Dear Mr. Malachowski:
This is in response to your letters of July 19 and September 6, 1996, concerning proposed changes
to the existing Algonquin Liquefied Natural Gas (ALNG) facility in Providence, Rhode Island.
You requested the Office of Pipeline Safety (OPS) to review ALNG’s plans for facility
modifications, and advise your office whether these modifications constitute a “significant
alteration.”
Review of the site plans and description of the ALNG modifications to the existing LNG facility in
Providence, RI, indicate that the following modifications and inspections ALNG proposes to
undertake:
(1) addition of pumps and vaporizers for high pressure sendout,
(2) replacement of the existing low pressure vaporizers,
(3) inspection of the existing LNG tank,
(4) addition of a gas liquefaction system.
Rules governing the applicability of the siting, design, installation, and construction standards are
set forth in 49 CFR §193.2005. Under that section, the new vaporizers and liquefaction facilities
proposed by ALNG would be subject to Part 193. However, the current Part 193 requirements for
siting, design and construction may not be applied to ALNG’s existing storage tank. The storage
tank is not being replaced or relocated, nor is the proposed work on the tank “significant.”
Furthermore, OPS is not in a position to comment on the significance of the alterations to ALNG
facility in relation to the applicability of the “Building Officials and Code Administrators
International, Inc.” (BOCA) standards, because the Department of Transportation has not adopted
the BOCA code.
If we can be of further assistance in this matter, please
contact me or Mr. Mike Israni of my staff at (202)366-4046.
Sincerely,
Richard B. Felder
Associate Administrator
for Pipeline Safety
