Administrative Expectations
The Do’s and Don’ts
Greenhouse Gas Permitting
Administrative Expectations
The Do’s - Submit non-GHG and GHG applications at
the same time:Separate – two PI-1s; orConsolidated – one PI-1
Resubmit if change method
Greenhouse Gas Permitting
Administrative Expectations
The Don’ts - Don’t submit a minor amendment for:
A stand-alone GHG permit; orThe GHG portion of consolidated permit
No minor revisions of GHG permits
Don’t send fee for GHG permit actions

How to Make Your Life Easier
Greenhouse Gas Permitting
Technical Expectations
Consider GHGs as a Pollutant - One of several permitted pollutants
Same importance as NOx, VOC, etc.
Will be permitted with PSD program
Greenhouse Gas Permitting
Technical Expectations
Two Ways to Handle GHGs - 1. Separate Application
2. Consolidated Application
Greenhouse Gas Permitting
Technical Expectations
Separate GHG Application - Two complete applications required:
Don’t cross-reference other applicationNo impacts review or discussion needed
Update both applications in the same e-mail or physical mail
Greenhouse Gas Permitting
Technical Expectations
Consolidated GHG Application - No change in most of application:
Add GHG BACT analysis and calculations
Use only one BACT process
No impacts review or discussion needed
Greenhouse Gas Permitting
Technical Expectations
BACT and GHG - Concept questions
Example
Example questions
Greenhouse Gas Permitting
Technical Expectations
BACT and GHG - Is the process different for GHG?
For example, the use of Carbon Capture and Sequestration (CCS)
What is the BACT determination?A numerical emission limitation, or
if infeasible.....A work practice
Greenhouse Gas PermittingTechnical Expectations
BACT Example (Non-GHG) - Combined cycle (CC) power plant
Fires natural gas
What is BACT for NOX?
Greenhouse Gas PermittingTechnical Expectations
BACT Example (Non-GHG) -How should the application address BACT? Numerical limit – 2 ppm NOX
Based on control device or technique – SCR
No prescribed design or operation of the unit (unless a work practice is BACT)
Greenhouse Gas PermittingTechnical Expectations
BACT Example - Do not propose design and work practices with a numerical BACT. SCR with four catalyst beds using a zeolite
catalyst
One bed will be replaced every year
Ammonia grid design
Greenhouse Gas PermittingTechnical Expectations
BACT Example (GHG) - CC power plant
Fires natural gas
What is BACT for CO2e?
Greenhouse Gas PermittingTechnical Expectations
BACT Example (GHG) - What controls are technically feasible/
economically reasonable?
Can a meaningful numerical limit be set for the turbine?
Greenhouse Gas PermittingTechnical Expectations
BACT Example (GHG) - CCS is not cost effective and may be
technically infeasible for full control of the stack
Efficiency requirements are possible and a numerical limit can be set
Greenhouse Gas PermittingTechnical Expectations
BACT Example (GHG) - Example of BACT for CC power plant:
Turbine Model Gross Heat Rate(Btu/kWh)
Output Specific CO2 Emission Rate (lb CO2/MWh)
Mitsubishi Heavy Industries (MHI) J
7,882 937
Both fuel usage and electrical generation can be measured
Greenhouse Gas PermittingTechnical Expectations
BACT Example (GHG) - Other facilities may express efficiency in different forms.
Exhaust stack temperature
Fuel usage per unit of product
Greenhouse Gas PermittingTechnical Expectations
BACT Example Summary -
Numerical limits speak for themselves.
Implementation and Integration Greenhouse Gas Permitting
Contact Information & Questions
• Issuance• Updates• GHGs• Non-GHGs
Implementation & Integration
Issuance Updates
GHGsNon-GHGs
Greenhouse Gas Permitting
Implementation & Integration
Issuance of Permits – OrderMajor NSR permitting actions for non-GHG and GHG may be issued out of sync. Case-by-case basis
Greenhouse Gas Permitting
Implementation & Integration
Issuance of Permits – TimeframeStart of Construction deadline based on last permit issued. Void process still exists
Issuance timeframes are important
Greenhouse Gas Permitting
Implementation & Integration
Updates to Non-GHG Permits -Non-GHG permit must always be accurate. Amend or alter as needed
No change from past NSR permitting
Greenhouse Gas Permitting
Implementation & Integration
Updates to GHG Permits -GHG permit cannot use minor NSR mechanisms. Updates will be allowed
Guidance is being developed
Must be part of a non-GHG action that is approved with or before the update
Greenhouse Gas Permitting
Implementation & Integration
Updates to EPA-Issued GHG Permits - EPA will rescind if needed (contact EPA)
Updates/major mods through TCEQ
EPA-issued permits receive TCEQ permit numbers
Greenhouse Gas Permitting
Implementation & Integration
Current Issues - When BACT is not a number:
Numerical limit vs. work practiceWork practices can be subjective
Fugitive monitoring for methane
Consistency with non-GHG permit
Updates and existing BACT
Greenhouse Gas Permitting
Implementation & Integration
Moving Forward - Streamlining and standardizing permit
conditions
Documenting more Tier 1 BACT determinations
Working with EPA on TCEQ issued draft permits
