Minimum Control Measure
This fact sheet profiles the Pollution Prevention/Good Housekeeping for Municipal
Operations minimum control measure, one of six measures the operator of a Phase II
regulated small municipal separate storm sewer system (MS4) is required to include in its
storm water management program to meet the conditions of its National Pollutant Discharge
Elimination System (NPDES) permit. This fact sheet outlines the Phase II Final Rule
requirements and offers some general guidance on how to satisfy them. It is important to keep
in mind that the small MS4 operator has a great deal of flexibility in choosing exactly how to
satisfy the minimum control measure requirements.
Why Is Pollution Prevention/Good Housekeeping Necessary?
The Pollution Prevention/Good Housekeeping for municipal operations minimum control
measure is a key element of the small MS4 stormwater management program. This
measure requires the small MS4 operator to examine and subsequently alter their own actions
to help ensure a reduction in the amount and type of pollution that: (1) collects on streets,
parking lots, open spaces, and storage and vehicle maintenance areas and is discharged
into local waterways; and (2) results from actions such as environmentally damaging land
development and flood management practices or poor maintenance of storm sewer systems.
While this measure is meant primarily to improve or protect receiving water quality by altering
municipal or facility operations, it also can result in a cost savings for the small MS4 operator,
since proper and timely maintenance of storm sewer systems can help avoid repair costs from
damage caused by age and neglect.
What Is Required?
ecognizing the benefits of pollution prevention practices, the rule requires an operator of a
gulated small MS4 to:
Develop and implement an operation and maintenance program with the ultimate
goal of preventing or reducing pollutant runoff from municipal operations into the
storm sewer system;
Include employee training on how to incorporate pollution prevention/good
housekeeping techniques into municipal operations such as park and open
space maintenance, fleet and building maintenance, new construction and land
disturbances, and stormwater system maintenance. To minimize duplication of effort
and conserve resources, the MS4 operator can use training materials that are
available from EPA, their State or Tribe, or relevant organizations;
Determine the appropriate best management practices (BMPs) and measurable goals
for this minimum control measure. Some program implementation approaches,
BMPs (i.e., the program actions/activities), and measurable goals are suggested
below.

What Are Some Guidelines for Developing and
Implementing This Measure?
The intent of this control measure is to ensure that existing
municipal, State or Federal operations are performed
in ways that will minimize contamination of stormwater
discharges. EPA encourages the small MS4 operator to
consider the following components when developing their
program for this measure:
• Maintenance activities, maintenance schedules, and
long-term inspection procedures for structural and
non-structural controls to reduce floatables and other
pollutants discharged from the separate storm sewers;
• Controls for reducing or eliminating the discharge
of pollutants from areas such as roads and parking
lots, maintenance and storage yards (including
salt/sand storage and snow disposal areas), and waste
transfer stations. These controls could include
programs that promote recycling (to reduce litter),
minimize pesticide use, and ensure the proper
disposal of animal waste;
• Procedures for the proper disposal of waste
removed from separate storm sewer systems and
areas listed in the bullet above, including dredge
spoil, accumulated sediments, floatables, and other
debris; and
• Ways to ensure that new flood management
projects assess the impacts on water quality and
examine existing projects for incorporation of
additional water quality protection devices or
practices. EPA encourages coordination with flood
control managers for the purpose of identifying and
addressing environmental impacts from such
projects.
The effective performance of this control measure hinges on
the proper maintenance of the BMPs used, particularly for
the first two bullets above. For example, structural controls,
such as grates on outfalls to capture floatables, typically need
regular cleaning, while non-structural controls, such as
training materials and recycling programs, need periodic
updating.
What Are Appropriate Measurable Goals?
Measurable goals, which are required for each minimum
control measure, are meant to gauge permit compliance
and program effectiveness. The measurable goals, as well
as the BMPs, should consider the needs and characteristics
of the operator and the area served by its small MS4. The
measurable goals should be chosen using an integrated
approach that fully addresses the requirements and intent of
the minimum control measure.
EPA has developed a Measurable Goals Guidance for Phase
II MS4s that is designed to help program managers comply
with the requirement to develop measurable goals. The
guidance presents an approach for MS4 operators to develop
measurable goals as part of their stormwater management
plan. For example, an MS4 program goal might be to
incorporate the use of road salt alternatives for highway
deicing and reduce traditional road salt use by 50 percent in
the first year of the permit term.
