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);

• r
• 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 waste gas fueled and cyclic loaded field gas fueled engines 11 ppmv 500 ppmv 30 ppmv Waste gas fueled engines 50 ppmv

• r 90%

reduction 2000 ppmv 250 ppmv Cyclic-loaded, field-gas- fueled engines 25 ppmv 500 ppmv 250 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
