Appendix A: Palm Desert Greenhouse Gas Inventory 2013 Methodology
Disclaimer
Statewide greenhouse gas modeling software and reporting methods have been
updated since the preparation of the 2008 Greenhouse Gas Inventory. The 2013
Greenhouse Comas Inventory update was prepared using the ClearPath California online
reporting platform made available through the California Statewide Energy Efficiency
Collaborative Program (SEEC). The ClearPath planning toot improves upon the Clean
Air and Climate Protection (CAP) software - the previous industry stndard for tracking
local carbon emissions - by increasing accuracy and thoroughness of GHG inventory
reporting,
Changes in the reporting software resulted in variations of emission factor sets and CO2E
intensities that effect overall C FIG emission totals. For example, 1,000 kWh of electricity
consumed in 2003 emitted " " tonnes Of CO2E according to ACP; however 1,000 kWh
ofelectricity consumed in 2013 may emit "Y" tonnes of CO2E according to Cle arPath,
GHG reporting is relatively new and constantly being'advanced due to expanding
research and innovations in technology. Therefore,; subtle changes in reporting
methods and GHG intensity factors are expected and necessary for reporting GHG
data that represent current understanding of the field.
In addition, the 2010 U.S. Census;update resulted in miner differences in population and
housing ; data that may - affect future GHG projections and assumed per capita
consumption, However Census data and forecasts are subject to inherent uncertainty
and variations in accuracy over time are expected.
The 2013 methodology, reporting process, and variations in GHG factor sets are further
discussed in Appendix A: Palm Desert Greenhouse Gas Inventory 2013 Methodology.

Municipal i i
In 2013, municipal; facilities and activities emitted 9,800'metric tonnes Of CCU ,
representing a 9 decrease (978 MT of CO2E) from 2008, Municipal facilities accounted
for 16.0%, streetlights & traffic signals for 6.9%, water delivery for 25.0%, wastewater for
23.2%, the municipal fleet for 16.5` , the employee commute for 2.4%, transit fleet for
9.3%, and refrigerants from all sectors account for 0.7% of municipal emissions.

Palm Desert municipal buildings and facilities contributed 1,562 metric tonnes of C:0 E,
representing 16 of total municipal greenhouse gas emissions. Of this, electricity
accounted for 1,398 tonnes (14% of municipal emissions), and natural gas accounted
for 164 tonnes (2% of municipal emissions).
Southern California Edison (SCE) provides electricity to most of the City of Palm Desert.
The Imperial Irrigation District (11 ) provides electricity to a small portion of the City south
of Interstate-10 and east of Cook Street. SCE and IID provided electricity usage reports
for all municipal accounts for year 2013.
The Southern California :gas Company (CG) provides natural gas supplies and services
to the City. SCE tabulated total natural gas consumption for municipal buildings for
year 2013,

Compared to data provided in the 2008 Palm Desert GHG inventory, municipal
buildings and facilities consumed 3,439,795 kWh(237r) more electricity in 2013 than in
2008. This dramatic increase is largely due to differences in data reporting and the
acquisition and construction of new municipal facilities after
2008, as described below.
In reality, the same buildings reported in 2008 consumed
424,774 kWH less in 2013
demonstrating an overall increase in efficiency and/or conservation.

As shown in the table above, the 2008 GHG Inventory included electricity consumption
data for 9 municipal buildings/facilities and 8 ether "unidentified" lowconsumption
locations; electricity consumed by them totaled 1,446,822 kWh. In 2013, those particular
facilities used 1,022048 kWh of electricity, which represents a'decrease of 424,774 kWh
(29%) compared to 2008.
In 2013 an additional 3,864,569 kWh of electricity were consumed by municipal
accounts that were not reported in 2008. Approximately 47 (1,817,046 kWh) of this
electricity was consumed by 4 pumps associated with the Desert Willow Golf Resort,
These pumps were acquired and upgraded by the City after 2008.1 Approximately 33%
(1,270,60 kWh) was consumed at the Desert Willow Golf Resort clubhouse. The
clubhouse was built prior to 2008; however, the 208 GHG Inventory omitted it.
Approximately 1 % (495,171 kWh) of the electricity was consumed by the Palm Desert
Aquatic Center which was built after the 2008 GHG 'Inventory (in 2011). Additional
electricity was consumed by the Chamber of Commerce, Palm Desert Gulf Academy,
fire stations, and miscellaneous small consumer accounts, which include park retrooms,
outdoor pedestal pales, and irrigation devices.
In addition, the Palm Desert Golf Academy and Town Center Way' Fire Station were in
operation prior to 2008, however they were not accounted for in the 2008 Inventory.
Natural Gas
In 2013, municipal buildings and facilities consumed 30822 therms, Compared to data
provided in the 2008 GHG Inventory, this represents a decrease of 101,182 therms (77` )
from 2008. The difference is due to overstating 2008 natural gas usage rather than a
significant decrease in usage, as described below. A comparison of natural gas data
reported in 2008 and 2013 is provided in the following table.;

