Table of Contents ➢ Purpose of SWPPP training ➢ What is pollution? ➢ What is erosion? ➢ What is sediment? ➢ Benefits of prevention measures ➢ Required posting at jobsites ➢ Construction Sequencing ➢ Reporting and documentation ➢ Maintenance during construction ➢ Key points ➢ Pictures ➢ Fines $$$$$
- 3. Purpose of SWPPP Training ➢ IT’S THE LAW !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ⚫ Enforced by the Federal EPA via Clean Water Act of 1988, National Pollution Discharge Elimination System (NPDES) 1990 ⚫ Enforced by state and local administrations having jurisdiction ➢ The Stormwater Pollution Prevention Plan (SWPPP) is designed to eliminate pollution from leaving the construction site. ➢ To eliminate pollution of the U.S. waterways ➢ To ensure that all individuals understand the importance of Management Practices (MPs) on construction sites.
- 4. “Trained Individual” ➢Required by law to be trained in Stormwater Compliance ➢Must be familiar with SWPPP and have access to it ➢Must understand the purpose of BMPs ➢Must have authority to make corrections ➢Must be present at pre-construction meeting ➢Should not be the excavating contractor ➢Should be available onsite throughout the project ➢Must know what BMPs are included in the SWPPP, the sequence of installation, proper maintenance of each, and be able to evaluate their effectiveness ➢Must be able to identify BMPs that are failing ➢Must be available until the site can be officially closed
- 5. Trained Individual Local Compliance ➢ Proof of Stormwater training must be furnished to the Stormwater Office for verification. ➢ Familiarity with the SWPPP ➢ Familiarity with the process, in place nationally since 1996, locally since 2006
- 6. Self Inspection Training is REQUIRED on all sites issued a Stop Work Order ➢ The site owner and at least one additional person who will be responsible for implementing the SWPPP must complete Self Inspection training if a Stop Work Order has been issued. This training must be complete before the order may be lifted.
- 7. Repeat Violations ➢ At least one person who will be responsible for implementing and documenting the SWPPP must complete Self Inspection training or submit proof of some other type of training. ➢ Stated in the Stormwater Ordinance
- 8. What is Pollution? ➢ “The action of polluting especially by environmental contamination with man-made waste” ➢ “The act of contaminating or polluting; including (either intentionally or accidentally) unwanted substances or factors” ➢ “undesirable state of natural environment being contaminated with harmful substances as a consequence of human activities” Construction Site Pollution ➢ Waste or debris is generated by every person doing work on a construction site. ➢ If the waste or debris is not contained and disposed of properly, it becomes pollution. ➢ Good Housekeeping practices will reduce the potential for pollution.
- 9. What is Erosion? ➢ Erosion: Is the process in which, by the action of wind or water, soil particles are displaced or transported What are the types of erosion? ➢ Splash: Raindrop impact, dispersal and mobilization of soil particles ➢ Sheet: Saturated soils, soil particles entrained in run-off water, uniform removal ➢ Gully: Concentrated flow, head cutting, down cutting ➢ Stream Bank: Natural drainage patterns, toe cutting, bank sloughing The BEST practices to prevent splash erosion are Preservation of Existing Vegetation and Stabilization
- 10. What is Sediment? ➢ Sediment: eroded material suspended in water or in the air. Sediment is the #1 pollutant of waterways. Dust IS erosion. ➢ Sedimentation: the deposit of eroded materials ➢ When erosion occurs, small particles become suspended in water or air and sediment is transported down-stream or down wind. ➢ The purpose of stormwater pollution prevention is to minimize the opportunity for EROSION to occur, thus minimizing the possibility of SEDIMENT leaving the jobsite ➢ Most concentrated sedimentation comes from construction, which can exceed 100 times that from agriculture.
