Permit Consultation Comments:
A "PCN" is being issued to document off -site sedimentation into jurisdictional areas. Mason Herndon with DWQ has been
contacted and has advised contractor to remove sediment from streams by hand.
Remarks and Recommendations:
Rode through project with Barry Brewer, wIDOT and Jerry wlBarnhill. Project was reviewed on May 17th & 19th.
Project is out of compliance due to failure to maintain erosion control devices, failure to take all reasonable measures to prevent
off -site sediment, and failure to follow approved plan. Please note the following corrective action at the three off -site locations.
1) US 220(Y12) - approx. sta.65 +00 Rt. on Y12 - off -site sediment has occurred in this location. Contractor will need to remove
sediment from outlet ditchlstream that exits into jurisdictional stream. Also, need to remove sediment in two locations in major
stream. I talked to Mason Herndon wIDWQ on May 20th and he gave us permission to remove sediment in this area by hand. Need
to install special sediment control fence in low area at silt fence failure, asap and seed/mat slope. Recommend installing additional
slope drain and basin, as shown on plans at 01, as discussed to divide up drainage area on subgrade. Also, install TRSC at end of
rock -lined ditch.
2) US 220(Y12) - (This site was reviewed on May 17th and again on May 19th.) Approx. sta.79 +50 Rt. on Y12 - contractor has
started hauling into this section. During storm event over the weekend, sediment was lost off -site into stream due to silt fence
failure. Mason Herndon w /DWQ was notified on Monday and indicated sediment deposits could be removed form stream. Sediment
deposits were removed from stream on May 18th. There continues to be one area that needs sediment removal at stream and also,
need to remove sediment control stone and small amount of sediment at right -of -way fence. At time of review, today, contractor has
installed additional slope drains and basins, as discussed on May 17th. Need to seedlmulch slope, asap.
Approx. sta.79 +50 Lt. on Y12 - contractor has performed maintenance to silt fence and basins. Seed /mulch disturbed areas, esp.
slope, asap,
3)"Sta.450 +00 Rt. at culvert site - need to remove sediment in stream at old temp. stream diversion, re- construct stream bank, and
seed/mat. Need to remove silt fence at outlet end of top drainage pipe and install scour hole, as shown on plans. Recommend
diverting runoff into woods until streambank is stabilized. Also, need to remove blockage inside culvert.
4) Please see additional corrective actions that need to be addressed throughout project.
Approx. sta.135 +00(Spencer Rd.) to Banner Whitehead Rd.(Y3) - contractor continues to actively grade in this section. Approx.
sts.133 +00 to sta.141 +00 Rt.- contractor has seeded /mulched ditchline. Repair washes and seed/mat. As work continues, stage
seed /mulch slopes. Ensure runoff is diverted into skimmer basin(ID.- 7.3CG) and drainage areas are divided up, as not to overload
one basin. "Sta.147 +50 Rt.- contractor has installed rock plating on slope at inlet end of pipe. Need to remove rock from bottom of
stream channel and stabilize slope Rt. of finished ditch at wingwall wlseed /mat. Grade & stage seedlmuich fill slopes in this area

General comments: Contractor continues to actively grade, esp. on the north end of project and on south and at US 220. As
grading work continues, ensure disturbed areas are reviewed at the end of each workday and install temp, diversions or additional
e. c. measures, as needed to ensure runoff is managed and diverted to skimmer basinsrrRSD's. Drainage areas should be divided
up, as not to allow runoff to overload one single measure in sensitive areas and result in off -site issues. Recommend at least a
wattle or wrapped TRSC wIPAM near inlet end of all basins to help reduce turbidity throughout project,

Contractor needs to ensure erosion control measures are installed and maintained, as per erosion control plan and NPDES
requirements.
Seeding contractor is performing repair seeding work on project at this time. Continue to repair washes and ditch erosion
throughout project and seed /mat these areas, as well as weakly vegetated slopes. This work needs to be completed in the next few
weeks to get good germination of seed before hot weather conditions. Continue to stage seed/mulch slopes as work continues and
temp. seed/mulch, as needed to meet 21 day seeding requirement. Also, ensure safety fence is maintained and re- installed, as
needed throughout project.
NPDES documentation was not reviewed due to lack of time. Continue to complete NPDES documentation weekly and within 24
hrs. after an .5 or greater rainfall event. Also, continue to update clearing/grubbing and final e. c. plans. Documentation will be
reviewed before lifting "ICK.

The " ICA" status on this project has been lifted at this time. A follow -up review was conducted on May 27, 2011 with Jeff Loflin,
Resident Engineer, John Partin, Asst. Resident Engineer, Vickie Davis, Roadway Construction Engineer, Tim Latham w /Land
Quality, DOT inspectors, and contractor personnel that indicated corrective actions have been taken to bring the project back into
compliance. Majority of issues on the project have been completed at this time.
Please note the following comments and recommendations:
1) US 220 at approx. *sta.65 +00 Rt. on Y12 - sediment has been removed from stream, as per Mason Herndon w /DWQ. Need to
continue to monitor ditch /stream and remove additional deposits as they migrate down after each rain event. Erosion control
measures have been installed, as per plans.
2) US 220 at approx. *sta.79 +50 Rt on Y12 - off -site sediment has been removed, except for one area that needed additional
attention. Erosion control measures have been installed and maintained and slope seeded /matted.
3) *Sta.450 +00 Rt, at culvert site - sediment has been removed from stream and bank seededlmatted. Recommend diverting runoff
from down pipe into woods to avoid future erosion on stream bank. Also, need to final grade areas up and around culvert headwall
area, re- install silt fence /special sediment control fence, and seed/mat.
4) *Sta.147 +50 Rt.- need to re -grade and stabilize small slope area Rt. of finished ditch at wingwall. Also, need to re-seed/mat ditch
bank adjacent to right of way line. *Sta.269+00 Lt.- need to seed disturbed areas with native grass seed mix. Also, need to re- install
orange fencing in permitted area. From Branson Davis Rd. to existing US 311(Y7) - continue to repair seed /mulch weakly
vegetated areas throughout this section. Dry detention basin #13 - repair washes /disturbed areas on slopes and seed /mat. US 311
- repair ditch erosion in ditchline on US 311 at RP213.
General comments: As hauling and grading continues on project, please ensure at the end of each day, that lifts of material in fill
sections are coordinated to ensure runoff on subgrade is directed into skimmer basins. The contractor may have to install temp.
diversionslberms or additional slope drains depending on subgrade, as needed to divert runoff to skimmer basins in a controlled
manner. Ensure erosion control measures are installed, as shown on plans, esp. silt basins at DI's and e.c. measures are
maintained, as per NPDES regulations. Continue to stage seed/mulch slopes and median sections, as soon as possible and temp.
seed/mulch, as needed to meet 21 day seeding requirement.
