2. 2 Overview  Senate Bill 1298  DG Certification Program  DG Guidance Document  2005 Technology Review Requirement  Next Steps

3. Purpose is for DG deployment to have minimal impact on air quality Requires emission limits of smaller DG sources to ultimately meet central station power plant limits Requires limits to reflect electricity and useful heat provided Senate Bill 1298 3

4. After January 1, 2003, every DG unit in California either certified by ARB or permitted by district Required ARB to develop certification program for exempt technologies Required ARB to develop guidance document for permitted technologies SB 1298 Requirements 4

5. Applies to manufacturers Applies to new units sold after January 1, 2003 Affects exempted sources Microturbines (Less Than 300 kw) Fuel cells Certification Program 5

6. 6 Certification Program (Continued)  Equipment not affected Emergency standby Portable Zero emission technologies

7. NOx VOC CO Without CHP0.5 1.0 6.0 With CHP0.7 1.0 6.0 2003 Certification Emission Standards (lb/MW-hr) 7

8. NOx VOC CO 0.07 0.02 0.1 2007 Certification Emission Standards (lb/MW-hr) 8

9. 9 What Has Been Certified?  2003 Standards: Two Microturbines  2007 Standards: Two Fuel Cells

10. Assist districts with permitting DG technologies subject to district jurisdiction Create consistent permit conditions and BACT limits for permitted sources Guidance Document 10

11. Applies to DG less than 50 MW Recommended BACT limits for turbines and engines Other recommendations for permit conditions What Does the Guidance Address? 11