- 11. What can be done to control sedimentation? These simple devices can be used during construction to greatly reduce erosion and minimize sedimentation. ➢ Temporary and permanent stabilization ➢ Sediment barrier or proper border ➢ Stone construction entrance ➢ Grass covered drainage ditches
- 12. Benefits of Prevention Measures? ➢ Reduce rainfall impacts ➢ Reduce surface water velocities ➢ Assist with stormwater infiltration ➢ Reduce and control sediment ➢ Eliminate off-site pollution Protection of Soils ➢ Protection of soils can be established with vegetation. However, other types of cover materials such as mulches, erosion matting, erosion blankets, must be used until vegetation is established to minimize splash and sheet flow erosion. ➢ Effectiveness of soil protection is dependent on both the type and density of the specific cover material being utilized.
- 13. Overriding Goal Protect the quality of U.S. waterways by reducing the discharge of sediment, oil and chemicals into storm drains, surface water and groundwater.
- 14. Pre Construction Meeting ➢ At minimum, the person designated as the Trained Individual, responsible for implementing the SWPPP ➢ It’s important that we be notified if this changes, since reports are sent via email ➢ If at all possible, the owner should also be present. This allows us to discuss their Post Construction Agreement and responsibilities ➢ Go over a check list with typical problems, site specific BMP list, change orders, etc. ➢ This meeting helps clearly identify who has what responsibility and helps prevent misunderstanding between you and your client
- 15. Understanding the Process ➢ The period of time between building completion and filing a Notice of Termination (N.O.T.) is often misunderstood. ➢ A site may not be closed with a N.O.T. until all areas have at least 70% established vegetation. ➢ Until this time, the N.O.I. must remain posted and self inspections must continue every week and within 24 hours of every 1/2 “ of rainfall. ➢ This usually extends beyond receiving your Certificate of Occupancy. ➢ This cannot be handed off to the owner, unless they are trained in stormwater management. ➢ Pre-construction meetings address this from the onset. ➢ You need to verify that a SWPPP was submitted by the owner, and approved.
- 16. Required Job Postings ➢ Notice of Intent (NOI) ➢ Descriptionof the project ➢ General Contractor’s local contact name and number ➢ Location of SWPPP ➢ Any other special conditions or required permits All contained in a waterproof display case at construction entrance: Additional Postings: ➢ Stormwater Pollution Prevention Sign ➢ Field Office sign posted on trailer ➢ Spill Containment System location ➢ Concrete Washout sign Inside the Job Trailer: ➢ Original SWPPP ➢ WorkingSWPPP drawing ➢ Self Inspection reports
- 17. Project Management Log/3 Ring Binder ➢ IDEM documents ➢ Local permit ➢ Self inspection reports ➢ Municipal and IDEM reports ➢ Hauling records for borrow and fill ➢ Documentation of any spills, reporting and cleanup
- 18. Construction Sequencing ➢ Phase I installation of the following: ⚫ Construction entrance (s) ⚫ Silt fence or other barrier BMP ⚫ …BEFORE any major grading ⚫ Check dams ⚫ Diversion drains ⚫ Inlet protection ⚫ Swales ⚫ Detention pond, sediment basins and traps ⚫ Concrete washout area per SWPPP ⚫ Vehicle maintenance / fueling area ⚫ Stoned storage / laydown area ➢ Phase II ⚫ Additional phased BMPs per SWPPP ⚫ Temporary stabilization (any area which will not be worked for 7 days or more) ⚫ Permanent stabilization Contact IDEM and Local Authority 48 hours prior to beginning grading activities.
- 19. Reporting and Documentation ➢ Reporting ⚫ Reporting submitted to Owner, PM & Stormwater office ⚫ Weekly inspection summary ⚫ Rainfall (1/2”) Event inspection summary (prior or after) ⚫ EPA, State, or Local jurisdiction inspections ⚫ Spill report form ➢ Documentation ⚫ Site stabilization ⚫ Contractor and subcontractor certifications ⚫ Notice of Termination (NOT) ⚫ E&S Plan All SWPPP records must be maintained a minimum of three years after Notice of Termination.
