# §60.5394c. What GHG standards apply to process controller designated facilities?


Each process controller designated facility must comply with the GHG standards in this section.

- (a) You must design and operate each process controller designated facility with zero methane emissions to the atmosphere, except as provided in [paragraph (b)](#b) of this section.
  - (1) If you comply by routing the emissions to a process, emissions must be routed to a process through a closed vent system.
  - (2) If you comply by using a self-contained natural gas-driven process controller, you must design and operate each self-contained natural gas-driven process controller with no identifiable emissions, as demonstrated by [§ 60.5416c(b)](/cfr/40/60.5416c.md?p=b).
- (b) For each process controller designated facility located at a site in Alaska that does not have access to electrical power, you may comply with either paragraphs [(b)(1)](#b-1) and [(2)](#b-2) of this section or with [paragraph (b)(3)](#b-3) of this section, instead of complying with [paragraph (a)](#a) of this section.
  - (1) With the exception of natural gas-driven continuous bleed controllers that meet the condition in [paragraph (b)(1)(i)](#b-1-i) of this section and that comply with [paragraph (b)(1)(ii)](#b-1-ii) of this section, each natural gas-driven continuous bleed process controller in the process controller designated facility must have a bleed rate less than or equal to 6 standard cubic feet per hour (scfh).
    - (i) A natural gas-driven continuous bleed process controller with a bleed rate higher than 6 scfh may be used if the requirements of [paragraph (b)(1)(ii)](#b-1-ii) of this section are met.
    - (ii) You demonstrate that a natural gas-driven continuous bleed controller with a bleed rate higher than 6 scfh is required. The demonstration must be based on the specific functional need, including but not limited to response time, safety, or positive actuation.
  - (2) Each natural gas-driven intermittent vent process controller in the process controller designated facility must comply with the requirements in paragraphs [(b)(2)(i)](#b-2-i) and [(ii)](#b-2-ii) of this section.
    - (i) Each natural gas-driven intermittent vent process controller must not emit to the atmosphere during idle periods.
    - (ii) You must monitor each natural gas-driven intermittent vent process controller to ensure that it is not emitting to the atmosphere during idle periods, as specified in [paragraphs (b)(2)(ii)(A) through (C)](#b-2-ii-A..b-2-ii-C) of this section.
      - (A) Monitoring must be conducted at the same frequency as specified for fugitive emissions components designated facilities located at the same type of site, as specified in [§ 60.5397c(g)](/cfr/40/60.5397c.md?p=g).
      - (B) You must include the monitoring of each natural gas-driven intermittent vent process controller in the monitoring plan required in [§ 60.5397c(b)](/cfr/40/60.5397c.md?p=b).
      - (C) When monitoring identifies emissions to the atmosphere from a natural gas-driven intermittent vent controller during idle periods, you must take corrective action by repairing or replacing the natural gas-driven intermittent vent process controller within 5 calendar days of the date the emissions to the atmosphere were detected. After the repair or replacement of a natural gas-driven intermittent vent process controller, you must re-survey the natural gas-driven intermittent vent process controller within five days to verify that it is not venting emissions during idle periods.
  - (3) You must reduce methane emissions from all controllers in the process controller designated facility by 95.0 percent. You must route emissions to a control device through a closed vent system that meets the conditions specified in [§ 60.5412c](/cfr/40/60.5412c.md).
- (c) If you route process controller emissions to a process or a control device, you must route the process controller designated facility emissions through a closed vent system that meets the requirements of § [60.5411c(a)](/cfr/40/60.5411c.md?p=a) and [(c)](/cfr/40/60.5411c.md?p=c).
- (d) You must demonstrate initial compliance with standards that apply to process controller designated facilities as required by [§ 60.5410c(e)](/cfr/40/60.5410c.md?p=e).
- (e) You must demonstrate continuous compliance with standards that apply to process controller designated facilities as required by [§ 60.5415c(g)](/cfr/40/60.5415c.md?p=g).
- (f) You must perform the reporting as required by § [60.5420c(b)(1)](/cfr/40/60.5420c.md?p=b-1), [(6)](/cfr/40/60.5420c.md?p=b-6) and [(10) through (12)](/cfr/40/60.5420c.md?p=b-10..b-12), as applicable, and the recordkeeping as required by § [60.5420c(c)(5)](/cfr/40/60.5420c.md?p=c-5), [(7)](/cfr/40/60.5420c.md?p=c-7), and [(9) through (12)](/cfr/40/60.5420c.md?p=c-9..c-12), as applicable.
