Maintenance Measures

### App. IV-xvi-2 MAINTENANCE MEASURE #1

Summer Fuel Reformulation: California P hase 2 and Federal Phase II Reformulated Gasoline with 7 psi from May 1 through September 30

### App. IV-xvi-3 The “Summer Fuel Reformulation: Californi a Phase 2 and Federal Phase II Reformulated Gasoline with 7 psi from May 1 through September 30" measure affects emissions from onroad vehicle gasoline-powered engines. With the implementation of this measure, a cleaner burning formulation of gasoline than would otherwise be used will be sold in the modeling area during the ozone season. The methodology used toestimate the benefit is described below. In this analysis, all onroad credit for committed measure package gasoline is applied using the MOBILE6 model.
To estimate the effect of the expected gasoline formulation on onroad emissions, the MOBILE6 model was used. MOBI LE6 accepts as input data fo r the gasoline vapor pressure (RVP), oxygenate content, and sulfur content. The MOBILE6 model runs performed for this analysis in 2025 incorporate the committed ma intenance measure package RVP value (7.0 psi). Additionally, in MOBILE6, a flag is available to indicate that reformulated gasoline is to be assumed in the analysis.

To estimate the effect of the cleaner burning gasoline, MO BILE6 was performed using both the committed measure package and the baseli ne (2005 conditions) formulations. The emissions estimated by the two runs we re processed through the M6Link program independently and the difference in final emi ssions estimates was calculated. The reformulated gasoline was set to reflect the southern location of Arizona using the "S" option. The credit for this m easure is applied to the entire m odeling domain as it is assumed that the gasoline quality is consistent across the modeling domain due to the structure of the Arizona gasoline distribution system. Additionalinformation about the options available to the user of MOBILE6 for the modeling ofgasoline quality may be found on pages 148 through 167 of the User’s Gui de to MOBILE6.1 and MOBILE6. 2 Mobile Source Emission Factor Model , October 2002.
No specific credit was taken for reformu lated gasoline on nonroad emissions as it is assumed that the very stringent nonroad engine standards include thatthe engines will use cleaner burning reformulated gasoline.
The baseline inventory reflected actual moni tored gasoline formulation qualities from the summer season. The impact of this maintenance measure in 2025 is a 0.1% increase in anthropogenic NOx emissions and a 0.5% dec rease in anthropogenic VOC emissions.

### App. IV-xvi-4 MAINTENANCE MEASURE #2
Phased-In Emission Test Cutpoints

### App. IV-xvi-5 The “Phased-In Emission Test Cutpoints” m easure affects onroad emissions. With the implementation of this meas ure, vehicles which are s ubject to the enhanced I/M program are held to a stricter set of cutpoints t han would otherwise be the case. The stricter cutpoints were implemented in January 2000. If a vehicle exceeds the emission levels set by the cutpoint for carbon monoxide, hydrocarbons, or NOx, the vehicle fails the test.
The Arizona Department of Environmental Qua lity (ADEQ) provided a table of emission testing cutpoints for each model year vehicl e subject to the enhanced I/M program in the May 28, 2001 ADEQ memo Cut points for IM147 for MOBILE6 . These cutpoints are entered into a data file in a format appropriate for i nput to the MOBILE6 model. The format for the table appropriate for input to MOBILE6 may be found in section 2.8. 9.4.g of the User’s Guide to MOBILE6.1 and MOBILE6.2: M obile Source Emission Factor Model , EPA420-R02-028, October 2002.
The composite cutpoints (I/M147 program) thatreflect the enhanced program are indicated in the following table. The LDGV cutpoints were used in the MOBILE6 Block 1 cutpoint values. The LDGT1 cutpoints were used in Block 2. The LDGT2 cutpoints were used in Block 3.
Model Year Vehicle Class Hydrocarbons CO NOx 1981-1982 LDGV 3.00 25.00 3.50 1983-1985 LDGV 2.40 20.00 3.50 1986-1989 LDGV 1.60 15.00 2.50 1990-1993 LDGV 1.00 12.00 2.50 1994+ LDGV 0.80 12.00 2.00 1981-1985 LDGT1 4.00 40.00 5.50 1986-1989 LDGT1 3.00 25.00 4.50 1990-1993 LDGT1 2.00 20.00 4.00 1994+ LDGT1 1.60 20.00 3.00 1981-1985 LDGT2 4.40 48.00 7.00 1986-1987 LDGT2 4.00 40.00 5.50 1988-1989 LDGT2 3.00 25.00 5.50 1990-1993 LDGT2 3.00 25.00 5.00 1994+ LDGT2 2.40 25.00 4.00

While the previous table lists the cutpoints used for model years back to 1981, due to the structure of MOBILE6, only t he cutpoints back to the model year 2001 are considered when performing a 2025 run. This is because the MO BILE6 model only consi ders the most recent 25 model years in any particu lar run. In 2025, the 25 th

### model year included in the modeling

### App. IV-xvi-6 is a 2001 vehicle. The enhanced I/M program with the I/M cutpoints was removed as the base case.

The benefit from the enhanced I/M program with the cut points was estimated by running the M6Link model with the MOBILE6 outputs developed using the base case without the enhanced I/M program and then rerunning M6Li nk with the MOBILE6 outputs developed using the enhanced I/M program wit h the cutpoints. In both cases, MOBILE6 was run with a five year grace period from the I/M program for the newest model year vehicles.
The anthropogenic emission reducti ons attributable to this maintenance measure in 2025 are less than 0.1% for both NOx and VOC.

### App. IV-xvi-7 MAINTENANCE MEASURE #3

One Time Waiver from Vehicle Emissions Test

### App. IV-xvi-8 The “One Time Waiver from Vehicle EmissionsTest” measure affects onroad emissions. With the implementation of th is measure, vehicles are al lowed no more than a single I/M waiver after January 1, 1997. The methodology used to estimate the emissions reduction is described below.
MOBILE6 uses as input the waiver rates for two age groups of vehicles. The first age group includes vehicles whose model year is older than 1981. The second age group includes vehicles whose model year is equal to or newer than 1981. It is assumed that the waiver rates for the first and second age groups without this control measure would be four percent and three percent, respectively. The base case waiver rates incorporate no set limit on the number of waivers which a given vehicle may re ceive. This measure sets a limit of one on the number of waivers which any vehicle may receive.
It has been estimated that the average remaini ng life span of a vehicl e which has received a waiver is three years (page E-5 of Feasibility and Cost-Effect ive Study of New Air Pollution Control Measures Pertaining to Mobile Sources , Sierra Research, Inc., June 1993). The waiver rate, which was four percent for pre-81 model years and three percent for 1981 and later model years, was changed to 0.709 percent and 0.781 percent in the MOBILE6 input for the 2025 base case, respectively. The credit for this measure was applied exclusively to Area A (S.B. 1427).
The anthropogenic emission reducti ons attributable to this maintenance measure in 2025 are 0.1% for NOx and less than 0.1% for VOC.

### App. IV-xvi-9 MAINTENANCE MEASURE #4
Tougher Enforcement of Vehicle Registration and Emission Test Compliance

### App. IV-xvi-10 The “Tougher Enforcement of Vehicle Registration and Emission Test Compliance” measure affects onroad emissions. With the implementation of this m easure, the number of vehicles which are expected to be regi stered in the nonattainment area and tested in the I/M program is increased, resulting in a cleaner onroad vehicle fleet. The methodology used to estimate the emissions reduction is described below.
Without this control measure, the weighting factors of I/Mand non-I/M emission factors from MOBILE6 were assumed to be 89.6 percent and 10.4 percent, respectively. This measure was implemented by adjusting the weighting factors between I/M and non-I/M emission factors from MOBILE6 in the M6Link control file.
The Report of the Governor’s Ai r Quality Strategies Task Force , December 2, 1996 estimated that an additional 41,000 vehicles would be emission tested as a result of this measure. This estimate was confirmed with the Arizona Departmentof Environmental Quality and the Arizona Department of Transportation as being a reasonable but conservative estimate of the number of vehicl es registered as a result of this measure.
The number of vehicles registered in Maricopa County during the time of the Task Force estimate was approximately 1.83 million. T he inspection of an additional 41,000 vehicles would be an additional 2.0 percent of the vehicl es being emissions tested. It is assumed that the increase in the vehi cles being emission tested, taken as a fraction, would remain constant or increase over time. In other word s, the number of vehicl es which will participate in the I/M program in 2025 would be increas ed by 2.0 percent compared with the case without this control measure. By implementing this control m easure, the weighting factors were changed from 89.6 percent and 10.4 percent to 91.6 percent and 8.4 percent for I/M and non-I/M emission factors, respectively.
The anthropogenic emission reducti ons attributable to this maintenance measure in 2025 are 0.1% for NOx and less than 0.1% for VOC.

