NR 214.18(5)(c)5.5. A description of any adverse environmental, health or social effects that occurred due to sludge application during the preceding reporting period.
NR 214.18(5)(c)6.6. A description of any violation of the sludge management plan.
NR 214.18(5)(d)(d) The department may require electronic or paper submittal of discharge monitoring reports and land application forms.
NR 214.18(6)(6)Operating requirements.
NR 214.18(6)(a)(a) Spillage or leakage from vehicles used for transporting or spreading sludge shall be prevented.
NR 214.18(6)(b)(b) The vehicle shall be moving forward at all times of application unless it is equipped with a high pressure spray nozzle which evenly distributes the sludge over the land.
NR 214.18(6)(c)(c) Management plan. The department shall require each sludge spreading 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 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: sludge volumes and characteristics, beneficial or nondetrimental fertilizer or soil conditioner properties, production and pretreatment processes, description of all site limitations, vegetative cover control and removal, availability of storage, type of transportation and spreading vehicle, sludge application rates, load and rest schedules, contingency plans for periods of adverse weather, odor and nuisance abatement or any other pertinent information.
NR 214.18(7)(7)Soil investigation and groundwater monitoring requirements. Soil investigation and groundwater monitoring requirements are specified in ss. NR 214.20 and 214.21.

subch. III of ch. NR 214Subchapter III — Site Investigation and Monitoring
NR 214.20NR 214.20Soil investigation requirements.
NR 214.20(1)(1)Applicability. This section is applicable to all new, expanded or modified land treatment systems receiving liquid wastes, by-product solids and sludges from industrial facilities for which a plan approval under s. 281.41, Stats., and ch. NR 108 or a WPDES discharge permit under ch. 283, Stats., is required. It is also applicable to those existing dischargers which need to demonstrate according to s. NR 214.06 (1) that their land treatment system complies with groundwater protection requirements although the system does not meet each specific design standard.
NR 214.20(2)(2)Professional qualifications. The department shall accept soil test pit evaluations, soil classifications and soil boring logs performed by a qualified soil scientist, engineer or other qualified individual. Qualifications shall include a degree from an accredited institution of higher education or field experience in soil investigation, interpretation and classification.
NR 214.20(3)(3)Technical procedures. All technical procedures used to investigate a wastewater disposal facility shall be the current standard procedures as specified by the American society for testing and materials, United States geologic survey, standard methods for the examination of water and wastewater, or other equivalent or appropriate methods approved by the department. Test procedures used shall be specified. Any deviation from a standard method shall be explained in detail with reasons provided.
NR 214.20(4)(4)Soil evaluations for landspreading and sludge spreading systems. The following soil related information shall be submitted for sludge spreading systems or landspreading systems for liquid waste or organic by-product solids:
NR 214.20(4)(a)(a) Individual treatment site locations identified on topographic maps, plat maps or aerial photographs,
NR 214.20(4)(b)(b) Relevant, existing soil survey information such as that assembled by the U.S. department of agriculture, soil conservation service including the soil names, percent slope, relative permeability, available water capacity, organic matter content and current land use,
NR 214.20(4)(c)(c) A detailed soils map displaying the location of the various soils on the site at a scale of not more than 2,000 feet to the inch,
NR 214.20(4)(d)(d) Laboratory determined or estimated soil cation exchange capacity,
NR 214.20(4)(e)(e) Agronomic soil nutrient testing results for making fertilizer and liming recommendations for cover crop growth using procedures such as those employed by the university of Wisconsin - cooperative extension program,
NR 214.20(4)(f)(f) Additional soil related information that may be required by the department on a case-by-case basis.
NR 214.20(5)(5)Treatment systems where groundwater monitoring wells are not required. For absorption pond, ridge and furrow, spray irrigation, overland flow and subsurface absorption systems where groundwater monitoring wells are not required, or for those sites which are being investigated for potential future use as such systems, the soils evaluation shall contain the following information and investigation, at a minimum:
NR 214.20(5)(a)(a) The location, soil survey, soil cation exchange capacity and soil nutrient content information as specified for landspreading systems in sub. (4).
NR 214.20(5)(b)(b) A sufficient number of soil test pits shall be excavated to adequately define the soil conditions found on the site.
