PRELIMINARY NOT FOR CONSTRUCTION
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 N01, 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 N01 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 sedimental....
controls and for ensuring the SWPPP Is Implemented,
B. Prior to beginning earth -moving activities, including clearing and grubbing, all clearing limits,
easements, setbacks, sensitive areas and their buffers will be dearly 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 stale 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 dean up fuel or chemical splits 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.
18. Temporary and permanent swells and small detention ponds will be used as necessary to reduce the
velocity of runoff and enhance particle setting.
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 SMPs 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 limes 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 slormwaler pollution prevention.
