Back-end process provisions—reporting. - (a) The owner or operator of an affected source with back-end process operations shall submit the information required in [paragraphs (a)(1) through (a)(3)](#a-1..a-3) of this section, for each back-end process operation at the affected source, as part of the Notification of Compliance Status specified in [§ 63.506(e)(5)](/cfr/40/63.506.md?p=e-5). - (1) **The type of elastomer product processed in the back-end operation.** - (2) The type of process (solution process, emulsion process, etc.) - (3) If the back-end process operation is subject to a residual organic HAP limitation in [§ 63.494(a)(1) through (3)](/cfr/40/63.494.md?p=a-1..a-3), whether compliance will be achieved by stripping technology, or by control or recovery devices. - (b) Each owner or operator of a back-end process operation using stripping to comply with a residual organic HAP limitation in [§ 63.494(a)(1) through (3)](/cfr/40/63.494.md?p=a-1..a-3), and demonstrating compliance by stripper parameter monitoring, shall submit reports as specified in paragraphs [(b)(1)](#b-1) and [(2)](#b-2) of this section. - (1) As part of the Notification of Compliance Status specified in [§ 63.506(e)(5)](/cfr/40/63.506.md?p=e-5), the owner or operator shall submit the information specified in [§ 63.498(c)(1)](/cfr/40/63.498.md?p=c-1). - (2) For organic HAP content/stripper monitoring parameter re-determinations, and the addition of new grades, the information specified in [§ 63.498(c)(1)](/cfr/40/63.498.md?p=c-1) shall be submitted in the next periodic report specified in [§ 63.506(e)(6)](/cfr/40/63.506.md?p=e-6). - (c) Each owner or operator of an affected source with a back-end process operation control or recovery device that shall comply with a residual organic HAP limitation in [§ 63.494(a)(1) through (3)](/cfr/40/63.494.md?p=a-1..a-3), shall submit the information specified in [paragraphs (c)(1) through (3)](#c-1..c-3) of this section as part of the Notification of Compliance Status specified in [§ 63.506(e)(5)](/cfr/40/63.506.md?p=e-5). - (1) The residual organic HAP content, adjusted for the control or recovery device emission reduction, determined in accordance with [§ 63.496(c)(1)](/cfr/40/63.496.md?p=c-1), for each test run in the compliance determination. - (2) The operating parameter level established in accordance with [§ 63.497(c)](/cfr/40/63.497.md?p=c), along with supporting documentation. - (3) The information specified in [paragraphs (c)(3)(i)](#c-3-i) when using a flare, and the information specified in [paragraph (c)(3)(ii)](#c-3-ii) of this section when using a boiler or process heater. - (i) The flare design (i.e., steam-assisted, air-assisted, or non-assisted); all visible emission readings, heat content determinations, flow rate measurements, and exit velocity determinations made during the compliance determination; and all periods during the compliance determination when the pilot flame is absent. - (ii) A description of the location at which the vent stream is introduced into the boiler or process heater. - (d) Whenever a process change, as defined in [§ 63.496(d)](/cfr/40/63.496.md?p=d), is made that causes the redetermination of the compliance status for the back-end process operations subject to a residual organic HAP limitation in [§ 63.494(a)(1) through (3)](/cfr/40/63.494.md?p=a-1..a-3), the owner or operator shall submit a report within 180 days after the process change, as specified in [§ 63.506(e)(7)(iii)](/cfr/40/63.506.md?p=e-7-iii). The report shall include: - (1) A description of the process change; - (2) The results of the redetermination of the compliance status, determined in accordance with [§ 63.496(b)](/cfr/40/63.496.md?p=b), and recorded in accordance with [§ 63.498(d)(1)](/cfr/40/63.498.md?p=d-1), and - (3) Documentation of the re-establishment of a parameter level for the control or recovery device, defined as either a maximum or minimum operating parameter, that indicates proper operation of the control or recovery device, in accordance with [§ 63.497(c)](/cfr/40/63.497.md?p=c) and recorded in accordance with [§ 63.498(d)(2)](/cfr/40/63.498.md?p=d-2). - (e) If an owner or operator uses a control or recovery device other than those listed in [§ 63.497(a)](/cfr/40/63.497.md?p=a) or requests approval to monitor a parameter other than those specified in [§ 63.497(a)](/cfr/40/63.497.md?p=a), the owner or operator shall submit a description of planned reporting and recordkeeping procedures as required under § [63.506(e)(3)](/cfr/40/63.506.md?p=e-3) or [(e)(8)](/cfr/40/63.506.md?p=e-8). The Administrator will specify appropriate reporting and recordkeeping requirements as part of the review of the Precompliance Report or Operating Permit application. - (f) If the back-end process operation is subject to an organic HAP emission limitation in [§ 63.494(a)(4)](/cfr/40/63.494.md?p=a-4), the owner and operator must submit the information specified in paragraphs [(f)(1)](#f-1) and [(2)](#f-2) of this section. - (1) The applicable organic HAP emission limitation determined in accordance with [§ 63.494(a)(4)(i) through (iv)](/cfr/40/63.494.md?p=a-4-i..a-4-iv), shall be submitted no later than 180 days from the date of publication of the final rule amendments in the Federal Register. - (2) Beginning with the first periodic report required to be submitted by [§ 63.506(e)(6)](/cfr/40/63.506.md?p=e-6) that is at least 13 months after the compliance date, the total mass of organic HAP emitted for each of the rolling 12-month periods in the reporting period divided by the total mass of elastomer produced during the corresponding 12-month period, determined in accordance with [§ 63.495(g)(5)](/cfr/40/63.495.md?p=g-5). - (g) Owners and operators subject to [§ 63.494(a)(7)](/cfr/40/63.494.md?p=a-7), must include in the periodic report, the records for the periods specified in [§ 63.498(f)(2)](/cfr/40/63.498.md?p=f-2).
