NR 151.055(2)
(2) There may be no significant discharge of process wastewater to waters of the state.
NR 151.055(3)
(3) The department shall consider all of the following factors when determining whether a discharge of process wastewater is a significant discharge to waters of the state:
NR 151.055(3)(c)
(c) Means of process wastewater conveyance to waters of the state.
NR 151.055(3)(d)
(d) Slope, vegetation, rainfall, and other factors affecting the likelihood or frequency of process wastewater discharge to waters of the state.
NR 151.055(3)(e)
(e) Available evidence of discharge to a surface water of the state or to a direct conduit to groundwater as defined under s.
NR 151.002 (11m).
NR 151.055(3)(f)
(f) Whether the process wastewater discharge is to a site that is defined as a site susceptible to groundwater contamination under s.
NR 151.015 (18).
NR 151.055(3)(g)
(g) Other factors relevant to the impact of the discharge on water quality standards of the receiving water or to groundwater standards.
NR 151.055 Note
Note: Existing technical standards contained in the U.S. department of agriculture natural resources conservation service field office technical guide may be used for managing process wastewater. When such standards are not applicable, the landowner or operator is expected to take reasonable steps to reduce the significance of the discharge in accordance with the agricultural performance standard and prohibition compliance requirements of this chapter. The Wisconsin department of agriculture, trade and consumer protection is responsible under s.
281.16 (3) (c), Stats., for developing additional management practices if needed.

Register December 2010 No. 660, eff. 1-1-11.
NR 151.06
NR 151.06 Clean water diversion performance standard. NR 151.06(1)(1)
All livestock producers within a water quality management area shall comply with this section.
NR 151.06(2)
(2) Runoff shall be diverted away from contacting feedlot, manure storage areas and barnyard areas within water quality management areas except that a diversion to protect a private well under s.
NR 151.015 (18) (a) is required only when the feedlot, manure storage area or barnyard area is located upslope from the private well.
NR 151.07(1)(1)
All crop producers and livestock producers that apply manure or other nutrients directly or through contract to agricultural fields shall comply with this section.
NR 151.07 Note
Note: Manure management requirements for concentrated animal feeding operations covered under a WPDES permit are contained in ch.
NR 243.
NR 151.07(2)
(2) This performance standard does not apply to the application of industrial waste and byproducts regulated under ch.
NR 214, municipal sludge regulated under ch.
NR 204, and septage regulated under ch.
NR 113, provided the material is not commingled with manure prior to application.
NR 151.07 Note
Note: In accordance with ss.
ATCP 50.04,
50.48 and
50.50, nutrient management planners, Wisconsin certified soil testing laboratories and dealers of commercial fertilizer are advised to make nutrient management recommendations based on the performance standard for nutrient management, s.
NR 151.07, to ensure that their customers comply with this performance standard.
NR 151.07 Note
Note: If an application of material to cropland is regulated under ch.
NR 113,
204, or
214, the management practices, loading limitations, and other restrictions specified in the applicable regulation apply to that application. However, nutrient management plans developed in accordance with this performance standard must account for all nutrient sources, including industrial waste and byproducts, municipal sludge, and septage. This means that the future application of manure and commercial fertilizer may be restricted by this performance standard due to other applications of industrial waste and byproducts, municipal sludge, and septage. In addition, it means that if industrial waste and byproducts, municipal sludge, or septage are placed in a manure storage structure and mixed with manure, the commingled material is also covered by this standard and must be accounted for by the producer when preparing and implementing a nutrient management plan.
NR 151.07(3)
(3) Manure, commercial fertilizer and other nutrients shall be applied in conformance with a nutrient management plan.
NR 151.07(3)(a)
(a) The nutrient management plan shall be designed to limit or reduce
the discharge of nutrients to waters of the state for the purpose of complying with state water quality standards and groundwater standards.
NR 151.07(3)(b)
(b) Nutrient management plans for croplands in watersheds that contain impaired surface waters or in watersheds that contain outstanding or exceptional resource waters shall meet the following criteria:
NR 151.07(3)(b)1.
1. Unless otherwise provided in this paragraph, the plan shall be designed to manage soil nutrient concentrations so as to maintain or reduce delivery of nutrients contributing to the impairment of impaired surface waters and to outstanding or exceptional resource waters.
NR 151.07(3)(b)2.
2. The plan may allow for an increase in soil nutrient concentrations at a site if necessary to meet crop demands.
NR 151.07(3)(b)3.
3. For lands in watersheds containing exceptional or outstanding resource waters, the plan may allow an increase in soil nutrient concentrations if the plan documents that any potential nutrient delivery to the exceptional or outstanding resource waters will not alter the background water quality of the exceptional or outstanding resource waters. For lands in watersheds containing impaired waters, the plan may allow an increase in soil nutrient concentrations if a low risk of delivery of nutrients from the land to the impaired water can be demonstrated.
NR 151.07(3)(c)
(c) In this standard, impaired surface waters are waters identified as impaired pursuant to
33 USC 1313 (d) (1) (A) and
40 CFR 130.7. Outstanding or exceptional resource waters are identified in ch.
NR 102.
NR 151.07(4)
(4) This section is in effect on January 1, 2005 for existing croplands under s.
NR 151.09 (4) that are located within any of the following:
NR 151.07(4)(a)
(a) Watersheds containing outstanding or exceptional resource waters.
NR 151.07 Note
Note: The purpose of the phased implementation of this standard is to allow the department sufficient time to work with the Department of Agriculture, Trade and Consumer Protection and local governmental units to develop and implement an information, education and training program on nutrient management for affected stakeholders.
