EPA Launches 2015 Green Infrastructure Webcast Series

The Green Infrastructure Permitting and Enforcement Series provides EPA and state permitting and enforcement professionals with a guide to integrating green infrastructure approaches into NPDES wet weather programs. The series consists of six factsheets and four supplements addressing general accountability considerations; CSOs; SSOs; stormwater; TMDLs; and water quality standards. The series includes sample language and case studies to illustrate the concepts discussed.

This supplement to Factsheet 5 summarizes two recent TMDLS that address flow, hydrology, and green infrastructure.

This supplement to Factsheet 2 provides an excerpt from the 2010 settlement with the Northeast Ohio Regional Sewer District (NEORSD) to address the flow of untreated sewage into Cleveland waterways and Lake Erie.

This supplement to Factsheet 2 summarizes the green infrastructure provisions in seven CSO consent decrees entered since 2003.

Water quality standards include designated uses, water quality criteria, and an antidegradation policy and implementation procedures. This factsheet describes how green infrastructure approaches can be considered as part of an Antidegradation Review or Use Attainability Analysis.

Many 303(d)-listed waters are impacted by changes in natural hydrology associated with urbanization. This factsheet describes how Total Maximum Daily Loads (TMDLs) and TMDL implementation plans (IPs) can address the hydrological factors that contribute to impairments by including green infrastructure.

Much of the aquatic ecosystem degradation associated with stormwater is caused by changes in discharge volumes, rates, and durations. This factsheet discusses how green infrastructure can be integrated into stormwater permits to maintain more natural flow regimes.
