Areas formally declared in violation of the NAAQS and adjacent contributing areas are
designated "nonattainment areas." Nonattainment areas must meet certain Clean Air Act
requirements, such as:
Transportation Conformity - Requires a demonstration that regional long-range transportation plans will not negatively impact air quality, or federal transportation funds can be withheld.
New Source Review - Requires a review of new or expanded industrial operations to minimize air pollution.
Rate of Progress Requirements - A certain percentage of pollutants must be reduced each year.
Specific attainment date - Consequences of failure to reach attainment by the specified date include stricter control measures and the potential for stiff penalties.
10-year maintenance plan - Includes additional or continuing mandatory programs for 10 years following attainment.
Another requirement obligates the state to develop and implement a prescriptive comprehensive
clean air plan that mandates how the area will come into compliance with the standard. This
plan and any revisions to it are known as the State Implementation Plan (SIP).
The 1-Hour Standard in Central Texas
An area must have a monitored hourly peak ozone concentration below 125 parts per billion (ppb) to meet the 1-hour ozone standard. If an area exceeds the standard more than three times in three years, it is subject to a nonattainment designation. The Austin/San Marcos Metropolitan Statistical Area (MSA) has not exceeded the 1-hour standard since 1985.
The O3 Flex Agreement
In order to ensure continued attainment of the 1-hour ozone standard, the region's leaders signed an air quality improvement plan called the Ozone Flex Agreement (O3 Flex) in March of 2002. