Storage tank, cross-connection control, public notice, and sanitary survey rules stakeholder information

The department is proposing minor modifications to the Storage Tank Rule and Backflow Prevention and Cross-Connection Control Rule and is proposing a modification to two other sections of the regulations (Public Notification and Sanitary Survey rules) to improve clarity. The department is looking for feedback from stakeholders on these proposed modifications. 
In light of the COVID-19 pandemic, the department is using an accelerated schedule for these rule adjustments to reduce the regulatory burden on water systems as quickly as possible while maintaining public health protections.  
The Storage Tank Rule (Regulation 11, Section 28) protects public health and public water systems from potential contamination associated with unprotected storage tanks within the public water system’s drinking water distribution system. The intent of the modifications is to provide additional flexibility to water systems while continuing to protect public health. 
The Backflow Prevention and Cross-Connection Control Rule (Regulation 11, Section 11.39) protects public health from contamination associated with cross-connections and backflow events. The department is proposing three changes that will lessen the burden on water systems while still protecting public health.  
The revisions to the Sanitary Survey Rule (Regulation 11, Section 11.38) and the Backflow Prevention and Public Notification Rule are relatively minor. Unlike other rules, Regulation 11 does not have prescribed language around health effects when a Storage Tank Rule violation occurs. Public notification language for all rules is listed in the Public Notification Rule (Regulation 11, Section 11.33). An additional minor edit is proposed to remove a reference to violations in the Sanitary Survey Rule. Water systems will still be subject to violations during a sanitary survey, but with this change, they will no longer also violate the Sanitary Survey Rule, which was an unintended consequence and causes an undue administrative burden on water systems and the department without further protecting public health.  
These rules can be found in Regulation 11
