Van Milligen, City Manager SUBJECT: Adoption of Standard Operating Procedures for Sanitary and Unsanitary (inc. Water Main Breaks) Conditions DATE: June 28, 2017 Water Department Manager Denise Ihrig recommends City Council adoption of the revised City of Dubuque Water Department Standard Operating Procedures for Sanitary and Unsanitary (inc. Water Main Breaks) Conditions. The Iowa Administrative Code (the Code) 567-42.1(2) identifies the notification and procedure requirements for publicly owned and operated water supplies. The purpose of the notification procedure is to protect public health. In August 2016, the Iowa DNR issued revised guidance available to community water supplies titled the Iowa Main Break and Depressurization Guidance. The guidance document "is intended to provide guidance to public water supply owners and operators in evaluating and responding to pressure loss situations from distribution system issues such as main breaks, valve repairs, or extreme fire flows, and operational disruptions such pump failure, power outage, telemetry [SCADA] failure, source failure, or storage depletion". Anytime, the water supply is subject to disruption, the protection of public health and safety is the priority and the City of Dubuque is working to ensure these disruptions are minimized and follow the necessary critical steps throughout the process to restore service to its customers as quickly and safely as possible. The development of the City's Standard Operating Procedures for sanitary and unsanitary conditions includes specific details including need to know information; a communication plan; a list of situations that would lead to issuance of a boil water advisory; contact lists; a step by step process on how to handle sanitary and unsanitary situations including main breaks; and reference materials used to assist Water Department staff in responding to main breaks or other situations where the public water supply has been interrupted. I concur with the recommendation and respectfully request Mayor and City Council approval. J 1 r �1L�1#'L y ttrt�A&Znt.- Mic ael C.

Masterpiece on the Mississippi 2007-2012-2013 TO: Michael Van Milligen, City Manager FROM: Denise Ihrig, Water Department Manager DATE: June 27, 2017 RE: Adoption of Standard Operating Procedures for Sanitary and Unsanitary (inc.Water Main Breaks) Conditions PURPOSE The purpose of this memorandum is to request the formal adoption by City Council of the revised City of Dubuque Water Department Standard Operating Procedures for Sanitary and Unsanitary (inc.Water Main Break) Conditions. BACKGROUND The Iowa Administrative Code (the Code) 567-42.1(2) identifies the notification and procedure requirements for publicly owned and operated water supplies. The purpose of the notification procedure is to protect public health in the event the public water supply does not comply with: maximum contaminant levels, maximum residual disinfection level, treatment technique, monitoring requirements, and testing procedures meeting the federal Safe Drinking Water Act. The Code requires that "Each owner or operator of a public water system must give notice for all violations of public drinking water rules and for other situations". The Code is further described and relayed to communities by the Iowa Department of Natural Resources (Iowa DNR), which identifies other situations, as a treatment or distribution system failure that "significantly increases the potential for drinking water contamination" and "with significant potential to have serious adverse effects on human health as a result of short-term exposure". The Iowa DNR assists local water supplies with the issuance of guidance on how to correctly manage instances where a community water supply may not be able to meet the Code, such as in the instances of a main break or pressure loss in the distribution system. In August 2016, the Iowa DNR issued revised guidance available to community water supplies titled the Iowa Main Break and Depressurization Guidance. The guidance document "is intended to provide guidance to public water supply owners and operators in evaluating and responding to pressure loss situations from distribution system issues such as main breaks, valve repairs, or extreme fire flows, and operational disruptions such pump failure, power outage, telemetry [SCADA] failure, source failure, or storage depletion". Anytime, the water supply is subject to disruption, the protection of public health and safety is the priority and the City of Dubuque is working to ensure these disruptions are minimized and follow the necessary critical steps throughout the process to restore service to its customers as quickly and safely as possible. DISCUSSION City experiences a Significant Main Break The City experienced a significant disruption to its water service on May 3rd, 2016. A 20- inch water main break occurred at the intersection of Johnson Street and 22nd Street. The event resulted in loss of pressure in the distribution system and depletion of storage tank. Working with the Iowa DNR, the