1.0 I NTRODUCTION

EMFAC2011

- PL (Ver 1.1) is a new simplified tool that reports emission rates for project

- level assessments. EMFAC

- PL

uses emissions and activity data from EMFAC2011

- SG module inventory files ( which consists of the default inventories of

the two EMFAC modules, i.e. EMFAC

- L DV and EMFAC

- HD ) to back

- calculate default emission rates . The EMFAC

- PL

tool also reports effective CO2 emissions with Pavley

- I and Low Carbon Fuel Standard ( LCFS ) benefits

. EMFAC2011

- PL

is develop ed on the Microsoft® Access platform, and generates outputs in Microsoft Excel format (*.xls).

EMFAC2011

- PL processes data at a sub

- area level ( area defined by County

- Air Basin

- District boundaries [ CoABDis ] or

Geographic Area Index [GAI] ) . Therefore, in order to process regional scenarios (State, Air Basin, Air District, MPO,

County), the tool process es all sub

- a reas in its domain and aggregate the results. That is, for a single “Statewide”

regional modeling scen ario, the model will aggregate the emission rates of all 69 sub

- areas. Similar to EMFAC2011

- SG,

the EMFAC2011

- PL tool allows users to generate MPO

- level outputs in addition to the Statewide, Air Basin, Air District,

County, and Sub

- Area level outputs common in EMFAC2007

.

2.0 M ODEL O PERATION A ND L OGIC

Since the fleet characteristics (vehicle type, technology, and age distributions) and vehicle use patterns ( vehicular miles

travelled or VMT

, and speed) vary by local regulatory and planning agencies , the vehicle usage and speed profiles vary

greatly at the sub

- area level (GAI or CoABDis). T he EMFAC

- PL tool process es emission factors at the sub

- area level

, and then aggregate the data at the desired regional level

.

EMFAC

- PL uses the combined outputs from the two models (EMFAC

- LDV and EMFAC

- HD) at the most detailed level

(i.e. EMFAC “Burden” output level) disaggregated by Speed (5

- MPH increments) as the base inventory. When a user

models a scenario, the EMFAC

- PL tool imports the data from the corresponding base inventory file, and disaggregates

the data into different parameters.

Based on the modeling parameters, the EMFAC

- PL tool u ses the following equations to calculate the emission rate s by

Vehicle Category (VC) for the EMFAC2011 vehicle categories :

( )

### PTSD

- MSAB Page 4

Idling Emission Rates for HD vehicles were obtained from the HD Idling Database at the Sub

- Ar ea level

( http://www.arb.ca.gov/msei/emfac2011_idling_emission_rates.xlsx ), and aggregated at the 15 Air Basins and at the

statewide total levels using population

- weighted aggr egation. If the user selects the aggregated “California” option, then

the statewide data for the corresponding calendar year and season are looked up. For every other region, an analysis of

the Air Basin of largest influence was conducted using the 1990 default population s

. D epending on the region selected by

the user in EMFAC

- PL tool, the tool look s up the Air Basin with the largest influence, and assigns the HD Idling Emission

Rates. For example, Los Angeles County lies in two Air Basins: South Coast Air Basin and the Mojave Desert Air Basin.

However, since over 97 % of the vehicles registered in the LA County were in the South Coast Air Basin, the SCAB HD

Idling Emission Rates were assigned to LA County. The HD Idling Lookup Table is presented in App endix C.

The EMFAC2011 vehicle category scheme is the most detailed scheme used by the model. For other aggregated vehicle

category schemes (EMFAC2007, Truck/Non

- Truck, ALL vehicles), t he tool uses similar weighted

- aggregation to calculate

the process emission rates, except when calculating running emission factors. When the EMFAC2011 vehicle categories

are aggregated up to a higher category scheme for running emission rates , the factors are weighted using the total VMT

contribution of the EMFAC2011 vehicle to the new ly aggregated category. That is, if the user selects the “Truck/Non

Truck” category scheme for a scenario where ‘LDA

- GAS’ has a total VMT contribution of 35% to the ‘Non

- Trucks’

category, then all the speed bins for the ‘Non

- Trucks’ category will contain 35% of the emission factors from ‘LDA

- GAS’.

In other words

, it assumes that when a standard fleet with a constan t fleet composition moves at two different speeds

(e.g. 35 MPH in one leg of the project, and 50MPH in the another leg), it should have identical contributions from all the

constituents. Th is way , the EMFAC

- PL tool is able to accurately calculate consiste nt fleet

- wide average emission factors

at all speeds which are needed for project

- level assessments

.

Note: T he Web Database uses VMT contribution s by speed to aggregate the emission rate s for Medium

- Heavy and

Heavy

- Heavy Duty Trucks in the EMFAC2007 categor y scheme ( MHDT and HHDT ) . Since each vehicle clas s is

operated on different road type, speed limits, time of day, day of week, etc., the VMT contribution profiles for vehicles at

different speed bins can be different from their total VMT contribution profile. Therefore, for MHDT and HHDT vehicles in

EMFAC2007 scheme , the aggregation method in the Web Database may produce different emission factors from the

EMFAC2011

- PL tool

. Although the emission factors from the web database are consistent with the planning inventories,

they may not be the most suitable representa tion of fleet

- wide average emission factors at different speeds for project

level analyses for those vehicles (MHDT, HHDT)

.

3.0 MODEL E XTRACTION

1. Extract the “ EMFAC2011

- PL (Ver 1.1) .zip ” file to the root C drive (“C: \ ”)

2. The process will create a folder on the root C Drive called “EMFAC2011

- PL (Ver 1.1) ” and will contain the

“EMFAC2011

- PL (Ver 1.1) .mdb” file

4.0 SYSTEM REQUIREMENTS

The EMFAC2011

- PL (Ver 1.1) tool requires Microsoft XP or a more recent operating system; and Microsoft Access and

Excel 2003 or newer to run the tool

.

EMFAC2011

- PL also requires that EMFAC2011

- SG (Ver 1.1) is installed on the user’s computer since the PL tool uses

the inventory files from the SG module.
