5.0 OPERATING PLAN

5.1 Miscellaneous

5.1.1 Facility Information The Apex Regional Landfill (landfill) is owned and operated by Republic DUMPco, Inc. (Republic). The

landfill is located 15 miles north of Las Vegas, Nevada at the intersection of Interstate 15 and Highway

93. The site contact information is provided below:

Mark Clinker General Manager Apex Regional Landfill 13550 North Highway 93 Las Vegas, Nevada 89165 Office: (702) 599-5091 Cell: (954) 232-9291 Emergency: (702) 599-5920 someone will answer 24-7.

From the Southern Nevada Health District offices at 625 Shadow Land, Las Vegas Nevada, the following

directions would direct you to the landfill:

1. Start at 625 SHADOW LN, LAS VEGAS going toward PINTO LN - go 0.2 miles. 2. Turn Right on ALTA DR - go 0.3 miles. 3. Turn Left on S MARTIN L KING BLVD - go 0.6 miles 4. Turn Right to take ramp onto I-515 S toward US-95 S - go 4.0 miles 5. Take exit onto Interstate 15 north go 15 miles 6. Take Highway 93 exit and turn right to enter landfill.

The site is made of the following parcels as defined by the Clark County Department of Comprehensive

Planning:

Parcel numbers: 103-13-000-003, 103-13-000-005, 103-13-000-006, 103-13-000-008, 103-24-000-004, 104-07-000-003, 104-07-000-005, 104-18-000-001, 104-18-000-002, 104-18-000-003, 104-19-000-001, 104-19-000-002, 104-19-000-003, and 104-20-000-001 (refer to Tab 8.8, Figure 8.8).

The landfill is currently permitted to dispose of solid waste by the Southern Nevada Board of Health. The

site Solid Waste Disposal Site Permit Numbers are LF001-G3X-01 for Class III disposal and LF002-G3X-

01 for Class I disposal. This plan proposes to combine the two permits into one permit for the Class I

solid waste disposal site and be operated under permit number LF002-G3X-01.

The Apex Regional Landfill operates 24-hours a day, 7-days a week. The Apex Landfill does not have an

interruption of operations that lasts four hours every six days, as "operating day" is defined in the Nevada

Administrative Code (NAC). A request for approval of current operating procedures was made by

Republic to the SNHD on November 1, 1999. The site is open 365 days per year. Current photographs of

the site are presented in Tab 9.




The proposed waste disposal footprint is approximately 1,722 acres, refer to Tab 14.

Tab 9 provides an aerial photo of the site for reference and street view photographs.

5.1.2 Managed Wastes NAC 444.684, Section 2(c) requires that a plan for operating a Class I landfill must provide for the

disposal of any special wastes specifically permitted by the solid waste management authority in the site's

permit. The existing Clark County Solid Waste permit for the Apex Regional Landfill (permit number

LF002-G3X-01) allows for the disposal of special waste. NAC 444.646 through 444.652 includes sewage

sludges, septic tank pumpings (including grease traps), medical wastes, waste tires, treated auto

shredder waste, and waste from construction and demolition, as special wastes. Untreated medical

waste must be handled in a method approved by the solid waste management authority pursuant to the

Nevada Administrative Code (NAC) 444.662 (6).

5.1.2.1 Special Wastes Permitted for Disposal in the Class I Landfill Radioactive waste, explosives, Resource Conservation Recovery Act (RCRA) hazardous waste, and

regulated polychlorinated biphenyl (PCB) wastes are not accepted at the Apex Industrial facility.

Materials accepted for disposal include, but are not limited to:

RCRA non-hazardous waste CERCLA non-hazardous waste Untreated medical waste Asbestos Fly Ash Crushed Drums Florescent Light Bulbs Pharmaceuticals Treated auto shredder waste (TASW) Stabilized Non-Hazardous Material Heavy Metal Contaminated Soil, Debris, Sand Blast Grit, and Bevell Exempt Mining

Waste

Crushed or Drained Filters Hydrocarbon Contaminated Materials: sludge, adsorbents, soil, tars, greases, rags, and

debris

Household Hazardous Waste Conditionally Exempt Small Quantity Generator Waste Meth contaminated waste (disposed of according to NRS 453.324)

Refer to Tabs 10.7 and 10.11 for special waste handling procedures.




5.1.2.2 Asbestos Waste Disposal The requirements of transporters of friable asbestos waste are provided in NAC 444.971. This regulation

stipulates the labeling and container requirements for asbestos waste. The transporters must notify and

obtain approval from the SNHD in conformance with NAC 444.972. The transporter must also notify the

landfill at least 24 hours in advance of delivery and contact the SNHD if any non-compliance issues occur.

The disposal will be located away from other waste disposal operations and hauling trucks will not be

allowed to travel over this area. Asbestos disposal areas will be recorded with the latitude, longitude and

elevation of the location of disposal within the waste mass. The asbestos waste will be disposed of in

accordance with NAC 444.976. The sign at the entrance to the landfill states that the landfill accepts

asbestos and asbestos containing waste.

No person will enter the asbestos disposal area during unloading and/or cover operations. If a person is

required to enter this area during these operations, they will be fitted with a respirator approved for

asbestos by the National Institute for Occupational Safety and Health Administration (NIOSH).

At closure, a written notice will be recorded with the property deed for the landfill with the Clark County

Recorders Office notifying future owners of the property that asbestos has been disposed of in the landfill

and that disruption or excavation is prohibited. The notice will present the locations of the disposed

asbestos by elevation, longitude and latitude. Tab 10.8 presents the Asbestos Acceptance and Disposal

Procedures for the landfill.

