Still working on the pond areas.

Entrance into the work area where pump and front end loader is located next to the basin needs filter fabric and wash rock to reduce trackout. Complete entrance within two working days.

Area is activily beeing worked at the most South East end of project area where screening is occuring.

Appling a tachifier mulch mixture. Will be mostly completed with all areas be the end of today.

Verdal correction to Knife River (permit holder):
Temporarily or perminately stabilize all disturbed soil that has been or will be inactive within 14 days. Will re-inspect on 12/8/09am.

Discussed final and temporary stabilization methods with Randy of Knife River. Informed Randy that to file the NOT with EPA that final stabilization must be achieved and for temporary stabilization area will need to continue with inspections until final by EPA definitions (CGP) has been completed, e.x. 70% top growth, wash rock, etc. Also outlined the correct methods for stablizing swales and RECP, e.x. soil amendments, seed, blanket then moisture to ensure growth. Will follow up.

9:30 with ACHD: Reminded all parties that any changes with SWPPP is required to have the plan modified and inserted into the plan. Met with representative from the ParkCenter Bridge and Road re-alignment projects.

Verbal to Consultant that contacted RP:
Sediment barrier is required alond the access pont on the South sideof the Penn Canal where front loader has driven through. Will re-inspect on 7/13/09am for compliance.

De-watering is being performed into an on-site basin. No discharge off site is occurring. Last basin is appr. 80% completed.

Found a high level of turbid water collecting within the Walls Creek. Required that the contractor to take sample of the there discharge. There back ground is 13.1 NTU's. So they are allowed to reach 63.1 NTU's. Will discuss with them on 7/6/09 for there readings. If the the Turbidity is over 63.1 NTU's further enforcement will occur. Will re-inspect on 7/6/09 AM.

Knife River provided to ESC a revised dewater plan. Inspectors 420 and 460 walked site. Water is being transferred under Warm Springs Road to the south side, (same owner). Area is highly vegetated. Wallings Ditch flow is un-noticeable & clarity appears to be unclear. Dewatering has not reached Walling at the time of our inspection. Recommended to Knife River to collect turbidity samples from Wallings to determine NTU numbers. Ok to have discharge into Wallings if turbidy is in compliance with State Of Idaho Water Quality Standards. Also informed Knife R. to continue to monitor dewatering over the weekend and if discharge into Wallings occur and exceeds standards to discontinue discharging. Boise City will follow up next week.

Site had been discharging turbid water from construction project. Discussed options with engineer, (Dave Powell). Stop work was placed on dewatering activities until additional options can be implemented. Summary of options suggested by engineer are: 1) install silt fence (northeast) to direct water to west part of project away from off site animal pens, 2) re-work west basin to receive re-directed water, 3) water will then get pumped into west basin from east basin, 4) water will then be pumped into vegetation to endeavor to remove the majority of sediment. I suggested that multiple points of discharge be used into vegetative area instead of one main area of discharge. This is the second time that this mulitiple points of discharge has been recommended. Also, informed engineer and contractor that it is their responsibility to comply with NPDES/ESC requirements of only discharging non-turbid water from the site. This moring turbid discharges were observed and documented leaving the site into Penn canel and into established wetlands. Once additional bmp's are in place the directives were to contact Steve W. at which time re-commencing of dewatering may start and the stop work will be lifted. Also, if this option does not work to reduce turbidity then the contract will need to stop and re-think the scope of work and re-submit additional plan to Boise City ESC division.

STOP WORK ORDER.
(Written notice to Randy with Knife River).
1. Ilicit discharge of turbid water in multiple points throughout the project:
~ discharge offsite the project area into the protected wetland area due to dewatering into the grassy area to the east side of the most south basin.
~~ discharge of water that has channeled off site into a pasture that is full of aminal feces into the Penn Canal. Water is turbid and polluted with feces into the Penn Canal. Please refer to the STOP WORK ORDER HOLD for further stipulations regarding the stop work order hold. Will re-inspect once stipulations are met by the contractor.

No activiities observed. Sign posted, water from offsite into Penn Canal is discharging large volume which appears to be faily turbid free. Contractor was informed that filter capacity of dewatering from basin are limited due to saturation of ground due to above average rainfall. Continue to monitor water and if turbidiy is observed then other options or ceasing work until water can infiltrate and top growth can dry is recommended. Discharge of turbid water from the site is not acceptable or allowed.

All looks good. But area of concern is now dealing with ground water and the process of dewatering. Will monitor this week on 6/11/09.

Performed on site conference yesterday, not ready for site preparation inspection. Site preparation inspection has been scheduled for 6/9/09.

9:00am Meet with Ground FX and Knife River over the implimenting the ESC/SWPPP plan. Met with Knife River, Dave Powell, (RiverRidge), Ground FX for erosion control discussion regarding upcoming project.
