Sec. 1.
Test methods for 326 IAC 6.8-2, 326 IAC 6.8-4, 326 IAC 6.8-5, and 326 IAC 6.8-8 shall be as follows:
(1) Emissions of PM10 shall be measured by any of the following: (A) 40 CFR 51, Appendix M, Method 201*.(B) 40 CFR 51, Appendix M, Method 201A*.(C) The volumetric flow rate and gas velocity shall be determined in accordance with 40 CFR 60, Appendix A, Method 1, 1A, 2, 2A, 2C, 2D, 3, or 4*.(2) Emissions for TSP and particulate matter shall be measured by the following methods: (A) 40 CFR 60, Appendix A, Methods 5, 5A, 5D, 5E, or 17*. Method 17 may not be used when the stack gas temperature exceeds two hundred forty-eight (248) degrees Fahrenheit. (±25°F).(B) The volumetric flow rate and gas velocity shall be determined in accordance with 40 CFR 60, Appendix A, Methods 1, 1A, 2, 2A, 2C, 2D, 3, or 4*.(3) Measurements of opacity shall be conducted in accordance with the following: (A) 40 CFR 60, Appendix A, Method 9*, except for those sources where a three (3) minute averaging time is required.(B) Sources requiring a three (3) minute averaging time are subject to all parts of Method 9* except the six (6) minute averaging provision. In these cases, the opacity shall be determined as an average of twelve (12) consecutive observations recorded at fifteen (15) second intervals.(4) Emissions of sulfuric acid mist shall be measured in accordance with 40 CFR 60, Appendix A, Method 8*.(5) Compliance with the mass emission limits for the sinter plant windbox stacks at U.S. Steel-Gary Works in 326 IAC 6.8-2 shall be determined by the following:(A) The simultaneous sampling and analysis of both noncondensibles (front half) and condensibles (back half) particulate matter.(B) The quantity of noncondensibles particulate matter in the gas stream shall be determined in accordance with the procedures specified in 40 CFR 60, Appendix A, Method 5*.(C) The quantity of condensible particulate matter in the gas stream shall be determined in accordance with 40 CFR 51, Appendix M, Method 202*, with the following modifications: (i) A heated Method 5 out of stack filter shall be used instead of an in-stack filter. (ii) The impinger system shall consist of five (5) impingers. The:(AA) first three (3) impingers shall contain one hundred (100) milliliters of deionized water;(BB) fourth shall be empty; and(CC) fifth shall contain silica gel.(iii) The first four (4) impingers shall be used to determine the quantity of condensible particulate emissions.(D) Compliance shall be achieved if the: (i) sum of the front half and the back half is less than or equal to the mass emission limit of one hundred (100) lbs/hr per stack; and(ii) front half catch is less than or equal to the mass concentration limit of twenty-thousandths (0.020) gr/dscf in 326 IAC 6.8-2. *These documents are incorporated by reference and are available from the Government Printing Office, 732 North Capitol Avenue NW, Washington, D.C. 20401 or are available for review and copying at the Indiana Department of Environmental Management, Office of Air Quality, Indiana Government Center-North, Tenth Floor, 100 North Senate Avenue, Indianapolis, Indiana 46204.