5.1.2.3 Waste Solidification Septic tank pumpings, grease traps, paint and other non-hazardous waste will be handled via the liquid

solidification facility located on site, refer to Tab 3.10 for Permit No. NEV93011. Haulers must be licensed

with the SNHD. Personnel at the scalehouse check that haulers bringing septic waste to the facility have

current permits with SNHD based on a list provided by the SNHD. The material is aerated and disced on

a regular basis. After reaching a suitable moisture content, the material is excavated from the drying

beds, stockpiled, and eventually mixed with native soils for continued absorption or for use as daily cover

material. The sources of septage and grease trappings delivered to the facility for disposal are the local

septage pumper/haulers and grease trap pumper/haulers located in the greater Las Vegas area. Other

wastes accepted for disposal will come from various enterprises within the greater Las Vegas area.

The Operations and Maintenance Manual for the Apex Bioremediation Facility and Liquid Solidification

Area is presented in Tab 10.14.

5.1.2.4 Treated Medical Waste Republic operates a medical waste collection program in the greater Las Vegas area. Collected wastes

are profiled and subsequently double bagged and placed in containment boxes for transportation to an

autoclave. Once treated, the waste is transported to a separate pit dug for disposal of this waste. The




only contact with the autoclaved waste is with the dozer pushing it into the pit and covering it. Once

deposited into the pit it is covered with 36 inches of cover material in accordance with NAC 444.646.

5.1.2.5 Third-party Treated Medical Waste Third-party treated medical waste is accepted from permitted facilities at transfer stations and disposed of

in the landfill.

5.1.2.6 Composting Currently the site does not compost woody and greenwaste materials delivered to the site. However, in

the future composting may become an activity that is undertaken at the landfill to divert waste and to

provide a beneficial use.

5.1.3 Prohibited Wastes The Apex Regional Landfill does not accept hazardous or PCB waste but is prepared to manage them

through on-site services provided by Environmental Technologies (ET) or other appropriately qualified

companies. ET is a full service hazardous and industrial waste management company capable of

handling hazardous wastes, contaminated site clean-ups, 24-hour emergency responses, underground

storage tanks, coordination of laboratory analyses, medical wastes, asbestos disposal, and household

hazardous waste collection and disposal. ET personnel are trained in hazardous waste programs.

Liquid wastes (as defined by Method 9095) are prohibited from disposal at the Apex Landfill except for

liquids in small containers similar in size to containers normally found in household waste may be

received at the working face as allowed in NAC 444.692 subsection 3. The handling and disposal of

controlled substances must comply with all the provisions of NRS Chapter 453 Control Substances.

All incoming loads are visually inspected at the scalehouse and additional random loads are further

inspected to ensure that prohibited wastes will not be disposed of at the site. Additionally, working face

spotters can identify suspect loads that are not identified at the scalehouse at the active landfill area.

Arriving loads are inspected for free liquids at the entrance gate by trained personnel prior to load

disposal at the working face. Loads that are suspect either due to testing or visual inspection are held

until the generator can be contacted and information obtained verifying that the load does not contain

hazardous or PCB waste. Loads without proper verification are rejected. The SNHD is notified of

rejected loads.

The scale house area is equipped with a nuclear radiation detector. All loads incoming to the site are

scanned. Refer to Tab 10.10, Radiation Monitoring Procedure, for a complete description of the program.

Information regarding prohibited wastes is presented in the following table.

5.1.3.1 Waste Tires Waste tires are managed in accordance with the Solid Waste Management Authority Tire Program.




5.1.3.2 Antifreeze Used antifreeze proper management procedures are specified in NAC 444.8801

(http://www.leg.state.nv.us/NAC/NAC-444.html#NAC444Sec8801) through 444.9071 and will be followed

by Republic for any antifreeze disposed of at the site.

5.1.3.3 Universal Waste Universal waste will be removed from the landfill within one year from when it is generated or received.

5.1.4 Waste Characterization Arriving third-party loads are inspected for prohibited waste at the entrance gate by trained personnel

prior to load disposal at the working face. Loads that are suspect either due to testing or visual inspection

are held until the generator can be contacted and information obtained verifying that the load does not

contain hazardous or PCB waste. Loads without proper verification are rejected and directions are given

to the hauler to a proper disposal facility. The SNHD is notified of rejected loads. A minimum 1% of all

third-party loads arriving at the site undergo this increased inspection procedure. The inspection includes

a visual inspection at the scalehouse and a more thorough inspection at the active face once the load is

dumped.

Waste is generally characterized as it is received at the site. A number of key codes are used to identify

waste types as they are weighed at the scalehouse prior to disposal, according to the sites Special

Waste Management Plan. This system identifies the type and quantity of waste accepted on a continuous

basis to provide Republic with a summary of the type and quantity of materials being disposed of within

the site.

If the onsite generated leachate exhibits hazardous characteristics, SNHD must be notified and the

leachate must be handled as a hazardous waste and shall not be recycled back into the landfill. Leachate

is sampled and analyzed quarterly.

Septic waste haulers are inspected for valid permits at the scalehouse. Unpermitted haulers are turned

away and reported to the South of the health district.

5.1.4.1 Recordkeeping of Inspections Incoming waste is inspected and rejected loads are documented on a rejected load form which includes:

Date and time waste loads were received and inspected Source or generator of the wastes Vehicle and driver identification Observations made by the inspector Description of loads rejected and rationale for rejection




5.1.4.2 Training of Facility Personnel Facility personnel are trained in methods to identify containers and labels of typical hazardous and PCB

containing wastes. Training for hazardous material screening procedures addresses hazardous waste

handling, safety precautions, and recordkeeping requirements. Documentation of personnel training is

included with the facility operating record on site.

