PRI Gasco, Inc. — Pipeline Safety Interpretation

Page 1PI-85-0102 April 29, 1985 Mr. David Y. Morikawa Project Engineer PRI Gasco, Inc. PRI Tower 733 Bishop Street P. O. Box 3379 Honolulu, Hawaii 96842 Dear Mr. Morikawa: The Installation of a regulator in an alcove with a louvered door facing the outside of a building would not meet §§192.355(b)(2) or 192.357(d). Under these regulations, the vent outlet of a regulator installed inside a building must be located outside to assure that any gas escaping through the vent is released in the outside atmosphere. Sincerely, Original signed by Richard L. Beam Associate Director for Pipeline Safety Regulation Materials Transportation Bureau#

Department of Transportation Research and Special Programs Administration 400 Seventh Street, S.W. Washington, D.C. 20590 Dear Mr. Beam: Subject: Code of Federal Regulations Title 49, Part 192, Subpart H Sections 192.355 and 192.357 require customer regulators to be vented "freely into the atmosphere," and "to the outside atmosphere." For the installation of a customer's meter set assembly in an alcove with a louvered door facing the outside of building, would this satisfy the customer regulator requirements, as required by this section? Your clarification and comments in this area will be appreciated. Very truly yours, David Y. Morikawa Project Engineer#
