A. Describe Your Plans and
Procedures for Inspecting BMPs
Your construction general
permit describes the minimum frequency of inspections, which is typically
weekly or bi-weekly and after each rainfall event exceeding one half inch. To
meet the requirement to maintain all BMPs in good working order, EPA recommends
that you develop an inspection schedule that goes beyond these minimums and is
customized for your site and the conditions affecting it.
In developing your
inspection schedule consider the following:
• Consider using spot
inspections. You may want to inspect certain parts of your site more frequently
or even daily. Target places that need extra attention, such as areas around
construction site entrances, check nearby streets for dirt, check inlet protection,
and so on.
• Consider using informal
inspections. Your permit outlines the minimum requirements for formal
inspections that must be documented and included in your SWPPP.
You can also add informal inspections that wouldn’t require documentation,
unless of course, a problem is identified. Always document any problems you
find and those that are identified by staff.
• Consider adding
inspections before or even during rain events. Many permits require inspections
of BMPs after rain events. You should consider adding inspections before or
during predicted rain events. Consult a local weather source and initiate
inspections before predicted storm events as a way to ensure that controls are
operational.
• Train staff and
subcontractors. Use your staff and subcontractors to help identify any potential
problems with your BMPs. Again, document any issues that are confirmed problems.
B. BMP Maintenance
Implementing a good BMP
maintenance program is essential to the success of your Storm
water Pollution Prevention Plan and to your efforts to
protect nearby waterways. You should conduct maintenance of BMPs regularly and
whenever an inspection (formal or informal) identifies a problem or potential
issue. For instance, trash and debris should be cleaned up, dumpsters should be
checked and covered, nearby streets and sidewalks should be swept daily, and so
on. Maintenance on erosion and sediment controls should be performed as soon as
site conditions allow.
Consider the following points
when conducting maintenance:
•
Follow the designers or manufacturer’s recommended maintenance procedures for all
BMPs
•
Maintenance of BMPs will vary according to the specific area and site
conditions
•
Remove sediment from BMPs as appropriate and properly dispose of sediment into
controlled areas to prevent soil from returning to the BMP during subsequent
rain events
•
Remove sediment from paved roadways and from around BMPs protecting storm drain
inlets
•
Ensure that construction support activities, including borrow areas, waste
areas, contractor work areas, and material storage areas and dedicated concrete
and asphalt batch plants are cleaned and maintained
•
Replace damaged BMPs, such as silt fences, that no longer operate effectively You
should keep a record of all maintenance activities, including the date, BMP,
location, and maintenance performed in your Storm water Pollution Prevention
Plan (SWPPP).
C. Recordkeeping
You must keep copies of
the SWPPP, inspection records, copies of all reports required by the permit,
and records of all data used to complete the NOI to be covered by the permit
for a period of at least 3 years from the date that permit coverage expires or
is terminated.
Records should include:
·
A copy of the Storm
water Pollution Prevention Plan with any modifications
·
A copy of the NOI and Notice of Termination
(NOT) and any storm water related correspondence with federal, state, and local
regulatory authorities
·
Inspection forms, including the date,
place, and time of BMP inspections
·
Names of inspector(s)
·
The date, time, exact location, and a characterization
of significant observations, including spills and leaks
·
Records of any non-storm water discharges
·
BMP maintenance and corrective actions taken
at the site (Corrective Action Log)
·
Any documentation and correspondence related
to endangered species and historic preservation requirements
·
Weather conditions (e.g., temperature, precipitation)
·
Date(s) when major land disturbing (e.g.
clearing, grading, and excavating) activities occur in an area
·
Date(s) when construction activities are either
temporarily or permanently ceased in an area
·
Date(s) when an area is either temporarily or
permanently stabilized

During inspections,
consider whether the installed BMPs are working effectively. If you find a BMP that
is failing or overwhelmed by sediment, you should consider whether it needs to
be replaced with a more effective BMP or enhanced by the addition of another,
complimentary BMP. Ensure that you record such changes in your Storm water
Pollution Prevention Plan (SWPPP) and on your site map. To know information