Internal procedures established for effectively screening wastes include:

Random inspection of incoming loads Records of inspections Training of facility personnel Handling procedures for hazardous or PCB waste Notification

Training of site personnel to identify prohibited wastes includes the following:

GOALS OF WASTE SCREENING 1. Protect the environment 2. Protect Employees from exposure to hazardous waste 3. Protect the company from accepting hazardous waste 4.

5.1.5.1 Hazardous Waste If regulated quantities of hazardous or PCB wastes are identified on incoming haul vehicles, Republic will

refuse to accept the load and notify SNHD and ET, the onsite company responsible for managing special

wastes at the landfill. ET will manage subsequent activities related to the waste load, including

transportation, storage, and containment. If these wastes are found at the working face of the lift,

Republic will see that the waste is managed in accordance with applicable federal and state regulations.

Wastes that are determined to be hazardous may be stored by Republic for up to 90 days per 40 CFR

262.34. To satisfy this section of federal regulations, Republic will perform the following:

Place waste in tanks, 55-gallon containers, or other appropriate containers to prevent leakage of hazardous waste during both normal transport conditions and potentially dangerous situations

Clearly label the container of waste with the date of packaging Clearly mark the container with the words, "Hazardous Waste" Mark the name and telephone number of the emergency coordinator (i.e., operations

manager or safety manager) on the container

If the waste is transported off site, a provisional or one-time U.S. Environmental Protection Agency (EPA)

identification number is obtained if one does not already exist. The waste will be packaged per applicable

Department of Transportation regulations, and the container will be properly transported and manifested

to its point of destination.

In the event PCB wastes are identified on-site, Republic will store and dispose of the waste per 40 CFR

Part 761. Republic will:

Obtain an EPA PCB identification number, if one does not already exist Properly store the PCB waste until transport Properly mark the containers with the words, "Caution: Contains PCBs" Manifest the container for shipment to a permitted facility for disposal

Republic will use the Uniform Hazardous Waste Manifest (EPA Form 8700-22) to document the transport

of hazardous waste from the facility to its destination. Republic will notify NDEP if it does receive a

signed and dated copy of the manifest from the destination within 60 days if the facility is a small quantity

generator (SQG) or within 45 days if the facility is an large quantity generator (LQG). The manifest




received from the destination must be kept for at least three years from the date on which the hazardous

waste was accepted by the initial transporter.

5.1.5.2 Notification If suspected hazardous materials or PCB wastes are discovered within the municipal operations, Republic

will notify the SNHD. A record will be prepared for submittal to SNHD that will identify the date and time

of discovery of the material, the identification of the material (if possible, without analytical testing), the

hauler that delivered the material to the facility, the quantity of the material, and the proposed actions by

Republic to remove the material from the area. The record of notification will be entered into the

operating record maintained at the facility.

5.2 Air Control Water for dust control and compaction of cover material outside the limits of waste is provided by on-site

wells. Liquid for dust control within the limits of waste is provided from leachate and landfill gas (LFG)

condensate. Leachate and LFG condensate are only applied over lined areas of the landfill. Approval of

leachate application for dust control and the overall Title V Part 70 Operating Permit are provided in Tab

3.6.

The landfill currently monitors for hydrogen sulfide emissions at the site. The monitoring program includes

measuring H2S on a continuous 24 hour per day, 7 days per week basis. The monitoring equipment is

located on the roof of the maintenance building in the recording data is located on the second floor. Refer

to Tab 10.16 for the Quality Assurance Project Plan For Continuous H2S Monitoring. A request to stop the

H2S monitoring program has been submitted to the Air Quality Management District.

5.3 Emergency Control

5.3.1 Fire Control The Landfill Emergency Procedure Handbook is used as a guideline for responding to fires. Site

personnel are trained using this handbook.

In the event of a structural fire, the closest fire department at 4040 Losee Road (10 miles south of the

Apex Regional Landfill) will be contacted. Fire prevention and suppression practices are detailed in the

Landfill Emergency Procedure Handbook created through the Republic Health and Safety Program.

The Apex Regional Landfill procedures have been reviewed by the Clark County Fire Department. This

manual is available for review on site.




5.3.2 Pollution Control

5.3.2.1 Hazardous Waste Republic follows proper management procedures specified in 40 CFR Part 262, which include the

following requirements:

1. Republic must total or count the weight of all hazardous wastes generated in a calendar month in order to determine if they will be regulated as a Large Quantity Generator (LGQ), Small Quantity Generator (SQG), or Conditionally Exempt Small Quantity Generator for that particular month.

2. SQGs must properly accumulate hazardous waste in containers or tanks. LQGs must properly accumulate hazardous waste in containers, tanks, drip pads, or containment buildings.

3. Containers and tanks will be marked with the words Hazardous Waste.

4. Containers will be kept closed and marked with the date on which accumulation began.

5.3.2.2 Ozone Depleting Substances Republic is responsible for ensuring that ozone-depleting substances [generally chlorofluorocarbons

(CFCs) and hydrochlorofluorocarbons (HCFCs) and their blends used as refrigerants are recovered from

air-conditioning and refrigeration equipment [e.g., motor vehicle air conditioners (MVACs), household

refrigerators and freezers, and room air conditioners) before the final disposal of the equipment. Chill-Tek

located at 4621 N. Lamb Blvd., Las Vegas, Nevada or other approved vendors perform these services at

the site.

