I. INTRODUCTION AND BACKGROUND
This transfer station closure plan has been created on behalf of the Lenoir County Department of Solid
Waste for the Lenoir County Solid Waste Handling and Transfer Facility (Permit No. 5405T-TRANSFER-
1998). Closure activities for this facility will be conducted in agreement with this plan, the North Carolina
Division of Waste Management Rules, and generally sound environmental and waste management
practices.
The Municipal Solid Waste (MSW) Transfer Facility transports waste from this facility to the East Carolina
Environmental Regional Landfill, a lined waste management facility operating under Permit No. 0803-
MSWLF-1993, located in Aulander, NC, Bertie County. Closure of the transfer station will commence at
such time as determined by Lenoir County, and in conformance with this plan.

IV. FACILITY DESCRIPTION
The main MSW transfer structure is a metal building constructed on a concrete slab and retaining wall,
which enclosed on three sides, keeping one open facade that provides accessibility for incoming vehicles.
One of the enclosed sides provides an entrance for service vehicles to the tipping floor. The tipping floor
encompasses an area of approximately 5,850 square feet (75 feet by 78 feet). Transfer trailers are positioned
to the rear of the facility in a loading bay below the tipping floor.
Incoming loads are discarded onto the concrete tipping floor where they are compacted into the transfer
trailer located on the lower level. Leachate that is generated from normal activities and from regular
washing or pressure washing of the tipping floors is collected through drains in the lower -level floor. These
drains empty into the onsite holding tank which is pumped out by a licensed septage hauler for disposal at
the Kinston Wastewater Treatment Plant (WWTP).
V. SOURCE, TYPES, AND QUANTITIES OF WASTE
The MSW handling and transfer facility is used solely for the handling and conveyance of municipal solid
waste generated within Lenoir County from residential, commercial, and industrial sources. The Facility
only accepts solid waste as defined in G.S. 130A — 290(35). Any hazardous, liquid, or other prohibited
materials found in the waste stream shall be removed and held for proper disposal. The waste is transferred
to the site in publicly and privately owned vehicles of various types and sizes.
Between July 1, 2021 through June 30, 2022, 29,293.26 tons of MSW was accepted at the Lenoir County
Transfer Station, which equates to approximately 93.9 tons per day based on a five -and -a -half -day work
week. This rate is expected to remain relatively constant relative to population growth. Thus, a proportional
increase in waste quantities should be expected as Lenoir County's population increases.
VI. CLOSURE PLAN
The following describes the closure process for the Lenoir County transfer station once a decision is made
to cease operations. The facility will be properly closed in accordance with the requirements of 15A NCAC
13B .0406.
A. Description of Closure Activities
Once a decision has been made to close the Lenoir County Transfer Station, a written notification of the
closure will be submitted to the NCDEQ Division of Waste Management (DWM) no less than ninety (90)
days prior to the cessation of waste acceptance at the facility. All closure activities will be conducted in
accordance with the Closure Plan and in accordance with 15A NCAC 13B .0406.
Closure activities will begin no later than thirty (30) days after the receipt of the final waste load, and will
include removal of remaining solid waste, closure of the leachate collection system, and securing the
premises. Closure activities will be completed within 180 days after beginning closure activities.
During closure, all remaining wastes that will not be recycled, will be removed for proper disposal at an
approved disposal location, currently the East Carolina Environmental Regional Landfill. Recyclable
wastes will be removed and disposed of at an approved recycling facility, currently anticipated to be the
same facilities that accept recyclable materials from the Lenoir County Transfer Station.
N
• Lenoir County accepts used tires daily. Tires are stacked by the public into the storage trailer. Once
the facility is closed, any remaining tires will be placed into the remaining trailers and taken to the
contracted tire recycling firm for final disposal/recycling.
• Used lead -acid batteries are collected in a designated location and are stored on a wooden pallet
adjacent to the maintenance building. All remaining lead acid batteries will be processed for
recycling by the contract vendor and the pallets will be scrapped and ground with other pallets
recycled on site.
• Used oil is collected and stored in an aboveground 500-gallon steel storage tank located near and
to the North of the maintenance building, until disposal. All remaining used oil will be removed
by the used oil contract vendor and the steel tank cleaned and scraped.
• Televisions, monitors, computer equipment, and other misc. electronics are placed on pallets or in
Gaylord boxes at the electronics recycling area, and will be picked up for disposal/recycling by the
contract vendor.
• White Goods, which contain Freon, are collected by the facility and stored in one designated area
in the metal storage area. Freon will be removed from all remaining white goods as applicable, and
the white goods will be recycled by a contract vendor. Other forms of scrap metal will be collected
at the designated area and removed for final disposition by a contract vendor along with the white
goods.
All remaining wastes that will not be recycled, will be removed for proper disposal at an approved disposal
location, currently the East Carolina Environmental Regional Landfill. Any solid waste located on the
facility grounds including wind-blown liter and accumulations of waste within the transfer station building
and loading bay area, will be removed and disposed of in transfer trailers for final disposal at the referenced
landfill.
