The IAPMO Standards Council on Dec. 18 issued one tentative interim amendment (TIA) affecting the 2021 edition of the Uniform Plumbing Code (UPC ^®).

TIA UPC 001-21 added text in UPC Table 603.2 pertaining to the installation of atmospheric vacuum breakers.

The TIA was balloted through the Plumbing Technical Committee in accordance with the Regulations Governing Committee Projects to determine if there existed the necessary three-fourths majority support on technical merit and emergency nature to establish the recommendation for issuance. In the case of TIA UPC- 001-21, the letter ballot passed on both accounts.

In determining whether or not to issue a TIA, the Standards Council looks to the Technical Committee letter ballot for a recommendation of support. Upon a full review and consideration of all the information available to it, the Council agreed with the substantiation submitted by the proponent and thus voted to accept the recommendation of the Technical Committee and issue TIA UPC 001-21.

TIAs are proposals based on the determination of an emergency nature requiring prompt action to amend code that contains an error or omission that was overlooked during the regular code development process, contains a conflict within the document or with another IAPMO document, or to correct a hazard, promote an advancement in safeguarding the public or provide an opportunity to correct an adverse impact on a product or method of installation.
