EPA is releasing a report that examines the operation and maintenance practices of several green infrastructure projects funded by the Clean Water State Revolving Fund under the American Recovery and Reinvestment Act and identifies trends and common elements shared by the various projects. The report provides information to communities and operators on funding programs to help ensure that green infrastructure projects are operated and maintained to optimize long-term performance and effectiveness.

EPA has released a series of six fact sheets on incorporating green infrastructure measures into National Pollutant Discharge Elimination System wet weather programs. The series builds upon existing EPA authority, guidance and agreements to describe how EPA and state permitting and enforcement professionals can work with permittees to include green infrastructure measures as part of control programs. The six fact sheets and four supplements address stormwater permits, total maximum daily loads, combined sewer overflow long-term control plans, and enforcement actions.
