DearMr. Vickery:

Overthe past year, the U.S. Environmental Protection Agency (EPA) Region 6 and the Texas Commission on Environmental Quality (TCEQ) have been in discussions concerningthe requirements ofTCEQ's Annual MonitoringNetworkPlan. These efforts have led to abetter understanding ofthe issues facing the TCEQ airmonitoringnetwork, and while progress has beenmade, several networkdesign issues still require attention.

On June 30, 2010, TCEQ submitted its 2010 Annual Air MonitoringNetworkPlan for

our review and considerationfor approval. EPA has completedits analysis ofthe TCEQ 2010 Annual MonitoringNetworkPlan to ensure it meets those requirements of40 CFRPart 58 and its appendices that confer approval authority on the Regional Administrator. EPA generally approves yournetworkplan, in accordance with 40 CFR §58.10 and §58.14. However, this approval is based on the expectationthat TCEQ will resolve the issues identifiedin the enclosure before the submittal ofthe 2011 networkplan. The abilityofEPA to approve TCEQ's 2011 networkplan depends on the resolution ofthese issues, which include network changes needed to meet the regulatoryrequirements forPM2.s, lead and ozone air monitoring for National AmbientAir Quality Standards (NAAQS); systemrequirements for the National Core (NCore) Network; TCEQ certification ofall 2009 data and submittal ofdata for the first two quarters of 2010; and confirmation on TCEQ's positionregardingthe 31 airmonitoring sites discussed duringthe Technical Systems Audit.

The network assessmentprocess presents an opportunityfor EPA and TCEQ to collaborate on network design issues in accordancewith 40 CFR Part 58 App. D, 1.1.2. During discussions with your staff, EPA outlinedthe schedule ofdeadlines identifiedin the enclosure. These deadlines were established in order to ensure timelyresolution ofthe enclosed issues beforethe submittal ofthe 2011 Annual NetworkPlan. Please submit aresponse by March 31, 20II,·explaininghow TCEQ has addressed each issue.
Additionally, in accordance with 40 CFR Part 58 App. D, 4.5(a)(ii), EPA approves your source-orientedlead monitoringrequirement waiverrequests for the Red RiverArmyDepot (near Texarkana), the Ft. Hood facility (nearKilleen), and Oxbow Calcining (in Port Arthur). Approved lead monitoring waivers are required to be renewed once everyfive years as part of the network assessmentrequired under 40 CFR §58.1O(

# 1. ParticulateMatter
During our review, we discoveredthatthe PM2.5 State and Local Air Monitoring Sites (SLAMS) monitors at the South Padre Island site (48-061-2004) and the Bayway Drive site in Baytown(48-201-0058) are operating at a l-in-6 day monitoring schedule. All SLAMS monitors, ifcollocated continuous samplers are notpresent, must run on at least a l-in-3 day schedule. (See 40 CFR §58.l2(d).) These monitors apparently do not conformto the monitoring schedulerequirements of40 CFR §58.l2. We note thatRegion 6, U.S. Environmental ProtectionAgency (EPA) has not received nor approved any operational exemptionrequests for sampling frequency for these monitoring sites. Accordingly, we requestthe l-in-3 day schedule be applied to these monitors, and Texas Commission ofEnvironmental Quality (TCEQ) must state that it is meetingthis schedule in the writtenresponse due March 31, 2011.

We have evaluatedyour requests for discontinuation ofthirteenPM2.5 monitors from your operating networkin accordance withthe criteriaat 40 CFR §58.14(c). Basedon current designvalues, we do not objectto your proposals to discontinue 10ofthe 13 SLAMS monitors identifiedin AppendixA ofyour 2010 Annual MonitoringNetworkPlan. However, for the

reasons discussedbelow, EPA cannot approve your requests as proposed withrespectto the following three SLAMS monitors:

A. Fort WorthNorthwest (FRM) (48-439-1002): The requested discontinuationofthis monitor would leave the FortWorth-Arlington MetropolitanDivision, an area consisting ofapproximatelytwo millionpeople, withonly one remaining monitor. Ifthe site were decommissioned as proposed, it would leave only the Congress Street site (48-439-1006) monitorto compare with the National AmbientAir Quality Standards (NAAQS) for PM2.5. One monitordoes not provide sufficientmonitoring coverage for such a highly populated area. (See 40 CFRPart 58, App. D, 4.7.1.) In orderto continue ensuring TCEQ's 2011 networkplanwill meet the requirements, we requestthatyou affirm your continued reliance on this monitororprovide us withaplanfor aproposed new site to supportthe discontinuation ofthis monitoring site by March 31, 2011.