s shown above, the 2008 GHG Inventory concluded that municipal buildings/facilif ies
consumed 132,004 therms of natural gas in 2008. However, recent consultation with
SCG indicates this overstated actual natural gas usage because it included
"residential" accounts.2
SCG staff reviewed the 2008 data and found that "residential" accounts do not exist for
municipal buildings, and such data should not have been included in the 2008 GHG
Inventory. SCG also reported that it dues not disclose account information for City -
owned apartment buildings because tenants pay natural etas bills, not the City, and
such accounts are not considered municipal accounts,
To provide an accurate comparison of natural gas consumption at municipal buildings
between 2008 and 2013, "residential" accounts should be removed from the 2008 total
shown in the table above. The resulting comparison shows that 2013 consumption
increased by 2,750 therms f 10 i compared to 2008.
Increases were most notable t: 1) the Henderson Community Building, which opened
after 2008 to include offices of the Chamber of Commerce and other community
groups, and 2) Visitors Center building on Highway 111, which now houses the Palm
Springs Art Museum in Palm Desert (opened in 2012). Notable decreases occurred at
the Public Works Corporate Yard, which eliminated d compressed natural gas iCNGi
fueling station after 2008.3
Streetlights and Outdoor Lighting, and Traffic Signals
Streetlights, outdoor fighting, and traffic signals contributed 672 tonnes of CO2e,
representing 6.9 of the municipal greenhouse gas emissions. The Electricity Municipal
Accounts Reports for 2013 provided by Southern California Edison and Imperial Irrigation
District ; give the electricity usage for Traffic Signals, = Streetfights, Park Lighting and
Outdoor Lighting.

Water Delivery
The energy associated with water pumping contributed 2,445 tonnes of CO2E,
representing 25% of municipal greenhouse gas emissions. Water for Palm Desert is
provided by the Coachella Valley Water District. The District serves a valley population
304,701 (2013); this inventory accounts only for the proportion serving Palm Desert. For
the purposes of this inventory, emissions from the pumping energy (electricity) of the
water used within the city Limits are included.

Wastewater Treatment
The energy associated with wastewater treatment contributed 2,274 tonnes of CO2E,
representing 23.2% of municipal greenhouse gas emissions. The Coachella Valley Water
District provides wastewater services to the following cities- Palm Desert, Indian Wells,
Rancho Mirage, and Cathedral City. Wastewater from Palm Desert is transmitted
through sewer lines to the Cook Street treatment plant (Water Reclamation Plant 10),
operated by means of an --"aerobic',. treatment" or --"activated sludge" system. Palen
Desert contributes approximately 50% of the wastewater to the plant. Emissions from
electricity pumping and treatment of wastewater are the largest source of emissions
from the wastewater process.

Municipal Fleet
In 2013, the municipal fleet contributed 1,615 tonnes of CO2e, representing 16.5% of the
municipal greenhouse gas emissions. The City of Palm Desert's municipal fleet is
comprised of vehicles from Administration, Council, Parks, Police, Streets, City Yard and
Visitor's Center. Unlike the 2008 inventory, 2013 total vehicle miles traveled (VMT) and
consumption per specific vehicle type could not be provided. However it was assumed
that the majority of gasoline -fueled vehicles were passenger vehicles and the majority
of diesel -fueled vehicles were light -medium heavy trucks.

