Introduction
Clean Energy has worked with the City of Santa Clarita (City) for more than two decades, starting with construction of your transit CNG fuel station (see photo below) and by continuously providing reliable maintenance of all your CNG fuel stations to the present. We are intimately familiar with all the fuel station equipment within the scope of this contract, and have the processes, knowledge and software and hardware tools in place to seamlessly continue our service on July 1 if awarded. Having a reliable contractor is more important now than ever before, as your compressors and equipment at the transit CNG fuel station are nearly 20 years old and have a significant number of run hours.

Our proposal includes pricing for the full scope of requested service. Where possible we have simplified the pricing structure for the City’s convenience and benefit. We are also familiar with the structure of this contract and the City’s terms and conditions, and do not foresee any challenges to quickly signing a new contract if awarded.

Work Plan and Scope of Work
I. Seamless Project Kickoff
Clean Energy is very familiar with your properties, as well as the history and current condition of the fuel station equipment. Thus, we do not need to perform an equipment survey, perform initial baseline inspections or review maintenance records, as we would do if taking over service at a new customer’s property. We also already have our remote monitoring SCADA hardware and systems installed. The start of our new contract term would be seamless.

If awarded, we would recommend organizing an in-person meeting at your facility, including the City’s operations and facilities team and our operations team, to discuss our performance on the current contract and your expectations of us for the new contract term. We reserve the right to negotiate mutually agreeable terms after award.

II. Weekly Inspections
Our technicians will be onsite weekly to perform routine inspections on your compressors, dryer, dispensers, and other equipment at the Transit and Public Works properties (City Hall requires quarterly inspections). The purpose is to identify potential future issues, excessive wear, or deviations from normal trends for the equipment’s expected performance. Please see Appendix A for sample maintenance plans.

Preventative Maintenance
The required major PM intervals for the City’s Ariel (ANGI) compressors are at 4000, 8000, 16000, 20000, 24000, 28000 and 32000 run hours. In between those hours there are additional minor PMs. Clean Energy has all required tasks for each PM fully

documented in equipment manuals and periodic
update bulletins from the OEM. All of this information
is loaded into our Field Service computerized
maintenance system.

The image on right is a snapshot from one page in
our Field Service system for one of your
compressors at the Transit fuel station, stating the
timing of the next expected PM for this unit. This is
one of many tools used by our planners to ensure we
effectively plan for and execute PM work at all sites
we maintain. Generally, our competitors do not
use a system such as this to effectively plan and
manage preventative maintenance tasks.

III. Quality Control / Budget and Schedule
Control
Service Quality Monitoring Program
The quality of our operation and maintenance
service is ensured by the depth of experience of our
technicians, and by our clear processes for detailed
documentation of services performed. Any time work
is performed at your sites our technicians note what
has been done in our Field Service software using
their tablets. Our work orders go through two levels
of review to ensure accuracy and the
appropriateness of work performed. Our supervisors,
managers, and directors make regular quality
inspections of our worksites to ensure equipment
performs to the proper standards our customers expect. Any quality issues discovered are immediately resolved and require next-level approval when complete. The entire service team also focuses on consistent communications (prior, during, and post-work) as well as regular quarterly meetings with customers to ensure expectations are met or exceeded.

Schedule Control
Clean Energy manages scheduling by assigning service technicians to perform regular maintenance at the City’s stations. At all hours of the day and night, Clean Energy technicians are working. Critical after-hour service does not require Clean Energy to dispatch an on-call employee from their home as we have technicians assigned to work all three shifts 24/7/365.

Schedules for preventative maintenance are managed by our operations team at our Newport Beach headquarters. They ensure that correct parts are in stock and properly trained technicians are available to perform PM tasks at OEM recommended intervals.

Budget Control
Our proposed prices are based on a review of your maintenance records and most importantly our direct experience with operation and maintenance of the City’s CNG stations. We know what it takes to maintain a high quality staff of technicians, support personnel and spare parts inventory, as well as all the ancillary systems and technologies to make it all work effectively together. Additionally, our strong financial position and our stable, long-term local presence will minimize the risk the City could face of another contractor not being able to effectively maintain your station for the life of the contract.

Compliance to Contract Requirements and Technical Specifications Clean Energy employs a simple operation and maintenance philosophy, which is to protect customer fueling. We prioritize the reliability and safety of your CNG fueling equipment to ensure the City’s buses will make rollout each day. We do this by focusing on preventative and corrective maintenance, and by investing in our people, training, processes, and technology. The following sections describe in greater detail how we accomplish this, and the positive results including world-class station reliability and performance.

We understand the best way to ensure station reliability is with a proactive and regularly scheduled maintenance plan (sample in Appendix A). However, with heavy machinery and equipment operating at high horsepower, pressures, and temperatures, as well as hundreds of moving parts that are subject to vibration plus the station electronics, unscheduled maintenance will inevitably happen. Clean Energy is fully prepared for any contingency because of our local staff, training, and internal processes.

Any of the following will trigger a Clean Energy response to an issue at the City’s CNG stations:
 Fault detected by our 24/7/365 live station remote monitoring software, monitored by our 24/7 Command Center
 An email message sent to our 24/7/365 Command Center and field staff from our local PLC hardware, triggered by a station alert or fault  Our 24/7/365 Command Center receiving an alert or fault from our server-based SCADA system
 RTC reporting a station performance or safety issue by calling our 24/7/365 Command Center at (866) 278-3674 or sending an email to [email protected] or notifying our onsite technician.

