Current through Register Vol. 47, No. 3, July 24, 2024
(1)
Emergency actions regarding water supplies.
When, in the
				  opinion of the director, an actual or imminent hazard exists, the supplier of
				  water shall comply with the directives or orders of the director necessary to
				  eliminate or minimize that hazard.
(2)
Prohibition on the use of lead
				  pipes, solder and flux.
Any pipe, solder or flux which is used in the
				  installation or repair of any public water supply system or any plumbing in a
				  residential or nonresidential facility providing water for human consumption
				  which is connected to a public water supply system shall be lead-free as
				  defined in 567-402. (455B). This action
				  shall not apply to leaded joints necessary for the repair of cast iron
				  pipe.
(3)
Use of
				  noncentralized treatment devices.
a.
Community PWS.
Community public water systems shall not use
				  bottled water, point-of-use (POU) or point-of-entry (POE) devices to achieve
				  permanent compliance with a maximum contaminant level, action level, or
				  treatment technique requirement in 567-Chapters 41 and 43.
b.
Noncommunity PWS.
Noncommunity public water supply systems may be allowed by the department to
				  use point-of-use devices to achieve MCL compliance provided the contaminant
				  does not pose an imminent threat to health (such as bacteria) nor place a
				  sensitive population at risk (such as infants for nitrate or
				  nitrite).
c.
Reduced
				  monitoring requirements.
Bottled water, point-of-use, or
				  point-of-entry devices cannot be used to avoid the monitoring requirements of
				  567-Chapters 41 and 43, but the department may allow reduced monitoring
				  requirements in specific instances.
d.
Bottled water
				  requirements.
The department may require a public water system
				  exceeding a maximum contaminant level, action level, or treatment technique
				  requirement specified in 567-Chapters 41 and 43 to use bottled water as a
				  condition of an interim compliance schedule or as a temporary measure to avoid
				  an unreasonable risk to health. Any bottled water must, at a minimum, meet the
				  federal Food and Drug Administration bottled water standards, listed in the
				  Code of Federal Regulations, Title 21, Chapter 165.110. The system must meet
				  the following requirements:
(1) Monitoring
				  program. Submit for approval to the department a monitoring program for bottled
				  water. The monitoring program must provide reasonable assurances that the
				  bottled water complies with all maximum contaminant levels, action levels, or
				  treatment technique requirements in 567-Chapters 41 and 43. The public water
				  system must monitor a representative sample of bottled water for all
				  contaminants regulated under 567-Chapters 41 and 43 the first quarter that it
				  supplies the bottled water to the public, and annually thereafter. Results of
				  the monitoring program shall be provided to the department annually. If the
				  bottled water is from a community public water system that currently meets all
				  of the federal Safe Drinking Water Act requirements, the monitoring
				  requirements of this subparagraph shall be waived by the department. The
				  specific supplier of the bottled water must be identified in order for the
				  department to waive the monitoring requirements.
(2) Certification requirements. The public
				  water system must receive a certification from the bottled water company that
				  the bottled water supplied has been taken from an "approved source"; the
				  bottled water company has conducted monitoring in accordance with
				  43.1(3)"Z>"(1); and the bottled water meets MCLs, action levels, or
				  treatment technique requirements as set out in 567-Chapters 41 and 43. The
				  public water system shall provide the certification to the department the first
				  quarter after it supplies bottled water and annually thereafter.
(3) Provision of bottled water to consumers.
				  The public water supply system is fully responsible for the provision of
				  sufficient quantities of bottled water to every person supplied by the public
				  water system via door-to-door bottled water delivery.
