(e) Re-watering. After completing work, re-water the construction site according to Subsection 107.10(d)(1)(d).

(f) Site Restoration. After completing in-water work, repair damaged stream banks and restore the area according to Subsection 107.10(d)(1)(c).

157.11 Waterway and Slope Protection and Stabilization. Delete paragraph (c) and substitute the following:

(c) Check dams. Construct riprap, filter rock, gravel bags, sandbags, fiber rolls and socks, or earth berms for temporary check dams to reduce the velocity of runoff in ditches and swales.

157.12 Temporary Soil Stabilization. Add the following after the first sentence:

Perform this work on all cut and fill slopes that will be unattended for 14 days or more.

157.14 Inspection and Reporting. Delete the text of this Subsection and substitute the following:

Specify in the project SWPPP (tab 9) which inspection schedule will be used and use the same schedule throughout the duration of construction.

Furnish completed inspection reports to the CO within 24-hours after performing an inspection.

When construction is suspended for seasonally-frozen conditions, inspections may be suspended (temporarily) if disturbed areas are stabilized. When inspection frequencies are reduced, document reasons in the SWPPP (tab 9). Resume the normal inspection schedule when the construction site thaws or construction activities resume.

157.15 Maintenance and Cleanup. Delete the text of this Subsection and substitute the following:

Maintain the functionality of erosion and sediment control measures, and clean measures that are half-full of sediment, until final acceptance or until disturbed sites are stabilized according to the CO. Remove and dispose accumulated sediment according to Subsection 204.14.

Implement maintenance of erosion and sediment control devices or other corrective action within the following time requirements:

(a) In the event of discharge of sediment or other pollutants, immediately take steps to prevent further discharge until a permanent solution is installed and made operational;

(b) Begin corrective maintenance of sediment and erosion control devices within 24 hours of discovery and complete as soon as possible.
