- (c) **Equipment design and operation.** Each closed-purge, closed-loop, or closed vent system except as provided in [paragraph (d)](#d) of this section shall meet the applicable requirements specified in [paragraphs (c)(1) through (c)(5)](#c-1..c-5) of this section.
  - (1) The system shall return the purged process fluid directly to a process line or fuel gas system meeting the compliance determinations in [§ 63.1015](/cfr/40/63.1015.md) or [§ 63.1002(b)](/cfr/40/63.1002.md?p=b) as appropriate; or
  - (2) Collect and recycle the purged process fluid to a process; or

  - (4) Collect, store, and transport the purged process fluid to a system or facility identified in paragraph [(c)(4)(i)](#c-4-i), [(c)(4)(ii)](#c-4-ii), or [(c)(4)(iii)](#c-4-iii) of this section.
    - (i) A waste management unit as defined in 40 CFR [63.111](/cfr/40/63.111.md) or [40](/cfr/40/40.md) CFR [part 63](/cfr/40/part63.md), [subpart G](/cfr/40/subpartG.md), if the waste management unit is complying with the provisions of [40 CFR part 63](/cfr/40/part63.md), [subpart G](/cfr/40/subpartG.md), applicable to group 1 wastewater streams. If the purged process fluid does not contain any organic HAP listed in table 9 of [40 CFR part 63](/cfr/40/part63.md), [subpart G](/cfr/40/subpartG.md), the waste management unit need not be subject to, and operated in compliance with the requirements of [40 CFR part 63](/cfr/40/part63.md), [subpart G](/cfr/40/subpartG.md), applicable to subject wastewater steams provided the facility has a National Pollution Discharge Elimination System (NPDES) permit or sends the wastewater to an NPDES-permitted facility.
    - (ii) A treatment, storage, or disposal facility subject to regulation under 40 CFR part [262](/cfr/40/part262.md), [264](/cfr/40/part264.md), 265, or 266; or
    - (iii) A facility permitted, licensed, or registered by a State to manage municipal or industrial solid waste, if the process fluids are not hazardous waste as defined in [40 CFR part 261](/cfr/40/part261.md).
  - (5) Containers that are part of a closed-purge system must be covered or closed when not being filled or emptied.
- (d) **In-situ sampling systems.** In-situ sampling systems and sampling systems without purges are exempt from the requirements of paragraphs [(b)](#b) and [(c)](#c) of this section.
