LCID Landfill
Permit Modification Application – Reclamation Operations Plan
Permit No. 67-09

Dear Ms. Wilson:
On behalf of Onslow County (County), CDM Smith Inc. (CDM Smith) is pleased to submit the
following Permit Modification Application regarding the proposed land clearing and inert
debris (LCID) landfill reclamation operations at the County’s landfill facility. The
application includes the attached LCID Landfill Reclamation Operations Plan and associated
Permit Drawings.
The permit application documents were prepared in accordance with Solid Waste Section
direction by Mr. Ming-tai Chao on a conference call with Division of Energy, Mineral and
Land Resources, County and CDM Smith staff on March 20, 2017.
A waste characterization investigation was conducted at the LCID landfill to determine the
composition of the waste. Most of the characterized waste consisted of uncontaminated
dirt, organics, and tree limbs/stumps. Due to the large quantity of recoverable material,
reclaiming and re-establishing the LCID landfill was deemed a viable and feasible
management approach. The excavated material will be screened and used at the landfill
facility.
Since there are no permit modification or permit amendment terms in the current North
Carolina General Statutes for landfill reclamation, we understand that no permit fee is
associated with this review.

LCID Landfill - Reclamation Operations Plan
Section 1 - Introduction
Onslow County (County) disposes of land clearing and inert debris (LCID) at the permitted,
approximately 6-acre LCID landfill located south of the leachate storage tanks at the Onslow
County Landfill Facility. Based on the 2016 Airspace Analysis Report, the County has
approximately 4 years of remaining airspace capacity in Phase 5 of the LCID landfill which is the
final phase of development.
The County intents to reclaim the LCID landfill by excavating disposed material to proposed
bottom filling grades, screen the excavated material, and segregate and stockpile different types
of materials based on reuse potential. This would re-establish disposal airspace at the LCID
landfill which is in an ideal location in reference to the scalehouse and Subtitle D landfill.
A waste characterization investigation was conducted at the LCID landfill to determine the
composition of the waste. Most of the characterized waste consisted of uncontaminated soil,
organics, and tree limbs/stumps.
The purpose of this Reclamation Operations Plan is to present reclamation activities and includes:
· Introduction/Site Location
· Definition of the Product and Waste
· Reclamation Operations
· Material Stockpile Requirements
· Final Use of the Reclaimed Products
· Landfill Gas Monitoring
· Leachate Management
· Fire Potential and Response

LCID Landfill - Reclamation Operations Plan
Section 2 - Site Location
The LCID landfill is located south of the leachate storage tanks at the Onslow County Landfill
Facility as shown on the LCID Landfill Reclamation Project Drawings (Drawings). The facility is
located approximately seven miles northwest of Jacksonville along Meadowview Road (S.R. 1243)
and two miles southeast of Catherine Lake. The LCID landfill has a footprint of approximately 6
acres.

LCID Landfill - Reclamation Operations Plan
Section 3 - Operations
3.1 Definition of Product and Waste
CDM Smith previously conducted a waste characterization investigation at the LCID landfill. The
investigation indicated that the average composition of waste in the LCID landfill consists of
approximately 40.3% uncontaminated soil, 37.7% stumps/brush/limbs, and 19.2% organics.
Uncontaminated soil is characterized as soil that appears, upon visual observation, to be free
from contaminates such as oils, pesticides and other chemicals. Organics encountered largely
consisted of decaying leaves, bark and wood chips. The remaining percentage of material found
in the LCID landfill consisted of concrete, brick/tile, treated wood, plastic, metal and fabric.
“Product” is defined as organics and uncontaminated soil material that can be beneficially used at
the landfill for stabilization. Concrete may be segregated, crushed at a later date and used for
road stabilization.
“Waste” is defined as stumps, limbs, and large tree trunks. Other “waste” materials include
plastic, metal, brick, treated wood, etc. unsuitable for reuse. The remaining “waste” materials that
are suitable for disposal in a LCID landfill will be placed as the first lift in the reclaimed LCID
landfill.
3.2 Reclamation Operations
Before reclamation operations begin, erosion and sedimentation control measures will be
installed at the perimeter of the LCID landfill. Excavation of the LCID landfill will be a phased
approach in order to limit the area of disturbance at any given time, manage stormwater, and
allow disposal operations to continue. Containment berms will be built to management
stormwater and any perched stormwater that is within the LCID landfill mass.
When a portion of the LCID landfill reaches the proposed bottom filling grade, the area will be
stabilized with seeding. The phasing is presented in the Drawings.
Monthly soil cover will be provided for any areas of exposed, disposed LCID material (i.e., LCID
areas that have not been reclaimed).
Generally, the County will utilize landfill staff and equipment to conduct reclamation activities in
1-acre areas as shown on the Drawings. The reclamation project work is estimated to require up
to 6 months to complete. Depending upon the impact of daily landfill operations and staff
availability the project schedule may extend beyond 6 months.
Excavated material will be screened to separate soil and organics from larger tree stumps/limbs
and waste. Screened soil material will be either used directly on site by staff or placed in the
active borrow area. Stumps, tree trunks, and large branches will be stockpiled in the yard
waste/screening area as shown on Drawings. Other waste materials including plastic, metal, etc.
that are unsuitable for reuse and LCID landfill disposal will be disposed of in the Subtitle D

landfill. The remaining “waste” materials that are suitable for the LCID landfill will be placed as
the first lift in the LCID landfill. Excavated material final locations are shown on the Drawings.
3.3 Material Stockpile and Processing Requirements
The screened material, which will consist of organics and uncontaminated soil, will be either used
directly on site by staff or placed in the active borrow area. The active borrow area has adequate
stockpile storage. Large tree limbs and stumps will be stockpiled in the Yard Waste/Screening
Area, located west of the closed sanitary landfill. Unsuitable material/waste will be immediately
disposed of in the Subtitle D landfill located north of the LCID landfill. The yard waste stockpile is
shown on the drawings with estimated buildout volume to ensure adequate size and space.
3.4 Final Use of Reclaimed Material
The screened material will be used on-site for side slope stabilization and/or stockpiled for
partial closure construction projects. Tree limbs/stumps will be stockpiled and potentially
ground into mulch to be used at the landfill.
3.5 Landfill Gas Monitoring
During the waste characterization investigation, gas was not detected while excavating the test
pits. However, during LCID landfill reclamation activities, at least one staff will wear a landfill gas
(methane) monitoring device.
3.6 Leachate Management
Any perched stormwater (rainwater leached through LCID waste) encountered during
reclamation will be allowed to drain westward to containment berms within the LCID landfill
limits as shown on the Drawings. If evaporation and/or infiltration does not remove the
contained stormwater, the County may elect to pump and haul.
3.7 Fire Potential and Response
The fire potential is minimal because of the composition of the LCID landfill waste (i.e., mixture of
large debris and soil). However, the County will have continuous observation and the local fire
department emergency telephone number on-site. Additionally, the County has a 3,500-gallon
water truck on-site for use.
