Subject: RE: Tustin Ranch, CA - Costco Fuel Facility - CalEEMod request (BCE14640)
Hi Sean,
We have completed the CalEEMod runs and the results for the criteria pollutants (construction and project) as well as GHG
emissions are summarized in the three tables attached - all emissions are below the significance criteria!
CalEEMod has "Gasoline/Service Station" and "Parking Lot" as build -in choices for land uses, which were selected in our model runs.
A few notes on the assumptions that we used in our analyses to estimate construction and operational emissions:
Construction
o Assumed construction begins 7/1/19 (Note: selection of a later date would result in lower or same emissions)
a Assumed construction of the following per CaIEEMod land uses and size metrics:
■ Gasoline/Service Station, 16 pumps, Lot Acreage of 0.9216 (based on project Site Plan dated April 15, 2019).
■ Parking Lot, 9,136 sq.ft.
• Includes demolition of 9,136 sq.ft. building.
o CalEEMod defaults for all other construction parameters.
Operation
o Assumed an operational year of 2020
a For vehicle trips:
■ Used "Net New Project Trips" for PM Peak Hour in Table 2 of the traffic analysis (70) to calculate trips/pump/day
assuming 24 hour operation (conservative since Costco gas is not 24 -hr operation).
• Note, using PM Peak Hour is also conservative because it is higher than AM Peak Hour.
■ Used 100% primary trips in CaIEEMod based on Table 1 in the traffic analysis where pass -by and diverted trips were
removed to determine Total Net New Costco Trips.
• In essence this means that we have modeled 70 Net New Project Trips per hour, as indicated above, assuming
all of these trips are primary trips. No diversion or pass -by trips are included.
■ CaIEEMod defaults for other trip parameters including trip lengths.
o CaIEEMod defaults for all other operational parameters.
Let me know if you have questions. I will be at a client site all day tomorrow, but back in the office on Wednesday.
Thanks!

analysis.
2 For purposes of this analysis VOC emissions are assumed to be equal to ROG.
3 Total Area and Energy emissions were estimated using CalEEModo.
4 Total mobile emissions were estimated using CaIEEMod° default trip lengths and emission factors with Project -

Notes:
1 One-time emissions (i.e., construction) and operational emissions were calculated using
CalEEModo.
2 Emissions are presented as CO2e, which include CO2r CH4, and N20 emissions, weighted
by their respective global warming potentials.
3 Emissions shown as zero may be non -zero values, however, they are below a
meaningful reporting level for this analysis.
4 One-time emissions from construction were amortized over a 30 -year period.