Equipment used to remove ozone depleting substances must be registered or certified with the SNHD.

Personnel using the equipment are trained for proper use, but there is no certification required.

The US Environmental Protection Agency has issued the Mandatory Reporting of Greenhouse Gases Rule. The rule requires reporting of greenhouse gas emissions from large sources and suppliers in the United States. The Greenhouse Gas Monitoring Plan, see Tab 10.15, for the Apex Regional Landfill which includes the following:Positions of Responsibility identification of positions of responsibility for data collection

Process and Methods explanation of the processes and methods used for data collection

Procedures and Methods description the procedures and methods used for quality assurance along with maintenance and repair of instrumentation used to report greenhouse gas emissions

5.3.2.3 Universal Waste Republic follows the proper management procedures specified in 40 CFR Part 273.

5.3.2.4 Used Antifreeze Republic follows the proper management procedures specified in NAC 444.8801 through 444.9071.




5.3.2.5 Used Oil Republic follows the proper management procedures specified in 40 CFR Part 279 that include the

following requirements:

1. Used oil is stored in tanks and containers with clearly marked containers and tanks with the words Used Oil. The containers and tanks are kept in good condition and free of leaks. Any spill or leak from a container is immediately addressed to avoid a release to the environment and the situation causing the leak or spill addressed.

2. All used oil containers and tanks are equipped with secondary containment to prevent oil from reaching the environment in the event of a spill or leak. Secondary containment consists of oil-impervious dikes, berms, or retaining walls to contain releases, as well as an oil-impervious floor to prevent migration.

Used oil collected in the HHW program is used on site as fuel for furnaces that heat the maintenance area

during the winter or is solidified in the solidificationl treatment facility (STF) and disposed of in the landfill.

5.3.3 Other Procedures Site personnel are equipped with radios to allow for direct communication between management and

operating personnel. These radios not only provide an avenue for communication during normal operating

conditions but also provide communication assistance in case of emergency.

In the case of a fire the following procedure is taken:

The site is not located within a flood zone and therefore no procedures for this type of situation have been

developed.

Environmental pollution at the site is predominantly controlled through the implementation of best

management practices. Because the site does not discharge storm water, no regulatory mandated plans

are necessary for storm water pollution control. However, Republic maintains internal policies to clean up

spills and other potential pollution issues that may arise. Republic also maintains a log of pollution




5.4 Employees Sufficient personnel are employed at the Apex Regional Landfill to ensure efficient and coordinated daily

operations 24 hours a day, 7 days a week. An Operations Manager is available on a 24-hour per day

basis. The general responsibilities of the employees at the site are as follows:

Management - Overall operations of the facility, maintaining compliance with the Plan of Operations, and overseeing equipment and personnel

Supervisor - Scheduling and supervising daily operations staff and equipment maintenance

Gate Keepers - Weighing and measuring waste and screening loads for improper wastes at the scalehouse

Spotters - Screening loads for improper wastes at the active disposal area and maintaining control of access

Equipment Operators - Safe and efficient operations of equipment and basic fire suppression training

Mechanics Routine maintenance for equipment and keeping equipment operational Utility Crews Collect windblown litter and maintain clean landfill area

Personnel employed at the Apex Regional Landfill are trained in proper landfill and safety procedures.

Training is administered and documented by Republic staff. An average of 72 employees are on site

during a 24 hour period.

5.5 Equipment Please refer to Tab 10.2 for an equipment list of all equipment used for waste management activities at

the facility.

Equipment is used for loading and covering solid waste on the face of the lift, transporting cover material,

compacting and covering, grading surfaces of the landfill and roads, maintaining surface drainage and

haul roads, providing air quality controls, and providing fire suppression support. The equipment and

personnel available at the Apex Regional Landfill are sufficient to compact and grade wastes, apply

appropriate cover, and maintain drainage and road structures.

The operator maintains a readily available inventory of heavy equipment that may be called into active

service in case of a breakdown of operating equipment at the working face. In addition, an on-site

maintenance repair shop operated at the facility enables expedient deployment of staff and equipment to

address equipment repairs. It is anticipated that with an on-site inventory of continually upgraded

equipment and with immediate repair capabilities, equipment downtime will be of minimal impact to

ongoing facility operations. Should there be an emergency or a temporary need for additional equipment,

rental equipment can be attained.




The equipment inventory will continually fluctuate to accommodate the operational needs of the Apex

Regional Landfill. The precise number and type of equipment will also change as equipment is upgraded

or replaced over time.

5.5.1 Equipment List Refer to equipment list in Tab 10.2.

5.5.2 Equipment Maintenance Republic employs a staff of trained mechanics and support crew to perform daily maintenance on

equipment. They perform routine inspections that include examinations of brakes, safety lights, oils and

hydraulic fluids, tires, and all on-board safety equipment. Services are performed on equipment at regular

intervals. Maintenance records are kept on file at the facility. The equipment availability is greater than

the fleet utilization, enabling regularly scheduled service and maintenance of the equipment, as well as

back-up if equipment is down for repair.

5.6 Facility Access The Apex Regional Landfill is an isolated site. This isolation assists in keeping unauthorized vehicular

traffic away from the landfill. There is only one entrance to the site and it is controlled by personnel at the

scale house. Visitors must check in at the scale house prior to entering the site. The natural topographic

barriers around the site prevent access to the landfill other than through the front gate. An attendant is on

duty 24 hours a day at the scale house to control access to the facility.

