Docket No.: 2015-1651-SIP
Subject:

Commission Approval for Proposed Collin County Redesignation Request
and Maintenance Plan State Implementation Plan (SIP) Revision for the
2008 Lead National Ambient Air Quality Standard (NAAQS)
Collin County Lead Redesignation and Maintenance Plan SIP Revision
Non-Rule Project No. 2016-003-SIP-NR

Background and reason(s) for the SIP revision:
On October 15, 2008, the United States Environmental Protection Agency (EPA)
substantially revised the lead NAAQS from 1.5 micrograms per cubic meter (µg/m3),
established in 1978, to a new level of 0.15 µg/m3. Effective December 31, 2010, the EPA
designated an area surrounding Exide Technologies (Exide) located in Frisco, Collin
County, as nonattainment for the 2008 lead NAAQS (75 FR 71033).
Section 110(a)(1) of the Federal Clean Air Act (FCAA) requires states to submit a SIP
revision for areas that have been designated nonattainment to provide for the
implementation, maintenance, and enforcement of the NAAQS. On August 8, 2012, the
commission approved adoption of the Collin County Attainment Demonstration SIP
Revision for the 2008 Lead NAAQS and an Agreed Order between the Texas Commission
on Environmental Quality (commission) and Exide. The control measures and contingency
measures that were identified for the Collin County Lead Attainment Demonstration SIP
revision were made enforceable through Agreed Order No. 2011-0521-MIS between the
commission and Exide. The Agreed Order provided that enforceable measures be
implemented to reduce lead emissions in the Collin County lead nonattainment area as
soon as possible but no later than January 6, 2014. The SIP revision and Agreed Order
contained contingency measures designed to ensure continued compliance with the
standard.
On June 4, 2012, the City of Frisco and Exide approved an agreement involving the sale of
approximately 180 acres of undeveloped land surrounding Exide's plant. Under the terms
of the agreement, the land around Exide’s plant would be purchased by the Frisco
Community Development Corporation and the Frisco Economic Development
Corporation. The agreement stipulates that Exide will retain ownership of and
responsibility for cleaning up the permitted plant site. The SIP revision and Agreed Order
were revised on August 8, 2012 to reflect this agreement, approved by the commission on
August 8, 2012, and submitted to the EPA on October 10, 2012.

Re: Docket No. 2015-1651-SIP
Instead of implementing control measures identified in the SIP revision and Agreed Order
for continued operation, per Exide’s agreement with the City of Frisco, Exide chose the
option to close the plant and cease all production activities. Exide began curtailing certain
recycling operations on November 1, 2012 and ceased all recycling operations on
November 30, 2012. The facility is now permanently shut down. Decontamination and
demolition of Exide’s lead recycling facility was completed on August 15, 2013. Soil
remediation activities at the plant site and surrounding property are still being conducted.
The area is required to have the three-month rolling average monitoring data below the
NAAQS for 36 consecutive months to comply with the NAAQS. Between January 1, 2013
and December 31, 2015, all three-month rolling averages were below the lead NAAQS. The
current design value is 0.08 µg/m3 as of December 31, 2015. Thus, the area achieved
compliance with the 2008 lead NAAQS by December 31, 2015.
Certification of 2015 lead data for the Frisco area was submitted to the EPA on February
29, 2016 (attached), in advance of the May 1, 2016 certification deadline. Validated 2015
data is necessary to demonstrate the area has monitored attainment of the lead NAAQS.
Scope of the SIP revision:
A.) Summary of what the SIP revision will do:
This proposed SIP revision would request that the Collin County nonattainment area be
redesignated to attainment for the 2008 lead standard and provide a maintenance plan
that would ensure the area remains in attainment of the standard through 2028.
B.) Scope required by federal regulations or state statutes:
Section 107(d)(3)(E) of the FCAA states that the EPA can redesignate an area to attainment
if the following conditions are met.
• The EPA has determined that the NAAQS has been attained.
• The applicable implementation plan has been fully approved by the EPA under
Section 110(k).
• The EPA has determined that the improvement in air quality is due to permanent
and enforceable reductions in emissions.
• The EPA has fully approved a maintenance plan, including a contingency plan, for
the area under Section 175A.
• The state has met all applicable requirements for the area under the FCAA, Section
110 and Part D.
Section 175A(a) of the FCAA indicates that states that submit a request for redesignation for
attaining the NAAQS shall also submit a maintenance plan to provide for the maintenance
of the standard for at least 10 years from the effective date of approval of the maintenance
plan by the EPA.
C.) Additional staff recommendations that are not required by federal rule or
state statute:

