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.

“Trained Individual”Must 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 effectiveness

Must be able to identify BMPs that are failing

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.

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

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.

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

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.

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

groundwater.

Required Job Postings

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

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

Inside the Job Trailer: Original SWPPP Working SWPPP drawing

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 15

days or more) Permanent stabilization

Contact IDEM and Local Authority 48 hours prior to beginning grading activities.

Reporting and Documentation

Reporting 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.

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!!!

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

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

Jobsite Pollution

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

Jobsite Pollution

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

Jobsite Pollution

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

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!!!

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

Display Case and Signage

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.

Silt Fence Examples (BAD!)

Silt Fence Examples (Good!)

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

Inlet Protection (Bad)

Frames inadequate Not trenched Not reinforced Not maintained

Frames properly built Properly trenched Reinforced filter fabric Anchored Should allow for overflow

in case of heavy rainfall

Inlet Protection (Good)

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

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

Concrete Wash Out (Bad)

Concrete wash out is pollution! Concrete washouts should be provided for delivery trucks.

Concrete Wash Out (Good)

Pit lined with continuous 10 mil liner Stormwater run off protected from contamination

Construction Entrance

Bad

Good

Citizens can initiate civil suits against:

An individual person A construction company The U.S. or any other government entity The EPA itself

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.

Compliance

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

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