### App. IV-xvi-11 MAINTENANCE MEASURE #5
Federal Nonroad Equipment Standard

### App. IV-xvi-12 In 1998 EPA issued a final rule setting more stringent Tier 2 and Tier 3 emission standards for new diesel nonroad equipment (EPA, Federal Register, Vol. 63. No. 205, October 23, 1998, pp. 56967-57023). The Tier 2 program phased in more stringent standards for all equipment between 2001 and 2006 and Ti er 3 imposed even more stringent standards for 50 to 750 hp engines beginning in 2006 through 2008.

In 2004 EPA issued the Clean Air Nonroad Diese l - Tier 4 Final Rule that requires manufacturers to produce nonroad engines wit h advanced emission-control technologies that will reduce emissions by mo re than 90 percent (EPA, FederalRegister, Vol 69, No. 124, June 29, 2004, pp. 38958-39273). The Tier 4 standards apply to nonroad engines less than 25 hp, beginning in 2008. Larger engines must comply with the Tier 4 standards by 2011- 2015.
This measure was modeled by running the EPA NONROAD model for 2005 using the 2025 equipment growth factors and comparing this with a 2025 run using t he 2025 growth factors. The decrease in emissions between 2025 and 2005 represents the impact of the more stringent federal nonroad diesel equipment standards implemented between 2005 and 2025.
The impact of this measure in 2025 is a 7.9% decrease in anthropogenic VOC emissions and a 16.5% decrease in anthropogenic NOx emissions.

### App. IV-xvi-13 MAINTENANCE MEASURE #6
Expansion of Area A Boundary

### App. IV-xvi-14 Arizona Legislature passed H.B. 2538 in 2001 which expands the boundaries of Area A. Previously, the Area A boundaries followed the boundaries definedby S.B. 1427, which was passed by the Arizona Legislat ure in 1998. Specifically , H.B. 2538 expands the boundaries of Area A past those descri bed in S.B. 1427 adding additional portions of Maricopa County west of Goodyear and Peoria and a small piece of land on t he north side of Lake Pleasant. The implementation of air quality measures in the areas described in H.B. 2538 began on January 1, 2002, except for public sector alternative fuel requirements that are phased in over a seven year period.

“Area A” means the area delineated as follows:
(a) In Maricopa County: Township 8 North, Range 2 East and Range 3 East Township 7 North, Range 2 West Through Range 5 East Township 6 North, Range 5 West Through Range 6 East Township 5 North, Range 5 West Through Range 7 East Township 4 North, Range 5 West Through Range 8 East Township 3 North, Range 5 West Through Range 8 East Township 2 North, Range 5 West Through Range 8 East Township 1 North, Range 5 West Through Range 7 East Township 1 South, Range 5 West Through Range 7 East Township 2 South, Range 5 West Through Range 7 East Township 3 South, Range 5 West Through Range 1 East Township 4 South, Range 5 West Through Range 1 East
(b) In Pinal County: Township 1 North, Range 8 East And Range 9 East Township 1 South, Range 8 East And Range 9 East Township 2 South, Range 8 East And Range 9 East Township 3 South, Range 7 East Through Range 9 East
(c) In Yavapai County: Township 7 North, Range 1 East And Range 1 West Through Range 2 West Township 6 North, Range 1 East And Range 1 West
It is important to note that under A.R.S. 49-406 (A), MAG has statutory authority to conduct nonattainment area planning within Maricopa County. However, MAG does not have air quality planning authority for eitherPinal or Yavapai Counties.
Under A.R.S. 49-406 (K), the Arizona Department of Environmental Quality has air quality planning authority to adopt SIP m easures in those portions ofArea A in Pinal and Yavapai Counties where MAG does not have authority. For ozone, the committed measures include the Vehicle Emissions Inspection Program, Cl ean Burning Gasoline Program, Stage II Vapor Recovery Program, Trip Reduction Program, Vol untary Vehicle Repair and Retrofit Program, and Traffic Signal Synchronization. For carbon monoxide, the committed measures include

### App. IV-xvi-15 the Vehicle Emissions Inspection Program , Clean Burning Gasoline Program, Trip Reduction Program, Clean Burning Fireplace Construction and Conversion Program, No Burn Days and Public Participation Program s, and Voluntary Vehi cle Repair and Retrofit Program. MAG anticipates that ADEQ will al so provide notice and public hearing on this plan, perhaps jointly with MAG, prior to ADEQ ’s adoption of the plan under A.R.S section 49-404 and ADEQ's subsequent submittal of the plan to EPA for approval. Emission reduction credit for this meas ure applies only to the areabetween the Area A boundary established by S.B. 1427 and the Area A boundary established by H.B. 2538.
This measure was modeled by running M6Linkusing the expanded GIS coverage files for Area A (S.B. 2538) and comparing with a run appl ying the previous GIS coverage files for Area A (S.B. 1427). The difference in emissi ons between these two runs represents the impact of the expansion of Area A boundaries implemented in 2025.
The impact of this measure in 2025 is a 0. 1% decrease in anthropogenic NOx emissions and less than a 0.1% decrease in anthropogenic VOC emissions.

### App. IV-xvi-16 MAINTENANCE MEASURE #7
Ban Open Burning during Ozone Season

### App. IV-xvi-17 The measure was adopted by Senate Bill 1552 on June 20, 2007 along with the liquid leaker test rule. This measure prohibits open outdoor fires during May 1 through September 30 of each year during the ozone season. The ru le also prohibits all indoor burning using fireplaces in commercial, non-residential establishments, such as hotels and restaurants, during Restricted-Burn Periods with the exception of those that use gaseous fuels.

The emission reductions attributable to thismeasure were estimated by ADEQ. The anthropogenic emission reductions in 2025 are less than 0.1% of VOC and NOx.

WRF Meteorology Simulations

Appendix VI-iii describes the modeling domains, episodes selection, input data, configurations, and performance evaluation of the WRF modeling.

### App. VI-iii-2 The National Center for Atmospheric Research (NCAR) Weather Research and Forecasting (WRF) modeling system is a next-generation mesoscale forecast model and data assimilation system (http://wrf-model.org/i ndex.php). WRF is efficient in a massively parallel computing environment, offering m any state-of-the-art physics and dynamics options that are applicable in di fferent spatial and temporal sca les. It is expected that WRF as a high effective resolution mesoscale m odel (Skamarock, 2004) will eventually replace the Fifth Generation Mesoscale Model (MM5) of which the development and maintenance were frozen in 2004.
MAG contracted ENVIRON to provide MM5 meteorological data for the CAMx eight-hour ozone modeling for MAG Eight-Hour Ozone Pl an (MAG, 2007). MAG decided to use the same MM5 meteorology and test the WRF meteorology with air quality models such as CAMx and CMAQ for the maintenance modeling demonstration. The principal components of the WRF modeling system include the WRF Software Fram ework (WSF); the dynamic solver, either the Advanced Research WRF (ARW) dynamic solver developed primarily at NCAR or the Nonhydrostatic Mesoscale Modelsolver developed at National Centers for Environmental Prediction (NCEP); the WR F Preprocessing System (WPS); the WRF Variational Data Assimilation (WRF-Var) system; numerous physics packages contributed by WRF partners and research community; and several graphics programs and conversion programs for postprocessing. The ARW dynamic solver in WRF v2.2 that released in December 2006 was applied in this modeling study.
Modeling Domain and Selected Episodes

The WRF domain is the same as the MM5 modeling used in the maintenance demonstration (see Section II), where three nested domains are used (Table 1). The central latitude and longitude of the WRF LC P coordinate are 34°N and 111°W; and the conic true latitudes are 45°N and 33°N. The LC P central longitude ali gns along the central longitude of UTM zone 12 (111°W), on which t he CAMx domain is defined. The CAMx and CMAQ simulations are carried on the 12 km and 4 km domains. The CAMx and CMAQ domains are slightly inset several grid cells on each side from the WRF domains as a way to remove boundary “noise” near the WRF boundaries.

