Volumetric flow rate.
Volumetric flow rate. The process vent volumetric flow rate (QS) in standard cubic meters per minute at 20 C (68 F) shall be determined as specified in paragraphs (d)(1) and (2) of this section and shall be recorded as specified in 65.66(b):
(1) Use Method 2, 2A, 2C, or 2D of appendix A of 40 CFR part 60, as appropriate. If the process vent tested passes through a final steam jet ejector and is not condensed, the stream volumetric flow shall be corrected to 2.3 percent moisture; or
(2) The engineering assessment procedures in paragraph (i) of this section can be used for determining volumetric flow rates.
