Section NR 206.07 - General conditions required for all land disposal systems(1) DESIGN LIMITATIONS. (a) A land disposal system shall be constructed in accordance with the design criteria in ch. NR 110, or the appropriate rules promulgated by the department of safety and professional services for large scale subsurface soil absorption systems.(b) Background groundwater monitoring data described in ss. NR 140.20(1) and 206.10(4) shall be collected prior to the design of a land disposal system, and submitted to the department as part of the facility plan required in s. NR 110.09.(c) Land disposal systems shall be designed and operated to maintain compliance with the groundwater quality standards contained in ch. NR 140, as required by s. NR 140.22(1).(2) OPERATIONAL REQUIREMENTS. (a) No discharge to a land disposal system may exceed the loadings specified in the WPDES permit for the system.(b) No discharge to the system may have physical or chemical characteristics which prevent the proper operation of the land disposal system.(c) The discharge of toxic or hazardous pollutants to land disposal systems is prohibited unless the applicant can demonstrate and the department determines that the discharge of such pollutants will be in such small quantities that no detrimental effect on groundwater or surface water will result. The criteria used shall include but not be limited to the toxicity of the pollutant, capacity of the soil to remove the pollutant, degradability, usual or potential presence of the pollutant in the existing environment, method of application and all other relevant factors.(d) The underground injection of municipal and domestic wastewaters through a well is prohibited.(e) All municipal and domestic wastewater land disposal systems shall be preceded by a biological, chemical or physical treatment or a combination of treatments approved by the department. Industrial waste discharges tributary to the municipal treatment works shall be in compliance with applicable pretreatment standards under s. NR 211.30.(f) For a land disposal system located on a site where soil, geologic or other conditions may result in an increased possibility of groundwater contamination, the department may require additional treatment prior to discharge to such land disposal systems.(g) Discharge to a land disposal system shall be limited so that the discharge and any precipitation which falls within the boundary of the disposal system during such discharge does not overflow the boundary of the system unless the WPDES permit authorizes collection and discharge of runoff to a surface water.(h)1. All land disposal facilities shall be operated in accordance with an approved management plan. The management plan shall conform to the requirements of s. NR 110.25(3m).2. For all land disposal facilities approved after December 1, 1990, an acceptable management plan shall be submitted with the construction plans and specifications.3. For land disposal facilities constructed prior to December 1, 1990, an acceptable management plan shall be submitted in accordance with a schedule established by the department.4. If operational changes are needed the management plan shall be revised.5. All management plans and revisions to management plans shall be submitted to the department for review to determine adequacy and compliance with code requirements.Wis. Admin.