The same vertical structures of MM5 and CAMx used in maintenance demonstration are applied in the WRF and CMAQ simulations. Moredetails on the vertical structures of MM5 and CAMx are available in Section II.
This study conducts WRF and CMAQ modeli ng for the three episodes used in the maintenance demonstration (see Section V).
WRF Input Data and the Meteorological Monitoring Data
Most of the required datasets for the WRF modeling have been procured directly from the NCAR web sites. This include a terrestrialdataset such as terrain elevation, landuse/landcover (LULC), soil types, and so on (WRFM, 2008), and large-scale meteorological analysis fields (UCAR, 2008). The static geographical data has the finest resolution of 30'. The analyses are extracted from the NCEP NAM/Eta Data Assimilation System (EDAS) that provides 40 kmNorth American analyses every 3 hours.
Meteorological observations have been collected by MAG from three monitoring networks throughout Arizona, including surface sites from the Arizona Meteorological Network (AZMET) and the NOAA/NWS, and four upper ai r profiler sites operated by the NOAA’s Forecast Systems Laboratory (FSL). In addition, the standard NCAR/NWS hourly surface observation dataset (DS472) was obtained toaugment the MAG databases and cover the entire region encompassed by the WRF domain. The DS472 dataset was used in the WRF performance evaluation.
WRF Simulation Design and Performance Evaluation
The WRF Preprocessing System (WPS) was used to define the modeling domains and interpolate the terrestrial and meteorol ogical data onto the modeling domains. The interpolated meteorological data were t hen used to derive initial and boundary condition data and FDDA nudging files for WRF modeli ng. The boundary condition is developed for the 36 km parent domain, and the 12 km and t he 4 km domains are two-way nested. The performance evaluation was made using METSTAT developed by ENVIRON. The June

### App. VI-iii-4 episode was tested by applying differentphysics and dynamics options. Similar configurations were applied to the July and August episodes.
The June Episode
Physics and configuration options of the WRF model are outlined in this section. The same MM5 configuration as used for the MAG Ei ght-Hour Ozone Plan was applied to the WRF configuration, which has been proved to produce the best overall performance in the desert southwest (MAG, 2007). The difficulty is that several key physics options used in the MM5 modeling, such as the Pleim-Chang (ACM) boundary layer scheme and the Pleim-Xiu land surface model, are not available in the latest released version of WRF when this study was made. Therefore, the Mello r-Yamada-Janjic (Eta) boundary layer scheme and the Noah land-surface model were first tested. Kain-F ritsch (KF) instead of Betts-Miller cumulus scheme was applied, since the MM5 experiments found that the tem perature and moisture performance improved noticeably wit h the KF scheme. Table 2 lists the configuration for the first successful run of the June episode.
The WRF average daily performance statistics of Run1 are listed in Table 3. When they are compared with the MM5 statistics as listed in Table 3-1 in Appendix III-I of the MAG EightHour Ozone Plan (MAG, 2007), it is found that most WRF statistics are better than the MM5 statistics except for temperature bias. The hourly statistics of te mperature (Figure 1a), however, reveals that the negative temperature bias in WRF occurs at night, while there is a minimal positive bias during the day. On the contrary, MM5 has a rather large positive temperature bias around noon, wh ich compensates some of the negative bias at night. When the WRF meteorology from Run1 was tested with CMAQ, it was found that the overprediction of ozone on June 5 was worse than that predicted wit h MM5 meteorology.
Run2 was implemented wit h the YSU PBL scheme. However, there were still several hot spots with very high ozone concentrations on June 6 when Run2 was tested with CMAQ. The WRF Run3 for the June episode that was successfully tested with CMAQ applies the Medium Range Forecast (MRF) PBL model. The hourly time series statistics of surface wind, temperature, and humidity of Run3 are illustrated in Figure 1. The daily average performance statistics of Run3 are listed along with Run1 in Table 3. Most of the statistics are not as good as Run1, while they are veryclose. Figure 1a shows that both the simulated wind speed and direction agree well wit h the observations from May 31 to June 3, when the diurnal cycle of morning north- easterly and afternoon south-westerly wind is

### App. VI-iii-6 notable and there is strong wind in the afternoon. On June 5, the simu lated north-easterly persisted into the afternoon, while the observed wind direction shifted to south-westerly before noon. This would be caused by the passage of an upper-level trough and the associated weak front that depressed the meso-scale circulation induced by the topography of the basin. The no-nudging strategyto correct the wind direction problem was tested with WRF, but resu lts were the same as the one with nudging. Therefore, this problem will be further manifested in the CM AQ/WRF test on June 5 when the persisted north-easterly wind caused ozone to be over-p redicted. Sensitivity tests were done by applying different dynamic damping options, e.g. the gravity wave absorbing layer, the vertical-velocity damping, the sixth order numerical diffusion, but the statistics of the performance was not improved noticeably.

### App. VI-iii-10 The July and August Episodes
The same configurations as used in Run3 ofthe June episode were applied in testing WRF for the July episode. The hourly time series ofsurface wind, temperat ure, and humidity are illustrated in Figure 2. The da ily average performance statisti cs are listed in Table 4. It appeared that wind simulation was not as good as MM5, while t he temperature and humidity simulations in WRF were much better than MM5. Besides, t he wind simulation of WRF was not as good as the June 2002 episode, which might be due to the persistent light wind that is hard to simulate.
The August episode is characterized with high humidity caused by freque nt precipitations. A more updated and sophisticated microphysics scheme called the Thompson scheme was employed, while other configurations are the same as the July episode. The hourly time series of surface wind, tem perature, and humidity are illustrated in Figure 3. The daily average performance statistics are listed along with the July ep isode in Table 4. Similar to the July episode, the wind simulation is a li ttle worse than the MM5 simulation, while the temperature and humidity simulations are bette r than MM5. The overall performance of the August episode is the worst among the three epi sodes, which is also the case of the MM5 simulations.

Performance Evaluations of CAMx and CMAQ Using WRF Meteorology

Appendix VI-iv summarizes performance eval uations of CAMx and CMAQ using WRF meteorology.

### App. VI-iv-2 Performance Evaluation of CAMx/WRF
The meteorological data derived by WRF was converted to the CAMx compatible format using the WRFCAMx preprocessor version 2. 0 provided by ENVIRO N. All parameters applied for the WRFCAMx process are the same as used in the MM5CAMx process.
The CAMx/WRF configurations are the sa me as used in the CAMx/MM5 performance evaluation. The operational statistics ofone-hour and eight-hour ozone for each episode are presented in Tables 1 and 2, respectively. The results show that the CAMx/WRF gives a satisfactory performance for the June episode, but under-predicts fo r the July and August episodes.
The accuracy of unpaired peak ozone predicti on is somewhat enhanced for the June and July episodes by the WRF meteorology, but itis deteriorated for the August episode in comparison with the CAMx/MM5 modeling. However, the otherstatistical metrics showed opposite results.
For the overall performance, the CAMx/MM5is better than the CAMx/WRF for the June and July episodes while the CAMx/WRF is better for the August 2001 episode.

### App. VI-iv-5 Performance Evaluation of CMAQ/WRF
The WRF meteorology data were converted to the CMAQ compatible data format using the EPA Models-3/Meteorology-Chemistry Interface Processor (MCIP) version 3.3. A couple of more changes in the WRF meteorology data had to be made prior to the CMAQ modeling. The first one is to change the way t he nested domains are described. The central longitudes and latitudes of nested domains for the MM5 modeling are vi rtually fixed at the parent domain center, which renders asymmetric coordinates in nested domains if their real domain centers are not coinci dent with the parent domain center. However, the central longitudes and latitudes of nested domains fo r the WRF modeling are fixed at the real domain centers, which results in symmetric coordinates. MCIP was modified to adjust the WRF nested domains to be consistent with the MM5 nested domains in order to use emissions data developed for the MM5 nested domains without any change. The other modification is to add a functi on of reading land use data from the WRF terrain file, which is required by the dry deposition al gorithm and other schemes of CMAQ.
The configurations for the CMAQ/WRF m odeling are the same as those for the CMAQ/MM5 performance evaluation (see the M odeling Protocol of Appendix I-i). The performance of CMAQ/WRF is similar to t hat of CMAQ/MM5. Tables 3 and 4 list the operational statistics of one-hourand eight-hour ozone concentrations, respectively. The performance of the CMAQ/WRF is satisfactoryfor the June episode, but under-predicts for the July and August episodes.
The performance of the CMAQ/W RF is generally better for the July and August episodes than that of the CMAQ/MM5.

