1 PROJECT DESCRIPTION

1.1 DESCRIPTION OF WORK

The Contractor shall furnish all supervision, labor, vehicles, equipment, materials, chlorine, fuel, and incidentals required to source, haul, chlorinate, test, and deliver bulk water to the North Rim water storage tanks at Grand Canyon National Park under a firm-fixed-price award. The

Contractor shall deliver 662,000 gallons of water (CLIN 00010)to the unloading point at the storage tanks by the base completion date in Section 4.1, following the delivery schedule in

Section 4.2. The Government may exercise an option for an additional 338,000 gallons for the

North Rim (CLIN 00020).

The water will be used to complete the restoration of the park’s North Rim water and wastewater systems — to jet sanitary sewer lines, start-up and commission the Temporary Wastewater

Treatment Plant, and to pressurize, flush, and disinfect the water distribution system — while the

North Rim’s own water supply is out of service after the 29 August 2026 flood. The water will be posted as non-potable and will not be used for drinking until the Government flushes, disinfects, and tests the system and returns it to potable service. The Contractor shall nevertheless source, handle, and haul the water as drinking water, as Arizona’s hauled water rule and National Park Service (NPS) policy require (Section 4.8).

The Contractor shall determine the number and size of vehicles, the staffing, and the methods needed to meet the delivery schedule, subject to legal load limits and the requirements of this

Statement of Work (SOW).

Key deliverables are the delivered water, non-potable water signage, chlorine dosing and field testing of every load, a delivery record for every load, and daily reports.

1.2 LOCATION

- Grand Canyon National Park, North Rim, Coconino County, Arizona 86052.

- Unloading point — the fill connection for the North Rim water storage tanks, adjacent to the North Rim Emergency Services Building on State Route (SR) 67; 36.215117, -

112.058433 (36° 12.907′ N, 112° 3.506′ W); elevation 8,366 feet [location, connection, and coordinates are from the 2023 North Rim water hauling contract — verify for 2026].

- Access — US Highway 89A to Jacob Lake, then SR 67 south to the North Rim. SR 67 is the only paved road to the North Rim developed area.

1.3 BACKGROUND

According to the Superintendent’s Letter of Compliance Completion (Planning, Environment and Public Comment (PEPC) project 138479, 4 September 2026), a flash flood in Bright Angel and Roaring Springs Canyons on 29 August 2026 damaged the Transcanyon Waterline, which supplied water to the North and South Rims. The flood also left the Roaring Springs Pump

House, the North Rim’s water supply, inoperable.

The Government is restoring North Rim utilities damaged in the 2025 Dragon Bravo Fire under a separate contract, and the lack of water affects that work.

According to the Government’s engineer, the Arizona Department of Environmental Quality

(ADEQ) is comfortable with hauling water to the North Rim storage tanks under these conditions: the water comes from a community water system; the water is posted, with abundant signage, as non-potable; and ADEQ is notified and actively engaged during hauling. The engineer also requires the source water system’s name and identification number to perform a water quality review, and requires that residual chlorine and pH be measured before each truck unloads. After consulting ADEQ on the park’s other hauled water operations, the park also requires that hauled water come only from groundwater sources.

Hauled water delivered to a public water system in Arizona is regulated under Arizona

Administrative Code (A.A.C.) R18-4-214 (Reference 1). NPS policy on potable water hauling is in Reference Manual 83A (RM-83A), Chapter 1, Section 10.0 (Reference 2). NPS owns and operates the North Rim public water system and retains responsibility for its compliance and for coordination with ADEQ (Section 5).

Water has been hauled to the North Rim before. In April 2017, a vendor hauled water to the storage tanks after major damage to the pipeline. After that event, the Arizona Department of

Transportation (ADOT) studied SR 67 and raised its allowable gross vehicle weight from 20,000 pounds to 80,000 pounds. In 2023, the park contracted for water hauling to the storage tanks from a regulated public water system after a break in the pipeline from Roaring Springs.

No ground disturbance, vegetation removal, or new construction is anticipated. The Contractor shall notify the Contracting Officer’s Representative (COR) and the Contracting Officer (CO) if ground disturbance becomes necessary. Work in the park will occur on park roads, at the unloading point, and in areas the COR or CO designates.

2 BASE AWARD

The base award (CLIN 00010) is a firm-fixed price for the delivery of 662,000 gallons of water to the North Rim storage tanks by the base completion date in Section 4.1. Each task in this section is included in the firm-fixed price.

