Subp. 4.
Calculating actual emissions.
The owner or operator of a stationary source may use a calculation worksheet provided by the commissioner for calculating actual emissions under this part, or may use the calculation methods under items A to E. The owner or operator must calculate actual emissions for each emissions unit, except that similar emissions units may be aggregated for emission calculation purposes. The owner or operator of a stationary source shall use the calculation method in item B instead of the calculation method in item A if the data described in item B are available for the stationary source. The alternative methods described in items C, D, and E may be used by the owner or operator without advance notification to the commissioner. The commissioner shall reject data submitted using the methods described in items B to E if the conditions set forth for the method are not fully met. To prevent double counting of emissions, the owners and operators must select one calculation method under this subpart for each emissions unit at the stationary source. Fugitive dust emissions must be included in the calculations under this subpart only if the stationary source is in a category listed in part 7007.0200, subpart 2, item B, subitems (1) to (27).
A.
All calculations of actual emissions required under this part shall be based on the stationary source's operating parameters, and must use the following equation:
E = OP x UEF x [1-CE], where
E = Actual Emissions in tons per year
OP = Operating Parameter as required by the Uncontrolled Emission Factor (hours of operation or units produced)
UEF = Uncontrolled Emission Factor (pounds of pollutant per hour of operation or units produced) as defined in part 7005.0100, subpart 10a, for uncontrolled emissions
CE = Control Efficiency (percent expressed as a decimal fraction of 1.00) determined according to part 7011.0070 for listed control equipment.
B.
If the owner or operator of the stationary source has collected emissions data through use of a continuous emission monitor (CEM) in compliance with the preconditions in subitems (1) and (2), the owner or operator shall use the CEM data to calculate actual emissions, the calculation shall be based on all of the CEM data, and the following requirements shall be met:
(2)
the CEM data have not been rejected by the commissioner due to failure by the owner or operator to comply with all requirements of parts 7017.1002 to 7017.1220; all applicable permit conditions; and any other applicable state or federal laws pertaining to CEM operation;
(3)
the total operating time of the applicable emissions unit and the total operating time of the CEM for the previous 12 consecutive months must be included in the permit application and in the monthly records required in subpart 3; and
(4)
an explanation of how the emissions were calculated based on the CEM data must be included in the permit application and in the monthly records required in subpart 3. In calculating actual emissions, the owner or operator must use the rated capacity of the flow unless the CEM provides actual data on the flow rate. For periods when the CEM is down and the emission unit is operating, the CEM data shall be substituted with emission data calculated using data obtained from the CEM. The CEM must have recorded data for at least 90 percent of the hours the emission unit was operated for the calendar year. The substitute CEM data must be representative of emission unit operation and, if applicable, of the control equipment operation during the period of CEM downtime. If substitute CEM data meeting these conditions is not available, emissions during periods of CEM downtime shall be calculated using emission factors as specified in item A or performance test data as specified in item C.
C.
Emission factors from performance tests may be used for the calculation of actual emissions, provided that:
(1)
the emissions unit is either an uncontrolled unit (for the tested pollutant) or is fitted with air pollution control equipment subject to the monitoring and record-keeping requirements of parts 7011.0060 to 7011.0080 or is fitted with air pollution equipment that has met the requirements of subpart 6; and
(2)
the performance tests met all the requirements of parts 7017.2001 to 7017.2060, and all other applicable state rules and federal regulations governing performance tests. The owner or operator of a stationary source that uses an emission factor developed from a performance test shall use the calculation method under item A.
D.
A material balance method may be used to calculate greenhouse gases as CO2e and VOC actual emissions. The owner or operator of a stationary source that uses material balance to calculate greenhouse gases as CO2e and VOC actual emissions shall determine total greenhouse gases as CO2e and VOC actual emissions (E) using the equation in this item. A separate calculation must be made for each individual gas comprising the pollutant greenhouse gases and the results converted to CO2e. The amount of CO2e from each individual gas comprising the pollutant greenhouse gases must be added together for the total tons per year of CO2e.
