R 323.2206 Applicant responsibilities; compliance schedule; standard for municipal  
wastewater treatment system; renewal, reissuance, or modification of permit  
establishing effluent or groundwater limitations.  
Rule 2206. (1) It is the responsibility of the applicant to provide the information described  
in these rules as required or necessary for the department to make a decision.  
(2) Failure to comply with the terms and conditions of an authorization to discharge  
granted under this part, failure to comply with an applicable monitoring or reporting  
requirement, or discharging in excess of an applicable standard is a violation of this part.  
(3) The department shall compile and keep on file a central quarterly listing of all  
dischargers who have exceeded a standard set by these rules for the concentration of a  
substance in the effluent or groundwater or who have failed to submit a complete  
compliance monitoring report as required by a permit. The listing shall identify the  
discharger and the substance or substances that exceeded the effluent or groundwater  
standard. In addition, the department shall also maintain records describing the actions  
taken by the department and the discharger in response to an effluent or groundwater  
standard being exceeded and the time necessary in each case to return the concentration of  
the substance in the effluent or groundwater to below the standard set by these rules. The  
listings and records are subject to Act No. 442 of the Public Acts of 1976, as amended,  
being §15.231 et seq. of the Michigan Compiled Laws, and known as the freedom of  
information act.  
(4) If necessary to secure compliance with this part by a person discharging to  
groundwater on the effective date of these rules without causing impracticable disruption  
of the activity causing the discharge, the department may establish a schedule in a permit  
under which the discharger shall come into compliance with this part during the term of  
the permit. The department may not authorize a discharge under this subrule unless the  
discharge meets the requirements of R 323.2204(2)(a).  
(5) A wastewater treatment system shall not be subject to a more stringent standard than  
that contained in a permit during the depreciation or amortization of the facility for the  
purposes of section 167 or 169, or both, of the tax reform act of 1986, as amended, 26  
U.S.C. §167 or §169, or both, but not longer than 10 years from the date of permit issuance,  
if the treatment system meets all of the following conditions:  
(a) The discharge is appropriately characterized as described in R 323.2220.  
(b) The treatment system is constructed after the effective date of these rules to meet all  
applicable standards described in R 323.2222.  
(c) The discharge is permitted under R 323.2218.  
(d) The discharge does not create a facility as defined in part 201 at any time during the  
term described in this subrule.  
Page 7  
(6) In the case of effluent or groundwater limitations established under a permit issued by  
the department before the effective date of these rules, a permit may not be reissued or  
modified on the basis of a standard described in R 323.2222 that is less stringent than the  
comparable effluent or groundwater limitation in the previous permit. This restriction does  
not apply to a standard developed under R 323.2222(2)(c). The department may grant an  
exception to this subrule, taking into account the state?s paramount concern for the  
protection of its natural resources or the public trust in those resources from pollution,  
impairment, or destruction, if 1 of the following provisions applies:  
(a) A less stringent standard is necessary because of events over which the discharger  
does not have control and for which there is no available remedy.  
(b) The discharger has installed the treatment facilities required to meet the limitation in  
the previous permit and has properly operated and maintained the facilities, but has been  
unable to achieve the previous limitation. In this situation, the reissued or modified permit  
shall contain a standard that reflects the level of pollutant control actually achieved if the  
standard is not less stringent than would otherwise be required by R 323.2222.  
(c) The discharger demonstrates, and the department finds, that the limitation in the prior  
permit is not economically achievable. In making this demonstration, the discharger shall  
demonstrate that the cost of maintaining treatment capability and controls in place is not a  
feasible and prudent alternative to the use of the standard specified in R 323.2222. The  
department shall specifically solicit public comments on the demonstration in the public  
notice accompanying the proposed permit reissuance or modification.  
(d) The standard specified in R 323.2222 is less stringent than the prior limitation because  
the risk posed by the substance has been reevaluated based on new scientific information.

