(July 25, 2005 - Raleigh, NC) Environmental Defense and the Southern Environmental Law Center (SELC) today called on state leaders to begin designing a multifaceted plan that will help the state's hog farmers convert polluting hog lagoons to waste management technologies that protect air and water quality and public health.  N.C. State University (NCSU) has announced that three more waste systems under review meet stringent environmental performance standards set forth in the so-called Smithfield Agreement, bringing to five the number of cleaner systems identified.  NCSU is releasing its findings in conjunction with today's five-year anniversary of the agreement, forged by the NC attorney general's office with Smithfield Foods.  Premium Standard Farms signed a similar agreement.  The agreements provided funding to NCSU to test cleaner technologies and obligated the companies to phase out lagoons on company-owned farms once technologies are identified that meet environmental and economic criteria.
