Please see the ADDITIONAL COMMENTS section below for details concerning the violation(s) listed above.

ADDITIONAL COMMENTS:
1) This facility is a closed MSW Landfill, a closed Asbestos Waste Disposal Site and a Landclearing and Inert
Debris (LCID) Landfill.
2) The site is secured by a locked gate at the facility entrance.
3) Proper signage is posted at the entry gate stating the permit number and facility contact information.
4) The facility access road is of all-weather construction and appears well maintained at this time.
5) This facility manages Landfill Gas (LFG) through a collection system which is plumbed to the adjacent active
Onslow County MSW Landfill, permit #67-09 for use at the onsite Onslow Power Producers/Cube District
Energy llc LFG-to-energy plant. The LFG collection system appears well maintained at this time.
6) Facility monitoring wells were reviewed. All reviewed wells were properly secured and labeled.
7) The closed asbestos disposal cell was reviewed. Overall, this area has a well-established cover crop of native
warm season grasses. The cover crop is mowed throughout the year as needed.
8) Wetlands dependent vegetation was observed growing in an area near the western end of the asbestos disposal
cell. The presence of these types of vegetation indicate that this area is restricting the flow of surface waters
which is causing ponding. *Plans need to be underway for the filling and grading of this area to promote the
positive flow of surface waters away from the asbestos disposal cell.
The item(s) listed above were observed by Section staff and require action on behalf of the facility in order to come into or maintain compliance
with the Statutes, Rules, and/or other regulatory requirements applicable to this facility. Be advised that pursuant to N.C.G.S. 130A-22, an
administrative penalty of up to $15,000 per day may be assessed for each violation of the Solid Waste Laws, Regulations, Conditions of a Permit,
or Order under Article 9 of Chapter 130A of the N.C. General Statutes. Further, the facility and/or all responsible parties may also be subject to
enforcement actions including penalties, injunction from operation of a solid waste management facility or a solid waste collection service and any
such further relief as may be necessary to achieve compliance with the North Carolina Solid Waste Management Act and Rules.

9) Permanent, highly visible Edge-of-Waste markers delineating the waste disposal boundary have been installed
in portions of the landfill. *Please ensure the waste disposal footprint is accurately delineated throughout the
entire facility.
10) Overall, this facility has a well-maintained cover crop of native warm season grasses, however, areas of
sparse cover and erosion were observed throughout the Facility. *Within thirty days of receipt of this facility
compliance inspection report, please repair any erosion found in these areas, grade at a slope not greater than
3:1 and then seed and mulch all areas of sparse cover to establish a cover crop suitable to prevent erosion of
the landfill cap system. Application of topsoil or other soil amending material may be necessary in these
areas. Soil sampling and nutrient analysis may be beneficial to determine the necessary steps needed to
establish and support a healthy cover crop.
11) Erosion and differential settlement repairs have been partially completed. However, significant erosion of the
repaired area has occurred on the southern sideslope. *Within thirty days of receipt of this facility compliance
inspection report, please repair the eroded repair areas, grade at a slope not greater than 3:1 and then seed and
mulch to establish a cover crop suitable to prevent erosion of the landfill cap system. Moving forward, all
repaired areas should be seeded and mulched promptly upon completion of any repair project.

12) Off-site erosion was observed on the southern sideslope downslope of the eroded repair area. Sedimentation
was observed outside of the waste disposal area and in the surface water ditch. The siltation control fencing
placed downslope of the repair has been over-washed by surface waters and sediment. *Within thirty days of
receipt of this facility compliance inspection report, please remove all sedimentation found outside the
permitted disposal area and return it to the repair project area.

13) The areas of differential settlement and erosion that were previously observed on the northern and southern
outside slopes and documented in previous facility compliance inspection reports have been filled and graded
but were noted during this facility compliance inspection as still lacking a groundcover suitable to prevent
erosion of the landfill cap system. Erosion of the repairs has occurred and sediment has been conveyed to the
toe of these slopes. *Within thirty days of receipt of this facility compliance inspection report, please repair

these eroded areas. After completing these repairs, seed and mulch all repaired areas to establish a
groundcover suitable to prevent erosion.
14) Areas of seeping leachate were observed in some of the eroded areas on the southern and eastern sideslopes.
No leachate from these seeps was observed leaving the permitted disposal footprint of the landfill. *Within
thirty days of receipt of this facility compliance inspection report, please repair the landfill cap system in all
seeping areas. The repaired areas should be graded at a slope not greater than 3:1, seeded, and mulched to
establish a groundcover suitable to prevent erosion of your landfill cap system. Please monitor all repaired
areas for continued seeping. Any areas where leachate continues to seep should be addressed promptly to
prevent the release of leachate outside the permitted disposal boundary. Moving forward, please ensure these
areas and all landfill sideslopes are maintained at a slope not greater than 3:1 to promote the positive flow of
surface waters from the landfill disposal boundary. Areas of differential settlement should be repaired
promptly to prevent the ponding of surface waters.
15) Heavy equipment traffic along the toe of the eastern sideslope has caused differential compaction along the
eastern landfill boundary, damaged the cover crop, and damaged the landfill cap system. *Within thirty days
of receipt of this facility compliance inspection report, please repair the damage that has occurred to landfill
cap system in this area and grade the area to promote positive drainage of surface waters away from the
landfill. Moving forward, please restrict heavy equipment from this area until a road suitable to support this
use has been constructed.
