Dear Mr. Greenwalt:

Your letter of January 11, 1972, addressed to the Secretary of the Hazardous Materials Regulations Board has been forwarded to me for reply.

In your letter, you inquire:

"As we interpret the different government regulations, the testing of the relief valves on our LPG storage tanks is covered by NFPA Standard No. 59 as referenced in Paragraph 192.11 of Part 192 in Title 49 of the Federal Regulations.

Paragraph 62 of NFPA Standard No. 59 recognizes the 5 year test period for relief valves on LPG storage tanks. Please advise if our interpretation is incorrect."

Your interpretation is correct. The notice to which you refer, Notice 71-27; Docket No. BM-6D, is a Notice of Proposed Rule Making involving Section 195.428. This section is contained in Part 195 titled "Transportation of Liquids by Pipeline" (49 CFR Part 195).Pipeline carriers who transport liquid hazardous materials and petroleum in interstate and foreign commerce are subject to the regulations in Part 195. Operators of natural gas pipeline facilities are subject to the regulations in Part 192 (49 CFR Part 192).

Please contact me if I can be of any more assistance in this matter.
