## Standard Operating Permit Condition XI – SO 2 

## Emissions from Oil Fired Fuel Burning Equipment

Emission Unit [SOURCE] or Stationary Source [FACILITY] Categories This Condition Applies to: Any fuel burning equipment using liquid fuel.

The department will use standard permit c ondition XI in any operating permit unless the department determines that emission unit [SOURCE] or stationary source [FACILITY] specific conditions more adequately m eet the requirements of 18 AAC 50.

Circumstances where emission unit [SOURCE] or stationary source [FACILITY] specific conditions more adequately meet 18 AAC 50 include:

1. if an alternate monitoring plan for sulf ur emissions has been approved for the equipment under a New Source Performance Standard;

2. at a petroleum refinery;

3. if an alternative plan fo r sulfur emissions is approved for the equipment under a construction permit.

Permit Wording:

1. Sulfur Compound Emissions. In accordance with 18 AAC 50.055(c), the permittee shall

not cause or allow sulfur co mpound emissions, expressed as SO 2 , from <insert

identification of emission units [SOURCES]> to exceed 500 ppm averaged over three

hours.

2. Sulfur Compound Emissions – Moni toring and Record Keeping.

2.1 The permittee shall do one of the following for each shipment of fuel:

a. if the fuel grade requires a sulfur content less than 0.5% by weight, keep receipts that specify fuel grade and amount; or

b. if the fuel grade does not require a su lfur content less th an 0.5% by weight, keep receipts that specify fuel grade and amount and

(i) test the fuel for sulfur content; or

(ii) obtain test results showing the sulfur content of the fuel from the supplier or refinery; the test results must in clude a statement signed by the supplier or refinery of what fuel they represent.

2.2 Fuel testing under condition XI.2.1 must fo llow an appropriate method listed in 18 AAC 50.035 or another method approve d in writing by the department.Standard Operating Permit Condition XI –

SO 2 Emissions From Oil Fired Fuel Burning Equipment 2 April 1, 2002 Revised August 25, 2004 2.3 If a load of fuel contains greater th an 0.75% sulfur by wei ght, the permittee shall

calculate SO 2 emissions in PPM using either co ndition <insert cross reference to standard permit condition XII - SO 2 material balance calcul ation> or Method 19 of 40 C.F.R. 60, Appendix A-7, adopted by reference in 18 AAC 50.040(a).

3. Sulfur Compound Emissions – Reporting . The permittee shall report in accordance with

this condition XI.3.

3.1 If SO 2 emissions are calculated under condition XI.2.3 to exceed 500 ppm, the permittee shall report under condition <insert cross refe rence to standard permit

condition III - excess emissi ons and permit deviation re ports>. When reporting under this condition XI.3.1, include the ca lculation under condition <insert cross reference to standard permit condition XII - SO 2 material balance calculation>.

3.2 The permittee shall include in the repor t required by condition <insert cross reference to standard permit condition VII - operating reports>

a. a list of the fuel grades received at the stationary source [FACILITY] during the reporting period;

b. for any grade with a maximum fuel sulf ur greater than 0.5% sulfur, the fuel sulfur of each shipment; and

c. for fuel with a sulfur content greater than 0.75%, the calculated SO 2 emissions

in PPM.

4. Sulfur Compound Emissions – North Slop e – Monitoring, Record Keeping, and Reporting. For liquid fuel from a North Slope to pping plant, the permittee shall obtain from the topping plant the results of a monthly fuel sulfur analysis.

4.1 The permittee shall include in the repor t required by condition <insert cross reference to standard permit condition VII - operating reports> a list of the sulfur content measured for each month covered by the report.

4.2 The permittee shall report under condition <ins ert cross reference to standard permit

condition III - excess emissions and permit deviation reports > if the sulfur content for any month exceeds 0.75%.

The following applies to this standard permit condition:

The department will include c ondition XI.4 only in the permit fo r a North Slope facility that receives fuel from one of the North Slope topping plants.
