Permitting Improvements – GPs
Aggregate Industry GP Development
Have spent last 2 years developing GPs for typical quarry operations
Includes: Compression ignition (diesel) engines (12) Mineral Extraction (1) Permanent aggregate processing plants (1) Portable aggregate processing plants (1)
15 different GPs
Aggregate Industry GP Development
Multiple rounds of comments/revisions with industry/others
Multiple updates to NSPS/MACT caused multiple revisions
Changes in BAT caused other revisions
Compression Ignition Engine GPs
October 26 issued 12 Model General Permits for comment
Multiple groups of compression ignition (diesel) engines
Range from 50 to 1100 HP
Compression Ignition Engine GPs
Multiple variations that follows NSPS Subpart IIII and MACT Subpart ZZZZ
See: http://www.epa.ohio.gov/dapc/genpermit/genpermits.aspx for details
Comment period closed November 29. Hope to have final early 2011 Contact Cheryl Suttman
Extraction and Processing GPs
Received comments from IP Made revisions including SB265 changes Currently with industry group for final
comments Hope to have IP out in December Hope to have final in 2011
Future GPs
Have group started for biomass digester facilities
Goal is to get developed early 2011 Expect to see multiple applications this
spring Currently working on initial draft terms Jenny Avellana is the lead contact
Other GP issues
Will need to update several GPs due to SB265/MACTs/rule changes
Have not yet gotten “volunteers” to work on these.
Permitting Improvements – PBRs
Revised 31-03 to: Update PBR for small and mid-size printing
facilities Revise emergency generator/air
compressor/water pump exemption and PBR to allow use emergency load response programs
Effective Thursday, August 26th, 2010
Ohio NSR Reform Rules
02/25/10: U.S. EPA approves Ohio NSR Reform rules (75 FR 8496)
Originally filed October 2004 Now a part of our SIP
Update on PM2.5 Rule Changes
Feds issued revisions May 2008 Ohio EPA issued guidance in August 2008 DAPC issued IP rule package April 24,
2009 Need to finalize changes/revise per other
issues
Update on PM2.5 Rule Changes
10/20/10 U.S. EPA finalized PM2.5 PSD changes PSD Increments (Eff. 09/29/11???) Significant Impact Levels (start using) Significant Modeling Thresholds (start using)
Plan to incorporate into our PM2.5 rules
Update on PM2.5 Rule Changes
What about condensables? Methods 201A and 202 still not revised Feds working on Other Test Methods
OTM 27, (Constant Sampling Rate Procedure) OTM 28, (Dry Impinger Method)
Continue using August 2008 OEPA memo Exclude condensable for limits Collect condensable info
OAC rule 3745-21-09(U)(2)(f)
02/22/10 U.S. EPA proposed approval of past (U)(2)(f) approvals
No comments received Finalized 06/21/10 (75 FR 34939) Allows us to use new procedure for U2f
(U)(2)(f) Procedure
Company submits PTI application w/U2f study (similar to BAT/BACT study)
Ohio EPA sends study to U.S. EPA U.S. EPA reviews concurrent to Ohio EPA Ohio EPA issues draft
(U)(2)(f) Procedure
U.S. EPA OK’s issuance of final Ohio EPA issues final Ohio EPA submits U2f portion of permit to
U.S. EPA for SIP Work closely with CO permit contact
BAT Update
BAT began with permit program 1974 Key part of Ohio’s plan for 36 years Designed to ensure new sources install
state-of-the-art controls or use state-of-the-art methods
Historically has been a case-by-case determination
SB 265 implements significant changes to BAT
Short History
SB 265
SB 265 authors wanted certainty concerning BAT
Did not like not knowing BAT before applying for permit
After SB 265 became effective (08/06), Ohio EPA began working on revisions
Some rule revisions effective 12/06 Others were being worked on.
