Water: Green Infrastructure
What is EPA Doing to Support Green Infrastructure?
Since 2007, EPA has actively engaged with public and private partners to promote the implementation of sustainable stormwater infrastructure. EPA renewed its commitment to green infrastructure in April of 2011 with the release of an updated Strategic Agenda and the initiation of 10 community partnerships. EPA recognizes local practitioners as the leaders in the implementation of multi-functional green infrastructure and seeks to foster continued innovation through information exchange and the removal of key barriers.

The agenda identifies five key objectives that the EPA will pursue to encourage the implementation of green infrastructure:
- Community partnerships;
- Clarifying green infrastructure within the regulatory and enforcement contexts;
- Outreach and information exchange;
- Financing; and
- Tool development and capacity building.

2011 Community Partners

Memorandum, Achieving Water Quality Through Integrated Municipal Stormwater and Wastewater Plans (PDF) (3 pp, 1.1MB) - In October 2011, EPA’s Office of Water (OW) and Office of Enforcement and Compliance Assurance (OECA) issued a joint memo encouraging EPA regions to assist their state and local partners in pursuing an integrated planning approach to Clean Water Act waste and stormwater obligations. The memo identifies green infrastructure as one example of a comprehensive solution that can improve water quality while supporting other quality-of-life attributes that enhance the vitality of communities.
Memorandum, Protecting Water Quality with Green Infrastructure in EPA Water Permitting and Enforcement Programs (PDF) (6 pp, 215K) - In April 2011, EPA’s OW and OECA issued a joint memo supporting the use of green infrastructure. The memo reaffirms the commitment of both offices to work with interested communities on incorporating green infrastructure into stormwater permits and remedies for non-compliance with the Clean Water Act (such as Combined Sewer Overflow (CSO) consent decrees).
Memorandum, Clarification on Which Stormwater Infiltration Practices/Technologies have the Potential to be Regulated as "Class V" Wells by the Underground Injection Control (UIC) Program (PDF) (6 pp, 215K) - In June 2008, EPA issued a memo reaffirming the use of green infrastructure approaches (including infiltration practices that are classified as 'green') for managing stormwater, and providing an overview of UIC program requirements for stormwater infiltration practices that are classified as Class V wells. The memo is supported by a guide describing the major types of stormwater infiltration practices and explaining which practices are generally considered class V wells.
Memorandum, Using Green Infrastructure to Protect Water Quality in Stormwater, CSO, Nonpoint Source and other Water Programs (PDF) (2 pp, 156K) - In March, 2007, Benjamin Grumbles, EPA's Assistant Administrator for Water, issued this memo to promote green infrastructure as a viable stormwater management solution.