Commissioners
Page 3
April 8, 2016
Re: Docket No. 2015-1651-SIP
None.
Statutory authority:
The authority to propose and adopt the SIP revision is derived from FCAA, §110, which
requires states to submit SIP revisions that contain enforceable measures to achieve the
NAAQS, FCAA, §175A, regarding maintenance plans, and other general and specific
authority in Texas Water Code, Chapters 5 and 7, and Texas Health and Safety Code,
Chapter 382.
Effect on the:
A.) Regulated community:
There would be no impact since Exide ceased operations and permanently shut down the
plant.
B.) Public:
If approved by the EPA, the public would benefit from continued maintenance of air
quality and not having an area designated as nonattainment for the lead NAAQS in the
local area.
C.) Agency programs:
The agency will continue to use existing resources to monitor ambient air quality. The Air
Quality Division will continue to coordinate with the Remediation Division during the
remediation process.
Stakeholder meetings:
Solicitation of public comment and public hearing will occur after commission approval of
the proposal. Because there are no new rules associated with this SIP revision, no
stakeholder meetings are planned.
Potential controversial concerns and legislative interest:
During the development of the Collin County Attainment Demonstration for the 2008
Lead NAAQS SIP revision (Project No. 2011-001-SIP-NR), the EPA expressed concern
regarding the impact of remediation of the Exide facility on ambient lead concentrations
near the site. As the remediation of the site has been delayed and is anticipated to be
ongoing throughout the maintenance period, the EPA may request special consideration of
this issue in the maintenance plan.
Will this SIP revision affect any current policies or require development of
new policies?
No

Re: Docket No. 2015-1651-SIP
What are the consequences if this SIP revision does not go forward? Are there
alternatives to a SIP revision?
The commission could choose to not submit a request for redesignation and the area would
remain as nonattainment.

EXECUTIVE SUMMARY
On October 15, 2008, the United States Environmental Protection Agency (EPA) substantially
revised the lead National Ambient Air Quality Standard (NAAQS) from 1.5 micrograms per
cubic meter (µg/m3), established in 1978, to a level of 0.15 µg/m3. Effective December 31, 2010,
the EPA designated an area surrounding Exide Technologies (Exide) located in Frisco, Collin
County, as nonattainment for the 2008 lead NAAQS (75 Federal Register 71033). Under the
nonattainment designation, the area was given until December 31, 2015, to attain the lead
standard. To demonstrate attainment, the area is required to have three-month rolling average
monitoring data below the NAAQS for 36 consecutive months. Between January 1, 2013 and
December 31, 2015, there was not a three-month rolling average above the lead NAAQS. The
current design value is 0.08 µg/m3 as of December 31, 2015. Thus, the area achieved compliance
of the 2008 lead NAAQS by the December 31, 2015 deadline.
Section 107(d)(3)(E) of the Federal Clean Air Act (FCAA) states that the EPA can redesignate an
area to attainment if all of the following conditions are met.
1. The EPA has determined that the NAAQS have been attained.
2. The applicable implementation plan has been fully approved by the EPA under the FCAA,
Section 110(k).
3. The EPA has determined that the improvement in air quality is due to permanent and
enforceable reductions in emissions.
4. The EPA has fully approved a maintenance plan, including a contingency plan, for the area
under Section 175A of the FCAA.
5. The state has met all applicable requirements for the area under the FCAA, Section 110 and
Part D.
The EPA’s redesignation guidance recommends that states seeking redesignation of a
nonattainment area consider the following provisions in their maintenance plan: 1




an attainment emissions inventory;
a maintenance demonstration;
verification of continued attainment;
monitoring network verification; and
a contingency plan.

With this proposed state implementation plan revision, the Texas Commission on
Environmental Quality is submitting a request that the Collin County lead nonattainment area
be redesignated to attainment for the 2008 lead standard and that the EPA approve the
associated proposed maintenance plan.

