【正文】 gnite automatically, or cannot be ignited due to accessibility or safety issues. You must document and maintain records of this determination. The determination of ignitability, accessibility, and safety may enpass multiple casting patterns provided the castings utilize similar sandtometal ratios, binder formulations, and coating materials. The determination of ignitability must be based on observations of the mold vents within 5 minutes of pouring, and the flame must be present for at least 15 seconds for the mold vent to be considered ignited. For the purpose of this determination:(i) Mold vents that ignite more than 75 percent of the time without the presence of an auxiliary ignition source are considered to ignite automatically。 and(ii) Mold vents that do not ignite automatically and cannot be ignited in the presence of an auxiliary ignition source more than 25 percent of the time are considered to be not ignitable.[69 FR 21923, Apr. 22, 2004, as amended at 73 FR 7218, Feb. 7, 2008]General Compliance Requirements167。What are my general requirements for plying with this subpart?(a) You must be in pliance with the emissions limitations, work practice standards, and operation and maintenance requirements in this subpart at all times, except during periods of startup, shutdown, or malfunction.(b) During the period between the pliance date specified for your iron and steel foundry in 167。 and the date when applicable operating limits have been established during the initial performance test, you must maintain a log detailing the operation and maintenance of the process and emissions control equipment.(c) You must develop a written startup, shutdown, and malfunction plan according to the provisions in 167。(e)(3). The startup, shutdown, and malfunction plan also must specify what constitutes a shutdown of a cupola and how to determine that operating conditions are normal following startup of a cupola.[69 FR 21923, Apr. 22, 2004, as amended at 71 FR 20468, Apr. 20, 2006]Initial Compliance Requirements167。By what date must I conduct performance tests or other initial pliance demonstrations?(a) As required by 167。(a)(2), you must conduct a performance test no later than 180 calendar days after the pliance date that is specified in 167。 for your iron and steel foundry to demonstrate initial pliance with each emissions limitation in 167。 that applies to you.(b) For each work practice standard in 167。 and each operation and maintenance requirement in 167。 that applies to you where initial pliance is not demonstrated using a performance test, you must demonstrate initial pliance no later than 30 calendar days after the pliance date that is specified for your iron and steel foundry in 167。.(c) If you menced construction or reconstruction between December 23, 2002 and April 22, 2004, you must demonstrate initial pliance with either the proposed emissions limit or the promulgated emissions limit no later than October 19, 2004 or no later than 180 calendar days after startup of the source, whichever is later, according to 167。(a)(2)(ix).(d) If you menced construction or reconstruction between December 23, 2002 and April 22, 2004, and you chose to ply with the proposed emissions limit when demonstrating initial pliance, you must conduct a second performance test to demonstrate pliance with the promulgated emissions limit by October 19, 2007 or after startup of the source, whichever is later, according to 167。(a)(2)(ix).167。When must I conduct subsequent performance tests?(a) You must conduct subsequent performance tests to demonstrate pliance with all applicable PM or total metal HAP, VOHAP, and TEA emissions limitations in 167。 for your iron and steel foundry no less frequently than every 5 years and each time you elect to change an operating limit or to ply with a different alternative emissions limit, if applicable. The requirement to conduct performance tests every 5 years does not apply to an emissions source for which a continuous emissions monitoring system (CEMS) is used to demonstrate continuous pliance.(b) You must conduct subsequent performance tests to demonstrate pliance with the opacity limit in 167。(a)(7) for your iron and steel foundry no less frequently than once every 6 months.[69 FR 21923, Apr. 22, 2004, as amended at 73 FR 7219, Feb. 7, 2008]167。What test methods and other procedures must I use to demonstrate initial pliance with the emissions limitations?(a) You must conduct each performance test that applies to your iron and steel foundry based on your selected pliance alternative, if applicable, according to the requirements in 167。(e)(1) and the conditions specified in paragraphs (b) through (i) of this section.(b) To determine pliance with the applicable emissions limit for PM in 167。(a)(1) through (6) for a metal melting furnace, scrap preheater, pouring station, or pouring area, follow the test methods and procedures in paragraphs (b)(1) through (6) of this section.(1) Determine the concentration of PM according to the test methods in 40 CFR part 60, appendix A that are specified in paragraphs (b)(1)(i) through (v) of this section.(i) Method 1 or 1A to select sampling port locations and the number of traverse points in each stack or duct. Sampling sites must be located at the outlet of the control device (or at the outlet of the emissions source if no control device is present) prior to any releases to the atmosphere.(ii) Method 2, 2A, 2C, 2D, 2F, or 2G to determine the volumetric flow rate of the stack gas.(iii) Method 3, 3A, or 3B to determine the dry molecular weight of the stack gas.(iv) Method 4 to determine the moisture content of the stack gas.(v) Method 5, 5B, 5D, 5F, or 5I, as applicable, to determine the PM concentration. The PM concentration is determined using only the fronthalf (probe rinse and filter) of the PM catch.(2) Collect a minimum sample volume of 60 dscf of gas during each PM sampling
