INNOVATING CLEAN FUEL SOLUTIONS: CHEVRON/WAYNE PERRY’S CNG FUELING SYSTEM IN SANTA MARIA
December 20th, 2024
The Chevron station located at 1155 E Betteravia Road, Santa Maria site, is the newest project where innovation meets sustainability with the recent installation of a cutting-edge Compressed Natural Gas (CNG) fueling system. This project lead by Wayne Perry, Inc. and engineered and permitted by Fiedler Group highlights the commitment to advancing clean energy solutions and providing infrastructure to support heavy-duty vehicles (HDVs).
TRANSFORMING THE SITE WITH ADVANCED INFRASTRUCTURE
Wayne Perry completed site construction services on September 30, 2024, introducing several transformative elements that enhanced the site’s functionality and sustainability. The installation featured a high-tech compression system comprising advanced compressors, a cascade storage system, and a matrix panel to ensure efficient fuel delivery. Accessibility and functionality were improved with the addition of two CNG dispensers, strategically placed on extensions of the existing HDV fueling islands. A purpose-built CNG compound was created to house all critical compression components, while a new natural gas supply line was installed to guarantee a consistent and reliable gas supply. Additionally, the site’s landscaping was restored and enhanced, seamlessly blending environmental stewardship with compliance to the historical conditions of approval.
OVERCOMING UNIQUE CHALLENGES
Projects often encounter hurdles and challenges, and this one was no exception. However, the challenges presented opportunities to innovate and adapt. One significant challenge was the restoration of historical landscaping, as the property’s original 1964 conditions of approval required creative design and sourcing solutions. Fiedler Group addressed this by developing a landscaping plan that successfully balanced historical accuracy with modern sustainability. Additionally, routing the CNG supply lines proved difficult due to the presence of existing underground storage tanks (USTs) and other infrastructure. This challenge was overcome with innovative routing techniques that enabled seamless integration without compromising functionality.
FIEDLER GROUP’S EXPERTISE IN ACTION
Fiedler Group supported this important project by providing comprehensive services including:
- Preliminary Design and Feasibility Studies: Careful planning established a solid foundation for the project.
- Entitlement Services: Ensuring all regulatory approvals and compliance requirements were met.
- Site Design: Expert regrading and landscaping addressed functional and aesthetic needs.
- Permitting Services: Smooth navigation of permit processes kept the project on schedule.
PAVING THE WAY FOR A CLEANER FUTURE
The newly installed CNG fueling system not only supports operational needs but also serves as a beacon of sustainable innovation. By accommodating cleaner fuel technologies for HDVs, Chevron is setting an example for the energy sector.
This project also exemplifies Fiedler Group’s ability to deliver complex projects that blend technical precision, environmental stewardship, and creative problem-solving. As we continue to partner on groundbreaking initiatives, we remain dedicated to driving progress and exceeding client expectations.
Stay tuned for more insights into our work and how we’re shaping the future of energy infrastructure.

Clean Energy Fuels Corp. Expands LNG Production Capacity to Meet Growing Demand
June 18th, 2024
As the largest provider of natural gas fuel for the transportation market in North America, Clean Energy Fuels Corp (Clean Energy) has successfully completed the construction of a third production train at its liquefied natural gas (LNG) plant in Boron, California. This expansion increases the plant’s volume capacity by 50 percent, solidifying its position as the largest facility of its kind in the Southwest U.S. The Boron plant can now produce up to 270,000 gallons of cleaner-burning LNG daily, meeting the rising demand for bulk LNG from a diverse range of customers including city buses and large container ships.
Fueling with LNG offers substantial environmental benefits, particularly in port areas that frequently suffer from severe air pollution. LNG-powered ships significantly improve air quality by surpassing the International Maritime Organization’s (IMO) 2030 standards for ocean vessels, achieving zero sulfur emissions.
Pasha Hawaii, a Clean Energy customer applying LNG in the maritime shipping industry, now operates three LNG-powered container ships from the Ports of Long Beach, Oakland, and Honolulu reaching an impressive requirement of 2,115,726 gallons in April 2024 . Since the commissioning of Pasha Hawaii’s first LNG-powered ship in August 2022, Pasha Hawaii’s LNG ships have achieved a 90 percent reduction in nitrogen oxide and a 25 percent reduction in carbon dioxide compared to traditional fuel-powered vessels.
“Pasha Hawaii’s leadership in sustainable shipping has grown with the commissioning of their third LNG-powered ship. By expanding their LNG fleet, they are not only reducing pollution and carbon emissions around the ports but also demonstrating that LNG can be as effective as traditional fuel oil,” said Greg Roche, Vice President at Clean Energy. “The increased LNG production at our Boron facility will enable other customers to decarbonize their operations.” Fiedler Group applauds Clean Energy’s commitment to supporting the transition to cleaner energy sources, helping to mitigate environmental impacts and promote sustainability across all avenues of transportation.

Expanding Fueling Horizons: SC Fuels Introduces New Cardlock Facility in California
June 13th, 2024
SC Fuels recently announced the addition of a new fueling facility providing unrestricted access to private and the public heavy duty vehicle operators, trucks and passenger vehicles. This facility situated at the Irwindale Gateway, 1200 Arrow Highway, southeast corner of Arrow Highway and Live Oak Avenue in the City of Irwindale, is set to become a critical resource for the transportation industry in the region by offering an extensive selection of fuels, including: Diesel, Biodiesel, Red diesel, E-85 Gasoline. Fiedler Group is a proud member of the team that brought this project to completion.
State-of-the-Art Infrastructure
The scope of work for the new Cardlock facility included significant construction and infrastructure developments:
• Fueling Canopy: One new 129’-0” X 42’-0” canopy sheltering 14 dispensers, features a combination of multi-product and single-product options, as well as five DEF (Diesel Exhaust Fluid) dispensers.
• CMU Enclosure: One 42’-0” X 23’-4” concrete masonry unit (CMU) enclosure, equipped with metal screening gates, houses an electrical equipment control room, aboveground storage tanks, and a trash enclosure area.
• Underground Storage Tanks: The installation of underground storage tanks to ensure a reliable and efficient fuel supply.
• Additional Site Improvements: Various landscape, drainage, and site improvements were implemented to enhance the functionality and aesthetics of the facility.
Overcoming Challenges
The development of this facility was not without its challenges. Notably, two significant hurdles were successfully overcome by Fiedler Group in helping to deliver this project:
Redesigning the Equipment Enclosure: During the construction process, a Southern California Edison (SCE) guy wire was discovered within the proposed footprint of the equipment enclosure area. This unexpected obstacle required a complete redesign of the enclosure to accommodate the existing infrastructure without compromising the facility’s functionality.
Planning Approval: Securing planning approval for the redesigned enclosure area presented its own set of challenges. The project team had to navigate complex regulations and ensure that all required setbacks were met. Through diligent planning and collaboration with local authorities, the necessary approvals were obtained, allowing the project to proceed without significant delays.
Looking Ahead
With the opening of this new public access Cardlock Fueling facility, SC Fuels continues to demonstrate its commitment to providing reliable, accessible, and innovative fueling solutions across California. This site not only exemplifies the convenience and efficiency of truck fueling SC Fuels is known for but also underscores SC Fuels’ dedication to overcoming challenges and delivering exceptional service to its customers.