if it occurred in the groundwater, a facility as defined by part 201 would exist.  
(ii) If the substance is detected in groundwater, then the discharger shall take initial  
response as required by R 323.2228. Measurement for this purpose shall be according to R  
323.2224, except that R 323.2224(2) shall not apply.  
(d) If the substance is an organic parameter for which there is no standardized or EPA-  
approved analytical method, then the discharge shall be controlled by limiting the volume  
of the substance used by the discharger. The volume shall result in a discharge that has a  
concentration of the substance, as determined by use of a mass balance equation, which  
does not exceed the concentration at which a facility as defined by part 201 would be  
created.  
(e) If there is insufficient information concerning the substance to determine the criteria  
described in subdivision (a), (c), or (d) of this subrule, then the substance shall not be  
discharged, except pursuant to subrule (7) of this rule.  
(6) If the standard determined under subrule (5) of this rule is below the detection limit  
as determined by the department for this part, then the department may take 1 of the  
following actions:  
(a) Deny the application if the risks associated with the inability to detect the substance  
at concentrations below the detection limit are determined by the department to be  
unacceptable.  
(b) Require the discharger to demonstrate that the concentration in the discharge is not  
above, and cannot be above, the standard by estimating the concentration of the substance  
in the discharge as described in R 323.2220(5) or by monitoring the internal processes for  
the substance.  
(c) Establish a standard in the permit at the detection limit as determined by the  
department for the purposes of compliance with this subrule.  
(7) The department may approve a standard different from the standards established in  
subrules (2) to (6) of this rule under any of the following circumstances:

Page 33  
(iii) Except as provided in paragraph (v) of this subdivision, the distance between the  
point of discharge and the point of venting to surface water is less than 1,000 feet.  
(iv) Deed restrictions, on a form approved by the department, preventing the withdrawal  
and use of the groundwater for all protected uses that would be impacted by the discharge  
have been recorded with the register of deeds for all property, including the property of the  
discharger, downgradient from the discharge to the point of venting.  
(v) A discharge otherwise meeting the conditions in this subrule that occurs at more than  
1,000 feet from the point of venting to surface water may be authorized if the discharger  
owns all property between the point of discharge and the point of venting and if the  
department determines that alternative methods of wastewater disposal are not  
economically or technically feasible, that a prudent alternative does not exist, and that the  
discharge promotes the public health, safety, and welfare in light of the state's paramount  
concern for the protection of its natural resources.  
(c) The department may issue a permit that has a limit that is higher than the standard  
established by subrules (2) to (6) of this rule, if all other conditions of this part are met and  
if the applicant demonstrates either of the following:  
(i) Background groundwater quality exceeds the standard established in this rule for any  
substance and the discharge does not increase the concentration of the substance in the  
groundwater. A permit issued under this subdivision may limit a substance in the discharge  
in order to reflect changes in background groundwater quality or municipal water supply  
quality.  
(ii) The source of the water is a municipal water supply delivered in compliance with Act  
No. 399 of the Public Acts of 1976, as amended, being R 325.1001 et seq. of the Michigan  
Compiled Laws, and known as the safe drinking water act, the water exceeds the standard  
established in this rule for the substance, and the discharge does not increase the  
concentration of the substance in the groundwater above the concentration of the municipal  
water supply. A permit issued under this subdivision may limit a substance in the discharge  
in order to reflect changes in background groundwater quality or municipal water supply  
quality.  
(d) If an applicant demonstrates that existing groundwater quality exceeds the standard  
established in this rule for total inorganic nitrogen, then a permit may be issued by the  
department that has a higher limit than the standard established in this rule if the limit is  
not more than the state drinking water standard established under Act No. 399 of the Public  
Acts of 1976, as amended, being R 325.1001 et seq. of the Michigan Compiled Laws, and  
known as the safe drinking water act, the concentration of total inorganic nitrogen in the  
discharge does not increase the concentration of total inorganic nitrogen in the  
groundwater, and all other pertinent conditions of this part are met. A permit issued under  
this rule may include a limit on total inorganic nitrogen in order to reflect improvement in  
existing groundwater quality.  
(e) A standard that has a limit that is higher than the limit set in subrules (2) and (4) to (7)  
of this rule may be established by the department in an individual case if the department  
determines that the standard set in subrules (2) and (4) to (7) of this rule is not economically  
or technically feasible, that a prudent alternative does not exist, and that establishing a  
higher limit is consistent with the promotion of the public health, safety, and welfare in  
light of the state's paramount concern for the protection of its natural resources. In  
approving a permit with a limit established under this subdivision, the department may  
Page 34  
prescribe criteria, limitations, or conditions as the department deems necessary to ensure  
that the conditions of R 323.2204 are met.  
(f) A standard that is more stringent than the standards described in this rule may be  
established in an individual case if the department determines that readily available and  
cost-effective treatment technology allows a more stringent standard to be met.  
(g) A standard that is more stringent than the standards described in this rule may be  
established for the protection of other environmental media, where applicable, if consistent  
with the requirements of all of the following:

microorganisms, or plants.  
(d) The discharger has not previously met the standard for the same discharge at a closer  
point of compliance.  
(e) The discharger demonstrates all of the following:  
(i) Meeting the standard at a closer point of compliance is economically burdensome or  
technically impractical.  
(ii) The concentration of the substance in the groundwater between the point of  
compliance that would be determined under subrule 1 of this rule and the point of  
compliance determined under this subrule shall not exceed that which would require  
remedial action pursuant to part 201 for the land use classification of the property on which  
the discharge is located.  
(iii) The discharger demonstrates that the adoption of an alternative or alternatives  
described in R 323.2219(1) to (3) is not prudent given the state's paramount concern for  
the protection of its natural resources or public trust in the resources from pollution,  
Page 37  
impairment, or destruction. In determining whether the discharger has successfully  
demonstrated that the adoption of an alternative or alternatives is not prudent, the  
department shall specifically solicit and consider public comment on the issue and make  
the determination in writing.  
(f) The discharger has in place and implements all of the following:

300 feet laterally from adjacent property that has a land use classification of residential,  
and not less than 800 feet laterally from adjacent property that has a land use classification  
of commercial or industrial. The department may authorize a lesser distance if, based upon  
hydrogeologic information contained in the report required under R 323.2221, there is no  
potential for impact to a wellhead protection zone or the use of ground- water on affected  
property.  
(i) A discharger may not use groundwater for human consumption if the groundwater  
does not meet state or federal standards for use as a potable water supply. A discharger  
shall record a restrictive covenant or other similar legal instrument describing this  
restriction against using groundwater for human consumption. Upon approval of the  
department, a discharger or subsequent owner of the property may modify the restrictive

Rule 2233. (1) For the purposes of this rule, the land treatment of wastewater shall be  
categorized into 1 of 3 of the following general processes:  
(a) Slow rate.  
(b) Overland flow.  
(c) Rapid infiltration.  
(2) If land application is considered part of the overall treatment to meet the standards of  
R 323.2222, then a discharger shall incorporate the use of slow rate or overland flow  
processes in the design.  
(3) A land treatment system shall comply with the general requirements for land treatment  
systems as described in subrule (4) of this rule as well as the specific requirements  
applicable to the type of land treatment system provided in R 323.2234 to R 323.2236. If  
a land treatment system includes a combination of 1 or more of the processes, then the  
overall system shall comply with the general requirements in subrule (4) of this rule and  
its individual component processes shall comply with the applicable requirements provided  
in R 323.2234 to R 323.2236. A discharger shall provide detailed design data, as described  
in this rule, to the department upon request.  
(4) A land treatment system shall meet all of the following requirements:  
(a) The system shall be designed, constructed, and operated as follows:  
(i) The system shall be designed and constructed to prevent surface runoff from either  
entering or exiting the system.  
(ii) The system shall be designed and constructed to provide even distribution of  
wastewater during application. A header ditch, where used, shall be designed and  
Page 46  
constructed to allow for complete drainage after each wastewater loading or shall be lined  
to prevent seepage.  
(iii) If vegetative cover is utilized and is considered part of the overall treatment system,  
then the design and construction of the system shall allow for the mechanical harvesting of  
vegetative cover.  
(iv) The system shall be designed, constructed, and operated to allow an appropriate

following:  
(A) Soil organisms to biologically decompose organic constituents in the wastewater.  
(B) Organic solids on the soil surface to decompose.  
(C) The soil to become aerated.  
(D) Vegetative cover to utilize available nutrients provided through the application of the  
wastewater.  
(E) Soil conditions to become unsaturated and aerobic.  
(F) Harvesting operations to occur at appropriate times.  
(v) The design hydraulic loading or application rate, whether daily, monthly, or annual,  
shall not be more than 7% of the permeability of the most restrictive soil layer within the  
solum over the area of the discharge as determined by the saturated hydraulic conductivity  
method or 12% of the permeability as determined by the basin infiltration method. The  
design annual hydraulic loading rate shall not be more than 3% of the permeability of the  
solum when determined by either the cylinder infiltration method or air entry permeameter  
test method. The methods referenced in this paragraph for determining soil permeability  
are adopted by reference in these rules and are contained in the publication entitled  
"Methods of Soil Analysis, Part 1, Physical and Mineralogical Properties," Second Edition,