Employee Commute
Greenhouse gases are emitted by the consumption of fuel as City employees commute
to and from work. In 2013, employee commutes contributed 244 tonnes Of CO2E, which
represents 2.4% of total municipal emissions.
The number of annual vehicle miles traveled byemployees was estimaied using the
same formula and assumptions used in the 2008 Palm Desert GHG Inventory: the
number of employees was multiplied by miles per round trip and number of annual Mips.
There were 1] 6 City employees in 2013, and they worked 249 business days during the
year (excludes weekends and the City's 12 observed holidays). The analysis assumed
707o of employees traveled in passenger cars and 30% traveled in light duty trucks. If
also assumed 60% of employees traveled 25 miles round trip, 30% traveled 15 miles
round trip, and 10% traveled 5 miles round trip to and from work.

From 2008 to 2013, the number of vehicle miles traveled decreased by 268,920 miles or
32%, and CO2E emissions decreased by 202 tonnes or 45%. The some formula and
assumptions were used to calculate 2008 and 2013 emissions, and the only variables
were the number of municipal employees and a marginal increase in vehicle fuel
efficiencies, Therefore, the decrease is a direct result of a 32% reduction in the number
of municipal employees, from 170 employees in 2008 to 116 employees in 2013.

Transit Fleet
SunLine Transit Agency provides transit bus service in the Coachella Valley, including
the City of Palm Desert. In 2013, the transit fleet contributed an estimated 921 fonnes of
CO2E, or 9.3` of total municipal emissions, from fuel consumption in the City.
In 2013 five ;(5) fixed bus routes traversed the City. Because they extended into
neighboring communities, Goggle Earth and SunLine route maps were used to
calculate only the route mileage within the City limits. Additional mileage was added to
account for trips to and from transit stations each day. For each of the 5 routes, +SunLine
staff provided the number of bus trips traveled per day. Total annual vehicle miles
traveled within the City limits were estimated at 361,867 miles.
ADA paratransit buses and SunLine support vehicles were not included in this analysis
because they do not use fixed routes and their activity levels fluctuate.
All buses serving the City use compressed natural gas (CNG). SunLine reported that the
average CNG bus gets 2.8 miles per 126.67 cubic feet of CNG. This resulted in estimated
emissions of 921 fonnes of CO2E in 2013.

From 2008 to 2013, greenhouse gas emissions generated by the transit fleet decreased
by 205 tonnes of CO2E, or 18` . The decrease is likely the result of differences in data
availability and assumptions used in the 2008 and 2013 analyses. The 2008 analysis relied
on bus route schedules to estimate the number of bus trips traveled along each route
per day; whereas the 2013 analysis obtained route -specific data from SunLine staff. The
2008 analysis used CNG fuel efficiency assumptions from an online source; and the 2013
analysis used fuel efficiency data provided by SunLine. There are also differences in the
number of bus routes traversing the City, bus routes, times of operation, and mileages
between 2008 and 2013.
Fugitive is i ns for All Sectors
Fugitive emissions include refrigerants used within the City limits, including those used by
Desert Sands Unified School District (DSUSD), the Riverside County Fire Department, and
commercial facilities in the community. In 2013, fugitive emissions contributed 67 tonnes
Of CO2E, which is 0.7% of total municipal emissions
DSUSD
The Desert Sands Unified School District fleet is comprised of 252 busses and
support vehicles. For these 252 vehicles, 367.92 pounds of R-1 a (HFC®134a)
refrigerant are used annually. Based on student population, 82.19 pounds of
DSUSD refrigerants are attributed to Palm Desert,
10
Since 2008 DSUSD has increased its fleet by 57 vehicles~ therefore increasing
refrigerant use by 21.65 pounds.
Fire D art~ ent
Riverside County Fire Department reported seven of the eight Fire Vehicles used
three pounds of` -134a refrigerant additions in 2013, bringing the total' of
refrigerants used by the Riverside County Fire Department in Palm Desert to 21
pounds.
This represents a 6-pound increase from 2008 and is attributed to the addition of
new fire vehicles reported in 2013.

