This inlet protection device is
ineffective.
How long has it been since this bmp
was inspected and maintained?
You should not be able to see light
under the fence when properly
installed.
Trash dumpsters should receive
regular maintenance and clean out.
Location of dumpster also noted in
SWPPP.
All construction sites that are
pouring concrete must have a
designated concrete washout
receptacle/area.
This site has both trash and track
out which must be reported on the
inspection.
Can you find the problem here?
Potential of flooding this intersection.
This device is installed and working
properly… Problem?
The bmp is installed in an active
parking.
The first silt fence was installed
wrong and therefore the stormwater
flow went around it. The second silt
fence was installed properly but the
rock was placed on top of it.
Where is the channel protection
such as turf reinforcement mat and
vegetation?
Silt fence is not a good
slope break device.
This is what happens when the silt fence at the
top of the slope is not placed exactly on the
contour. It fails after ponding almost two feet of
water behind it.
A proper rock exit is suppose to shake, bounce
and flex the tires to remove the sediment from
the trucks before they leave the site. Milled
asphalt will not create this effect.
This inlet protection needs
maintenance.
The rock in this channel is too big
and therefore provides little or no
protection from the stormwater
flow.
The silt fence is not installed
correctly and sediment is going
under it
The check dams here are not
installed properly with the low point
in the center, so the water moved
around the dam and eroded the
slopes of the channel.
This is the amount of sediment from
erosion of the channel due to an
improperly installed bmp.
What were they thinking? Is there a
detail in the SWPPP for this device?
It appears this bmp might have been damaged when
the rock was placed. This is why it is a good idea to
educate your subcontractors as to the importance of these
devices. Make them responsible and liable for damages.
When straw is not kept in place with
crimping or tackifier, it can float away
and clog ditches, waterways or inlets and
create flooding.
This silt fence
cannot hold back
erosion from this slope.
The slope should have
been finished and fine graded
when the channel work was being
done so both sides could be stabilized
at the same time.
Mulch has floated and is blocking the
channel. This could cause flooding.
Where is the erosion control and soil
stabilization?
The concrete truck driver is not educated about stormwater and doesn’t know
where to washout.
A little too close for comfort. Remember to place
porta-potties, trash dumpsters and storage containers
away from inlets and waterways where they could
enter a waterbody.
 Where is our erosion control? Why don’t
we have grass growing on the slope?
This straw mulch is too deep and might
limit vegetation establishment.
Can you find five deficiencies with this
picture?
Remember When
Doing an Inspection
 Inspect every part of compliance




Permit paperwork
SWPPP
Public entry postings
Best Management Practices
 When writing up the inspection – tell the
story
 What needs repaired or replaced
 When was it repaired or replaced
Inspections
 Keep all the SWPPP
materials together in
order and readable
 Make them
accessible to
contractors and
agencies who do
inspections
 Educate your
contractors and
subcontractors so
they understand how
important it is to stay
in compliance.

When you are done with the
inspection… update the SWPPP and
site maps as necessary
The Site Map
Dates of BMP Installation
and Removal
 First marks on the site map include:
 Installation of construction exit/entrance
 Installation of perimeter control
 Parking, trailer and lay down areas
Maintaining an Updated
SWPPP
 The SWPPP must be amended when the
following occur:
 Changes in design, construction, operation, or
maintenance that may effect the discharge of
pollutants
 During any inspections, it is determined the
discharges are causing or contributing to water
quality exceedances or the SWPPP is ineffective in
eliminating or reducing pollutants in the stormwater
discharge
 Changes in the revised SWPPP shall be
implemented before the next rain event where
practicable.
Records of Stabilization
 Dates when major grading activities
occur
 Dates when construction activities
temporarily or permanently cease on any
portion of the site
 Dates when stabilization measures are
initiated and complete and any reasons
for delays
Major Grading Activities




Removing topsoil
Cut or Fill
Stormwater Basin installation
Utility installation
 Storm sewer
 Sanitary
 Water

Expedited Settlement Offer
The expedited settlement
offer is what the EPA uses to assess fines.
This is a good checklist to make sure the
SWPPP and site are in compliance.
