1 SCAQMD REQUIREMENTS FOR LARGE WATER HEATERS AND SMALL BOILERS The Gas Companys Energy Resource Center March 22, 2006

2 Rule – Emissions of Oxides of Nitrogen From Large Water Heaters and Small Boilers The Rule Applies to: 75,000 – 2,000,000 Btu/hr –Type 175,000 – 400,000 Btu/hr –Type 2>400,000 – 2,000,000 Btu/hr

3 Requirements for Manufacturers January 1, 2000 – No manufacture or sales of new Type 2 units (400,000 – 2,000,000 Btu/hr unless: –Certified by AQMD to meet: NOx – 30 ppm or less at 3% O 2, dry CO – 400 ppm or less at 3% O 2, dry

4 Requirements for Manufacturers – cont. January 1, 2002 – No manufacture of new Type 1 units (75,000 – 400,000 Btu) unless: –Certified by AQMD to meet: NOx = 55 ppm or less

5 Requirements for Existing Equipment July 1, Units manufactured before January 1, 1992 (>1MM- 2MM Btu/hr) –Modified (retrofitted) or demonstrate to meet: NOx – 30 ppm or less at 3% O 2, dry CO = 400 ppm or less at 3% O 2, dry

6 Requirements for Existing Equipment – cont January 1, Units manufactured after January 1, 1992 (>1MM – 2MM Btu/hr) –Modified (retrofitted) or demonstrate to meet: NOx – 30 ppm or less at 3% O 2, dry CO = 400 ppm or less at 3% O 2, dry

7 Requirements for Existing Equipment – cont January 1, Units >400, ,000,000 Btu/hr –Modified (retrofitted) or demonstrate to meet: NOx – 30 ppm or less at 3% O 2, dry CO = 400 ppm or less at 3% O 2, dry Units 400,000 Btu/hr or less can operate until replaced by a compliant unit

8 Certification - Manufacturers Use independent testing lab using District protocol Mail test report to: –Moustafa Elsherif Copley Drive Diamond Bar, CA Upon approval of the source test, a certification letter will be issued to the manufacturer Manufacturer required to display certification on the boiler All manufacturers and their certified models will be posted on AQMD website

9 Retrofitting Existing Boilers Use independent testing lab using District protocol Mail test report to: –Moustafa Elsherif Copley Drive Diamond Bar, CA Upon approval of the source test, a certification letter will be issued to the owner

10 Retrofitting Existing Boilers – cont Other requirement for a pre-certified burner –The owner can use Method to determine NOx and CO emissions Using pre-certified burner to same model boiler –The owner can use analyzer to determine the NOx and CO emissions

11 Derating Applicant must obtain a derating certificate from the manufacturer or contractor to show how they achieved the derating and the new derating rate

12 Exemptions From Rule –Heaters/Boilers used in recreational vehicles –Heaters/Boilers used in mobile homes –Heaters/Boilers at RECLAIM facilities –Tankless water heaters From the Requirements –Any residential unit (4 units or less) –Heaters/Boilers using 9,000 therms per calendar year (The Gas Company record or the use of a non- resettable hourly meter)

13 Rule 222 – Filing Requirements For Specific Emission Sources Not Requiring A Written Permit Pursuant to Regulation II Water Heaters/Boilers 1MM to 2MM Btu/hr –The Rule requires a one time filing of Form 222-B for each new certified boiler and a fee of $ per boiler –Retrofitted boiler are required to submit a annual renewal fee