### App. VI-v-1 Appendix VI-v

Maintenance Demonstration Using CAMx/WRF, CMAQ/MM5, and CMAQ/WRF

Appendix VI-v describes maintenance dem onstration results using CAMx/WRF, CMAQ/MM5, and CMAQ/WRF. The maintenance demonstration was conducted using the EPA’s Modeled Attainment Test Software (MATS, Version 2.0.1) with the minimum allowable threshold value at 70 ppb.

### App. VI-v-2 Maintenance Demonstration Using CAMx/WRF
The estimated relative response factor (RRF) and future DV for each monitoring site are listed in Table 1. The maximum future DV for monitoring sites for each episode is highlighted in bold. The maximum future DVs in unmonitored area are listed at the end of the table. As shown in Tabl e 1, the maintenance of the eight-hour ozone standard in 2025 is demonstrated with the maximum future DVs below 85 ppb for all three episodes.
The maximum future DV of the June episode for monitoring sites is 81.1 ppb with a wide margin of 4 ppb below the standard of 85 ppb. The unmonitored maximum is 80.8 ppb. The monitoring site with the maximu m future DV is North Phoenix (NP) site, which is the same site as identified by CAMx with MM5. NP is also the site with the maximum baseline DV in 2005. The difference of future DV wit h the CAMx run using MM5 meteorology is generally within ±0.5 ppb. This suggests t hat the uncertainty introduced through the meteorological input is small, which mightbe attributed to the good performance of both MM5 and WRF for this episode (see Appendix IV).
The future maximum DVs of the July and A ugust episodes are 1.7 and 3.1 ppb lower than that projected in the June epi sode, similar to the CAMx/MM5results. This is possibly caused by a different pattern of regional transport and local production of ozone in each episode. However, the difference of futu re DV between the CA Mx/MM5 and CAMx/WRF runs is as large as 1.9 ppb inthe August episode, while there is no difference in the July episode. By noting that the WRF performance was the poorest for the August episode, this result suggests that the uncertainty of CAMx is introduced through meteorological input.

### App. VI-v-4 Maintenance Demonstration Using CMAQ/MM5
The estimated RRF and future DV for each monitoring sites are listed in Table 2. The maximum future DV among monitoring sites is highlighted in bold, and the maximum projected future DV in the unmonitored area are listed at the end of th e table. As shown in Table 2, the maintenance of the eight- hour ozone standard in 2025 was confirmed by CMAQ/MM5 modeling: the future DVs ofall three episodes are below 85 ppb.
The maximum future DV of the June episode among all monitoring sites is 79.1 ppb, with a wide margin of 6 ppb below the standard of85 ppb. The unmonitored maximum is 79.3 ppb. The monitoring site with the maximum future DV is North Phoenix (NP) site, which is the same as the one identified by CAMx. T he future DVs derived byCMAQ are generally 1-2 ppb lower than those derived byCAMx, while the maximum future DV of CMAQ is 1.9 ppb lower than the CAMx. This suggests that t he uncertainty introduced by an air quality model is larger than that introduced by a meteorological model MM5 or WRF (e.g., ±0.5 ppb).
The future maximum DVs projected in the July and August episodes are 77.3 ppb and 76.6 ppb, which are 1.8 and 2.5 ppb lower than the one projected in the June episode, respectively. This is similar to the predictionsby the CAMx/MM5 run. The monitoring site with the maximum future DV shifted to the Fountain Hills (FH) site from the North Phoenix (NP) site.

### App. VI-v-6 Maintenance Demonstration Using CMAQ/WRF

The RRF and future DV for each monito ring sites derived by the CMAQ and WRF meteorology are listed in Table 3. The maintenance of the ei ght-hour ozone standard in 2025 is demonstrated with the CMAQ/WRF runs . The maximum future DV of the June episode for all monitoring sites is 79.3 ppb, wit h a wide margin of 6 ppb below the standard of 85 ppb. The maximum future DV in the unmonitored area is 78.9 ppb. The monitoring site with the maximum future DV is the NP site.
The future DV for the July episode is 1.5 ppb lower than that of the June episode, and 5.1 ppb lower than that of the August episodes due to the different pattern of regional transport and local production of ozone.

The difference of future DVs between the CM AQ/MM5 and CMAQ/WRF is relatively small, which indicates that the uncertainty introduced through the meteorologica l input is small for all three episodes.

### RESPONSES TO COMMENTS

### 1 MAG Responses to Comments on the Draft Technical Support Document for Ozone Modeling in Support of the Eight-H our Ozone Redesignation Request and Maintenance Plan for the Ma ricopa Nonattainment Area

Comments received from EPA in an email from Wienke Tax Dated November 24, 2008

Comments on Maintenance Plan in General

1. Comment: On page ES-1, first bullet under Clean Air Act requirements - it is not a requirement of the CAA for redesignation t hat we approve the June 2007 Eight Hour Ozone Attainment Plan. I would recommend deleting this bullet. (We will consider this plan when we act on the maintenance plan, but may not need to approve the entire plan in order toredesignate the area.)
Response: The bullet has been deleted.

2. Comment: Where you mention Sect ion 110, I would always add "of the Clean Air Act" to avoid confusion. It appears on page 1-5 in the fi rst full paragraph, and again on page 2-8, 3rd paragraph from the bottom. (T here are other references to Section 110 in the plan, but they in cluded "of the CAA".)
Response: These additions have been made.

3. Comment : To avoid confusion on the part of the public, I would add some text prior to Tables 2-1, 2-2, and 2- 3 explaining the 8-hour ozone standard, fourth highest high averaged over 3 years. If you don't know how the standard is calculated, it appears that 3 monitors violated in 2005 and 1 in 2006.
Response: MAG added the following text to P age 2-2 of the Ma intenance Plan: “Tables 2-1 through 2-4 show the four hi ghest eight-hour ozone concentrations at each monitor for the years 2005 through 2008, respectively. A violation of the standard occurs when the fourth-highest val ue at each monitor, averaged over three consecutive years, is0.085 ppm or higher.”
Comments on Modeling

1. Comment: The modeling analyses presented in t he draft appear to be more than adequate for support of the maintenance demonstration, and to address the expanded scope of analysis described in E PA's "Guidance on the Use of Models and Other Analyses for Demonstrating Attain ment of Air Quality Goals for Ozone, PM2.5, and Regional Haze", EPA-454/B-07-002, April 2 007. However, EPA believes the document and the maintenance demonstration could be strengthened by the inclusion of additional text relating to conclusions reached from the supplemental

### 2 analyses described in draft TSD secti ons VI-2 on Process Analysis, VI-3 "Photochemical Source Apportionment", and VI-4 "Decoupled Direct Method" (pages VI-I through VI-22, or 163-184 in PDF file). Each of th ese sections describes results of analyses that are helpful for understanding the ozone episodes modeled, and in some cases, how they are likely to respond to controls. The EPA guidance document, at section 7.0 recommends " additional analyses that.... enhance the assessment of whether the pl anned emissions reductions will result in attainment. ... States should review these supplemental analyses, in combination with the modeling analysis, in a 'weight of evidence' assess ment of whether each area is likely to achieve timely attainment." In keeping with these goals of s upplemental analyses, EPA recommends that MAG review the results of the analyses presented, and briefly summarize how each supports the results of the maintenance demonstration modeling. That is note, results that support the conclusion of continued NAAQS maintenance, and if possible, results that corroborate the qualitative features of the model's response to controlsand of the conceptual model of ozone formation in the area. This text might be added to these sections, or possibly included under Weight of Evidence.
Response: The following text has been added at the end of each analysis:
Chemical Process Analysis - “The CPA results indicate that anthropogenic emissions affected the maintenance of the eight-hour ozone standard inside and outside the urban plume in the following way: NOx em ission reductions from onroad and nonroad sources appear to contribute toa decline in ozone concentrations outside the urban plume, while VOC emission decreases from onroad and nonroad sources and NOx emission increases from point sources seemto contribute to a decline in ozone concentrations inside the urban plume.”
Photochemical Source Apportionment – “The results of the photochemical source apportionment analysis show thatthe NOx contribution tohigh ozone concentrations is greater than the VOC contribution, onroad mobile sources are the major contributor among anthropogenic emission sources, and t he impact of both local and boundary emissions on loca l ozone concentrations is substantial. Therefore, NOx control outside the urban plume, onroad emission cont rols, and the implementation of federal, state, and loca l government emission contro l programs all contribute to maintaining the eight-hour ozone standard in 2025.”
Decoupled Direct Model – “The DDM analysis reveals that the ozone formation over the MNA is significantly influenced by t he boundary condition transported from the north side in the June episode. This result supports that ant hropogenic VOC and NOx emission reductions atthe boundaries contributed tothe maintenance of the eight-hour ozone standard in 2025.”