The scenarios outlined above trigger the following response:
 Clean Energy Command Center staff will review the fault or situation and try to rectify the problem remotely. If they are unable to resolve the issue, a technician or supervisor is notified and dispatched.
 A Clean Energy technician will respond using our best commercial efforts to complete repairs. At all hours of the day and night, local Clean Energy technicians are working. Critical after-hour service does not require Clean Energy to dispatch an on-call employee from their home as we have technicians assigned to work all three shifts.
 Clean Energy has Field Operations Supervisors on duty 24/7/365 to support our technicians and assist as needed, for example when a situation is escalated to their level.

City of Santa Clarita

Once the issue is corrected, the City’s staff will be given a full debrief, including the corrective measures taken to address the problem. In addition, Clean Energy documents service activities using our Field Service software. The City will receive access to our online web portal, where you will have access to monthly reports that document all service activities at each of your stations. A sample of one of these reports – our Customer Site Report – is provided in Appendix B.

Emergency Preparedness
Though rarely needed, Clean Energy is prepared for disasters and emergency events.

When a disaster or emergency occurs, Clean Energy’s technician team follows our proprietary, formal Emergency Preparedness and Response Plan that includes how to prepare and react to emergencies or natural disasters. Safely operating through emergency conditions is critical and we have trained our staff how to implement our emergency plans. During emergencies, our staff communicate in real time on the status and ability to fuel at your station. Our plan is outlined in our Health and Safety Manual, which is readily available to all Clean Energy employees.

If one of the City’s CNG fuel stations loses power from the electric grid, the onsite standby generator will be used to run the station and fuel your fleet. If another issue causes your generator and/or station to otherwise be unavailable due to an emergency, such as a natural disaster, Clean Energy has public access CNG stations in the general area for your use.

Clean Energy’s Command Center. Live 24/7/365 operators respond to customer calls. This team is responsible for communicating with customers, dispatching technicians, and documenting the resolution steps taken for each call.

Spare Parts Plan
We procure the parts we determine are long
lead items or critical to station operation.

Additionally, we have over $12 million of spare
parts in our current inventory. The scheduled
and emergency repair parts strategy for the City
consists of stocking critical parts and
consumables in our service vehicles and locally
at your facilities. Other parts are stored at our
regional and national warehouses. Our national
warehouse is in Carson, CA. Our Command
Center operators can view our inventory of
spare parts (including those on our technician’s
vehicles) to determine if technicians have the
correct parts for each job or if they are available
at one of our warehouses.

Maintenance Program Tools
Clean Energy uses the following tools to support our work plan. Many of these tools are unique to Clean Energy and differentiate our service from that of our competitors.

Command Center. Our Command Center, located in Newport Beach, CA is staffed by 20 Clean Energy employees for 24/7/365 coverage to monitor real time station status and respond to any station alert or fault that occur.

Once a fault is detected, our Command Center staff will immediately evaluate the situation and determine the appropriate response.

Remote SCADA. Our Command Center has access to screens that show the real time status of your stations. The screens are customized to match the equipment and automation hardware installed at your locations. We can remotely reset faults from the SCADA screens when appropriate.

Historian. Clean Energy uses technology to collect and record data that we use to make station adjustments and improvements, analyze station performance, and assist in diagnosing station faults. This product records critical station data including pressures, temperatures, valve status, and many other conditions.

The data collected is used to make improvements in station software, optimize set points, and help diagnose station issues. The long-term goal is to use this data to Carson Parts Warehouse. When a technician uses
a spare part from your station, our warehouse inventory system automatically generates a parts replenishment
order.

minimize station outages by predicting future component failures and correcting them before they fail.

Field Service Software. We use Microsoft Field Service software to manage assets and maintenance services. This software is used to manage tasks such as:
 Scheduled inspections and proactive maintenance
 Workforce task scheduling
 Document and organize all maintenance activities including scheduled and corrective maintenance activities
 Track status of OEM recommended maintenance plans for all tracked assets These electronic tools give our employees accurate, real-time maintenance records for every Clean Energy-maintained station.

Reporting Plan
The basis of our reporting plan is our cloud-based Field Service and Historian software, which will capture all relevant information about your station and is described above in the section Maintenance Program Tools. The City has access to reports as described below.

Customer Online Portal Access. We have a
secure, online customer portal which allows the
City staff to view and download monthly reports,
invoices, and monitor work that is currently
scheduled and has been completed at your
stations. Your staff currently has access to this
tool.

Customer Site Reports. Clean Energy provides
monthly Customer Site Reports to all our service
customers. Customer feedback indicates that
these reports provide great value, because they
provide a clear history of service activities and
issue corrections at their respective CNG stations.

The reports detail work order numbers, dates and
parts that have been installed, and who (which
technician) performed the work. They also
categorize activities as inspections, preventative
maintenance, and correctives. This level of transparency and detail is not provided by Customer Online Portal – Dashboard
View (Example). The City’s staff may view
site specific information such as current and
future scheduled work, monthly reports, and
invoices.
