The North Carolina Department of Environmental Quality Division of Water Resources (DWR) has approved permit modification requests to install anaerobic digesters at four animal feeding operations participating in a biogas processing project with Align RNG, LLC, and ABC member. After extensive review of the applications and consideration of community concerns, DWR added additional sampling conditions and site-specific changes to the best management practices. Four permitted swine operations, located in Duplin and Sampson counties, submitted applications to DWR to modify their existing permits. Three of these facilities requested to install new in-ground, synthetically-lined and covered anaerobic digesters. The fourth facility requested to cover an existing synthetically-lined lagoon.