### 3 2. Comment: An additional minor point is that draft TSD section VI-2 (page VI-3, or 165 in PDF file) describing Ch emical Process Analysis (CPA) is labeled "indicator species". As used in EPA guidance the docum ent and elsewhere, thisterm refers to measured species, rather than modeled. In the absence of modeling, or for comparison with modeling, such ratios can indicate the degree to which ozone formation is NOx-limited or NOx-saturated. Since this is not the type of analysis described in this section, EPA suggests a ti tle of "Process Analysis" or something comparable. A similar comment would apply to most other uses of "indicator species" in the document.
Response: This correction has been made.

### 4 Comments received from the Arizona Depart ment of Environmental Quality in a letter from Steven E. Peplau dated November 25, 2008

Emissions

1. Comment: In the 2005 modeling, the onroad NOx emissions showed a decrease of 9% from June to August (2005), and in the 2025 modeling, t he onroad emissions showed a decrease of 5% from June toAugust (2025). One would expect the summer traffic numbers to be so mewhat constant from June to August, as shown by the onroad VOC emissions for t he same three-month period. This expectation is also reflected in the modeled VOC emissions, which increased by 1% from June to August (2005), and increased by 2% from June to August (2025). Please explain why NOx is decreasing for the time periods.
Response: Both temperature and humidity affe ct onroad VOC and NOx emissions. When the temperature is higher, more VOC evaporation occurs, while higher humidity lowers NOx emissions (ENV IRON, 2003). MAG employed day-specific temperature and relative humidity to run MOBILE6 in developing the daily onroad emissions. Temperature and relative humidity in August are generally higher than those in June. For example, the maximum temperature and relative humidity at the Supersite were 91.0 F and 51.1% on June 3, 2005, and 103.5 F and 61.4% on August 6, 2005. Therefore, higher temperature and relative humidity on August 6, 2005 contributed to higher evaporative VOC emissions and lower NOx emissions in comparison with those em issions on June 3, 2005.

2. Comment: We have compared the current docum ent with MAG’s previous Ozone Study “Eight-Hour Ozone Plan for the Maricopa Nonattain ment Area” (June 2007) and have found several important differences:
The emission ranges for the June 2007 report graphs (August 24, 1999) and the November 2008 report graphs (June, July and August 2005) are listed below. It would be helpful if the ranges coul d be standardized for these cases.

### 5 Response: MAG provided emission density plots fo r August 24, 1999 in the OneHour Ozone Maintenance Plan (March 2004), for the August 2001 and June and July 2002 episodes in the Eight-Hour Ozone Plan (June 2007), and for the June, July, and August 2005 episodes in the Eight-Hour Ozone Maintenance Plan (November 2008). These emission density plots were presented to verify the robustness and accuracy of th e spatial allocation of em issions, to identify the locations of high emissions, and to investigate the spatial relationship between emissions and ozone predictions. Consistent ranges for the emission density plots were used in the spatial comparison of the baseline and future year emissions in each plan. However, the application of t he same emission ranges to the emission density plots across different ozone plans and years levels out the distinctive spatial emission distributions of sources which are typical of each plan. This is the reason that the same emission ranges were not used for the emission density plots in the different ozone plans.

3. Comment: In the Base Case (August 24, 1999) MAG provides graphs for Onroad (VOC and NOx) and Background (VOC and NOx), while in the current document (Nov 2008) there are three graphs for On road (VOC and NOx), Anthropogenic (VOC and NOx), and a third category ofall sources (VOC and NOx).
Response: In developing the 8-hour ozone attainment and maintenance plans (June 2007 and November 2008), it was found t hat the emission density plots for the Background category were oflimited use because the Background category includes emissions from point, area, and nonroad sources, but not onroad and biogenic sources. The emission density plots for the Background category were replaced with emissions density plots fo r the Anthropogenic category (all man-made source emissions such as point, area, onroad, and nonroad sources, but not biogenic sources) and the All Sources category (a ll emission sources including biogenic sources) because comparison of the emission density plots for these two categories allows the impact of biogeni c sources to be evaluated.

4. Comment: The lack of consistency between the two modeled years, 1999 and 2008, reduces the ability to show the trends inOzone precursors (VOC and NOx) between modeling years or to make any significant conclusions concerning Ozone hot spots. It definitely reduces the usefulness of the emission inventory and modeling data.
Response: MAG conducted the one-hour ozone maintenance modeling demonstration for the August episode of 1999 (e.g., August 24, 1999), while the eight-hour ozone maintenance modeling demonstration was based on baseline (2005) and future (2025) year emissi ons. The eight-hour ozone maintenance modeling performed in 2008 is different from the one-hour ozone maintenance modeling conducted in 2004 in terms of models (e.g., MAGBEIS2 vs. MEGAN, EPS2 vs. EPS3, UAM-IV vs. CAMx, etc.), assumptions, input data, modeling domain, EPA modeling guidelines, etc. For example, the latest biogenic models (e.g., MEGAN or GloBEIS) estimate substantia lly higher VOC emissions than the older version of biogenic models (e.g., MAGBEIS2or BEIS2). Therefore, ozone precursor

### 6 emissions developed with different versions of models orinput data may not show any consistent emission trends between m odeling years due to the aforementioned differences.

MOBILE6 Modeling

1. Comment: MAG used MOBILE6 default diesel fractions, documented in a MOBILE6 technical document written in 2001 (FleetCharacterization Date for MOBILE6: Development and Use of Age Distributio n, Average Annual M ileage Accumulation Rates, and Projected Vehicle Counts for Use in MOBILE6, EPA, September 2001). Those numbers were derived from a studyconducted in 1996. The 1996 data seems outdated. ADEQ suggests t he ADOT local registrati on data be compared with the MOBILE6 defaults as a check on the valid ity of this set of assumptions.
Response: MAG did test locality-specific dieselfractions derived from the vehicle registration data of Maricopa County for MOBILE6 runs. Use of these diesel fractions derived from the local registrati on data resulted in an extraordinarily high VMT distribution of Light Duty Diesel Vehi cles (LDDVs) and Light Duty Diesel Trucks (LDDTs) on highways and arterials. For example, in January 2008, the vehicle registration data for Maricopa County indicate a total of 53,795 vehicles registered as LDDVs and LDDTs, and 59,540 vehicles registered as Heavy Duty Diesel Vehicles (HDDVs). Using the diesel fracti ons derived from the vehicle registration data for Maricopa County resulted in a 22 % VMT distribution of LDDVs and LDDTs on freeways and arterials. In comparison, the MOBILE6 default diesel fractions provide only a 2% VMT distribution ofLDDVs and LDDTs to the total VMT distribution of diesel vehicles. This is the reason that MAG used the national diesel fraction data, provided as the default valuesin MOBILE6, instead of local diesel fraction data, which was highly unrealistic.

