CFR /  Title 40  /  Part 63  /  Sec. 63.502 Equipment leak and heat exchange system provisions.

(a) Equipment leak provisions. The owner or operator of each affected source, shall comply with the requirements of subpart H of this part, with the exceptions noted in paragraphs (b) through (m) of this section. Surge control vessels required to be controlled by subpart H may, alternatively, comply with the Group 1 storage vessel provisions specified in Sec. 63.484.

(b) Surge control vessels and bottoms receivers described in paragraphs (b)(1) through (b)(7) of this section are exempt from the requirements contained in Sec. 63.170.

(1) Surge control vessels and bottoms receivers that receive only styrene-butadiene latex;

(2) Surge control vessels and bottoms receivers that receive latex products other than styrene-butadiene latex, located downstream of the stripping operations;

(3) Surge control vessels and bottoms receivers that receive only high conversion latex products;

(4) Surge control vessels and bottoms receivers 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) Surge control vessels and bottoms receivers that receive only styrene;

(6) Surge control vessels and bottoms receivers that receive only acrylamide; and

(7) Surge control vessels and bottoms receivers that receive only epichlorohydrin.

(c) The compliance date for the equipment leak provisions in this section is provided in Sec. 63.481(d). Whenever subpart H of this part refers to the compliance dates specified in any paragraph contained in Sec. 63.100, the compliance dates listed in Sec. 63.481(d) shall instead apply, for the purposes of this subpart. When Sec. 63.182(c)(4) refers to ``sources subject to subpart F,'' the phrase ``sources subject to this subpart'' shall apply, for the purposes of this subpart. In addition, extensions of compliance dates are addressed by Sec. 63.481(e) instead of by Sec. 63.182(a)(6), for the purposes of this subpart.

(d) For an affected source producing polybutadiene rubber or styrene butadiene rubber by solution, the conditions in paragraphs (d)(1), (d)(2), and (d)(3) of this section are applicable.

(1) Indications of liquids dripping, as defined in subpart H of this part, from bleed ports in pumps and agitator seals in light liquid service, shall not be considered a leak. For the purposes of this subpart, a ``bleed port'' is a technologically-required feature of the pump or seal whereby polymer fluid used to provide lubrication and/or cooling of the pump or agitator shaft exits the pump, thereby resulting in a visible dripping of fluid.

(2) For reciprocating pumps in heavy liquid service, owners and operators are not required to comply with the requirements in Sec. 63.169 and associated recordkeeping and reporting requirements.

(3) Reciprocating pumps in light liquid service are exempt from Sec. 63.163 and associated recordkeeping and reporting requirements, if recasting the distance piece or reciprocating pump replacement would be necessary to comply with that section.

(e) Owners and operators of an affected source subject to this subpart are not required to submit the Initial Notification required by Sec. 63.182(a)(1) and Sec. 63.182(b).

(f) As specified in Sec. 63.506(e)(5), the Notification of Compliance Status required by Sec. 63.182(a)(2) and Sec. 63.182(c) shall be submitted within 150 days (rather than 90 days) of the applicable compliance date specified in Sec. 63.481(d) for the equipment leak provisions.

(g) The information specified by Sec. 63.182(a)(3) and Sec. 63.182(d) (i.e., Periodic Reports) shall be submitted as part of the Periodic Reports required by Sec. 63.506(e)(6).

(h) If specific items of equipment, comprising part of a process unit subject to this subpart, are managed by different administrative organizations (e.g., different companies, affiliates, departments, divisions, etc.), those items of equipment may be aggregated with any EPPU within the affected source for all purposes under subpart H of this part, providing there is no delay in achieving the applicable compliance date.

(i) When Sec. 63.166(b)(4)(i) refers to Table 9 of subpart G of this part, the owner or operator is only required to consider organic HAP listed on Table 9 of subpart G of this subpart that are also listed on Table 5 of this subpart.

(j) When the provisions of subpart H of this part specify that Method 18, 40 CFR part 60, appendix A shall be used, either Method 18 or Method 25A, 40 CFR part 60, appendix A may be used for the purposes of this subpart. The use of Method 25A, 40 CFR part 60, appendix A shall conform with the requirements in paragraphs (j)(1) and (j)(2) of this section.

(1) The organic HAP used as the calibration gas for Method 25A, 40 CFR part 60, appendix A shall be the single organic HAP representing the largest percent by volume of emissions.

(2) The use of Method 25A, 40 CFR part 63, appendix A is acceptable if the response from the high-level calibration gas is at least 20 times the standard deviation of the response from the zero calibration gas when the instrument is zeroed on the most sensitive scale.

(k) An owner or operator using a flare to comply with the requirements of this section shall conduct a compliance demonstration as specified in Sec. 63.504(c).

(l) When the term ``equipment'' is used in subpart H of this part, the definition of this term in Sec. 63.482(b) shall apply for the purposes of this subpart.

(m) The phrase ``the provisions of subparts F, I, or U of this part'' shall apply instead of the phrase ``the provisions of subpart F or I of this part'' throughout Secs. 63.163 and 63.168, for the purposes of this subpart. In addition, the phrase ``subparts F, I, and U'' shall apply instead of the phrase ``subparts F and I'' in Sec. 63.174(c)(2)(iii), for the purposes of this subpart.

(n) Heat exchange system provisions. The owner or operator of each affected source shall comply with the requirements of Sec. 63.104 for heat exchange systems, with the exceptions noted in paragraphs (n)(1) through (n)(5) of this section.

(1) When the term ``chemical manufacturing process unit'' is used in Sec. 63.104, the term ``elastomer product process unit'' (or EPPU) shall apply for the purposes of this subpart, with the exception noted in paragraph (n)(2) of this section.

(2) When the phrase ``a chemical manufacturing process unit meeting the conditions of Sec. 63.100(b)(1) through (b)(3) of this subpart, except for chemical manufacturing process units meeting the condition specified in Sec. 63.100(c) of this subpart'' is used in Sec. 63.104(a), the term ``an EPPU, except for EPPUs meeting the condition specified in Sec. 63.480(b)'' shall apply for the purposes of this subpart.

(3) When Sec. 63.104 refers to Table 4 of subpart F of this part or Table 9 of subpart G of this part, the owner or operator is only required to consider organic HAP listed on Table 5 of this subpart.

(4) When Sec. 63.104(c)(3) specifies the monitoring plan retention requirements, and when Sec. 63.104(f)(1) refers to the record retention requirements in Sec. 63.103(c)(1), the requirements in Sec. 63.506(a) and Sec. 63.506(h) shall apply, for the purposes of this subpart.

(5) When Sec. 63.104(f)(2) requires information to be reported in the Periodic Reports required by Sec. 63.152(c), the owner or operator shall instead report the information specified in Sec. 63.104(f)(2) in the Periodic Reports required by Sec. 63.506(e)(6), for the purposes of this subpart.

(6) The compliance date for heat exchange systems subject to the provisions of this section is specified in Sec. 63.481(d)(6). [62 FR 46925, Sept. 5, 1996, as amended at 62 FR 37722, July 15, 1997; 65 FR 38070, June 19, 2000; 76 FR 22592, Apr. 21, 2011]
