IPM and ERTAC show large differences
in SO2 emissions in many states.
In most cases, ERTAC showed higher SO2 emissions although it is not
always true.

LADCO/ERTAC EGU Timeline
• March 2015 – LAST ERTAC Comment period.
• LADCO builds 2.4L with updates from states, Used to respond to
Transport rule – December 2015
• March 4th – MATS Updates Due. LADCO Creates 2.4Lv2 with Updated
Growth rates to reflect current conditions.
• March 2016 – LADCO delivers early inventory for Ohio PM SIP.
• April 15th, ERTAC Comment period closes for stakeholders.
• ERTAC group releases milestone version 2.5 May 2016.
• Summer 2016. Version 2.6 of ERTAC released.
Near Term ERTAC Plans
• Summer Comment Period for Version 2.6
• July 20th call with stakeholders with early August Due Date for comments
• August 3rd States call with early September due date
• Gives more time for states to respond to stakeholder comments,
ERTAC will not include stakeholder comments until states approve.
• October/November release date of 2.6
• Include new AEO growth rates
• New source code(Inter-regional swaps, fewer Demand Deficit units)
• Add CSAPR budgets. That could be challenging in some states.
MATS Compliance Modeling
• EPA has assumed units will comply with MATS by meeting .20
LB/MMBTU SO2
• ERTAC has used less aggressive assumptions in past. This has included
20% reduction in SO2 rate for units where direct control data does
not exist.
• ERTAC asking for States/stakeholders to fill in attached sheet to clarify.
• Fill in last 3 columns with MATS Compliance status.
• Provide control information in column AK if data in AD does not
reflect compliance level. Show expected actual rate not permit limit.
• Email to [email protected] by March 4th.

Understanding the Difference Between IPM
and ERTAC
• IPM is a least cost economic model. It is attempting to find the least
cost solution for future year generation. It is important for EPA to
understand the future economic costs of control measures.
• ERTAC is a pattern duplicating projection tool that is designed to
create an emissions conservative projection of future year emissions
ready for CTM Models and State SIPS. It is important for states to be
able to justify controls and shutdowns they use in their SIPS.
• Those differences in approach largely explain the differences in
results.
Why do we care about differences?
• In the past EPA has defined budgets for transport rules based
current methods.
• Those budgets can result in “winners” and “losers” in
budgets where some states have a disproportionately
difficult budget.
• States still must meet those budgets regardless of equity.
• Cost to operate the models vary significantly, Proprietary pay per run vs maintain a standing committee. Would states
do this without ERTAC, It is likely that states would need last
minute runs for last minute changes.

Contribution Differences
Temporal Differences
• Questions:
• Are they likely to change contributions (i.e., “linkages”)
• Are they likely to change the DVs such that a monitor is no longer a receptor.
• Would the differences make it more or less likely a receptor could be resolved at a
lower cost threshold with fewer emission reductions?

#2 Use of IPM and ERTAC in SIPS
• Clarify Existing Guidance and Documentation Requirements
• Background Material
• Model Inputs
• Standardized reports
• What should be done about unexpected Shutdowns/Controls in state SIPS.
• Rerun IPM?
• How can states/MJOs discuss problematic SIP requirements from Regions.
• Operational Constraints of using the two models, Run costs with IPM, Staff
training and costs with ERTAC.
• SIP impacts of optimistic or conservative results.
• How to model trading program “Budgets” (actual budget level, equalized
fuel/rate level, assurance levels, or ??)
#3 Modeling Controls Beyond OTB.
• How do both models include control scenarios
• How should CSAPR Budgets be modeled/evaluated
• Shutdowns that don’t happen?
• Controls that are not built.
• Trades and trading limits
• Attribute differences between control scenarios with ERTAC and IPM.
• How do economics change results of strategy modeling?
• Controls that force shutdowns
• Economies that reduce dependency on certain units, fuels, or states.

#4 Using models to build budgets
• What are the problems of creating budgets with the two tools.
• How do we minimize discontinuity and inequity in budgets.
• What are the elements of existing budgetary methodologies that
cause problems and how to minimize them.
• Critique the process before future budgets are released because after
release conversation is pitting winners against losers in the economic
simulation that resulted in that budget.
