Operation and Maintenance Manual System Name: Red Rock Canyon Visitor Center BLM PWS PWS ID Number: NV 0005011 Number of connections: 2 Population served: 3,200

System Description The Red Rock Canyon Visitor Center BLM (RRCVC) Public Water System (PWS) is located on State Route 159 (SR-159) approximately 5.5 miles west of the intersection of SR-159 and Clark County Road 215 in Las Vegas, Nevada. The system consists of one pressure zone served by one well. The purpose of the water system is to provide drinking water for employees and visitors of Red Rock Canyon. The system is classified as a Non- Transient Non-Community Water System.

RRCVC Total Connections = 2 Recreational or Commercial Approximate Population Served (BSDW database) = 3,200

The RRCVC Well is located at the following GPS coordinates: Latitude 36°7’49.51”, Longitude -115°25’39.79”. This well was drilled in December 3, 2016 by Great Basin Drilling (Address: 1220 Manse Road, Pahrump, NV 89048; Contractor’s Lic. No. 47333;

Driller’s Lic. No. 2485). The well was drilled to a depth of 600 feet, below ground surface (ft, bgs) and is cased to 600 ft, bgs. The casing is perforated from 140 to 200 ft, bgs. The static water level at the time of well completion was 442 ft, bgs. At this time the well yielded 11 gallons per minute. The well pumps water into a 10,000-gallon underground storage tank located adjacent to the wellhead. The pump is turned on automatically or manually when the water level in the underground water storage tank reaches 60 inches above the bottom of the tank, and turns off when the water level in the tank reaches 78 inches above the bottom of the tank. The pump can also be manually operated using the pump toggle switch located inside the pump building (see the attached Operation and Maintenance Manual: Red Rock Canyon Visitor’s Center Water Treatment & Distribution).

Drinking water supply wells are categorized according to the use pattern. A Permanent well is a well that is routinely utilized throughout the year, including wells utilized daily or as back-up/standby sources for peak demands or operational flexibility. An Emergency well is one that is not preferred for usage due to undesirable conditions (e.g. water quality, well construction) but could be utilized if a failure of the primary source occurs. Seasonal wells are utilized only during certain periods of the year. Water quality can undergo significant changes as a well goes unused, so Emergency and Seasonal wells require site-specific start-up procedures to ensure that water with degraded quality is not pumped into the system. In addition, the NDEP-BSDW must be notified of Emergency or Standby wells in the system so that appropriate analytical schedules can be provided.

The RRCVC well is used on a permanent basis.

Routine disinfection/treatment is practiced. The chlorinator meters a sodium hypochlorite solution directly into the well water supply line inside the Pump Building. It is currently calibrated to provide a mixture of 1.5 parts per million. The chlorinator requires periodic monitoring to ensure the supply of disinfectant does not run out. The well is equipped with a water meter located on the outgoing line to the pump building. A vacuum breaker has been installed on the single hose bib inside the pump building.

Spare Parts Spare parts ARE NOT kept on-site. The system relies on the RRCVC management and maintenance personnel for continuous operation of the well and on nearby supply houses including well professional Great Basin Drilling located in Pahrump, NV ((775) 727-4462).

If the water system has electrical problems RRCVC will contact local electrical contractors. In accordance with the Federal Acquisition Regulations, RRCVC may competitively bid service and repair contracts for the RRCVC PWS as required.

Suppliers are listed in the contacts section under the Emergency Response Plan.

RRCVC utilizes US Blue Book to keep spare parts on-site.

Disinfection Routine, continuous disinfection is practiced by the RRCVC PWS using Sodium Hypochlorite. The Material Safety Data Sheet for Sodium Hypochlorite can be found in the Appendices. Safety goggles are worn every time the Distribution Operator is working with Sodium Hypochlorite. Eye wash stations are present in the same room as the disinfection system.

System Monitoring Bureau of Land Management Southern Nevada District Health & Safety and Maintenance personnel are responsible for monitoring the RRCVC PWS. Utility Services, Inc. is the Distribution Operator (D-3) who oversees the system and collects monthly samples for Coliform bacteria and complies with the required sampling protocol according to the Nevada Division of Environmental Protection ‘Attachment A Nine Year Monitoring

Schedule’ for other contaminants derived from the Vulnerability Assessment Program.