4 PROJECT REQUIREMENTS

4.1 PERIOD OF PERFORMANCE

Key dates. The dates below apply to the base award (CLIN 00010)and both options. Each date is stated only in this table; other sections refer to it.

Milestone Date Base award: base quantity delivered and base period ends (the base completion date) 29 October 2026

(CLIN 00020): last day for the CO to exercise 15 March 2027 (CLIN 00020): option quantity delivered (the (CLIN 00020) completion date) 15 May 2027

SR 67 winter closure, Jacob Lake to North Rim (ADOT; Reference 3) 7 December 2026

Base period. From Notice to Proceed through the base completion date in the table above.

Mobilization. The Contractor shall not deliver water from a source until the Government approves the source (Section 4.4), and shall not use a truck until the Government has inspected it

(Section 4.8). The source identification package and the signage submittal are required with the proposal, so that both are approved before the first delivery.

Option. If the CO exercises (CLIN 00020), the Contractor shall deliver the option quantity by the (CLIN 00020) completion date in the table above, and shall submit a revised delivery schedule within 7 calendar days after the option is exercised (Section 3).

Winter closure of SR 67. ADOT closes SR 67 between Jacob Lake and the North Rim for the winter on the date in the table above (Reference 3). Any delayed deliveries must be complete before the closure. If ADOT closes SR 67 before all deliveries are complete due to unforeseen weather events, the Contractor shall notify the CO immediately. The CO will determine how any undelivered quantity will be delivered.

4.2 DELIVERY SCHEDULE

Proposed delivery schedule. The Contractor shall submit a proposed delivery schedule showing the loads and gallons it will deliver each delivery day to meet the milestones. The Contractor shall provide the schedule to the COR and the CO jointly. The Contractor shall propose any change to an accepted schedule in writing at least 72 hours before the change takes effect. An accepted schedule does not change the base quantity or the milestones.

Time. A delivery day runs from 0000 to 2359 Mountain Standard Time (MST). Arizona does not observe daylight saving time (Reference 4). All records shall use MST, including fill times recorded at any source in Utah, which observes daylight saving time until 1 November 2026.

4.3 WORK HOURS

Deliveries are permitted 7 days per week, including weekends and Federal holidays, between

0600 and 1900 MST, unless the COR approves other hours. The Contractor shall coordinate unloading times through the COR so that deliveries do not interfere with other contractors working in the North Rim developed area.

When a Government inspector is present, no load shall be unloaded without the inspector’s approval (Section 4.5).

4.4 SOURCE WATER

Source requirements. The Contractor shall obtain all water from a source that meets all of the following:

- It is a regulated public water system, or a source approved under 18 A.A.C. 5, Article 5

(Reference 1, subsection A), and it meets the requirements of the Safe Drinking Water

Act (Reference 2, Section 10.1).

- It is a community water system — a public water system that serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents (Reference 5, § 141.2). This is one of ADEQ’s conditions for hauling (Section

1.3).

- A surface water or ground water under the direct influence source may be utilized.

- The source utility has authorized, in writing, the Contractor’s fill point and the volumes needed for this contract.

For example, water for drainfield testing at the North Rim in April 2026 came from a hydrant on the Kanab City, Utah, municipal system, which the Government’s engineer found meets the community water system.

The Contractor may propose any source that meets these requirements.

Source approval. Before the first delivery from a source, the Contractor shall submit a source identification package (Section 6.1) that contains:

- the public water system’s name and identification number;

- written confirmation from the source utility that the system is a community water system;

- the system’s most recent Consumer Confidence Report (Reference 5, § 141.151) for the past three years; and

- the fill location — bulk water station or hydrant — and the source utility’s written authorization for the fill point and the volumes.

The Government’s engineer will use the package to perform a water quality review. The

Government will review each package within 3 business days after receipt. No water from a source shall be delivered until the Government approves the source in writing. The Contractor may propose an alternate source at any time; the same requirements apply.

Laboratory testing. Because the Government will flush, disinfect, and test the North Rim system before returning it to potable service, this SOW does not require laboratory analysis of source water or of delivered loads.

4.5 CHLORINATION AND FIELD TESTING

Chlorine. The Contractor shall use a chlorine disinfectant certified to NSF/ANSI/CAN 60

(Reference 6). Sodium hypochlorite shall also conform to ANSI/AWWA B300 (Reference 7).

