Dear Dr. Armendariz:

On March 10,2010, the Texas Commission on Environinental Quality (Commission) adopted a revision to the

state implementation plan (SIP) for demonstration of reasonable further progress for the Houston-GalvestonBrazoria (HGB) 1997 eight-hour ozone nonattainment area.

The Commission adopted the HGB Reasonable Further Progress (RFP) SIP revision, demonstrating that the

RFP emissions reduction requirement will be met for the six-year period (2003-2008) beginning Janumy 1 ofthe

year following the year used for the baseline emissions inventory (2002) and all remaining three-year periods

after the first six-year period (2009-2011, 2012-2014, and 2015-2017) out to the area's attainment date (2019).

This SIP revision also sets the nitrogen oxides (NOx) and volatile organic compounds (VOC) motor vehicle

emissions budgets (MVEB) for transportation conformity purposes for the milestone years 2008, 2011, 2014,

2017, and 2018.

Enclosed are the proposed revision to the SIP, a public hearing certification, a complete record of the public

hearings, and the accompanying order. I look forward to your expeditious approval ofthis SIP revision.

Sincerely,

~~;dAtv- Bryan W. Shaw, Ph.D.

2008 RFP Demonstration Analysis - To determine if the the 2008 RFP requirements are met the 2008 Target Level of 

Emissions is compared to 2008 controlled forecast inventory. 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. The RFP Target level of Emssions for all milestone years is calcluated

on the "Calc Targets" page.

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 be

subtracted 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. When the ABY EI is multiplied by the required

percent reduction the result is the reductions required

2) On-road Mobile Adjusted Base Year Inventories - The on-road mobile adjusted base year inventories for each

milestone/attainment year are calculated using 2002 VMT and MOBILE6 emission factors for each RFP analysis

year with only the effects of Pre-1990 CAA controls turned on. The pre-1990 CAA controls include the 1992 RVP

control and the pre-1990 on-road mobile source FMVCP controls. The on-raod mobile ABY EI is equal to the onroad mobile BY EI minus the non-creditable FMVCP reductions.

A 3 percent 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 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.

Notes: 

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 

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. E

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 neg

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 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.

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.
