Title 40: Protection of Environment
PART 51—REQUIREMENTS FOR PREPARATION, ADOPTION, AND SUBMITTAL OF IMPLEMENTATION PLANS
Subpart A—Air Emissions Reporting Requirements

Appendix A to Subpart A of Part 51—Tables

Table 1 to Appendix A of Subpart A—Emission Thresholds by Pollutant (tpy¹) for Treatment of Point Sources as Type A Under 40 CFR 51.30.

Pollutant	Emissions threshold for Type A treatment
(1) SO₂	≥2500.
(2) VOC	≥250.
(3) NO_X	≥2500.
(4) CO	≥2500.
(5) Pb	Does not determine Type A status.
(6) PM₁₀	≥250.
(7) PM_2.5	≥250.
(8) NH₃²	≥250.

¹tpy = Tons per year of actual emissions.

²Ammonia threshold applies only in areas where ammonia emissions are a factor in determining whether a source is a major source, i.e. , where ammonia is considered a significant precursor of PM_2.5.