For reference, the Total Coliform Sampling Plan and the water sampling schedule are provided in the Appendix to this Manual. However, if Coliform bacteria are detected, then re-sampling must take place, source water sampling must take place, and a Boil Water Notice will be issued, if required. The additional sampling would occur in conformance with the Total Coliform Sampling Plan to meet the requirements for compliance with the Total Coliform Rule and the Ground Water Rule. A blank Boil Water Notice is provided in the Appendix to this Manual. Bureau of Land Management has a history of working closely with the Southern Nevada Health District when Coliform has been detected or other issues have risen, using every resource to resolve the problem.

Chlorine residual is monitored biweekly from the Red Rock Canyon Visitor’s Center. This data is included in quarterly reports to Nevada Division of Environmental Protection.

Safety The operation and maintenance of water systems can be extremely dangerous. The combination of chemical use, electrical components and confined space issues create several potentially hazardous situations for a water supply system operator. Couple these inherent risks with the small system scenario in which an operator is often working alone, and a strong argument is made for establishing a safety program at every public water supply system, no matter how small.

The purpose of the RRCVC PWS safety program is to prevent accidents. Its success relies on the participation of everyone involved. Critical aspects of this safety program include:

Identification and correction of unsafe conditions Awareness and avoidance of unsafe acts

Unsafe conditions that may be encountered in RRCVC PWS include:

Electrical Hazards

Chemical Hazards Pressure Vessels Slips, trips and falls

Electrical Safety The bottom line for electrical safety is that only individuals knowledgeable in electrical systems and safety should be working on electrical equipment. BLM Southern Nevada District engineering and maintenance personnel are responsible for the continuous operation of the water system and when electrical repairs exceed their experience a licensed electrician shall be used for repairs made to the water systems electrical equipment.

Chemical Safety Safety Data Sheets (SDS) are provided with all hazardous chemicals purchased and must be made available to all individuals potentially exposed to the chemicals through handling or routine operations. These sheets describe specific materials compatibility, handling precautions, spill responses and hazardous properties of the chemical. Whenever working with chemicals, including the disinfection chemicals, the managers wear safety goggles. The area is equipped with an eyewash station.

Confined Space (Permit Required) Only individuals properly trained and current shall enter and work in a confined space as defined by the Code of Federal Regulations (CFR) Title 29 Part 1910.146 It is the responsibility of the system owners to identify confined spaces and manage confined space entry. The only individuals with access to the well buildings are BLM Support Services engineering and maintenance personnel, and the BLM Health & Safety officer.

System Appurtenances The system includes a water meter, treatment plant, and chlorination system located in the pump building.

- Meter calibration and meter replacement.

- Residential meters should be replaced in a ten-year cycle under good (no sand) conditions. Large/commercial meter calibration should take place every 2 years.

Emergency

Well Startup. (Site specific directions for pre-start safety checks, pump to waste, disinfection and water quality sampling before turning valves to pump into the system).

Before starting a dormant well into the distribution system, the well should be flushed three well volumes after which samples are collected. Once results are received and water quality meets compliance criteria the well can then be used in distribution.

Customer or User Complaints Every employee of the RRCVC PWS will be responsible for customer relations and for positive customer communication. Everything that an employee does from meter reading, installing pipelines, repairing lines, flushing, or answering consumer complaints has an effect on the public’s image of the utility. The employee is in the front lines of public relations. Therefore, the employee must be aware and take into account the responsibilities of public relations.

This added responsibility of representing our utility to the public means the employee must be careful to present a neat, efficient, knowledgeable, and cooperative image.

All employees working for the utility should have a basic knowledge of the system facilities and the system’s operation.

