Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 60 - Safe Drinking Water Commission › Chapter 14 - Operator Certification › Section 10 CSR 60-14.010 - Classification of Public Water Systems and System Requirements

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The amendment will revise the classification
				  levels of public water system treatment and distribution systems for the
				  purpose of determining the certification level required for the chief operator
				  and other certified personnel.
(1) Applicability. This rule applies to all
				community and nontransient noncommunity public water systems and those
				transient noncommunity public water systems that use surface water or
				groundwater under the direct influence of surface water. Therefore, where the
				term "public water system" is used in this rule, it is understood to refer only
				to these types of systems.
(2)
				Definitions.
(A) Available. Based on system
				size, complexity, and source water quality, a certified operator must be
				on-site or able to be contacted promptly (i.e., reasonably accessible) as
				needed to initiate appropriate action in a timely manner.
(B) Certified operator. Any individual
				holding a valid water treatment or water distribution certificate of any level
				issued by the department.
(C) Chief
				operator. A certified operator designated by the owner of the public water
				system to have overall responsibility for the day-to-day process control/system
				integrity decisions regarding supervisory and operational activities that will
				directly impact the quality and quantity of drinking water. This individual
				must possess a certificate at the level of or higher than the classification of
				the treatment facility or distribution system for which he or she is
				responsible.
(D) Operator in
				responsible charge. An individual who performs the duties of a chief
				operator.
(E) Operate. To make or
				act upon process control/system integrity decisions regarding a water treatment
				facility or distribution system.
(F) Process control/system integrity
				decisions. Day-to-day decisions that maintain or cause changes in the chemical,
				biological, physical or radiological quality of the drinking water. These
				decisions primarily reflect independent, individual judgement which when made
				incorrectly have the potential to place the public health at risk or place the
				soundness of the water system or its ability to provide a safe, adequate and
				continuous supply of water at risk. These decisions are not referring to system
				design or modifications for which the department requires design or approval by
				a professional engineer.
(G)
				Treatment facility. Any place(s) where a community water system or nontransient
				noncommunity water system alters the physical or chemical characteristics of
				the drinking water. Chlorination may be considered a function of a distribution
				system.
(H) Distribution system.
				Any combination of pipes, tanks, pumps, etc. which delivers water from the
				source(s) and/or treatment facility(ies) to the consumer.
