Current through Register Vol. 49, No.12, June 17, 2024

Section 10 CSR 10-6.400 - Restriction of Emission of Particulate Matter From Industrial Processes

PURPOSE: This regulation restricts the emission of filterable particulate matter in the source gas of an operation or activity except where 10 CSR 10-6.405 and/or 10 CSR 10-6.070 would be applied.

(1) Applicability.

(A) This regulation applies to any operation, process, or activity that emits particulate matter.

(B) The provisions of this rule shall not apply to the following:

1. Cotton gins;

2. The grinding, crushing, and classifying operations at a rock quarry;

3. The receiving and shipping of whole grain from or into a railroad or truck transportation source at a grain elevator;

4. Smoke generating devices, as defined in subsection (2)(D) of this rule, when a required permit or a written determination that a permit is not required has been issued or written;

5. Batch-type charcoal kilns required to comply with 10 CSR 10-6.330;

6. The burning of fuel for indirect heating;

7. Fugitive emissions;

8. Emission sources that are exempt from construction permitting under 10 CSR 10-6.061;

9. Emission sources that are permitted by rule under 10 CSR 10-6.062;

10. The burning of refuse;

11. The processing of salvageable material by burning;

12. Emission units that at maximum design capacity have a potential to emit less than one-half (0.5) pounds per hour of particulate matter;

13. The grinding, crushing, and conveying operations at a power plant;

14. Coating operations equipped with a control system designed to control at least ninety-five percent (95%) of the particulate overspray provided the system is operated and maintained in accordance with manufacturers' specifications or comparable maintenance procedures that meet or exceed manufacturers' specifications;

15. Any particulate matter emission unit that is subject to a federally enforceable requirement to install, operate, and maintain a particulate matter control device system that controls at least ninety percent (90%) of particulate matter emissions; and

16. Emission units that at maximum hourly design rate (MHDR) have an uncontrolled potential to emit less than the allowable emissions as calculated in paragraphs (3)(A)1. and (3)(A)2. of this rule.

(C) In the event that other rules in Title 10 Code of State Regulations are also applicable to particulate matter emission units, the more stringent requirement shall apply.

(2) Definitions. Definitions of certain terms specified in this rule may be found in 10 CSR 10-6.020.

(3) General Provisions.

(A) Emission Limitations. All applicable sources, except grey iron jobbing cupolas and corn wet milling drying processes, shall meet the following requirements:

1. Except as provided for in paragraph (3)(A)2. and subsection (1)(B) of this rule, no person shall cause, suffer, allow or permit the emission of particulate matter in any one (1) hour from any source in excess of the amount calculated using one of the following equations selected based on the applicable process weight rate:

For process weight rates of 60,000 pounds per hour (lb/hr) or less:

E = 4.10P ^0.67

and for process weight rates greater than 60,000 lb/hr:

E = 55.0P ^0.11 - 40;

where:

E = rate of emission in lb/hr; and

P = process weight rate in tons per hour

(tons/hr); or

2. The limitations established by paragraph (3)(A)1. of this rule shall not require the reduction of particulate matter concentration, based on the source gas volume, below the concentration specified in paragraph (3)(A)2., Table I of this rule for that volume; provided that, for the purposes of this section, the person responsible for the emission may elect to substitute a volume determined according to the provisions of paragraph (3)(A)3. of this rule; and provided further that the burden of showing the source gas volume or other volume substituted, including all the factors which determine volume and the methods of determining and computing the volume shall be on the person seeking to comply with the provisions of this section.

3. Any volume of gases passing through and leaving an air pollution abatement operation may be substituted for the source gas volume of the emission unit served by the air pollution abatement operation, for the purposes of paragraph (3)(A)2. of this rule, provided that air pollution abatement operation emits no more than forty percent (40%) of the weight of particulate matter entering; and provided further that the substituted volume shall be corrected to standard conditions and to a moisture content no greater than that of any gas stream entering the air pollution abatement operation and further provided that there is an enforceable requirement to operate the air pollution abatement equipment; and

4. Notwithstanding the provisions of paragraphs (3)(A)1. and (3)(A)2. of this rule, no person shall cause, allow, or permit the emission of particulate matter from any source in a concentration in excess of 0.30 grain per standard cubic foot of exhaust gases.

(B) Grey iron jobbing cupolas shall meet the following requirements:

1. Cupolas shall be equipped with gas cleaning devices operated to remove not less than eighty-five percent (85%) by weight of all the particulate matter in the cupola discharge gases or release not more than 0.4 grain of particulate matter per standard cubic foot of discharge gas, whichever is more stringent; and

2. All gases, vapors, and gas entrained effluents shall be incinerated at a temperature not less than one thousand two hundred degrees Fahrenheit (1,200 °F) for a period of not less than 0.3 seconds.

(C) All existing corn wet milling drying processes shall be equipped with gas cleaning devices operated to remove not less than ninety-nine and one-half percent (99.5%) by weight of all particulate matter in the dryer discharge gases or release not more than one one-hundredth grain of particulate matter per dry standard cubic foot (0.01 gr/dscf) of discharge gas.

(4) Reporting and Record Keeping. All records of any tests performed to determine the amount of particulate matter emitted from a unit shall be kept on-site and available for inspection for five (5) years following the test date.

(5) Test Methods. The following hierarchy of emission measurement approaches shall be used to determine compliance with section (3) of this rule. If compliance data is not available from a measurement approach, or an approach is impractical for a source, then the next approach listed in the hierarchy shall be used in its place. The choice of an emissions measurement approach is subject to the approval of the director-

(A) Continuous Emission Monitoring System (CEMS);

(B) Stack tests as specified in 10 CSR 10-6.030(5)(A) or (5)(B), as determined by the director;

(C) Compliance Assurance Monitoring (CAM) plan found in the facility's operating permit; or

(D) Other methods, as described in permits issued under 10 CSR 10-6.060 or 10 CSR 10-6.065 or as approved by the director. These may include approved engineering calculations or other U.S. Environmental Protection Agency documentation.