Refrigerants are also used by commercial facilities in the community. The South Coast
Air Quality Management District's (S `AQMD) Rule 1415 strives to reduce emissions of
high global warming potential refrigerants from non-residential, stationary ;air
conditioning systems that "hold more than 50 pounds of high global warming potential
refrigerant and provide cooling to spaces to an intended temperature of not less than
680F for the purpose of cooling objects or occupants." Rule 1415 requires submittal of a
Registration Form that discloses types, and quantities of refrigerants stored and added.
In 2013 only two (2) commercial entities in Palm Desert submitted Rule 1415 Registration
Farms. They had a combined refrigerant storage capacity of 494 pounds, the majority
of which (96.8 ) was R-22, a greenhouse gas that has been mostly phased out in new
equipment. The remaining 3.2 was R-410A> which is often used as a replacement for R-
. Neither facility repartee additions of refrigerants to their equipment.

Commercial
Consistent with the methodology used in the 2008 GHG Inventory, the community
commercial sector includes all commercial accounts, except resorts and golf courses,
which are included in their own category, In 2013, the community commercial sector
generated 114,863 tonnes Of CO2E, which represents 19% of total community -wide
greenhouse gas emissions. Of this, electricity accounted for 93,779 tonnes (82%), and
natural gas accounted for 21,084 tonnes (18%).

Electricity
Compared to 2008 figures, 2013 electricity consumption by commercial facilities
increased by 51,922,410 kWh (21 %). This can be attributed to natural growth in the City,
particularly in that portion of the City served by IID. In 2008, IID reported consumption of
19,768,144 kWh by commercial facilities. In 2013, commercial consumption in IID`s
service area increased to 25,845,759 kWh, which represents an increase of 6077,61`5
kWh, or 31 %
Notural,Gas
A comparison of 2008 and 2013 natural gas consumption figures for commercial
facilities shows that consumption was 777,084 therms (24`) higher in 2013. This is
comparable to the 21 % increase in electricity consumption described above,
Resorts and Golf Courses
In 2013, resorts and gulf courses generated 36,093 tonnes of CO2E, which represents
6.0% of total community -wide greenhouse gas emissions. Of this, electricity accounted
for 28,254 tonnes (78%), natural gas accounted for 6,480 tonnes (18` ), and nitrous oxide
accounted for 1,359 tonnes (4).
The methodology used to estimate 2008 emissions from resorts and golf courses was also
used for the 2013 analysis. Natural gas data from Southern California Gas Company
(SC:G) provided NAILS codes that indicated which natural gas accounts were
associated with resorts (hotels and motels) and golf courses. The percentage of natural
gas consumed by resorts and golf courses was also applied to electricity records to
estimate electricity consumption by resorts and golf courses. Fugitive emissions, namely
nitrous oxide from fertilizers applied to the golf courses, were calculated using the same
methodology as 2008 (See Section 20 of Appendix A, "Nitrous Oxide from Fertilizers can
Golf Courses").

Electric
Compared to 2008, electricity consumed by resorts and golf courses decreased by
74,696,039 kWh (4 ), This is primarily due to the elimination of several hotel/motel
facility; accounts between 2008 and 2013. Several "casinos" and "bed and breakfast
inns" accounts were listed in 2008, however, according to the City of Palma Desert, there
are no such uses in the City and inclusion of those accounts in the 2008 inventory were
done so in error'.
In addition, there was a change in ownership of 4 pumps; at the Desert Willow Golf
Resort. After 2008, the; pumps were removed from the commercial sector and
transferred to the City (municipal sector); they consumed 1,817,046 kWh in 2013 (see
Municipal Buildings/Facilities discussion of this Inventory),
Natural Gas
Natural gas consumption by resorts and golf courses in 2013 was 1,035,893 3 therms (46` )
less than in 2008. This is comparable to the reduction in electricity consumption
described above,
Nitrous Oxide
It was assumed that gulf course acreage within the city had not chanced, and
therefore the amount of fertilizers applied remained the same. However, there was a
3.8% reduction in C 02E emissions that is attributed to differences of emission factors
programed into the GHC. modeling software used in 2008 versus 2013.
Tronsportafion
The community transportation sector contributed 229,722 tonnes of C 02e, representing
37% of the community greenhouse gas emissions. Palm Desert's transportation data was
developed using information provided by the California Air Resources Board (GARB)
specific to the Salton Sea air basin region of Riverside County for the year 20135
Palm [desert accounts for approximately 13` of the Salton Sea air basin's population,
This percentage of the total vehicle miles traveled in the Salton Sea air basin' of
Riverside County was attributed to Pala Desert.
Using the same methodology in the 2008 Inventory, vehicle miles traveled on Interstate
10 (heavy duty vehicles of +33,00 lbs) were not factored into the 2013 inventory
because the Interstate falls outside of the Palm Desert boundaries. In addition, this
Inventory assumes the some special' consideration for retired drivers used in 2008, It is
assumed that retired drivers ( + years) drive less than non -retired drivers. 2013
Census data shows that approximately 33 of the population in Palm Desert are 65
years old or older6. However, 307o was assumed to remain consistent with the 2008
Inventory, These assumptions reduced vehicle miles traveled by passenger cars and
light duty trucks accordingly,

