Subject: Major Permit Modification
Request for Daily Tonnage Increase
Great Oak Landfill, Permit No. 7607-MSWLF-2015
Randolph County
Dear Mr. Chao:
On behalf of Randolph County and Waste Management of Carolinas, Inc., SCS Engineers, PC submits
this request to modify the Facility Permit to change only the daily tonnage rate from 2,000 tons per
day to 4,000 tons per day. No other changes are proposed at this time and all remaining parts of
the Permit to Construct (PTC) Application for the existing permit are unchanged.
To facilitate this change, the following are enclosed:
• Revised Franchise Agreement (Attachment A)
• Permit to Construct Application Great Oak Landfill cover sheet (Attachment B). A revision
date and footnote were added.
• Revised Facility Plan pages 9 and 11 to reflect the revised daily tonnage. (Attachment C).
The Facility Plan (Section 3 of the PTC Application) for the Great Oak Landfill was
originally submitted February 2015 and revised September 2015.
• Revised Engineering Plan page 17 and Appendix II to reflect the revised daily tonnage
(Attachment D). The Engineering Plan (Section 4 of the PTC Application) for the Great
Oak Landfill was originally submitted February 2015 and revised September 2015.
In addition, WM is currently working with Randolph County and NCDOT to post signage along
approved access routes.
During the process of completing this tonnage increase request, we became aware of an error in the
original PTC and subsequent Permits to Operate. The Gross Capacity of the landfill stated in the
original PTC (January 19, 2016, pages 9 and 15) was actually the Net Airspace volume as defined in
Appendix II of the Engineering Plan. The corrected Gross Capacity volumes for each Phase of the
landfill are tabulated in the revised calculation provided in Attachment D.

2. WASTE STREAM
2.1 Types of Waste
The types of waste specified for disposal include household waste, commercial solid waste and
industrial solid waste as defined by 15A NCAC 13B .1602 of the Solid Waste Management Rules.
2.2 Disposal Rates1
The Great Oak MSWLF facility is currently permitted to receive an average daily intake and
disposal rate of 4,000 tons per day or a maximum daily intake and disposal rate of 5,500 tons
per day to account for times when intake rates peak, including periods when emergency debris management is required after floods, hurricanes, tornados or other such events. For an operating factor of 286 days per year, the annual disposal rate will be up to 1,144,000 tons per year. The disposal rate calculations are presented in the Engineering Plan.
Future disposal rates may vary due to the population, industrial, and commercial growth within the region, recycling efforts, and/or availability of other landfills or alternative waste disposal methods.
2.3 Service Area
Randolph County anticipates that the waste stream for the Great Oak MSWLF will be generated
from residents, agricultural facilities, commercial businesses, and industrial facilities within the State of North Carolina. No out-of-state waste will be accepted.
2.4 Procedures for Segregated Management
The landfill plans to accept typical waste streams for a fully permitted municipal solid waste (MSW) landfill in North Carolina, including:
1. Municipal Solid Waste (MSW); 2. Construction and Demolition (C&D) debris; 3. Waste water treatment plant (WWTP) sludge; 4. Asbestos containing material (ACM), properly packaged; 5. Commercial waste;
6. Industrial waste (solid, non-hazardous), a.k.a. special waste; 7. Shredded tires; 8. Off-spec food, animal carcasses (covered immediately for vector control); and 9. Non-regulated, non-infectious (treated) medical waste.
The Great Oak MSWLF will implement a load checking program to detect and discourage disposal at the facility of unacceptable waste [.1626 (1)(f)]. The load checker and the load checking program will include random inspections [.1626 (1)(f)(i)] as described in the Operations Plan, located in Section 7, Volume III of the Permit to Construct Application.
2.5 Equipment Requirements
The primary functions of heavy landfill equipment are as follows:
• Spreading and compacting solid waste,
• Excavating, hauling, and spreading cover material, and
• General site maintenance.

