NR 809.837 Consumer confidence report delivery and recordkeeping. NR 809.837(1)(1)
General delivery requirements. Except as provided in sub.
(7), water suppliers for each community water system shall mail or otherwise directly deliver one copy of the report to each customer. Electronic delivery of the report is allowed if the water supplier of a community water system uses paper or electronic communication containing uniform resource locator (URL) information providing a direct link to the report and if the communication prominently displays the URL and a notice explaining the nature of the link. The electronic link shall take the customer to the entire report without directing the customer to another internet page.
NR 809.837(2)
(2)
Delivery to consumers that are not billed. The water supplier shall make a good faith effort to reach consumers who do not get water bills, using means recommended by the department. EPA expects that an adequate good faith effort will be tailored to the consumers who are served by the public water system but are not bill-paying customers, such as renters or workers. A good faith effort to reach consumers would include a mix of methods appropriate to the particular public water system such as: Posting the reports on the Internet; mailing to postal patrons in metropolitan areas; advertising the availability of the report in the news media; publication in a local newspaper; posting in public places such as cafeterias or lunch rooms of public buildings; delivery of multiple copies for distribution by single-biller customers such as apartment buildings or large private employers; delivery to community organizations.
NR 809.837(3)
(3)
Delivery to the department. No later than the date the public water system is required to distribute the report to its customers, the water supplier for each community water system shall also mail a copy of the report to the department, along with a certification that the report has been distributed to customers, and that the information is correct and consistent with the compliance monitoring data previously submitted to the department.
NR 809.837(4)
(4)
Delivery to other agencies. No later than the date the public water system is required to distribute the report to its customers, the water supplier for each community water system shall deliver the report to any other agency or clearinghouse identified by the department.