2. Comment: For committed measure #2, MAG s howed a table demonstrating the cut points for LDGV, LDGT1 and LDGT2 (App. IV-xv-5). According to VEI, the cut points shown in this table are act ually for LDGV, LDGT1+LDGT2, and LDGT3+LDGT4. MAG also mentioned that LD GV cut points were used in block 1, LDGT1 in block 2 and LDGT2 in block 3. However, MOBILE6's definition of vehicle blocks is different from AD EQ. MOBILE6 requires the cut points of LDGV and LDGT1 in block 1, those of LDGT2 and LD GT3 in block2, and those of LDGT4 in block 4. EPA suggested multiple runs to be performed and results merged to solve this problem.
Response: Since MOBILE6 does not simulate Arizona’s IM147 test, ADEQ provided the methodology to model the IM147 testusing the IM240 prog ram parameters of MOBILE6 in ADEQ’s memorandum to MAG on May 28, 2001. The cutpoints described on App. IV-xv-5 are based on the me mo and cutpoint file ADEQ provided. The memo indicated that "IM147 test went into effect in Maricopa County in January 2000. Research conducted to develop the test, however, shows that the IM147 test

### 7 has nearly the same ability to identify excess emissions as the IM240 test. The IM147 test provides 97.9% of the benefit of the IM240 test with final cutpoints for CO, 85.6% for HC, and 77.5% for NOx. The MOBILE6 Users Guide states that four blocks of 75 cutpoints are required. Note that there is not test ing of heavy-duty gas vehicles in IM147; these v ehicles are only required totake a loaded/idle and antitampering test. Consequently, the values ent ered in this fourth block are of no consequence. The third block - for light-dut y gas trucks #4 - can take its cutpoints from the LDGT2 of the attached table. The first and second blocks, however, are impossible to map accurately into the cutpoi nts now in effect. The first block requires a single set of cutpoints for both light-duty gas vehicles and light-duty truck #1, but the cutpoints of the present IM147 treat these two gr oups separately. I would recommend that the first block take its values from the LDGV cutpoints and the second block from the LDGT1 cutpoints.” If the instructions inADEQ’s memo are no longer valid, please provide MAG with I/M cutpoint data and an official memo which describes the new modeling methodology for IM147. The new methodology will be used in future ozone modeling.

Photochemical Modeling
Modeled Episodes

1. Comment: The EPA Guidance on the Use of Models and Other Analyses for Demonstrating Attainment of Air Quality Goals for Ozone, PM2.5 and Regional Haze (EPA Guidance) (EPA, 2007) recommends t hat “at a minimum...modeling ‘longer’ episodes that encompass full synoptic cycles. Time periods which include a ramp-up to a high ozone period and a ramp-down tocleaner conditions allow for a more complete evaluation of model perform ance under a variety of meteorological conditions (Page 140).” This recommendation is intended to improve the modeling performance evaluation for ozone modeling. It seems that none ofthe three ozone episodes include a complete synoptic cycl e, and no ramp-down days were modeled.
The current modeling performance evaluati on shows that the m odel consistently underestimated ozone concentrations when local production plays a major role. This indicates systematic deficiencies in t he modeling system, possibly due to the meteorological modeling or the transport modelin g, or both. Therefore, including ramp-down days in the modeling may hel p to diagnose the underestimated ozone concentrations, since the ramp-down days may represent a shift in the meteorological system or in a chemical processes. Please clarify whether MAG has looked at modeling perform ance or plan to further evaluate modeling performance during ramp-down days.
Response: The three ozone episodes used for the model performance evaluation were selected through extensive research of the data for the five ozone seasons (2000 to 2004) by following EPA’s modeling guidance (See Attachments II and III of the Eight-Hour Ozone Plan). ENVIRO N conducted numerous MM5 modeling

### 8 analyses with observed meteorology to derive the best meteorological data for CAMx modeling for the three episodes (S ee Appendix III of the Eight-Hour Ozone Plan). In addition, the three ozone episodes reflect ramp-up and ramp-down conditions of monitoring sites. Since EPA approved the three ozone episodes for use in the eight-hour ozone maintenance de monstration, new analyses will not be conducted to revise the three episodes oradd more ramp-down days in the EightHour Ozone Maintenance Plan. However, MAG will consider ADEQ’s suggestion in the development of future attainment ormaintenance plans for the 2008 eight-hour ozone standard of 0.075 ppm.

Modeling Performance Eval uation (MPE) Statistics

1. Comment: The EPA Guidance suggests that “as appropriate, States/Tribes should aggregate the raw statistical results into meaningful groups of sub-regions or subperiods (page 199).” MAG conducted MPE for all monitors as a whole; however, more detailed examination of these sites indicates that they could well fell into at least two subgroups: (a) urban Phoenix sites, and (b) “suburban or more distant sites”.

Table V-1 shows that almost all of the ozone monitors t hat show the highest design values (ranked 1 through 7) are located outside the Phoenix urban area, except for the North Phoenix site (ranked 1). When further compared with Figure III-1 (CPA results), we see that all of these sites (except for North Phoenix) are at the edge or completely outside of the urban plume, such as Humbol dt Mountain, Tonto and Rio Verde. The diurnal variations of ozone at thes e sites are also distinctly different from those at the Phoenix urban area: (1) the diurnal variat ion is much weaker, and (2) nighttime ozone concentrations are much hi gher (are above 50 ppb at some sites) (MAG Office Memorandumfrom Huiyan Yang etc. on February 22, 2008), included in Appendix I/Attachment III) . These differences suggestthat the ozone cycles at these two groups of sites are controlled by different factors. During high ozone days, the urban Phoenix sites are likely to be contro lled more by local production, while the “suburban sites” are likely to be contro lled by background ozone in addition to weaker ozone production.
ADEQ suggests examining the monitoring si tes and grouping them according to their characteristics and then applying MPE to each subgroup. This may help to identify the strength and weakness of th e modeling for a variety of processes contributing to peak ozone. Evaluations of this nature may be helpful with the future ozone plan for the new lower standard. This would be particularly useful, since the more distant sites such as Humboldt Mountain and Rio Verde are often reco rding higher ozone values than the urban sites, indicating the elevated contribution of background
ozone.

### 9 Response: MAG conducted additional MPE fo r two subgroups (urban and suburban sites) for each episode. The new MPE results by subgroup are provided in Appendix III-i

Chemical Process Analysis (CPA)

1. Comment: A CPA was only conducted for the June 2002 episode. This is an episode dominated by transport; however, one of the primary goal s of CPA is to identify the strength and cont rolling species for photochemical ozone formation. It may be more appropriate to conduct CPA for the July 2002 episode when local ozone formation is the dominant contributor . Please explain why CPA results are shown for noon time if ozone peak concentrati ons often occur in middle to late afternoon.
Response: MAG conducted additional CPAs for the July and August episodes and these results are provided inAppendix VI-ii. CPA results are shown for noon time because modeled ozone production rates were high in many areas at noon.

Modeled Ozone Spatial Distribution

1. Comment: The “Absolute Model Forecasts” in Section VI tabulated the modeled highest grid ozone concentrations. A contou r map of future ozone generated by the MATS is also presented later in the TSD. In addition, MAG should provide modeled gridded ozone concentration maps for the bas eline and future years. These maps will provide a clear visual ization of the ozone distri bution under the baseline and future conditions, identifying any “hot s pots” and showing the “improvement area”. Although the absolute modeled level of ozone should not be deemed as representative for actual ozone distribution, the model does provide a fairly accurate representation of the spat ial distribution (high vs. low areas). For a better understanding of the ozone cycle, MAG may also want to provide gridded ozone maps for the nighttime.
Response: Maximum and minimum modeled ozone tile plots for each episode of the baseline and future years are provided in Appendix VI-i.

Underestimating Ozone

1. Comment: The statistical MPE results show t hat CAMx consistently underestimates peak ozone when local production plays a major role (July 2002 and August 2001 episodes). Results for two of the th ree episodes are outside of the EPA recommended range. ADEQ suggests that MAG compare its modeling work other similar modeling work to try to determi ne why MAG’s modeling often under-predicts
ozone.

### 10 Response: MAG had performed an extensive number of CAMx/MM5 simulations, with assistance of ENVIRON, to derive the best CAMx/MM5 model performance for the three episodes, as shown in the 2007 Eight-Hour Ozone Plan. In addition, numerous model performance tests, with diffe rent combinations of air quality and meteorological models (e.g., CAMx /MM5, CAMx/WRF, CMAQ/MM5, and CMAQ/WRF) were carried out in the 2008 Eight-Hour Ozone Maintenance Plan to find uncertainty in model performance. These results indicate that the performance of different air quality and meteorological models are similar to the performance of CAMx/MM5.
Numerous air quality studies have co mpared measured and simulated ozone concentrations: under-predictions of ozone have been commonly reported in these studies (Jinyou Liang, 2004). Gopal Sistla, et al. (Gopal Sistla, 2001) suggested the need for improvement in the treatment of th e physical and chemicalprocesses of the air quality modeling system to improve the model performance. A number of studies have suggested the improvem ent in the emissions and meteorological modeling system as well (Jhumoor Biswas, 2001). Steven Reynolds, et al. (Steven Reynolds, 2003) pointed out that developi ng all required inputs to the model with sufficient accuracy is a challenge. EPA modeling guidance (EPA, 2007) also indicates that model estimates will not perfectly predict the observed air quality due to uncertainty in meteorological or other input data base limitations and/or an incomplete representation of the model’s physiochemical processes.
MAG continues to strive to improve m odel performance for on-going and future air quality modeling. Specific technical suggestions for this purpose will be welcomed.

