Premium Standard Farms (PSF), based in Princeton, MO, will invest millions of dollars to curtail hog odors and pollution from its Missouri operations, including the eventual elimination of lagoons.

PSF, the second-largest pork producer in the U.S., has already expended $12 million based on a 1999 Consent Decree with the state of Missouri that called for the development of “Next Generation” waste treatment technology.

PSF says this latest Consent Decree with Missouri officials acknowledges that it will take longer and cost more to complete the process of implementing environmental systems on selected farms. PSF will spend $9.5 million to convert hog manure into a high-value commercial fertilizer and eliminate the use of lagoons for manure treatment and storage. The new Consent Decree extends the deadline for implementation to July 2010.
