Circumstances

Provide a complete description of the planned activity or project

TNPI plans on installing river-stone rip rap as a temporary depth of cover remediation for the exposed pipe at milepost 34.8. This installation will be completed before March 31st, 2017.

What is the rationale for the activity or project?

To temporarily provide adequate cover for the pipe before the weather thaws. To have this cover in place before the end of the timing window for carrying out work in fish habitat for the project location (August 1 to March 31). The inclusion of riprap into the channel bed and bank would act to increase channel roughness and therefore decrease flow velocities and erosive stress. This should provide cover until a permanent solution can be decided upon and implemented.

Check all of the following circumstances that apply to this event

Ground disturbance using power-operated equipment within 30 m of a wetland or a water body, or within 30 m of the substrate of a wetland or water body