Republic strictly prohibits scavenging. Controlled site access and the site operator prohibit scavenging at

the working face. The working face is illuminated during night time operations, and employees are aware

of the strict policy against scavenging.

5.7 Facility Capacities Refer to Tab 4.7 for the discussion on facility capacities and Tab 13 for plans associated with the capacity

to evaluations for the site.

5.8 Litter Control Generation of windblown debris at the active working face of the lift is a common occurrence at municipal

solid waste landfills. Windblown debris commonly consists of lightweight waste materials blown from the

active working area. It may be generated by the physical unloading of waste from haul vehicles and

containers. When wind speeds become excessive, debris may be blown from the active area and carried

to other parts of the facility. As wind speeds increase, the quantity of windblown debris in the area may

correspondingly increase.




Site personnel monitor climatological data to identify upcoming days where high winds are expected.

Prior to high winds, portable litter fences are maneuvered around the active face of landfill downwind to

minimize litter blowing to other portions of the site. Septic and sludge wastes are deposited directly to the

processing area away from site personnel and the public. These wastes are deposited in such a manner

that the wind blows any waste constituents downstream from personal nearby. High wind conditions are

not believed to expose the public or site personnel to increased exposure. Refer to Tab 10.12, Litter

Control Plan for additional information.

Climatological data from the site indicates the wind direction at the Apex Regional Landfill is commonly

from the northeast and from the southwest. Procedures in place for controlling litter include:

Compaction of the active disposal area as soon as practicable on a 24-hour basis Spraying water on haul roads and areas adjacent to the working face in order to control

lightweight debris

Using litter control fences and collecting windblown materials from immediate land areas on an as needed basis and properly disposed of at the working face

Collecting litter from perimeter fencing at least monthly by the facility staff Patrolling access and perimeter roads on a daily basis. Windblown litter will be picked up

on an as-needed basis

Litter control will be performed by Republic personnel. If litter is blown from the landfill to surrounding properties, either landfill staff or hired day laborers will collect litter on a regularly scheduled basis

5.9 Odor Control Republic will operate the landfill in a manner that will minimize creation of odors, unsightliness, or other

nuisances. Odorous materials disposed of at the landfill are immediately covered with other refuse or soil

to suppress the odors. If materials are accepted that are known to be odorous, a pit is dug within the

landfill near the active disposal area and the material is immediately covered with soil or additional waste.

The landfill refuse undergoes anaerobic decomposition. As such, gases, predominantly methane, are

produced that may cause odors. A landfill gas (LFG) collection system is in place to convey LFG to a

control system, currently a flare and third party energy recovery system. The flare and/or energy

producing engines combust the LFG at a high temperature reducing the greenhouse gas effects of the

LFG.

To determine the effectiveness of the LFG collection system, the surface of the landfill undergoes surface

emission monitoring quarterly to detect LFG leaking from the surface of the landfill. In areas where LFG is

detected, additional soil is placed to deter the escape of the LFG to the atmosphere and the LFG

collection wells in the immediate area are reviewed to determine if the vacuum can be increased to collect

additional LFG from the area to relieve the pressure that is forcing the LFG to escape.




Refer to Tab 4, Section 4.14.2 for further description of the LFG control system and Tab 15 for LFG

Operations and Control Plans.

5.10 Public Areas There are no dedicated public areas at the site. The public is granted the same access as commercial

haulers and must follow the same traffic control patterns. At the active face, the public is guided to a

location away from the commercial haulers to allow for the public to discard their loads in a safer

environment, dislocated from heavy equipment. A traffic spotter is available during normal business hours

Monday through Friday and as needed when public is present to direct traffic at the active face.

5.11 Traffic Control Refer to Tab 4, Section 4.11 for traffic control features.

5.12 Vector Control The Landfill is operated in a manner that controls populations of burrowing animals, restricts trespassing

by native desert animal populations, and minimizes the breeding opportunities for insects. The continuous

activity at the working face virtually eliminates the presence of rodents and other small animals. Small

animals are scared away by the continuous transfer truck traffic and the compactors working the open

face, and they have no opportunity to pick through the refuse undisturbed.

Desert mammals common to the Great Basin region, such as coyotes, mountain lions, wild horses and

burros, will be chased from the property whenever observed by Apex facility personnel. The continuous

activity at the landfill is typically enough to keep desert animals away as animals have not been an

invasive problem to date. The facility is enclosed by a desert tortoise fence along the entire perimeter,

except for areas of terrain steep enough to prohibit access. If animal invasions become a safety or health

concern to Republic, notification will be filed with the proper Authority and placed in the operating record.

Effective management programs for the larger desert mammals can then be agreed to by the proper

Authority and Republic and may consist of trapping, roundups, or herd culling as deemed appropriate.

Bulky wastes that may provide for the harborage of rodents will not be used for final surface side slopes.

Bulky waste material will be properly covered within the refuse in the municipal waste area so that rodents

cannot take refuge in the small spaces.

The grading of the landfill is predominantly carried out in a fashion that precludes ponding of water on the

landfill to prohibit the potential for mosquitoes.

Vector control within the bioremediation facility is carried out by pumping the water from pond to pond so

it does not become stagnant.




Vector control within the liquid solidification area is carried out by covering and mixing liquid wastes in a

timely fashion.

