A July 8 letter signed by WEF, American Rivers, Association of State and Interstate Water Pollution Control Administrators (ASIWPCA), National Association of Clean Water Agencies (NACWA), and Natural Resources Defense Council (NRDC) was sent to EPA offering perspectives on stormwater management policies including anticipated revisions to the nation’s Clean Water Act stormwater regulations. The organizations support EPA’s efforts to develop a well-informed and effective set of updated regulations that balance both environmental and economic considerations, particularly where these regulations create further incentives for green infrastructure-based approaches to stormwater pollution prevention, result in a more innovative and equitable regulatory program, foster the potential for watershed approaches to stormwater planning and control, and provide consistent direction and standards while allowing for local flexibility.

The letter outlined several areas for EPA’s consideration to improve stormwater practices:

· Performance standards for post-construction discharges from new development and redevelopment projects

· Revisions to MS4 boundaries and extensions of the permitting program to currently unregulated dischargers

· Retrofit programs to reduce the degree of imperviousness in already developed areas

· Application of stormwater regulations to combined sewersheds

This webcast, organized by the WEF Stormwater committee, covers the regulatory, technical, and research-based topics related to green infrastructure. In this webcast, the EPA provides an overview of the newly-released Green Infrastructure Strategy and discusses specific components related to this effort. Results  of study related to cost savings associated with the employment of low impact development stormwater measures at a variety of sites are presented by the University of New Hampshire Stormwater Center. Also, the economic, social, and environmental benefits in the Philadelphia area related to green infrastructure through a triple bottom line analysis are presented.

Water: Our Thirsty World

On June 7th, the Fallbrook Public Utility District dedicated the completion of a cost-saving solar panel project at its wastewater treatment plant. And with the combination of state rebates and government loans, FPUD is only paying half the cost needed to construct the facility. And just as important: FPUD will be saving around 70 percent of its SDG&E bills. [Read more]
