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

2. Hot Spots Basics Program approved by Legislature in 1987 Program approved by Legislature in 1987  Initially, a Public “Right to Know” Law  Amended Since to Require Risk Reduction Requires facilities to: 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 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 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 Risk Reduction dates established for each facility APCD working with each operator APCD working with each operator Health Risk Assessments to confirm reduced risk Health Risk Assessments to confirm reduced risk

4. Significant Risk Sources – cont. Public Notification in Fall, 2004 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) 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) 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) 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+) Integration of diesel engines into Hot Spots program – quantify, assess, notify and reduce (2004/2005+)

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