SECTION V-A: LEGAL AUTHORITY
General
The Texas Commission on Environmental Quality (TCEQ) has the legal authority to implement,
maintain, and enforce the National Ambient Air Quality Standards (NAAQS) and to control the
quality of the state’s air, including maintaining adequate visibility.
The first air pollution control act, known as the Clean Air Act of Texas, was passed by the Texas
Legislature in 1965. In 1967, the Clean Air Act of Texas was superseded by a more
comprehensive statute, the Texas Clean Air Act (TCAA), found in Article 4477-5, Vernon’s Texas
Civil Statutes. The legislature amended the TCAA in 1969, 1971, 1973, 1979, 1985, 1987, 1989,
1991, 1993, 1995, 1997, 1999, 2001, 2003, 2005, 2007, 2009, 2011, 2013, and 2015. In 1989, the
TCAA was codified as Chapter 382 of the Texas Health and Safety Code.
Originally, the TCAA stated that the Texas Air Control Board (TACB) is the state air pollution
control agency and is the principal authority in the state on matters relating to the quality of air
resources. In 1991, the legislature abolished the TACB effective September 1, 1993, and its
powers, duties, responsibilities, and functions were transferred to the Texas Natural Resource
Conservation Commission (TNRCC). With the creation of the TNRCC, the authority over air
quality is found in both the Texas Water Code and the TCAA. Specifically, the authority of the
TNRCC is found in Chapters 5 and 7 of the Water Code. Chapter 5, Subchapters A - F, H - J, and
L, include the general provisions, organization, and general powers and duties of the TNRCC,
and the responsibilities and authority of the executive director. Chapter 5 also authorizes the
TNRCC to implement action when emergency conditions arise and to conduct hearings. Chapter
7 gives the TNRCC enforcement authority. In 2001, the 77th Texas Legislature continued the
existence of the TNRCC until September 1, 2013, and changed the name of the TNRCC to the
TCEQ. In 2009, the 81st Texas Legislature, during a special session, amended section 5.014 of
the Texas Water Code, changing the expiration date of the TCEQ to September 1, 2011, unless
continued in existence by the Texas Sunset Act. In 2011, the 82nd Texas Legislature continued
the existence of the TCEQ until 2023.
The TCAA specifically authorizes the TCEQ to establish the level of quality to be maintained in
the state’s air and to control the quality of the state’s air by preparing and developing a general,
comprehensive plan. The TCAA, Subchapters A - D, also authorize the TCEQ to collect
information to enable the commission to develop an inventory of emissions; to conduct research
and investigations; to enter property and examine records; to prescribe monitoring
requirements; to institute enforcement proceedings; to enter into contracts and execute
instruments; to formulate rules; to issue orders taking into consideration factors bearing upon
health, welfare, social and economic factors, and practicability and reasonableness; to conduct
hearings; to establish air quality control regions; to encourage cooperation with citizens’ groups
and other agencies and political subdivisions of the state as well as with industries and the
federal government; and to establish and operate a system of permits for construction or
modification of facilities.
Local government authority is found in Subchapter E of the TCAA. Local governments have the
same power as the TCEQ to enter property and make inspections. They also may make
recommendations to the commission concerning any action of the TCEQ that affects their
territorial jurisdiction, may bring enforcement actions, and may execute cooperative agreements
with the TCEQ or other local governments. In addition, a city or town may enact and enforce
ordinances for the control and abatement of air pollution not inconsistent with the provisions of
the TCAA and the rules or orders of the commission.
i

Subchapters G and H of the TCAA authorize the TCEQ to establish vehicle inspection and
maintenance programs in certain areas of the state, consistent with the requirements of the
Federal Clean Air Act; coordinate with federal, state, and local transportation planning agencies
to develop and implement transportation programs and measures necessary to attain and
maintain the NAAQS; establish gasoline volatility and low emission diesel standards; and fund
and authorize participating counties to implement vehicle repair assistance, retrofit, and
accelerated vehicle retirement programs.

