General Guidelines for Cattle/Dairies - August 9, 1996

1. All solids from paved areas must be collected in a waste storage facility. Surface runoff from paved areas must be minimized by the use of practices such as gutters, roofs, and diversion ditches.
   
   
2. All liquids from paved and milking areas must be collected in a waste storage facility or in some other way treated to insure only a de minimus discharge of pollutants in a storm event less severe than the 25 year, 24 hour storm event. For any facility wishing to install a system other than a waste storage facility, a request must be made for a site specific determination in accordance with the criteria established in 19.F. of the THIRD Guidance Memo dated August 9, 1996.
   
   
3. All dry stacks must include either a roof and be able to retain all liquids; or all liquids must be handled like those from paved and milking areas as described in item 2 above.
   
   
4. A 100 foot filter strip must be established between lounging areas that are typically void of vegetation during the winter months and any perennial streams, ponds, and drainage ways. The filter strip must be protected by a fence. Where a 100-foot filter strip cannot be installed, diversions, settling basins, or other conservation practices must be used.
   
   
5. A filter strip of at least 25 feet must be established between heavy traffic areas with sparse vegetation and drainage ways. The filter strip must be protected by a fence.
   
   
6. Perennial streams surrounded by a good stand of pasture must be protected by a fence when the streams are in pastures that are in close proximity to the dairy operations or when the livestock typically cross the stream from the pasture to get to the barn, Eroded or barren stream banks due to animal traffic are evidence that animal exclusion is needed.
   
   
7. Where stream buffers are intended for runoff pollutant filtering, measures to minimize channelization and promote sheet flow must be installed and maintained.
   
   
8. Stream crossings must be installed where needed.
   
   
9. Stock trails must be installed as needed.
   
   

10. A properly designed and implemented Waste Utilization Plan must be developed and implemented.
