Example: New Major Source
(Type 1)
Will the following “unnamed” source, proposed to be built in a severe
ozone nonattainment area (HGB), be major for NNSR and/or PSD? If
so, for which pollutants?

NNSR: Yes, major source because NOX≥25 tpy
PSD: Yes, major source for all pollutants because CO≥250 tpy

Project Increase at Major Source
(Type 2)
Is Project Increase ≥ PSD Significant Emission Rate?
Project Increase = Planned Emissions - Baseline Actual
6
Example: Base Line (Type 2)
A site is considering a
throughput increase in
2014. What is the baseline
actual emission rate, given
EPN D was built in 2013
with an allowable of 50 tpy?

Planned Emissions
EPN A is operating far below it’s PTE. What are the project increases given
the following?
EPN A Baseline Actual Emissions (BAE)
EPN A Potential to Emit (PTE)
EPN A Projected Actual after project (PAE)
= 61 tpy
= 201 tpy
= 72 tpy
Project increase:
Based on Projected Actual: PAE – BAE = 72 – 61 = 11 tpy
Based on Potential to Emit: PTE – BAE = 201 – 61 = 140 tpy
Use of Projected Actuals may require additional record keeping.

Example: Netting (Type 3)
A company is considering a major project at EPN B that requires netting.
The source has been affected by the following unrelated projects within the
last five years. What is the contemporaneous change?
2010: PTE = 15 tpy
Proposed PTE = 25 tpy
Baseline Actuals = 15 tpy
Project Change: 25 - 15 = 10 tpy
2011: PTE = 25 tpy
Proposed PTE = 25 tpy
Baseline Actuals = 15 tpy
Project Change: 25 - 15 = 10 tpy
2011: PTE = 25 tpy
Proposed PTE = 25 tpy
Baseline Actuals = 15 tpy
Project Change: 25 - 15 = 10 tpy
2014: PTE = 20 tpy
Proposed PTE = 30 tpy
Baseline Actuals = 15 tpy
Project Change: 30 - 15 = 15 tpy
Net: 15 + 10 + 10 + 10 = 45 tpy
