Statement of Work

Liquefied Natural Gas Station Maintenance

August 2, 2016

PART 1 – GENERAL

a. Purpose

The National Park Service (NPS) at Grand Canyon National Park (GRCA) owns and utilizes a liquid natural gas/liquid to compressed natural gas (LNG/LCNG) fueling station located on the park’s South Rim. The NPS relies on the station to provide CNG fuel to NPS and NPS concessioner vehicles. Vehicles fueled at the station are primarily large transit and tour buses operated by the park’s South Rim transportation system operations contractor (approximately 30

CNG transit buses) and the park’s South Rim hospitality contractor (approximately 20 CNG tour buses). The station also has a vaporization system to send low-pressure natural gas to a nearby administrative and maintenance complex of buildings for heating purposes.

An operational and well maintained LNG/LCNG is essential to NPS operations at GRCA. The

GRCA visitor transportation system is operated entirely by CNG buses. The system operates year round in the park’s South Rim village area providing service to more than 7 million riders annually. The transportation system is a critical part of the visitor experience with some areas of the South Rim only accessible by shuttle bus. Any issues or problems taking the LNG/LCNG station out of service for more than 24 to 48 hours would cause an unacceptable shut down of the visitor transportation system. In addition, the park’s maintenance, administrative and wildland fire complex rely on the station for heat.

It is therefore essential that the Contractor maintain the LNG/LCNG station in good working order and in accordance with all applicable municipal, county, state and federal regulations, codes, laws, ordinances, standards, rules, supplements and industry standards in force during the period of the contract. In addition, the park’s Contracting Officer’s Representative (COR) and the Contractor must establish and maintain good communications to ensure that park operations are not unacceptably interrupted.

b. Background

The NPS preserves unimpaired the natural and cultural resources and values of the National Park

System for the enjoyment, education, and inspiration of this and future generations. The NPS cooperates with partners to extend the benefits of natural and cultural resource conservation and outdoor recreation throughout this country and the world. For basic information about the NPS and its mission please visit http://www.nps.gov.

Grand Canyon National Park encompasses approximately 1,218,375 acres of public land in the southern end of the Colorado Plateau. It is a globally significant natural resource containing scenic vistas known throughout the world. In recognition of its significant values, GRCA was designated as a world heritage site in 1979. More than five million people from around the world http://www.nps.gov/ visit GRCA, with most people visiting the park’s South Rim. For basic information about

GRCA, please visit the park’s website at http://www.nps.gov/grca. For more specific information, please also see the park’s 2014 park profile at http://www.nps.gov/grca/learn/management/upload/2014-grca-park-profile.pdf.

The LNG/LCNG station has been in operation since 2001 and consists of an LNG storage tank, an LNG dispenser, and associated pumps. A LCNG capability exists at the station and incorporates an LCNG pump, vaporizer, CNG storage, and a CNG dispenser. The station was manufactured by NorthStar, Inc. of Evanston, Wyoming. Please see photographs in Attachment 1 and Facility Diagram.

c. Objectives

The Contractor must meet the following objectives:

Maintain GRCA’s LNG/LCNG station in a safe manner that allows NPS operations, including the park’s visitor transportation system, to continue operations without interruption.

Perform preventative and periodic maintenance and required inspections so that all components of GRCA’s LNG/LCNG station are maintained in good working order and in accordance with all applicable municipal, county, state and federal regulations, codes, laws, ordinances, standards, rules, supplements and industry standards in force during the period of the contract.

Install new, updated weights and measures certified CNG dispensers that are fully compatible with the existing LNG/LCNG station configuration and meet all applicable laws, guidelines, regulations, codes and industry standards.

Perform a comprehensive condition assessment of the LNG/LCNG station to ensure it is in compliance with all applicable laws, regulations, codes and industry standards.

Perform non-emergency and emergency repair work to ensure that the LNG/LCNG station operates safely and effectively and in compliance with all applicable laws, regulations, codes and industry standards. This includes ordering and ensuring timely delivery of any necessary parts.

Provide for on-call emergency response with a qualified technician available by phone 24 hours a day 365 days a year and with a qualified technician on site within 24 hours of initial on-site request.

Provide accurate and comprehensive reports and invoices in a timely manner.

They are Angi MCDS-2 dispensers that dispense approximately four gallons per minute. Each dispenser has two nozzles – one is 3,000 pounds per square inch (psi) and the other is 3,600 psi. All bus fueling is currently done with the two 3,600 psi nozzles. Please see photos in

Attachment 2 for more details on the existing dispensers.

The Contractor must safely install new, updated CNG dispensers that are fully compatible with the existing LNG/LCNG station configuration and meet all applicable laws, guidelines, regulations, codes and industry standards. Each dispenser must have two nozzles for a total of four nozzles capable of dispensing CNG. Three nozzles must be able to dispense at least four gallons per minute at a minimum of 3,600 psi. The fourth nozzle must dispense at a minimum of

3,000 psi.

In addition to the dispensers being weights and measures certified, a card reader system and all associated software must be installed and implemented that can allow for third-party billing for concessioner-operated buses and vehicles.

The NPS will determine when the Contractor will perform this work, at a time when there is the least amount of disruption to fueling operations. The park’s transit buses and concessioner-operated buses and vehicles operate year round and will need to fuel while the dispensers are being replaced.

The Contractor must perform this installation in a manner to ensure that the LNG/LCNG station operates safely and effectively and in compliance with all applicable laws, guidelines, regulations, codes and industry standards.
