Reason for Rule Amendment San Joaquin Valley Air Basin is designated: • Federal NAAQS – Nonattainment for particulate matter 2.5 microns in diameter or less (PM2.5). – Extreme nonattainment for eight-hour ozone. California air quality standards Nonattainment for particulate matter 10 microns in diameter or less (PM10). – Severe nonattainment for ozone.
Reason for Rule Amendment • Commitment in District’s 2007 Ozone Plan and 2008 PM2.5 Plan. • Implement control measures through the rule development process and achieve additional reductions of NOx, CO, VOC, and SOx.

No Rule Changes for • Exempt engines. • Agricultural operations (AO) spark ignited engines (NOx, CO, and VOC emission limits) • Compression-ignited engine emission limits/standards. • No change to source testing and recordkeeping
Summary of Draft Amendments • Change rule threshold from >50 bhp to 25 bhp or greater • Lower emission limits for – Non-AO spark-ignited engines. – Non-AO field gas fueled cyclic loaded engines. • Provision for payment of annual fees to comply.
Summary of Draft Amendments • Adding a provision for only one portable NOx measurement, if the engine is operated less than 120 days/year. • Add SOx control and monitoring for Non-AO engines. • Delete existing AECP provision.
Section 5.1: Requirements for Stationary Engines 25 to 50 hp Add a point-of-sale provision: Must • meet federal NSPS for the year in which the engine was last purchased. • By 7/12011, owners of small engines used in Non-AO has to submit a one- time report.
Section 5.2: Requirements for Non-AO SI Engines >50 bhp • Comply with the new emission limits (Table 2 of the draft rule); or • Pay annual fees and comply with the SOx control and monitoring requirements.
Section 5.2 Table 2: Limits for Non-AO Spark Ignited (SI) Engines >50 bhp Effective on and after 1/1/2014 Engine type NOx CO VOC All SI engines, except 11 ppmv 500 30 ppmv ppmv waste gas fueled and cyclic loaded field gas fueled engines Waste gas fueled engines 50 ppmv 2000 250 or 90% ppmv ppmv reduction Cyclic-loaded, field-gas- 25 ppmv 500 250 fueled engines ppmv ppmv
Section 5.6 Payment of Annual Fee • Pay annual fees in lieu of complying with Table 2 NOx limit. • Calculated based on actual fuel used and includes all emissions, not just to rule limits. • Total annual fee includes fee rate, administrative fee, and any applicable late fee. • Fee rate (dollars/ton) is based on the cost effectiveness established in District Rule 9510 (ISR).
Annual Fee Emission Calculation E = [(EF) × (AFU) × (393.2 bhp-hr/MMBtu) × Engine Efficiency] ÷ [453.6 g/lb × 2,000 lb/ton] Where: E = Annual NOx emission for each engine EF = PTO NOx limit in g/bhp-hr AFU = Actual fuel usage in MMBtu/yr Engine Efficiency = 30 percent
Alternative Annual Fee Emission Calculation E = [(EF) × (AFU) x (F factor) × (46 lb/lb-mol) × (O2 factor)] ÷ [379 ft3/lb-mol × 2,000 lb/ton] Where: E = Annual NOx emission EF = PTO NOx limit in ppmv @15% O2 AFU = Annual fuel usage in MMBtu/yr F factor = based on fuel type used O2 factor = 20.95 ÷ 5.95 (correction)
Section 5.9: Portable NOx Analyzer Monitoring for Non-AO SI Engine >50 bhp • Currently requires NOx monitoring each calendar quarter in which a source test is not performed and the engine is operated. • Include a provision to conduct one NOx measurement if the engine is operated less than 120 days per calendar year instead of quarterly.
Section 5.7: SOx Control Requirements • Use on PUC-quality natural gas, commercial propane, butane, LPG, or combination; or • Use CA reformulated gasoline or diesel fuel; or • Use liquid fuel with < 5 grains sulfur/100 SCF; or • Use liquid fuel with < 15 ppm sulfur; or • Use a 95% SOx emission control device.
Section 5.10: SOx Emissions Monitoring • No annual fuel analysis for PUC-quality natural gas, commercial propane, butane, LPG, or combination of such gases, CA reformulated gasoline, CA reformulated diesel fuel. • Annual source test if using an SOx emission control device.
Section 7.7: Table 2 Limits Compliance Schedule • 7/1/2013 – Submit ECP, I&M, and ATC • 1/1/2014 – Demonstrate full compliance with Table 2 limits
Section 7.8: Annual Fees • 7/1/2013 – Submit ECP • 3/1/2014 – First annual fee payment due • 3/1/20xx – Subsequent annual fee due • Late fee applies if payment is not received by specified deadline. • Annual fee payment shall continue until: – Engine is permanently removed or – Demonstrate compliance with Table 2 limits
