Dear Mr. Coffelt:
This responds to your letter dated September 21, 1976, asking that we review a previous
interpretation dated October 21, 1973, regarding 49 CFR 192.357(d). You ask whether that
interpretation permits "service regulators to be installed within a building without venting the
diaphragm breather vent to the outside atmosphere."
Section 192.357(d) reads:
"Each regulator that might release gas in its operation must be vented to the
outside atmosphere."
The October 12, 1973, interpretation essentially provides that Section 192.357(d) does not apply
to a regulator which does not release gas in its operation.
That interpretation was not intended to permit installation of a regulator with a diaphragm breathe
vent inside a building without placing the discharge end of the vent outside the building. Sections
192.199(e) and 192.355(b)(2) are clear that the outlet of each regulator vent must be located
outside.
Sincerely,
Cesar DeLeon
Acting Director
Office of Pipeline