The 2008 inventory reported an annual VMT of 368,694,193 and 225,083 tonnes of CO2E.
This represents a 35% increase in VMTs and only a 2` increase in CO2E emission. This
difference in emissions is attributed to increased vehicle fuel efficiency standards.
Solid't+
In 2013, community solid waste c:ontributed;61,806 tonnes of CO2e, representing 10` of
the community greenhouse gas emissions. according to the California Integrated
Waste Management Board and the City of Palm Desert, the city produced 209,375 tons
of solid waste in 2013, with 62,812 tons being transported to a managed landfill outside
of the Palm Desert boundaries and 146,563 tons being diverted. Pala Desert's diversion
rate of 0% is well above the state average.

2008 74,992 tons of solid waste 59,489 tonnes of CO2E
2013 62,812 tons of solid waste 61,806 tonnes of CO2E
Compared to 2008, this represents a decrease in overall waste by approximately 12,180
tons; however, CO2E emissions were higher by approximately 2,317 tonnes. The increase
in CO2E is likely due to changes of the modeling software and reporting process. Unlike
the 2008 Inventory, which used the C ACP software, SEEC C.>learPath analyzes waste
composition breakdowns specific to materials that contribute to greenhouse gas
emissions. The 2013 composition breakdown includes newspaper, office paper,
corrugated cardboard, magazines/third class mail, food scraps, grass, leaves,
branches, and dimensional lumber. The 2008 breakdown (CACP) is more generalized
and Includes paper, food, plant, wood/textiles, and other:
TAKING ACTION
"Business as Usual" Emissions
The projected emissions for 2020 have been updated from the 2008 inventory based on
the revised 2013 per capita emissions and population growth estimated by the Riverside
County Center for Demographic Research7. According to the study, the estimated
population for Palm Desert will grow to 52,098 in 2020 as opposed to the 2008 projection
of 64,860 by 2020. This represents a 24.5% decrease in estimated population growth
rate.
The 2013 per capita rate for GHG emissions was multiplied by the projected population
to obtain business as usual GHG emissions projections. Projecting on the current path,
emissions will raise to 640,805 metric tonnes in 2020, The 2008 Inventory projected
791,292 metric tonnes in 2020 due to higher population estimates previously assumed by
the Riverside County.

Scopes
Scope 1: Direct Emissions
Direct GHG emissions are emissions from sources within the local governments
organizational boundary that the community and local government owns or controls.
These emissions are divided into:
• Stationary combustion to produce electricity, steam, heat or power using
equipment in fixed location,
• Mobile combustion of fuels in fleet transportation sources and off -read equip enf> ;
• Process emissions from physical or chemical processing and other fuel combustion,
• Fugitive emissions from refrigerants, fire suppressants, transportation and distribution
losses and storage of fuels and other substances,
Scope 2: Indirect Emissions
Scope 2 emissions are indirect emissions from the consumption of purchased or acquired
electricity, steam, heating or cooling. Indirect GHG emissions are emissions that are
consequence of activities that take place within the organizational boundaries of the
reporting entity, but that occur at sources awned or controlled by another entity.
Scope 3 Emissions
Scope 3 emissions are emissions of potential, policy relevance to local government
operations that can be measured and reported but do not qualify as Scope t or 2. This
includes, but is not limited to, municipally generated solid waste., outsourced operations
and employee commute. Although the Protocol does not cover methodologies from
estimating Scope :3 emissions, IC;LEI and the Protocol highly encourage local governments
to measure as many Scope 3 emissions as is practical and relevant. Additional guidance
for estimating Scope 3 sources is provided by ICLEL

