Permit Consultation Comments:
A PCN is being issued to document the loss of sediment and other material into permitted areas. High intensity rainfall late Friday
resulted in loss of material. DWO has been notified of the loss of silt and other material. Please notify this office when sites are
restored,
A PCN is also needed to discuss NPDES record keeping. In order to relieve PCN and ICA status NPDES records need to be
accurate and up to date.
Remarks and Recommendations:
Project was reviewed by Roadside Environmental Field Operations Technician, Tommy Chapin.
ICA status will continue due to offsite sediment caused by heavy rains after time of last review and not completing items on e.c. list.
Talked with contractor and with proj. inspector, Chad Johnson, while on site.
After time of last review on 5/27/11 project encountered heavy downpour of 2 inches.
This has caused additional problems and has hindered contractor to complete e.c. list.
There is offsite sediment/material in ditch & creek at sta 18+25rt of L, in Big Buffalo Cr. at sta 52+00L and approx. sta 37+00 to sta
38+001t of Y. Mason Herndon from DWQ was contacted and indicated that material needs to be removed by hand.
All items on e.c. list need to be completed.
Skimmer basins were being addressed at time of review. There is still considerable work needed to complete skimmer basin
construction throughout project.
Contractor has started to address seeding needs. Strongly encourage contractor to continue with seeding efforts to cover bare
areas of project and meet 21 day seeding requirement.
Note the following corrective needs:
1) End of Y-med- at end of disturbed area- install type a check as an offsite measure,
2) Many of the wrapped type a checks along Cumnock Rd. and from sta 62+50 to sta 68+00rt of L are poorly constructed. Devices
are too high, esp. weir sections. Need to lower weirs so flow will pass over rock not run around.
3) sta 22+50rt of ramp c- skimmer basin needs maint. and repair, asap.
4) sta 19+50 to sta 23+00rt of ramp c- temp. s/m bare areas.
5) sta 14+00rt of ramp c- skimmer inlet needs to be reset to function property. Rock platform for skimmer looks high.
6) sta 23+00 It of ramp b- need to stabilize disturbed area of channel with liner.
7) sta 15+00 to sta 24+001t of ramp b- Temp. s/m bare areas along stream including slopes along haul rd,
8) sta 24+00 to sta 27+001t of ramp b- Still need to install measures, as per plans. One of the tiered skimmers has been removed
due to fill work. Need to replace with trsd-b with equal storage. Temp. s/m ditch/slopes.
9) Continue to address stockpiles as project progresses,
6/711110:33 Page 1 of 2

10) Access road off Cotten Rd.- Complete e.c. installation work and slm perimeters.
12) sta 68 +00rt of L- install type a check across outlet, as per plans.
13) sta 82 +20rt- install wrapped type -a check as per plans.
14) sta 95 +00 to sta 105+00- active grading- install measures, as per plans. Begin stage seeding of slopes/ditches in a timely
manner.
15) sta 53 +00 to sta 82 +00- active CIG section- Install measures as per CIG plans, esp. on rt. side. Temp. slur perimeter berms
and devices.
16) Need to continue with work on skimmer basins. Need to ensure that the following items have been addressed- adequate coir
fiber matting at outlet end of skimmer, need to ensure fabric is secured around slope drain pipes and skimmer pipes through dam
to prevent possible failure, need to ensure fabric covers entire dam and wraps around sides of dam, ensure adequate staples are
being used to secure fabric, ensure side slopes are no steeper than 2:1, ensure berms and slopes are seed /matted, ensure slope
drain pipe has been cut off even with earthen berm and ensure skimmers are repaired and in good working order.
17) Need to adequately tack with approved material recent slm areas. Approved material is hydromulch and asphalt tacking.
18) Continue to seed /mulch disturbed areas to meet 21 day seeding requirements.
Permitted areas -
1) sta 52 +OOL- Need to hand remove loss silt in Big Buffalo Creek at two locations as directed by DWQ.
- Due to field conditions recommend adding two basins, at sta 51 +00 L, N. of Big Buffalo Cr. At this time Roadside
- E=nvironmental Unit has been contacted to design these basins.
- S. side of creek- Need to place filter stone up against hardware cloth.
2) sta 18 +25rt of L- Need to hand remove loss silt in Patterson Creek as directed by DWQ.
3) sta 38 +001t of Y- Need to hand remove 57 stone in Big Buffalo Cr, as directed by DWQ.
4) sta 88 +001t- need diversions across access road, both sides of creek.
5) sta 105 +00rt- Still need to repair sscf next to skimmer basin- poor installation
6) sta 105 +001t - stream crossing stilt needs attention. Need additional & fresh stone.
- Install diversions across access road both sides of creek.
7) sta 119 +50 to sta 120 +001t of L- extend silt fence to skimmer basin.
8) Ensure skimmers are properly installed and maintained!
General Comments: On TRSD's and silt basins w/TRSC's, ensure rock outlet measure goes across entire outlet area and proper
weir section is installed, as indicated on plans. TSD's need to be constructed with 2:1 side slopes and a minimam of 1 ft. depth.
Also, ensure TRSC's are constructed, as per spec. Additional hand work may be needed on some of these devices In order for
them to be shaped properly.
A Permit Consultation is needed to discuss NPDES record keeping. It is evident that additonal training is needed for Level 11
personel. Need to ensure NPDES reports are being completed once a week and after each 112 inch rain event within 24 hours.
Need to list all SDO's on each report and daily rainfall log needs to be completed. Ensure that E.C. plans are updated and marked
at the end of each day. Also maintain records on site for review by Department & Regulatory Personnel.
Project will be reviewed again for compliance in 5 working days
