The BLM will list on www.blm.gov the make, model, and size of isolating flow conditioner that is approved for use in conjunction with a flange-tapped orifice plate, so long as the isolating flow conditioner is installed, operated, and maintained in compliance with the requirements of this section. Approval of a particular make and model is obtained as prescribed in this section.

- (b) The operator or manufacturer must test the flow conditioner under API 14.3.2, Annex D (incorporated by reference, see [§ 3175.30](/cfr/43/3175.30.md)) and submit all test data to the BLM.
- (c) The PMT will review the test data to ensure that the device meets the requirements of API 14.3.2, Annex D (incorporated by reference, see [§ 3175.30](/cfr/43/3175.30.md)) and make a recommendation to the BLM to either approve use of the device, disapprove use of the device, or approve it with conditions for its use.
- (d) If approved, the BLM will add the approved make and model, and any applicable conditions of use, to the list maintained at www.blm.gov.
