1.0 POST-CLOSURE CARE PERIOD
This Post-Closure Care Plan will serve as the document to describe post-closure maintenance
activities to prevent the landfill from becoming a hazard to human health or the environment.
Any revisions to this Post-Closure Care Plan will be made by the facility and the amended plan
placed in the “Operating Record” of the facility and a copy provided to the North Carolina
Department of Environmental (NCDEQ), Division of Waste Management, Solid Waste Section
(SWS).

The East Burke Landfill, Permit No. 12-02, is located at 8827 Rhodhiss Road, SR 1611, in
Connelly Springs, Burke County, North Carolina. The area surrounding the landfill is primarily
residential/agricultural and contains open fields and woodlands. The landfill operated as Burke
County’s Landfill between 1972 and 1988 and has been closed to the reception of waste since
1988, thus beginning the post-closure care period. The landfill is regulated under Rules .0500
and .0600 of the North Carolina Solid Waste Management Regulations (NCSWMR) for
municipal solid waste landfills (MSWLF) closed prior to October 9, 1993.

Following closure of a solid waste landfill unit, the owner or operator shall conduct post-closure
care. Typically, post-closure care is conducted for 30 years; however, the length to the care
period may be decreased or increased based on the site conditions and demonstration to protect
human health and the environment.

2.0 POST-CLOSURE CONTACT
Burke County will handle questions and/or problems that may arise during the post-closure care
period.

CONTACT PERSON: Miles Champion, General Services Director
ADDRESS: Burke County General Services

3.0 INSPECTION, MAINTENANCE, AND MONITORING PLAN
A semiannual inspection program will be conducted throughout the post-closure care period for
the site. If problems arise, the inspections may be made more frequently depending upon the
severity of the problem. Potential impact to the public and environment will be a factor in
determining the inspection interval. A post-closure inspection form is provided in Attachment A
to this Plan.

Throughout the post-closure care period, the following areas will be inspected on a semiannual
basis:

East Burke Landfill, Burke County, Permit 12-02 Joyce Engineering
Post-Closure Care Plan July 2017
Page 2
 Access and security control;
 Posted signs;
 Final cover system for
o Possible leachate outbreaks,
o Erosion damage,
o Settling/ponding,
o Vegetative cover;
 Integrity of surface water drainage ways and impoundments;
 Groundwater monitoring system; and
 Landfill gas monitoring system.

The form provided in Attachment A should be completed for each inspection. Copies of the
inspections will be kept by Burke County General Services Office and available to NCDEQ for
their review.

If an inspection reveals needed maintenance, maintenance activities will be initiated as soon as
possible, and in no case later than 90 days after discovery of the need. Necessary resources for
the performance of maintenance will be available from Burke County.

3.1 Security Control Devices
Throughout the post-closure care period, fencing, lockable gates, and other natural and/or
artificial barriers will be maintained to control access to and from the landfill property. All gates
will be clearly marked with signs stating the name of the facility, that solid waste was disposed
on the site, and that the site is no longer used for disposal purposes. Missing or damaged
security locks will be replaced when discovered during inspections. Damage to the gate or
perimeter fencing which interferes with their intended function will be repaired promptly. Edge-
of-waste markers and property boundary markers will be maintained in good condition.

3.2 Leachate Monitoring
Monitoring of the landfill for possible leachate issues will continue throughout the post-closure
care period of the site. Semiannual inspections will be made to look for any possible leachate
outbreaks. Personnel responsible for performing site inspections and maintaining the site will
be competent individuals trained in the skills necessary to perform their job. Personnel will
continue to receive training as new programs become available. If major problems arise,
competent engineering and construction firms will be engaged to assess the situation and
recommend ways to alleviate the problems.

3.3 Erosion and Settlement
Erosion damage such as gullies that develop on the vegetative soil layer of the final cover system
will be repaired when the gullies are greater than six inches deep. Eroded areas will be filled
with soil capable of sustaining vegetative growth. The surface of the soil will then be reseeded,

East Burke Landfill, Burke County, Permit 12-02 Joyce Engineering
Post-Closure Care Plan July 2017

fertilized, and mulched to reestablish vegetation.

If differential settlement produces low areas where rainwater can pond, the areas will be filled,
compacted, and re-graded to allow efficient runoff. The surface of the soil will then be reseeded,
fertilized, and mulched to reestablish vegetation.

3.4 Vegetative Cover
Post-closure maintenance will include mowing of the grass cover. This will be done to improve
the stand of grass being developed on the landfill cap and to allow inspection of the cap. During
the normal post-closure period, the site will be mowed a minimum of two times per year to
maintain the grass cover. In addition to mowing, post-closure activities may include seeding as
needed. In the fall of the year, the vegetative cover will be evaluated. A plan for reseeding will
be developed based on the needs of the site during that year. The seeding will be applied during
the fall planting season.

After closure of the landfill, pine trees were planted on top of the landfill cap, and the trees are
now mature. By establishing a permanent root network, the vegetative species will help retain
the slopes from erosion. The established species of trees will help stabilize the landfill slopes
and shall be maintained. Dead trees and shrubs, fallen branches, and excessive undergrowth
shall be removed. A park-like appearance is desirable. The following specifications shall be
maintained:

 All trees with diameters of four inches (4”) or less measured at breast height shall be
removed. Root balls may be left in the ground, but the stumps should be left no higher
than 6 inches (6”) above grade.