<10 ton/yr BAT Exemption
Modified OAC rule 3745-31-05, Criteria for Decision by the Director
Established exemption for <10 ton/yr controlled sources
DAPC began issuing permits w/o BAT for <10 ton/yr sources
Ohio EPA submitted SIP revision to USEPA
December 1, 2006 BAT Changes
U.S. EPA not yet supportive of SIP revision (Currently not in SIP)
Concerned change is backsliding Ohio EPA must show why not backsliding Difficult to prove See attached 06/05/08 U.S. EPA letter
<10 tons/yr Exemption Problems
Sierra Club filed suit to U.S. District Court, Southern District
Claims: Adopting and enforcing requirements less
stringent than SIP Anti-back sliding Failure to properly notice Failure to submit SIP support
Significant litigation time
Sierra Club v. Korleski
02/02/10 Magistrate Able grant’s Sierra Club's Motion for Reconsideration
Director can’t use BAT exemption until approved as part of federal SIP
See attached decision
Sierra Club v. Korleski
Ohio EPA suspends permit issuance for new and renewal sources
Ohio EPA drafts guidance
02/19/10 Ohio EPA issues guidance on <10 ton exemption issue
Ohio EPA Response
Can now issue installation permits (PTIs, PTIOs)
Must determine case-by-case BAT for all sources including <10 ton sources (no exemption allowed)
Write “dual” language term for the <10 ton sources.
Applies to new or modified, not yet renewals
<10 ton Exemption Guidance
Paragraph 1 Describes BAT using SIP-approved rule
(11/30/01 version of OAC Chapter 31) Describes that BAT no longer applies once
<10 ton rule is SIP approved Paragraph 2 – describes why BAT does
not apply once the <10 ton rule is SIP approved
See February 19, 2010 Permit Processing Memo page 2-3
Dual Language Terms
>=10 ton BAT
Memo issued December 10, 2009 Follows SB 265 approach BAT = MACT, BACT or LAER… If not, then BAT = RACT… If not, then case-by-case BAT
Post 08/03/09 BAT
Review 12/10/09 BAT Requirements Memo
Check to see if MACTs, BACT, LAER applies
If so, then establish BAT If not, then review RACT
rules
How do you determine BAT?
BACT,LAER ,MACT
Review 01/01/06 version of Chapter 21 for VOC limits
VOC limits apply anywhere in the state to the same size and type of source?
If so, then find most stringent, establish limit as BAT for VOC
If not, then move on to case-by-case approach for VOC
RACT Rule Review for VOC and NOx
RACT
Review existing OAC Chapter 110 (Nitrogen Oxides – Reasonable Available Control Technology rules)
NOx limits apply anywhere in the state to the same size and type of source?
If so, then find most stringent, establish limit as BAT for NOx
If not, then move on to case-by-case approach for NOx
RACT Rule Review for VOC and NOx
Step one – complete past case-by-case analysis for BAT (i.e., looking at similar source, cost-effectiveness etc.) for each criteria pollutant and each operating scenario
Determine past BAT
Case-by-Case BAT
Case-by-Case
Step two – determine the format for the limit Review BAT Emission Limit
Format Table for similar source Locate pollutant for the source,
then BAT Limit Format Convert the above limit into the
BAT limit format
Case-by-Case BAT
Case-by-Case
Uncontrolled Combustion Turbine
Determined past BAT was 5.7 lbs PM/hour uncontrolled
Find “combustion Turbine” in BAT Emission Limit Format Table
Case-by-Case BAT Format Example
Find PM for uncontrolled situation
Table says limit format should be X pounds PM/mmBtu
Convert 5.7 lbs/hr limit to lb/mmBtu limit
Case-by-Case BAT Format Example
BAT is determined to be the numerical limit in the determined format
Must do same approach for each criteria pollutant emitted in significant amounts
Must do same approach for each operating scenario
Only one BAT limit for each pollutant for each operating scenario
Case-by-Case BAT
Will need rules – memos not sufficient Will need to get in SIP… U.S. EPA will
need to approve Prescriptive approach on hold Court actions add to uncertainty Unclear when rules will be written
>10 ton/yr BAT Rule Status

Expect changes to occur
We will let you know when we know
