Post Office Box 13087

Austin, Texas 78711-3087

Dear Mr. Vickery:

Over the past year, the U.S. Environmental Protection Agency (EPA) Region 6 and the

Texas Commission on Environmental Quality (TCEQ) have been in discussions concerning the

requirements ofTCEQ's Annual Monitoring Network Plan. These efforts have led to a better

understanding ofthe issues facing the TCEQ air monitoring network, and while progress has

been made, several network design issues still require attention.

On June 30, 2010, TCEQ submitted its 2010 Annual Air Monitoring Network Plan for

our review and consideration for approval. EPA has completed its analysis ofthe TCEQ 2010

Annual Monitoring Network Plan to ensure it meets those requirements of 40 CFR Part 58 and

its appendices that confer approval authority on the Regional Administrator. EPA generally

approves your network plan, in accordance with 40 CFR §58.10 and §58.14. However, this

approval is based on the expectation that TCEQ will resolve the issues identified in the enclosure

before the submittal ofthe 2011 network plan. The ability ofEPA to approve TCEQ's 2011

network plan depends on the resolution ofthese issues, which include network changes needed

to meet the regulatory requirements for PM2.s, lead and ozone air monitoring for National

Ambient Air Quality Standards (NAAQS); system requirements for the National Core (NCore)

Network; TCEQ certification of all 2009 data and submittal of data for the first two quarters of

2010; and confirmation on TCEQ's position regarding the 31 air monitoring sites discussed

during the Technical Systems Audit.

The network assessment process presents an opportunity for EPA and TCEQ to

collaborate on network design issues in accordance with 40 CFR Part 58 App. D, 1.1.2.

During discussions with your staff, EPA outlined the schedule of deadlines identified in the

enclosure. These deadlines were established in order to ensure timely resolution ofthe enclosed

issues before the submittal ofthe 2011 Annual Network Plan. Please submit a response by

March 31, 20II,· explaining how TCEQ has addressed each issue.

Additionally, in accordance with 40 CFR Part 58 App. D, 4.5(a)(ii), EPA approves your

source-oriented lead monitoring requirement waiver requests for the Red River Army Depot

(near Texarkana), the Ft. Hood facility (near Killeen), and Oxbow Calcining (in Port Arthur).

Approved lead monitoring waivers are required to be renewed once every five years as part of

the network assessment required under 40 CFR §58.1O(d).

Annual Monitoring Network Plan Issues

October 28, 2010

1. Particulate Matter

During our review, we discovered that the 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, if collocated continuous samplers are not present, must run on at least a l-in-3 day

schedule. (See 40 CFR §58.l2(d).) These monitors apparently do not conform to the monitoring

schedule requirements of 40 CFR §58.l2. We note that Region 6, U.S. Environmental

Protection Agency (EPA) has not received nor approved any operational exemption requests for

sampling frequency for these monitoring sites. Accordingly, we request the l-in-3 day schedule

be applied to these monitors, and Texas Commission ofEnvironmental Quality (TCEQ) must

state that it is meeting this schedule in the written response due March 31, 2011.

We have evaluated your requests for discontinuation ofthirteen PM2.5 monitors from

your operating network in accordance with the criteria at 40 CFR §58.14(c). Based on current

design values, we do not object to your proposals to discontinue 10 ofthe 13 SLAMS monitors

identified in Appendix A of your 2010 Annual Monitoring Network Plan. However, for the

reasons discussed below, EPA cannot approve your requests as proposed with respect to the

following three SLAMS monitors:

A. Fort Worth Northwest (FRM) (48-439-1002): The requested discontinuation ofthis

monitor would leave the Fort Worth-Arlington Metropolitan Division, an area consisting

of approximately two million people, with only one remaining monitor. Ifthe site were

decommissioned as proposed, it would leave only the Congress Street site (48-439-1006)

monitor to compare with the National Ambient Air Quality Standards (NAAQS) for

PM2.5. One monitor does not provide sufficient monitoring coverage for such a highly

populated area. (See 40 CFR Part 58, App. D, 4.7.1.) In order to continue ensuring

TCEQ's 2011 network plan will meet the requirements, we request that you affirm your

continued reliance on this monitor or provide us with a plan for a proposed new site to

support the 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 with only one remaining monitor. According to the

latest available census figures, the monitor is located in a metropolitan statistical area

(MSA) required to have a minimum oftwo PM2.5 FRM monitoring sites. This analysis

is based on the 2008-2009 design value estimate of 22.4 ug/rrr' for this MSA, the

population estimates from the 2009 U.S. Census, and 40 CFR Part 58 App. D 4.7.1 Table

D-5. We understand this MSA currently has the minimum number ofmonitors necessary

to meet regulatory requirements, i.e., two monitors, and the discontinuation ofthe

requested monitor would 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 network plan will meet the .

requirements, we request that you affirm your continued reliance on this monitor or

1
provide us with a plan for a proposed new site to support the discontinuation ofthis

monitor by March 31, 2011.

