Eight Nonattainment Counties: Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, Waller

2008 RFP Demonstration Analysis - To determine if the 2008 RFP requirements are met, the 2008 target level of 

emissions is compared to 2008 controlled forecast inventory. For the HGB nonattainment area, an average 3% reduction of 

volatile organic compounds (VOC) and/or nitrogen oxides (NOX) per year out to an area’s attainment year are required for 

the 1997 eight-hour ozone standard to meet an RFP demonstration. For details of the requirements, please refer to Section 

7.3: Target Emissions Levels and RFP Demonstration of this SIP revision. The 2008 forecast inventory includes growth 

between the 2002 base year and the 2008 milestone year. The controlled forecast inventory has been reduced by 

subtracting the RFP control reductions from 2002 to 2008. If the 2008 controlled forecasted RFP emissions inventory (EI) is 

less than the 2008 RFP target level of emissions, the 2008 RFP requirement is satisfied.

Over Reductions 

1) Non-Creditable Fleet Turn Over Corrections - The reductions due to the pre-1990 Federal Motor Vehicle Control Program

(FMVCP) for on-road mobile sources are not creditable toward the reasonable further progress (RFP) requirements. The noncreditable reductions for each RFP milestone year are the difference between the on-road mobile adjusted base year (ABY)

emissions inventory (EI) for each RFP milestone year and the on-road mobile 2002 RFP ABY EI. Since the pre-1990 FMVCP fleet

turnover corrections are cumulative in the MOBLE6 model, the non-creditable reductions from previous milestone years must be

subtracted from the current milestone year to obtain the non-creditable reductions between milestone years. The FMVCP noncreditable reductions are used to calculate the target value for each RFP milestone year.

3% per year Reductions - The Federal Clean Air Act (FCAA) mandates that a 3% per year volatile organic

compounds (VOC) reduction, net of growth, occur between 2002 and the attainment year. The reductions must be

demonstrated for the six-year period from 2002 to 2008, and every three years after 2008 until the attainment year,

2011, 2014, 2017 and 2018. Nitrogen oxides (NOX) reductions may be substituted for VOC reductions. An additional

3% reduction must be demonstrated as contingency measures for the one-year period following the attainment year,

2019. The division of the percent reductions between VOC and NOX are entered in the "Enter % for RFP Cont &

Conf SM" sheet. 

1) The adjusted base year (ABY) emissions inventory (EI) is the Base Year Emissions minus the non-creditable onroad mobile reductions. It is calculated by adding the ABY EI for point, area and non-road to the ABY for on-road.

When the ABY EI is multiplied by the required percent reduction, the result is the reductions required.

2) On-road Mobile ABY Inventories - The on-road mobile ABY EI for each milestone/attainment year are calculated

using 2002 vehicle miles travelled (VMT) and MOBILE6 emission factors for each reasonable further progress

(RFP) analysis year with only the effects of pre-1990 FCAA controls turned on. The pre-1990 FCAA controls include

the 1992 Low Reid Vapor Pressure (RVP) Gasoline control and the pre-1990 on-road mobile source Federal Motor

Vehicle Control Program (FMVCP) controls. The on-road mobile ABY EI is equal to the on-road mobile ABY EI

minus the non-creditable FMVCP reductions.

amount must be less than or equal to the excess reductions. Entering a percent safety margin below will update the

Motor Vehicle Emissions Budget (MVEB) calculation to include the percent safety margin entered. The amount of the

safety margin will automatically be checked to verify it is less than the excess emissions. If not, a "check safety margin"

will appear in the MVEB calculation box.

A 3% per year reduction is required for HGB for every year from the 2002 base year until the attainment year. The 

reduction is required to be demonstrated six years after the base year, 2008, every three years after that year, 2011, 

2014, and 2017, and the attainment year 2018. The total reduction for 2008 is 18% (3% times 6). The total reduction for 

2011, 2014 and 2017 is 9% (3% times 3). The reduction required for 2018 is 3% (3% times 1). What percentage of 

nitrogen oxides (NOX) and volatile organic compounds (VOC) reductions will be used to demonstrate reasonable further 

progress (RFP) for 2008, 2011, 2014, 2017, and 2018? The analyst only needs to input the NOX percent. The VOC

The biogenics emissions are subtracted from the 2002 reasonable further progress (RFP) base year inventory as the first step of the RFP 

demonstration calculations. That is the only step for which biogenic emissions are required. Therefore, only the 2002 base year inventory for 

biogenics is entered on this page.

Different VOC adjustments were used for the uncontrolled and controlled inventory projections. These adjustments were based on the most current science available 

for each base year used to project the uncontrolled and controlled inventories. The difference in emissions resulting from these two different adjustments has not been 

claimed as a reduction for the RFP demonstration.

1) Biogenic emission are part of the 2002 Base Year Inventory, but are not included in the RFP calculations. One step in the RFP calculations is to subtract all 

biogenic emissions from the base year inventory.

2) Input lines allow for input of emissions from outside the subject counties to be included in the calculation of the RFP base year emissions. Emission 

reductions from the included sources can then be used to meet RFP requirements.

3) Values in lines should be input as positive values for emissions from outside the area that need to be included in the calculations and as negative values for 

emissions which need to be excluded from the RFP calculations.

Explanation: The control strategy name, control reduction amount, the status of inclusion of the control in the reasonable further progress (RFP) 

calculations, and whether the control is for on-road mobile sources were all input in the "30 Enter Reductions 2008" sheet. The reduction is the 

reduction that is creditable from each control between 2002 and 2008. If the control has been turned off by inputting a "No" in the "Use this Control for 

2008 RFP Demonstration?" column, the spreadsheet will put a zero in for the reduction for that control on this sheet, even if a positive value for the 

control was input into the "Enter Reductions 2008" sheet. If it was intended to have a positive reduction for the control, but there is a zero, go back to 

the "Enter Reductions 2008" sheet and change the "No" to a "Yes," indicating that the control will be used for RFP demonstration.

Explanation: The control strategy name, control reduction amount, the status of inclusion of the control in the reasonable further progress (RFP) 

calculations, and whether the control is for on-road mobile sources were all input in the "30 Enter Reductions 2008" sheet. The reduction is the 

reduction that is creditable from each control between 2002 and 2008. If the control has been turned off by inputting a "No" in the "Use this Control for 

2008 RFP Demonstration?" column, the spreadsheet will put a zero in for the reduction for that control on this sheet, even if a positive value for the 

control was input into the "Enter Reductions 2008" sheet. If it was intended to have a positive reduction for the control, but there is a zero, go back to 

the "Enter Reductions 2008" sheet and change the "No" to a "Yes," indicating that the control will be used for RFP demonstration.
