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 and a closed Asbestos Waste Disposal Site.
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) Permanent, highly visible Edge-of-Waste markers delineating the waste disposal boundary and are being
maintained as required.
7) Soil has been brought on-site and stockpiled for use in repair projects around the Facility.
8) Heavy equipment traffic along the toe of the eastern sideslope has damaged the cover crop and caused
differential compaction along the eastern landfill boundary. Disposed waste has been exposed in this area at
the southeast corner of the landfill and leachate is seeping in several spots due to the heavy equipment
damage to the 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. Moving forward, please restrict heavy
equipment from this area. If this area is to be used for heavy equipment traffic, a road suitable to support this
use should be constructed.
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) 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.
10) 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. Siltation control fabric fencing
has been placed downslope of the repair. *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.

11) 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 lacking a groundcover suitable to
prevent erosion of the landfill cap system. *Within thirty days of receipt of this Facility Compliance
Inspection Report, please seed and mulch all recently repaired areas to establish a groundcover suitable to
prevent erosion.
12) 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.

13) Overall, this Facility has a well-maintained cover crop of native warm season grasses, however, areas of
sparse cover 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.
14) *It is strongly recommended that while on site for the MSW expansion project, your Engineering Consulting