CHAPTER 1: GENERAL
1.1 BACKGROUND
“The History of the Texas State Implementation Plan (SIP),” a comprehensive overview of the
SIP revisions submitted to the United States Environmental Protection Agency (EPA) by the
State of Texas, is available on the Introduction to the SIP Web page
(http://www.tceq.texas.gov/airquality/sip/sipintro.html#History) on the Texas Commission on
Environmental Quality's (TCEQ) website (http://www.tceq.texas.gov).
1.2 PURPOSE
The Texas Commission on Environmental Quality (TCEQ) is seeking redesignation of the Collin
County lead nonattainment area to attainment for the 2008 lead National Ambient Air Quality
Standard (NAAQS) under section 107(d)(3)(E) of the Federal Clean Air Act (FCAA), which states
that the United States Environmental Protection Agency (EPA) can redesignate an area to
attainment if all of the following conditions are met.
1. The EPA has determined that the NAAQS have been attained.
2. The applicable implementation plan has been fully approved by the EPA under the FCAA,
Section 110(k).
3. The EPA has determined that the improvement in air quality is due to permanent and
enforceable reductions in emissions.
4. The EPA has fully approved a maintenance plan, including a contingency plan, for the area
under Section 175A of the FCAA.
5. The state has met all applicable requirements for the area under the FCAA, Section 110 and
Part D.
The purpose of this proposed state implementation plan (SIP) revision is to address all of the
above requirements, including submittal of a maintenance plan that will fulfill the requirements
under Section 107(d)(3)(E) of the FCAA and ensure the Collin County lead nonattainment area
continues to attain the 2008 lead standard. This proposed revision includes a commitment to
submit a second 10-year maintenance plan in eight years as required by the FCAA, i.e., two years
before the end of the first 10-year maintenance plan period.
1.3 LEAD HISTORY IN THE COLLIN COUNTY AREA
The EPA designated a portion of Collin County as a lead nonattainment area for the 1978 lead
NAAQS on November 6, 1991 (56 Federal Register (FR) 56694). The EPA approved the Collin
County lead attainment demonstration SIP revision for the 1978 lead NAAQS on November 29,
1994 (59 FR 60930). The EPA redesignated the area to attainment and approved a 10-year
maintenance plan in October 15, 1999 (64 FR 55421). In 2009, the TCEQ submitted to the EPA a
second and final 10-year maintenance plan for the 1978 lead NAAQS. The maintenance plan
included contingency measures to promptly correct any violation of the 1978 lead NAAQS.
On November 12, 2008, the EPA substantially revised the NAAQS for lead. The standard, set at
0.15 micrograms per cubic meter (µg/m3), measured as a rolling three-month average, is
significantly more stringent than the 1978 standard of 1.5 µg/m3, measured as a quarterly
average (73 FR 66964). On November 22, 2010, the EPA designated a portion of Collin County
surrounding Exide Technologies (Exide) as nonattainment for the 2008 lead NAAQS, effective
December 31, 2010 (75 FR 71033). Figure 1-1: Map of Collin County Lead Nonattainment Area
for the 2008 Lead NAAQS provides a visual representation of the nonattainment area.

Figure 1-1: Map of Collin County Lead Nonattainment Area for the 2008 Lead
NAAQS
On August 8, 2012, the commission approved adoption of the Collin County Attainment
Demonstration SIP Revision for the 2008 Lead NAAQS and an Agreed Order between the TCEQ
and Exide. In accordance with FCAA, §172 and implementation guidance published with the
November 12, 2008, final lead NAAQS (73 FR 66964), the SIP revision contained a reasonably
1-2

