R 323.2101 Purpose.  
Rule 2101. (1) These rules are being processed to implement the 1972  
amendments to part 31 of the act which authorized the initiation of a waste or waste  
effluent discharge permit system compatible with the national pollutant discharge  
elimination system (NPDES). The NPDES has been initiated by the federal Congress  
through the enactment of the federal water pollution control act amendments of 1972,  
(33 U.S.C. §1251 et seq.). In general, the rules outline all of the following:  
(a) The procedures by which all persons discharging wastes into the waters of the  
state shall apply for waste or waste effluent discharge permits as required by part 31 of  
the act.  
(b) Exceptions to procedural requirements.  
(c) Public participation procedures and hearings on permit applications.  
(d) Procedures by which permits are issued or denied by the department.  
(e) Appeals procedures.  
(f) Permit conditions and monitoring of waste or wastewater discharges.  
(2) The promulgation of these rules, in association with part 31 of the act,  
provides sufficient authority to the state, upon approval by the United States  
environmental protection agency, to issue permits for waste or wastewater  
discharges under the NPDES pursuant to section 402(b) of the United States Public  
Law 92-500 (33 U.S.C. §1251 et seq.). The department is the state agency designated by  
state law to administer this program.

(h) A concise description of the nature of the public hearing and the issues to be  
heard, with reference to department rules and procedures to be followed.  
History: 1979 AC; 2003 AACS.  
R 323.2133 Permit applications; determinations; issuance; denial.  
Rule 2133. (1) After review of tentative determinations or modifications thereof  
made by the staff of the department pursuant to R 323.2115, any comments on the  
permit application received by the department from the regional administrator  
pursuant to R 323.2112, comments received from the public during the 30-day  
comment period following public notice of the permit application as provided by R  
323.2117, or other applicable recommendations or determinations, and review of the  
public hearing record after a hearing on an application pursuant to R 323.2130, the  
department shall make a final determination on the permit application and may issue  
or deny a state or national permit pursuant to section 3106 of part 31 of the act.  
(2) An appeal to a final determination of the department made pursuant to subrule  
(1) of this rule, or to a condition of a permit issued, or the denial of a permit pursuant to  
Page 20  
part 31 of the act and the rules shall be in accordance with and subject to section  
3113 of part 31 of the act.  
(3) When the department issues a state or national permit to a discharger in  
possession of an order of determination or stipulation of the department issued or  
entered into before April 15, 1973, the state or national permit conditions shall take  
precedence over all conditions of the order of determination or stipulation. If the  
department denies the issuance of a state or national permit to a  
discharger in  
possession of an order of determination or stipulation of the department,  
compliance with the conditions of the order of determination or stipulation is not a  
defense of the discharger's obligation as prescribed by part 31 of the act.  
(4) A national permit issued by the department pursuant to part 31 of the act and  
these rules is a state permit where the permit is issued for waste or wastewater discharges  
into the surface waters of the state. A state permit issued for a waste or wastewater  
discharge into groundwaters or on the ground is not a national permit required pursuant to  
the federal act.

necessary to protect the public health, safety, and welfare.  
(2) An NPDES permit will not be issued to a person proposing any of the  
following discharges into waters subject to regulation under the federal act:  
(a) A discharge containing a radiological, chemical, or biological warfare agent, or  
a high-level radioactive waste.  
(b) A discharge containing a substance which, as determined by the secretary  
of the army acting through the chief of engineers of the United States army corps of

(b) Standards of performance, when promulgated by the administrator of EPA, for  
new sources within the categories defined in section 306 of the federal act.  
(c) If the permit is for a discharge from a publicly owned treatment works, standards  
of performance, pretreatment standards or effluent limitations or prohibitions when  
promulgated by the administrator of EPA for toxic substances, monitoring, and

applicable water quality standards. When a permit contains additional effluent  
limitations based upon applicable water quality standards, the department shall

History: 1979 AC; 2003 AACS.  
R 323.2145 Terms and conditions of permits; schedules of compliance.  
Rule 2145. (1) A person issued a state or national permit by the department pursuant