3. LANDFILL CAPACITY AND SOIL RESOURCES
3.1 Data and Assumptions
Landfill capacity calculations were performed for the Great Oak MSWLF from proposed
grading and closure plans using the anticipated annual disposal rate data presented previously in Section 2.2 of this Facility Plan. The gross capacity consists of the volume between the top of the liner protective cover and the top of the final cover.
Soil for construction, operation and closure of Phases 1-9 will be obtained from the excavation
of the landfill footprint as well as from on-site borrow areas as needed. Landfill capacity and soil quantity estimates are discussed in the following sections of this Facility Plan.
3.2 Operating Capacity1 The gross capacity of the proposed Great Oak MSWLF is approximately 38.4 million cubic yards. The net airspace volume is approximately 37,800,000 cubic yards. Assuming 4,000
tons per day, 286 days a year, and a utilization factor of 0.75 tons/yd3, the estimated airspace utilization rate is approximately 1,525,333 cubic yards per year and the resulting estimated life of Phases 1 through 9 is approximately 24.8 years.
In the table below are the estimated usable volumes and lifetimes of Phases 1-9:

9 4,392,158 2.88
TOTALS 37,801,001 24.78
3.3 Borrow and Required Soil Quantities
Based on the borrow soil evaluation presented in the Engineering Plan, about 5.5 million cubic
yards of soil will be required for construction, operation and closure of Phases 1-9 of the Great Oak MSWLF, while about 4.0 million cubic yards of soil will be generated during construction. Soil excess or deficit was estimated throughout the life of landfill Phases 1-9. There is a net deficit of soils during all events. The peak deficit of approximately 1.5 million cubic yards is during final closure.
There is anticipated to be a deficit of stockpiled soil after Phase 1 operations of approximately 66,000 cubic yards. It is anticipated that during this event, additional soil will be obtained from on-site borrow sources.

7. DESIGN ANALYSES
The Phase 1 area has been evaluated for compliance with the requirements set forth in the Rules. A
summary of the design analyses performed for the Phase 1 area is presented below and includes a
brief discussion of the analytical methods, critical conditions, and assumptions used in the evaluations. Copies of the individual calculations are provided in the appendices and are grouped into the following categories:
Appendix II: Landfill Capacity and Borrow Area Evaluation
Appendix III: Stability Calculations Appendix IV: Geosynthetics and Leachate Generation Calculations Appendix V: LCS/LDS Piping Calculations Appendix VI: Stormwater Management Calculations
Engineering Plan drawings can be referenced in Appendix I.
7.1 Landfill Capacity and Borrow Soil Quantities
7.1.1 Landfill Capacity1 The landfill capacity for the Phase 1 was estimated using the proposed grading and closure plans. The capacity of Phase 1, which consists of the airspace between the top of the protective cover soil and the top of final cover, was estimated to be on the order of 7,160,621 cubic yards. The net airspace volume for Phase 1 (measured between the top of the protective soil cover to the top of the intermediate cover) is approximately 6,978,960 cubic yards. Assuming 4,000 tons per day, 286
days a year, and a utilization factor of 0.75 tons/yd3, the estimated airspace utilization rate is approximately 1,525,333 cubic yards per year and the resulting estimated life of Phase 1 is approximately 4.58 years. At 3,000 tons per day, the estimated life of Phase 1 is 6.1 years.
The capacity Phases 1 through 9 is estimated to be approximately 38,414,398 cubic yards. The net airspace volume is approximately 37,800,000 cubic yards. Assuming 4,000 tons per
day, 286 days a year, and a utilization factor of 0.75 tons/yd3, the estimated airspace
utilization rate is approximately 1,525,333 cubic yards per year and the resulting estimated
life of Phases 1 through 9 is approximately 24.8 years. At 3,000 tons per day, the estimated life of Phases 1-9 is 33 years.
7.1.2 Borrow Soil Quantities
Soil for construction, operation, and closure of the Phase 1 area and future phases will be obtained
from the excavation of the landfill footprint. If sufficient material is not available, additional soil may be obtained from on-site borrow areas or off-site sources as needed. An evaluation of soil volumes available from site grading activities during construction and required for landfill operations and closure was performed.
Based on the proposed grading plan for the Phase 1 area and conceptual grading plans for future phases, the available borrow soil quantities were estimated for each phase. These volumes were in turn compared with the required soil volumes needed for general site filling during construction, protective cover soil, operational and intermediate soil covers, and final covers.

