  1. 2003 Hot Spots Annual Report • Program Overview • Four Basics: Quantify, Assess, Notify and Reduce • Significant Risk Sources – Success! • Five “Significant Risk” Businesses Remain of original 51 • Risk Reduction Due Dates and Risk Assessments • Notification of Public • Upcoming Efforts

  2. Hot Spots Basics • Program approved by Legislature in 1987 • Initially, a Public “Right to Know” Law • Amended Since to Require Risk Reduction • Requires facilities to: • Quantify Air Toxics Emissions (730+ compounds) • Assess Offsite Impacts of Emissions • Notify Neighbors if Emissions Pose Significant Risk • Reduce Risk to Less-than-Significant Level • Notification and Significant Risk levels established by APCD Board

  3. Significant Risk Sources • Five Significant Risk facilities remain from original 51 – a 90% reduction since early 90’s • Carpinteria Oil and Gas Plant (Venoco) • Ellwood Oil and Gas Plant (Venoco) • Santa Maria Refinery (Greka) • Cat Canyon Lease + UCB/Dominion Lease (Greka) • Zaca Field Lease (Greka) • Risk Reduction dates established for each facility • APCD working with each operator • Health Risk Assessments to confirm reduced risk

  4. Significant Risk Sources– cont. • Public Notification in Fall, 2004 • Based on revised Health Risk Assessments that account for: • Updated toxic emissions information • Implementation of risk reduction measures • Facilities with Significant Risk must Notify • Enforcement action may also result for those that have not reduced by due date

  5. Upcoming Efforts • Oversee Risk Reduction, HRAs and Notification for Significant Risk sources (Summer & Fall, 2004) • Database integration (toxics, emissions, permitting) – allow for quick HRAs, simplified data submittal by operators (2004) • Small source toxics assessments – body shops, dry cleaners (2004/2005) • Integration of diesel engines into Hot Spots program – quantify, assess, notify and reduce (2004/2005+)

  6. Summary • Hot Spots Program • Public “Right to Know” and Risk Reduction Law • Program has been successful • 90% reduction in Significant Risk sources • Five remaining sources working to meet due dates • Updating inventories and risk assessments; Notification may be required in Fall • Future Efforts to address risk reduction & notification, database integration, small source assessments, diesel engines

  7. Ellwood Facility (Venoco) • Significant Risk from… • PAH, Benzene: cancer risk = 53/million (> 10/million) • Hydrogen sulfide: acute non-cancer risk = 21 (HI>1) • Hydrogen sulfide: chronic non-cancer risk = 2.3 (HI>1) • Risk Reduction measures • Reassess offsite risk after… • “zoning” of plant & recalculating fugitive emissions • speciation of PAH • Risk Reduction due date: July, 2004

  8. Carpinteria Facility (Venoco) • Significant Risk from… • PAH : cancer risk = 14/million (> 10/million) • Acrolein : chronic non-cancer risk = 8 (HI>1) • Risk Reduction measures • Eliminate marine vessel usage at pier • Reevaluate acrolein emissions • Investigate and install post-control equipment • Investigate emerging emission reduction options • Risk Reduction due date: July, 2004

  9. Santa Maria Refinery (Greka) • Significant Risk from… • Benzene : cancer risk = 21/million (S/R > 10/million) • Hydrogen sulfide: acute non-cancer risk = 18.2 (HI>1) • Risk Reduction measures Reassess offsite risk after… • Refined fugitive emissions evaluation • Risk Reduction due date: August, 2006

  10. Zaca Field Lease (Greka) • Significant Risk from… • PAH : cancer risk = 23/million (S/R > 10/million) • Hydrogen sulfide: acute non-cancer risk = 4.5(HI>1) • Risk Reduction measures Reassess offsite risk after… • Speciation of PAH • Refined fugitive emissions evaluation • Revision of onsite H2S emissions • Risk Reduction due date: July, 2004

  11. Greka Cat Canyon Source • Greka properties in Cat Canyon oil field • Cat Canyon: 1999 • UCB/Dominion: 2000 • West Cat Cyn: 2002 • US Hwy 101 in lower left
