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, pipet, restrictors, channels, retention facilities, utilities, etc). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the permit tee/contractor until all construction is approved 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged in the field prior to construction. During the construction period, no disturbance beyond the flogged clearing limits shall be permitted. The flagging shall be maintained by the permittee/contractor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed in conjunction with all clearing and grading a,_livities, and in such a manner as to insure sed,m erl laden water does not enter the drainage system or violate if ;_ it le water standards (KCC 9.04 020 AA, KCRS 7.09 D). 5 The ESC facilities shown on this plan are the minimum requirements for anticipated site condition. During the construction period, these ESC facilities shall be upgraded (eg additional sumps, relocation of ditches and silt fences, etc) as needed for unexpected storm events (KCC 9 04 09C B2) 6. The ESC facilities shall be inspected daily by the permiltee/contractor and maintained as necessary to ensure their continued functioning (KCC 9 04 090 62) 7 Any area stripped of vegetation, 1-2 ;ding roadway embankments, where no further work Is ontiUFnted for a period of 15 days, shall be immediately stabilized with the approved ESC methods (e 9 seeding, mulching, netting, erosion blonke's, etc ) ;KCRS 7. 090 D), 8 Any area needing ESC measure, not requiring immediate attention, shall be addressed within fifteen (15) days 9. The ESC facilities on inocti.e sites shall be inspected and maintained a mirdmum of once a month or within the 48 hours following a storm event 10 At no time shall more than one foot of Sediment be allowed to accumulate be w•thin a catch basin All catch basins and conveyance lines shall be cleared prior to paving. The cleaning operation Shag not flush sediment laden water into the downstream system 11 Stabilized construction entrances and wash pods shall be Installed at the beginning of canstruction a1,d momtoined for the duration of the project. AddO.Cral measures may be required to insure that all paved areas are kept clear for the duration of the project. (RCW 46 61 655) 12 During the time period of November 1 through Morcn 31, all project disturbed areas greater thor 5,000 square feet lhot r e be left unworked for more than 12 hours sholl be covered by are c` the following cover measures. mulch, sodding or plastic covering 13 Any permanent retencorl/detention facility used as a temporary settling basin shall be modified with the necessary e,osion control measures and shall provide adegr.ote storage capacity If the permanent facility is to fu,,Ltior ulthr otely as an lnfiltrohon or dispersion system, the facility shall not be Used as a temporary settling basin No urldergr our deter lion ^inks or vaults shall be used as a lemparary settling basin.
