40/61.55.md?p=d).