The Contractor shall add chlorine at the time each load is filled if needed to achieve the target residual defined in the Acceptance Criteria table.

Test equipment. Each vehicle shall carry a free chlorine test kit that uses a DPD colorimetric method, such as Hach Method 8021, and reads at least 0.2 to 1.0 mg/L, and a pH meter or pH test kit. The Contractor shall calibrate each instrument as the method or manufacturer specifies, check it each day of use, and keep the calibration and check records.

At fill. For each load, the Contractor shall:

- record the date and time;

- uncap the connections and spray them with a 200 mg/L (200 ppm) sodium hypochlorite solution;

- flush the hydrant or fill valve before connecting any hose (Reference 2, Section 10.10);

- measure and record the free chlorine residual of the source water before loading, so that the chlorine dose accounts for it;

- add chlorine (if needed) and fill the transport tank through the backflow-protected fill connection (Section 4.8);

- measure and record the free chlorine residual after dosing, and record the type and quantity of chlorine added;

- measure and record the pH after dosing

- cap all hoses and connections; and

- record the departure time.

At off-load. For each load, before unloading, and witnessed by the Government inspector when present, the Contractor shall:

- record the arrival date and time;

- uncap the connections and spray them with a 200 mg/L sodium hypochlorite solution;

- measure and record the free chlorine residual, as A.A.C. R18-4-214(F) requires at each off-load, and the pH (Reference 1, subsection F);measure and record the pH

- check the water’s appearance and odor;

- begin unloading only when the results meet the acceptance criteria in Section 4.6 and, when an inspector is present, the inspector approves;

- after unloading, record the meter readings and gallons delivered, and sign the delivery record, with the Government inspector’s signature when present; and

- cap all hoses and connections, and restore the unloading connection to a capped, secured condition.

Loads held over. If a load remains in a transport tank more than 24 hours after fill, the

Contractor shall measure its free chlorine residual at least every 24 hours until off-load, to confirm the residual Arizona requires at all times (Reference 1, subsection F).

4.6 DELIVERY ACCEPTANCE

Acceptance criteria. Each load shall meet the following criteria before it is unloaded:

Parameter Criterion Free chlorine at fill, before dosing

0.2 mg/L, minimum

Free chlorine at fill, after dosing

Dosed to ensure that “Free chlorine at off-load” is satisfied.

Free chlorine in transit 0.2 to 1.0 mg/L at all times (Reference 1, subsection F) Free chlorine at off-load 1.0 – 1.5 mg/L pH at off-load 7.5 – 8.5 Appearance and odor at off-load Clear and colorless, with no visible particles, sheen, or objectionable odor

Accepted loads. A load is accepted when all of the following are met:

- It was filled at a source the Government has approved (Section 4.4) and carried in a truck the Government has inspected (Section 4.8).

- It was dosed with chlorine and tested at fill.

- It met the acceptance criteria at off-load.

- It was unloaded at the unloading point, and its metered volume is recorded on a delivery record signed by the Government inspector or, when no inspector was present, accepted by the COR within 1 business day.

Quantity and invoicing. Only accepted gallons, as measured by the Contractor’s meter (Section

4.9) and recorded on delivery records, count toward the base quantity and the milestones. The final delivery may be a partial load. Gallons delivered beyond the base quantity before the CO exercises (CLIN 00020) or issues a modification will not be accepted. Each invoice shall include copies of the signed delivery records for the accepted loads it covers (Reference 8, FAR 52.232-

1).

Nonconforming loads. A load that does not meet an acceptance criterion shall not be unloaded.

The Contractor shall dispose of a rejected load outside the park, or at a location the COR designates, in compliance with applicable discharge requirements. A rejected load does not count toward the base quantity or a milestone. The Contractor shall record the reason for each rejection and the corrective action taken. After 2 rejected loads from the same truck or source, the

Contractor shall stop using that truck or source until the cause is corrected and the COR approves its return to service.

4.7 RECORDS AND REPORTING

Delivery record. The Contractor shall complete a delivery record, on paper or electronically, for each load. Together, the delivery records serve as the hauling log that A.A.C. R18-4-214(F) requires and as the hauling records that RM-83A requires (Reference 1, subsection F; Reference

2, Section 10.4). Each record shall include:

- load number, truck identification, and driver name;

- source name, fill point, and the date and time of filling;

- type and quantity of chlorine added, and the free chlorine residual at fill;

- departure time, and arrival date and time at the unloading point;

- free chlorine residual and pH at off-load, and the appearance and odor check;

- meter readings and gallons delivered;

- acceptance or rejection, and the reason for any rejection;

- signatures of the driver and, when present, the Government inspector; and

- any remarks the driver considers pertinent.