B. San Antonio Calaveras (FRM, Site J.D. 48-029-0059): The requested discontinuation of this monitor would leave the area withonly one remaining monitor. According to the latest available census figures, the monitoris located in a metropolitan statistical area (MSA) required to have a minimum oftwo PM2.5 FRM monitoring sites. This analysis is basedon the 2008-2009 designvalue estimate of22.4 

# ug/rrr' for this MSA, the population estimates from the 2009 U.S. Census, and 40 CFRPart 58 App. D 4.7.1 Table D-5. Weunderstandthis MSA currentlyhas the minimumnumber ofmonitors necessary to meet regulatory requirements, i.e., two monitors, and the discontinuationofthe requestedmonitorwould leave the area with only one monitor. (See 40 CFR Part 58, App. D, 4.7.1.) In order to continue ensuring TCEQ's 2011 networkplan will meet the

. requirements, we requestthatyou affirmyour continuedreliance on this monitoror



# 1

# provide us with aplan for aproposednew siteto supportthe discontinuationofthis monitorby March 31, 2011.

Additionally, we discoveredthatthe PM2.5 networkfor this MSA does not comply with the collocationrequirements in AppendixA of40 CFRPart 58. Modifications are requiredto ensure thatat least one ofthe monitors in this MSAis collocated in orderto meetthe QualityAssurance/Controlrequirements. (See 40 CFRPart 58, App. A, 3.2.5, 

# et seq.) In orderto continue ensuring TCEQ's 2011 networkplan will meetthe requirements, werequest thatyou specifywhether you intendto collocate the monitor at this monitoring site or intendto collocate the othermonitoring site located in the same MSA in the March 31, 2011 response.

C. AustinAudubon (Supplemental Speciation, Site LD.48-453-0020): We also disapprove the request for discontinuationofthis monitorbecause, according to the latest available

census figures, itis located in a metropolitan statistical area (MSA) requiredto have a minimum oftwo PM2.5 FRM monitoring sites. This analysis is based onthe 2007-2009 designvalue of22.7 ug/rrr' for this MSA, thepopulation estimates from the 2009 U.S. Census, and 40 CFRPart 58 App. D 4.7.1 Table D-5. Currently, this MSA is servedby thetwo monitors minimally necessaryto meetthe regulatoryrequirements, and EPA may not approve any discontinuationthat leaves this MSAwith only one monitor. (See 40 CFRPart 58, App. D, 4.7.1.) In orderto continue ensuring TCEQ's 2011 networkplan

. will meetthe requirements, we request, by March 31, 2010, thatyou affirm your

continuedreliance onthis monitoring site orprovide us with aplanfor aproposednew site to supportthe discontinuationofthis monitor.

Additionally, we discoveredthatthe PMnetworkfor this MSA does not comply withthe collocationrequirements inAppendixA of40 CFRPart 58. Modifications are requiredto

ensure that at least one ofthe monitors in this MSA is collocated in orderto meetthe QualityAssurance/Control requirements. (See 40 CFRPart 58, App. A, 3.2.5, 

# et seq.) In orderto continue ensuring TCEQ's 2011 networkplanwill meetthe requirements, we request, in the March 31, 2011 response, that you specify whetheryou intendto collocate the monitor at this monitoring site or intendto collocate the othermonitoring site located in the same MSA.

We do notobjectto what we understandto be yourrequest for discontinuation ofthe Corpus Christi Huisache (FRM) (48-355-0032) monitoring site. However, we discovered a discrepancy in the site identificationnumber you listed for this monitor in AppendixA ofyour networkplan. In AppendixA, we believe the site identificationnumberyou listed refers to the Corpus Christi Up RiverRoad Monitoring Station (48-355-0034). Please clarify by March 31, 2011, which station is actuallybeing proposed for decommissioning.