available control measure and a reasonably available control technology analysis; demonstration
of attainment through air dispersion modeling; a control strategy demonstration; an emissions
inventory; a demonstration of reasonable further progress; and contingency measures.
The control measures and contingency measures that were identified for the Collin County Lead
Attainment Demonstration SIP revision were made enforceable through Agreed Order No. 20110521-MIS between the commission and Exide. The Agreed Order provided that enforceable
measures be implemented to reduce lead emissions in the Collin County lead nonattainment
area as soon as possible, but no later than January 6, 2014. The SIP revision and Agreed Order
contained contingency measures designed to ensure continued compliance with the standard.
On June 4, 2012, the City of Frisco and Exide approved an agreement involving the sale of
approximately 180 acres of undeveloped land surrounding Exide's plant. Under the terms of the
agreement, the land around Exide’s plant would be purchased by the Frisco Community
Development Corporation and the Frisco Economic Development Corporation. The agreement
stipulates that Exide will retain ownership of the federal and state permitted plant site and that
Exide will retain responsibility for cleaning up the permitted plant site. The SIP revision and
Agreed Order were revised on August 8, 2012 to reflect this agreement.
Instead of implementing control measures identified in the SIP revision and Agreed Order for
continued operation, per Exide’s agreement with the City of Frisco, Exide chose the option to
close the plant and cease all production activities. Effective November 1, 2012, Exide began
curtailing certain recycling operations and all recycling operations ceased operation on
November 30, 2012. The facility is now permanently shut down. Decontamination and
demolition of Exide’s lead recycling facility was completed on August 15, 2013. Soil remediation
activities at the plant site and surrounding property are still being conducted.
Compliance with the 2008 lead NAAQS is based on 36 three-month rolling averages. For an
ambient air monitoring site to meet this standard, no three-month rolling average for the
previous 36 months prior to the attainment date may exceed 0.15 μg/m3. The EPA’s deadline for
Collin County to attain the 2008 lead NAAQS was as expeditiously as practicable, but no later
than December 31, 2015. Between January 1, 2013 and December 31, 2015, all three-month
rolling averages were below the lead NAAQS at all of the four ambient air monitoring sites
located around the Exide property. Therefore, the area achieved compliance of the 2008 lead
NAAQS as of December 31, 2015. Appendix B: Monitoring Data from Collin County Lead
Monitors describes available monitoring data in Collin County for the years 2013 through 2015.

CHAPTER 2: REDESIGNATION REQUIREMENTS
Section 107(d)(3)(E) of the Federal Clean Air Act (FCAA) states that an area can be redesignated
to attainment if all of the following conditions are met:
1. The Environmental Protection Agency (EPA) has determined that the National Ambient Air
Quality Standards (NAAQS) have been attained.
2. The applicable implementation plan has been fully approved by the EPA under the FCAA,
Section 110(k).
3. The EPA has determined that the improvement in air quality is due to permanent and
enforceable reductions in emissions.
4. The EPA has fully approved a maintenance plan, including a contingency plan, for the area
under Section 175A of the FCAA.
5. The state has met all applicable requirements for the area under the FCAA, Section 110 and
Part D.
2.1 ATTAINMENT OF THE 2008 LEAD NAAQS
2.1.1 Lead Data
The Collin County lead monitoring network consists of four regulatory lead ambient air quality
monitors, two collocated lead ambient air quality monitors, and a meteorological station. The
location of the four regulatory lead monitors is shown in Figure 2-1: Map of Collin County
Regulatory Lead Monitoring Locations.
Data from these monitors are used to determine the area’s compliance with the 2008 lead
NAAQS. Further information regarding the Collin County ambient air monitors can be found in
Chapter 5: Monitoring Network. Compliance with the 2008 lead NAAQS is based on 36 threemonth rolling averages. According to 40 Code of Federal Regulations Part 50, Appendix R, the
2008 lead NAAQS is met at a monitoring site when the identified design value is valid and is less
than or equal to 0.15 micrograms per cubic meter (μg/m3). A lead design value that meets the
NAAQS is considered valid if it encompasses 36 consecutive, valid three-month site means.
Between January 1, 2013 and December 31, 2015, there was not a three-month rolling average
above the lead NAAQS at any of the four monitoring sites. The current design value is 0.08
µg/m3 as of December 31, 2015. Table 2-1: Collin County Lead Design Value Summary 20132015 shows the annual maximum three-month rolling averages for all four monitors for 20132015. Thus, the area achieved compliance of the 2008 lead NAAQS by December 31, 2015.

2.1.2 Lead Trend Analysis
Figure 2-2: Collin County Design Value Trends 2000-2015 shows the lead design values for
each of the four regulatory monitors located in the nonattainment area. To provide some
additional insight into the data represented in Figure 2-2, the design value listed for each year is
actually the highest design value taken over a three year period. For example, at the Frisco
Eubanks monitor the listed design value for 2014 was 0.31 µg/m3. This is the highest design
value over the 2012, 2013, and 2014 period. The 0.31 µg/m3, which is a three month average,
actually occurred in October of 2012 and was the average of the sampling results for the months
of August, September, and October 2012. As a result of Exide Technologies (Exide) permanently
shutting down on November 30, 2012, the design values of the four monitors began rapidly
decreasing. By the end of 2015 (years 2013, 2014, and 2015), data from all four monitoring sites
are in attainment of the 2008 lead NAAQS, with a design value of 0.08 µg/m3.

