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.