Reports. The Contractor shall provide the following:

- Daily report — by 0900 the following day, to the CO, the COR, and the North Rim

Project Manager or their designee: loads and gallons delivered, cumulative gallons accepted against the current milestone, rejected loads, and incidents, with copies of that day’s delivery records.

- Weekly log copies — copies of the week’s hauling log and sanitation log, each week on the day the COR designates.

- Immediate notice — to the COR and the CO by phone within 1 hour, and in writing within 24 hours, of any rejected load, spill, or accident, and of any event that may prevent the Contractor from meeting a milestone, such as a road closure, a source restriction, or a vehicle breakdown.

Records. The Contractor shall:

- keep on board each vehicle, on paper or electronically, the hauling log; the water source location and the dates and times of loading and unloading; the written cleaning and disinfection procedures and the sanitation log; and copies of permits, licenses, and source authorizations (Reference 1, subsection F; Reference 9);

- make all records available to the Government and to ADEQ on request (Reference 1, subsection F; Reference 2, Section 10.4);

- keep hauling logs at least 3 years (Reference 1, subsection F), and keep all contract records for 3 years after final payment (Reference 8, FAR 4.703); and

- deliver a complete record set to the COR at closeout.

The Government has unlimited rights in all data first produced under this contract (Reference 8, FAR 27.404-1).

4.8 HAULING EQUIPMENT AND SANITATION

These requirements apply to every transport tank, pump, hose, fitting, valve, and appurtenance used under this contract. A “transport tank,” as used in this SOW, is a tank on a Contractor truck or trailer that holds water hauled under this contract (a “water transport container” under A.A.C.

R18-4-214). This section does not apply to the park’s storage tanks. Where A.A.C. R18-4-214, RM-83A, and this SOW differ, the most stringent requirement governs.

Arizona hauled water rule. A.A.C. R18-4-214 applies to every load (Reference 1):

- (A) “All hauled water for delivery to a public water system shall be obtained from a source that is approved pursuant to 18 A.A.C. 5, Article 5, or a regulated public water system.”

- (B) “Materials or products that come into contact with the water shall comply with R18-

4-213(B).” A.A.C. R18-4-213(B) requires conformance to ANSI/NSF Standard 61

(Reference 10).

- (C) “Roof hatches shall be fitted with a watertight cover.”

- (D) “A bottom drain valve or other provisions to allow complete drainage and cleaning of a water transport container shall be provided.”

- (E) “Hoses that are used to deliver drinking water shall be equipped with a cap and shall remain capped when not in use.”

- (F) “A water hauler shall, at all times, maintain a residual free chlorine level of 0.2 mg/l to 1.0 mg/l in the water that is hauled in a water transport container. A chlorine disinfectant shall be added at the time water is loaded into the container. The residual free chlorine level shall be measured each time water is off-loaded from the container. The water hauler shall maintain a log of all on-loading, chlorine disinfectant additions and residual-free chlorine measurements. Such records shall be maintained for at least three years and made available to the Department for review upon request.”

- (G) “A water transport container shall be for hauling drinking water only. The container shall be plainly and conspicuously labeled ‘For Drinking Water Use Only.’”

NPS potable water hauling policy. The Contractor shall also meet the following requirements of RM-83A, Chapter 1, Section 10.0 (Reference 2):

- (10.2) Transport tanks shall be constructed of non-toxic, non-porous materials and shall never have been used for storing or hauling anything but potable water. NSF-approved containers are recommended.

- (10.5) A transport tank that has not been used for more than one day shall be flushed before it is used to haul water. The Contractor shall provide its hauling procedures to the park and the NPS public health consultant on request. Primary agency protocols shall be followed.

- (10.6) At no time during filling shall a potential for backflow exist.

- (10.7) Hoses used to fill and empty transport tanks shall be identified and used only for potable water. Hose ends shall be capped when not in use, and the caps shall be attached to the hoses.

- (10.8) All tanks, hoses, fittings, and other equipment used to store, haul, or transfer water shall be constructed of approved food-grade materials or coated with approved food-grade coatings.

- (10.9) Hoses shall be stored so that they are not subject to contamination from surface runoff, birds, rodents, and other sources.

