PURPOSE: The purpose of this proposed amendment is to update incorporation by reference information, make typographical corrections, and remove the unnecessary use of restrictive words. The evidence supporting the need for this proposed amendment, per 536.016, RSMo, is Executive Order 17-03 Red Tape Reduction Review and related comments.

PURPOSE: This rule restricts the emission of particulate matter from fuel burning equipment used for indirect heating except where 10 CSR 10-6.070 would be applied. The evidence supporting the need for this proposed rulemaking, per section 536.016, RSMo, is a necessity evidence memorandum dated March 5, 2008.

PUBLISHER'S NOTE: The secretary of state has determined that the publication of the entire text of the material which is incorporated by reference as a portion of this rule would be unduly cumbersome or expensive. This material as incorporated by reference in this rule shall be maintained by the agency at its headquarters and shall be made available to the public for inspection and copying at no more than the actual cost of reproduction. This note applies only to the reference material. The entire text of the rule is printed here.

(1) Applicability.
(A) This rule applies throughout the state with additional conditions applicable to the metropolitan areas of Kansas City, Springfield, and St. Louis as found in sections (2) and (3) of this rule.
(B) This rule applies to installations in which fuel is burned for the primary purpose of producing steam, hot water, or hot air or other indirect heating of liquids, gases, or solids and, in the course of doing so, the products of combustion do not come into direct contact with process materials. Fuels may include, but are not limited to, coal, tire derived fuel, coke, lignite, coke breeze, gas, fuel oil, bio-mass, and wood, but do not include refuse. When any products or byproducts of a manufacturing process are burned for the same purpose or in conjunction with any fuel, the same maximum emission rate limitations apply.
(C) An emission unit that is subject to 10 CSR 10-6.070 and in compliance with applicable provisions; or an emission unit fueled by landfill gas, propane, natural gas, fuel oils #2 through #6 (with less than one and two-tenths percent (1.2%) sulfur), and/or other gases (with hydrogen sulfide levels less than or equal to four (4) parts per million volume as measured using ASTM D4084, as specified in 10 CSR 10-6.040(23), or equivalent and mercury concentrations less than forty (40) micrograms per cubic meter as measured using ASTM D5954, as specified in 10 CSR 10-6.040(30), or ASTM D6350, as specified in 10 CSR 10-6.040(32), or equivalent) would be deemed in compliance with 10 CSR 10-6.405.
(D) The heat input from emission units in subsection (1)(C) of this rule must be included in the calculation of Q, the installation's total heat input as defined in subsections (3)(D) and (3)(E) of this rule.
(E) An installation is exempt from this rule if all of the installation's applicable units are fueled only by landfill gas, propane, natural gas, fuel oils #2 through #6 (with less than one and two-tenths percent (1.2%) sulfur), or other gases (with hydrogen sulfide levels less than or equal to four (4) parts per million volume as measured using ASTM D4084, as specified in 10 CSR 10-6.040(23), or equivalent and mercury concentrations less than forty (40) micro-grams per cubic meter as measured using ASTM D5954, as specified in 10 CSR 10-6.040(30), or ASTM D6350, as specified in 10 CSR 10-6.040(32), or equivalent) or any combination of these fuels.
(2) Definitions.
(A) Existing Any source which was in being, installed, or under construction on the date provided in the following table:

Area of State

Construction date began on or before

Kansas City Metropolitan Area

February 15, 1979*

St. Louis Metropolitan Area

February 15, 1979*

Springfield-Greene County Area

September 24, 1971

Outstate Area

February 24, 1971

*Exception: If any source subsequently is altered, repaired, or rebuilt at a cost of thirty percent (30%) or more of its replacement cost, exclusive of routine maintenance, it no longer is considered an exist-ing source but will be considered a new source.

