Revise text as follows:
21.5.2.1 Testing required by 21.5.2 shall not be required for a primary tank or an interstitial space that continues to
maintain a factory-applied vacuum in accordance with the manufacturer’s instructions. Such components shall be
considered to be tight until such time that the vacuum is broken. Final tightness testing of an interstitial space shall not
be required if the factory-applied vacuum is maintained until:
1) for aboveground tanks, the tank is set on the site at the location where it is intended to be used, or
2) for underground tanks, backfill has been completed to the top of the tank.
The revision proposed in this Public Comment is simply a clarification of the last sentence of this
section in order to eliminate a potential conflict within the section. Obviously, backfill only applies to underground tanks
so aboveground tanks need to be addressed as well for eliminating the need to have a final tightness test of the
interstitial space where a factory-applied vacuum is maintained. So for aboveground tanks that condition is satisfied as
soon as the tank is set on the site at the location where it is intended to be used. Without this revision, it can be
interpreted that the last sentence would not allow the omission of final tightness testing for aboveground tanks where the
interstitial space maintains a factory-applied vacuum, although that appears to be allowed by the first sentence of this
section.

Add a new 22.2.2 to read as follows:
22.2.2 Fire-Resistant Tank. An atmospheric aboveground storage tank with thermal insulation that has been
evaluated for resistance to physical damage and for limiting the heat transferred to the primary tank when exposed to a
hydrocarbon pool fire and is listed in accordance with UL 2080, Standard for Fire Resistant Tanks for Flammable and
Combustible Liquids, or an equivalent test procedure.
This comment was referred to the NFPA 30 Technical Committee on Tank Storage and Piping
Systems by the NFPA 30 Technical Committee on Fundamentals, since the former committee has primary jurisdiction
over issues dealing with storage tanks. See Comment 30-4 (Log #9). The NFPA 30 Technical Committee on Tank
Storage and Piping Systems has added the recommended definition to Chapter 22, but has retained the use of the word
"listed" because the listing is an inherent characteristic of the tank. The Technical Committee has also retained the
reference to equivalent test procedures to make it clear that equivalency in testing and application of criteria is allowed.

Add a new 22.2.3 to read as follows:
22.2.3 Protected Aboveground Tank. An atmospheric aboveground storage tank with integral secondary containment
and thermal insulation that has been evaluated for resistance to physical damage and for limiting the heat transferred to
the primary tank when exposed to a hydrocarbon pool fire and is listed in accordance with ANSI/UL 2085, Standard for
Protected Aboveground Tanks for Flammable and Combustible Liquids, or an equivalent test procedure.