Additionally, we discovered that the PM2.5 network for this MSA does not comply with

the collocation requirements in Appendix A of 40 CFR Part 58. Modifications are

required to ensure that at least one ofthe monitors in this MSA is collocated in order to

meet the Quality Assurance/Control requirements. (See 40 CFR Part 58, App. A, 3.2.5,

et seq.) In order to continue ensuring TCEQ's 2011 network plan will meet the

requirements, we request that you specify whether you intend to collocate the monitor at

this monitoring site or intend to collocate the other monitoring site located in the same

MSA in the March 31, 2011 response.

C. Austin Audubon (Supplemental Speciation, Site LD.48-453-0020): We also disapprove

the request for discontinuation ofthis monitor because, according to the latest available

census figures, it is located in a metropolitan statistical area (MSA) required to have a

minimum oftwo PM2.5 FRM monitoring sites. This analysis is based on the 2007-2009

design value of22.7 ug/rrr' for this MSA, the population estimates from the 2009 U.S.

Census, and 40 CFR Part 58 App. D 4.7.1 Table D-5. Currently, this MSA is served by

the two monitors minimally necessary to meet the regulatory requirements, and EPA may

not approve any discontinuation that leaves this MSA with only one monitor. (See 40

CFR Part 58, App. D, 4.7.1.) In order to continue ensuring TCEQ's 2011 network plan

. will meet the requirements, we request, by March 31, 2010, that you affirm your

continued reliance on this monitoring site or provide us with a plan for a proposed new

site to support the discontinuation ofthis monitor.

Additionally, we discovered that the PM network for this MSA does not comply with the

collocation requirements in Appendix A of 40 CFR Part 58. Modifications are required to

ensure that at least one ofthe monitors in this MSA is collocated in order to meet the

Quality Assurance/Control requirements. (See 40 CFR Part 58, App. A, 3.2.5, et seq.) In

order to continue ensuring TCEQ's 2011 network plan will meet the requirements, we

request, in the March 31, 2011 response, that you specify whether you intend to collocate

the monitor at this monitoring site or intend to collocate the other monitoring site located

in the same MSA.

We do not object to what we understand to be your request for discontinuation ofthe

Corpus Christi Huisache (FRM) (48-355-0032) monitoring site. However, we discovered a

discrepancy in the site identification number you listed for this monitor in Appendix A of your

network plan. In Appendix A, we believe the site identification number you listed refers to the

Corpus Christi Up River Road Monitoring Station (48-355-0034). Please clarify by March 31,

2011, which station is actually being proposed for decommissioning.

EPA does not object to your request to add a collocated PM2.5 FRM to enhance Quality

Assurance/Control at the Corpus Christi Up River Road Monitoring Site (48-355-0034).

However, your list in Appendix B of your network plan indicates that a 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 you plan to discontinue, please clarify by March 31, 2011,

2
whether that action would entail decommissioning the entire PM monitoring station or simply

one ofthe collocated PM2.5 monitors.

EPA does not object to your request to add a SPM PM2.5 FRM for selected speciation to

support exceptional events analysis at the Galveston site (48-167-1034). We recommend that

TCEQ evaluate their entire PM2.5 network in its development ofits 2011 Annual Air

Monitoring Network Plan and consider similar analyses at other key locations such as the

Clinton Drive site in Houston. PM2.5 speciation data can provide a more definitive technical

basis to qualify data caused by an exceptional event.

Appendix B of your Annual Monitoring Network Plan identifies 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 network plan will meet the requirements, we request a

written response by March 31, 2011, which either identifies or, if necessary, explains your plan

to establish at least one PM2.5 regional background site to satisfy the requirements of 40 CFR

Part 58, App. D, 4.7.3.

TCEQ has proposed no changes to the existing PMIO network. We are pleased to learn

about the addition of a continuous PMIO monitor at the Clinton Drive site in Houston to provide

PMIO Air Quality Index information to the public.