- (10.10) All valves and fire hydrants shall be flushed before any hose is connected.

- (10.11) Bacteriological testing of transport tanks is not required under this contract, because the source is a community water system with a bacteriological monitoring program and the Government will perform bacteriological sampling of the North Rim system before returning it to potable service.

Separate system and labeling. The Contractor shall meet the following:

- The hauled water system — fill hoses and lines, pumps, transport tanks, and discharge piping — shall be separate from any other water system.

- Each transport tank shall be plainly and conspicuously labeled “For Drinking Water Use

Only” (Reference 1, subsection G). Because Arizona sets this labeling standard, its wording governs over the RM-83A wording (Reference 2, Section 10.0). Hoses shall be labeled “potable water.”

Materials. All water-contact materials and coatings, including gaskets, lubricants, and hose linings, shall be certified to NSF/ANSI/CAN 61 (Reference 11). Water-contact surfaces shall be smooth, non-corrodible, and non-absorbent. Galvanized pipe and fittings, cast-iron pumps, and petroleum-lubricated pumps shall not be used.

Transport tank construction. Each transport tank shall meet the following (Reference 9):

- It shall close to exclude foreign matter and shall be vented. Vents shall face downward and shall be protected by a 30-mesh screen of non-toxic, non-absorbent material.

- It shall have at least one roof hatch that allows interior inspection and cleaning, fitted with a watertight cover (Reference 1, subsection C).

- Its inlets and outlets shall have threaded or clamped caps tethered to the ports, in place except while water is being loaded or discharged.

- It shall have a bottom drain that allows complete drainage and cleaning (Reference 1, subsection D). No pipe carrying a non-potable liquid shall pass through the tank.

Filling and backflow. The Contractor shall:

- fill only at the source utility’s bulk water station, or at a hydrant the source utility authorizes in writing, from water under pressure;

- protect each fill against backflow, consistent with A.A.C. R18-4-215 (Reference 12), by either an air gap — the fill pipe ending at least 1 inch, or twice the fill pipe diameter, whichever is greater, above the highest water level the tank can reach (Reference 13) — or a backflow prevention assembly approved under A.A.C. R18-4-215(D), with no branch between the assembly and the tank inlet. Where the source utility requires a higher level of protection, that requirement governs; and

- use sanitary transfer techniques, keep foreign material out of the water, and never submerge a hose or pipe in a receiving vessel.

Sanitation. The Contractor shall:

- clean and disinfect transport tanks, pumps, hoses, valves, and fittings per ANSI/AWWA

C652 (Reference 14) before first use under this contract; after 72 hours or more of non-use; after any possible contamination, including open covers or caps, or entry of dust, smoke, rain, or chemicals; and after any defect appears in a seal, vent, hatch, valve, pump, or hose;

- after disinfection, drain and flush with potable water before filling;

- keep written cleaning and disinfection procedures, stating the agents, concentrations, and contact times, on each vehicle; and

- keep a sanitation and maintenance log on each vehicle that shows the method and frequency of cleaning (Reference 2, Section 10.4).

Truck inspection. Before first use under this contract, the Contractor shall present each truck for

Government inspection at a location the COR designates. The Government may require the transport tank to be empty for interior inspection. The Government will inspect items (C), (D), (E), and (G) of A.A.C. R18-4-214, and the Contractor shall furnish documentation of items (A) and (B). The Government will use the following checklist, adapted from Coconino County’s

Water Hauler Truck Inspection Information Sheet (Reference 15):

- the source is approved under Section 4.4;

- the transport tank has been used only for potable water and has never held any other product (Reference 2, Section 10.2; Reference 1, subsection G);

- the transport tank is labeled “For Drinking Water Use Only”;

- the transport tank, its coating, and every other part that contacts the water are certified to

NSF/ANSI/CAN 61;

- the transport tank has a roof hatch with a watertight cover, a screened vent, and a bottom drain;

- hoses are certified to NSF/ANSI/CAN 61, labeled, clean, in good repair, and capped when not in use;

- the truck carries chlorine certified to NSF/ANSI/CAN 60, a free chlorine test kit that reads 0.2 to 1.0 mg/L, and a pH meter or kit, and the operator shows how to use them;

and

- the truck carries the hauling log, the sanitation log, and the written cleaning and disinfection procedures.

The Government may inspect any vehicle and its records at any time.

