Rule 62-555.330 is being amended to incorporate the current or third edition of American Water Works Association (AWWA) Manual M14 instead of the second edition of this manual, which is no longer available from the publisher. Subsection 62-555.360(1) is being amended to clarify that cross-connections are prohibited except where an appropriate type of backflow preventer is installed; to clarify that a PWS may interconnect to another PWS of the same type without installing a backflow preventer; and to clarify appropriate types of backflow preventers for various applications. Subsection 62-555.360(2) is being amended to require that only CWSs must establish and implement a cross-connection control program; to clarify that the purpose of a CWS cross-connection control program is to protect the CWS from contamination caused by cross-connections at customers’ premises; and to add Tables 62-555.360-1 and 62-555.360-2. Table 62-555.360-1 clarifies the minimum components that each CWS shall include in its written cross-connection control plan in order to accomplish recommended practices in AWWA Manual M14, and this table also modifies recommended practices in AWWA Manual M14 by allowing biennial instead of annual testing of backflow preventer assemblies required at service connections from CWSs to residential premises. Table 62-555.360-2 clarifies the categories of customers for which each CWS shall require or provide minimum backflow protection at the water service connection in order to accomplish recommended practices in AWWA Manual M14, and this table also modifies recommended practices in AWWA Manual M14 by allowing a dual check device to be used as backflow protection at service connections from CWSs to residential premises where there is any type of auxiliary or reclaimed water system. Additionally, Subsection 62-555.360(2) is being amended to require large CWSs to submit annual cross-connection control program reports using a brief new two-page form. Subsection 62-555.360(3) is being amended to clarify the action PWSs are required to take upon discovery of a prohibited cross-connection. Subsections 62-555.360(4) and 62-555.360(5) are being deleted as unnecessary because of the clarifications being made to subsections 62-555.360(1) through 62-555.360(3). Rule 62-555.900 is being amended to add new Form 62-555.900(13) to the list of forms in this rule.
