Part I: Site Description, describe the project

Describe the project location; include latitude and longitude, section, town, and range.
Describe the nature of the construction activity or demolition work.
Describe the intended sequence of major activities which disturb soils for major portions of the site (e.g. clearing, grubbing, excavation, grading, on-site or off-site stockpiling of soils, on-site or off-site storage of materials).
Part I: Site Description, the total area, soils and MS4 permittees

Enter the total area of the construction site, estimated, in acres.
Enter the total area of the site estimated to be disturbed by excavation, grading or other activities, in acres.
Determine an estimate of the runoff coefficient of the site after construction activities are completed.
Provide the existing information describing the potential erosivity of the soil at discharge locations at the project site.
Mark Yes or No: the Erosion and Sediment Control Plan (Graphic Plan) is included in the contract.
List all soils found within project boundaries; include map until name, slope information, and erosivity.
List all MS4 permittees in the area of this project. For sites discharging to an MS4, a separate map identifying the location of the construction site and the location where the MS4 discharges to surface water must be included.
Part II: Waters of the US, receiving waters and wetlands
Natural buffers

For any storm water discharges from construction activities within 50 feet of a Waters of the United States, except for activities for water-dependent structures authorized by a Section 404 permit, the following shall apply: (i) A 50-foot undisturbed natural buffer between the construction activity and the Waters of the United States has been provided: mark Yes or No; and/or
(ii) Additional erosion and sediment controls within that area has been provided: mark Yes or No; and Describe:

Guidance on preparing each section of BDE 2342 (Storm Water Pollution Prevention Plan) is found in Chapter 41 of the IDOT Bureau of Design and Environment (BDE) Manual, please consult this chapter during SWPPP preparation. Please note that the Illinois Environmental Protection Agency (IEPA) has 30 days to review the Notice of Intent (NOI) prior to project approval and any deficiencies can result in construction delays.
In the following table are commonly used chemicals/practices used on a construction site. If other chemicals that could contribute a violation of a Water Quality Standard, add as needed.
If no boxes are checked in Table 1, check the box: There are no chemicals on site that will exceed a Water Quality Standards if spilled.
If any boxes are checked in Table 1, check the box: There are chemicals on site that if spilled could potentially cause an exceedance of a Water Quality Standard.
Does the project area have any 303(d) impaired waterways with the following impairments? suspended solids turbidity, and or siltation. Mark Yes or No.
If yes, list the name(s) of the listed water body and the impairment(s).
Does the project include any receiving waters with a TMDL for sediment, total suspended solids, turbidity or siltation? Mark Yes or No.
If yes, list TMDL waterbodies and describe the associated TMDL.
Erosion Control: place a check by each practice that will be utilized on the project, add additional practices as needed.
Sediment Control: the following sediment control devices will be implemented on this project.
Structural Practices: provide a description of structural practices that will be implemented.
Will dewatering be required for this project? Mark Yes or No.
In some instances, an additional practice from a local ordinance may be included in the project. If so, describe it (Note: the Department is not subject to local ordinances).
Describe procedures to maintain in good and effective operating conditions.
Common questions about Form BDE 2342
Is there a deadline?
Stabilization efforts must be initiated within 1 working day of cessation of construction activity and completed within 14 days. Areas must be stabilized if they will not be disturbed for at least 14 calendar days.
Is there a penalty?
There are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations. Failure to comply with any provisions of this Storm Water Pollution Prevention Plan will result in the implementation of a National Pollutant Discharge Elimination System/Erosion and Sediment Control Deficiency Deduction against the Contractor and/or penalties under the Permit ILR10 which could be passed on to the contractor.
