NR 528.07(4)(f)1.1. At a minimum, accumulated sediment shall be incorporated into the surface soil to a depth of at least 6 inches by disking or an equivalent process and may include other measures such as signage, restriction on site access or other appropriate measures.
NR 528.07(4)(f)2.2. The following waiting periods and access restrictions shall apply beginning on the date when the landspreading activity is completed:
NR 528.07(4)(f)2.a.a. When lands are used for the production of forage crops, landspreading shall occur only after harvest has occurred and before any new growth reaches 6 inches.
NR 528.07(4)(f)2.b.b. When lands are used for food crops intended for human consumption, a period of at least 14 months shall elapse prior to emergence of the food crop.
NR 528.07(4)(f)2.c.c. When lands are used for grazing, at least 30 days shall elapse prior to allowing access to non-dairy animals and at least 60 days shall elapse before allowing access to dairy animals.
NR 528.07(4)(f)2.d.d. When lands are subject to public access or used for the harvest of crops grown for fiber or any other forage or crop production, not covered in this subd. 2. a. to c., a period of at least 30 days shall elapse before the site may be accessed or used.
NR 528.07(5)(5)Dedicated sediment management site. The end use of landspreading or sediment treatment at a dedicated management site may be chosen if the sites are owned or leased by a municipality or other responsible unit of government. The sediment manager shall assume any additional site management, site monitoring and recordkeeping responsibilities that are necessary to minimize risk to public health, safety and the environment.
NR 528.07(5)(a)(a) When sediment is used at a dedicated site, the sediment manager shall ensure that the appropriate portions of the certification form provided by the department are completed. Based on the information obtained in accordance with s. NR 528.06, the sediment manager may choose to use the accumulated sediment for productive purposes including the growth of herbaceous or woody plants for harvest or for treatment to reduce contaminants in the accumulated sediment in accordance with this subsection.
NR 528.07(5)(b)(b) All of the following restrictions shall apply to dedicated sediment management sites:
NR 528.07(5)(b)1.1. The locational criteria in s. NR 528.04 (1) shall be met.
NR 528.07(5)(b)2.2. The sediment shall be applied to a depth of 18 inches or less below ground surface.
NR 528.07(5)(b)3.3. When the dedicated site is used for sediment treatment so as to attenuate or reduce contaminants in the accumulated sediment, only non-food chain crops or woody plants for harvest or phyto-remediation purposes may be grown.
NR 528.07(5)(b)4.4. In cases where the annual application rate or lifetime loading limit in sub. (4) (b) are not exceeded, the provisions of sub. (4) (b) 2. do not apply. In cases where the 5 dry tons per acre annual application rate limitation or the 15 dry tons per acre site life limit are exceeded, the sediment manager shall ensure that sub. (4) (b) 2. is followed as well as take any additional measures or practices that may be necessary to ensure safe long-term site use. These may include practices such as the collection and evaluation of contaminants in soils, plant tissue, other environmental receptors or monitoring devices. The sediment manager shall track the sediment application rates and cumulative site loading totals for contaminants in soil or other receptors as appropriate. The sediment manager shall ensure that any additional measures are implemented that may be necessary such as enhanced site management practices to control run-on and runoff and erosion control practices. At a minimum, the erosion control requirements of s. NR 528.04 (3) shall be met.
NR 528.07(5)(b)5.5. Accumulated sediment may be applied on frozen ground and on slopes greater than 6% or more provided the sediment management is performed in compliance with s. NR 528.04 (3) and adequate and permanent run-on and runoff controls are in place and maintained.
NR 528.07(5)(b)6.6. Sediment may not be applied when precipitation capable of producing runoff is forecast within 24 hours of the time of planned application, or during or immediately after a precipitation event.
NR 528.07(5)(b)7.7. In all cases where a pathogen risk exists due to the presence of pathogens, as indicated by evidence of the pathogen or indicator organism and level per s. NR 528.06 (3) (b) 4., then the waiting periods in sub. (4) (f) apply.
NR 528.07(5)(b)8.8. In all cases where a pathogen risk exists due to the presence of pathogens, no grazing is allowed and no human food chain crops may be grown where the sediment has been applied.
NR 528.07(5)(b)9.9. In all cases where a pathogen risk exists, permanent public access controls shall be put in place and access restricted during any year when the sediment application occurs.
NR 528.07(5)(c)(c) The sediment manager shall ensure that an affidavit is filed indicating that the site was used for a dedicated sediment management site in the registrar of deeds office in the county where the site is located.
NR 528.07(5)(d)(d) The sediment manager shall ensure that all appropriate completed certification forms, all sediment sampling results and all monitoring data and site use and sediment loading records are retained in accordance with s. NR 528.08.
NR 528.07(6)(6)Small quantity, coarse grained sediment management. The sediment manager may choose to manage certain kinds of coarse grained sediment as provided under this subsection.