2.2 SIP APPROVABILITY UNDER SECTION 110(K) OF THE FCAA
To qualify for redesignation, the state implementation plan (SIP) revision for the Collin County
area must be fully approved under Section 110(k). This section of the FCAA contains the
requirements for SIP completeness; deadlines; full, partial and conditional approval; and
disapproval. Approval of the required SIP elements and the redesignation request may occur
simultaneously. 2 An area cannot be redesignated if a required element of its plan is the subject
of a disapproval; a finding of failure to submit or to implement the SIP; or partial, conditional,
or limited approval. This does not mean that earlier issues with regard to the SIP will be
reopened; the SIP must be fully approved only with respect to applicable requirements.
2.2.1 Section 110 General SIP Requirements
Under Section 110(a)(1) and (2) of the FCAA, states are required to submit plans to provide for
the implementation, maintenance, and enforcement of any new or revised NAAQS. Section
110(a)(1) and (2) require states to address basic program elements, including requirements for
emissions inventories, monitoring, and modeling. States are required to submit SIPs to the EPA
that demonstrate that these basic program elements have been addressed within three years of
the promulgation of any new or revised NAAQS.

John Calcagni, Director, Air Quality Management Division, September 4, 1992.

2-4

The EPA revised the lead NAAQS on October 15, 2008, from 1.5 µg/m3, established in 1978, to a
new level of 0.15 µg/m3. In order to comply with requirements under Section 110(a)(1) and (2),
the Texas Commission on Environmental Quality (TCEQ) submitted the Lead Transport Plan
SIP Revision (Project No. 2011-005-SIP-NR), adopted by the commission on August 17, 2011,
and the Lead Infrastructure Demonstration SIP Revision (Project No. 2011-016-SIP-NR),
adopted by the commission on October 5, 2011 to the EPA. The Lead Transport Plan SIP
Revision and the Lead Infrastructure Demonstration SIP Revision were both approved by the
EPA on January 14, 2016.
2.2.2 Part D Requirements
In order for the Collin County area to be redesignated, Texas must also meet all requirements of
Part D of the FCAA that were applicable prior to submittal of the redesignation request.
2.2.2.1 Background
The Collin County nonattainment area for the 2008 lead NAAQS consists of a 1.28 square mile
area surrounding the dismantled Exide lead-acid battery recycling operations in Frisco, Texas.
In addition to permits held by Exide for the secondary lead smelting and lead oxide operations
at the lead-acid battery recycling facility, which have been voided, the TCEQ had control
measures and contingency measures that were enforceable through agreed orders, which were
adopted as part of the 1993 lead SIP for Collin County, the 1999 Collin County Redesignation
and Maintenance Plan for Lead, and the 2009 Collin County Maintenance Plan SIP for lead.
2.2.2.2 Attainment Demonstration
In addition to previous measures to control ambient levels of lead, the Collin County Attainment
Demonstration SIP Revision for the 2008 Lead NAAQS (Project No. 2011-001-SIP-NR) along
with the Agreed Order associated with that SIP revision (Agreed Order 2011-0521-MIS),
contained additional control measures, which demonstrated that the Collin County area would
attain the 2008 lead NAAQS. In addition, the attainment demonstration SIP revision included
the following required Part D elements:





a reasonably available control technology analysis;
a reasonably available control measures analysis;
a demonstration of attainment through dispersion modeling;
a reasonable further progress demonstration;
a contingency plan; and
an emissions inventory for the nonattainment area.

The Collin County Attainment Demonstration for the 2008 Lead NAAQS SIP Revision was
adopted by the commission on August 8, 2012, and was submitted to the EPA on October 10,
2012. The EPA has not yet acted on the approval of this SIP submittal.
Instead of implementing control measures identified in the attainment demonstration SIP
revision and Agreed Order for continued operation, per Exide’s agreement with the City of
Frisco, Exide chose the option to close the plant and cease all production activities. Effective
November 1, 2012, Exide began curtailing certain recycling operations and all recycling
operations ceased operation on November 30, 2012. The facility is now permanently shut down
and as of August 15, 2013, decontamination and demolition of the Exide’s lead recycling facility
was completed. Exide voided its air permits on July 12, 2013. Soil remediation activities at the
plant site and surrounding property are still being conducted.

