SWPPP Basics

Pre-Construction (GP#2 lingo: “prior to initiation of construction”) Engineer / Developer has: Prepared the SWPPP Transfer of Authority Published One Public Notice Filed Notice of Intent (NOI) with IDNR IDNR issues General Permit #2 Municipality reviews and approves All of this has been done before you are even involved. YOUR responsibility is to make sure what is in the SWPPP is being done as stated and know what to do if it is not being done as stated!

Transfer of Authority Developer as builder (includes lineal projects) No need for transfer of authority Developer sells to builder Two Choices Same Authorization Separate Authorization This is paperwork that needs to be included in the SWPPP – it is a decision of the developer (if a transfer of authority is needed).

Same v. Separate – Decision of Developer The developer either allows the builder to work under the developer’s permit “same authorization” or not. If not – the builder has to prepare his own SWPPP and go through all of the actions we are about to discuss.

Linear Projects - DOT Same or Separate? The rest of the day assumes you are in full control of the development project (commercial / lineal) and builders, in the case of residential development, are co-permittees (same authorization), rather than an individual building site or separate authorization (however the individual building site will be addressed today).

Individual Permit BMPs (Separate Authorization) Inspection expectations are the same on a smaller scale. SWPPP should call out what needs to be inspected and all practices should be maintained. Even if its part of a larger development. DISTRIBUTE ISWEP Individual Site Plan (look at front side.) SET ASIDE – will be using again during next presentation for SQR discussion.

SWPPP Narrative Maintenance Inspections Non-Stormwater Discharges Site Description Description of “Controls” Erosion, Sediment & Velocity Control (during construction) Stormwater Management (after construction) Other Controls Maintenance Inspections Non-Stormwater Discharges Contractors This is the order of narrative in GP#2 Guidance Document. It doesn’t necessarily have to be in this order; however, all the information must be provided within the SWPPP.

Time to break out the SWPPP!

Familiarize Yourself with SWPPP Narrative! 1. Cover Page YOU ARE ON THE FRONT PAGE of the SWPPP document  Notice it includes qualifications – ICCSPPI training meets the definition of qualified personnel. This is you!

Site Description 2. Site Description Notice Project Site – acres being disturbed and phases of construction. Where are the boundaries. The stormwater permit ONLY covers the area described in the SWPPP.

3. Sequence of Activities 1 - 20 Sequence of activities – this does not have dates associated with the activities. Some include dates. You’ll want to note the KEY INFO located in the appendix: drainage patter, approximate slopes after major grading; area of soil disturbance. Appendix Content – KEY INFO

4. Discharge Points 5. Potential Pollutants Location of structural controls; non-structural controls; areas to be stabilized; surface drainage ways and stormwater discharge locations. NOTE discharge points – this will come in handy when inspecting KNOWN outfalls. 5. Potential Pollutants

6. Potential Areas of Stormwater Contamination THERE ARE many potential pollutants related to construction – its not all about soil erosion and control – note the potential sources of pollution and where they may originate. There needs to be a plan in place to contain if there is a spill of a hazardous material? We’ll go into that when we discuss best management practices in detail – which is the next presentation. 6. Potential Areas of Stormwater Contamination

Part 2 - CONTROLS Skip for now

Part 4 INSPECTIONS, Page 9 This is you! Detention basin is the primary post-construction control. Qualified Personnel; inspection should be conducted every 7 days and known inspection points versus corrective action points identified (might not be listed in Part 4)

YOUR RESPONSIBILITY: Note deficiencies on inspection form. Communicate issues with Permit Holder. Leave the HOW to remedy corrective actions needed to Permit Holder. If something isn’t working another control may be needed. Note on inspection form; communicate with permit holder. You may volunteer what might work; however, prevent being put in the position where they could come and say – well you told us to do this and its not working.

14 / 21 Day Rule If construction activity is NOT planned to occur in a disturbed area for at least 21 days, that area shall be stabilized by temporary seeding within 14 days. May INCLUDE Topsoil Stockpiles. (October 2017 – may change to 0/14 day rule) Soon to become 0 / 14 day rule, most likely after October 2017.

Non-Stormwater Discharges Part 5 Maintenance as identified during construction and corrected by contractor I – corrective action. There are three levels of corrective action – one of those, if it isn’t causing a major problem, is within seven days. A few corrective actions require immediate attention (sediment laden water making its way to surface water would be one scenario). Part 5 provides guidance on Maintenance of Controls. Non-stormwater discharges are also identified in the SWPPP. Non-Stormwater Discharges

Implementation & Certification Non-Stormwater Discharges Continued Implementation & Certification Two non-stormwater discharges cross over to SWPPP enforcement – which two? D. and E. Part 7 – determines who is ultimately responsible for the implementation and maintenance of all measures identified in the SWPPP. It also notes the need for Contractor and Sub-Contractor Certification – again PAPERWORK you need to ensure is in order! It also requires that contract add starting dates for MAJOR activities – this needs to be complete as soon as it commences.

C. Certification Certification continued Retention of records All records must be kept for a period of AT LEAST THREE YEARS from the date that the site is finally stabilized!

Contractor Certification is Serious Business! Grading Silt Fence Seeding Underground Utility Paving OTHER A NOTE ON CERTIFICATION STATEMENTS - Have participants brainstorm OTHER contractors (trades, suppliers, etc.) Who DOESN”T need to sign the Contractor Certification?

“I certify under penalty of law…” “You are encouraged to advise EACH OF YOUR EMPLOYEES WORKING ON THIS PROJECT of the requirements of the SWPPP. “I certify under penalty of law…” Suggest easy way for training – perhaps quick youtbe video that can be shared for contractor employee training. Others? Include as part of safety meetings?

Paperwork required to complete the SWPPP; reference documents to ensure controls are installed, maintained and removed as specified.

First Inspection Point IS PAPERWORK IN ORDER? NOI GP#2 Owners Certification THIS HAS BEEN DONE or should have been done and should be included as part of the SWPPP. If these documents are not included – it’s your first corrective action identified!

NOI What a NOI looks like – key areas to cover. Does timetable match SWPPP document?

General Permit #2 GP#2 – One Page Document provided by DNR that give the contractor authorization to discharge stormwater to waters of the state.

Proof of Publication Proof of publication, as a record to SWPPP.

Owner’s Certification & Notification Original included on NOI Owner Certification included on NOI – additional owners or new owners need to sign this as well!

SWPPP Site Plan Must be accessible within 2 hours upon request from Enforcement Official (EPA/DNR/Jurisdiction). Does not have to be a “paper” SWPPP! HAVE PLAN IN HAND AND PARTICIPANTS ARE REVIEWING AS YOU GO OVER SITE PLAN. Start with Cover Page – Sheet index and how it relates to erosion and sediment control Phases of construction (or at least there SHOULD be at least one SHEET per Phase – due to different BMPs needed at different stages of construction) Other phases, while not related to E&SC have practices that need to be inspected for correct installation, maintenance and, if needed, removal (i.e. Detention Basin Sheets)

Special Attention to: Mention of SUDAS – that is reference for design standards and specifications and Sheet Index. Division 9 and C1.1 – C2.5. SUDAS REFERENCE

STANDARD CONTROLS Administrative Control (A) Good Housekeeping (G) Erosion Control (E) Sediment Control (S) Velocity Control (V) Post Construction (P) SWPPP Controls: A – Z = 26 controls included in SWPPP. The controls fall into one of six categories: Administrative Control (A); Good Housekeeping (G); Erosion Control (E); Sediment Control (S); Velocity Control (V); and Post Construction (P). For this exercise we focus on A – V; next presentation focuses on Post-Construction Controls.
