2Purpose of SWPPP TrainingITS THE LAW !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Enforced by the Federal EPA via Clean Water Act of 1988, National Pollution Discharge Elimination System (NPDES) 1990Enforced by state and local administrations having jurisdictionThe Stormwater Pollution Prevention Plan (SWPPP) is designed to eliminate pollution from leaving the construction site.To eliminate pollution of the U.S. waterwaysTo ensure that all individuals understand the importance of Best Management Practices (BMPs) on construction sites.3Trained IndividualMust be familiar with SWPPP and have access to itMust understand the purpose of BMPsMust have authority to make correctionsMust be present at pre-construction meetingShould not be the excavating contractorShould be available onsite throughout the projectMust know what BMPs are included in the SWPPP, the sequence of installation, proper maintenance of each, and be able to evaluate their effectivenessMust be able to identify BMPs that are failing

4What is Pollution?The action of polluting especially by environmental contamination with man-made wasteThe act of contaminating or polluting; including (either intentionally or accidentally) unwanted substances or factorsundesirable state of natural environment being contaminated with harmful substances as a consequence of human activitiesConstruction Site PollutionWaste 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.5What is Erosion?Erosion: Is the process in which, by the action of wind or water, soil particles are displaced or transportedWhat are the types of erosion?Splash: Raindrop impact, dispersal and mobilization of soil particlesSheet: Saturated soils, soil particles entrained in run-off water, uniform removalRill: Increase topographic relief, higher run-off velocities, soil incisionGully: Concentrated flow, head cutting, down cuttingStream Bank: Natural drainage patterns, toe cutting, bank sloughing

6What is Sediment?Sediment: eroded material suspended in water or in the air. Sediment is the #1 pollutant of waterways. Sedimentation: the deposit of eroded materialsWhen 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 jobsiteMost concentrated sedimentation comes from construction, which can exceed 100 times that from agriculture.

7What can be done to control sedimentation?

These simple devices can be used during construction to greatly reduce erosion and minimize sedimentation. Temporary and permanent stabilizationSediment fence or proper borderStone construction entranceGrass covered drainage ditches8Benefits of Prevention Measures?Reduce rainfall impactsReduce surface water velocitiesAssist with stormwater infiltrationReduce and control sedimentEliminate off-site pollutionProtection of SoilsProtection 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. 9

Overriding GoalProtect the quality of U.S. waterways by reducing the discharge of sediment, oil and chemicals into storm drains, surface water and groundwater.

All SWPPP records must be maintained a minimum of three years after Notice of Termination. 13Maintenance During ConstructionNew or major grading will be recorded in SWPPP binder-Site StabilizationRepairs, discharges, modifications and alterations should be recorded daily on the Working SWPPPInspection reports document repairs, discharges, effectiveness, and should be recorded in the SWPPP binderPhotographic documentation should be taken of the site conditions and used to document the effectiveness of, alterations to, and repairs to any BMPsTransition from temporary to permanent stabilization is criticalReporting the failure of a BMP is the responsibility of all employees on the jobsitethis means YOU!!!14Additional Measures NeededIf BMPs are failing, the designer must be notified. It is the designers responsibility to find corrective BMPsOwner should also be notified of problemsProblems must be clearly identified, including exact location and observationsSuggestions should be recorded. Often, the person on site can be instrumental to helping the designer find solutions15Key PointsIT 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 controlsAll erosion and sediment controls are inspected weekly and after every of rain, or thawAny 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 SWPPP16Jobsite PollutionWaste and debris that is not properly controlled and disposed of is pollution!

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

18Jobsite PollutionFuel and oil based products that are not contained or properly disposed of are pollution!

19Spill ContainmentThe 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!!!

20Proper storage of hazardous materials will eliminate the opportunity for pollution.Secondary containment is a valuable tool for preventing spills in the first place.

21Display Case and Signage

22SWPPP Site PlanThe SWPPP is a living document that is updated on a daily basis. The SWPPP should be located at the Field Office.

23Silt Fence Examples (BAD!)

24Silt Fence Examples (Good!)

25Silt Fence MaintenanceMust be trenchedMust be installed facing the proper directionMust have properly wrapped connectionsRemove sedimentation when it reaches 1/3 the height of the fenceMust be repaired as needed

26Inlet Protection (Bad)Frames inadequateNot trenchedNot reinforcedNot maintained

27Frames properly builtProperly trenchedReinforced filter fabricAnchoredShould allow for overflow in case of heavy rainfallInlet Protection (Good)

28Seeding and Stabilization (Bad)Lack of stabilization has allowed washout of soilsAreas have remained idle for more than 15 daysMulch or matting could have prevented most of this erosion

29Seeding and Stabilization (Good)Areas have received final grade while other areas are still under constructionPond and channel slopes have received blanket to combat erosionSod installed in concentrated flow areas

30Concrete Wash Out (Bad)Concrete wash out is pollution!Concrete washouts should be provided for delivery trucks.

31Concrete Wash Out (Good)Pit lined with continuous 10 mil linerStormwater run off protected from contamination

32Construction Entrance

BadGood33Citizens can initiate civil suits against:An individual personA construction companyThe U.S. or any other government entityThe EPA itself

34ComplianceAvoid 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.

35ComplianceAnd even more costly fines of up to $25,000 per day from IDEM

36EPA Administrative FinesCurrently $260 Million fines against builders in litigation

EPA Non-Compliance Violations include

No permitNo SWPPPNo inspection recordsNo amendments to SWPPP
