The Case for Change
What’s Going on with NSR? 4

The Case for Change
The time required to obtain a permit is unreasonably long and varies across the country
~45% of industry NSR permits > 1 year to process
Range 1 month to 7.5 years.
14 month average
Rule complexity and uncertainty
95% of refining capacity has entered into settlement agreements since March 2000
112 refineries in all, at present
NSR was a primary issue in the vast majority

Bill Wehrum on NSR Reform
What’s Going on with NSR? 7
BNA Energy and Climate Report (November 27, 2017)
“I'm not so sure full-scale reform is what we need to do. The analogy I use is we're going to try to hit a few singles, maybe a couple of doubles, but we're not going to swing for the fences . . . ” “If we do enough of these more
targeted things, then I think over time we will have a big impact on the program.”

A New Approach to ATPA
www.erm.com
Actual-to-Projected-Actual Applicability Test
December 7, 2017 - Guidance memorandum titled “New Source Review Pre-construction Permitting Requirements: Enforceability and Use of the Actual-to-Projected-Actual Applicability Test in Determining Major Modification Applicability.”
New approach to EPA enforcement regarding the ATPA Test
EPA will not “substitute its judgment for that of the owner or operator” concerning a source’s emissions projections, unless there is clear error.
Projections may include intent to actively manage post project emissions
Enforcement focus will be on post project emissions
Use of demand growth exclusion is explicitly recognized and allowed
What’s Going on with NSR? 10
Source Aggregation Guidance

Aggregation – The Updated 3-Part Test
What’s Going on with NSR? 12
www.erm.com
Two Key Updates
1. April 30, 2018 Meadowbrook Energy Source Determination – Addressing the term “Common Control”. Control means the power to dictate decisions impacting compliance.
2. September 4, 2018 Draft Guidance – Interpreting “Adjacent” for New Source Review and Title V Source Determinations in all Industries Other Than Oil and Gas
A. Adjacency solely based on proximity
B. No bright line rather “Nearby” is the test
C. Functional Interrelatedness is not a factor

Project Aggregation Rule (w/ OMB since July 6th)
www.erm.com
What is Project Aggregation?
What’s Going on with NSR? 16
Should two separate projects be combined into a single permit application rather than permitted individually?
Project A Project BJanuary 201730 tons per year VOC
November 201725 tons per year VOC
www.erm.com
What Has Been Historic Approach to Project Aggregation?
What’s Going on with NSR? 17
Historic approaches established through guidance memos
January 2009 final rulemaking
under Bush administration withdrawn by Obama EPA
Further defined under previous administration -
“case by case” determination based on
multiple factors
Guidance memos
Bush final rulemaking
Back to historic
guidance docs
www.erm.com
What is Happening Now?
What’s Going on with NSR? 18
Projects should be combined that are “substantially related”Have more in common than simply supporting the overall basic function of the facility
0201
03Approach expected
to be similar to 2009 rulemaking
EPA has drafted rulemaking which is currently under OMB review
Projects presumed to be separate if they are three or more years apart
March 13th NSR Project Emissions Accounting Guidance

Project Emissions Accounting
What’s Going on with NSR? 20
1 2 3New
CT/HRSG
Project Description:• Construct New CT/HRSG• Remove Boiler #1
Emissions Increase due
to Natural Gas Combustion
Emissions Decrease due
to Boiler 1 Removal
Scope of Step 1 significant emissions increase evaluation under previous guidance – all shutdown credits in Step 2Current guidance allows shutdown credits that are part of the project
www.erm.com
Project Background
Source Description: University with central powerhouse for steam and electric generation
Proposed project:
Construct new natural gas-fired CT/HRSG
Remove existing coal-fired spreader stoker boiler (Boiler 1)

NSR Reforms in Proposed ACE Rule
www.erm.com
What Triggers NSR
What’s Going on with NSR? 25
NSPS – Will it result in any increase the maximum achievable hourly emissions
NSR – Will it result in a significant increase in actual annual emissions
A modification is “any physical change in, or change in the method of operation of, a stationary source which increases the amount of any air pollutant emitted by such source.”
www.erm.com
Major Issues with NSR Annual Test
What’s Going on with NSR? 26
Very subjective Many things affect annual emissions
According to EPA:• Replacing components (even with identical components) will
almost always cause an increase in annual emissions• Improving the efficiency of a plant will almost always cause
an increase in annual emissions
www.erm.com
NSR Reform Proposed for EGUs in ACE Rule
What’s Going on with NSR? 27
Will the project result in an increase in maximum hourly emissions? (Some version of the current NSPS test)
If so, will the project result in a significant increase in actual annual emissions? (The current NSR test)

Issues to be Resolved
What’s Going on with NSR? 28
Achieved vs. Achievable
01
What’s the baseline?• Highest hour in last
year? 5 years? 10 years?
• Statistical Approach (e.g. Upper Tolerance Limit)
• Hourly rate averaged over a representative period. 24 hours? A week? 30 days?