3. Electricity Usage
Most of the City of Palm :Desert lies within the service area of Southern California Edison
(SCE). However, a small portion south of Interstate-10 and east of Cook Street`is within the
service area of the Imperial irrigation District (IID),
The following reports were used to evaluate the City's 2013 electricity consumption.

Palm Desert jurisdictional boundaries.
2 Includes "Sill Commercial" and "Large Commercial`° rate categories.
Sun City residential accounts were subtracted from IID's Palm Desert total residential
consumption because Sun City, which is a 55+ housing development, is not within the City
of Palm Desert's jurisdictional boundary. It was assumed that the average IID residential
consumption per household for 2013 was 12,308 KWH based on 5,714 residential accounts.
Sun City has 4,985residences; therefore 61,355,380 KWH was subtracted from the IID Pal
Desert residential total (0,330 421 kWh). The updated 11D residential total was then added
to the energy assistance consumption of 1,623„426 kWh, for a total Residential total of
10,594 488 kWh.
In addition, approximately 1,211,300 square feet of commercial, retail, warehouse and
ether non-residential uses were subtracted from 10' total commercial consumption for
establishments north of 1-10 that have the 92211 zip code, however are not within the C ity's
jurisdictional boundaries. Square footages were estimated using GooCgle arth and average
electricity consumption rates were derived from the California Energy Commission's
Commercial End -Use Survey'. It should be rioted that the total square footage is
conservative and was purposely understated for analysis purposes. The approximate kWh
consumption of establishments north of the 1-10 is 11,161,259 kWh. The updated
commercial total therefore is 25,845,759 kWh.

B. Water Pumping
The data below were provided by the Coachella Valley Water District (CVWD), which is
responsible for water delivery services in Palm Desert. Domestic water wells serve a broad
area and are not restricted by jurisdictional boundaries and, therefore, it is not possible to ,
classify electricity consumption by city: The analysts uses a per capifa factor to estimate the ;
amount of electricity used to serve the Palm Desert population. The same methodology
was used in the 2008 Palm Desert GHG Inventory,

C. Wastewater Treatment
CVWD is responsible for providing wastewater treatment services to Palm Desert. The
following table describes electricity consumption by CWD"s Wastewater Treatment 'Plant
(WTP) # 10 located on Cook Street in Palm Desert in 2013. Consistent with the 2008 Pal
Desert GHG Inventory, the analysis assumes 50% of the wastewater treated at WTP #10 is
generated by Palm Desert.

D. Community -Wide Residential
To maintain consistency between the 2008 GHG Inventory and this 2013 update, the 2008
methodology was used to determine Community -Wide Residential electricity usage for
2013. SCE "domestic" and III "residential" annual usage were summed, then usage by SCE
"municipal domestic" accounts (basic electricity service for offices and maintenance at
City -owned residential buildings) was subtracted.

Note: data are taken from Total Electricity above.
E. Community -Wide Commercial
Consistent with the methodologies used in the 2008 GHG Inventory, Community -wide
Commercial electricity usage includes all remaining usage net accounted for under
Municipal Accounts, Water Pumping, Wastewater Treatment, and Community -Wide
Residential. The remaining total is 41 ,38 ,156 kWh.
SCE assigns use codes for electricity accounts; such as GS (General Service) and TOO
(Time -of -Use); however, the codes do not indicate the specific type of commercial facility,
such as restaurant hotel, bank, golf course, etc. that is consuming the electricity. Nor do HD
electricity records indicate which type of commercial facility is consuming electricity.
Therefore, as was done in the 2008 Palm Desert C.rHG Inventory, SCG's natural gas Na ICS
codes were used to determine the percentage of accounts that was resorts/golf courses
(see section E, below) versus the percentage that was all ether commercial users.
According to 2013 natural gas records, all other commercial -wide facilities consumed 76
of commercial natural gas. This percentage was applied to electricity usage; in 2013,
community -wide facilities consumed 76% of 411r; 82,156 kWh, or 312,650,4:39 kWh.