EPA does notobjectto yourrequestto add a collocatedPM2.5 FRM to enhance Quality Assurance/Control at the Corpus Christi Up RiverRoad Monitoring Site (48-355-0034). However, your listin AppendixB ofyournetworkplanindicates thata PM2.5 FRM is currently collocated at the Corpus Christi Huisache site (48-355-0032). Ifthe Corpus Christi Huisache site (48-355-0032) is in fact the site youplanto discontinue, please clarify by March 31, 2011,

2

# whetherthataction would entail decommissioningthe entire PM monitoring station or simply

one ofthe collocatedPM2.5 monitors.
EPA does not object to your requestto add a SPM PM2.5 FRM for selected speciationto supportexceptional events analysis at the Galveston site (48-167-1034). We recommendthat TCEQ evaluatetheir entire PM2.5 networkin its development ofits 2011 Annual Air MonitoringNetworkPlan and consider similar analyses at other key locations such as the ClintonDrive site in Houston. PM2.5 speciation data can provide a more definitivetechnical basis to qualify data caused by an exceptional event.
Appendix B ofyour Annual MonitoringNetworkPlanidentifies two regional transport sites at Big Bend National Park(48-043-0101) and South Padre Island (48-061-2004). In order to continue ensuring TCEQ's 2011 networkplanwill meet the requirements, we request a writtenresponse by March 31, 2011, which either identifies or, ifnecessary, explains your plan to establishat least one PM2.5 regional background site to satisfythe requirements of40 CFR Part 58, App. D, 4.7.3.

TCEQ has proposed no changes to the existing PMIO network. We are pleasedto learn aboutthe addition ofacontinuous PMIO monitor at the ClintonDrive site in Houstonto provide PMIO Air Quality Index informationto the public.



# 2. Lead
We approve the waiverrequests submittedfor the source-orientedlead monitoring requirement at the U.S. Army FortHood facility near Killeenand the Oxbow Calcining facility in PortArthur. EPA is satisfiedwith the informationTCEQ has 

# furnished to demonstrate that these sources will not contributeto amaximum lead (Pb) concentrationin ambient air in excess of50% ofthe NAAQS. EPA approves the Pb monitoring waiverrequest submittedfor the U.S. Army Red River ArmyDepot (RRAD). There are very low RRAD 2009 Pb emissions, which were much lower than 1.0 tons per year (tpy), corresponding withthe relocationofRRAD munitions operations to locations outside ofthe State ofTexas. Approved Pb monitoring waivers are required to be renewed once every five years as part ofthe network assessment required under 40 CFR §58.10(d). Ifthe approvedPb waiver circumstances significantly change, such as a facility Pb emissions increase, the waivers must be resubmitted sooner. (See 40 CFR §58.l0(b)(l0) and 40 CFRPart 58, App. D., 4.5(a)(ii).) EPA's decisionto approve these waivers is based, in part, on the Pb source emissions tpy from the latest 2008 state inventory. It

# is therefore critical that TCEQ maintain its state emissions inventoryto support future evaluation ofthese waivers. (See 40 CFR §51.20 and 40 CFR §51.30.)

The two relocatedExide monitoring sites shouldretain their site Air Quality System (AQS) IDs (48-085-0003 and 48-085-0009). The networkplan currently lists these IDs as "to be determined" in the networklist. Since the relocationdistance ofeach monitor was significantly less than the lowermiddle scale specified in the regulations (100 meters), we request TCEQ confirmin its March 31, 2011 reply thatthe spatial scale will remainidentified as middle scale. (See 40 CFR §58.14(c) and 40 CFR §58.14(c)(6).)



