Field Manual
What is the IUM?
A manual intended for use as a technical reference.
A comprehensive, multi-objective ecosystem protection and
enhancement resource.
To be used by:
developers, planners, engineers, government officials and others involved
in land use planning, building site development and natural resource
conservation in both rural and urban communities as well as developing
areas.
Contains Standards & Specifications (materials, construction,
drawings) that describe BMPs (best management practices).
IUM BMPs - control non-point source pollution in communities and
developing areas
BMPs included:
Soil Erosion & Sediment Control
Stormwater Management
Special Area Protection
What is the IUM?
Dynamic document updated/expanded on a regular basis to include
additional standards & specifications.
Sets no policy, rules, regulations or restrictions.
Can be used by units of government as well as local, state or federal
agencies as a technical reference when developing rules and
regulations.
If adopted by reference in a regulatory program, the contents of the manual
have the force of law.
Example: General NPDES Permit No. ILR10
Part IV. Storm Water Pollution Prevention Plan

Replaces:
“Greenbook”
“Procedures and Standards for Urban Soil Erosion and Sedimentation Control
in Illinois,” Chapter 6 (“Procedures & Specifications”); Association of Illinois
Soil & Water Conservation Districts (AISWCD), 1981 (reprinted & revised
1988).
“Yellowbook”
“Standards and Specifications for Soil Erosion and Sediment Control;”
Published by Illinois EPA, 1987
Illinois Urban Manual, 1995
Developed by the United States Department of Agriculture – Natural Resources
Conservation Service (USDA-NRCS) for Illinois EPA; Updated 2002.
The IUM is actively being revised by a comprehensive, multiagency/organization partnership as part of a process known as the Illinois
Urban Manual Update Initiative.
Illinois Urban Manual Update Initiative
An ongoing revision coordinated by the Association of Illinois Soil & Water
Conservation Districts (AISWCD), who also provides ownership of the
manual.
Funding in large part provided by the Illinois Environmental Protection
Agency (IEPA) through Section 319 and 604b of the Clean Water Act.
The initiative to update the IUM is a cooperative, multi-agency effort.
The IUM Steering Committee (SC) and Technical Review Committee (TRC) are
actively tasked with the revision of the manual.
The SC is comprised of the following public agencies representing the entire State
of Illinois:
AISWCD, IEPA, Soil & Water Conservation Districts (SWCDs), Illinois Department of
Agriculture-Bureau of Land & Water Resources (IDA-BLWR), Illinois Department of
Transportation (IDOT), United States Army Corp of Engineers Chicago District (USACE),
and United States Department of Agriculture-Natural Resources Conservation Service
(USDA-NRCS).
The TRC is comprised of the above mentioned public agencies in addition to the
following public and private professionals:
Illinois Department of Natural Resources-Office of Water Resources (IDNR-OWR),
environmental consultants and engineers.

How do I use the IUM to address erosion and sediment control
on a construction site?
IUM (standard & specification) serves as a guide for proper selection,
installation and maintenance of soil erosion & sediment control best
management practices (bmps)
Selection – when developing the site plan (Storm Water Pollution
Prevention Plan (SWPPP) or equivalent)
Installation – when implementing a practice onsite
Maintenance – is the practice adequate to address site conditions? Is the
practice functioning properly? Is maintenance needed?
During an inspection, use IUM Standard to assess practice
performance onsite:
Is the practice being used properly?
Is the practice installed according to specifications?
Is the practice being maintained appropriately?
How do I use the IUM to address erosion and sediment control
on a construction site?
Practice Standard:
Definition
Introduction to what the standard is and helps the user discern if this is the
correct practice for their needs.
Purpose
Identifies the primary resource concern that the practice is designed to treat;
the reason the standard exists.
Conditions Where Practice Applies
Describes land use applicability, site conditions affecting the suitability or
function of the practice and situations where the practice may not be
applicable.
Criteria
Describes what has to be done in order to put standard practice on the ground;
basis for developing specifications;
Required limits of design; volume capacities; maximum velocities; tools/equipment
to be used; and safety measures.
How do I use the IUM to address erosion and sediment control
on a construction site?
Practice Standard:
Considerations
Only section of a standard that is not required; gives advice on what to do in
special circumstances; recommends measures that may increase
effectiveness beyond the minimums listed under “Criteria.”
Plans & Specifications
Lists items that must be planned & prepared for; items carry the same weight
as criteria.
Operation & Maintenance
Describes maintenance procedures to ensure proper performance of
practices; items carry the same weight as criteria.
Life span of the practice; frequency of inspection; frequency of maintenance
(cleaning out sediment, replacing materials)
References
Notes publications useful in planning or implementation as well as the original
source of technology used in the practice.

Field Manual for Inspection of Erosion & Sediment Control
Best Management Practices
A field manual, intended for use as a
technical reference by developers,
contractors, planners, engineers,
government officials and others involved in
field inspection of SESC Bmps.
Practices are taken directly from IUM.
Contains most commonly used practices
onsite.
Organized by Erosion Control, Sediment
