Remarks and Recommendations:
Project is out of compliance due to failure to install and maintain erosion control devices and failure to take all
reasonable measures to prevent off-site sedimentation in accordance with section 107-12 of the Standard
Specifications and the Sedimentation Pollution Control Act.
PROJECT RECOMMENDATIONS
Met on site with NCDOT inspectors Jim Holloway and Greg Hamm. Also met with Jim Smith (Project Manager
with Vecellio) at the Christopher Moore Waste Site.
Project is out of compliance due to the failure to install and maintain adequate EC measures and failure to take
all reasonable measures to prevent off-site sediment. The contractor has not been managing runoff, as
directed by the reclamation plan, at the Christopher Moore Waste Site during construction. This has resulted
in a sediment loss and high levels of turbidity into a stream.
-The reclamation plan for this site directed that runoff be diverted with temporary diversions into skimmer
basins. The plan called for a haul road to be constructed between the two skimmer basins. However, bedrock
was encountered, thus making the haul road ungradable and too steep to use. The haul road was rerouted

around the northern skimmer basin which prevented a large area of the waste site from draining to this basin.
A silt fence with two SSCF outlets (SDOs) were used to treat the runoff from this area before leaving the site.
These outlets have been overtopped and severely damaged during recent rain events, which has resulted in a
sediment loss. Recommend repairing the silt fence and SDOs at the toe of slope. Repair any erosion on this
slope and stabilize with seed and matting. Install TSD with adequately spaced TRSC-As and silt basins along
the top of the stabilized slope. Direct TSD into the skimmer basin per plan. This will require that runoff be
piped under the haul road that is being used. The concern for potential sediment loss and erosion at this site
was addressed in the previous inspection report.
-Reestablish/maintain the TSD leading to the skimmer basin on the south end of the Christopher Moore Waste
Site. Ensure this TSD is diverted into the first bay of the skimmer basin. This basin should also be cleaned out
and maintained.
-ESA at Sta. 358+25 LT - Install EC devices per plan. The silt fence has been removed and this area is
currently unprotected.
-ESA at Sta. 379 to 381 LT - Contractor has begun grubbing adjacent to a tributary that leads to Old Field
Creek. No EC devices have been installed.
-ESA at Sta. 373 to 375 LT - Contractor has begun clearing and grubbing adjacent to Ira Jordan Rd. Silt fence
protecting Old Field Creek has not been installed per plan.
-Install skimmer basins at the Joseph Starnes and Stephen Miller Waste Sites per plan. These sites have
been completely cleared and grubbed. Skimmer basins are not yet in place.
-ESA at Sta. 299 RT - The silt fence at the outlet of the skimmer basin has been overtopped with sediment.
Utilize TSD along the slope and slope drain to direct runoff into the first bay. Remove accumulated sediment
and repair silt fence.
-Install TDs to direct runoff from the Donald Blackburn Waste Site per plan. Much of the disturbed slope at this
site is being treated by silt fence and SSCF outlets.
-Sta. 282 +/- LT - Maintain SSCF outlet that is full of sediment.
-Maintain TRSC-As in the ditchline along Y4 LT (Windy Hill Road).
-Sta. 368 LT - Maintain skimmer basin 12.1. Remove sediment from the basin and from the ditchline at the
outlet. Ensure that TRSC-As with PAM are installed and maintained in the ditchline from Sta. 364 to 368 RT.
-Maintain skimmer basin 10.3 - Utilize slope drains to divert runoff into the basin to prevent erosion on the
interior slopes.
-Repair erosion on slopes at Sta. 333 LT. Ensure slope is compacted and stabilized.
-Sta. 267 +/- LT - Install slope drain and outlets per plan.
General Comments
**Make sure that runoff at waste sites is diverted into skimmer basins according to plan. If the plan is unable to
be implemented due to constructability issues, then the plan should be revised by someone with a level III
certification.
**Ensure that any disturbed areas adjacent to jurisdictional areas are protected with silt fence. The silt fence
should be placed along the top of bank in areas protecting stream.
**Ensure that the soil stabilization timeframes as stated on EC-3 of the plans and EC-1 of the proposal are
followed throughout the life of the project.
-Install EC devices according to plan. Any revisions should be approved by the engineer. Keep as-built plans
up to date.
-NPDES records were not reviewed during the project inspection. Ensure all corrective actions are
documented on NPDES forms. Continue to perform inspections once every 7 days and after a 0.5" rainfall
event within 24 hrs.
-Add SDOs at the waste areas to the NPDES forms as directed by the DEO.
-The DEO reviewed this project in the field Thursday and Friday and concurs with this report.
-Project will be reviewed again for compliance in 5 working days.