# 3

# In an August 16, 2010 letter from Mark R. 

# Vickery Executive DirectorofTCEQ to the EPA regarding the Exide, Eubanks Streetmonitoring site (48-085-0009), TCEQ expressed a beliefthatthis monitordid not represent ambientair data and recommendedthatreference to this monitorbe removed from EPA's Technical SupportDocument (TSD). We understandthat TCEQ has flagged the pastdata for this monitor as non-regulatory and notNAAQS comparable in AQS. However, this alteration in designationis a drastic change from the 2008 and 2009 Annual MonitoringNetworkPlan submittals where this monitorwas listed as a SLAMS monitor. The data was reported by the State as ambientdata for the last three years. In the current2010 Annual AmbientAirNetworkPlan, this monitorwas still designated as a SLAMS monitor representative ofambient air and NAAQS comparable. EPA notes that the monitorin question was less than five feet from the chain link fence markingthe property line at the monitor location. As such, EPA considers its measurements representative ofambient air across the fence-line. In order to continue ensuring TCEQ's 2011 networkplan will meet the requirements,

we request confirmationthatthe new monitoring site locationfor the Exide Eubanks monitor (48-085-0009) is consideredrepresentative ofambient air by TCEQ in the March 31, 2011, response.
By January 31, 2011, we requestTCEQ confirmthat a source-oriented lead monitoring site is established and operational at the ECS facility in Terrell, Texas, as well as other 1 ton per year sources in order to ensure the 2011 TCEQ networkplanwill meet the requirements. (See 40 CFRPart 58, App. D, 4.5(a) and 40 CFRPart 58, App. D, 4.5(a)(i).)

EPA air monitoring stafflooks forward to working with TCEQ on the implementation of the final Pb monitoring requirements scheduledfor Administrator signing in December, 2010. We expectthe final lead monitoring requirements to be addressed as specifiedin the forthcoming reconsidered lead monitoring regulations. TCEQ is required to adhere to and meet all requirements in the final lead rule. Pleasetake care to acknowledge upcoming regulatory changes in your annual monitoring networkplans and advise EPA ofyour plans to adhere to them. Once the monitoring regulations are finalized, monitoring areas can bere-evaluatedfor any required additional monitoring. We advise all monitoring agencies to refrain from siting and installingPb non-source orientedmonitors until the final Pb reconsiderationmonitoring regulations arepromulgated.



# 3. Relocation ofMonitoring Sites
We approve the terminationofthe monitors at the El Paso Sun Metro site (48-141-0053) in accordance with40 CFRPart 58 App. D, 4.2(a) and 40 CFRPart 58 App. D, 4.7.1 . We have

no objectionto your proposal to establish a new neighborhood site in the El Paso area. The 2010 Annual Air MonitoringNetworkPlan failed to mention a new locationand the conditions ofthe

new monitoring site. Please note that EPA must approve the SLAMS site before it is initiated in accordance with 40 CFRPart 58 App. D, 2(d). We requestTCEQ submitthe new monitoring site locationand conditions for approval intheir 2011 Annual Air MonitoringNetworkPlan.

# 4. Monitoring Sites listed in theNetwork
Currently, the networklistfurnished in Appendix B ofyour submission does notindicate thatNOINOx are monitoredpollutants, onlyN02. We recommendthatyou add a clarifying footnote or addNOINOx in thoserows that currently only list N02. Based on discussions with TCEQ staff, we understandthis to be atypographical omission, andtherefore request TCEQ confirmthatthese changes have beenmade by submitting a revised Appendix B by January 31, 2011.

All meteorological parameters for PhotochemicalAssessmentMonitoring Station and National Core sites are currently missing and needto be included in Appendix B ofyour network plan. (See 40 CFR §58.1O(b)(3), 40 CFRPart 58, App. D, 3(b), 40 CFRPart 58 App. D,S, and 40 CFRPart 58 App. D, 5.1.) Based on discussions withTCEQ staff, we understandthis to be a typographical omission, and therefore request TCEQ confirmthatthese changes have beenmade by submitting arevisedAppendix B by January 31, 2011.

The required speciated volatile organic carbons and total non-methane organic carbons at the Channelview site (48-201-0026), required carbonyl sampling at the Clinton Drive site (48- 201-1035), andthe required

# Radar Profiler at the Waterworks site (48-201-0241) are currently missing from AppendixB butrequire inclusion. Based on discussions with TCEQ staff, we understandthis to be atypographical omission, and therefore requestTCEQ confirmthatthese changes havebeenmade by submitting arevisedAppendixB by January 31, 2011. (See 40 CFR Part 58, App. D, 5.3,40 CFR §58.10(b)(3), and 40 CFRPart 58 App. D,S.! etseq.)

