455B.173 - DUTIES.

        455B.173  DUTIES.         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 in accordance with the      provisions of this chapter.  The effluent standards may provide for      maintaining the existing quality of the water of the state that is a      navigable water of the United States under the federal Water      Pollution Control Act 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 or chapter 459,      subchapter III, 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.  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.  Cooperate 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.  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.         7.  Adopt a statewide plan for the provision of safe drinking      water under emergency circumstances. All public agencies, as defined      in chapter 28E, shall cooperate 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 coordinated 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 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 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.         11.  Adopt rules for the issuance of a single general permit,      after notice and opportunity for a public hearing.  The single      general permit shall cover numerous facilities to the extent that      they are representative of a class of facilities which can be      identified and conditioned by a single permit.         12.  Adopt, modify, or repeal rules relating to the construction      or operation of animal feeding operations, as provided in sections      relating to animal feeding operations provided in chapter 459,      subchapter III.