Sensitivity Tests

1. Comment: One conclusion of the modeling analysi s is that “the region of greatest ozone production in the urbanplume are VOC-sensitive”, meaning that adding VOCs will result in an ozone increase and reducing VOCs will result in an ozone decrease (Page III-23). The Decoupled Direct Method results, in contrast, show that when zeroing-out (reducing to zero) Ma ricopa County biogenic emissions (mainly VOCs), ozone concentration would be increased (as shown in Figure VI-8 (a)). DDM results also shown that zeroing out Ma ricopa County onroad emissions (mainly NOx) resulted in lower ozone concentrations in the northern Phoenix area (blue areas in Figure VI-8 (b)). These results seem to contradict to the abovementioned conclusion. Please clarify how VOC and NOx emissions are expected to impact ozone formation in the urban Phoeni x area. Also, considering t he non-linearity between ozone precursors (VOC and NOx) and ozone formation, it may not be appropriate to zeroout emissions. It may be more reasonable toscale down emission s, rather than zeroing out emissions, for m odeling sensitivity tests.
Response: The ozone sensitivity plots from the Decoupled Direct Method results, shown in Figures VI-7 through VI-12, indicate that ozone concentrations are

### 11 equivalent to the subtraction of zeroing-out results from future yearresults. Positive values in these plots mean that ozone concentrations decrease when certain emission sources are removed (zeroed-out). Therefore, th is conclusion agrees with the DDM results.

### 12 Comment received from Jo Crumbakerof Maricopa County Air Quality Department dated November 12, 2008

1. Comment: Jo Crumbaker asked about the locati ons of the maximum future design values obtained from the unmonitored area analysis at the Air Quality Planning Team meeting.
Response: The following email was sent to Jo on November 12, 2008.

______________________________________________ From: Taejoo Shin Sent: Wednesday, November 12, 2008 5:03 PM To: Jo Crumbaker - AQDX Subject: Your question on the locations of the maximum future design values for unmonitored area... Hi Jo,
For your question at the Air Qua lity Planning Team meeting, we have investigated the unmonitored locations which have the 2025 peak design values.
The unmonitored locations of the peak design values are:
The June episode: 81 ppb of the maximum 2025 design value was located around the north-east boundary of Maricopa County (Tonto National Forest).
The July and August episodes: 79 ppb for the July episode and 83 ppb for the August episode was located in the area between North Phoenix and Pinnacle Peak monitoring sites.

MS. BAUER: This public hearing is being

held jointly with the Arizona Department of Environmental
Quality and the Maricopa Association of Governments to

receive public comments on the draft MAG Eight-Hour Ozone
Redesignation Request and Maintenance Plan for the
Maricopa Nonattainment Area. Those who are in the

audience who parked in the garage can have their tickets

validated by the MAG staff.

The public hearing this evening will begin with

some introductory remarks from one of the members of the

audience who has submitted a slip in order to make some

remarks. Ms. Dianne Barker has requested an opportunity

to present some public comments before we give the**presentat~on** this evening due to a commitment to a meeting that Ms. Barker has. So at this point in time I

would like to ask Ms. Barker to come and give her

comments. Thank you very much.

MS. BARKER: Thank you, Ms. Bauer, and MAG.
My name is Dianne Barker. I'm at 3219 East Camelback
Road, Number 393, in Phoenix, 85018. live lived in the
Valley for 23 years. I did come down here today by the

natural gas bus and the light rail system and I'll be

headed to Tempe on that light rail and use the bus and I

also have a little folding bicycle. I add that just to

let you know that I do do part of that not only for

### Page 4 expediency to get around downtown, but I have personal
goals in regards to cleaner air and I db believe those

activities add to that.

After reading some of your materials in the
library explicitly December 2008 Draft Eight-Hour Ozone

on page 213, I have a concern and it's in regards to fuel

which is one of the main sources of your contingent of

your measures for control for the eight-hour plan. It

says in quote: IIMVTB has been the primary oxygenate used

in Arizona. II And this is because they claim there was difficulty in blending ethanol. I've long time had a

concern about MVTB. Others may have heard about some of

the problems of it getting into the ground. I am not an
expert on that fuel; however, in 1988 I was on a Valley

Citizens Committee. I submitted that using alternative

fuels can add to carcinogens and major pollutants that

are of concern and can hurt people. So I submit that to

you. I think we need to have further study.

I'm also submitting an article today about how

cleaner air

-- it's one of the first studies by EPA

funded

-- does create longer lives. But Phoenix isn't

mentioned in here, so I have a concern for them looking

into this area and seeing what we're doing and if the

measures are helping. They don't explicitly talk about

the Eight-Hour Ozone, but they talk about air pollution

and the particulates in that.

And the other thing in your draft plan that I am

concerned about is as you used a contingency provision

page 322 on the same document that I have spoken on and

we know that after we reach .084 parts per million and

any monitor there is a violation. I will sum this up.

This is an IT contingency provision. I'd like to see if

in fact the IT we're using on the light rail and the

other ITs for traffic are helping, do they help more, or

do we need to look at that on a caution basis.

So thank you for your time and have a happy new

year.

MS. BAUER: Thank you very much,

Ms. Barker.

Now we'll return to the normal order of our public hearing process. We're glad we were able to

accommodate you. The public hearing will begin with some introductory remarks. We wanted to ask DEQ if they would

like to offer any remarks at this time.

MS. ARNST: We don't have any remarks at

this time.

MS. BAUER: Thank you very much. We'll

have an overview presentation by the MAG staff.

of the hearing. Written comments are also welcome this
evening.

For those participants wishing to speak, please

fill out a form on the table and place it in the box. If

you need to speak early, just let us know and we will

accommodate you. As you come up to the podium, please

state some information for the formal record: your name

the red light will come on.

So now I will give a presentation on the
Eight-Hour Ozone Redesignation Request and Maintenance

Plan.

Thank you very much. My name is Lindy Bauer and

I'm with the Maricopa Association of Governments. And,
again, I welcome you to the hearing. Ground level ozone

is a summertime air pollution problem. Ozone is formed
by a chemical reaction that occurs between volatile
organic compounds and nitrogen oxides in the presence of
sunlight. You need very warm temperatures and minimal

wind for ozone to form. In general, motor vehicle

emissions, industrial emissions, gasoline vapors,

chemical solvents, and even natural vegetation, such as plants, trees can also contribute to ozone formation.

In 1997, the Environmental Protection Agency

established an eight-hour ozone standard of .08 parts per

million. The Maricopa nonattainment area was designated

as a nonattainment area for this pollutant at that

concentration in 2004. And you'll see the nonattainment

area boundary in green. Collectively the nonattainment

area boundary represents approximately 4,880 square

miles. It includes portions mostly in Maricopa County

and Apache Junction in Pinal County. 

# 7 Now over time there has been significant

progress made to reduce ozone in the MAG region and in

this nonattainment area. This bar chart indicates that

there have been no violations of this eight-hour ozone

standard since the year 2004. So this has been due to

the measures that have been implemented over time by the

state, the local governments, and Maricopa County, and

the private sector.

Since there have been no violations for several

years of this standard, the Maricopa Association of

Governments is now officially requesting that this region

be redesignated to attainment status. There are basically four steps to redesignation to attainment.

### Page 8
First, EPA determines that the standard has been

met. And this is as measured at the monitors. Secondly,

EPA has to determine that the air quality improvement is

due to permanent and enforceable reductions in emissions.

Third, EPA has to determine that the state has met the

Clean Air Act requirements for plans. And lastly EPA has

to take approval action on the maintenance plan. Now the

maintenance plan demonstrates that the eight-hour ozone

standard will continue to be met through 2025 with
existing measures that are already in place.

In order to reduce ozone, we focus on reducing

volatile organic compound emissions and also nitrogen

oxide emissions. Now this chart indicates the measures

and their impact that we are using for the maintenance

demonstration showing that this region will continue to

meet the eight-hour ozone standard through the year 2025.