The transfer station building including the side walls, push walls, tipping floor and loading bay area will be
pressure washed once all solid waste has been removed from the facility. Leachate from the pressure
washing activity will be collected in the leachate collection system and removed for proper disposal. As
noted above, the transfer station structure is enclosed on three (3) sides, and pressure washing activities
may necessitate use of a lift to reach to upper elevations of the structure. It is anticipated the metal structure
will remain at the facility at the time of closure until such time as the County decides whether it can be
repurposed for some other use, therefore, no additional closure costs other than pressure washing are
anticipated. Access to the loading bay from the tipping floor will be secured with fencing or in some other
manner to prevent a fall into the loading area by anyone at the facility, or wildlife.
Leachate from the pressure washing activity will be collected in the leachate collection system and removed
for proper disposal. It is anticipated the pressure washing activities may require multiple mobilizations and
several days for each mobilization to complete the work. Potential work stoppages may occur due to the
leachate storage tank filling up, which will require pumping and hauling of the leachate for disposal.
The leachate collection system consists of a number of drains in the bottom of the loading bay floor,
connected to a series of pipes that collect and direct leachate to a 1,500-gallon concrete on -site storage tank.
Once all remaining solid waste has been removed from the transfer station and the station has been pressure
washed, any leachate remaining in the storage tanks will be pumped and removed for disposal at an
approved disposal facility, currently the Kinston WWTP. Lenoir County anticipates the contractor currently
responsible for pumping and hauling leachate, or another contractor as determined by Lenoir County, will
remove all remaining leachate from the tank for disposal. The drains, catchments, and piping connected to
the leachate collection tank, as well as the tank, will also be cleaned through pressure washing or other
appropriate means to remove residual leachate residues. Any and all remaining leachate will be pumped
and disposed of at an appropriate disposal facility.
Upon removal of the remaining leachate, all drains connected to the leachate collection system will be
plugged in a manner such that storm water or other liquids cannot enter the leachate collection system.
Leachate piping will be removed and disposed of as solid waste at an approved landfill and the leachate
collection tank will either be removed for disposal, crushed in place or filled with a flowable fill to prevent
the tank from being reused. At this time the County anticipates that the tank, once emptied of leachate and
residue, will be filled with flowable fill or concrete to prevent it from being used.
The facility office and scale house will be emptied and secured against unauthorized entry. Lenoir County
may retain the office in the event the property is repurposed for another use. The facility grounds will be
secured by a fence and locking gate in a manner to preclude easy accessibility to the property. Appropriate
signage will be placed at the entrance to inform residents the facility is closed.
B. Closure Schedule
The closure schedule will be as follows:
1. Lenoir County will send written notice to the DWM no less than ninety (90) days from the date the
facility anticipates receipt of the last load of solid waste.
2. Closure activities will begin within thirty (30) days from receipt of the last load of solid waste.
3. Within 180 days, Lenoir County will complete the closure of the transfer station.
4. Upon completion of the closure, Lenoir County will send a written notification to the DWM of the
closure and how the facility was closed for placement in the operating record.
5. Lenoir County staff will be available for any inspection deemed necessary by the DWM.
C. Corrective Action
Lenoir County will undertake any corrective action deemed necessary by the DWM in accordance with
15A NCAC 13B .0406(c). Specifically, Lenoir County will conduct any required groundwater and surface
water monitoring determined to be necessary and after consultation with the DWM staff, in accordance
with 15A NCAC 13B .0405(a)(2). Monitoring and corrective action, if required, will continue as post
closure care until the DWM authorizes termination of any required activities.
Because there is currently no post closure care associated with this transfer facility due to impacts to either
groundwater or surface water resources, no costs have been provided, since these costs would be highly
dependent upon the nature and extent of the monitoring and/or corrective actions needed, and the duration
of those activities. In the event post closure care costs associated with the above are required, Lenoir County
will amend the closure plan to include the estimated costs for the duration of the post closure care, and to
ensure compliance with 15A NCAC 13B .1800.
In the event the DWM requires post closure care monitoring or corrective cation, or Lenoir County elects
to leave the leachate collection system and tank in place for future use, the County will submit to the DWM
a notice that the site has been recorded with the Register of Deeds that will include the information
stipulated in 15A NCAC 13B .0406(b)(4). Lenoir County may request removal of land use restrictions in
accordance with 15A NCAC 13B .0406 (d).
D. Closure Cost Estimate
Costs associated with the final closure of the transfer station were estimated based on information available
at the time of this closure report. It is currently unknown how much waste will need to be removed from a
facility in the event of a closure. It is assumed that since this is a County owned facility, that it will continue
to operate and receive/recycle solid waste up to the time of closure when no additional waste will be
received.