2. Lead

We approve the waiver requests submitted for the source-oriented lead monitoring

requirement at the U.S. Army Fort Hood facility near Killeen and the Oxbow Calcining facility

in Port Arthur. EPA is satisfied with the information TCEQ has furnished to demonstrate that

these sources will not contribute to a maximum lead (Pb) concentration in ambient air in excess

of 50% ofthe NAAQS. EPA approves the Pb monitoring waiver request submitted for the U.S.

Army Red River Army Depot (RRAD). There are very low RRAD 2009 Pb emissions, which

were much lower than 1.0 tons per year (tpy), corresponding with the relocation ofRRAD

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 approved Pb 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 CFR Part 58, App. D., 4.5(a)(ii).) EPA's decision to 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 inventory to support

future evaluation ofthese waivers. (See 40 CFR §51.20 and 40 CFR §51.30.)

The two relocated Exide monitoring sites should retain their site Air Quality System

(AQS) IDs (48-085-0003 and 48-085-0009). The network plan currently lists these IDs as "to be

determined" in the network list. Since the relocation distance of each monitor was significantly

less than the lower middle scale specified in the regulations (100 meters), we request TCEQ

confirm in its March 31, 2011 reply that the spatial scale will remain identified 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 Director of TCEQ to the

EPA regarding the Exide, Eubanks Street monitoring site (48-085-0009), TCEQ expressed a

beliefthat this monitor did not represent ambient air data and recommended that reference to this

monitor be removed from EPA's Technical Support Document (TSD). We understand that

TCEQ has flagged the past data for this monitor as non-regulatory and not NAAQS comparable

in AQS. However, this alteration in designation is a drastic change from the 2008 and 2009

Annual Monitoring Network Plan submittals where this monitor was listed as a SLAMS monitor.

The data was reported by the State as ambient data for the last three years. In the current 2010

Annual Ambient Air Network Plan, this monitor was still designated as a SLAMS monitor

representative of ambient air and NAAQS comparable. EPA notes that the monitor in question

was less than five feet from the chain link fence marking the property line at the monitor

location. As such, EPA considers its measurements representative of ambient air across the

fence-line. In order to continue ensuring TCEQ's 2011 network plan will meet the requirements,

we request confirmation that the new monitoring site location for the Exide Eubanks monitor

(48-085-0009) is considered representative of ambient air by TCEQ in the March 31, 2011,

response.

By January 31, 2011, we request TCEQ confirm that 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 network plan will meet the requirements. (See

40 CFR Part 58, App. D, 4.5(a) and 40 CFR Part 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 scheduled for Administrator signing in December, 2010.

We expect the final lead monitoring requirements to be addressed as specified in the forthcoming

reconsidered lead monitoring regulations. TCEQ is required to adhere to and meet all

requirements in the final lead rule. Please take care to acknowledge upcoming regulatory

changes in your annual monitoring network plans and advise EPA of your plans to adhere to

them. Once the monitoring regulations are finalized, monitoring areas can be re-evaluated for

any required additional monitoring. We advise all monitoring agencies to refrain from siting and

installing Pb non-source oriented monitors until the final Pb reconsideration monitoring

regulations are promulgated.

3. Relocation ofMonitoring Sites

We approve the termination ofthe monitors at the El Paso Sun Metro site (48-141-0053)

in accordance with 40 CFR Part 58 App. D, 4.2(a) and 40 CFR Part 58 App. D, 4.7.1 . We have

no objection to your proposal to establish a new neighborhood site in the El Paso area. The 2010

Annual Air Monitoring Network Plan failed to mention a new location and the conditions ofthe

new monitoring site. Please note that EPA must approve the SLAMS site before it is initiated in

accordance with 40 CFR Part 58 App. D, 2(d). We request TCEQ submit the new monitoring

site location and conditions for approval in their 2011 Annual Air Monitoring Network Plan.

4
4. Monitoring Sites listed in the Network

Currently, the network list furnished in Appendix B of your submission does not indicate

that NOINOx are monitored pollutants, only N02. We recommend that you add a clarifying

footnote or add NOINOx in those rows that currently only list N02. Based on discussions with

TCEQ staff, we understand this to be a typographical omission, and therefore request TCEQ

confirm that these changes have been made by submitting a revised Appendix B by January 31,

2011.

