TO BE RESCINDED

 

3745-83-01                  Operational requirements.

 

 

 

(A)   Except as otherwise noted, the definitions in rule 3745-81-01 of the Administrative Code shall apply to this chapter.

 

(B)  Disinfection.

 

(1)    For purposes of this rule of the Administrative Code, "major noncommunity public water system" means a noncommunity public water system designated by the director for which he deems it advisable, because of the relatively large number of people who drink or may drink water from the system, that the water be disinfected in the same manner as for a community public water system.

 

(2)    Unless exempted under other provisions of this rule, each community public water system and each major noncommunity public water system shall maintain a minimum chlorine residual of at least two-tenths milligram per liter free chlorine, or one milligram per liter combined chlorine measured at representative points throughout the distribution system. The director may by order require higher residuals as necessary to compensate for pH, temperature, or other characteristics of the delivered water. Chlorine concentrations shall be analyzed in accordance with paragraph (C) of rule 3745-81-27 of the Administrative Code.

 

(3)    A system is exempt from paragraph (B)(2) of this rule if it meets all the following conditions:

 

(a)   The system obtains all its water from a ground water source which has, in the judgment of the director, been properly developed, constructed, and adequately protected; or from a system to which paragraph (B)(2) of this rule applies;

 

(b)   The distribution system serving the water system, in the judgement of the director, has been properly constructed and maintained and is protected by an effective cross-connection program;

 

(c)    The system, in the judgment of the director, has a satisfactory history of bacteriological monitoring indicating no contamination;

 

(d)     The director has certified in writing that conditions of paragraphs (B)(3)(a), (B)(3)(b), and (B)(3)(c) of this rule have been met.

 

 

 

(4)   A system is exempt from paragraph (B)(2) of this rule if, with written approval of the director, it uses chlorine dioxide as a primary or supplementary disinfectant in accordance with the terms of the approval.

(5)   Each water system subject to paragraph (B)(2) of this rule and not exempt under paragraph (B)(3) of this rule shall install and place in operation equipment capable of meeting disinfection requirements of this rule.

(6)   Notwithstanding the MRDL for total residual chlorine in paragraph (C) of rule 3745-81-10 of the Administrative Code, at times of actual or threatened outbreak of waterborne disease, each system subject to paragraph (B)(2) of this rule that may be affected by such outbreak shall maintain a minimum chlorine residual of at least one milligram per liter free chlorine, or six milligrams per liter combined chlorine measured at representative points throughout the distribution system, despite possible resulting tastes or odors in the delivered water.

(7)    Finished water storage facilities, as defined in paragraph (E)(1) of this rule, serving community water systems or major non-community water systems shall be adequately disinfected in accordance with "American Water Works Association Standard C652-02 Disinfection of Water-Storage Facilities (2002)" before being placed in service and before being returned to service after repairs. A reservoir shall be considered adequately disinfected when analyses of at least two consecutive samples taken at twenty-four hour intervals are total coliform-negative. The consecutive samples taken in order to determine compliance with this paragraph shall be analyzed in accordance with paragraph (D) of rule 3745-81-27 of the Administrative Code. The standard sample used shall contain one hundred milliliters.

(8)   All new, cleaned, or repaired water mains serving community water systems or major noncommunity water systems shall be disinfected in accordance with "American Water Works Association Standard C651-99 Disinfecting Water Mains (1999)." Samples taken in order to determine compliance with this paragraph shall each contain one hundred milliliters and shall be analyzed in accordance with paragraph (D) of rule 3745-81-27 of the Administrative Code.

(a)    A new or cleaned water main shall be considered adequately disinfected when analyses of at least two consecutive samples taken at twenty-four hour intervals are total coliform-negative.

(b)    Repaired water mains shall be considered adequately disinfected when

analyses of samples taken in accordance with "American Water Works Association Standard C651-99 Disinfecting Water Mains (1999), Section 4.7.5" are total coliform-negative.

(C)   Approval of chemicals. All chemicals, substances, and materials added to or brought in contact with water in or intended to be used in a public water system or used for the purpose of treating, conditioning, altering, or modifying the characteristics of such water shall be shown by either the manufacturer, distributor, or purveyor to be non-toxic and harmless to humans when used in accordance with the formulation and concentration as specified by the manufacturer, and shall conform with the "American National Standards Institute/National Sanitation Foundation" (ANSI/NSF) standard 60 Drinking Water Treatment Chemicals - Health Effects (2001 and previous), or standard 61 Drinking Water System Components - Health Effects (2003 and previous). Any organization certified by the "American National Standards Institute" may certify in writing that a product conforms with these standards.

(D)   Minimum pressure. Community water systems shall maintain a minimum pressure of twenty pounds per square inch gage at ground level at all points in the distribution system under all conditions of flow other than conditions caused by line breaks, extreme fire flows, or other extraordinary circumstances.

(E)  Finished water storage facilities

(1)   "Finished water storage facility" means a tank, reservoir, or other facility used to store water that will undergo no further treatment except residual disinfection.

(2)   A public water system shall provide a cover on all finished storage facilities so they are not open to the atmosphere.

(F)   Reports.

(1)   Community water systems.

(a)   In addition to any other reporting requirement of Chapter 3745-81 of the Administrative Code, the operator of a community water system shall prepare an operation report for each month of operation on forms provided by the director. The director may require that the report include the following:

(i)   General operation data;

(ii)     A  summary  of  samples  analyzed,  including  distribution  system sampling and chlorine residual sampling;

(iii)   Information on daily water treatment and system pumpage;

(iv)   Information on chemical application;

(v)   Analysis of general parameters relating to the quality of the treated drinking water;

(vi)   Source water levels;

(vii)   Changes in personnel in responsible charge;

(viii)    Such other information as may be necessary or desirable for the director to carry out his duties under Chapter 6109. of the Revised Code.

(b)      The operation report shall be submitted to the district office with jurisdiction no later than the tenth of the month following the month for which the report was prepared.

(c)      The operator shall report significant interruptions of service or of chlorination immediately by telephone to the district office with jurisdiction.

(2)   Noncommunity water systems.

(a)    The operator of a public water system other than a community public water system shall prepare and file an operation report at a frequency determined in writing by the director. The reports shall be on forms provided by the director and shall contain such information as may be necessary for the director to carry out his duties under Chapter 6109. of the Revised Code.

(b)      The operation report shall be submitted to the district office with jurisdiction no later than the tenth of the month following the end of the period for which the report was prepared.
