1. The safe drinking water commission created in section 640.105 shall promulgate rules necessary for the implementation, administration and enforcement of sections 640.100 to 640.140 and the federal Safe Drinking Water Act as amended.
2. No standard, rule or regulation or any amendment or repeal thereof shall be adopted except after a public hearing to be held by the commission after at least thirty days' prior notice in the manner prescribed by the rulemaking provisions of chapter 536 and an opportunity given to the public to be heard; the commission may solicit the views, in writing, of persons who may be affected by, knowledgeable about, or interested in proposed rules and regulations, or standards. Any person heard or registered at the hearing, or making written request for notice, shall be given written notice of the action of the commission with respect to the subject thereof. Any rule or portion of a rule, as that term is defined in section 536.010 , that is promulgated to administer and enforce sections 640.100 to 640.140 shall become effective only if the agency has fully complied with all of the requirements of chapter 536 , including but not limited to section 536.028 , if applicable, after June 9, 1998. All rulemaking authority delegated prior to June 9, 1998, is of no force and effect and repealed as of June 9, 1998, however, nothing in this section shall be interpreted to repeal or affect the validity of any rule adopted or promulgated prior to June 9, 1998. If the provisions of section 536.028 apply, the provisions of this section are nonseverable and if any of the powers vested with the general assembly pursuant to section 536.028 to review, to delay the effective date, or to disapprove and annul a rule or portion of a rule are held unconstitutional or invalid, the purported grant of rulemaking authority and any rule so proposed and contained in the order of rulemaking shall be invalid and void, except that nothing in this chapter or chapter 644 shall affect the validity of any rule adopted and promulgated prior to June 9, 1998.
3. The commission shall promulgate rules and regulations for the certification of public water system operators, backflow prevention assembly testers and laboratories conducting tests pursuant to sections 640.100 to 640.140 . Any person seeking to be a certified backflow prevention assembly tester shall satisfactorily complete standard, nationally recognized written and performance examinations designed to ensure that the person is competent to determine if the assembly is functioning within its design specifications. Any such state certification shall satisfy any need for local certification as a backflow prevention assembly tester. However, political subdivisions may set additional testing standards for individuals who are seeking to be certified as backflow prevention assembly testers. Notwithstanding any other provision of law to the contrary, agencies of the state or its political subdivisions shall only require carbonated beverage dispensers to conform to the backflow protection requirements established in the National Sanitation Foundation standard eighteen, and the dispensers shall be so listed by an independent testing laboratory. The commission shall promulgate rules and regulations for collection of samples and analysis of water furnished by municipalities, corporations, companies, state establishments, federal establishments or individuals to the public. The department of natural resources or the department of health and senior services shall, at the request of any supplier, make any analyses or tests required pursuant to the terms of section 192.320 and sections 640.100 to 640.140 . The department shall collect fees to cover the reasonable cost of laboratory services, both within the department of natural resources and the department of health and senior services, laboratory certification and program administration as required by sections 640.100 to 640.140 . The laboratory services and program administration fees pursuant to this subsection shall not exceed two hundred dollars for a supplier supplying less than four thousand one hundred service connections, three hundred dollars for supplying less than seven thousand six hundred service connections, five hundred dollars for supplying seven thousand six hundred or more service connections, and five hundred dollars for testing surface water. Such fees shall be deposited in the safe drinking water fund as specified in section 640.110 . The analysis of all drinking water required by section 192.320 and sections 640.100 to 640.140 shall be made by the department of natural resources laboratories, department of health and senior services laboratories or laboratories certified by the department of natural resources.
4. The department of natural resources shall establish and maintain an inventory of public water supplies and conduct sanitary surveys of public water systems. Such records shall be available for public inspection during regular business hours.
