NR 113.07(3)(b)11.b.b. The nitrogen recommendations shall be in accordance with the University of Wisconsin - Extension bulletin A-2809 dated November 2012, which is incorporated by reference or other soil nutrient determination and soil sampling guidance approved by the department.
NR 113.07 NoteNote: Copies of Bulletin A-2809 dated November 2012 are available for inspection in the offices of the department of natural resources and the legislative reference bureau.
NR 113.07(3)(b)12.12. Any person who land applies septage shall comply with the minimum separation distances and maximum slope requirements in Table 3.
NR 113.07(3)(b)13.13. Septage may not be landspread where it is likely to adversely affect a threatened or endangered species or its designated critical habitat or a historical site.
NR 113.07(3)(c)(c)
NR 113.07(3)(c)1.1. Septage may be landspread seasonally on or into soils with a seasonal high groundwater level at a depth greater than one foot but less than 3 feet from the surface if the landspreading is limited to times when the soil is not saturated within 3 feet of the surface.
NR 113.07(3)(c)2.2. Septage may be surface applied to hay fields after the hay has been harvested but not after the new growth of hay has reached a height of 6 inches above cut height.
NR 113.07(3)(c)3.3.
NR 113.07(3)(c)3.a.a. A site shall be approved by the department based on information available to the department at the time of the site request.
NR 113.07(3)(c)3.b.b. A site approval may be rescinded if information is provided or available to the department showing the information used by the department to approve a site is not consistent with the new information and the site is deemed by the department to be inadequate to protect public health and waters of the state.
NR 113.07(3)(c)3.c.c. The department may request a site approval to be re-reviewed when ownership issues are unclear, violations such as overapplication are identified, or other potential concerns are identified about a specific site.
NR 113.07(3)(c)3.d.d. A site that is approved by the department or by a county and meets all the separation requirements at the time of approval may not have the site approval rescinded for separation distance encroachment by residences, businesses, or recreational areas for a period of 5 years. This 5-year period shall run from the occupancy date of the encroachment.
NR 113.07(3)(c)4.4. Site management plans may not allow surface spreading of septage on disposal sites with a slope greater than 6 percent.
NR 113.07(3)(c)5.5. Surface application on snow covered fields requires plowed spreading lanes (snow removal) perpendicular to the slope when the snow depth is greater than 6 inches. Plowed lanes may not be wider than 20 feet and no closer than 40 feet.
NR 113.07(3)(d)(d)
NR 113.07(3)(d)1.1. Pathogens shall be reduced by one of the following methods:
NR 113.07(3)(d)1.a.a. The site restrictions under subd. 2. shall be met when septage is applied to agricultural land, forest, or a reclamation site.
NR 113.07(3)(d)1.b.b. The pH of septage applied to agricultural land, forest, or a reclamation site shall be raised to 12.0 or higher by alkali addition and, without the addition of more alkali, shall remain at 12.0 or higher for 30 minutes, and the site restrictions under subd. 2. a. to d. shall be met. When this option is utilized, each container of septage that is applied shall be monitored for compliance. For the purposes of measuring septage at a pH of 12.0 standard units, the pH shall be measured to 3 significant digits.
NR 113.07 NoteNote: To achieve accurate pH monitoring results use 3 lots of narrow range pH paper or strips with 3 distinct lot numbers, or calibrate pH meters frequently with appropriate buffer solutions.
NR 113.07(3)(d)2.2. Pathogen reduction is achieved by all of the following site restrictions:
NR 113.07(3)(d)2.a.a. Food crops with harvested parts that touch the septage/soil mixture and are totally above the land surface may not be harvested for 14 months after application of septage.
NR 113.07(3)(d)2.b.b. Food crops with harvested parts below the surface of the land may not be harvested for 20 months after application of septage when the septage remains on the land surface for 4 months or longer prior to incorporation into the soil.
NR 113.07(3)(d)2.c.c. Food crops with harvested parts below the surface of the land may not be harvested for 38 months after application of septage when the septage remains on the land surface for less than 4 months prior to incorporation into the soil.
NR 113.07(3)(d)2.d.d. Food crops, feed crops and fiber crops may not be harvested for 30 days after application of septage.
NR 113.07(3)(d)2.e.e. Animals may not be allowed to graze on the land for 30 days after application of septage.