All water quality, pressure, or quantity complaints will be treated as legitimate and investigated as soon as possible. Questions will be asked as necessary to make sure the problem is understood. Every effort will be made to give the customer an immediate, clear and accurate answer to the problem. If the answer is not known, it will be referred to the proper person in the organization. Always inform the person with the problem what will be done to correct the situation or indicate when someone will call back with additional information. After the problem is corrected, a follow-up contact will be made to insure all is satisfactory and appropriate.

Valve Exercise Program System shut-off valves are provided primarily to isolate small areas for emergency maintenance, or to provide water from one zone to another during outages. Left to emergency-only operation, these valves would suffer from lack of operation rather than wear. A comprehensive program of inspection, exercising and maintenance of valves on a regular basis can aid in avoiding serious problems when the need to use a valve arises.

Routine valve inspections are conducted annually, and the following tasks performed should isolation valves be installed:

1. Verify the accuracy of the location of the valves on the system map.

2. Clean out the valve box.

3. Inspect valve stems and nut for damage or leakage.

4. Close the valve fully, if possible, and record the number of turns to the fully closed position.

5. Reopen the valve to reestablish system flows.

6. Note any problems.

7. Keep the valve log up to date. Valves generally turn 3 times the diameter of the pipe +/- 3 turns

Exercising (opening and closing a valve) will be done at the same time the valve inspection is made. The valve stem should never be left in a fully open or closed position.

After fully opening or closing a valve, back off the stem by one turn. Conditions will determine how often the valves should be exercised, but all valves will be exercised at least once a year. Any valves that do not completely close or open should be replaced.

Valves that leak around the stem will be repacked or replaced.

A timely maintenance program will be initiated to correct any problems discovered during this inspection and exercising process.

NOTE: Always operate valves slowly to prevent damaging pipes and valves. Always return valves to the normal operating position, to avoid damage to equipment or water outages to parts of the system.

Preventive Maintenance

1. Perform interior maintenance and cleaning of the pump area, pressure tank and well areas as needed.

2. Exercise all valves annually.

3. Replace bad sections of pipe as necessary.

Emergency Response Plan

PWS ID Number: NV 0005011

Introduction A disaster may occur at any time without warning. The Governor of Nevada or President of the United States may declare a state of emergency. A declaration of emergency will allow state and federal agencies to begin emergency relief procedures, however, these resources may not be available in large quantities for the first seventy-two hours, and may be insufficient to meet the needs of the RRCVC PWS. This Emergency Response Plan has been developed to ensure that drinking water will be available during the first seventy-two hours after an emergency has been declared.

Purpose The purpose of this plan is to establish guidelines for the RRCVC PWS to follow in the event of any emergency situation or disaster causing a prolonged interruption of water service.

The word disaster is defined for the purpose of this manual, as an event that exceeds the capability of the RRCVC PWS to handle that event. Three levels of emergency conditions may occur:

Normal: Everything is fine and the entity can handle the situation.

Alert: Minor emergency—something needs to be repaired but the entity can handle the situation without outside help.

Disaster: The entity can’t handle the situation and will need assistance from outside sources.

RRCVC has a good system map which is critical in the event of a disaster.

While it is likely that the RRCVC PWS will be inoperative in the event of a disaster, provisions for the delivery of safe water units will need to be considered. Portable toilets should also be considered.

General Emergency Response Actions If an emergency arises during business hours, the owner and managers should already be aware of the situation.

If it is an emergency situation that can be dealt with in a relatively short period of time, no further action will need to be taken. If it is an emergency that will affect water service for a long period of time, the RRCVC PWS will need to provide for potable water. If the emergency situation requires outside assistance, the managers will contact the appropriate entities.

The RRCVC will implement an emergency water supply contract. Potential suppliers include Water Pros, 2516 Losee Rd, North Las Vegas, NV 89030, (702) 316-9800. The contract must be awarded in accordance with the Federal Acquisition Regulations by a warranted federal Contracting Officer. The RRCVC certified Contracting Officer’s Representative (COR) will administer this contract.

Maximum Contaminant Level Exceedance It is the operator’s responsibility to review results of analyses whenever they are received from the lab. The results should be compared to the standards. If an exceedance occurs, action is required, and the Nevada Division of Environmental Protection Bureau of Safe Drinking Water (NDEP BSDW) will be notified. The operator will then work with the agency to agree on a plan of action.

