Current through Register Vol. XLI, No. 50, December 13, 2024

Section 45-7A-3 - Mass Emission Test Procedures

3.1. Compliance with the mass emission standards set forth in sections 3 and 4 of 45CSR7 shall be determined in accordance with the following:

3.1.a. Except as otherwise provided in section 3.1., stack testing to determine particulate mass emissions shall be performed using the methodology set forth in 40 CFR, Part 60, Appendix A, Methods 1 through 5, as published July 1, 1997, unless the Director determines that some aspect of the methods are not appropriate or adaptable to a particular manufacturing process source operation due to process parameters, access to test location, or other factors.

In the event that Methods 1-5 cannot be employed for a particular process operation, the Director may specify or approve alternative methods or variances to these reference methods that have been demonstrated to be equivalent. Such alternative methods may include the methodology set forth in 40 CFR, Part 60, Appendix A, Method 17, as published July 1, 1997.

3.1.a.1. Compliance shall be determined by taking the average of the mass emission rates determined from three (3) consecutive test runs conducted during a seven (7) day period.

3.1.a.2. Unless otherwise approved or specified by the Director, a minimum volume of thirty (30) standard cubic feet (SCF) of gas must be sampled per test run.

3.1.b. Unless otherwise approved or specified by the Director, all mass emission compliance tests shall be conducted during periods of maximum production rates and under conditions which are otherwise representative of normal operation. Maximum production rates shall be the maximum design capacity of the emitting source or unit, unless the Director has determined that the equipment can be and is routinely operated at production rates above the design rate or it is demonstrated to the satisfaction of the Director that the equipment cannot be operated at design capacity.

3.1.c. At least thirty (30) days prior to each compliance test, a test protocol must be furnished to the Director for his review and approval and providing as a minimum, the following information:

3.1.c.1. Identification and description of the process operation that is to be tested;

3.1.c.2. A discussion of the manner in which the process operation will be operated during the test periods with respect to production or process weight rates, representativeness of feed or raw materials to be used, operating temperatures, and other factors which may affect emissions;

3.1.c.3. A description or listing of process and control equipment data that will be monitored and recorded during the tests runs;

3.1.c.4. A description of test methods and equipment that will be employed with requests for approval of any variances to the reference test methods. If sampling is to be non-continuous as a result of the cyclical nature of the process or other factors, this must be fully described;

3.1.c.5. A drawing of the stack or duct sections where samples will be taken showing distances to upstream and downstream gas flow disturbances or bends and changes in duct or stack cross sections;

3.1.c.6. A drawing of the test plane(s) showing dimensions and number and location of sampling (traverse) points;

3.1.c.7. The sampling time at each traverse point and total sampling time for each test run. If the sampling time per traverse point is to be less than two minutes, comments must be written concerning the variability of gas flow and temperatures during the short sampling time and how the sampling rate will be monitored and adjusted to maintain isokinetic conditions;

3.1.c.8. The minimum volume (SCF) of gas that will be sampled per test run; and

3.1.c.9. Name of the person to contact concerning the scheduled tests and affiliation of personnel who will actually conduct the tests.

3.1.d. Notification of the dates upon which compliance testing will be conducted must be provided to the Director, in writing, no later than fifteen (15) days prior to the date of the first test run so that he may, at his option, have an observer present during the test runs and sample analyses. Sampling data, operating parameters and other information relevant to the emissions tests, are to be made available to the Director's test observers, on request, during the test periods. Any such data or other information so made available to the Director shall also be made available to the public in accordance with W.Va. Code ''22-5-1 et seq., 29B-1-1 et seq., and 45CSR31.

3.1.g.2. A steel production cycle shall be defined as the time from the start of the hot metal charge until the end of the tap.

3.1.g.3. Calculation of the allowable emissions shall be based upon the total tons of raw steel produced during the four (4) steel production cycles that compose each run.

3.1.h. Except as provided in section 3.1.h.4., stack sampling procedures for determining compliance with applicable emission standards for facilities equipped with modular baghouses shall be as follows:

3.1.h.1. The methods described in section 3.1.a. shall be used except as provided in sections 3.1.h.2. and 3.1.h.3.

3.1.h.2. Compliance shall be determined from the results of at least one (1) test run performed on each stack or exhaust vent. For the purpose of determining compliance with a mass emission rate standard expressed in pounds per hour, the results of the tests performed on each stack or exhaust vent shall be summed. Compliance with a mass concentration standard shall be determined by using a gas flow-weighted average of the concentrations measured from all stacks or vents.

3.1.h.3. The compliance demonstration shall be based upon a minimum of three (3) test runs. If more than one test run is performed on one stack or exhaust vent the results of the test runs on that stack shall be averaged prior to summing or determining weighted averages in accordance with section 3.1.h.2.

3.1.h.4. The Director may approve compliance determinations based upon fewer test runs than required in section 3.1.h.2. if he determines that the requirements of section 3.1.h.2. place excessive demands upon the process source owner to demonstrate compliance.

3.1.i. For the purpose of determining compliance with the standards set forth in sections 4.8.b. and4.8.c.1. of 45CSR7 for fluorides, the test methods and procedures set forth in 40 CFR 60 Appendix A, Methods 1, 2, 3, 13A, 13B, and 14, as published on July 1, 1997, shall be used unless the Director determines that some aspect of those methods are not appropriate or adaptable to an affected facility. In the event that the referenced methods cannot be employed, the Director may specify or approve alternative methods or variances to the reference methods that have been demonstrated to be equivalent. The sampling time and sample volume for each test run shall be at least 8 hours and 6.80 dscm (240 dscf). Each compliance test shall be based on the arithmetic average of the results of at least three consecutive test runs.

3.1.j. Compliance with the emissions standards of section 4.2. of 45CSR7 for mineral acids shall be determined in accordance with the following unless the Director determines that alternative methods are required due to interferences or other factors:

3.1.j.1. For sulfuric acid mist: 40 CFR 60.85(a) and (b) and 40 CFR 60 Appendix A, Methods 1, 2, 3, and 8, as published on July 1, 1997, except that the SO₂ emission rate does not necessarily have to be determined. The sulfuric acid mist concentration shall be expressed in milligrams per dry standard cubic meter.

3.1.j.2. For hydrochloric acid mist and/or vapor: 40 CFR 60, Appendix A, Method 26 or, if the source exhausts through a wet scrubber, Method 26A of Appendix A, as published on July 1, 1997.

3.1.j.3. For nitric acid mist and/or vapor and phosphoric acid mist and/or vapor: methods approved by the Director. The Director shall give preference to the use of methods promulgated by the U.S. EPA for these acids if available and adaptable to a specific source.

3.1.j.4. Tests to determine compliance with mineral acid concentration limits shall be based on the arithmetic average of the results of at least three consecutive test runs.