electricity accounts. Therefore, the 2013 SCG natural gas usage report was consulted, it
indicated that resorts and gulf courses accounted for 24 of community natural gas'
consumption. This percentage was used to determine electricity consumption by resorts
and golf courses. Total community -wide electricity consumption was 411,382,15 kWh; 24`

Palm Desert accounts for approximately 13' of the Salton Sea air basin's population. This
percentage of the total vehicle miles traveled in the Salton Sea air basin of Riverside
County was attributed to Palm Desert.
Using the same methodology in the 2008 Inventory, vehicle miles traveled on Interstate 10
(heavy duty vehicles of +33,000lbs) were not factored into the 2013 inventory because the
Interstate falls outside of the Palm Desert boundaries.

In addition, this Inventory assumes the same special consideration for retired drivers used in
2008. It is assumed that retired drivers (65+ years) drive 23% less than non -retired drivers,
2013 Census data shows that approximately 33% of the population in Palm Desert are 65 "
years ,old or olders. However, 30 as assumed to remain consistent with the 2008
Inventory. These assumptions reduced vehicle miles traveled by passenger cars and light
duty trucks accordingly,

Municipal Employee Commute
P
In 2013, the City of Palm Desert had 116 employees.5 The following analysis accounts for
emissions generated by their commutes to and from work.
To maintain consistency with the 2008 GHG Inventory, the same assumptions about vehicle
type and miles traveled{ were used. It was assumed that 70% of City employees (81
employees) commuted by passenger car and 30% (35 employees) commuted by light
duty truck. Assumptions about round trip commuting distances were as follows: 10` of
employees have a 5-mile round trip commute, 30% have a 15-mile commute, and 60%
have a 25-mile commute. A total of 249 business days were counted; weekends and the
City's 12 observed holidays were excluded.
To estimate Natal annual vehicle miles traveled, the following equation was used:
Annual Vehicle Miles Traveled (V1 T) = (total slumber of employees) ;x (percentage of
employees by vehicle type) x (percentage of
employees by round trip commute mileage)
(number of annual trips)
As shown in the fallowing table, municipal employees commuted an estimated total of
77,680 miles in 2013.

Fleet Miles and Fuel Consumption
The City of Palm Desert ;contracts with the Riverside County Sheriff's Department. The
Sheriff's Department also provides services to Rancho Mirage, Indian Wells, and Thousand
Palms.
The vehicle miles traveled (VMT) for the Palm Desert; portion of the Sheriff's fleet was
provided by the Riverside County Sheriff's Department, totaling; 656,310 for 2013.E To
determine the gallons consumed for each vehicle, the vehicle miles traveled (VMT) were
divided by the vehicle's miles per gallon (MPG) which were obtained from the United
States Department of Energy fuel economy website.7 Mpg assumptions were basest on
2009-2014 model year mpg. averages for Ford Crown Vi torias, Toyota Camrys, and Nissan
Altimas. It was assumed that the sheriff fleet would achieve a lower mpg rating (10-1 ` )
due to department vehicle .specifications. These gallons totaled 38,606.

