8. Air Resources Board Emission Inventory Workshop Spring 20068 State Health and Safety Code ARB has responsibility for development of State Implementation Plans (Section 39602) ARB must inventory all sources of air pollution and use local agency data to fullest extent possible (Section 39607(b)) Districts have power to require facility operators to provide emission inventory data (Section 40701(g))

9. Air Resources Board Emission Inventory Workshop Spring 20069 California Clean Air Act Adopted in 1987 Requires all areas of the State to attain state standards as soon as possible (all feasible measures) Limited to criteria pollutants Authorizes ARB to require districts to impose fees on sources > 250 TPY of any nonattainment pollutant Authorizes ARB to impose fees on consumer product and architectural coating manufacturers that sell a product in California resulting in emissions > 250 TPY of VOC

10. Air Resources Board Emission Inventory Workshop Spring 200610 AB 2588 “Hot Spots” Act Passed in 1987 Limited to toxics pollutants Objective is to reduce toxics risk from individual facilities Includes public notification process Quadrennial reporting schedule Fee schedule adopted to support program Risk-based program (i.e. not emission-based)

11. Air Resources Board Emission Inventory Workshop Spring 200611 ARB Environmental Justice Policies Adopted in 2001 In response to SB 115, EJ must be considered in development, adoption, implementation, and enforcement of environmental laws and regulations ARB must assess, consider, and reduce cumulative emissions, exposures, and health risks

12. Air Resources Board Emission Inventory Workshop Spring 200612 Federal Clean Air Act Amendments Passed in 1990 Limited to criteria pollutants Affects states with nonattainment areas Requires submittal of comprehensive, accurate, and current emission inventories as revisions to SIPs

13. Air Resources Board Emission Inventory Workshop Spring 200613 Federal Consolidated Emissions Reporting Rule CERR adopted in 2002 Limited to criteria pollutants Large point sources must report annually (threshold varies) All other sources must report every three years 2002 inventory submitted June 1, 2004 2005 inventory to be submitted June 1, 2007

14. Air Resources Board Emission Inventory Workshop Spring 200614 Air Emissions Reporting Requirements Replaces CERR Rule to be phased in by 2011 Accelerated reporting schedule to EPA e.g. 2010 data would be due on June 30, 2011 Until 2011, EPA plans on scaling back the requirements under the CERR

Air Resources Board Emission Inventory Workshop Spring 200618 Point Source Toxics Reporting Report high-risk facilities annually Risk 1 in a million; or 10 TPY of any single HAP; or 25 TPY of any combination of HAPS Report AB2588 facilities annually Needed for toxics inventory, HARP, Community Health, CHAPIS, NEI

19. Air Resources Board Emission Inventory Workshop Spring 200619 Criteria for Facility Updates Missing and incorrect data emissions, codes, spatial Change in criteria emissions 5% or 10 TPY change Change in toxics emissions 10% change in process rate Addition or removal of device or process since last year

20.
