PURPOSE: This rule restricts the emission of particulate matter in the source gas of an operation or activity except where 10 CSR 10- 3.060 would be applied.

PUBLISHER’S NOTE: The publication of the full text of the material that the adopting agency has incorporated by reference in this rule would be unduly cumbersome or expensive. Therefore, the full text of that material will be made available to any interested person at both the Office of the Secretary of State and the office of the adopting agency, pursuant to section 536.031.4, RSMo. Such material will be provided at the cost established by state law.

1. (1) Application. This rule shall apply throughout Missouri except in the City of St. Louis and St. Charles, St. Louis, Jefferson, Franklin, Clay, Cass, Buchanan, Ray, Jackson, Platte and Greene Counties.
2. (2) Definitions of terms specified in this rule may be found in 10 CSR 10-6.020.

3. (3) General Provisions.

   1. (A) This rule applies to any operation, process or activity except the burning of fuel for indirect heating in which the products of combustion do not come into direct contact with process materials and except the burning

of refuse and except the processing of salvageable material by burning.

1. (B) Process weight means the total weight of all materials introduced into a source operation, including solid fuels, but excluding liquids and gases used solely as fuels and excluding air introduced for purposes of combustion. Process weight rate means a rate established as follows:

   1. 1. For continuous or long-run steady-

state source operations the total process weight for the entire period of continuous operation or for a typical portion, divided by the number of hours of that period or portion;

1. 2. For cyclical or batch source opera-

tions, the total process weight for a period which covers a complete operation or an integral number of cycles, divided by the hours of actual process operation during period; or

1. 3. Where the nature of any process or

operation or the design of any equipment permits more than one (1) interpretation of this section, that interpretation which results in the minimum value for allowable emission shall apply.

1. (C) The amount of particulate matter emitted shall be determined as specified in 10 CSR 10-6.030(5). Any other method which is in accordance with good professional practice may be used with the consent of the staff director.

1. (4) Emission Limitations.

   1. (A) Except as provided for in subsection (4)(B) and section (5) 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 shown in Table I for the process weight allocated to the source.

Interpolation of the data in this table for process weight rates up to 60,000 lb/hr shall be accomplished by use of the equation E=4.10P0.67 and interpolation and extrapolation of the data for process weight rates in excess of 60,000 lb/hr shall be accomplished by use of the equation—

E=55.0(P)0.11 - 40

where E = rate of emission in lb/hr; and P = process weight rate in tons/hr.

1. (B) The limitations established by subsection (4)(A) of this rule shall not require the reduction of particulate matter concentration, based on the source gas volume, below the concentration specified in Table II for that volume; provided, that, for the purposes of subsection (4)(B), the person responsible for the emission may elect to substitute a volume determined according to the provisions of subsection (4)(C) 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 the volume and the methods of determining and computing the volume, shall be on the person seeking to come within the provisions of this rule.

1. (C) Any volume of gases passing through and leaving an air pollution abatement operation may be substituted for the source gas volume of the source operation served by the air pollution abatement operation for the purposes of subsection (4)(B) of this rule; provided, the air pollution abatement operation emits no more than forty percent (40%) of the weight of particulate matter entering; and provided further that 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.
2. (D) Notwithstanding the provisions of subsections (4)(A) and (B) of this rule, no person may 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 gas.

1. (5) Exceptions.

   1. (A) The provisions of (4)(A)–(D) of this rule shall not apply to existing grey iron jobbing cupolas. For purposes of this rule, a jobbing cupola is defined as a cupola which has a single melting cycle operated no more than ten (10) hours in any consecutive twenty-four (24) hours and no more than fifty (50) hours in any consecutive seven (7) days. 0.092 0.089 0.071 0.062 0.057 0.053 0.050 0.045

1. (6) Time Schedule for Compliance. Except as otherwise specified, compliance with the provisions of this rule shall be according to the following time schedule:

   1. (A) All new installations shall comply when operation begins;
   2. (B) All existing installations not in compliance as of the effective date of this rule (April 3, 1971) shall be in compliance within six (6) months of the effective date (September 3, 1971) unless the owner or person responsible for the operation of the installation shall have submitted to the staff director in a form and manner satisfactory to him/her, a program and schedule for achieving compliance, program and schedule to contain a date on or before which full compliance will be attained and other information as the staff director may require. If approved by the staff director, that date will be the date on which the person shall comply; and
   3. (C) The staff director may require persons submitting the program to submit subsequent periodic reports on progress in achieving compliance.
