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
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
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
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
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+)
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
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)
