CFR /  Title 40  /  Part 63  /  Sec. 63.484 Storage vessel provisions.

(a) This section applies to each storage vessel that is assigned to an affected source, as determined by Sec. 63.480(g). Except for those storage vessels exempted by paragraph (b) of this section, the owner or operator of affected sources shall comply with the requirements of Secs. 63.119 through 63.123 and 63.148, with the differences noted in paragraphs (c) through (s) of this section, for the purposes of this subpart.

(b) Storage vessels described in paragraphs (b)(1) through (b)(7) of this section are exempt from the storage vessel requirements of this section.

(1) Storage vessels containing styrene-butadiene latex;

(2) Storage vessels containing latex products other than styrene-butadiene latex, located downstream of the stripping operations;

(3) Storage vessels containing high conversion latex products;

(4) Storage vessels located downstream of the stripping operations at affected sources subject to the back-end residual organic HAP limitation located in Sec. 63.494(a)(1) through (3), that are complying through the use of stripping technology, as specified in Sec. 63.495;

(5) Storage vessels containing styrene;

(6) Storage vessels containing acrylamide; and

(7) Storage vessels containing epichlorohydrin.

(c) When the term ``storage vessel'' is used in Secs. 63.119 through 63.123, the definition of this term in Sec. 63.482 shall apply for the purposes of this subpart.

(d) When the term ``Group 1 storage vessel'' is used in Secs. 63.119 through 63.123, the definition of this term in Sec. 63.482 shall apply for the purposes of this subpart.

(e) When the term ``Group 2 storage vessel'' is used in Secs. 63.119 through 63.123, the definition of this term in Sec. 63.482 shall apply for the purposes of this subpart.

(f) When the emissions averaging provisions of Sec. 63.150 are referred to in Sec. 63.119 and Sec. 63.123, the emissions averaging provisions contained in Sec. 63.503 shall apply for the purposes of this subpart.

(g) When December 31, 1992 is referred to in Sec. 63.119, June 12, 1995 shall apply instead, for the purposes of this subpart.

(h) When April 22, 1994 is referred to in Sec. 63.119, June 19, 2000 shall apply instead, for the purposes of this subpart.

(i) The owner or operator of an affected source shall comply with this paragraph instead of Sec. 63.120(d)(1)(ii) for the purposes of this subpart. If the control device used to comply with Sec. 63.119(e) is also used to comply with any of the requirements found in Secs. 63.485 through 63.501, the performance test required in or accepted by the applicable requirements in Secs. 63.485 through 63.501 is acceptable for demonstrating compliance with Sec. 63.119(e), for the purposes of this subpart. The owner or operator will not be required to prepare a design evaluation for the control device as described in Sec. 63.120(d)(1)(i), if the performance test meets the criteria specified in paragraphs (i)(1) and (i)(2) of this section.

(1) The performance test demonstrates that the control device achieves greater than or equal to the required control efficiency specified in Sec. 63.119(e)(1) or Sec. 63.119(e)(2), as applicable; and

(2) The performance test is submitted as part of the Notification of Compliance Status required by Sec. 63.506(e)(5).

(j) When the term ``range'' is used in Secs. 63.120(d)(3)(i), 63.120(d)(5), and 63.122(g)(2), the term ``level'' shall apply instead, for the purposes of this subpart.

(k) For purposes of this subpart, the monitoring plan required by Sec. 63.120(d)(2) shall specify for which control devices the owner or operator has selected to follow the procedures for continuous monitoring specified in Sec. 63.505. For those control devices for which the owner or operator has selected to not follow the procedures for continuous monitoring specified in Sec. 63.505, the monitoring plan shall include a description of the parameter or parameters to be monitored to ensure that the control device is being properly operated and maintained, an explanation of the criteria used for selection of that parameter (or parameters), and the frequency with which monitoring will be performed (e.g., when the liquid level in the storage vessel is being raised), as specified in Sec. 63.120(d)(2)(i).

(l) For purposes of this subpart, the monitoring plan required by Sec. 63.122(b) shall be included in the Notification of Compliance Status required by Sec. 63.506(e)(5).

(m) When the Notification of Compliance Status requirements contained in Sec. 63.152(b) are referred to in Secs. 63.120, 63.122, and 63.123, the Notification of Compliance Status requirements contained in Sec. 63.506(e)(5) shall apply for the purposes of this subpart.

(n) When the Periodic Report requirements contained in Sec. 63.152(c) are referred to in Secs. 63.120 and 63.122, the Periodic Report requirements contained in Sec. 63.506(e)(6) shall apply for the purposes of this subpart.

(o) When other reports as required in Sec. 63.152(d) are referred to in Sec. 63.122, the reporting requirements contained in Sec. 63.506(e)(7) shall apply for the purposes of this subpart.

(p) When the Initial Notification requirements contained in Sec. 63.151(b) are referred to in Secs. 63.119 through 63.123, for the purposes of this subpart the owner or operator of an affected source need not comply.

(q) When the determination of equivalence criteria in Sec. 63.102(b) are referred to in Sec. 63.121(a), the provisions in Sec. 63.6(g) shall apply for the purposes of this subpart.

(r) When Sec. 63.119(a) requires compliance according to the schedule provisions in Sec. 63.100, owners and operators of affected sources shall instead comply with the requirements in Secs. 63.119(a)(1) through 63.119(a)(4) by the compliance date for storage vessels, which is specified in Sec. 63.481.

(s) In Sec. 63.120(e)(1), instead of the reference to Sec. 63.11(b), the requirements of Sec. 63.504(c) shall apply. [62 FR 46925, Sept. 5, 1996, as amended at 65 FR 38049, June 19, 2000; 76 FR 22588, Apr. 21, 2011]