5.13 Waste Measurement Refer to Tab 4, Section 4.13 for a discussion on waste measurement.

5.14 Waste Processing

5.14.1 Landfill Covers Apex Regional Landfill operates 24 hours-a-day, 7 days-a-week. Currently, the site continuously covers

discrete areas of waste with additional waste or soil within 24 hours. Waste is placed in lifts over an active

area of the landfill, and as the tipping floor (i.e. area receiving waste) moves laterally, cover soil is placed

over the lift. The soil cover creates a stable floor for vehicular traffic and tipping operations. As an area is

filled with a completed lift, a new lift is begun on top of the old lift, and soil barriers may be removed from

the previous floor. Areas that are not actively receiving waste remain covered with soil. Continuous waste

placement satisfies the requirements for control of disease vectors, fires, odors, blowing litter,

scavenging, and presents no danger to public health or the environment. Areas that will not receive waste

for more than 90 days receive an intermediate cover of 12 inches of soil. The operations described above

have been previously approved by the SNHD. Based on inspections by the SNHD, the continuous waste

placement operations for control of vectors will be assessed. If additional operating criteria or revisions to

the existing operations are identified to increase the control of vectors, Republic will work with SNHD to

implement additional controls or revise operations as necessary.

Republic is requesting that interim refuse slopes used for the unloading of waste be constructed with a

minimum slope of one percent. The requested one percent slopes facilitate the safe operation of tippers

(hydraulic systems that empty transfer trucks by raising the front end of the transfer trailer to an

approximate 45 degree angle with the ground surface). Slopes steeper than one percent can create

dangerous situation where the tippers, when extended, can become unstable. Utilizing a one percent

slope reduces this potential significantly while still maintaining surface water runoff control. All final slopes

will have a minimum grade of three percent.

Special wastes accepted that or not further processed onsite are buried near the active face and

immediately covered with a suitable cover material at least 36 inches in depth.

Due to the desert climate at the site, vegetation will not be immediately established on final slopes or

slopes not covered within a two year period. Natural vegetation will establish over time. Erosion control of

the covered slopes is maintained with the use of a rock soil matrix that armors the slope against erosion.

This type of cover system is currently used for covering interim slopes and will be used for final cover.




Final slopes of the landfill are established with refuse materials that exclude bulky wastes. The use of

bulky waste near the final surface of a landfill may allow for harborage of rodents and/or potential for large

amounts of differential settlement near the final cover system.

Final cover is described in Tab 4, Section 4.15.1.

5.14.2 Landfill Gas Control The Class I area is lined with a geomembrane and has a landfill gas collection and control system

(GCCS) consisting of horizontal collectors, vertical wells, a flare station and an energy recovery facility.

This system of containment and collection controls explosive gases. To date, perimeter monitoring results

have not detected any landfill gas.

Methane monitoring devices are located in the scalehouse, operations building, breakroom trailer, and

H2S facility, refer to Tab 4 Section 4.15.2. According to EPA's RCRA regulations, owners and operators of

landfills subject to monitoring requirements must ensure that the concentration of methane gas does not

exceed 25% of the LEL for methane (1.25% by volume) in indoor air samples collected in the facilities'

structures. In the unlikely event that 25 percent of the lower explosive limit is exceeded in structures,

Republic will immediately take action to ensure protection of human health. The following contingency

plan will be followed by facility operating personnel.

Within 7 days after detection, Republic will fill out a report, submit it into the operating record, and notify the SNHD as the Solid Waste Management Authority. The operating record will note the date on which the limit was exceeded, the detected limit at the time of exceedance, and additional steps taken.

Within 60 days of exceedance, Republic will develop a landfill contingency plan or remediation plan, place a copy of the plan in the facility operating record, and notify the Authority that the plan was carried out.

All smoking material and fires of any kind, including electric arc welding, metal grinding, etc., will be discontinued or extinguished immediately.

The Apex Facility will be inspected by the operations manager and a safety specialist to identify any cracks in the cover that may be emitting landfill gases. The operations manager will be fitted with a personal respirator with cartridges designed to filter hydrocarbon compounds from the air while performing this task. The safety specialist will have access to communication and safety equipment, including two emergency air supply devices or systems.

Any identified cracks in the landfill cover will be repaired by filling with soil as soon as practicable to reduce the possibility of gas emission.

Methane monitoring will be conducted to determine the effectiveness of the cover repair. Adjustments will be made in the gas collection system to improve efficiency.

Increased frequency of monitoring may be required if lower explosive limits are continually detected through either subsurface soil or facility monitoring. Gas monitoring will be conducted at a frequency that is sufficient to detect gas migration based on subsurface conditions and changing landfill conditions.




A permanent methane monitor is installed in the maintenance and bioremediation buildings.

A record will be maintained of the progress of the plan and reported to the SNHD.

The condensate from the landfill gas is being discharged into the holding tanks and/or evaporation ponds.

The effluent being discharged to the holding tanks and evaporation ponds is monitored quarterly to

determine if it exhibits hazardous waste characteristics. The Operations and Maintenance Manual for On-

site Holding Tanks is presented in Tap 16.3

The site also operates a landfill gas (LFG) hydrogen sulfide (H2S) treatment facility. This facility is an

enclosed building approximately 8,000 square feet equipped with H2S gas removal equipment that is

used to pretreat the LFG prior to combustion in turbines used to create electricity. The energy plant,

located on 1.5 acres in the southwestern corner of the site, uses the treated LFG to fuel two Solar

Centaur 60 combustion turbines manufactured by Solar Turbines, a subsidiary of Caterpillar Inc. LFG is

drawn from vertical and horizontal wells up to 300 feet deep that tie into a header system that conveys the

LFG to the H2S removal system to treat sulfur content. Next, gas is filtered for moisture and particulates

then is compressed and injected into the 5.5-megawatt air-cooled turbines that generate electricity.

