(b) No mechanical application of liquid manure unless:
1. Pre-tillage is completed unless exempt under sub. (c); and
2. Liquid manure is injected or incorporated within 24 hours to no more than 6 inches below ground; and
3. At least one of the following is implemented:
a. Total liquid manure application is limited to sub. (10)(b)3. Table 1 rates or to the UW A2809 annual application rate, whichever is less, to prevent hydraulic overloading of the soil.
b. Liquid manure is applied within 10 days of the planting date or applied on perennial or other established crop.
c. Liquid manure is treated to substantially reduce pathogen levels via practices to a fecal coliform bacteria density of less than 500,000 most probable number or colony-forming units per 100 milliliter sample.
(c) Pre-tillage or incorporation is not required if cropland or pastures meet long term no till or has perennial or established crops.
(12) For soils with 5 to 20 feet to Silurian bedrock, the following shall apply:
(a) No mechanical application of liquid manure unless:
1. Pre-tillage is completed unless exempt under sub. (b); and
2. Liquid manure is injected or incorporated within 24 hours to no more than 8 inches below ground; and
3. At least one of the following is implemented:
a. Total weekly liquid manure application is limited to sub. (10)(b)3. Table 1 rates, or to the UW A2809 annual application rate, whichever is less, to prevent hydraulic overloading of the soil.
b. Liquid manure is applied within 10 days of the planting date or applied on perennial or other established crop.
c. Liquid manure is treated to substantially reduce pathogen levels via practices to a fecal coliform bacteria density of less than 500,000 most probable number or colony-forming units per 100 milliliter sample.
(b) Pre-tillage or incorporation is not required if cropland or pastures meet long term no till, or has perennial or established crops.
(13) Mechanical manure applications are prohibited within:
(a) 1000 feet of a community water system as defined in s. NR 811.02. (b) 250 feet of a private water system and non-community water system as defined in s. NR 812.07. (c) An area within 300 feet upslope or 100 feet downslope of a direct conduit to groundwater.
(d) 100 feet of defined channels that lead to sub. (a), (b), or (c).
(14) Mechanical manure applications are prohibited within 100 feet of an area in a closed depression unless the manure is injected or incorporated within 24 hours or prior to a rain event, whichever comes first. This does not apply to areas following long term no till practices or with perennial or established crops.
(15) No surface application of manure on slopes of 6 percent or greater in cropland and pasture areas that have defined channels that drain to a closed depression, unless the material is incorporated within 24 hours. This does not apply to areas following long term no till practices or with perennial or established crops.
(16) Practices shall retain land applied manure on the soil where they are applied with minimal movement to maintain setback distances specified in subs. (13) and (14).
Section 14. NR 243.143 is created to read:
NR 243.143. Silurian bedrock performance standards. Owners or operators that mechanically apply manure directly or through contract or other agreement to cropland or pasture areas that meet the definition of Silurian bedrock under s. NR 151.015(17) shall comply with s. NR 151.075. Section 15. Effective Date. This rule takes effect on the first day of the month following publication in the Wisconsin Administrative Register as provided in s. 227.22 (2) (intro.), Stats. Section 16. Board adoption. This rule was approved and adopted by the State of Wisconsin Natural Resources Board on [DATE].