 Dead trees shall be removed. For dead trees with diameters larger than four inches (4”)
measured at breast height, the condition of the root ball should be assessed to determine if
it needs to be removed. If the root ball is sufficiently rotted or uprooted such that it
creates or is likely to create a hole or depression in the cap which could allow rain water
to infiltrate the cap, the tree ball should be removed and the hole/depression filled with
suitable soil, graded, compacted, and seeded to promote runoff and prevent ponding.

 Any waste unearthed or excavated during tree removal or maintenance activities shall be
transported to a permitted solid waste disposal facility for proper disposal, and the cap
shall be properly repaired.

 All trees to remain in place should have the lower limbs removed up to a height of six
feet (6’) measured at a distance of four feet (4’) from the trunk, to allow for easy
inspection and access for cap maintenance activities.

 Landfill edge of waste markers shall be maintained, and a path around the edge of waste
shall be kept free of brush to allow for inspection of edge-of-waste markers and
unobstructed passage around the landfill.

3.5 Groundwater Monitoring System
Groundwater Monitoring will continue at the facility throughout the duration of the post-closure
care period in accordance with the facility’s Groundwater Monitoring Plan. A copy of the
Groundwater Monitoring Plan is maintained at the Burke County General Services Office and
available to NCDEQ for their review.

Landfill personnel shall be aware of the location of all groundwater monitoring wells to prevent
accidentally damaging them with equipment. Any damage will be repaired appropriately. All
existing groundwater monitoring wells will be maintained. Site Plan is included in Appendix 2.

Minor damage to groundwater monitoring wells observed during inspections or sampling events
shall be repaired as soon as possible. If major damage or contamination is suspected, a
professional geologist shall be retained to evaluate the condition of the well. If the well must be
replaced, the old well will be abandoned in accordance with the facility’s Groundwater
Monitoring Plan. Well abandonment and replacement shall adhere to NCAC 15A Subchapter 2C
Well Construction Standards.

Groundwater monitoring at the East Burke Landfill is completed in accordance with the
monitoring requirements of Rule .0600 of the NCSWMR. Groundwater samples are collected
semiannually. Four active groundwater monitoring wells comprise the groundwater monitoring
network at the East Burke Landfill. The current compliance network consists of the monitoring
wells MW-1 (background), MW-2, MW-3, and AMW-1.

3.6 Landfill Gas Monitoring System
Landfill Gas Monitoring will continue at the facility throughout the duration of the post-closure
care period in accordance with the facility’s Landfill Gas Monitoring Plan (LGMP). A copy of
the LGMP will be maintained at the Burke County General Services Office and available to
NCDEQ for their review.

The LGMP will serve as a guidance document for collecting and monitoring of landfill gas at the
East Burke Landfill. Landfill gas will be monitored semiannually to ensure that methane
concentrations do not exceed the regulatory limit at the facility boundary. The LGMP was
prepared in accordance with the NCDEQ-SWS Landfill Gas Monitoring Guidance, to assure
performance standards are met and to protect public health and the environment. The current
compliance network consists of the landfill gas monitoring probes GP-1, GP-2, GP-3, GP-4,
GP-5, and GP-6. These monitoring probes were installed in June 2015.

Landfill personnel will be aware of the location of all landfill gas monitoring wells to prevent
accidentally damaging them with equipment. Any damage will be repaired appropriately. All
existing landfill gas monitoring wells will be maintained. A Site Plan showing the gas
monitoring locations is included in Appendix 2.

Minor damage to landfill gas monitoring wells observed during inspections or sampling events
shall be repaired as soon as possible. If major damage is suspected, a professional geologist will
be retained to evaluate the condition of the well. If the well must be replaced, the old well will
be abandoned in accordance with the facility’s LGMP. Well abandonment and replacement shall
adhere to NCAC 15A Subchapter 2C Well Construction Standards and the NCDEQ-SWS
Landfill Gas Monitoring Guidance.

4.0 POST-CLOSURE LAND USE
The County currently operates an active solid waste collection convenience center at the entrance
of the East Burke Closed Landfill. Part of the convenience center paved area lies over a portion
of the closed waste unit. No other active post-closure uses are planned for the property. No uses
are expected to interfere with the regulated post-closure care activities.

5.0 TERMINATION OF POST-CLOSURE CARE
5.1 PCC Certification
Following completion of the post-closure care period for groundwater and landfill gas
monitoring, and final cover system maintenance, Burke County may submit to NCDEQ a
certificate, signed by a registered professional engineer, verifying that post-closure care has been
completed in accordance with the post-closure plan and petitioning for termination of some or all
post closure activates. The certificate shall be accompanied by an evaluation, prepared by a
professional engineer licensed in the State of North Carolina and signed by the owner or
operator, assessing and evaluating the landfill's potential for harm to human health and the
environment in the event that post-closure activities such as groundwater monitoring, gas
monitoring, final cover system maintenance, and/or leachate management are discontinued.

5.2 NCDEQ Evaluation
To determine whether the post-closure care period may be decreased, increased, or terminated,
the NCDEQ may consider the following areas when reviewing the facility’s certification and
evaluation:

 Groundwater Monitoring;
 Landfill Gas Monitoring;
 Final Cover System Maintenance;
 Leachate Issues;
 Additional Post-Closure Care requirements contained in the facility’s permit
or approved Post-Closure Care Plan; and/or
 Other NCDEQ programs, e.g., air and water permits.
