# §63.7916. How do I demonstrate initial compliance with the emissions limitations and work practice standards for transfer systems?

- (a) You must demonstrate initial compliance with the emissions limitations and work practice standards in [§ 63.7915](/cfr/40/63.7915.md) that apply to your affected transfer systems by meeting the requirements in [paragraphs (b) through (e)](#b..e) of this section, as applicable to your transfer systems.
- (b) You must demonstrate initial compliance of each individual drain system using controls according to [§ 63.7915(b)](/cfr/40/63.7915.md?p=b) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you have met the requirements in [paragraphs (b)(1) through (3)](#b-1..b-3) of this section.
  - (1) You have installed air emission controls for each individual drain system and junction box according to the requirements in § [63.962(a)](/cfr/40/63.962.md?p=a) and [(b)](/cfr/40/63.962.md?p=b), and you have records documenting the installation and design.
  - (2) You will operate the air emission controls according to the requirements in [§ 63.962(b)(5)](/cfr/40/63.962.md?p=b-5).
  - (3) You have performed an initial visual inspection of each individual drain system according to the requirements in [§ 63.964(a)](/cfr/40/63.964.md?p=a), and you have records documenting the inspection results.
- (c) You must demonstrate initial compliance of each transfer system using covers according to [§ 63.7915(c)(1)](/cfr/40/63.7915.md?p=c-1) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you have met the requirements in [paragraphs (c)(1) through (3)](#c-1..c-3) of this section.
  - (1) Each transfer system is equipped with covers and closure devices according to the requirements in [§ 63.689(d)(1) through (4)](/cfr/40/63.689.md?p=d-1..d-4), and you have records documenting the design and installation.
  - (2) You have performed an initial inspection of each cover and its closure devices for defects according to the requirements in [§ 63.695(d)(1) through (5)](/cfr/40/63.695.md?p=d-1..d-5), and you have records documenting the inspection results.
  - (3) You will operate each cover and its closure devices according to the requirements in [§ 63.689(5)](/cfr/40/63.689.md?p=5).
- (d) You must demonstrate initial compliance of each transfer system that consists of hard piping according to [§ 63.7915(c)(2)](/cfr/40/63.7915.md?p=c-2) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you have met the requirements in paragraphs [(d)(1)](#d-1) and [(2)](#d-2) of this section.
  - (1) You have installed a transfer system that consists entirely of hard piping and meets the requirements in [§ 63.7915(c)(2)](/cfr/40/63.7915.md?p=c-2), and you have records documenting the design and installation.
  - (2) You have performed an initial inspection of the entire transfer system to verify that all joints or seams between the pipe sections are permanently or semi-permanently sealed (e.g., a welded joint between two sections of metal pipe or a bolted and gasketed flange), and you have records documenting the inspection results.
- (e) You must demonstrate initial compliance of each transfer system that is enclosed and vented to a control device according to [§ 63.7915(e)(3)](/cfr/40/63.7915.md?p=e-3) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you have met the requirements in paragraphs [(e)(1)](#e-1) and [(2)](#e-2) of this section.
  - (1) You have installed a transfer system that is designed and operated such that an internal pressure in the vapor headspace in the enclosure is maintained at a level less than atmospheric pressure when the control device is operating, and you have records documenting the design and installation.
  - (2) You have met each applicable requirement for demonstrating initial compliance with the emission limitations and work practice standards for a closed vent system and control device in [§ 63.7926](/cfr/40/63.7926.md).
