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 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
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 Goal
Protect 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

installation of the following:
Construction entrance (s)
Silt fence or other barrier BMP
…BEFORE any major grading
Check dams
Diversion drains

days or more)
Permanent stabilization
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 binderSite 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!!!
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.
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
Inlet Protection (Good)





Frames properly built
Properly trenched
Reinforced filter fabric
Anchored
Should allow for overflow
in case of heavy rainfall
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
Good
Bad
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
