§ 63.7895 What emissions limitations and work practice standards must I meet for tanks?
(a) You must control HAP emissions from each new and existing tank subject to § 63.7886(b)(1)(i) according to emissions limitations and work practice standards in this section that apply to your affected tanks.
(b) For each affected tank, you must install and operate air pollution controls that meet the requirements in paragraphs (b)(1) through (4) of this section that apply to your tank.
(1) Unless your tank is used for a waste stabilization process, as defined in § 63.7957, you must determine the maximum HAP vapor pressure (expressed in kilopascals (kPa)) of the remediation material placed in your tank using the procedures specified in § 63.7944.
(2) If the maximum HAP vapor pressure of the remediation material you place in your tank is less than 76.6 kPa, then you must determine which tank level controls (i.e., Tank Level 1 or Tank Level 2) apply to your tank as shown in Table 2 of this subpart, and based on your tank's design capacity (expressed in cubic meters (m3)) and the maximum HAP vapor pressure of the remediation material you place in this tank. If your tank is required by Table 2 of this subpart to use Tank Level 1 controls, then you must meet the requirements in paragraph (c) of this section. If your tank is required by Table 2 of this subpart to use Tank Level 2 controls, then you must meet the requirements in paragraph (d) of this section
(3) If maximum HAP vapor pressure of the remediation material you place in your tank is 76.6 kPa or greater, then the tank must use one of the Tank Level 2 controls specified in paragraphs (d)(3) through (5) of this section. Use of floating roofs under paragraph (d)(1) or (2) of this section is not allowed for tanks managing these remediation materials.
(4) A tank used for a waste stabilization process, as defined in § 63.7957, must use one of Tank Level 2 controls, as specified in paragraph (d) of this section, that is appropriate for your waste stabilization process.
(c) If you use Tank Level 1 controls, you must install and operate a fixed roof according to the requirements in § 63.902. As an alternative to using this fixed roof, you may choose to use one of Tank Level 2 controls in paragraph (d) of this section.
(d) If you use Tank Level 2 controls, you must meet the requirements of one of the options in paragraphs (d)(1) through (5) of this section.
(1) Install and operate a fixed roof with an internal floating roof according to the requirements in § 63.1063(a)(1)(i), (a)(2), and (b); or
(2) Install and operate an external floating roof according to the requirements in § 63.1063(a)(1)(ii), (a)(2), and (b); or
(3) Install and operate a fixed roof vented through a closed vent system to a control device according to the requirements in § 63.685(g). You must meet the emissions limitations and work practice standards in § 63.7925 that apply to your closed vent system and control device; or
(4) Install and operate a pressure tank according to the requirements in § 63.685(h); or
(5) Locate the tank inside a permanent total enclosure and vent emissions from the enclosure through a closed vent system to a control device that is an enclosed combustion device according to the requirements in § 63.685(i). You must meet the emissions limitations and work practice standards in § 63.7925 that apply to your closed vent system and control device.
(e) As provided in § 63.6(g), you may request approval from the EPA to use an alternative to the work practice standards in this section that apply to your tanks. If you request for permission to use an alternative to the work practice standards, you must submit the information described in § 63.6(g)(2).