5. (1) For the purpose of complying with federal requirements for maintaining the primacy of state enforcement of the federal Safe Drinking Water Act, the department is hereby directed to request appropriations from the general revenue fund and all other appropriate sources to fund the activities of the public drinking water program and in addition to the fees authorized pursuant to subsection 3 of this section, an annual fee for each customer service connection with a public water system is hereby authorized to be imposed upon all customers of public water systems in this state. Each customer of a public water system shall pay an annual fee for each customer service connection.
(2) The annual fee per customer service connection for unmetered customers and customers with meters not greater than one inch in size shall be based upon the number of service connections in the water system serving that customer, and shall not exceed:
(3) The annual user fee for customers having meters greater than one inch but less than or equal to two inches in size shall not exceed seven dollars and forty-four cents; for customers with meters greater than two inches but less than or equal to four inches in size shall not exceed forty-one dollars and sixteen cents; and for customers with meters greater than four inches in size shall not exceed eighty-two dollars and forty-four cents.
(4) Customers served by multiple connections shall pay an annual user fee based on the above rates for each connection, except that no single facility served by multiple connections shall pay a total of more than five hundred dollars per year.
6. Fees imposed pursuant to subsection 5 of this section shall become effective on August 28, 2006, and shall be collected by the public water system serving the customer beginning September 1, 2006, and continuing until such time that the safe drinking water commission, at its discretion, specifies a different amount under subsection 8 of this section. The commission shall promulgate rules and regulations on the procedures for billing, collection and delinquent payment. Fees collected by a public water system pursuant to subsection 5 of this section and fees established by the commission pursuant to subsection 8 of this section are state fees. The annual fee shall be enumerated separately from all other charges, and shall be collected in monthly, quarterly or annual increments. Such fees shall be transferred to the director of the department of revenue at frequencies not less than quarterly. Two percent of the revenue arising from the fees shall be retained by the public water system for the purpose of reimbursing its expenses for billing and collection of such fees.
7. Imposition and collection of the fees authorized in subsection 5 and fees established by the commission pursuant to subsection 8 of this section shall be suspended on the first day of a calendar quarter if, during the preceding calendar quarter, the federally delegated authority granted to the safe drinking water program within the department of natural resources to administer the Safe Drinking Water Act, 42 U.S.C. Section 300g-2, is withdrawn. The fee shall not be reinstated until the first day of the calendar quarter following the quarter during which such delegated authority is reinstated.
* 8. Notwithstanding any statutory fee amounts or maximums to the contrary, the department of natural resources may conduct a comprehensive review and propose changes to the fee structure set forth in this section. The comprehensive review shall include stakeholder meetings in order to solicit stakeholder input from public and private water suppliers, and any other interested parties. Upon completion of the comprehensive review, the department shall submit a proposed fee structure with stakeholder agreement to the safe drinking water commission. The commission shall review such recommendations at a forthcoming regular or special meeting, but shall not vote on the fee structure until a subsequent meeting. If the commission approves, by vote of two-thirds majority or six of nine commissioners, the fee structure recommendations, the commission shall authorize the department to file a notice of proposed rulemaking containing the recommended fee structure, and after considering public comments may authorize the department to file the final order of rulemaking for such rule with the joint committee on administrative rules pursuant to sections 536.021 and 536.024 no later than December first of the same year. If such rules are not disapproved by the general assembly in the manner set out below, they shall take effect on January first of the following calendar year, at which point the existing fee structure shall expire. Any regulation promulgated under this subsection shall be deemed to be beyond the scope and authority provided in this subsection, or detrimental to permit applicants, if the general assembly within the first sixty calendar days of the regular session immediately following the filing of such regulation disapproves the regulation by concurrent resolution. If the general assembly so disapproves any regulation filed under this subsection, the department and the commission shall not implement the proposed fee structure and shall continue to use the previous fee structure. The authority of the commission to further revise the fee structure as provided by this subsection shall expire on August 28, 2030. If the commission's authority to revise the fee structure as provided by this subsection expires, the fee structure in place at the time of expiration shall remain in place.