2.3 SECTION 175A REQUIREMENTS FOR MAINTENANCE PLANS
The remainder of this proposed SIP revision is intended to fulfill the maintenance plan
requirements in Section 175A of the FCAA and contains the following elements:




an attainment emissions inventory;
a maintenance demonstration;
verification of continued attainment;
monitoring network verification; and
a contingency plan.

2-6

CHAPTER 3: ATTAINMENT EMISSIONS INVENTORY
3.1 INTRODUCTION
Section 107(d)(3)(E)(iii) of the Federal Clean Air Act indicates that for an area to be
redesignated to attainment, the improvement in air quality must be due to permanent and
enforceable reductions in emissions. Other emissions inventory related requirements include a
projection of the emissions inventory to a year at least 10 years following redesignation; a
demonstration that the projected level of emissions is sufficient to maintain the annual lead
standard; and a commitment to provide future updates of the inventory to enable tracking of
emission levels during the 10-year maintenance period.
3.2 POINT SOURCES
Stationary point source emissions data are collected annually from sites that meet the reporting
requirements of 30 Texas Administrative Code §101.10. As part of this program, the Texas
Commission on Environmental Quality (TCEQ) compiled emissions inventory data for the
Collin County lead nonattainment area. The Collin County Attainment Demonstration for the
2008 Lead NAAQS relied on a 2010 emissions inventory. This lead emissions inventory for
Collin County consisted of a review of the stationary source emissions from the facilities located
within the nonattainment area. The only facility that produced lead emissions within the
nonattainment area was Exide Technologies (Exide), which in 2010 emitted a total of 1.06 tons
per year (tpy) of lead.

As shown in Table 1: Collin County Lead Emissions Inventory Totals (tpy), lead emissions in
the Collin County nonattainment area decreased to zero tpy by 2013 due to the permanent
shutdown of the Exide facility on November 30, 2012.

CHAPTER 4: MAINTENANCE DEMONSTRATION
4.1 GENERAL
The maintenance plan must demonstrate that the Collin County area will remain in attainment
of the 2008 lead standard for the 10-year period following the date of redesignation to
attainment. Because redesignation of the area to attainment is contingent upon the United
States Environmental Protection Agency’s (EPA) approval of this maintenance plan, the Texas
Commission on Environmental Quality (TCEQ) has set a horizon year of 2028. Setting the
horizon date at 12 years from the time that the maintenance plan must be submitted to the EPA
allows adequate time for review and approval of the plan and redesignation of the Collin County
area to attainment. The maintenance demonstration is satisfied if the state demonstrates that
future lead emission levels are not expected to result in exceedances of the 2008 lead National
Ambient Air Quality Standard.
4.2 FUTURE EMISSIONS AND VERIFICATION OF CONTINUED ATTAINMENT
Maintenance is demonstrated when the future-year projected emission totals measured in tons
per year (tpy) in the horizon year (2028) are at or below the attainment year totals. Due to the
permanent shutdown of Exide Technologies (Exide) on November 30, 2012, lead emissions in
the area have been zero since 2013 and are projected to remain at zero by the horizon year of
2028. Table 4-1: Summary of Future Collin County Lead Emissions (tpy), reflects this trend.
Exide voided their air permits with the TCEQ on July 12, 2013 and demolition and
decontamination of Exide’s operating facility was completed by August 15, 2013. Therefore,
stationary source operations involving lead emissions could not resume without Exide, or any
other company, becoming a new source and being subject to new source review permitting
requirements. This ensures maintenance of the lead standard into the future.