4.9 DELIVERY AND UNLOADING OPERATIONS

Unloading point. The Contractor shall unload only at the unloading point in Section 1.2 and shall connect only to the Government-furnished 2-inch female camlock at that point (Section 5).

If changes are required to the connection point, the government will provide the details in writing with a 3-day advance notice. The Contractor shall make no other connection to park facilities.

No Contractor equipment, including pumps, meters, hoses, and backflow prevention assemblies, shall connect to park facilities until the Government approves the related submittals (Section 6).

Unloading equipment. The Contractor shall furnish pumps, hoses, and fittings that connect to the Government-furnished coupling and can fill the storage tanks. Hoses and fittings shall be certified to NSF/ANSI/CAN 61 and used only for drinking water.

Backflow protection at the unloading point. The Contractor shall:

- furnish, install, and maintain at the unloading connection a reduced pressure principle backflow prevention assembly that conforms to ASSE 1013 (Reference 16) and holds a current certificate of approval from the University of Southern California Foundation for

Cross-Connection Control and Hydraulic Research (Reference 17), or another method the park’s Cross-Connection Control Program accepts in writing;

- have the assembly tested before first use, and after any relocation or repair, by a person currently certified as a general backflow tester by the California-Nevada Section of the

American Water Works Association, the Arizona State Environmental Technical

Training (ASETT) Center, or another certifying authority ADEQ approves (Reference 12, subsection F), and submit each test report to the COR; and

- sanitize hose ends and fittings before each connection.

Metering. The Contractor shall measure every load with a totalizing meter, on the transport tank’s discharge line or at the unloading connection, that meets the tolerance for water in

National Institute of Standards and Technology (NIST) Handbook 44, Section 3.31 (Vehicle-

Tank Meters), Accuracy Class 1.5 (plus or minus 1.5 percent) (Reference 18). The Contractor shall test each meter against a volume standard traceable to NIST before first use, and when the

COR asks, and shall give the results to the COR.

Other work at the North Rim. Other contractors are restoring utilities in the North Rim developed area. The Contractor shall coordinate access, staging, and unloading times through the

COR, and shall not interfere with their work.

Contractor-furnished items. The Contractor shall furnish all water, chlorine, fuel, equipment, and personnel. Government fuel is not available.

4.10 NON-POTABLE WATER SIGNAGE

One of ADEQ’s conditions for hauling is abundant signage that states clearly that the water is non-potable. The Contractor shall:

- prepare a signage submittal (Section 6.1) that shows the sign wording, layout, symbol, size, material, quantity, locations, and mounting method; the Government will route it to

ADEQ, and no sign shall be installed until NPS and ADEQ approve it;

- furnish 3 signs reading “NON-POTABLE WATER — DO NOT DRINK,” with a “do not drink” symbol and Spanish text; off-the-shelf signs are acceptable;

- make each sign of rigid, weather-resistant and ultraviolet-resistant material, at least 12 by

18 inches;

- install the signs at the North Rim storage tanks, the unloading point, and other locations the COR designates, on existing structures, fences, or freestanding bases, without ground disturbance;

- install the approved signs before the first delivery; and

- replace any damaged or missing sign within 2 calendar days, until the final delivery.

The signs shall remain in place at completion and become Government property. The

Government will remove them when it returns the system to potable service.

4.11 PERSONNEL, PERMITS, AND DRIVER HOURS

Supervision. The Contractor shall designate one (1) supervisor and one (1) alternate, each reachable at all times when operations are active.

Drivers. Each driver shall hold a commercial driver’s license (CDL) of the class, and with the endorsements, that the vehicle requires, including the tank vehicle (N) endorsement for a tank vehicle. The Contractor and its drivers shall comply with 49 CFR Parts 382, 383, and 390 through 399 as they apply, including as Arizona adopts them for intrastate carriers (Reference

19; Reference 20).

Hours of service. Drivers shall comply with the hours-of-service rules in 49 CFR Part 395, including any exception in 49 CFR 395.1 that applies to the driver (Reference 19). Emergency hours-of-service relief is not expected to apply to this work. The Contractor shall staff and schedule drivers to meet all normal requirements.

Chlorination and testing staff. Staff who add chlorine or test water shall be trained in the

Contractor’s chlorine dosing procedure (Section 6.1). Contractor staff shall not make process control decisions for the park’s water system.

Permits and authorizations. The Contractor shall:

- obtain and maintain all permits, inspections, and certifications that apply to potable water hauling vehicles. Coconino County does not currently license or inspect water haulers