- 20. BMP Installation ➢ Check dams ⚫ Never with silt fence ⚫ Straw bales must be entrenched and staked ⚫ Lower in center.. SMILE ⚫ Smaller stone on flow side as filter
- 21. Maintenance During Construction ➢ New or major grading will be recorded in SWPPP binder- Site Stabilization ➢ Repairs, discharges, modifications and alterations should be recorded daily on the Working SWPPP ➢ Inspection reports document repairs, discharges, effectiveness, and should be recorded in the SWPPP binder ➢ Photographic documentation should be taken of the site conditions and used to document the effectiveness of, alterations to, and repairs to any BMPs ➢ Transition from temporary to permanent stabilization is critical ➢ Reporting the failure of a BMP is the responsibility of all employees on the jobsite…this means YOU!!!
- 22. Additional Measures Needed ➢ If BMPs are failing, the designer must be notified. It is the designers responsibility to find corrective MPs. They are chosen based on contributing drainage areas. ➢ Owner should also be notified of problems ➢ Problems must be clearly identified, including exact location and observations ➢ Suggestions should be recorded. Often, the person on site can be instrumental to helping the designer find solutions ➢ Problems and corrections must be noted on self inspection report
- 23. Winterization ➢ In planning when to disturb different areas, keep in mind, any areas that will be dormant for 7 days or more MUST have stabilization initiated. At the very least, this requires a straw mulch application. ➢ This includes areas where permanent stabilization did not occur in time for winter. All disturbed ground must have straw mulch applied, at a minimum, over the winter months. ➢ Preserving the existing vegetation as long as possible can save you work and money.
- 24. Key Points ➢ IT IS THE LAW !!!!!!!!!!!!!!!!!! ➢ Construction Sites are active, and SWPPP will change every day. Documentation is required. ➢ It is the responsibility of every person on the jobsite to report any changes that are made, or need to be made, to the erosion and sediment controls ➢ All erosion and sediment controls are inspected weekly and prior/after every ½” of rain, or thaw ➢ Any discharge of sediment from the jobsite must be reported immediately! ➢ Vehicle track-out (mud from tires) is pollution !! ➢ Employees should know the location of the SWPPP
- 25. Jobsite Pollution ➢ Waste and debris that is not properly controlled and disposed of is pollution!
- 26. Jobsite Pollution ➢ Waste and debris that is not properly controlled and disposed of is pollution!
- 27. Jobsite Pollution ➢ Fuel and oil based products that are not contained or properly disposed of are pollution!
- 28. Spill Containment ➢ The spill containment kit shall be used if at any time oil or fuel based products are spilled or leak from their container. ➢ Pollution such as this must be reported to the Bureau of Water Quality and contained immediately!!! Spill kits are required if onsite refueling will occur.
- 29. ➢ Proper storage of hazardous materials will eliminate the opportunity for pollution. ➢ Secondary containment is a valuable tool for preventing spills in the first place. Jobsite Pollution
- 30. Display Case and Signage Must remain posted until Notice of Termination is filed.
- 31. SWPPP Site Plan ➢ The SWPPP is a living document that is updated on a daily basis. The SWPPP should be located at the Field Office.
- 32. Silt Fence & Sediment Barrier Examples (BAD!)
- 33. Silt Fence & Sediment Barrier Examples (BAD!) Not staked Not Staked Not maintained
- 34. Inlet Protection It is NEVER acceptable to poke holes in inlet protection to allow for drainage. It is NEVER acceptable to remove inlet protection to allow for drainage. Fabric beneath the grate is not an acceptable protection. Properly installed inlet protection will allow for overflow in case of heavy rain.
- 35. Silt Fence and Sediment Barrier Examples (Good!)
- 36. Silt Fence and Sediment Barrier Examples (Good!)
- 37. Silt Fence Maintenance ➢ Must be trenched ➢ Must be installed facing the proper direction ➢ Must have properly wrapped connections ➢ Inspect within 24 hours of a rain event (before or after), or at least once every 7 days ➢ Remove deposited sediment when it is causing the fabric to bulge or when it reaches one-third the height of the fence at its lowest point. When contributing drainage area has been stabilized, remove the fence and sediment deposits, grade the site to blend with the surrounding area, and stabilize.
