If the department finds, after review of this material, that the proposal would not provide the information necessary to make a determination, a response will be issued which contains recommendations on how the study should be amended. All reports and research publications pertaining to the facility shall be provided to the department. The final report shall, at a minimum, summarize the project performance, any limitations and areas of further study.
NR 518.04(3)(3)Lime sludge. Facilities used for the landspreading of lime sludges from papermills or water supply treatment facilities are exempt from the requirements of this chapter provided that the proposal is reviewed and approved by the department and the material meets the following requirements. This subsection does not apply to lime sludges from papermills which were being landspread prior to July 1, 1996.
NR 518.04(3)(a)(a) Analyzed in accordance with s. NR 518.06 (1),
NR 518.04(3)(b)(b) Determined by the department to have value as a soil conditioner or fertilizer, and
NR 518.04(3)(c)(c) Applied in accordance with accepted agricultural practices and any department issued approval.
NR 518.04 NoteNote: Lime sludges from papermills which were being landspread prior to July 1, 1996, are exempt under sub. (1) (j).
NR 518.04(4)(4)Industrial sludges. Facilities used exclusively for the landspreading of nonhazardous industrial sludges are exempt from the requirements of this chapter provided that the material is:
NR 518.04(4)(a)(a) Analyzed in accordance with s. NR 518.06 (1),
NR 518.04(4)(b)(b) Determined by the department to have value as a soil conditioner or fertilizer. The department may on a case-by-case basis require greenhouse or experimental field studies and may consider federal regulations, technical guidelines and other related research in determining whether a sludge has value as a soil conditioner or fertilizer,
NR 518.04(4)(c)(c) Generated at an industrial wastewater treatment facility and the landspreading facility has been approved or permitted under ch. NR 214, and
NR 518.04(4)(d)(d) Not repeatedly applied such that excessive accumulation of hazardous substances occur in soil or vegetation, or cause a detrimental effect on surface water quality or cause a detrimental effect on groundwater quality or cause or exacerbate an attainment or exceedance of any preventive action limit or enforcement standard at a point of standards application as defined in ch. NR 140.
NR 518.04(5)(5)Coal ash. Facilities used for the landspreading of coal ash or ash produced by burning coal with other fuels are exempt from the requirements of this chapter provided that the proposal is reviewed and approved by the department and the material is:
NR 518.04(5)(a)(a) Analyzed in accordance with s. NR 518.06 (1),
NR 518.04(5)(b)(b) Determined by the department to have value as a soil conditioner or fertilizer,
NR 518.04(5)(c)(c) Applied in accordance with accepted agricultural practices and any department issued approval. As part of this approval, the department may require additional testing, monitoring, reporting or other information as appropriate, and
NR 518.04(5)(d)(d) Not repeatedly applied such that excessive accumulation of hazardous substances occur in soil or vegetation, or cause a detrimental effect on surface water quality or cause a detrimental effect on groundwater quality or cause or exacerbate an attainment or exceedance of any preventive action limit or enforcement standard at a point of standards application as defined in ch. NR 140.
NR 518.04(6)(6)Wood ash.
NR 518.04(6)(a)(a) Facilities used for the landspreading of wood ash from the combustion of untreated wood with no additives, preservatives or other alterations other than kiln drying are exempt from the requirements of this chapter provided that storage, handling, transportation and landspreading follow best management practices to minimize uncontrolled dispersion by wind and water and provided that the following requirements are met by those responsible for landspreading activities or the wood ash operator:
NR 518.04 NoteNote: The term “facilities” used in this subsection means the land upon which wood ash is applied. Section NR 500.08 (5) (b) 1. exempts wood ash storage, handling, transportation and landspreading activities for small quantity wood ash generators. Section NR 500.08 (5) (b) 2. exempts wood ash storage, handling and transportation activities when wood ash is managed in accordance with this subsection.
NR 518.04(6)(a)1.1. An initial bulk chemical analysis shall be performed on a representative sample of wood ash to determine the composition and neutralizing index. Testing shall be performed by the generator or generator’s designee in accordance with a department approved testing procedure. The department may limit landspreading based on the level of contaminants found in this testing procedure.
NR 518.04(6)(a)2.2. Landspreading shall be for the purpose of beneficially using the wood ash for soil pH adjustment or nutrient addition using accepted agricultural practices.
NR 518.04(6)(a)3.3. Maximum one time application rates shall be limited to 15 dry tons per acre and a total cumulative application limited to 50 dry tons per acre.
NR 518.04 NoteNote: The department recommends the wood ash application rate be adjusted to target soil pH to promote crop yields.
NR 518.04(6)(a)4.4. Wood ash which is top dressed may not be landspread in the following areas:
NR 518.04(6)(a)4.a.a. Within 100 feet of navigable bodies of water, such as streams or ponds, a wetland or a floodplain.
NR 518.04(6)(a)4.b.b. Within 1,000 feet of public water supply wells or 200 feet of private water supply wells.
