Location

The proposed Jungo Disposal Site is located in the southern end of Desert Valley, approximately 30 miles west of Winnemucca, along the south side of Jungo Road and adjacent to the Union Pacific Railroad. The site is bounded by the Jackson Mountains to the west and northwest, the Antelope Range to the southwest, Alpha Mountains to the south and the Eugene Mountains to the southeast. The landfill will be located on a parcel totaling 634 acres, with the landfill located on 560 of those acres.

The location of the property is Township 35 North, Range 33 East, MDBM, Section 7.

The landfill boundary will be located 100 feet from the east, west and south parcel boundaries, and 200-300 feet from the north parcel boundary.

The Project

The Jungo Disposal Site will be a Class I Municipal Solid Waste Disposal Site. The facility will serve as a regional disposal site for Northern California and, if requested, Humboldt County, Nevada. Refuse will be delivered to the site by rail at an estimated rate of up to 4,000 tons per day. Although refuse from Humboldt County is disposed of at the Humboldt County Regional Landfill, the Jungo Disposal Site will accept waste from Humboldt County if the county so desires. Waste from Humboldt County would arrive at the site by truck.

Refuse will be delivered to an on-site rail yard adjacent to the landfill for loading/unloading of containers. The containers are steel-lidded containers specially designed for the hauling of refuse.


Proximity to Ground and Surface Water

The facility is located in the Desert Valley groundwater basin, with groundwater at approximately 60 feet below ground surface. The nearest surface water body is Rye Patch Reservoir, which is located 14 miles to the south of the Jungo Disposal Site in a separate and distinct groundwater basin.

Site Development

On-site ancillary facilities at the Jungo Disposal Site include:
  • Rail yard for unloading and loading of waste containers
  • Equipment maintenance shop
  • Administrative trailer
  • Break room trailer

Landfill Development

The Jungo Disposal Site is designed with 10 modules of approximately 56 acres each. The site will be constructed in phases, consisting of the construction of approximately 20 to 30-acres of the base liner at a time.

The landfill will also be closed in phases as the site developed.

Waste Received

The Jungo Disposal Site will serve as a regional disposal site for portions of Northern California and possibly Humboldt County. Although waste from Humboldt County is currently disposed of in the Humboldt County Regional Landfill, should the county so desire, the Jungo Disposal Site will accept local waste. Refuse from Northern California will be delivered to the site by rail. Refuse from Humboldt County would be delivered to the site by truck.

The majority of the waste received at the site is municipal solid waste derived from residential and commercial sources. Also received is construction and demolition debris, wastewater treatment sludge, asbestos-containing wastes, and shredded waste tires.

Typically, municipal solid waste from Northern California is processed to remove recyclable or compostable materials. In addition, a screening program exists to remove hazardous waste before it is loaded into rail containers.

Hazardous waste will not be accepted or disposed of at the site. All containerized loads delivered to the site will undergo inspection and waste exclusion screening, and all points of origin will be required to employ a hazardous waste exclusion program. At the Jungo Disposal Site, site personnel will be trained and required to visually inspect all incoming loads at the working disposal area and isolate any suspect materials.


Environmental Controls

The Jungo Disposal Site is designed with extensive systems of low-permeability containment systems, high permeability leachate controls to minimize leachate head on the liner, and a landfill gas collection and disposal system to control landfill gas. In addition, drainage controls will be implemented to prevent off-site run-on and run-off.


Base Liner System

The base liner system consists of a prescriptive composite liner system, in accordance with Nevada Administrative Code 444.681. The components of the base liner system, from top to bottom on the floor of the landfill are:
  • 2-foot thick operations soil layer
  • 1-foot thick gravel blanket for Leachate Collection & Removal System
  • Central leachate collection piping
  • 16-oz geotextile cushion
  • 60-mil high density polyethylene (HDPE) geomembrane
  • 2-foot thick compacted low-permeability soil liner

On the side slopes, the base liner system is comprised of the following components from top to bottom:
  • 2-foot thick operations soil layer
  • Geocomposite drainage layer
  • 60-mil high density polyethylene (HDPE) geomembrane
  • 2-foot thick compacted low-permeability soil liner

Leachate Control System

The landfill liner system design includes a blanket Leachate Collection & Removal System that has a high hydraulic capacity that is designed to collect leachate while minimizing leachate head build up on the liner.

On the floor of the landfill, the Leachate Collection & Removal System will consist of a one-foot thick gravel blanket with a 6 inch diameter HDPE drainage pipe located on the center of the flow-line of each module. Leachate collected within each module will be conveyed to a 2-foot deep, gravel filled sump. Liquids will be extracted from an HDPE riser pipe.

Landfill Gas Collection and Disposal System

A gas control system will be used to collect and dispose of landfill gas. Conceptually, the landfill gas system will consist of a system of horizontal and vertical gas wells, HDPE collection and header pipes and condensate sumps. Initially landfill gas will be disposed of using flares. Operation of the gas control system will not occur until there is a sufficient amount of methane to operate a flare disposal system.

A waste to energy system may be used to dispose of gas and generate electricity is such a system is determined to be feasible.

As a further protective measure, perforated gas extraction pipes will be incorporated in the Leachate Collection & Removal System layer to allow gas withdrawal from above the liner system, further reducing the potential of gas migration from the liner system.

Final Cover System

A final cover system will be constructed over the waste at the Jungo Disposal Site as part of the closure activities. The cover system is a prescriptive cover, in accordance with Nevada Administrative Code 444.6891, and consists of the following:
  • Minimum 2-foot thick vegetative soil layer
  • A geocomposite drainage layer
  • 60-mil HDPE geomembrane layer
  • One-foot thick foundation layer

Drainage Controls

Drainage controls will be implemented to control surface water run-on and run-off. These controls include:
  • Perimeter berm to prevent run-on
  • Retention basins, run-on and run-off control basin
  • Ditches and down-drains

Odor Control

Odor is controlled in a number of ways:
  • Daily cover of all compacted waste with a minimum of 6 inches of compacted soil or alternate daily cover
  • Keeping the active disposal area as narrow as possible while maintaining safe and efficient equipment operation
  • Immediate disposal and cover of highly putrescible wastes
In addition, since organic wastes such as food and green wastes are typically sorted out of the waste stream in Northern California, it is expected that the municipal solid waste will be drier, less putrescible material, thereby generating less odor.


Litter Prevention

Litter control measures will be implemented at the Jungo Disposal Site to prevent the scattering of papers and other lightweight debris. These control measures include:
  • Daily compaction and covering of waste
  • Perimeter fence around the facility
  • Temporary litter fence installed around active disposal area
  • Portable litter fences strategically placed at and around the active disposal area
  • Site attendants will be trained in proper litter control
  • Daily litter pick-up by site attendants


Monitoring

Environmental monitoring will be completed during landfill development and following closure. Monitoring includes groundwater monitoring, leachate monitoring and landfill gas monitoring.
