The EPA discontinued this FY 2017-2019 Preventing Animal Waste from Contaminating Surface and Ground Water NCI at the end of FY 2018, one year ahead of the end of the current NCI cycle, and returned work in this area to the EPA’s core compliance assurance program. Enforcement opportunities under this NCI were limited because of court rulings that narrowed the universe of facilities required to be permitted. In addition, most enforcement in this area is administrative, not judicial. Thus, addressing the environmental problems arising from animal waste is more appropriate as part of the core compliance assurance program. As part of the core program, EPA regions, in collaboration with authorized state programs, will continue to conduct inspections and enforcement actions to address serious violations in this area, focusing on the Strategic Plan goal of reducing water quality impairment.
