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 Best Management Practices (BMPs) on construction sites.

4 “Trained Individual” 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

5 Construction Site Pollution
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.

6 What are the types of erosion?
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 Rill: Increase topographic relief, higher run-off velocities, soil incision Gully: Concentrated flow, head cutting, down cutting Stream Bank: Natural drainage patterns, toe cutting, bank sloughing

7 What is Sediment? Sediment: eroded material suspended in water or in the air. Sediment is the #1 pollutant of waterways. 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.

8 Temporary and permanent stabilization Sediment fence or proper border
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 fence or proper border Stone construction entrance Grass covered drainage ditches

9 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 dependant on both the type and density of the specific cover material being utilized.

10 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.

11 All contained in a waterproof display case at construction entrance:
Required Job Postings All contained in a waterproof display case at construction entrance: NPDES Permit Notice of Intent (NOI) Description of the project General Contractor’s local contact name and number Location of SWPPP Any other special conditions or required permits Additional Postings: Stormwater Pollution Prevention Sign Field Office sign posted on trailer Spill Containment System location Inside the Job Trailer: Original SWPPP Working SWPPP drawing

12 Construction Sequencing
Contact IDEM and Local Authority 48 hours prior to beginning grading activities. 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 15 days or more) Permanent stabilization

13 Reporting and Documentation
Reporting submitted to Owner and PM Weekly inspection summary Rainfall (1/2”) Event inspection summary 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.

14 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!!!

15 Additional Measures Needed
If BMPs are failing, the designer must be notified. It is the designers responsibility to find corrective BMPs 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

16 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 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

17 Jobsite Pollution Waste and debris that is not properly controlled and disposed of is pollution!

18 Jobsite Pollution Waste and debris that is not properly controlled and disposed of is pollution!

19 Jobsite Pollution Fuel and oil based products that are not contained or properly disposed of are pollution!

20 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!!!

21 Jobsite Pollution Proper storage of hazardous materials will eliminate the opportunity for pollution. Secondary containment is a valuable tool for preventing spills in the first place.

22 Display Case and Signage

23 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.

24 Silt Fence Examples (BAD!)

25 Silt Fence Examples (Good!)

26 Silt Fence Maintenance
Must be trenched Must be installed facing the proper direction Must have properly wrapped connections Remove sedimentation when it reaches 1/3 the height of the fence Must be repaired as needed

27 Inlet Protection (Bad)
Frames inadequate Not trenched Not reinforced Not maintained

28 Inlet Protection (Good)
Frames properly built Properly trenched Reinforced filter fabric Anchored Should allow for overflow in case of heavy rainfall

29 Seeding and Stabilization (Bad)
Lack of stabilization has allowed washout of soils Areas have remained idle for more than 15 days Mulch or matting could have prevented most of this erosion

30 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

31 Concrete Wash Out (Bad)
Concrete wash out is pollution! Concrete washouts should be provided for delivery trucks.

32 Concrete Wash Out (Good)
Pit lined with continuous 10 mil liner Stormwater run off protected from contamination

33 Construction Entrance
Good Bad

34 Citizens can initiate civil suits against:
An individual person A construction company The U.S. or any other government entity The EPA itself

35 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.

36 Compliance And even more costly fines of up to $25,000 per day from IDEM

37 EPA Administrative Fines
Currently $260 Million fines against builders in litigation EPA Non-Compliance Violations include No permit No SWPPP No inspection records No amendments to SWPPP
