The commission shall:
1. Develop comprehensive plans and programs for the prevention, control and abatement of water pollution.
2. Establish, modify, or repeal water quality standards, pretreatment standards and effluent standards. The effluent standards may provide for maintaining the existing quality of the water of the state where the quality thereof exceeds the requirements of the water quality standards.
If the federal environmental protection agency has promulgated an effluent standard or pretreatment standard pursuant to section 301, 306 or 307 of the federal Water Pollution Control Act, a pretreatment or effluent standard adopted pursuant to this section shall not be more stringent than the federal effluent or pretreatment standard for such source. This section may not preclude the establishment of a more restrictive effluent limitation in the permit for a particular point source if the more restrictive effluent limitation is necessary to meet water quality standards, the establishment of an effluent standard for a source or class of sources for which the federal environmental protection agency has not promulgated standards pursuant to section 301, 306 or 307 of the federal Water Pollution Control Act. Except as required by federal law or regulation, the commission shall not adopt an effluent standard more stringent with respect to any pollutant than is necessary to reduce the concentration of that pollutant in the effluent to the level due to natural causes, including the mineral and chemical characteristics of the land, existing in the water of the state to which the effluent is discharged. Notwithstanding any other provision of this part of this division, any new source, the construction of which was commenced after October 18, 1972, and which was constructed as to meet all applicable standards of performance for the new source or any more stringent effluent limitation required to meet water quality standards, shall not be subject to any more stringent effluent limitations during a ten-year period beginning on the date of completion of construction or during the period of depreciation or amortization of the pollution control equipment for the facility for the purposes of section 167 and 169 or both sections of the Internal Revenue Code, whichever period ends first.
3. Establish, modify or repeal rules relating to the location, construction, operation, and maintenance of disposal systems and public water supply systems and specifying the conditions, including the viability of a system pursuant to section 455B.174, under which the director shall issue, revoke, suspend, modify, or deny permits for the operation, installation, construction, addition to, or modification of any disposal system or public water supply system, or for the discharge of any pollutant or for the disposal of water wastes resulting from poultry and livestock operations. The rules specifying the conditions under which the director shall issue permits for the construction of an electric power generating facility subject to chapter 476A shall provide for issuing a conditional permit upon the submission of engineering descriptions, flow diagrams and schematics that qualitatively and quantitatively identify effluent streams and alternative disposal systems that will provide compliance with effluent standards or limitations.
No rules shall be adopted which regulate the hiring or firing of operators of disposal systems or public water supply systems except rules which regulate the certification of operators as to their technical competency.
A publicly owned treatment works whose discharge meets the final effluent limitations which were contained in its discharge permit on the date that construction of the publicly owned treatment works was approved by the department shall not be required to meet more stringent effluent limitations for a period of ten years from the date the construction was completed and accepted but not longer than twelve years from the date that construction was approved by the department.
4. Co-operate with other state or interstate water pollution control agencies in establishing standards, objectives, or criteria for the quality of interstate waters originating or flowing through this state.
5. Establish, modify or repeal rules relating to drinking water standards for public water supply systems. Such standards shall specify maximum contaminant levels or treatment techniques necessary to protect the public health and welfare. The drinking water standards must assure compliance with federal drinking water standards adopted pursuant to the federal Safe Drinking Water Act.
6. a. Adopt rules relating to inspection, monitoring, recordkeeping, and reporting requirements for the owner or operator of any public water supply or any disposal system or of any source which is an industrial user of a publicly or privately owned disposal system.
b. Adopt rules which require each public water system regulated under chapter 455B to test the source water of that supply for the presence of synthetic organic chemicals and pesticides every three years. The rules shall enumerate the synthetic organic chemicals and pesticides, but not more than ten of each, for which the samples are to be tested; shall specify the approved analytical methods for conducting the analysis of water samples; and shall require the reporting of the analytical test results to the department. Priority for testing in the first year shall be those public water supplies for which none of the specified contaminants have been analyzed within the past five years. All of the laboratory analysis and data management shall be conducted by the center for health effects of environmental contamination. Sample collection shall be conducted using a standard sampling protocol by personnel within the department and the center for health effects of environmental contamination in conjunction with other ongoing field activities. Samples from private wells and samples from privately owned public water supplies shall be allowed to undergo the same analysis. The cost for the analysis provided for samples from private wells and privately owned public water supplies shall not exceed one hundred ninety-five dollars for the first year of testing. The department shall submit a report to the general assembly, by September 1 of each year, of the findings of the tests and the conclusions which may be drawn from the tests.
7. Adopt a statewide plan for the provision of safe drinking water under emergency circumstances. All public agencies, as defined in chapter 28E, shall co-operate in the development and implementation of the plan. The plan shall detail the manner in which the various state and local agencies shall participate in the response to an emergency. The department may enter into any agreement, subject to approval of the commission, with any state agency or unit of local government or with the federal government which may be necessary to establish the role of such agencies in regard to the plan. This plan shall be co-ordinated with disaster emergency plans.
8. Formulate and adopt specific and detailed statewide standards pursuant to chapter 17A for review of plans and specifications and the construction of sewer systems and water supply distribution systems and extensions to such systems not later than October 1, 1977. The standards shall be based on criteria contained in the "Recommended Standards for Sewage Works" and "Recommended Standards for Water Works" (Ten States Standards) as adopted by the Great Lakes-Upper Mississippi River board of state sanitary engineers, design manuals published by the department, applicable federal guidelines and standards, standard textbooks, current technical literature and applicable safety standards. The material standards for polyvinyl chloride pipe shall not exceed the specifications for polyvinyl chloride pipe in designations D-1784-69, D-2241-73, D-2564-76, D-2672-76, D-3036-73 and D-3139-73 of the American society of testing and material. The rules adopted which directly pertain to the construction of sewer systems and water supply distribution systems and the review of plans and specifications for such construction shall be known respectively as the Iowa Standards for Sewer Systems and the Iowa Standards for Water Supply Distribution Systems and shall be applicable in each governmental subdivision of the state. Exceptions shall be made to the standards so formulated only upon special request to and receipt of permission from the department. The department shall publish the standards and make copies of such standards available to governmental subdivisions and to the public.
9. Adopt, modify or repeal rules relating to the construction and reconstruction of water wells, the proper abandonment of wells, and the registration or certification of water well contractors. The rules shall include those necessary to protect the public health and welfare, and to protect the waters of the state. The rules may include, but are not limited to, establishing fees for registration or certification of water well contractors, requiring the submission of well driller's logs, formation samples or well cuttings, water samples, information on test pumping and requiring inspections. Fees shall be based upon the reasonable cost of conducting the water well contractor registration or certification program.
10. Adopt, modify, or repeal rules re- lating to the awarding of grants to counties for the purpose of carrying out responsibilities pursuant to section 455B.172 relative to private water supplies and private sewage disposal facilities.
11. Adopt, modify, or repeal rules relating to the business plan which disposal systems and public water supply systems must file with the department pursuant to section 455B.174, and adopt, modify, or repeal rules establishing a methodology and timetable by which nonviable systems shall take action to become viable or make alternative arrangements in providing treatment or water supply services.
