How-to…
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

What is the IUM?
 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.
