Introduction to the IUM 1 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. IUM BMPs - control non-point source pollution in communities and developing areas BMPs included: Soil Erosion & Sediment Control Stormwater Management Special Area Protection

Introduction to the IUM 1 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

Introduction to the IUM 1 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. Classic example…if using the 2002 printed copy of the IUM, you’d think Inlet Protection-Straw Bale Barrier is an appropriate BMP. According to the current IUM, it is not acceptable. (And you will have to replace it after I come to do an inspection…wasted time/money).

Introduction to the IUM 1 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.

IUM How-to… 2 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?

IUM How-to… 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.

IUM How-to… 2 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.