CHAPTER 5: MONITORING NETWORK
5.1 GENERAL
The ambient air quality monitoring network provides data to verify continued attainment of the
lead National Ambient Air Quality Standard. The Collin County lead nonattainment area
monitoring network in 2015 consists of four sites, each with a regulatory ambient air lead
monitor. There are also two collocated monitors and a meteorological station. The Texas
Commission on Environmental Quality (TCEQ) funds and CB&I Environmental operates the
monitors. The area monitoring network includes the Frisco 5th Street (Air Quality System site
identification number (AQS) 480850003), Frisco 7 (AQS 480850007) plus a collocated
monitor, Frisco Eubanks (AQS 480850009) plus a collocated monitor and a meteorological
station, and Frisco Stonebrook (AQS 480850029) sites. The Frisco Eubanks monitor is the
monitor historically driving the area’s design value.
The monitors are managed in accordance with 40 Code of Federal Regulations (CFR) Part 58 to
verify the attainment status of the area. The TCEQ commits to keep in operation an appropriate
air monitoring network in the Collin County area and will continue to work with the United
States Environmental Protection Agency (EPA) through the air monitoring network review
process, as required by 40 CFR Part 58, to determine the adequacy of the lead monitoring
network and when monitoring can be discontinued. Air monitoring data from the monitoring
network will continue to be quality assured according to the requirements in the EPA’s
regulations until the end of the maintenance period (2028) and reported to the EPA on the
schedule required by 40 CFR Part 58. Appendix B: Monitoring Data from Collin County Lead
Monitors describes available monitoring data in Collin County for the years 2013 through 2015.

CHAPTER 6: CONTINGENCY PLAN
6.1 BACKGROUND
Section 175A(d) of the Federal Clean Air Act requires that maintenance plans include
contingency provisions to promptly correct any violation of the National Ambient Air Quality
Standard (NAAQS). The contingency plan ensures that the contingency measures are adopted
expeditiously if they are triggered. In accordance with United States Environmental Protection
Agency (EPA) guidance, a trigger has been established in order to effectuate appropriate and
timely responses to indications of a possible future violation of the NAAQS. Thus, actions may
be taken that can avoid a violation and potential redesignation to nonattainment.
6.2 CONTINGENCY MEASURES AND TRIGGER LEVELS
Since Exide Technologies has permanently shut down, with all of the lead recycling facilities
having been removed from the site, no future air emissions of lead are anticipated to occur.
Therefore, the identification of specific detailed measures is not practical. However, the TCEQ
commits to adopt and expeditiously implement necessary corrective actions in the following
circumstances.
6.2.1 Warning Level Response
A warning level response will be prompted whenever a three-month rolling average
concentration of 0.135 micrograms per cubic meter (µg/m3) of lead, (which is 90% of the
standard) occurs at any of the ambient monitoring sites in the Collin County lead nonattainment
area monitoring network. A warning level response will consist of a study to determine whether
the lead design value indicates a trend toward higher design values. The study will evaluate
whether the trend, if any, is likely to continue and, if so, the measures necessary to reverse the
trend taking into consideration ease and timing for implementation as well as economic and
social considerations. Implementation of necessary measures in response to a warning level
response trigger will take place as expeditiously as possible, but no later than 12 months from
the conclusion of the most recent calendar year.
Should it be determined through the warning level study that action is necessary to reverse the
noted trend, the procedures for measure selection and implementation outlined under “action
level response” will be followed.
6.2.2 Action Level Response
An action level response will be prompted whenever a two-year average of the three-month
rolling average concentration of 0.143 μg/m3 of lead (which is 95% of the standard) or greater
occurs at any of the ambient monitoring sites in the Collin County lead nonattainment area
monitoring network. A violation of the standard (any three-month rolling average that exceeds
0.15 μg/m3) will also prompt an action level response. In the event that the action level is
triggered and is not found to be due to an exceptional event, malfunction, or noncompliance
with a permit condition (if a permit exists), or rule requirement, the TCEQ, in conjunction with
the entity/entities believed to be responsible for the exceedance, will evaluate additional
measures needed to assure future attainment of the lead NAAQS. In this case, measures that can
be implemented in a short time will be selected in order for the measures to be in place within
18 months from the close of the calendar year that prompted the action level. The TCEQ will also
consider the timing of an action level trigger and determine if additional, significant new
regulations not currently included as part of the maintenance provisions will be implemented in
a timely manner and will constitute the TCEQ’s response.

6-1

6.2.3 Control Measure Selection and Implementation
Adoption of any additional control measures into the Texas state implementation plan is subject
to the administrative and legal processes required by state and federal law. This process would
include publication of notices, an opportunity for public hearing, and other measures required
by Texas law for rulemaking or permitting.
If a new measure/control is already promulgated and scheduled to be implemented at the
federal or state level, and that measure/control is determined to be sufficient to address the
upward trend in air quality, additional local measures may be unnecessary. Furthermore, the
TCEQ will submit to the EPA an analysis to demonstrate the proposed measures are adequate to
return the area to attainment.
