Approval of this Erosion/Sedimentation Control(ESC) plan does not constitute an approval of permanent road or drainage design(e.g.,size and location of roads, e ,. pipes,restrictors,channels,retention facilities,utilities). `v l I 2. The implementation of these esc plans and the construction,maintenance, Z replacement,and upgrading of these esc facilities is the responsibility of the 0;:>- _ applicant/contractor until all construction is completed and approved and u z p vegetation/landscaping is established. o w Q y r� i '- 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged in u o o 23 Cl 40 ,,y the field prior to construction.During the construction period,no disturbance 1° ^9 ot beyond the flagged clearing limits shall be permitted.The flagging shall be 3 C150 � ;, i maintained by the applicant/contractor for the duration of construction. 4. The ESC facilities shown on this plan shall be constructed in conjunction with all W CJ` clearing and grading activities and in such a manner as to ensure that sediment and sediment laden water do not enter the drainage system,roadways,or violate H applicable water quality standards. L a 5. The ESC facilities shown on this plan are the minimum requirements for anticipated 3 t Temporary Amended site conditions.During the construction period,these esc facilities shall be m 0 Soils Stockpile Area 55c�, upgraded as needed for unexpected storm events and to ensure that sediment = „ N and sediment-laden water do not leave the site.

The ESC facilities on inactive sites shall be inspected and maintained a minimum of o once a month or within the 48 hours following a major storm event. U R m = I 8. At no time shall more than one foot of sediment be allowed to accumulate within 0, v a trapped catch basin.All catch basins and conveyance lines shall be cleaned t - prior to paving.The cleaning operation shall not flush sediment laden water into = U h I the downstream system. a 9. Stabilized construction entrances shall be installed at the beginning of construction ` L U u and maintained for the duration of the project.Additional measures may be ES F— co N required to ensure that all paved areas are kept clean for the duration of the a M o ; L project.