City issued a boil advisory in the impacted pressure zone. The City was able to localize the main break reducing the area impacted and was able to restore service to the localized area within 16 hours. During the main break, City departments, including the City Manager's office, Public Works, Engineering, Health Services and the Public Information office assembled to determine the extent of the required public notification. With assistance from the City's Public Information Officer, residents and businesses were notified via a news release, the City's Facebook page, the City's Twitter feed, and other news outlets including the Telegraph Herald, Radio Dubuque, KCRG and KWWL. A CodeRed notification was also issued in the boil advisory area which reached more than 8,000 registered users. Development of a City Standard Operating Procedure Following the event, the Water Department, Fire Department, Emergency Management, Health Services Department, Engineering and the City Manager convened to analyze the May 2016 water main break event and review other situations that may lead to an unsanitary condition. From the discussion, it was determined, a standard operating procedure be developed from the Iowa DNR's Iowa Main Break and Depressurization Guidance Document (August 2016) (Guidance Document) to assist the City in responding to routine and significant main breaks. The standard operating procedure, would centralize all information necessary to respond to a main break or other situations that may lead to an unsanitary condition. The DNR's field office representative Amber Sauser was consulted during development of the procedure and provided additional guidance on how to incorporate the Iowa DNR's Guidance Document. The Iowa DNR's Guidance Document identifies the AWWA Standard to be followed; boil water advisory situations; minimum bacteria sampling requirements; when to contact the DNR field office; and information to be included in a communication plan. In addition, it summarizes how to respond to an escalating situation from a sanitary water main repair to an unsanitary condition leading to a boil water advisory. The summary is an appendix to the Guidance Document and is titled Appendix 3: Main Break Types and Responses. A copy of Appendix 3 is attached. The development of the City's Standard Operating Procedures for sanitary and unsanitary conditions includes specific details including need to know information; a communication plan; a list of situations that would lead to issuance of a boil water advisory; contact lists; a step by step process on how to handle sanitary and unsanitary situations including main 2 breaks; and reference materials used to assist Water Department staff in responding to main breaks or other situations where the public water supply has been interrupted. The document was made possible with assistance from key City departments including the City Manager's office, Utility Billing, Public Information, Information Service, Health Services, Fire Department, Emergency Management, and City Engineering. Each department lending expertise in communication and emergency response. The Communication Plan details how residents, businesses, regulatory bodies, and City departments are to be notified including what method of notification. The City has several notification tools available. The use of each notification tool is further identified based upon the area affected and if there is an escalating situation. For example, door hangers are a popular method of notifying residents and businesses of a water supply disruption. The City has created different door hangers for each situation. Using the Guidance Document's Appendix 3, a Controlled Pipe Repair with depressurization after Shutdown without Opening the Pipe would prompt the City to advise customers to flush their plumbing. The appropriate door hanger the City would issue for residents or businesses located in the shutdown area would be an Out of Service: Notice to Flush Service Line. Whereas, in an area where there is an Uncontrolled Pipe Break with Loss of Sanitary Conditions during Repair would require a Boil Water Advisory. Again, the City has a door hanger with clear direction on customers should proceed with boiling water until further. Copies of each type of door hanger may be found in the attachments located in the Standard Operating Procedure for Sanitary and Unsanitary (inc. Water Main Break) Conditions document. Other notification tools available to the City include Facebook, Twitter, News Releases, the Water Department Website, Code Red, and in Barrington Lakes, Cedar Crest, and Wildwood Estates (Vernon Water system) mobile, free standing signage. A copy of the Water Department's proposed Standard Operating Procedure for Sanitary and Unsanitary (Inc. Water Main Break) Conditions is attached. REQUESTED ACTION I respectfully request the formal adoption by City Council of the revised City of Dubuque Water Department Standard Operating Procedures for Sanitary and Unsanitary (Inc. Water Main Break) Water Distribution Conditions.
