      (a) August 17, 1971, for affected facilities with a capacity of more than 250 million BTU per hour heat input;

      (b) April 9, 1972, for affected facilities with a capacity of 250 million BTU per hour heat input or less.

 

      Section 3. Method for Determining Allowable Emission Rates. (1) Except as provided in subsection (3) of this section, the total rated heat input capacity of all affected facilities, commenced before the applicable classification date within a source shall be used as specified in Sections 4 and 5 of this administrative regulation to determine the allowable emission in terms of pounds of effluent per million BTU heat input.

      (2) At such time as any affected facility is assigned an allowable emission rate by the cabinet, at no time thereafter shall that rate be changed due to inclusion or shutdown of any affected facility at the source.

      (3)(a) A source may petition the cabinet to establish an allowable emission rate which may be apportioned without regard to individual affected facility heat input provided that the conditions specified in paragraphs (b), (c), (d), and (e) of this subsection are met. Such allowable emission rate shall be determined according to the following equation:

F = (AB + DE)/C

Where:

      A = the allowable emission rate (in pounds per million BTU input), as determined according to 401 KAR 59:015, Section 3(1);

      B = the total rated heat input (in millions of BTU per hour) of all affected facilities commenced on or after the applicable classification date within a source, including those for which an application to construct, modify, or reconstruct has been submitted to the cabinet;

      C = the total rated heat input (in millions of BTU per hour) of all affected facilities within a source, including those for which an application to construct, modify, or reconstruct has been submitted to the cabinet;

      D = the total emission rate (in pounds per million BTU input) as determined according to subsection (1) of this section;

      E = the total rated heat input (in millions of BTU per hour) of all affected facilities commenced before the applicable classification date;

      F = the alternate allowable emission rate (in pounds per actual million BTU input).

      (b) At no time shall the owner or operator of the source allow the total emissions (in pounds per hour) from all affected facilities within the source divided by the total actual heat input (in millions of BTU per hour) of all affected facilities within the source to exceed the alternate allowable emission rate as determined by paragraph (a) of this subsection.

      (c) At no time shall the owner or operator of any source subject to federal new source performance standards allow the emissions from any affected facility commenced on or after the applicable classification date to exceed the allowable emission rate determined by use of that affected facility's rated heat input (instead of the heat input as determined by subsection (1) of this section) as specified in 401 KAR 59:015, Sections 4 and 5.

      (d) The owner or operator of the source must demonstrate compliance with this subsection by conducting a performance test according to 401 KAR 50:045 on each affected facility under such conditions as may be specified by the cabinet.

      (e) Upon petition, the cabinet will establish an alternate emission rate in accordance with this subsection if the owner or operator demonstrates to the cabinet's satisfaction that the source will maintain compliance with this subsection on a continual basis.

      Section 6. Monitoring of Operations. (1) The sulfur content of solid fuels, as burned, shall be determined in accordance with the methods specified by the cabinet.

      (2) The sulfur content of liquid fuels, as burned, shall be determined in accordance with the methods specified by the cabinet.

      (3) The rate of fuel burned for each fuel shall be measured daily or at shorter intervals and recorded. The heating value and ash content of fuels shall be ascertained at least once per week and recorded. Where the indirect heat exchanger is used to generate electricity, the average electrical output and the minimum and maximum hourly generation rate shall be measured and recorded daily.

      (4) The owner or operator of any indirect heat exchanger of more than 250 million BTU per hour heat input subject to the provisions of this administrative regulation shall maintain a file of all measurements required by this administrative regulation and summarized monthly.

      (6) For an indirect heat exchanger that does not use a flue gas desulfurization device, a continuous monitoring system as specified in 401 KAR 61:005 for measuring sulfur dioxide emissions is not required if the owner or operator monitors such emissions by fuel sampling and analysis pursuant to Section 7(6) of 401 KAR 59:015.

 

      Section 7. Test Methods and Procedures. (1) Except as provided in 401 KAR 50:045, performance tests used to demonstrate compliance with Sections 4 and 5 of this administrative regulation shall be conducted according to the following methods (filed by reference in 401 KAR 50:015):

      (a) Reference Method 1 for the selection of sampling site and sample traverses;

      (b) Reference Method 3 for gas analysis to be used when applying Reference Methods 5, 6 and 7;

      (c) Reference Method 5 for the concentration of particulate matter and the associated moisture content;

      (d) Reference Method 6 for the concentration of sulfur dioxide; and

      (e) Reference Method 7 for the concentration of nitrogen oxides.

      (2) For Reference Method 5, Reference Method 1 shall be used to select the sampling site and the number of traverse sampling points. The sampling time for each run shall be at least sixty (60) minutes and the minimum sampling volume shall be 0.85 dscm (thirty (30) dscf) except that smaller sampling times or volumes, when necessitated by process variables or other factors, may be approved by the cabinet. The probe and filter holder heating systems in the sampling train shall be set to provide a gas temperature no greater than 160°C (320°F).

      (3) For Reference Methods 6 and 7, the sampling site shall be the same as that selected for Reference Method 5. The sampling point in the duct shall be at the centroid of the cross section or at a point no closer to the walls than one (1) m (3.28 ft.). For Reference Method 6, the sample shall be extracted at a rate proportional to the gas velocity at the sampling point.

      (4) For Reference Method 6, the minimum sampling time shall be twenty (20) minutes and the minimum sampling volume shall be 0.02 dscm (0.71 dscf) for each sample. The arithmetic mean of two (2) samples shall constitute one (1) run. Samples shall be taken at approximately thirty (30) minute intervals.

      (5) For Reference Method 7, each run shall consist of at least four (4) grab samples taken at approximately fifteen (15) minute intervals. The arithmetic mean of the samples shall constitute the run value.

      (6) For each run using the methods specified by subsection (1)(c), (d), and (e) of this section, the emissions expressed in g/million cal (lb/million BTU) shall be determined by the following equation:

Where:

      E = pollutant emission, g/million cal (lb/million BTU).

      C = pollutant concentration, g/dscm (lb/dscf) determined by Reference Method 5, 6 or 7.

      F = a factor as determined in 401 KAR 59:015, Section 7.

      %O₂ = oxygen content by volume (expressed as percent), dry basis.

Percent oxygen shall be determined by using the integrated or grab sampling and analysis procedures for Reference Method 3 as applicable. The sample shall be obtained as follows:

      (a) For determination of sulfur dioxide and nitrogen oxides emissions, the oxygen sample shall be obtained simultaneously at the same point for Reference Method 6 and 7 determinations, respectively. For Reference Method 7, the oxygen sample shall be obtained using the grab sampling and analysis procedures for Reference Method 3.

      (b) For determination of particulate emissions, the oxygen sample shall be obtained simultaneously by traversing the duct at the same sampling location used for each run of Reference Method 5 under subsection (2) of this section. Reference Method 1 shall be used for selection of the number of traverse points except that no more than twelve (12) sample points are required.

      (7) When combinations of fossil fuels are fired, the heat input, expressed in cal/hr (BTU/hr), shall be determined during each testing period by multiplying the gross calorific value of each fuel fired by the rate of each fuel burned. Gross calorific value shall be determined in accordance with ASTM methods D2015-66(72) (solid fuels), D240-64(73) (liquid fuels), or D1826-64(70) (gaseous fuels), as applicable (ASTM designations filed by reference in 401 KAR 50:015). The rate of fuels burned during each testing period shall be determined by suitable methods and shall be confirmed by a material balance over the steam generation system.