Emissions are treated by a selective catalytic reduction process that removes harmful nitrogen oxides

from the exhaust plume. Elemental sulphur extracted is placed 3 cy roll off and landfilled on site.

Analytical data for the solution used to extract the sulphur and analytical data for the extracted sulphur

cake is included in Tab 10.13.

5.14.3 Other Procedures The working face of the municipal operation will be kept narrow to be consistent with safe and efficient

operation of equipment, 155,250 square feet is the approved open face area that the landfill is restricted

to. This approved area allows for safe operations and the ability to segregate the public from the

commercial haulers. There are currently two anticipated events where the open face will be larger than

normally expected during any observation. Those two events are:

1. When the landfill active area is performing a tum-around, and

2. When a new cell is opening at a different location.

In a "turnaround," the active face of operations must build a new lift and proceed back from the direction it

just came from, effectively turning around. In a new cell, the waste must be placed into a concentrated

area of approximate 2 acres, piled upon previously placed waste to build an elevated lift upon which

equipment will be placed for operations.

Waste placement operations are discussed in Tab 4, Section 4.14.




5.14.3.1 Sludge Acceptance Characterization of sewage sludge received from local municipalities will be performed by the waste water

treatment plant shipping sludges to the site for disposal. Paint filter tests will be performed on the sludges

at the waste water treatment plant to determine the presence of free liquids in a representative sample.

The number of paint filter tests performed will be dependent upon the requirements of the waste water

treatment plant. If the number of tests is not sufficient, the testing may be negotiated as a term of

disposal.

All analytical testing will be performed by a State of Nevada certified laboratory. All sampling by the waste

water treatment facilities will follow the guidelines set for in US EPA publication SW-846, Test Methods for

Evaluating Solid Waste, Physical/Chemical Methods. Previous sludge monitoring reports submitted to the

Nevada Division of Environmental Protection (NDEP) will also be attained and submitted to the SNHD if

applicable prior to shipment to the site for disposal. The volume of sludge disposed and the date received

will be recorded and maintained in the site operating records, refer to Tab 10.9.

5.15 Water Protection

5.15.1 Industrial Waste Drainage Control The industrial waste area is graded to drain. All storm water that falls onto this area drains to the

perimeter of the site where it ultimately discharges offsite or infiltrates into natural ground.

5.15.2 Leachate Control A copy of Leachate Management Plan is provided Tab 16.4.

5.15.2.1 Class I Leachate Control Leachate is controlled from discharging to the environment through the use of a liner system. The liner

system is comprised of the following from bottom to top:

Prepared subgrade 6-inch thick subgrade preparation layer (k0.2 cm/sec) 12-inch thick layer of random fill

The base grades of the landfill slope to a series of leachate collection trenches that are equipped with a

perforated 6-inch diameter HDPE pipe that is surrounded by gravel fill (crushed stone with a minimum

permeability of 0.2 cm/sec). These trenches convey leachate to dedicated sump area where it can be

removed from the landfill.




A construction quality assurance (CQA) program is followed to ensure the base liner system is

constructed correctly and that defects are minimized in the geomembrane. The CQA plan utilized for the

site is entitled Quality Assurance Manual for Construction of Lining and Leachate Collection Systems,

Apex Municipal Waste Landfill, May 2006. This document is on file with the SNHD. The purpose of this

manual is to describe the quality assurance procedures to be used during construction of liner and

leachate collection components at Apex Landfill, Clark County, Nevada. The primary goals of the quality

assurance program are to:

Determine if proper construction techniques, materials, and procedures are used Determine if the intent of the construction documents and project design reports are met Identify construction problems and provide a mechanism for resolution

Upon completion of construction, information generated through the quality assurance program will be

used to prepare a project construction report.

5.15.2.2 Class III Leachate Control The current industrial disposal area was constructed with a double composite liner system to provide

enhanced protection of a release to the environment. The liner system consists of the following

components from bottom to top of:

Prepared subgrade 6-inch thick subgrade preparation layer (k

Selected Test Method for all Inorganic Elements 2. Selected Test Method for all Organic Elements

Groundwater sampling and reporting occurs semiannually. Reports are submitted to the SNHD

semiannually. There is one upgradient well, MW-6, and three downgradient wells, MW-2, MW-5 and MW-

7 that are sampled. The Operating Plan for the Apex Landfill provides that, absent any indication of

groundwater contamination, monitoring data for each sampling event are to be evaluated using the

preceding monitoring data as additional background or baseline data. If the prediction limit and control




chart analyses again give no indication of groundwater contamination, the data from the most recent

sampling event are to be considered as background or baseline data. Statistical analysis of analytical

results are performed utilizing DUMPSTAT statistical software according to State of Nevada and Clark

County criteria and NAC Section 444.7485. If groundwater contamination is detected in the future,

requirements presented in NAC Sections 444.7489 to 444.7499 will be followed.

Analyses of groundwater monitoring data from July 1997 through May 2012 using intra-well (control

charts), upgradient versus downgradient (prediction limits), and time series (trend analysis) give no

indication of groundwater contamination at the Apex Landfill.

5.15.4.2 QA/QC

5.15.4.2.1 Field QA/QC Use of the field quality assurance procedures will aid in the characterization and interpretation of the

water quality data. The procedures will serve as documentation for data variability and will assist in the

detection of false positive or negative results in the analyses. Quality control field checks will consist of

the use of the following:

1. Trip blanks. These will consist of clean water taken to the field in containers that have been cleaned and sealed in a manner consistent with the procedures to be used in the field. They will be taken to the site, handled, and stored according to sampling protocol, and they will be returned unopened.

