Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Prior to installing POUs, and as part of its permit application to use POU in
				  lieu of centralized treatment, a public water system shall submit to the State
				  Board a POU Treatment Strategy sufficient to reliably reduce levels of the
				  contaminants listed in section
				  64418(a) and
				  comply with drinking water standards. The POU Treatment Strategy shall include
				  the following:
(1) A description of the
				  compliance issues for which POUs are being proposed to address and how the use
				  of POUs will achieve compliance;
(2) A description of how the public water
				  system will determine the type, number, and location of POUs to ensure a
				  sufficient number of devices are installed for human consumption at each
				  building and each dwelling unit connected to the public water system;
(3) The public water system's authority to
				  require customers to accept POUs in lieu of centralized treatment and to take
				  an action, such as discontinuing service, if a customer fails to accept
				  POUs;
(4) The basis for the POU
				  selection(s);
(5) The
				  qualifications and identification of the person(s) responsible for POU
				  installation, operation, maintenance, and water quality sampling and
				  analyses;
(6) A Customer Education
				  Program that includes information about the POU, how the devices work, required
				  maintenance and monitoring, and the need for the person(s) responsible for the
				  POU, as defined in paragraph (a)(5) of this section, to have access to the
				  device to perform required maintenance and monitoring. The Customer Education
				  Program shall be designed to reach all customers and shall be implemented prior
				  to and following installation of POUs;
(7) The authority, ordinances, and/or access
				  agreements adequate to allow the public water system's representatives access
				  to customers' premises for POU installation, maintenance, and water quality
				  monitoring, as well as the surveys necessary to meet paragraph
				  (a)(2);
(8) Identification of
				  applicable local regulatory requirements;
(9) A Consumer Notification Protocol designed
				  to timely inform consumers, in the appropriate language(s), in the event that
				  an installed POU fails to produce water that meets drinking water standards.
				  The Consumer Notification Protocol shall include:
(A) an example of a notice that includes the
				  requirements of Article 18 of this Title, and
(B) a plan for providing an alternative water
				  supply that meets drinking water standards, consistent with section
				  64551.100 of this Title, in a
				  quantity sufficient for daily household ingestion needs, to customers served by
				  each installed POU not meeting drinking water standards. An alternative water
				  supply shall be provided according to the following timeline;
1. as soon as possible, but no later than 24
				  hours following the receipt of results of confirmation samples indicating an
				  MCL exceedance for nitrate, nitrite, nitrate plus nitrite, or perchlorate,
				  or
2. as soon as possible, but no
				  later than 7 days following the receipt of results of confirmation samples
				  indicating an MCL exceedance for contaminants other than nitrate, nitrite,
				  nitrate plus nitrite, or perchlorate;
(10) A Customer Notification Protocol for
				  routine notifications that includes examples of notices, to be provided no less
				  frequently than quarterly, in the appropriate language(s) to inform each
				  customer and consumer:
(A) that only the taps
				  for which POUs are installed provide water meeting drinking water standards,
				  and
(B) regarding the mechanical
				  warning or shut-off mechanism required pursuant to paragraph 64418.2(a)(5),
				  including a telephone number that connects the customer or consumer to water
				  system personnel or recording system that shall be accessible by water system
				  personnel 24 hours a day, seven days a week, for the purpose of providing the
				  customer or consumer a reliable means of notifying personnel when the
				  mechanical warning or shut-off mechanism is activated;
(11) The proposed schedules for:

				  information pursuant to section
				  64418.6,
