Region 5 Enforcement Approach NACAA Enforcement and Compliance Workshop George Czerniak June 13, 2007
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
ENVIRONMENTAL BENEFIT FROM FY 2006 CAA SETTLEMENTS • Primary Environmental Benefit • Emission Reductions (142,942,912 lbs/yr) • 98,828,033 lbs/yr Sulfur Dioxide • 13,628,951 lbs/yr Nitrogen Oxides • 10,468,625 lbs/yr Volatile Organic Compounds • 9,574,790 lbs/yr Carbon Monoxide • 6,946,758 lbs/yr Carbon Dioxide • 2,326,870 lbs/yr PM10/Particulate Matter • 1,158,218 lbs/yr Hazardous Air Pollutants • 8,588 lbs/yr Chlorofluorocarbons • 2,079 lbs/yr Lead • Federal Penalties Assessed - $4,512,447
PORTION OF ENVIRONMENTAL BENEFIT IN SUPPLEMENTAL ENVIRONMENTAL PROJECTS • SEP Emission Reductions (11,667,767 lbs/yr) • 6,946,758 lbs/yr Carbon Dioxide • 4,071,210 lbs/yr Carbon Monoxide • 240,033 lbs/yr Sulfur Dioxide • 233,398 lbs/yr Hazardous Air Pollutants • 130,748 lbs/yr PM10/Particulate Matter • 26,951 lbs/yr Nitrogen Oxides • 15,425 lbs/yr Volatile Organic Compounds • 2,079 lbs/yr Lead • 1,165 lbs/yr Chlorofluorocarbons
TARGETING APPROACH Theory of Violation Develop Expertise Work Through Company, Sector, Rule
ACID PRODUCTION THEORY: NSR
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
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
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 THEORY: NSR
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
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)
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)
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%)
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
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 THEORY: WRONG PERCEPTIONS
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
