Storm Water Pollution Prevention Plan (SWPPP) 1.2 SUMMARY A. The intent of this specification is to provide guidelines for the Contractor to adhere to all state, federal, and local environmental regulations. It is also the intent to provide preventive measures to keep sediment from entering any storm water system, including open channels. It is the Contractor's responsibility to adhere to all state, federal, and local requirements. While the Owner may require the Contractor to install erosion control devices during construction, this will in no way relieve the Contractor of his responsibility. 1.3 GENERAL A. Comply with applicable requirements of all governing authorities having jurisdiction. These Contract Documents are not represented as being comprehensive, but rather to convey the intent to provide complete slope protection and erosion control for both the project site and the adjacent property. B. Erosion control measures shall be established at the beginning of construction and maintained during the entire length of construction. On-site areas which are subject to severe erosion and off-site areas which are especially vulnerable to damage from erosion and/or sedimentation are to be identified and receive additional erosion control measures as directed by the Owner. C. All land-disturbing activities shall be planned and conducted to minimize the size of the area to be exposed at any one time and to minimize the time of exposure. D. Surface water runoff originating upgrade of exposed area shall be controlled to reduce erosion and sediment loss during the period of exposure. E. When the increase in the peak rates and velocity of storm water runoff resulting from a land-disturbing activity is sufficient to cause accelerated erosion of the receiving ditch or stream, the Contractor shall install measures to control both the velocity and rate of release so as to minimize accelerated erosion and increased sedimentation of the stream as directed by the Owner. F. All land-disturbing activities shall be planned and conducted so as to minimize off-site sedimentation damage. G. The Contractor shall be responsible for periodically cleaning out and disposing of all sediment once the storage capacity of the drainage feature or structure receiving the sediment is reduced by one- third. The Contractor shall also be responsible for cleaning out and disposing of all sediment and removal and disposal of all erosion control products at the time of completion of the Work. Biodegradable erosion control products may be left in place or mulched at the site if approved by the Owner. 02270 - 2 Erosion and Sediment Control Nelson + Morgan, Architects Demolition of 301 E.

All sediment shall be prevented from entering any storm drain, ditch or water course through use of sand bags, gravel, boards or other approved methods. E. The construction entrance shall be maintained in a condition which will prevent tracking or flowing of sediment onto public rights-of-way. This may require periodic top dressing with additional stone as conditions demand and repair and/or clean-out of any measures used to trap sediment.
