Fact  Sheet
                Listening sessions and Stakeholder input: Stormwater
                Management Including Discharges from New
                Development and Redevelopment
     Summary

     The U.S. Environmental Protection Agency (EPA) is planning to open a public input
     period and hold listening sessions to inform a rulemaking to strengthen national
     stormwater regulations and to establish a comprehensive program to reduce stormwater
     discharges from new development and redevelopment.
     Background on Stormwater

     Developed sites, such as subdivisions
     and commercial shopping centers, can
     significantly alter the hydrology of a site
     and can have a negative impact on
     receiving waterbodies.

     Generally, as sites are developed, there
     is an increase in impervious areas
     where water cannot infiltrate into the
     ground, leading to increases in
     stormwater runoff volume. This
     additional stormwater volume, as well as
     the introduction of pollutants such as
     fertilizers, sediments and deposition of
     vehicle emissions contributes to
     increased stormwater impacts. Many of
     these developed areas are outside of
     currently regulated areas and are
     contributing to waterbody impairment.

     EPA requests input on ways to
     strengthen the stormwater program,
     including the promotion of practices that
     retain stormwater on-site through
     infiltration, evapotranspiration, or
     stormwater reuse to reduce these
     impacts nationwide. EPA is considering
     how to strengthen the municipal
     separate storm sewer system  (MS4)
     permit regulations, including expanding
                             the MS4 regulated area to include
                             rapidly developing areas and
                             establishing specific post construction
                             requirements for stormwater discharges
                             from new development and
                             redevelopment, both inside and outside
                             the MS4 boundary, that may be
                             contributing to waterbody impairments.

                             Proposed Regulatory Considerations

                             1. Expand the area subject to federal
                                stormwater regulations.
                             2. Establish specific requirements to
                                control stormwater discharges from
                                new development and
                                redevelopment.
                             3. Develop a single set of consistent
                                stormwater requirements for all
                                MS4s.
                             4. Require MS4s to address stormwater
                                discharges in areas of existing
                                development through retrofitting the
                                sewer system or drainage area with
                                improved stormwater control
                                measures.
                             5. Explore specific stormwater
                                provisions to protect sensitive areas.
