The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association.

SCOPE
This standard describes coating systems for coating and recoating the inside and outside surfaces of steel tanks used for potable water storage in water supply service. Coating systems for bolted steel tanks are not described in this standard (see ANSI/AWWA D103). This standard provides the minimum requirements for coating steel water-storage tanks, including materials, coating systems, surface preparation, application, and inspection and testing.

MAJOR REVISIONS

Major revisions made to the standard in this revision include the following:

1. AMPP Coating Standard No. 29 on Zinc-Pigmented Primer, Performance Based, has been added as a reference document for outside coating systems OCS-2, OCS-3, OCS-4, and OCS-6.
2. AMPP Coating Standard No. 29 on Zinc-Pigmented Primer, Performance Based, has been added as a reference document for inside coating systems ICS-3, ICS-5, and ICS-6.
3. Provisions for primer, intermediate, and finish coats have been modified in Sec. 4.7.2 and Sec. 4.7.3.
4. General information on AMPP Coating Standard No. 29 has been added to Appendix Sec. A.1.
5. Guidance on overcoating considerations has been expanded in Appendix Sec. A.2 and Sec. A.3.
6. Guidance on caulking joints in roof structures on existing tanks has been expanded in Appendix Sec. A.5.7.