Assumptions were made that there will be a need to remove some additional wastes from the facility
grounds as part of the "housecleaning" activities, therefore, costs were estimated based on these
assumptions and current rates for particular activities. For the purposes of closure, it was assumed that up
to three (3) transfer trailers would be needed to remove any remaining wastes not disposed of by contract
vendors, and that accumulated after the date the last load of wastes were to be received from the public as
noted in B.1 above.
Current costs for a 40 yd. transfer trailer are approximately $1,000 per load inclusive of tipping fees for a
40 yd. trailer filled and compacted to the degree possible, therefore the estimated cost for three (3) trailers
is $3,000. An estimate of $5,000 was used as a buffer for waste disposal purposes in the event additional
waste removal is necessary, including the removal of recyclable materials if a contract vendor is not
available.
Pressure washing costs are variable and dependent upon the scope of cleaning activities, whether there is a
need for a lift to reach the higher elevations of a structure and the amount of water generated during cleaning
activities. Assumptions were made that the pressure washing activities may require at least two (2)
mobilization and cleaning operations, one for the facility and one for the leachate collection and storage
system. To the extent possible, scheduling attempts will be made to reduce the time on site and number of
mobilizations.
The Lenoir County facility is closed on three (3) sides and has elevated exterior walls that may require use
of a lift. There is also a loading bay located below the elevation of the tipping floor that will require care
when pressure washing activities are occurring. Costs associated with multiple mobilizations, the rental of
a lift and the scale of the structure are estimated at $1,000 per mobilization of pressure washing and lift
equipment and between $5,000 - $7,500 per pressure washing event (week duration), with up to two (2)
events estimated for the closure, with total costs ranging from $12,000 - $17,000.

There is one (1) leachate storage tank, with a 1,500 gal. capacity. Current disposal rates are estimated at
$300 - $1,000 per 1,500 gal. Typical hauling rates may range from $0.03 - $.10/gal on average, and hauling
depending on the distance hauled to the nearest disposal facility. Assuming three (3) pumping events as a
worst -case scenario, the total cost for leachate disposal would be approximately $3,000.00.
Decommissioning costs for the leachate collection system and tank will vary depending on whether the
tanks are crushed in place, filled with flowable fill or physically removed from the ground (the higher cost
option). The estimated cost may vary between average of $10,000 for filling in place to as much as $50,000
for removal of a tank and backfilling the excavation. Lenoir County would propose to abandon the concrete
leachate tank in place and filling the tank with flowable fill once cleaned of leachate and residue. The
leachate collection system piping and drain will be filled with concrete to prevent accumulation of
stormwater in the piping and tank. In the event piping is removed, it will be disposed of at the landfill. Costs
are estimated to be approximately $20,000 to clean and fill the tank in place, and plug or remove the leachate
collection drain and piping.
Administration costs, if performed by a contracted firm as opposed to County staff, and assuming 20 hours
of project oversight per week for six (6) months may range from $45,000 - $65,000. Travel time and per
diem costs will drive up the administration costs by approximately $5,000 - $10,000. This estimate is
inclusive of providing the required notification to the NC DEQ, arranging for various contractors including
bid solicitation and contractor selection, and overseeing the closure activities. Costs may be less depending
upon the staff level used for the project oversight, the actual amount of time needed on sight, and the amount
of travel and per diem needed. For the purposes of closure, an estimate using the lower amounts for travel
and per diem suggests the administration costs would be approximately $50,000.
Closure cost estimates, including any costs associated with post closure care monitoring and/or corrective
action are not provided. In the event post closure care monitoring and corrective action is required by the
DWM, costs will be revisited as required to ensure financial assurance requirements are maintained, and
the closure plan will be modified to include post closure care requirements.
Estimated costs associated with the closure of the facility include the following:
1. Mobilization/demobilization -
$2,000

E. Post Closure Care
There is currently no post closure care associated with this facility due to no known impacts to either
groundwater or surface water resources. In the event the DWM requires groundwater and/or surface water
monitoring, or corrective action at this facility in accordance with 15A NCAC 13B .0405(a)(2), additional
information associated with the post closure care will be provided. In addition, cost estimates will be
provided for any post closure care activities including the anticipated duration of time for post closure care.
In the event the DWM requires post closure care monitoring or corrective action, or Lenoir County elects
to leave a leachate collection system and tank in place for future use, the County will submit to the DWM
a notice for the site that has been recorded with the Register of Deeds, that will include the information
stipulated in 15A NCAC 13B .0406(b)(4)(A-C) as follows:
• The notice shall be discoverable during a title search for the site property deed.
• The notice shall be in accordance with G.S. 130A-310.71(e) or G.S. 14313-279.10.
• The notice shall notify any potential purchaser of the property that the land has been used as a solid
waste management facility and its use may be restricted by the Division
Lenoir County may request in writing removal of land use restrictions in accordance with 15A NCAC 13B
.0406 (d).
F. Record Retention
Records of the closure activities, final disposition of all wastes including recyclable wastes and leachate,
will be retained for a minimum of five (5) years or as otherwise specified by 15A NCAC 13B .0405(d).