Immediate action may be required in case of an exceedance or increased concentration of a contaminant having acute health effects, such as nitrate or nitrite. For certain contaminants, there are immediate notification and additional sampling requirements to be followed, for example if a routine total coliform sample is E.coli positive.

Implementation of cessation of water use at the RRCVC consists of closing off water main valves that supply the Visitor’s Center Complex and the Fee Station. A copy of the cessation notice will be posted at each restroom facility and drinking water/bottle fill station. Under this condition, water usage will be limited to handwashing and flushing toilets. The NDEP BSDW will be notified so that a plan of action can be agreed.

A Quick Reference Guide for the Public Notification Rule is available in the Appendix and electronically at http://www.epa.gov/safewater/publicnotification/pdfs/qrg_publicnotification.pdf The American Water Works Association (AWWA) sets many standards for various water system practices such as disinfecting water mains and wells.

Cross Connection Control Program

PWS ID Number: NV 0005011

Purpose The Cross-Connection Control Program exists in order for the RRCVC PWS Water System to fulfill its responsibilities under the federal Safe Drinking Water Act and State of Nevada regulations for the design, construction, operation and maintenance of public water systems. According to Nevada Revised Statute (NRS) 445A.860 water suppliers “may adopt such other regulations as may be necessary to govern the construction, operation and maintenance of public water systems if those activities affect the quality of water.” This program is developed in accordance with Uniform Plumbing Code as approved by the Director of Public Works and with the Nevada Administrative Code NAC 445A.67185 – NAC 445A.67255 which pertain specifically to cross-connections.

The purpose of this program is to protect the public water system from potential cross-contamination and/or pollution “backflowing” from a consumer’s private water system or internal distribution system.

This is accomplished through the:

1) Establishment and maintenance of a cross-connection control or backflow prevention program and;

2) Requirement to eliminate cross-connections or to install approved backflow prevention assemblies to minimize the possibility of contamination or pollution to the public water system, if a backflow or siphonage event were to occur, by confining potential contaminants or pollutants to the residence or facility of the consumer.

Authorization The RRCVC has the authority to establish and maintain a cross-connection control program under NRS 445A.860.

Responsibility It is the responsibility of the Bureau of Land Management Southern Nevada District (BLM) to protect the public water system from contamination and/or pollution due to the backflow of contaminants or pollutants through the water service connection. If, in the judgment of the Southern Nevada Health District an approved backflow prevention assembly is required at the consumer’s water service connection or within the consumer’s private water system for the safety of the public water system, the Southern Nevada Health District shall give notice in writing to the RRCVC an approved backflow prevention assembly(s) at a specific location(s) on the consumer’s premises. The consumer shall immediately install such an approved backflow prevention assembly(s) at the consumer’s own expense. Failure, refusal or inability on the part of the consumer to install, have tested and maintained a backflow prevention assembly(s), shall constitute grounds for discontinuing water service to the premises until such requirements have been satisfactorily met.

Shared Responsibility The water system is comprised of two parts:

1) the Water Supplier’s System and,

2) the Consumer’s System

NOTE: The Water Supplier and Consumer are both BLM

Protection of the potable water system is the BLM’s responsibility. It is the responsibility of the BLM to maintain compliance with federal and state drinking water standards and protect public health; simultaneously it is the responsibility of the consumer to prevent pollution and contaminants from entering the public water supply from their facility or residence.

The BLM is responsible for maintenance and protection of the source facilities, the distribution system and facilities owned and controlled by the utility. The BLM is responsible for their water piping system after the water meter or connection to the public water system. It is the consumer’s responsibility to report any possible hazard that may affect the BLM’s water mains. Reports should be made to the Southern Nevada Health District as soon as a hazard is detected.

Policy New unprotected cross-connections are prohibited where a hazard has been identified.

