Region 5 Enforcement Approach
George CzerniakJune 13, 2007
NACAA Enforcement and
Compliance Workshop

TARGETED INVESTIGATIONS
• Don’t Try for Broad Coverage• Don’t Affirm Compliance• High Likelihood of Violation Where
Correction Will Result in Significant Emission Reduction
• Focus on Company, Sector, Rule

ACID PRODUCTION
• Remedy– Sulfuric Acid Plants
• Wet Gas Scrubber• Double Contact Double Absorption System
Capable of Meeting an Emissions Limit of 1.5 lbs/ton
• Mist Elimination System Capable of Meeting Sulfuric Acid Mist Emission Rates of 0.15 lbs/ton or less
![Page 13: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/13.jpg)
13
ACID PRODUCTION
• Remedy (cont.)– Nitric Acid Plants
• Selective Catalytic Reduction (SCR)• Non-Selective Catalytic Reduction (NSCR), and/or• Extended Absorption System• Capable of Meeting NOx Emission Limits in the
Range of 0.3 to 0.6 lbs/ton
![Page 14: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/14.jpg)

ACID PRODUCTION
• Potential Environmental Results– 120,000 TPY of SO2
– 30,000 TPY of NOx• Current Status
– Two (2) Settlements• 6 Sulfuric Acid Plants• 1 Nitric Acid Plant
– Reductions:• 19,000 TPY SO2
• 200 TPY NOx• Sulfuric Acid Mist Reductions
– Settlement discussions continue with others

PETROLEUM COKE

16
PETROLEUM COKE
• Affected Sectors– Cement– Iron and Steel– Coal Fired Boilers– Calcining
• Remedy – SO2 (Scrubbers) – NOx (SCR and SNCR) Controls
• Potential National Environmental Results– 160,000 TPY SO2 and NOx Reductions
• Current Status– One Global Negotiation in Progress, One On-going
Case, Two Investigations

FLARING
THEORY:LESS SCRUTINY
FOCUS ON OPACITY
![Page 18: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/18.jpg)
18
FLARING
• Proper Operation– Pilot flame must be present– Sufficiently low exit velocity– Smokeless operation
• Steam or air commensurate with organics– Heat Content > (300 BTU/scf)
![Page 19: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/19.jpg)
19
FLARING
• Regulations – MACT
• General provisions 63.11(b)• Polymers & Resins, HON, Pharmaceuticals,
Refineries, etc.– NSPS
• General Provisions 60.18(b)• SOCMI, Polymers, Refineries, etc.
– SIP• State VOC reduction requirements• State permit requirements (e.g. 300 BTU)
![Page 20: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/20.jpg)
20
FLARING
• Violations– Heat Content lower than 300 BTU/scf
(63.11(b), 60.18(b))– Failure to use good air pollution control
practices by steam addition in excess of design parameters (63.6(e), 60.11(d))
• Specified by API and Flare Manufacturer• Typically near 1 lb steam/1 lb gas
– Destruction Efficiency Specified in SIP (95%)
![Page 21: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/21.jpg)
21
FLARING
• Remedy– Heat Content (BTU/scf) Instrument– Steam Addition Control Valve– Natural Gas Addition Control Valve– PLC So Heat Content Dictates Steam and
Natural Gas Addition Rates• Potential Environmental Benefits
– Increase In Destruction Efficiency at the Flare– Less VOC and HAPs Emissions
![Page 22: Region 5 Enforcement Approach](https://reader036.fdocuments.in/reader036/viewer/2022062411/56816790550346895ddcc193/html5/thumbnails/22.jpg)
22
FLARING
• Current Status– Batch Chemical Plant in SW Ohio
• 300 BTU/scf and oversteaming violations• NOV issued• > 560 TPY excess emissions
– Batch Chemical Plant in NW Ohio• 300 BTU/scf and oversteaming violations• NOV issued • ~ 12 TPY excess emissions
– Batch Chemical Plant in SE Ohio• $675,000 instrument upgrade for two flares in response to an
information request • < 5 TPY excess emissions

CEM
• Remedy– Continuous compliance– Fixing causes of excess emissions/CEMS downtime so
they don't happen again– Injunctive relief (redesigned/new control technology to
replace old/underdesigned controls)– SEPS
• Current Status– Seven Notices/Findings of Violation– ~ 100 Facilities Being Reviewed
