Update programs in PLC and HMI
Check I/O between all valves, generator, switchgear.
With generator running at no load, set system to run off of 100% digester gas.
Ensure all pressure and flow requirements are met and no alarms are present during normal operation Set system to run off of highest allowable natural gas blend.
Ensure that engine sees higher methane content
Run generator at no load and ensure all pressures and flow are maintained Set system back to 100% digester gas and simulate changing digester levels.
Ensure system reacts by blending natural gas into the digester gas Ensure engine sees changing methane content of gas
Run generator to 100% load on 100% digester gas and allow Cummins to tune emissions.
Ensure all pressures and flows are maintained throughout all load levels Shut generator down, switch to highest allowable NG blend. Run generator to 100% load on NG blend and allow Cummins to tune emissions.
Blend at middle methane content value and run generator up to full load and allow Cummins to tune emissions.
Set system in automatic and allow generator to run at multiple loads with changing methane content and ensure all emissions, flow, and pressure are met.
Ensure methane content does not change more than specified amount at any point.

Clarifications
PEECO will utilize Monday & Friday as Travel Days
PEECO does not have any off hours labor included in this proposal. If any overtime hours are included, this will be billed out separately. If OT Hours are required, Cummins must get this approved by management before technician is allowed to work additional hours This proposal includes (1) Mobilization to and from the site for each week quoted. If any additional mobilizations are required, costs will be associated.
This quote assumes that all of the existing components in the PEECO Visalia switchgear equipment are in working order. If any devices are found to be inoperable or defective, PEECO can supply a separate quote to replace these parts.
If PEECO has to cancel either of these dates due to the site not being ready, cancellation fees may apply to Re- Schedule.
Additional labor to the three weeks standard commissioning time will be charged separately at a $6,600 daily rate.

Miratech to perform Commissioning for the exhaust gas aftertreatment at City of Visalia (CA), up to three weeks (MON – FRI, travel time included).
Equipment purchase PO2312 from 8/13/2019 included one week of commissioning and start up to be executed in 2020.
Test and startup all sensors, urea injection, air pressure and air injection. Ensure all electrically operated valves and pumps work correctly and all sensors are reading accurately. Replace any non-functioning components as necessary.
Test all I/O with the generator and switchgear and ensure that each side is receiving the proper signals and load levels.
After engine has been run for 4 hours at full load for break in, let exhaust components cool sufficiently to allow access for work.
Open SCR housing and load SCR bricks with sealing material.
Close SCR housing and seal with gasket.
Start and operate generator at full load until sufficient catalyst temperature is achieved.
Start injection and begin setting up the load/injection table. Fine tune injection until proper emissions reduction is achieved.
Reduce load in 10% steps and tune the load table as necessary to achieve proper emissions reduction. Continue until all load steps are tuned down to customer specified level, usually 50% load.
Save all changes to all tables and operating parameters.
Test all warning and shutdown points and fine tune warning and shutdown levels. Ensure that the warnings and shutdowns annunciate properly on the SCR HMI screen and send proper signals to the generator or switchgear for warning or shutdown of the generator. During these tests, SCR injection may be stopped temporarily to cause faults to appear.
Operate generator in automatic mode and log to ensure proper operation.