No new water service connections shall be made unless equipped with an approved backflow prevention assembly. The assembly will be tested and properly functioning prior to the issuance of a certificate of occupancy for any building. All new nonresidential construction plans and specifications shall be made available to the NDEP BSDW for review to determine the health hazard and level to the RRCVC Water System.

Existing cross-connections are to be protected. An approved backflow prevention assembly shall be installed on all existing cross-connections where a hazard has been identified to the RRCVC Water System upon notification of the need for installation from the Southern Nevada Health District.

Optional Service (Containment) Distribution Protection BLM prefers to utilize an external cross-connection control program. External cross-connection control programs consist of backflow protection at the meter or service connections. Implementation of an external cross-connection control program may necessitate installation of a hot box, electrical wiring, and protective bollards depending on the winter climate.

Initial Notification Southern Nevada Health District will identify facilities that may potentially require backflow protection based on NAC and known hazards. Southern Nevada Health District will then notify the BLM in writing of the need for a survey to identify potential hazards. Southern Nevada Health District will follow up with a telephone call to schedule an appointment for the survey.

Notification to Install an Approved Backflow Prevention Assembly Once a survey has been completed the BLM will be notified in writing of the need to install a backflow prevention assembly.

The letter will state:

a. The requirement for installation of an approved backflow prevention assembly;

b. The health hazard level or non-health hazard level which has been identified for that customer by Southern Nevada Health District based upon the use of their residence, facility or premises;

c. The type of approved backflow prevention assembly required;

d. The location in which the device shall be installed; and

e. The date by which it must be installed and tested.

Consumers will have 90 days following the mailing of the initial compliance notification to install and test approved assemblies or air gaps.

Maintenance of Records The BLM Supervisory Operations Specialist is responsible for monitoring the cross-connection control program and maintaining records tracking all primary assemblies. This includes maintaining records regarding annual testing, repairs and retesting events. The BLM Supervisory Operations Specialist will establish a database for program record keeping. The BLM Supervisory Operations Specialist plans to use a computer spreadsheet or database for tracking assemblies, testing schedules, and assembly repairs. The BLM Supervisory Operations Specialist will retain all assembly test and repair records for a period of three (3) years.

Annual Backflow Prevention Assembly Testing and Repairs Backflow prevention assemblies must be tested annually by a Certified Backflow Tester holding an American Water Works Association (AWWA) certification, American Backflow Prevention Assembly (ABPA) or State of Nevada approved backflow certification. When an assembly is moved, or removed and replaced, or an assembly is repaired, it must then be tested. All repairs must take place within 7 days Records maintained by the BLM Supervisory Operations Specialist will include:

a) Name, address, and telephone number of the person who performed the test;

b) A copy test with information on the tester’s current valid American Water Works

Association (AWWA), American Backflow Prevention Association (ABPA) or State of Nevada approved backflow assembly tester certification.

c) IF A REPAIR: Parts replaced including part number and manufacturer name;

d) IF A REPAIR: Name, address, and telephone number of the person who performed the repair or moved the assembly, or of the responsible person at customer service.

Backflow Prevention Assembly Requirements New Installation or Replacement Installations Backflow prevention assemblies which may be utilized for new or replacement installations must be included in the University of Southern California Foundation for Cross-Connection Control Hydraulic Research (USC FCCCHR) or State of Nevada approved list of approved assemblies in effect on the date of installation. All assemblies that have been approved by USC FCCCHR have gone through extensive laboratory testing and one year of field testing prior to approval.

Existing Assemblies For existing assemblies, the BLM Supervisory Operations Specialist will maintain documentation showing that the assembly is included in the current USC FCCCHR or

State of Nevada approved list of approved assemblies or was included in the USC FCCCHR or State of Nevada approved list of approved assemblies on the original installation date. Approval must be obtained from the BLM Supervisory Operations Specialist before a backflow prevention assembly is removed, relocated or replaced.

Existing assemblies which were included in the USC FCCCHR or State of Nevada approved list of approved assemblies upon installation, but which are no longer listed may continue to be used in the same application and location, for as long as annual test results indicate that the assembly is functional. De-listed assemblies that fail must be replaced.

De-listed assemblies may not be moved.

