thousand people and all community public water systems shall maintain a minimum
chlorine residual of at least two-tenths milligram per liter
(0.2 mg/L) free chlorine, or one milligram per
liter combined chlorine measured at representative points throughout the

water treated with chlorine for disinfection purposes shall maintain the
chlorine residual levels as described in this rule. The director may require
higher residuals as necessary to compensate for pH, temperature, or other
characteristics of the delivered water.
[Comment: Rule
3745-81-72 of the Administrative

using a surface water source. These two requirements are not inconsistent and
failure to comply with either is considered a separate violation with different
consequences. Contact your district office representative if you have questions
or require clarification.]
(2) Noncommunity public water systems serving
a population of at least one thousand people and all community public water
systems shall install and place in operation equipment capable of meeting
disinfection requirements of this rule.

approval of the director, it uses chlorine dioxide as a primary disinfectant in
accordance with the terms of the approval.
[Comment: Plan approval requirements
for a system treating with chlorine dioxide will include minimum chlorine
dioxide residual requirements for the system and any consecutive
systems.]
(4) At
times of actual or threatened outbreak of waterborne disease as defined in rule
3745-81-01 of the Administrative
