1-Hr Summary
• LSU monitor already has 3 hits for 2005• Capitol, Port Allen, and Carville have 2
Exceedances in 2004 and 2005 (especially at LSU) are crucial or the area will be out of attainment in 2005 – the Clean Air Act attainment year.

Re-Classification to Severe
• BR was originally classified serious with an attainment date of 1999.
• Modeling showed that the area was being affected by ozone transport from Houston.
• Under EPA guidance, an extension to 2005 was granted based on transport.
• Under pressure EPA pulled the approval and the area was bumped-up to severe with a 2005 attainment date. (June 23, 2003)
![Page 9: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/9.jpg)

Consequences of Bump-Up
• Definition of major source reduced from 50 tpy to 25 tpy for both NOx and VOC (revise Chapters 21 and 22)
• Offset requirements increase to 1.3 with LAER and 1.5 to avoid LAER (Lowest Achievable Emission rate)
• Reformulated Gasoline (RFG)• Section 185 fees for failure-to-attain by2005
![Page 10: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/10.jpg)

Section 185 Fees (rule in comment period until 4/2)
• Fees start in 2007 (for 2006) and continue until the area is in attainment
• Exemptions: (EPA opposed, no exemptions) if equipped with minimum 95% control; or if equipped with BACT• Baseline is the average of annual emissions
of VOC and NOx from non-exempt sources for the most representative 3 years between 1998 and 2002. (EPA opposed, must be 2005)
![Page 11: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/11.jpg)
11
Section 185 Fees (continued)
Fee = [A-(80% x B)] x C A = Total actual VOC and NOX emissions
in previous year from non-exempt sources B = Baseline amount (tons) C = $5,000 per ton adjusted by CPI to
subject year (approximately $8,000)

Chapter 22 NOx Rule
• Promulgated March 2002• Applicable in 9 parishes during ozone season• Establishes emission factors for boilers, heaters,
furnaces, turbines and engines• Sources must be in compliance by 5/1/05• Average point NOx reduction is 30%• Model shows attainment in 2005
Revision for severe classification by June 23
![Page 13: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/13.jpg)

HRVOC Workgroup
• 1-hour ozone design value has dropped from around 170 ppb in the early 90s to the low 130s ppb today
• VOC and NOx have been dropping steadily since the early 90s
• See VOC and NOx graphs

HRVOC Workgroup (continued)
• Continuing to have exceedances (11 in 03)• Plot shows rapid ozone formation events
(greater than 40ppb/hr rise) - see graph• Similar spikes in Houston, Texas 2000 Air
Study implicated HRVOC – 1,3-butadiene, acetaldehyde, butenes, ethylene, propylene, toluene and xylenes

HRVOC Workgroup (continued)
• Workgroup (DEQ, Industry, Environmentalists) formed to evaluate role of HRVOC.
• Recommendations: Add NOx at Dutchtown, Met at LSU and Carville Add continuous VOC at LSU, Capitol, Carville Add VOC canister every 6th day at others Record 5 minute data in addition to 1 hour average Develop database for past and future data, perform
statistical analyses

HRVOC Survey
• Purpose was to identify sources of HRVOC (TEDI-toxics, EIS-total VOC, TRI-facility)
• Sent to 148 facilities in BR area• 62 met criteria of >1,000 lbs/yr HRVOC
emissions and submitted information• Results: See graphs

Action Plan for Summer 2004
• Review Environmental Management System Are all emissions being accounted for? Can emissions be lowered by reducing at
source, recycling, recovery or treatment? Are measured values being used, where
available, to estimate the quantity of emissions? Are the latest and best factors and estimation
methodologies being used?
![Page 26: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/26.jpg)
26
Action Plan for Summer 2004 (continued)
• Fugitives – before Summer - consider remote imaging to survey regulated and non-regulated components where HRVOC could leak, make extraordinary attempts to fix tagged leakers
• Flares – always operate within design, delay discretionary flaring to evening
• Cooling Towers – check inlets weekly for HRVOC, fix leaks as soon as possible
• Wastewater – reduce HRVOC wherever possible
![Page 27: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/27.jpg)
27
Action Plan for Summer 2004 (continued)
• Analyzer Vents – route to flare or minimize• Shutdowns – do early or postpone until after
ozone season• Maintenance/Equipment Opening – delay
until evening, refueling in late evening• Seasonal Activities – delay painting until later
in year, do grass cutting in evenings, etc.
![Page 28: Presentation to Industry Action Plan for Summer 2004 April 1, 2004](https://reader036.vdocuments.us/reader036/viewer/2022070419/56815cda550346895dcae42f/html5/thumbnails/28.jpg)

Summary
• Ozone exceedances in downtown BR in 2004/05 will put the area out of attainment.
• If this happens, emission fees will kick-in.• Facilities are asked to develop action plans
to reduce emissions, especially HRVOC, but also, other VOC and NOx.
