(3)

As an alternative to meeting the standards in paragraph (b)(2) of this section for containers with a capacity greater than 0.46 m3, if you determine that either of the conditions in paragraph (b)(3)(i) or (ii) apply to the remediation material placed in your container, then you may use controls according to the standards for Container Level 1 controls as specified in § 63.922. § 63.922(d)(4) and (5) do not apply for the purposes of this subpart if your initial startup date is after September 3, 2019; § 63.922(d)(4) and (5) do not apply for the purposes of this subpart for any source after January 6, 2021.

(c)

At times when a container having a design capacity greater than 0.1 m3 is used for treatment of a remediation material by a waste stabilization process as defined in § 63.7957, you must control air emissions from the container during the process whenever the remediation material in the container is exposed to the atmosphere according to the standards for Container Level 3 controls as specified in § 63.924. You must meet the emissions limitations and work practice standards in § 63.7925 that apply to your closed vent system and control device. § 63.924(d) does not apply for the purposes of this subpart if your initial startup date is after September 3, 2019; § 63.924(d) does not apply for the purposes of this subpart for any source after January 6, 2021.
