Alexander County

Construction and
Demolition Landfill

Operations Plan

Revised 1/26/16 and 5/5/16
1.1 Introduction

Alexander County will continue to operate a Construction and Demolition Landfill (C&DLF) within
the permitted boundaries and upon closed sections of the present municipal solid waste landfill.
The section are limited to areas that stopped receiving waste in 1998 and have two feet of final
cover.

The C&D Landfill will receive the following solid waste:

1. Land clearing debris as defined in G.S. 130A-290, specifically, solid waste which is
generated solely from land clearing activities, such as stumps, trees, etc.;

2. Inert debris from any source that is defined as solid waste which consists solely of
material that is virtually inert, such as brick, concrete, rock and clean soil;

3. Asphalt in accordance with G.S. 130-294(m);

4. Construction and demolition debris defined as solid waste resulting solely from
construction, remodeling, repair or demolition operations on pavement, buildings or
other structures (includes glass, vinyl, plastic, laminates, plumbing fixtures, etc.);

5. Construction materials, that could or would be part of any construction, remodeling,
repair or demolition of pavement, buildings or other structures, from industrial and/or
commercial sources within the County such as, but not limited to, shingles from
shingle manufacturers, mobile home debris from mobile home manufacturers, lumber
from lumber yards, scrap materials from cabinet manufacturing facilities and furniture,
pre-fabricated building structure components such as joists and any other scrap
materials; and,

6. Pallets from any source.

Yard Waste as defined in G.S. 130A-290, shall not be disposed in the landfill area. However, yard
trash, along with land-clearing debris, may be accepted for processing in a permitted Yard Waste
Composting Area.

Soil cover will be placed at least once a week. (See cover requirements under operational
requirements).

The County will implement a program at the landfill for detecting and preventing the disposal of
hazardous and liquid wastes. The program consists of random inspection of incoming loads at a
minimum of 1% of the weekly traffic. Landfill personnel will be trained to recognize hazardous
and liquid wastes. Records will be kept on the training and the inspections.

The County will monitor for explosive gases at landfill structures and the perimeter of the landfill.
The concentration of methane gases generated by the landfill cannot exceed 25 percent of the
lower explosive limit for methane in the structures, and it cannot exceed 100 percent of the lower
explosive limit for methane of the landfill property boundary. If methane gas is found to exceed
the acceptable limits at either the property boundary or landfill structures, it is the County’s
responsibility to do the following:

1. Immediately take all necessary steps to ensure protection of human health, i.e. no
smoking, temporarily abandon the structure and notify the Division of Solid Waste
Management.

2. Within seven days of detection, place in the operating record the methane gas levels
detected and a description of the steps taken to protect human health; and

3. Within 60 days of detection, implement a remediation plan for the methane gas releases,
place a copy of the plan in the operating record, and notify the Division of Solid Waste
management that the plan has been implemented. The plan will describe the nature and
extent of the problem and the proposed remedy.

Off and on site erosion will be controlled through erosion control structures and devices.
Provisions for a vegetative ground cover sufficient to restrain erosion will be accomplished within
30 working days or 120 calendar days upon completion of any phase of landfill development.

The County will record and retain at the landfill an operating record of the following information:

(1) Inspection records, waste determination records, and training procedures;

(2) Amounts by weight of solid waste received at the landfill;

(3) Gas monitoring results and any remediation plans;

(4) Any demonstration, certification, findings, monitoring, testing or analytical data
required for surface and groundwater monitoring;

(5) Any monitoring, testing or analytical data required for closure or post-closure;

(6) Any cost estimates and financial assurance documentation.

All information contained in the operating record will be furnished upon request to the Division of
Solid Waste Management or be made available at all reasonable times for inspection by the
Division.

Ground and surface water will be sampled and analyzed according to Subtitle D Appendix I
detection monitoring requirements. The monitoring frequency for all Appendix I detection
monitoring constituents will be at least semiannual during the life of the facility (including closure)
and the post-closure period. A minimum of four independent samples from each well
(background and down gradient) will be collected and analyzed for the Appendix I constituents
during the first semiannual sampling event. At least one sample from each well (background and
down gradient) will be collected and analyzed during subsequent semiannual sampling events.

If the County determines that there is a statistically significant increase over background for one
or more of the constituents listed in Appendix I at any monitoring well at the relevant point of
compliance, the County will, within 14 days of the finding, report to the Division of Solid Waste
and place a notice in the operating record indicating which constituents have shown statistically
significant changes from background levels. The County will establish an assessment monitoring
program within 90 days. The County may demonstrate that a source other than the landfill
caused the contamination or that the statistically significant increase resulted from an error in
sampling, analysis, statistical evaluation, or natural variation in ground-water quality. A report
documenting these demonstrations will be certified by a Licensed Geologist or Professional
Engineer and approved by the Division of Solid Waste. A copy of this report will be placed in the
operating record. If a successful demonstration is made, documented, and approved by the
Division, the County may continue detection monitoring. If after 90 days, a successful
demonstration is not made, the County will initiate an assessment monitoring program.
1.2 Operational Requirements

1. Waste Acceptance and Disposal Requirements

a. The Construction and Demolition Landfill (C&DLF) will only accept those solid
wastes generated within Alexander County and which it is permitted to receive.
The County will notify the Division within 24 hours of attempted disposal of
any waste the landfill is not permitted to receive.

b. Asbestos waste will be managed in accordance with 40 CFR 61. The regulated
asbestos waste will be covered immediately with soil in a manner that will not
cause airborne conditions and will be disposed of separate and apart from other
solid waste, as:

i. in a defined isolated area within the foot print of the landfill, or

ii. in an area not contiguous with other disposal areas. Separate areas
will be designated so that asbestos will not be exposed by future land-
disturbing activities.

inches of earthen material when the waste disposal area exceeds one-half acre
and at least once weekly. Cover must be placed at more frequent intervals if
necessary to control disease vectors, fires, odors, blowing litter, and
scavenging. A notation of the date and time of the cover placement must be
recorded in the operating record, as specified in Paragraph 10 in this section.

b. Except as in Subparagraph (c), areas which will not have additional wastes
placed on them for three months or more, but where final termination of disposal
operations has not occurred, will be covered and stabilized with vegetative
ground cover or other stabilizing material.

c. Alternative material or an alternative thickness of cover may be used, if the
County demonstrates that the alternative material or thickness controls disease
vectors, fires, odors, blowing litter, and scavenging without presenting a threat to
human health and the environment, and is approved by the Division.