OBJECTIVE:
This calculation estimates the airspace and lifetime for the Great Oak Landfill. This calculation also provides a
comparison between on-site borrow soil supply and anticipated soil demand during operations and closure of
the Great Oak Landfill, and estimates potential stockpiling requirements.
METHOD:
The total landfill airspace and on-site borrow soil supply were estimated by creating three-dimensional surfaces
in AutoCAD Civil 3D 2015 to estimate volumes. Anticipated waste generation rates provided by Waste
Management of Carolinas, Inc. and Randolph County were used to estimate remaining landfill lifetime.
The comparison of soil demand to soil supply was evaluated by reducing the bank cubic yards excavated
volume by 20 percent to account for soil shrinkage.
ASSUMPTIONS:
Operations soil and intermediate cover needs = 10% net capacity
Shrinkage factor = 20% (Ref. 1)
Protective cover = 2 ft
Final cover = 2 ft
Airspace utilization factor = 762,667 cy/yr (AUF = (2,000 tons/day x 286 operating days per year)/0.75 tons/cy)
CALCULATIONS:
Step 1: Estimate landfill airspace and lifetime.
The approximate landfill airspace and lifetime was estimated by creating three-dimensional surfaces of the
proposed cover grade, the proposed subgrade, and the existing grade in AutoCAD Civil 3D 2015. The gross
airspace volume was estimated for each cell and phase by comparing the proposed protective cover and the
proposed intermediate cover grade.
The usable waste volume was estimated by deducting 10 percent of the net capacity due to operational and
intermediate soil cover. The estimated lifetime was evaluated by dividing the net volume by an assumed
airspace utilization factor of 762,667 cubic yards per year. The Phase 1 landfill airspace and lifetime was
estimated as shown in the following table:

The total estimated landfill lifetime for Phases 1 through 9 is 49.6 years.
Step 2: Evaluate borrow soil supply versus anticipated soil demand.
Generally, excess soil will be generated and stockpiled during the construction phase, and then utilized during
construction, operation, and closure of the landfill. The available amount of stockpiled soil will change during
the lifetime of the landfill as phases are constructed (generating soil), and operated and closed (requiring soil).
The soil supply and demand for assumed landfill events (such as phase construction, phase operation, phase
closure, etc.) were evaluated.

The unadjusted soil demand is shown in Table 3. The landfill grading phase operations were evaluated by
dividing the landfill operations for Phases 1 through 9 into 19 events (Events 1-19) as shown on Attachment 1.
Soil excess or deficit was estimated throughout the life of landfill Phases 1 through 9. There is a net deficit of
soils during all events. The peak deficit of approximately 1,470,179 cubic yards is during Event 19, final
closure.

Note that there is anticipated to be a deficit of total stockpiled soil after Event 1, Phase 1 operations of
approximately 65,858 cubic yards. It is anticipated that during this event, additional soil will be obtained from
on-site borrow sources.
DISCUSSION:
Based on soil material generation and demand estimates from S&ME’s experience, excess soil will be generated
during the Phase 1 construction (Event 1) which may be used during Phase 1 operations (Event 2).
For the Phase 1 operations condition where protective cover consists of soil, the volume of soil material demand
exceeds the volume of available stockpile material by as much as 65,858 cubic yards, and the total soil deficit
after the final closure is approximately 1,470,179 cubic yards. The net soil deficit will be obtained by
excavating in on-site borrow sources, such as in the vicinity of the borrow areas 1 through 3.
The estimated soil supply volume for the condition where protective cover consists of soil is presented in
Attachment 1.
It should be noted that the actual material volumes will vary from the estimated quantities presented based on
conditions encountered in the field and actual landfill operations requirements.
