3. Benefits of Strategic Goals Program n LOCAL POTW - reduced pollutant discharge to POTW - better working relationship with industries - less chance of NPDES violations - less time devoted to SIU permits n PLATERS - less burdensome permit requirements - less time and money devoted to environmental permits - technical assistance available

4. North Carolina Update n 4 participating POTWs: - Raleigh, Statesville, Charlotte, Gastonia n 8 metal finishers (3 site visits) n Additional incentives - Air quality, power companies, SBA Loans n Stakeholder meeting (June 29) n Industry Workshop (Fall)