(B) New-Any source which is not an existing source, as defined in subsection (2)(A) of this rule.
(C) Definitions of certain terms specified in this rule, other than those defined in this rule section, may be found in 10 CSR 10-6.020.
(3) General Provisions.
(A) The heat content of solid fuels shall be determined as specified in 10 CSR 10-6.040(2). The heat content of liquid hydro-carbon fuels shall be determined as specified in 10 CSR 10-6.040(3).
(B) For purposes of this rule, the heat input is the aggregate heat content of all fuels whose products of combustion pass through a stack(s). The hourly heat input value used shall be the equipment manufacturer's or designer's guaranteed maximum input, whichever is greater, except in the case of boilers of ten (10) million British thermal units (mmBtu) or less the heat input can also be determined by the higher heating value (HHV) of the fuel used at maximum operating conditions. The total heat input of all fuel burning units used for indirect heating at a plant or on a premises is used for determining the maximum allowable amount of particulate matter which may be emitted.
(C) Indirect heating sources requiring permits under 10 CSR 10-6.060 that in turn may require particular air pollution control measures to meet more stringent emission rate limitations than in this rule shall meet the requirements of the permits issued under 10 CSR 10-6.060 Construction Permits Required.
(D) Emission Rate Limitations for Existing Indirect Heating Sources. No person may cause, allow, or permit the emission of particulate matter from existing indirect heating sources in excess of that specified in the following table:

Q = the summation of heat input in mmBtu/hour from all affected fuel burning equipment at a source (including existing equipment, new equipment, NSPS units, and other clean units identified in subsection (1) (C) of this rule).

(F) Alternate Method of Compliance.
1. Compliance with this rule also may be demonstrated if the weighted average emission rate (WAER) of two (2) or more indirect heating sources is less than or equal to the maximum allowable particulate E determined in subsection (3)(D) or (3)(E) of this rule. The WAER for the indirect heating sources to be averaged is calculated by the following formula:

Where:

WAER = the weighted average emission rate in pounds per mmBtu;

Eai = the actual emission rate of the ith indirect heating source in pounds per mmBtu;

Qi = the rated heat input of the ith indirect heating source in mmBtu per hour; and

n = the number of indirect heating sources in the average.

2. Installations demonstrating compliance with this rule in accordance with the requirements of subsection (3)(F) of this rule do so by making written application to the director. The application shall include the calculations performed in paragraph (3)(F)1. of this rule and all necessary information relative to making this demonstration.
3. Subsection (3)(F) of this rule only applies if the WAER determined by paragraph (3)(F)2. of this rule for indirect heating sources does not exceed the maximum allowable particulate E determined for that source from subsection (3)(D) or (3)(E) of this rule when using the rated heat input, Qi, for the individual indirect heating source as if that individual indirect heating source was the only such source at the installation.
(4) Reporting and Record Keeping. All records must be kept on-site for a period of five (5) years and made available to the department upon request. The owner or operator shall maintain records of the following information for each year the unit is operated:
(A) The identification of each affected unit and the name and address of the plant where the unit is located for each unit subject to this rule;
(B) The calendar date of the record;
(C) The emission rate in pounds per mmBtu for each unit on an annual basis for those units complying with the limit in subsections (3)(D) and (3)(E) of this rule; and
(D) The emission rate in pounds per mmBtu for each facility on an annual basis for those units complying with subsection (3)(F) of this rule.
(5) Test Methods. The following hierarchy of methods shall be used to determine compliance with subsections (3)(D) and (3)(E) of this rule:
(A) Continuous Emission Monitoring System (CEMS);
(B) Stack tests, as specified in 10 CSR 10-6.030(5)(A) or (5)(B);
(C) Other EPA documents;
(D) Compliance Assurance Monitoring (CAM) Plans as found in a facility operating permit may be used to provide a reasonable assurance of compliance with subsections (3)(D) and (3)(E) of this rule;
(E) Sound engineering calculations;
(F) Any other method, such as AP-42 (U.S. Environmental Protection Agency (EPA) Compilation of Air Pollutant Emission Factors) or Factor Information and Retrieval System (FIRE), approved for the source by incorporation into a construction or operating permit, settlement agreement, or other federally enforceable document. AP-42 (Environmental Protection Agency (EPA) Compilation of Air Pollutant Emission Factors) and Factor Information and Retrieval System (FIRE) as published by E PA January 1995 and August 1995 are hereby incorporated by reference in this rule. Copies can be obtained from the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. This rule does not incorporate any subsequent amendments or additions; or
(G) Other alternate emission estimation methods not listed in this section when pre-approval is obtained from the department and EPA before using such methods to estimate emissions.