or the Michigan Department of Environmental Quality, Waste Management Division, P.O.  
Box 30241, Lansing, Michigan 48909, at a cost at the time of adoption of these rules of  
$65.00, plus shipping and handling. A discharger, if utilizing published information, shall  
determine the methodology used to measure the reported hydraulic conductivity. If  
published information is utilized and if it is given as a range of expected values, then a  
discharger shall use the minimum value given the most restrictive soil layer within the  
solum when calculating the hydraulic loading or application rate.  
(vi) The system shall be designed, constructed, and operated so as to prevent the  
development of sodic conditions within the solum of the discharge area. Sodic conditions  
are considered to exist in the solum when the exchangeable sodium percentage, which is  
the percentage of the cation exchange capacity of a soil occupied by sodium, is more than  
15%. The exchangeable sodium percentage shall be calculated by dividing the quantity of  
exchangeable sodium in the solum, in milliequivalents per 100 grams of soil, by the cation  
exchange capacity, also in milliequivalents per 100 grams of soil, multiplied by 100.  
(b) If phosphorus adsorption within the solum or unsaturated soil column is part of the  
overall treatment process, then the system shall be designed as follows:  
(i) The available phosphorus adsorptive capacity of the solum or unsaturated soil column  
from within the discharge area shall be sufficient to provide the necessary treatment to  
ensure that the applicable limit established in the permit is not exceeded for the duration of  
the permit.  
Page 47  
(ii) The loading cycle shall be designed so as to provide the necessary contact time within  
the solum or unsaturated soil column required for phosphorus to be removed from the  
applied wastewater through adsorption processes.  
(iii) The available phosphorus adsorptive capacity of the discharge area shall be  
determined through either of the following methods:  
(A) By subtracting phosphorus levels of the unsaturated soil column, determined through  
on-site Bray-P1 analysis, from published phosphorus adsorption capacity data for the  
solum found within the discharge area. The method and procedure for the Bray-P1 analysis  
referenced in this subparagraph are contained in the publication entitled "Methods of Soil  
Analysis, Part 3 - Chemical Methods," American Society of Agronomy, 1996. The  
publication is adopted by reference in these rules and may be purchased from the American

plus shipping and handling.  
(B) By subtracting phosphorus levels of the unsaturated soil column, as determined  
through on-site Bray-P1 analysis, from the phosphorus adsorption maximum as determined  
through Langmuir isotherm analysis of on site soils, after adjustments for the concentration  
of phosphorus in the effluent and fraction of utilization within the solum are made. The  
method and procedure for determining phosphorus adsorption maximum through  
Langmuir isotherm analysis referenced in this subparagraph are contained in the  
publication entitled "Phosphate Sorption Isotherms for Evaluating Phosphorus  
Requirements of Soils," Soil Science Society of America Journal, Volume 34, American  
Society of Agronomy, 1970. The publication is adopted by reference in these rules and

R 323.2234 Slow rate land treatment.  
Rule 2234. (1) Slow rate land treatment is the application of wastewater to a vegetated  
land surface with the applied wastewater being treated as it flows through the plant and soil  
matrix. A portion of the flow is expected to percolate to the groundwater while the  
remainder is utilized by plants or lost through evaporation. A facility utilizing a slow rate  
system for the land treatment of wastewater shall design and construct the system under  
this rule.  
(2) The wastewater loading volume shall be designed so that the wastewater will be  
absorbed and held within the effective rooting zone of the vegetative cover established on  
the site receiving the wastewater.  
(3) The daily application rate, in inches per day of the wastewater, shall not exceed the  
permeability as determined by R 323.2233(2)(a)(v) multiplied by 24.  
(4) The header ditch drainage and the grading of the furrows, where utilized, shall be  
tested for equal liquid distribution before seeding.  
(5) The system shall be seeded with a mixture of perennial vegetative cover, which are  
grasses such as reed canary grass, tall fescue, and orchard grass, alone or in combination  
with legumes, such as clover, alfalfa, and birdsfoot trefoil, suited to the climate and the soil  
moisture conditions created as a result of the application of wastewater in accordance with  
the designed loading cycle. The department may approve alternative vegetative cover on a  
case-by- case basis, but may impose restrictions based upon the characteristics of the  
proposed alternative.  
(6) All furrow side slopes, where present, shall be designed and constructed to allow for  
periodic maintenance and or mechanical harvesting of vegetative cover.  
(7) The depth of the furrows of a ridge and furrow system, when utilized, shall be adequate  
to contain the highest proposed furrow stream. The furrow stream is the volume, in gallons  
per unit time, usually per minute, of wastewater discharged into the furrow.