The large reduction in VMT and gallons from 2008 to 2013 is attributed to the
difference in data source. 2008 made assumptions for Palm Desert based on
total Riverside Sheriff VMT, while 2013 was based on actual Palm Desert data

Waste and recycling pick up services in Palm Desert are subcontracted to Burrtec Waste
industries with main offices at 9890 Cherry Avenue in Fontana. CA and with Palm Desert
offices and facility at 41575 Eclectic Street,
To remain consistent with the 2008 Palm Desert greenhouse gas inventory, the 2013 waste
transportation emissions are divided into two scopes.
Scope 1 emissions are emissions from local pickups and delivery to Burrtec sites in Palm
Desert as well as delivery to nearby Edam Hill Transfer Facility. Burrtec confirmed that the
Palm Desert mileage provided in 2008 has not changed in 2013.9

Scope 3 emissions are the emissions from the transportation of solid waste to the various
landfill facilities used, Similar to the Scope I emissions, the mileage, tractor -trailer MPG
ratings, semi trailer capacities, and the density of solid waste used in 2008 are still
applicable for 2013. The original 2008 data was derived from information provided by the
California Integrated Waste Management Board, Burrtec, and Palm Desert. It is assumed
that waste transported to Edam Hill will be transferred to Lamb Canyon Landfill in
Beaumont.

1. Desert Sands Unified School District
School Bus Vehicle Miles Traveled and Fuel
Consumption for Palm Desert
Using the 2012-2013 Bus Schedule provided by the Desert Sands Unified School District
(DSUSD), the bus routes were organized by school, the time of pick-up or drop-off, stop
location, and roufe number, The distance traveled was calculated by Google Maps and
only distances traveled in the City of Palm Desert were counted.
The number of miles traveled for the 2012-2013 school year for the entire bus fleet, which
includes elementary and middle school buses, was calculated to be 50,828.4 miles. It was
assumed that the starting point and end of day return of the school buses was at a bus
yard located in La Quinta, CA, It was also assumed that the one school year is
approximately 180 days, not including weekends.
To calculate the fuel consumption per school year, the number of school days was
multiplied by the total miles traveled per day and the product was divided by the school
busses' fuel consumption rate. According to DSUSD the bus fleet is comprised of a multi -fuel
type mix, of which approximately 45% is CNG, 30% is diesel, and 25% is gas'O. It was
assumed that the diesel and gas buses get approximately 8 miles per gallon, and the CNG
Muses get approximately 2.8 miles per 126.67 cubic feet of CNG. The fuel consumption
breakdown for the 2012-2013 school year is provided below,

schools did not provide school buses in 2013, thus reducing
overall mileage.

SunLine Transit Agency provides public transportation services to the Coachella Valley,
including the City of Palm Desert. Its entire service area covers approximately 1,120 square
miles, and its total passenger boardings reached 4.71 million in Fiscal Year 2012/13,"
Five (5) of SunLine's fixed bus routes traverse Palm Desert and provide direct service for City
residents. They include the following:
Route 3 - Palm Springs to Palm Desert, weekdays and weekends
Route 53 - Gerald Fore!/Cook/Palm Desert Moll, weekdays and weekends
Route 54 - Palm Desert to Indio, weekdays only
Route 11 1 - Palm Springs to Indio, weekdays and weekends
Route 220 - Palm Desert to Riverside (commuter link), weekdays only
All buses operating along these routes are fueled by Compressed Natural Gas (CNG).
ADA-compliant buses and vans provide curb -to -curb service on flex routes throughout the
City; however, their mileage and frequency is unpredictable. Therefore, these trips were
not included in this analysis,
M. -
Because the 5 routes serving Palm Desert extend into neighboring communities, SunLine
bus route maps and Google Earth were used to estimate only the route mileage within
Palm Desert's jurisdictional boundaries,-SunLine provided the number of daily bus trips
made along each route listed above, for both weekends and weekdays (where
applicable- Routes 54 and 220 operate only on weekdays). Using these data, total annual
bus mileage within Palm Desert was estimated° 303,88 miles/year.
Additional ;mileage was added to account for fuel consumed while buses travel to and from their transit stations at the beginning and end of each day: 57,969 miles/year. Buses
serving Routes 32, 53, 111, and 220 originate at the transit station located at 32505 Harry
Oliver Trail in Thousand Palms. Buses serving Line 54 originate at 83255 Highway 11 1 in Indio.
SunLine reported that its average CNG-operated bus gets 2.8 miles per 126.67 cubic foot of
CNG. This conversion factor was used in the model to estimate CNG transit fuel
consumption in Palm Desert.
As shown in the following table, the total annual mileage traveled on -route and to/from
transit stations in Palm Desert in 2013 is estimated at:361,867 miles.