All meteorological parameters for Photochemical Assessment Monitoring Station and

National Core sites are currently missing and need to be included in Appendix B of your network

plan. (See 40 CFR §58.1O(b)(3), 40 CFR Part 58, App. D, 3(b), 40 CFR Part 58 App. D,S, and

40 CFR Part 58 App. D, 5.1.) Based on discussions with TCEQ staff, we understand this to be a

typographical omission, and therefore request TCEQ confirm that these changes have been made

by submitting a revised Appendix 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), and the required Radar Profiler at the Waterworks site (48-201-0241) are currently

missing from Appendix B but require inclusion. Based on discussions with TCEQ staff, we

understand this to be a typographical omission, and therefore request TCEQ confirm that these

changes have been made by submitting a revised Appendix B by January 31, 2011. (See 40 CFR

Part 58, App. D, 5.3,40 CFR §58.10(b)(3), and 40 CFR Part 58 App. D,S.! et seq.)

Three critical ozone monitoring sites were not included in Appendix B ofthe network

plan: Wallisville (48-201-0617) in Houston, and Jefferson County Airport (48-245-0018) and

Sabine Pass (48-245-0101) in Beaumont-Port Arthur. In a May 28, 2010 letter from Mr. Thomas

Diggs ofmy staffto Mr. Matthew Baker and Mr. David Brymer of your staff, EPA requested

that these three sites be listed in the Annual Air Monitoring Network Plan. In your July 26,2010

response letter from Mr. David Bower and Mr. David Brymer of your staff, TCEQ stated its

intention to add the Jefferson County Airport and Sabine Pass sites to the Annual Air Monitoring

Network Plan in the future. Therefore, we look forward to these two sites being listed in the

upcoming 2011 Annual Air Monitoring Network Plan. We also reaffirm our request that the

Wallisville site be listed in the TCEQ Annual Air Monitoring Network Plan. EPA currently

views these three ozone sites as necessary for the adequacy ofthe TCEQ ozone monitoring

network, based on 40 CFR Part 58, Appendix D, Section 1. Accordingly, EPA requests that the

Jefferson County Airport, Sabine Pass, and Wallisville ozone monitors be added to the upcoming

2011 Annual Air Monitoring Network Plan as ozone special purpose monitors (SPMs). We

recommend the SPMs site classification because TCEQ is currently relying upon a third party

contractor for operation ofthe ozone monitors at those sites. Ifthe contractor decides to

terminate ozone monitoring at those three sites in the future, TCEQ will need to install their own

ozone monitors at those three sites and reclassify the sites as SLAMS in order to continue

meeting network adequacy requirements. (See 40 CFR Part 58, App. D., 4.1(a) and (f), and 40

CFR Part 58, App. D, 1.1.1 et seq.) In order to continue working towards a resolution before the

submittal ofthe 2011 annual network plan, we request, by January 31, 2011, TCEQ confirm their

intention to list the Jefferson County Airport, Sabine Pass, and Wallisville ozone sites as SPMs

5
in the upcoming 2011 Annual Air Monitoring Network Plan, or establish their own SLAMS

monitors at these locations in order to ensure an adequate air monitoring network. IfTCEQ

decides to establish their own monitors at these locations, please note that EPA must approve

each SLAMS site before it is initiated in accordance with 40 CFR Part 58 App. D, 2(d).

In your August 16, 2010 letter to EPA and after further discussions with TCEQ staff,

questions were raised regarding the ambient air designation and site accessibility to the general

public for multiple TCEQ air monitoring sites. After a joint review of all the monitoring sites

included in the TCEQ network during a Technical Systems Audit, 31 ofthe sites listed in

Appendix B ofTCEQ's network plan drew concern. The questionable sites are listed in

Appendix A ofthis enclosure. EPA considers all ofthe TCEQ sites listed in Appendix B ofthe

network plan to measure ambient air quality. We request TCEQ confirm that all monitoring sites

are ambient air monitoring sites by December 30, 2010, as previously stated by TCEQ staff

during the Technical Systems Audit in September 2010.

5. Data Submittal and Certification

The EPA is still awaiting TCEQ submittal ofthe certification for lead and air toxies 2009

data. All 2009 data should have been submitted and certified by May 1,2010, according to 40

CFR Part §58.l5(a)(2). Portions ofthe data from the first two quarters of2010 has also not been

submitted into AQS as specified by 40 CFR §58.16(a)-(c). As soon as possible, please submit all

required data and certifications into the AQS system for all monitoring sites required in the

TCEQ network. In order to continue to ensure the 2011 network plan meets the requirements,

please submit an update on when the missing data and certifications were submitted in your

March 31, 2011 response letter.

The measurement scale for all monitors needs to be included for all applicable parameter

codes, i.e., parameter code 14129. In order to continue to ensure the 2011 network plan meets

the requirements, we request TCEQ confirm that the measurement scales for all monitors are

included for all applicable parameter codes by March 31, 20II.