R 323.2235 Overland flow treatment.  
Rule 2235. (1) Overland flow treatment of wastewater is the application of wastewater to  
the upper reaches of grass-covered slopes with excess wastewater collected at the end of  
Page 49  
the slopes for reapplication. A facility utilizing an overland flow system for the land  
treatment of wastewater shall design and construct the system under this rule.  
(2) A system may be constructed on a site that has slowly permeable soil, which is soil  
that has 50% or more of the soil particles pass through a no. 200 sieve, except that more  
permeable or coarser textured soil may be approved on a case-by-case basis depending on  
system design and wastewater strength. Suitable soil shall extend not less than 3 feet below  
the soil surface.  
(3) The system shall consist of an adequate number of cells that can be alternately loaded  
and rested, unless there is adequate storage or pretreatment, to allow loading and resting of  
a single cell.  
(4) The shape of each cell within the system shall be designed to minimize soil disturbance  
when constructing the system.  
(5) For a system utilizing more than 1 cell, the wastewater distribution system shall be  
designed and constructed so that individual cells within the system can be taken out of  
service for resting or other purposes without disruption to the remaining cells.  
(6) The header ditch drainage and the grading of the furrows, where utilized, shall be  
tested for equal liquid distribution before seeding.  
(7) All embankments and dikes shall be properly seeded in order to establish appropriate  
vegetative cover for the purpose of erosion prevention.  
(8) All furrow side slopes, where present, shall be designed and constructed to allow for  
the periodic maintenance and mechanical harvesting of vegetative cover.  
(9) The depth of the furrows of a ridge and furrow system, when utilized, shall be adequate  
to contain the highest proposed furrow stream. The furrow stream is the volume, in gallons  
per unit time, usually per minute, of wastewater discharged into the furrow.  
(10) The system shall be seeded with perennial grass, or other vegetation approved by the  
department as capable of high nutrient uptake, and be suited to the climate and soil moisture  
conditions created by the operation of the system. Vegetative cover, not less than 2 inches  
in length and capable of preventing significant erosion to furrows or embankments, shall  
be established before the system is used for wastewater treatment.

R 323.2236 Rapid infiltration.  
Rule 2236 .(1) Rapid infiltration is the application of wastewater to areas of moderately  
to highly permeable soil. The majority of applied wastewater percolates through the soil,  
and the treated effluent drains naturally to groundwater. The effluent is minimally treated  
as it travels through the soil matrix. Vegetation is not typically a part of the overall  
treatment process. The utilization of vegetation or its presence within a discharge area  
typically does not interfere with system performance. A facility utilizing rapid infiltration  
systems for the land treatment of wastewater shall design and construct the system under  
this rule.  
(2) The system shall consist of 2 or more cells or absorption areas that can be alternately  
loaded and rested or consist of 1 cell or absorption area preceded by an effluent storage or  
stabilization pond system. If only 1 cell or absorption area is provided, then the storage or  
stabilization pond shall be operated on a fill and draw basis and have sufficient capacity to  
allow intermittent loading of the cell or absorption area.  
Page 50  
(3) For a system that has more than 1 cell or absorption area, an individual cell or  
absorption area of the system shall be capable of being taken out of service without  
disrupting application to other cells or absorption areas of the system.  
(4) An appropriate hydraulic loading cycle shall be developed and implemented to  
maximize long-term infiltration rates and allow for periodic maintenance.
