A PWS owner may use point of use (POU) treatment to comply with certain maximum contaminant levels (MCL) or treatment techniques when the following conditions are met: i. A program for long-term operation, maintenance, and monitoring of the POU treatment system is approved by the Department, pursuant to Subsection 450.02.c.ii. The PWS owner or a vendor of POU treatment devices under contract with the PWS must own, control, and maintain the POU treatment system to ensure proper operation and maintenance and compliance with the MCL or treatment technique.iii. Each POU treatment device is equipped with a mechanical warning mechanism to ensure customers are automatically notified of operational problems.iv. Each POU treatment device must be certified by an accredited American National Standards Institute (ANSI) certification body to meet applicable ANSI/National Sanitation Foundation (NSF) Standards.v. POU treatment devices will not be used to comply with an MCL or treatment technique requirement for a microbial contaminant or an indicator of a microbial contaminant. Community PWSs may not use POU treatment devices to comply with a nitrate or nitrite MCL.b. The Department will waive the plan and specification requirements of Section 504 relating to material modifications for the following systems only to the extent that the material modification is limited to the installation or use of a POU treatment device(s):i. Community PWSs serving two hundred (200) or fewer service connections.ii. Non-transient non-community PWSs;iii. Transient non-community PWSs; oriv. Community PWSs serving more than two hundred (200) service connections if approved by the Department through the waiver process outlined in Subsection 005.02.c. Prior to installation, the PWS owner must submit the following documentation for approval to the Department. i. Water system information: (1) PWS name and identification number;(2) Total number of service connections;(3) Demonstration that all POU treatment devices are owned, controlled, and maintained by the PWS owner or by a vendor of POU treatment devices under contract with the PWS owner;(4) Documentation that a customer at each service connection has agreed to installation and use of a POU treatment device and has granted access for installation, maintenance, and sampling;(5) A statement of recognition that failure to maintain compliance with the MCL, or the failure to operate and maintain compliance with a POU treatment system as approved by the Department, may necessitate installation of centralized treatment; and(6) Documentation that the PWS is current with certified operator requirements pursuant to Section 554.ii. POU device information:(1) Type of POU treatment device;(2) Manufacturer, model number, and manufacturer's specifications;(3) Contaminant to be treated and documentation that the POU is certified and is of sufficient design and capacity for removal of the contaminant;(4) Documentation that the PWS's water chemistry is compatible with the POU;(5) Type and function of the mechanical warning (performance indicator);(6) Certification verification for ANSI/NSF;(7) Documentation describing how other drinking water dispensing units, such as hot water dispensers and refrigerators, soda machines, water fountains, and other similar units will be provided with treated water and how the water will be transported to that unit with non-reactive piping or tubing. Non-transient non-community and transient non-community PWSs must demonstrate that the POU treatment devices are located in areas adequate to protect public health and in sufficient quantity to serve the system's users;(8) Installer qualifications; and(9) Proposed date for completing installation(s).iii. POU operation, maintenance, and sampling plan that includes documentation on how the PWS owner will:(1) Address any non-compliance with Subsection 450.02.c.i.(4);(2) Ensure real estate disclosures for the POU treatment systems;(3) Deliver ongoing education and outreach to customers, including renters, regarding POU treatment and health effects of the contaminant(s) of concern;(4) Address and perform on-going maintenance activities, including frequency of treatment media replacements and treatment device replacements, periodic verification that the mechanical warning device is functional, schedule of planned maintenance activities, a plan to address unscheduled maintenance problems, and a plan and method of waste disposal; and(5) Collect samples from the location of all service connections and demonstrating that all POU treatment devices will be sampled for compliance with the treated contaminant(s) during every compliance period or other frequency designated by the Department.d. Within thirty (30) days of installing the approved POU treatment system, the PWS owner must:i. Notify the Department in writing that the POU treatment system was installed as approved by the Department.ii. Submit samples from each POU treatment device to a certified laboratory for the contaminant(s) being treated to demonstrate initial compliance with the MCL.e. The PWS owner or operator must maintain records for a POU treatment system. Records must be submitted to the Department at a frequency and in a format specified by the Department. Records to maintain include:i. Requirements of Subsection 450.02.c.;ii. All sampling performed on the POU treatment devices;iii. Maintenance logs and schedules;iv. Log of installed units; andv. Contracts, lease agreements, or other legal documents with vendors and consumers.03.Use of Bottled Water. 40 CFR 141.101 is incorporated by reference.Idaho Admin. Code r. 58.01.08.450
