Track out occuring from the access road b/t the City's Lift Station and the Idaho River Sports Co. I suspect its from local people using it to get to the white water park/greenbelt. Talked with Alta Construction, they stated they been done working since october. Knife River has been finished since May. Contacted and left a VM to ACHD Jason Korn about the trackout.

Lift station and related infrastructure is installed. BLD permit is open Other phases of 31st/Whitewater Blvd project are ongoing. No stabilization yet. No violations at this time.

WIP and site is not yet ready for stabilization. NO ESC violations at time of inspection. Dewatering and sewer infrastructure has been installed. Approved

Need to achieve final stabiliztion

Need to break down basin and stabilize all portions of the disturbed soil.

after establishing the discharge lines and discharge points into both the basin and pond, Knife River purged the well by pumping into the basin. At this time we took NTU measurements on the pond (background). the reading was 7.58 rounding up to 8 NTU's.
Giving them an allowable discharge of 58 NTU's.
At 3:25pm mountain standard time, the hard line discharge hose had a reading of 37 NTU's. The flexible line had a reading of 44 NTU's.
Knife River will now divert the hard line discharge to go directly into the pond. While they are estblishing there contections they will keep the flexible discharge line puming into the basin so a "purge" will not have to occur again. They will be pumping throught out the night. Once land disturbing activities begin in the morning all of the discharging will go directly into the basin with no discharges out into the pond.

No actiity until 3/8/2013

Dewatering of trench is complete. All water appears to have been retained on site in the retention basin and no discharges to the vegetated upland area occurred.

on 2/25/2013, Knife River reached ground water at 6.5ft. They stopped all activities with the utility pipe installation and began to impliment thier dewatering plan. Once completed with the detention basin and a well point, they will be calling for an inspection to review the dewatering activities.

ESC/ SWPPP approved. Explained to the RP to review the dewatering portion of the plan. It states, well point and drainage swale will be constructed prior to any dewatering from occuring. The plan states ground water is at a potental of 11ft below grade. Explained to RP if ground water is reached ant it is needed to dewater, The project must stop all activities and impliment the dewateering plan. Will follow up on 2/26/2013