So these are the variety of measures that we

have in place. Most of them have to do with motor

vehicles. We have summertime fuel reformulation. We

also have the federal nonroad emissions standards which

are designed to reduce emissions from equipment along the
roadways. We have improvements to the vehicle emissions
testing program. And we have banned open burning during

the ozone season because even though there is some burning going on during the ozone season, this can be a

problem, so this is another measure in the plan. And as

I mentioned, most of these have an impact on the motor

vehicle.

This is another measure that I would like to
explain. Expansion of Area A. Now this was in
legislation passed by the legislature in 2001. Area A
applies to portions of Maricopa and Pinal and Yavapai

Counties and the thinking of the legislature was to
incrementally over time add measures to Area A in order

to prevent violations of the ozone standard and the other
pollutants.

Now I'd like to turn to the impacts of those

same measures on nitrogen oxides. You can see the impact

of the measures. They are in slightly different order

because they have a little bit different impact on nitrogen oxides than they do on volatile organic
compounds. And these are the impacts in both slides on

man-made emissions.

Next I would like to show you some pie charts to

show 

### you that in the maintenance year 2025 what the

distribution of emissions looks like by source. Often

we're asked in the maintenance year or in the attainment

year do we still have sources and emissions, and the

answer is yes, but in those years we are predicting that

we will still be maintaining the standard. So you can

see the distribution for 2025 for VOC emissions with

measures in place.

The next pie chart is the impact of the measures

on the sources in the year 2025 only this time taking a

look at reductions in nitrogen oxides. In this plan we

also have contingency measures. These are measures above

and beyond the measures that we're using to demonstrate

maintenance of the standard in 2025. These measures are going to be implemented and have been implemented right
along with the regular maintenance plan measures. Generally the approach taken in this

nonattainment area has been to implement contingency

measures along with plan measures that's your best chance

of success from preventing violations. Most of these

measures are improvements to the component of the vehicle

emission and inspection program. There are some measures

here for coordinating traffic signals and developing
intelligent transportation systems. This maintenance
plan also establishes a budget for motor vehicles.



### Under the Clean Air Act there are requirements

for transportation conformity. The air quality plans
actually set motor vehicle emission budgets. Under the

Clean Air Act this is a requirement to prevent
transportation plans, programs, and projects from causing

air quality violations.

So in this maintenance plan there is a new budget for volatile organic compounds of 43.8 metric tons

per day and a budget for nitrogen oxides 101.8 metric

tons per day. Now these new budgets will be used in the
conformity analyses after they are found to be adequate

or they are approved in the plan by the Environmental

Protection Agency.

The schedule for the eight-hour plan is as

follows: The document was available for public review on

December 23rd, 2008. Tonight is the public hearing. The

MAG Air Quality Technical Advisory Committee is scheduled

to meet on January 26, 2009. And at that time the

committee will be reviewing comments made and a response

to comments. And then it is anticipated they may make a

recommendation on the plan. Their recommendation would

go to the MAG Management Committee on February 11th,

2009. And then it would go to the MAG Regional Counsel

for action on February 25, 2009. MAG would then provide

the plan to the Arizona Department of Environmental
Quality. And at the end of February the Arizona
Department of Environmental Quality anticipates
submitting the plan to the Environmental Protection
Agency.

Now once this plans goes into EPA, MAG will
begin working on the planning effort for the new

### RESPONSE TO PUBLIC COMMENTS ON THE DRAFT MAG EIGHT-HOUR OZONE REDESIGNATION REQUEST AND MAINTENANCE PLAN FOR THE MARICOPA NONATTAINMENT AREA

JANUARY 22,2009 PUBLIC HEARING

The Maricopa Association of Governments (MAG) appreciates the comments made during the public comment period for the Draft MAG Eight-Hour Ozone Redesignation Request and Maintenance Plan for the Maricopa Nonattainment Area. An advertised public hearing
was held on January 22,2009. Verbal testimony was presented at the public hearing. No written comments were received during the comment period. The following represents the MAG response to the comments received.

COMMENTS FROM DIANNE BARKER (Testimony attheJanuary22, 2009 public hearing)

Comment: I've lived in the Valley for 23 years. I did come down here today by the natural gas bus and the light rail system and I'll be headed to Tempe on that light rail and use the bus and I also have a little folding bicycle. I add that just to let you know that I do part of that not only for expediency to get around downtown, but I have personal goals in regards to cleaner air and I do believe those activities add to that.
Response: The Maricopa Association of Governments appreciates the efforts Ms. Barker is making to improve air quality by using alternative modes such as light rail, buses, and bicycles.

Comment: After reading some of your materials in the library, explicitly December 2008 Draft Eight-Hour Ozone on page 2-13, I have a concern and it's in regards to fuel, which is one of the main sources of your measures for control for the eight-hour plan. It says "MTBE has been the primary oxygenate used in Arizona." And this is because they claim there was difficulty in blending ethanol. I've long time had a concern about MTBE. Others may have heard about some of the problems of it getting into the ground. I am not an expert on that fuel; however, in 1988 I was on a Valley Citizens Committee. I submitted that using alternative fuels can add to carcinogens and major pollutants that are of concern and can hurt people. So I submit that to you. I think we need to have further study.
Response: The paragraph on page 2-13 of the Draft Eight-Hour Ozone Redesignation Request and Maintenance Plan that refers to methyl tertiary butyl ether (MTBE) states: "On April 28, 2000, Senate Bill 1504 was signed into law by the Governor of Arizona. The law revised A.R.S. Section 41-2124 by eliminating the maximum oxygenate requirement for summertime gasoline in Maricopa County. Because of the cost and difficulty of blending ethanol in CBG and meeting the 7.0 psi Reid Vapor Pressure standard, MTBE has been the primary oxygenate used in Arizona's summertime CBG."

This text indicates that Senate Bill 1504 eliminated the need to use MTBE in summertime cleaner burning gasoline (CBG) in Maricopa County. However, to make it clearer that the oxygenation of Maricopa County summertime gasoline has not been required since 2000,

### the verb in the last sentence has been changed from "has" to "had."
Although the text states that Senate Bill 1504 eliminated the "maximum" oxygenate requirement for summertime gasoline, this is not correct; the Bill eliminated the "minimum" oxygenate requirement. So this correction has also been made to the document.

Comment: I'm also submitting an article today about how cleaner air

- it's one of the first studies by EPA funded

- does create longer lives. But Phoenix isn't mentioned in here, so I have a concern for them looking into this a.rea and seeing what we're doing and if the
measures are helping. They don't explicitly talk about the eight-hour ozone, but they talk about air pollution and the particulates in that.
Response: The air quality monitors located in Phoenix and the surrounding areas of Maricopa County indicate that measured concentrations of carbon monoxide, ozone and particulate pollution are declining over time. Since the air quality is improving at the same time the regional population, employment and vehicle travel continue to grow, it is evident that the numerous federal, state and local control measures that have been implemented in the Maricopa area have been successful in decreasing air pollution.

Comment: And the other thing in your draft plan that I am concerned about is as you used
a contingency provision on page 3-22 of the same document that I have spoken on and
we know that after we reach 0.084 parts per million and any monitor there is a violation. I will sum this up. This is an IT contingency provision. I'd like to see if in fact the IT we're using on the light rail and the other ITs for traffic are helping, do they help more, or do we need to look at that on a caution basis.
Response: "Develop Intelligent Transportation Systems" is one of the six contingency
measures identified on page 3-22 of the Draft Eight-Hour Ozone Redesignation Request and Maintenance Plan. Section VI-7-2 of the Technical Support Document describes this
measure as follows: "Nearly all of the local jurisdictions are planning and implementing advanced technology based solutions to address complex traffic management issues on the regional transportation network. These technologies involve the application of electronics, telecommunications and sensor technologies and are collectively referred to
as Intelligent Transportation Systems (ITS). This measure reduces VOC and NOx emissions by increasing vehicle speeds and reducing congestion."
"Develop Intelligent Transportation Systems," as well as the other five contingency
measures in the Draft Eight-Hour Ozone Redesignation Request and Maintenance Plan, have already been implemented in the Maricopa area. While no credit for these contingency measures has been taken in modeling maintenance of the eight-hour ozone standard, early implementation of these measures provides additional confidence that the standard will be maintained through 2025. If any air quality monitor records a violation of the eight-hour ozone standard of 0.08 ppm after EPA redesignates the Maricopa area to attainment, page 3-22 of the draft document states that "additional control measure will be considered, which may include the strengthening of existing contingency measures".
