Alternative Cover Material – Soil Equivalent Foam
Demonstration Report and Revised Operation Plan
Dear Mr. Hammonds:
On behalf of Cumberland County (County), CDM is pleased to submit a Demonstration Report
and revised Operation Plan that incorporates one additional alternative cover material (ACM),
soil equivalent foam, for approval from the North Carolina Department of Environment and
Natural Resources Solid Waste Section (NCDENR SWS). The intent of this report is to obtain
approval for the option to use the above mentioned ACM on a full‐time basis, under acceptable
weather conditions.
The Demonstration Report has been prepared in accordance with the NCDENR SWS draft ADC
guidance. Attachment 1 includes ACM Performance Evaluation Forms with accompanying
photo‐documentation for each day the ACM was used. The forms also provide approximate size
of application and quantity of foam used during each application. Additionally, a summary
sheet is included, which details the demonstration period and identifies Sundays and days when
ACM was used. For the demonstration period, 55 days were utilized for ACM use. This excludes
rain days, Sundays, and high wind days when ACM could not be used. Thusly, ACM was used
approximately half the time during the demonstration period. The evaluation forms and
accompanying photos indicate that the ACM’s performance in the control of vectors, odors,
litter, scavenging, and erosion and overall appearance was effective.
A revised Operation Plan is required in conjunction with the Demonstration Report (see
Attachment 2). In an effort to help expedite the plan modification review process, only Section

modified. A permit modification fee will be provided under separate cover, upon the County’s
receipt of an invoice from the NCDENR SWS.
If you have any questions regarding the details of this submittal, or need any additional
information, please contact me at 919‐787‐5620.
Very truly yours,

Facility Operation Plan Modification
Operation Plan - Section 6
A 6-1
Section 6
Cover Material Requirements
6.1 Daily Cover
In accordance with 15A NCAC 13B .1626 (2), the operator of MSWLF units must cover
disposed solid waste with six inches of earthen material (or alternative daily cover
(ADC) approved by the Solid Waste Section) at the end of each operating day, or at
more frequent intervals if necessary, to control disease vectors, fires, odors, blowing
litter, and scavenging. The daily cover must:
be capable of covering solid waste after it is placed without change in its properties
and without regard to weather;
be noncombustible; and,
not include rock fragments that are greater than six inches in diameter.
6.1.1 Wet Weather Operations
During wet weather, the County will develop a wet weather working face. The wet
weather working face will be kept as small as possible. At the end of disposal
operations, the County will cover in accordance with Section 6.1.
6.2 Intermediate Cover
In accordance with 15A NCAC 13B .1626 (2), the owner or operator of all MSWLF
units must place 12-inches of intermediate cover on all areas which will not have
additional waste placed on them for 12 months or more, but where final termination
of disposal operations has not occurred. The composition standards of intermediate
cover shall be the same as for daily cover in addition to being capable of supporting
the germination and propagation of vegetative cover.
6.3 Alternative Cover – Posi-Shell
The Posi-Shell Cover System is approved for use as an ADC. Posi-Shell is a
noncombustible blend of recycled materials. It will be used as an alternative daily
cover on waste disposed of at the Subtitle D landfill, if needed. Posi-Shell provides a
thin cover that hardens over the covered waste surface.
6.3.1 Cover System Description
Each Posi-Shell batch utilizes the following materials and respective quantities:
Two 100-pound bags of Posi-Pak;
1,000 pounds of Portland Cement;
6 tons of Fly Ash; and
Section 6
Cover Material Requirements
A 6-2
1,100 gallons of liquid.
One batch of posi-shell, as defined above, provides coverage for approximately 4,000
square feet at an application thickness of ¼-inch.
6.3.2 Cover System Application
Application of the posi-shell will generally follow the manufacturer’s
recommendation and will employ the following minimum procedures:
The posi-shell will be applied in two different directions to avoid spray shadow;
The posi-shell will be applied at the end of each working day;
The posi-shell surface will be visually inspected on a daily basis for exposed waste
and/or inadequate coverage.
The application of posi-shell during heavy rain events will be minimized. If posi-
shell is applied during periods of heavy rain, the surface will be visually inspected
following the rain event for exposed waste or inadequate coverage.
Areas of exposed waste and/or inadequate coverage will receive an additional
application prior at the end of the day.
6.4 Alternate Cover - Soil Equivalent Foam
Soil Equivalent Foam (AC-667SE) is proposed as an ADC (See Appendix E for the
Manufactures Usage Guide) on waste disposed at the Subtitle D landfill. AC-667SE
Soil Equivalent Foam provides a thick, long-lasting, viscous foam barrier for
immediate control of foul odors, blowing litter, disease vectors and scavengers over
the waste surface.
6.4.1 Properties of AC-667SE
The properties of each component of AC-667SE are presented in the Manufacturer’s
Usage Guide in Appendix E.
6.4.2 Cover System Description
As described in the Manufacturer’s Usage Guide, the application rate for short-term
coverage (overnight cover for daily cover operations) is 60 GPM liquid flow rate. One
gallon of concentrate diluted with 6.5 gallons of water will yield 80 square feet of
foam at a depth of 3”. Using the figures provided in section 6.4.3 a daily working face
of approximately 6500 square feet would require a 600 to 700 gallon batch.
Based on 700 Gallons the following quantities would be required for one batch:
606.6 gallons of water,
Section 6

A 6-3
93.3 gallons of Foam,
6.4.3 Cover System Application Procedures
Application Procedure
Application of the AC-667SE will generally follow the manufacturer’s
recommendation and will employ the following minimum procedures:
The Foam will be automatically applied in two different directions to avoid spray
shadow or wind dispersion through the use of a bi-directional spray bar.
The Foam will be applied at the end of each working day;
The Foam surface will be visually inspected on a daily basis for exposed waste
and/or inadequate coverage.
Areas of exposed waste and/or inadequate coverage will receive an additional
application prior to operations ending for that day.
Maximum Daily Area Coverage
Based on the Facility Plan:
Annual waste disposal rate (MSW only) = 165,702 ton/years
Operating days per year = 310 days
Approximate daily waste disposal rate = 540 tons
In-place density = 1,155 pounds of MSW per cubic yard
Daily cubic yards disposed = daily waste disposal rate / in-place density = 935 yd3
or 25,250 ft3
The working face will be restricted to the smallest area feasible. The working lift is
typically 4 feet high. Based on a working lift thickness of 4 feet, the working face area
is 6,310 square feet, which is equal to the daily coverage area.
Daily Depth and Quantity to be Applied
3” manufacturer recommended depth.

Material and Equipment Storage
Rusmar AC667-SE (soil equivalent) Foam will be stored in the Rusmar supplied
model BSD7000 (bulk storage device).
Wet Weather Operation
The application of AC-667SE during heavy rain events will be minimized. If AC-
667SE is applied during periods of heavy rain, the surface will be visually inspected
following the rain event for exposed waste or inadequate coverage.
Contingency Plans
If, for any reason, the County cannot use AC-667SE as ADC material, soil or Posi-shell
will be used.

6.4.4 Sampling Procedures
Since the AC-667SE is considered inert, free of petroleum and VOC’s, additional
leachate sampling will not be performed.

Foaming Recommendations
•Whenever possible foam in the straightest possible path.
•Foam duration is a function of dilution and depth. Overnight
coverage should be a minimum of 3”. Longer durations and rain
forecasted should be a minimum of 6” at the proper dilution ratio.
•To ensure proper operation it is recommended that the Foamers
should be “blown out” for a minimum of 5 minutes at the end of
each usage.