E = (a - b - c) x (1 - d), where
a = the amount of VOC or each individual gas comprising the pollutant greenhouse gases entering the process or the amount of carbon dioxide, nitrous oxide, or methane generated. A signed statement from the supplier or the material safety data sheet must be submitted stating the maximum amount of VOC or each individual gas comprising the pollutant greenhouse gases in any material that was used in the process.
b = the amount of VOC or each individual gas comprising the pollutant greenhouse gases incorporated permanently into the product. This includes VOCs or each individual gas comprising the pollutant greenhouse gases chemically transformed in production. It does not include latent VOC or each individual gas comprising the pollutant greenhouse gases remaining in the product that will at some time be released to the atmosphere. An explanation of this calculation must also be submitted.
c = the amount of VOC or each individual gas comprising the pollutant greenhouse gases, if any, leaving the process as waste, or otherwise not incorporated into the product and not emitted to the air.
d = the control efficiency (percent expressed as a decimal fraction of 1.00) determined according to part 7011.0070.
E.
The owner or operator of a stationary source may determine sulfur dioxide actual emissions by measuring the sulfur content of the fuel and assuming that all of the sulfur in the fuel is oxidized to sulfur dioxide. The sulfur content of each batch of fuel received must be measured by an independent laboratory using ASTM methods or verified by vendor certification. The sulfur dioxide actual emissions shall be determined for each batch of fuel received by using the following equation:
SO2 = %S/100 x F/2,000 x 2, where
SO2 = Sulfur dioxide emissions from a batch of fuel in tons.
%S = Weight percent sulfur in the fuel being burned.
F = Amount of fuel burned by weight in pounds.
2,000 = Pounds per ton.
2 or 64/32 = Pounds of sulfur dioxide per pound of sulfur in one pound-mole.
The total sulfur dioxide emissions for the year shall be the sum total of the individual batch totals.
Subp. 5.
Emissions thresholds.
The owner or operator must calculate actual emissions for the stationary source using the calculations under subpart 4 and the calculated 12-month rolling sum of actual emissions must be less than or equal to the thresholds listed in Table 3.
TABLE 3
OPTION D EMISSIONS THRESHOLDS
| POLLUTANT | THRESHOLD (ton/year) |
| HAP | 5 tons/year for a single HAP |

A.
operate the control equipment whenever operating the emission units controlled by the control equipment in compliance with this item. The control equipment shall at all times be operated in the range established by the control equipment manufacturer's specifications for each control equipment parameter that is required to be monitored by the approved test plan during the performance test, or within the operating parameters set by the commissioner as the result of the most recent performance test conducted under parts 7017.2001 to 7017.2060, if those are more restrictive. The control equipment must have been manufactured by a control equipment manufacturer as defined in part 7011.0060, subpart 3. The monitoring parameters shall indicate that the control equipment is operating under the same conditions as during the performance test. If the commissioner determines such monitoring parameters do not exist, then an emission factor may not be established through a performance test under this part;
C.
operate the monitoring equipment for each parameter required to be monitored as part of the approved test at all times the control equipment is required to operate;
D.
record each parameter required to be monitored at least every 24 hours when in operation or more frequently, if the commissioner determines that more frequent monitoring is required to determine the control equipment is operating under the same conditions as during the performance test;
E.
report to the commissioner any recorded reading outside the specification or range of specification of any monitored parameter required by the approved test plan in accordance with the deadlines in part 7007.0800, subpart 6, item A, subitem (2), except that owners or operators shall make this report only if a deviation occurred in the reporting period;
F.
conduct additional performance tests, upon request of the commissioner or the administrator, to verify the accuracy of the emission factor or for any of the reasons specified in part 7017.2020, subpart 1;
G.
in the event of a shutdown or breakdown of control or process equipment or deviations which would endanger human health or the environment, comply with part 7019.1000;
H.
recalculate the actual emissions if the owner or operator becomes aware of information indicating that the emission factor determined through the performance test is no longer representative; and
I.
if the emissions are discharged to the control equipment through a hood, maintain at the stationary source the evaluation of each hood, and record each month the fan rotation speed, fan power draw, or face velocity of each hood, or other comparable air flow indication method.
