The maximum daily volume of liquid waste applied shall be limited to 13,500 gallons per acre per day (1/2 inch) except that when the ground is frozen or snow covered it shall be limited to 6,800 gallons per acre per day (1/4 inch). NR 214.17(4)(d)6.6. The maximum weekly volume of liquid waste applied shall be limited according to Table 3. NR 214.17(4)(d)7.7. The total pounds of chloride applied shall be limited to 170 pounds per acre per year or 340 pounds per acre per 2 year period. NR 214.17(4)(d)8.8. The total pounds of sodium applied may be limited to prevent alteration of soil properties or groundwater contamination. NR 214.17(4)(d)9.9. The total pounds of nitrogen applied per acre per year shall be limited to the nitrogen needs of the cover crop minus any other nitrogen, including fertilizer or manure, added to the landspreading site. Nitrogen applied can be calculated on the basis of plant available nitrogen, as long as the release of nitrogen from the organic material is credited to future years. NR 214.17(4)(d)10.10. For whey, not including whey by-products, where the nitrogen content has not been determined through sampling and analysis, the nitrogen application rate shall be limited by limiting the yearly hydraulic application rate for a site to 27,150 gallons per acre (1 inch) the first year, 20,360 gallons per acre (3/4 inch) the second year, and 13,600 gallons per acre (1/2inch) the third and succeeding years. NR 214.17(4)(e)1.1. The volume of by-product solids landspread may not alter the characteristics or structure of the soil such that the crop is adversely affected or erosion or permeability problems occur. NR 214.17(4)(e)2.2. The total quantity of by-product solids applied to the soil shall be within acceptable agricultural practices taking into account the carbon to nitrogen ratio, total nitrogen and the moisture content of the by-product solid. NR 214.17(4)(e)3.3. The volume of by-product solids landspread shall be limited to prevent surface runoff of solids or leachate, leaching of contaminants to groundwater and objectionable odors. NR 214.17(4)(e)4.4. The total pounds of chloride applied shall be limited to 170 pounds per acre per year or to 340 pounds per acre per 2 year period. NR 214.17(4)(e)5.5. The total pounds of sodium applied may be limited to prevent alteration of soil properties or groundwater contamination. NR 214.17(4)(e)6.6. The total pounds of nitrogen applied per acre per year shall be limited to the nitrogen needs of the cover crop minus any other nitrogen, including fertilizer or manure, added to the landspreading site. Nitrogen applied can be calculated on the basis of plant available nitrogen, as long as the release of nitrogen from the organic material is credited to future years. NR 214.17(4)(e)7.7. The by-product solids shall be plowed, disced, injected or otherwise incorporated into the surface soil layer as specified in the WPDES permit or approved management plan. NR 214.17(4)(e)8.8. If it is necessary to stockpile solids in the field, the piles shall be spread within 72 hours or less as specified in the WPDES permit or management plan. NR 214.17(5)(a)(a) The discharge to landspreading systems shall be monitored for total daily discharge volume. NR 214.17(5)(b)(b) The department may require in a WPDES permit that the discharge to the system be monitored for BOD5, total suspended solids, forms of nitrogen, chloride, metals or any other pollutant that may be present. The department shall select the pollutants to be monitored and the required frequency of monitoring on a case-by-case basis by considering the potential public health impacts, probable environmental impact, soil and geologic conditions, past operating performance, concentrations and characteristics of pollutants in the discharge and other relevant information. NR 214.17(5)(c)(c) The department may require electronic or paper submittal of discharge monitoring reports and land application forms. NR 214.17(6)(a)(a) Vehicles used for transporting or landspreading the waste shall be maintained to prevent spillage or leakage. NR 214.17(6)(b)(b) The landspreading vehicle shall be moving forward at all times of application unless it is equipped with a high pressure spray nozzle which evenly distributes the waste over the land. NR 214.17(6)(c)(c) Management plan. The department shall require each landspreading system owner or operator to submit a management plan for optimizing system performance and demonstrating compliance with the requirements of this chapter. Following approval by the department, the treatment system shall be operated in conformance with the management plan. If the facility wishes to operate differently than specified in the approved plan, a written request shall be submitted to the department for approval to amend the management plan. The plan shall specify information on pretreatment processes, site identification on plat and soil maps, aerial photographs, if available, description of all site limitations, vegetative cover management and removal, availability of storage, type of transporting and spreading vehicle, load and rest schedules, monitoring procedures, contingency plans for periods of adverse weather or odor or nuisance abatement and any other pertinent information. NR 214.17(7)(7) Soils investigation and groundwater monitoring requirements. Soil investigation and groundwater monitoring requirements are specified in ss. NR 214.20 and 214.21. NR 214.17 HistoryHistory: Cr. Register, June, 1990, No. 414, eff. 7-1-90; CR 09-123: cr. (5) (c) Register July 2010 No. 655, eff. 8-1-10. NR 214.18(1)(1) Applicability. Only sludges which have been exempted from regulation under ch. NR 518 and have been shown to have beneficial properties as a soil conditioner or fertilizer and not have detrimental effects on the soil, crops or groundwater may be spread on the land. A WPDES permit is required for the spreading of sludge on land.
