2. 1 Introduction to the IUM 2How-to… 3 Field Manual

3.  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 1

4.  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 1

5.  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, multi- agency/organization partnership as part of a process known as the Illinois Urban Manual Update Initiative. 1

6.  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. 1

17.  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? 2

18. 2  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.

19.  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. 2
