ST. PAUL, Minn. (AP) — The Minnesota Pollution Control Agency has fined a Pipestone County dairy $10,000 for a 252,000-gallon manure spill that caused a fish kill and the temporary closing of a swimming beach.

The spill at Pater Dairy, which is seven miles south of Pipestone in southwestern Minnesota, happened on May 5, but wasn't reported to the state until May 13.

The MPCA says a pipe between two manure storage basins became plugged and caused the manure-contaminated water to overflow. After the spill was reported, the dairy owner used pumps, earthen berms and pumps to contain and recover some of the manure.

The Minnesota Department of Natural Resources closed the nearby Split Rock Creek State Park swimming beach after samples showed high levels of fecal coliform bacteria in the water.
