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 EI is less than the 2008 RFP Target Level of Emissions the 2008 RFP requirement is satisfied.

3) Excess emissions reductions (Line 5) may be used to provide a transportation conformity safety margin. The safety margin must be less than or equal to the excess emissions reductions. 2) To calculate the final excess or shortfall of for each milestone/attainment year, thecontrolled RFP emissions forecast is subtracted from the RFP Target level of Emissions.

On-road Mobile ABY EI Non-creditable Fleet Turn Over Reductions

1) Non-creditable Fleet Turn OverCorrections - The reductions due to the Pre-1990 FMVCP for on-road mobile sources are not creditable toward the RFP requirements. The non-creditable reductions for each RFP milestone year are the difference between the on-road mobile ABY EI for each RFP milestone year and the on-road mobile 2002 RFP ABY EI. Since the Pre-1990 FMVCP fleet turnonver corrections are cumulative in the MOBLE6 model, the noncreditable reductions from previous milestone years must besubtracted from the current milestone year to obtain the non-creditable reuctions between milestone years. The FMVCP noncreditable reductions are used to calculate the target value for each RFP milestone year.

Notes: 3% per year Reductions - The Clean Air Act (CAA) mandates that a 3 percent per year VOC reduction, net of growth, occur between between 2002 and the attainment year. The reductions must be demonstrated for the 6 year period from 2002 to 2008, and every three years after 2008 until the attainment year, 2011, 2014, 2017 and 2018. 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 data entry sheet with tab name "Enter % for RFP Cont & Conf SM" .

1) The ABY EI is the Base Year Emissions minus the non-crediable on-road mobile reductions. It is calculated by adding the BY EI for point, area and non-raod to the ABY for on-road.

The reduction is required to be demonstrated 6 years after the base year, 2008, every 3 yeaars 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 percent (3% times 3). The redution required for 2018 is 3 percent (3% times 1). What percentage of NOx and VOC reductions will be used to demonstrate RFP for 2008, 2011, 2014, 2017, and 2018 ? The analist only needs to input the NOx percent. The VOC percent will be calculated automatically based upon the total required and the percent from NOx.

If there are excess RFP control reductions, a transportation conformity safety margin is allowed. The safety margin amount must be less than or equal to the excess reductions. Entering a percent safety margin below will update the 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 safty margin" will appear in the MVEB calculation box.

A 3 Percent 2008 to 2009 and 2018 to 2019 Contingency Measures Reduction is Required. Input only the percent of the reductions that will be from NOx. The VOC value will be calculated automatically as 3 minus the NOx percent. For 2018 to 2019 a 3% contingency is also required for the attainment demonstration.

Explanation: The control strategy name, control reduction amount, the status of inclusion of the control in the RFP calculations, and whether or not the control is for on-road mobile sources were all input in sheet "28 Enter Reductions 2008". The reduction is the reduction that is creditable from each control between 2002 and 2008. If the controll 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 Sheet and change the No to a Yes indicating that the control will be used for RFP demonstration.
