Description of Proposed Guidance Document Changes

The Office of Drinking Water (ODW) has developed guidelines for waterworks with permanent chlorination equipment that is installed and operating to respond to water main breaks and depressurization events. This guidance classifies certain water line breaks as not needing a boil water advisory, and recommends boil water advisories only in events likely to involve contamination intrusion. This will result in fewer boil water advisories and waterworks will have specific guidelines for when ODW recommends they issue a boil water advisory. Waterworks customers will receive fewer boil water advisories and, when there is an advisory, will be more likely to follow the recommendation to boil their water prior to consumption. ODW based the guidelines on Effective Microbial Control Strategies for Main Breaks and Depressurization, Water Research Foundation Project #4307. The Waterworks Advisory Committee reviewed and accepted the guidelines prior to this notice.