Air Gaps Air gaps must comply with Uniform Plumbing Code requirements.

Consumer’s Responsibilities for Backflow Prevention Assembly Installation, Maintenance and Testing All backflow prevention assemblies required by the Southern Nevada Health District must be installed and maintained on the consumer’s premises as part of the consumer’s water system. Ownership, installation, testing and maintenance of the assembly and all associated costs are the responsibility of the consumer.

Consumers shall have a certified tester test the assembly system for proper operation and results will be submitted in writing to the Southern Nevada Health District. Testing of backflow prevention assemblies will be done only by a certified backflow prevention assembly tester.

All backflow prevention assemblies will be installed in accordance with the manufacturer’s instructions. Any bypass around a backflow prevention assembly at any time, including when the assembly is in need of testing, repair or replacement, is prohibited. When it is not possible to interrupt water service, the customer will provide for the parallel installation of an approved backflow prevention assembly.

Compliance & Termination of Service In an attempt to avoid discontinuing service the Southern Nevada Health District will notify customers 60 days prior to their annual testing date and/or installation date and again at 30 days prior to their annual testing date and/or installation date. On the annual testing date or the installation date the Southern Nevada Health District will notify the customer that water service will be disconnected within 30 days if program requirements are not met.

The Southern Nevada Health District will disconnect service to customers who fail to comply with any requirement of this program. Program requirements include:

1) Installation and testing of approved assemblies or air gaps at the location(s) determined by the Southern Nevada Health District within 90 days following mailing of the initial compliance notification.

2) Annual testing of assemblies or air gap inspection report and receipt of results within 90 days of mailing the testing compliance notification letter. The Southern Nevada Health District will notify customers 60 days prior to the annual testing date and again 30 days prior to the annual testing date.

3) Backflow assembly testers must hold a current Backflow Assembly Tester Certificate issued by the AWWA or ABPA.

4) All repairs needed must be accomplished and re-tested within the 7 days time period.

5) Notification to the Southern Nevada Health District upon repair of an assembly including receipt of test results within 30 days following the activity.

6) Maintenance of installed assemblies in good working condition.

7) Approval must be obtained from the Southern Nevada Health District before a backflow prevention assembly is removed, relocated or replaced. The Southern Nevada Health District must receive test results within 30 business days following the activity.

Implementation The Southern Nevada Health District plans to inspect facilities within their jurisdiction and distribution area to determine the potential risk of cross-connection and backflow.

The Southern Nevada Health District will:

1) Survey the public water system owned backflow prevention assemblies and establish compliance.

2) Survey all RRCVC Water System owned and operated water production, storage, and distribution systems to identify potential cross-connections and evaluate the degree of hazard. Where needed approved backflow prevention assemblies will be installed and tested or air gaps will be installed.

3) Implement an information program, which may include conducting meetings with residents and business owners, informational pamphlets included with water bills, and information booths at town festivities.

4) Require all new construction to comply with State of Nevada regulations.

5) Create and review a priority list: The RRCVC Water System will review service connection records to evaluate user activities to determine which service connections or taps within the places served require protection from cross-connection. Priority will be assigned to each connection reviewed based on the degree of hazard (health/non health).

a. First priority connections are those where a health hazard is determined to exist, or that require protection from cross-connection in accordance with the Uniform Plumbing Code.

b. Second priority connections are all other service connections.

6) The RRCVC Water System will follow the State of Nevada regulations to determine the minimum type of protection that is required for different categories of service connections according to NAC 445A.67195 to 67215

7) Conduct onsite water use surveys of its facilities beginning with the highest priority user identified. The attached Field Survey Form, or equivalent, will be used. A Nevada Division of Environmental Protection (NDEP) Official may be requested to conduct joint surveys.

8) Require consumers or owners of the property to install an air gap or approved backflow prevention assembly(s) where necessary according to Nevada regulation and to test annually.

9) Require consumers to notify the Southern Nevada Health District of any changes or repairs made to the plumbing system, and the Southern Nevada Health District will conduct an onsite survey to determine requirements for protection from cross-connections.