2. Field blanks. The field blanks will consist of clean water taken to the site, and they will be collected in the appropriate sample containers at the field location and handled, stored, and transported with the monitoring well samples. Field blanks will not be identified as such and will be submitted to the laboratory and analyzed as if they were part of the actual sample group.

3. Field duplicates. Duplicate field samples will be taken from the same well location and sample interval as the original sample. One duplicate sample will be taken per sampling event. They will be sequential water samples collected in separate containers. Field duplicates will not be identified as quality control samples and will be analyzed for the same parameters as identified in the sample program.

5.15.4.2.2 Laboratory QA/QC Internal quality control checks are standard procedure for analytical laboratories. The QA/QC procedures

commonly include the use of blanks, duplicates, and spikes, as well as additional checks if apparent

anomalous values are returned during analysis. The laboratory selected to perform the sample analyses

will provide Republic with documentation of its internal QA/QC procedures, and the laboratory will include

methods for routine calibration of instruments, statistical analyses of precision and accuracy data, sample

and data handling, control of sample integrity during analytical procedures, and quality review of analysis

work sheets. Only EPA-approved methods will be used for laboratory testing.




5.15.4.2.3 Procedures in Case of Leachate Migration If there is a statistically significant increase over background for one or more of the constituents listed in

40 CFR Part 258 Appendix I or the list of alternative parameters established pursuant to NAC 444.7487,

at any monitoring well at the boundary specified by NAC 444.7483, the owner or operator shall:

(a) Within 14 days after making this determination, place a notice in the records of the disposal

site indicating which constituents have shown statistically significant increases and notify the solid

waste management authority that this notice was placed in the operating records; and

(b) Except as otherwise provided in subsection 2, establish a program for assessment monitoring

pursuant to NAC 444.749 and 444.7491 within 90 days after making the determination.

The owner or operator may demonstrate that a source other than a municipal solid waste landfill unit

caused the contamination or that the statistically significant increase resulted from an error in sampling,

analysis or statistical evaluation or from a natural variation in the quality of groundwater. A report

documenting this demonstration must be certified by a qualified groundwater scientist, approved by the

solid waste management authority and placed in the operating records of the disposal site. If a successful

demonstration is made and approved, the owner or operator may continue monitoring constituents as

specified in this section and NAC 444.7487 and 444.7488. If, after 90 days, a successful demonstration is

not made, the owner or operator shall initiate a program for assessment monitoring pursuant to NAC

444.749 and 444.7491.

1. If a statistically significant increase over background has been detected for one or more of the

constituents listed in Appendix I or the list of alternative parameters established pursuant to NAC

444.7487, an owner or operator shall establish a program for assessment monitoring.

2. Except as otherwise provided in subsection 3, within 90 days after initiating a program for

assessment monitoring, and annually thereafter, the owner or operator shall sample and analyze the

groundwater for all constituents identified in 40 CFR Part 258 Appendix II. At least one sample from each

downgradient well must be collected and analyzed during each sampling. For any constituent detected in

the downgradient wells as a result of this analysis, at least four independent samples from each

background and downgradient well must be collected and analyzed to establish background for the

constituents. The solid waste management authority may specify an appropriate subset of wells to be

sampled and analyzed for constituents listed in Appendix II during assessment monitoring. The solid

waste management authority may delete any of the parameters for monitoring constituents listed in

Appendix II for a municipal solid waste landfill unit if it is shown that the deleted constituents are not

reasonably expected to be in or derived from the waste contained in the unit.




3. The solid waste management authority may specify an appropriate alternative schedule for

monitoring all constituents listed in Appendix II. The alternative schedule must be based on the:

a. Lithology of the aquifer and unsaturated zone

b. Hydraulic conductivity of the aquifer and unsaturated zone

c. Rate of flow of groundwater

d. Minimum distance between the upgradient edge of the municipal solid waste landfill unit and

downgradient monitoring well screen

e. Resource value of the aquifer

f. Nature, fate and transportation of any constituents detected in accordance with this section

4. After obtaining the results from the initial or subsequent samplings pursuant to subsection 2 or 3, the owner or operator shall:

a. Within 14 days, place a notice in the operating records of the disposal site identifying the

constituents listed in Appendix II which have been detected and submit the sampling results to

the solid waste management authority.

b. Within 90 days, and on at least a semiannual basis thereafter:

1) Resample all wells specified by NAC 444.7483

2) Conduct analyses for all constituents listed in Appendix I or the list of alternative

parameters established pursuant to NAC 444.7487, and for those constituents in

Appendix II which are detected as a result of sampling pursuant to subsection 2 or 3

3) Record their concentrations in the operating records for the disposal site

At least one sample from each background and downgradient well must be collected and analyzed during

the samplings. The solid waste management authority may specify an alternative schedule for monitoring

the constituents referred to in this section. The alternative schedule for constituents listed in Appendix I or

the list of alternative parameters established pursuant to NAC 444.7487 may not require monitoring not

less than annually. The alternative schedule must be based on the factors specified in subsection 3.

c. Establish background concentrations for any constituents detected pursuant to paragraph (b) or

subsection 2 or 3.




5.15.4.2.4 Liner QA/QC All liner systems constructed at the landfill follow strict quality assurance/quality control guidelines. These

guidelines are presented in a Quality Assurance Manual to the SNHD prior to construction for approval. A

copy of the most recent Quality Assurance Manual for Construction of Lining and Leachate Collection

Systems for the Apex Landfill is presented in Tab 16.5.