Three critical ozone monitoring sites were notincluded in Appendix B ofthe network plan: Wallisville (48-201-0617) in Houston, and Jefferson CountyAirport (48-245-0018) and Sabine Pass (48-245-0101) in Beaumont-PortArthur. In a May 28, 2010 letterfrom Mr. Thomas Diggs ofmy staffto Mr. MatthewBaker and Mr. David Brymerofyour staff, EPArequested thatthese three sites be listedin the Annual Air Monitoring NetworkPlan. In yourJuly 26,2010 response letterfrom Mr. David Bower and Mr. DavidBrymerofyour staff, TCEQ statedits intentionto add the Jefferson CountyAirport and Sabine Pass sites to the Annual Air Monitoring NetworkPlanin the future. Therefore, we lookforward to these two sites being listed in the upcoming 2011 Annual AirMonitoringNetworkPlan. We also reaffirm ourrequestthatthe Wallisville site be listed in the TCEQ Annual Air Monitoring NetworkPlan. EPA currently views thesethree ozone sites as necessary for the adequacy ofthe TCEQ ozone monitoring network, based on 40 CFRPart 58, Appendix D, Section 1. Accordingly, EPA requests thatthe Jefferson County Airport, Sabine Pass, andWallisville ozonemonitors be addedto the upcoming 2011 Annual Air Monitoring NetworkPlan as ozone special purposemonitors (SPMs). We recommendthe SPMs site classificationbecause TCEQ is currentlyrelying upon athird party contractorfor operation ofthe ozone monitors atthose sites. Ifthe contractordecides to terminate ozone monitoring atthose three sites in the future, TCEQ will needto install their own
ozone monitors at those three sites and reclassifythe sites as SLAMS in orderto continue meeting network adequacy requirements. (See 40 CFRPart 58, App. D., 4.1(a) and 

# (f), and 40 CFRPart 58, App. D, 1.1.1 etseq.) In orderto continue workingtowards a resolutionbefore the submittal ofthe 2011 annual networkplan, we request, by January 31, 2011, TCEQ confirmtheir intentionto list the Jefferson County Airport, Sabine Pass, andWallisville ozone sites as SPMs

5

# in the upcoming 2011 Annual Air MonitoringNetworkPlan, or establishtheir own SLAMS monitors at these locations in orderto ensure an adequate air monitoring network. IfTCEQ decides to establishtheir own monitors at these locations, please note thatEPA must approve each SLAMS site before it is initiatedin accordancewith40 CFRPart 58 App. D, 2(d).

In your August 16, 2010 letter to EPA and after further discussions withTCEQ staff, questions were raisedregardingthe ambient air designationand site accessibility to the general public formultiple TCEQ airmonitoring sites. After ajointreview ofall the monitoring sites includedin the TCEQ networkduring a Technical Systems Audit, 31 ofthe sites listed in Appendix B ofTCEQ's networkplan drew concern. The questionable sites are listed in AppendixA ofthis enclosure. EPA considers all ofthe TCEQ sites listed in Appendix B ofthe networkplanto measure ambientair quality. We requestTCEQ confirmthatall monitoring sites are ambient air monitoring sites by December 30, 2010, as previously stated by TCEQ staff during the Technical Systems Auditin September2010.

5. Data Submittal and Certification

The EPA is still awaiting TCEQ submittalofthe certification for lead and air toxies 2009 data. All 2009 data should have been submitted and certifiedby May 1,2010, according to 40 CFRPart §58.l5(a)(2). Portions ofthe data from the first two quarters of2010 has also not been submittedinto AQS as specified by 40 CFR §58.16(a)-(c). As soon as possible, please submitall required data and certifications into the AQS systemfor allmonitoring sites required in the TCEQ network. In 

# order to continueto ensure the 2011 networkplanmeets the requirements, please submitan update on whenthe missing data and certifications were submittedin your March 31, 2011 response letter.

The measurement scale for all monitors needs to be includedfor all applicable parameter codes, i.e., parametercode 14129. In order to continueto ensure the 2011 networkplanmeets the requirements, we requestTCEQ confirm thatthe measurement scales for all monitors are includedfor all applicableparametercodes by March 31, 20II.
