BEST MANAGEMENT PRACTICES NOTES
1. This plan should be revised and updated to address changes in site conditions,
new or revised government regulations, and additional on-site
storm water pollution. Additional erosion control measures may be required.
2. All revisions to this plan must be documented on the SWPPP Revision
Documentation Form.
3. Current versions of the SWPPP, the NOI, and the NOC will be kept on site for
the duration of the project. These items will be available for the
use of all operators and site personal involved with erosion and sediment
controls, and be available to EPA visiting the site. A notice will be
posted near the construction entrance during construction, containing the
SWPPP, the NOI and the NOC.
4. Fugitive dust blowing from the site shall be controlled by spraying water and
dust control polymers as needed on dry areas of the site.
5. The contractor will be responsible for supervision and inspection of all erosion
and sedimentation controls and for ensuring the SWPPP is
implemented.
6. Prior to beginning earth-moving activities, including clearing and grubbing, all
clearing limits, easements, setbacks, sensitive areas and their buffers
will be clearly marked to prevent environmental damage both on and off the
site.
7. If sediment is accidentally transported on to the street it will be removed from
the street surface on a daily basis.
8. All off-site construction shall be stabilized at the end of the working day.
9. All waste material will be collected and stored in a securely lidded dumpster.
The dumpster will meet all local and state solid water management
regulations.
10. Portable sanitary units will be provided for use by all workers for the entire
project. Sanitary waste will be collected regularly for the portable units
by an approved sanitary waste management contractor.
11. All exposed soils will be stabilized with vegetation or covered no more than 14
days after the construction activity in that portion of the site has
temporarily or permanently ceased.
12. Existing and new vegetation will be maintained to the maximum extent
practicable to prevent the contamination of storm water with sediment.
13. The contractor shall be responsible for adjusting the erosion control measure;
due to grade changes during the development of the project.
14. Maintain on the site or have readily available sufficient oil and grease absorbing
materials to contain and clean up fuel or chemical spills and leaks.
15. Adequate energy dissipation, erosion control, and soil stabilization measures
will be provided for all point source discharges of storm water,
including run-on discharges and outlets for onsite discharges.
16. Temporary and permanent swells and small detention ponds will be used as
necessary to reduce the velocity of runoff and enhance particle settling.
17. Consistent with the general permit requirements, all potential pollutants other
than sediment will be handled and disposed of in a manner that does
not affect contamination of stormwater.
18. Materials used during construction with the potential to impact storm water, will
be stored, managed, used, and disposed of in a manner that
minimizes the potential for releases to the environment and especially in the
storm water.
19. If a spill of pollutants threatens storm water at the site, the spill response
procedures must be implemented in a timley manner to prevent the
release of pollutants.
20. All temporary and permanent erosion and sediment control BMPs will be
maintained and repaired as needed to assure continued performance
of their intended use.
21. All temporary erosion control and sediment control BMPs will be removed
within 30 days after final site stabilization is achieved or after the
temporary BMPs are no longer needed.
22. Regardless of recommended maintenance schedule, all control measures and
inspections shall be performed within 24 hours following any
storm of 0.5 inches or greater. An inspection report shall be kept at all times
and should be retained for at least three (3) years from the date
the site is stabilized.
23. All contractors providing services on the project which may cause storm water
pollution will be given a copy of the SWPPP and appropriate
training regarding stormwater pollution prevention.
NOTE:
1.AFTER ASPHALT PAVING HAS TAKEN PLACE STORM WATER DEVELOPED WILL BE
DIRECTED TO RETENTION BASINS AND PIPING PER THE APPROVED SITE PLAN
AND PERCOLATE IN DESIGNATED AREAS
2.INLET PROTECTION TO BE PLACED ON ALL STORM DRAIN INLETS AFTER
INSTALLATION THROUGH THE DURATION OF THE PROJECT.
3.WITCH HAT TO BE PLACED ON NEAREST TWO (2) INLET BOXES TO BE
PROJECTED THROUGH THE DURATION OF PROJECT.
