Commercial, Industrial, & Institutional Sites Residual Designation

In July 2013, Conservation Law Foundation, Natural Resources Defense Council, and American Rivers filed a petition to EPA Regions 1, 3 and 9 seeking EPA to make a determination that stormwater runoff from commercial, industrial and institutional sites contribute to violations of water quality standards and require NPDES permits. In March 2014, EPA released a response to the petition. Additional information is provided via the links below.
