§
### A.

§
### G.

the owner or operator does not anticipate making changes in the next 12 months which will cause the stationary source to be ineligible for this type of registration permit under items A to F and H; and

§
### H.

the stationary source does not use or generate nitrous oxide, other than from combustion units, and does not use or generate hydrofluorocarbons, perfluorocarbons, or sulfur hexafluoride.

§
## Subp. 4.

## Tables and calculations.

The tables and calculations in this subpart shall be used to determine whether a stationary source is eligible for a registration permit under this part. For the purposes for fuel specifications listed in calculations 1 and 2A, the Annual Book of American Society for Testing and Materials Standards (ASTM), 100 Barr Harbor Drive, West Conshocken, PA 19428-2959, volumes 4.05, 5.01, 5.03, and 5.05 (1993) are incorporated by reference. ASTM is the author and publisher. These publications are available through the Minitex interlibrary loan system (University of Minnesota Library). These documents are subject to frequent change.

**Calculation 1. Indirect Heating Emissions Units.** For stationary sources with indirect heating emissions units, multiply the 12-month rolling sum of each fuel used by the multiplication factor (MF) listed in Table 1. Add the results of all the calculations to arrive at the calculation 1 total. The following formula determines the calculation 1 total:

STEP 1: fuel type used (in units specified) x MF = fuel type total

STEP 2: fuel type 1 total + fuel type 2 total + ... fuel type *n* total = Calculation 1 total

TABLE 1 | ||

FUEL USED (units burned/year)-[specification] | SULFUR LIMIT | MULTIPLI- CATION FACTOR (MF) |

anthracite coal (tons)-[ASTM D 388(Vol 05.05)] | 2.38% | 4.64E-02 |

bituminous coal (tons)-[ASTM D 388(Vol 05.05)] | 2.10% | 4.10E-02 |

sub bituminous coal (tons)-[ASTM D 388 (Vol 05.05)] | 1.66% | 2.91E-02 |

lignite A coal (tons)-[ASTM D 388(Vol 05.05)] | 1.26% | 1.89E-02 |

No. 4 distillate (gallons)-[ASTM D 396(Vol 05.01)] | 1.80% | 1.40E-04 |

No. 5 and No. 6 residual (gallons)-[ASTM D 396(Vol 05.01)] | 1.80% | 1.46E-04 |

liquefied petroleum gas (LPG) (gallons)-[ASTM D 1835(Vol 05.01 and 05.05)] | n/a | 1.05E-05 |

dry or commercial pipeline natural gas (cubic feet)-this must be a mixture of ethane, methane, not more than five percent propane and not more than one percent butane | n/a | 1.40E-07 |

**Calculation 2. Reciprocating Internal Combustion Engine Emission Units.** A stationary source with one or more reciprocating internal combustion (RIC) engines shall, for each RIC engine, use either calculation 2A or 2B. Stationary sources with RIC engine emission units burning fuels not listed in Table 2, however, must use calculation 2B.

**Calculation 2A. RIC Engine Fuel Usage Calculation.** For stationary sources with one or more RIC engines, multiply the 12-month rolling sum of each fuel used by the multiplication factor (MF) from Table 2. Add the results of each calculation to determine the total for that RIC engine. The following formula determines the calculation 2A total:

STEP 1: fuel type used (in specified units) x MF = fuel type total

STEP 2: fuel type 1 total + fuel type 2 total + ... fuel type *n* total = Calculation 2A total

TABLE 2 | ||

FUEL USED (units burned/year)-[specification] | SULFUR LIMIT | MULTIPLI- CATION FACTOR (MF) |

No. 1 and No. 2 diesel, and kerosene (gallons)-[ASTM 975(Vol 05.01)] | 0.5% | 3.09E-04 |

liquefied petroleum gas (LPG) (gallons)-[ASTM D 1835(Vol 05.01 and 05.05)] | n/a | 6.95E-05 |

dry or commercial pipeline natural gas (cubic feet)-[as defined in Table 1] | n/a | 1.70E-06 |

**Calculation 2B. RIC Engine Operating Hours Calculation.** For stationary sources with one or more RIC engines, multiply the design capacity of the engine in horsepower by the 12-month rolling sum of hours operated and by the multiplication factor 1.22E-05. The owner or operator shall perform this calculation for each RIC engine, then add the results of all the calculations to arrive at the calculation 2B total. The following formula determines the calculation 2B total:

STEP 1: engine horsepower design capacity x hours operated x 1.22E-05 = RIC engine total

STEP 2: RIC engine 1 total + RIC engine 2 total + ... RIC engine *n* total = Calculation 2B total

**Calculation 3. VOC Emissions Units.** An owner or operator of a stationary source which purchases or uses VOC-containing materials shall, for each material purchased or used which contains VOC, multiply a factor of ten by the weight factor (WF) of the VOC in the material (weight of VOC per weight of VOC-containing material) by the density of the material (in pounds per gallon) by the 12-month rolling sum of gallons of that material purchased or used. The owner or operator shall perform this calculation for each material purchased or used which contains VOC (including VOC purchased or used for cleaning) and add the results of the calculations to arrive at the calculation 3 total. In determining the WF and the density, the owner or operator shall use the maximum listed in the material safety data sheets (MSDS) or a signed statement from the supplier for each VOC-containing material. The following formula determines the calculation 3 total:

STEP 1: 10 [WF x density of the material (lb/gal) x (1 ton/2,000 lb) x the 12-month rolling sum of material purchased or used (gallons)] = material total

STEP 2: material 1 + material 2 + ... material *n* total = Calculation 3 total

§
## Subp. 5.

## Transition period.

Any owner or operator of a stationary source that holds a registration permit option C and is ineligible for a registration permit option C on or after January 1, 2007, shall apply for another type of permit on or before December 31, 2008.
