Contractor’s construction TESC Plan and implementation schedules <br />must be prepared by a competent individual. Furnish a signed copy of <br />the TESC Plan with individual’s name, title, state certifications, and <br />employing firm if different than Contractor’s firm. <br />5. Do not begin any Site activities that have potential to cause erosion or <br />sediment movement until the TESC Plan and implementation schedules <br />are approved. <br />6. Keep a copy of the approved TESC Plan with updated changes onsite <br />during all construction activities. During inactive periods longer than <br />7 calendar days, keep the TESC Plan onsite. <br />7. Continually update the TESC Plan and schedules as needed for <br />unexpected storm or other events to ensure that sediment-laden water <br />does not leave the construction site. Add approved changes to the TESC <br />Plan no later than 24 hours after implementation. <br />E. Preventing erosion, and controlling runoff, sedimentation, and non-stormwater <br />pollution, requires Contractor to perform temporary Work items including, but <br />not limited to: <br />1. Providing ditches, berms, culverts, and other measures to control <br />surface water. <br />2. Building dams, settling basins, energy dissipaters, and other measures, <br />to control downstream flows.