- 38. Inlet Protection (Bad) ➢ Frames inadequate ➢ Not trenched ➢ Not reinforced ➢ Not maintained
- 39. ➢ Frames properly built ➢ Properly trenched ➢ Reinforced filter fabric ➢ Anchored ➢ Should allow for overflow in case of heavy rainfall Inlet Protection (Good) Allow for overflow
- 41. Dewatering (Bad) ➢ Dewatering must be done into a filtered bag or sediment basin Too Full !!! Not over bare ground
- 43. Dewatering goal, Clear water = All dewatering now requires prior approval by the Stormwater Office. This includes demolition. Sites containing contaminants other than sediment may require water testing.
- 44. Seeding and Stabilization (Bad) ➢ Lack of stabilization has allowed washout of soils ➢ Areas have remained idle for more than 7 days ➢ Mulch or proper matting installation could have prevented most of this erosion
- 45. Not an Anchor Not Anchored
- 46. Rocks ARE NOT Anchors Complete failure of matting Due to improper preparation and installation
- 47. Seeding and Stabilization (Good) ➢ Areas have received final grade while other areas are still under construction ➢ Pond and channel slopes have received blanket to combat erosion ➢ Sod installed in concentrated flow areas Sod installation Sod in high flow area
- 48. Concrete Wash Out (Bad) ➢ Concrete wash out is pollution! ➢ Concrete washouts should be provided for delivery trucks. ➢ Same effect on ground water as Draino No Hard Fill
- 49. Concrete Wash Out (Good) ➢ Pit lined with continuous 10 mil liner ➢ Stormwater run off protected from contamination
- 51. Construction Entrance ➢ Most common violation ➢ Geotextile underlayment required ➢ Large aggregate, typically #2, to help knock mud from tires before leaving the site ➢ Wheel wash stations ➢ Maintenance: ⚫ Inspect daily ⚫ Reshape pad as needed for drainage and runoff control ⚫ Top dress with clean aggregate as needed ⚫ Immediately remove mud tracked onto public roads ⚫ Stone may need to be completely replaced. ⚫ Flushing should only be used if water can be diverted to a sediment trap or basin
- 52. Between the Certificate of Occupancy & the Notice of Termination ➢ Plan ahead for this, in estimating and contract preparation ➢ Your responsibility does not end when the business opens or the owner moves in. ➢ A site cannot be closed until it is fully completed and vegetation is permanently established ➢ Self inspections must continue ➢ Maintenance of BMPs must continue ➢ Posting must remain
- 53. Final Inspection ➢ A final inspection will be completed by the local authority. ➢ All temporary MPs must be removed. ➢ As builts must be submitted ➢ Vegetation must be established to 70%. (This means, anywhere on site, as you look directly down, you should see grass and not soil.) ➢ A Notice of Termination may then be filed with IDEM, which will permanently close the site and terminate your responsibility.
- 54. Not Ready
- 55. Established
- 56. Smaller sites, new as of 2017 ➢ All sites with new construction now require a Stormwater Permit ➢ Given to you at the Building Office when you apply for a permit ➢ Your responsibility to return that to me ➢ You must make “Every reasonable effort to minimize pollutants” from leaving your site
- 57. How? ➢ Protect inlets on or downstream from your site ➢ Clean up tracking, at minimum, daily ➢ Keep dumpster covered when not in use (weekends, heavy winds) ➢ Use sediment barriers when needed (silt fence, silt socks, straw wattles) ⚫ If your site is on a slope ⚫ Behind the sidewalk ➢ Dewater only clear water to the street ➢ Sediment water should be directed to vegetation ➢ Provide a contained concrete washout
- 58. Citizens can initiate civil suits against: ➢ An individual person ➢ A construction company ➢ The U.S. or any other government entity ➢ The EPA itself
- 59. Compliance ➢ Avoid costly Stop Work Orders In many jurisdictions, violations causing an immediate danger to the environment do not require prior notice for Stop Work Orders to be issued.
- 60. Compliance ➢ And even more costly fines of up to $54,000 per day from IDEM or EPA.
- 61. EPA Administrative Fines ➢ In 2021, assessed $1.05 Billion in penalties ➢ EPA Non-Compliance Violations include • No permit • No SWPPP • No inspection records • No amendments to SWPPP
