(1) Streams, wetlands, and drainage ditches.

If applying manure, or process wastewater, within 300 feet of the ordinary high water of a protected stream, wetland, or drainage ditch, a 25-foot vegetated buffer shall be maintained along the stream, wetland, or drainage ditch, and manure must be injected or incorporated within 24 hours.
(b) Unprotected. If applying manure, or process wastewater, within 50 feet of the ordinary high water of an unprotected stream, wetland, or drainage ditch, one rod (16.5 feet) of vegetated buffer shall be maintained along the stream, wetland, or drainage ditch.
(2) Lakes. If applying manure, or process wastewater, within 300 feet of the ordinary high water of any lake, a 25-foot vegetated buffer shall be maintained along the lake, and manure must be injected or incorporated within 24 hours.
(D) Right-of-Way. Manure shall not be applied to the right-of-way of public roads.

(2) If no pollution hazard exists, a minimum distance of 300 feet shall be maintained between manure, or process wastewater, and any public water supply well.
(F) Residences. Animal manure, and process wastewater, shall not be applied within 100 feet of a residence unless it is injected or immediately incorporated into the soil. However, permission by the resident may be granted to spread closer. When determining the distance between a residence and manure application, the distance shall be measured from the residence, not property lines, to manure application.
