				POND SYSTEMS.
(a)
Design
				limitations.
Absorption pond systems shall conform to the design
				requirements in s.
				NR
				110.255(1).
(b)
Effluent limitations.
1. The discharge to an absorption pond system
				may not exceed a monthly average BOD5 concentration of 50 mg/l.
2. The maximum hydraulic application rate to
				an absorption pond system shall be determined on a case-by-case basis in
				accordance with s.
				NR
				110.255(1) (a) 2.
3. The discharge to an absorption pond system
				which is subject to the groundwater quality standards in ss.
				NR
				140.10 and shall comply 140.12 with the following
				limitations:
a. The monthly average total
				nitrogen concentration may not exceed 10 mg/l.
b. The total dissolved solids concentration
				may not exceed 500 mg/l.
c. The
				chloride concentration may not exceed 250 mg/l.
4. If an absorption pond system has been
				granted an exemption to groundwater quality standards under s.
				NR
				140.28, the discharge requirements for nitrogen, total
				dissolved solids and chloride will be determined by the department on a
				case-by-case basis. Information to be considered in approving alternate
				limitations shall include:
a. Alternate
				concentration limits under ch. NR 140;
b. Qualifications on the exemption, if any
				exist;
c. Level of treatment of the
				wastewater for the particular contaminant;
d. Removal capability prior to discharge to
				the treatment system;
e. Expected
				increase in the concentration of a pollutant in groundwater downgradient at the

				application rate, total dissolved solids and chlorides; and may require
				effluent limitations for additional substances on a case-by-case basis in order
				to protect and maintain groundwater quality as required in ch. NR 140.
Note: The effluent limitations in par. (b) 3. have been
				  established to provide compliance with the groundwater enforcement standards
				  for nitrate, total dissolved solids and chloride. The department has determined
				  that it is not technically and economically feasible for absorption pond
				  systems to comply with the preventive action limits for these substances. These
				  effluent limitations, in combination with groundwater monitoring requirements,
				  will assist the department in minimizing the levels of nitrate, total dissolved
				  solids and chloride in the groundwater, to the extent technically and
				  economically feasible. Groundwater enforcement standards and preventive action
				  limits are specified in ss.
				  NR
				  140.10 and

Current through June 24, 2024
(1) PROHIBITED
				  OVERFLOWS. Sanitary sewer overflows and sewage treatment facility overflows are
				  prohibited and may not be approved by the department nor authorized in a permit
				  issued by the department. If applicable to an overflow event, permittees shall
				  provide information that will enable the department to determine whether any of
				  the following conditions exist:
Note: When used without qualification in this chapter, the
					 word "overflow" includes both sanitary sewer overflow and sewage treatment
					 facility overflow.
(a) The sanitary
				  sewer overflow or sewage treatment facility overflow was unavoidable to prevent
				  loss of life, personal injury, or severe property damage.
(b) There were no feasible alternatives to
				  the sanitary sewer overflow or sewage treatment facility overflow such as the
				  use of auxiliary treatment facilities or adequate back-up equipment, retention
				  of untreated wastes, reduction of inflow and infiltration, or preventative
				  maintenance activities.
Note: When evaluating feasibility of alternatives, the
					 department may consider factors such as technical achievability, the
					 relationship between the control of storm water and the control of infiltration
					 and inflow into the sewage collection system, costs and affordability of
					 implementation and risks to public health, the environment, and welfare of the
					 community served by the sewage collection system.
(c) The sanitary sewer overflow or the sewage
				  treatment facility overflow was caused by unusual or severe weather related
				  conditions such as large or successive precipitation events, snowmelt,
				  saturated soil conditions, or severe weather occurring in the area served by
				  the sewage collection system or sewage treatment facility.
(d) The sanitary sewer overflow or the sewage
				  treatment facility overflow was unintentional, temporary, and caused by an
				  accident or other factors beyond the reasonable control of the
				  permittee.
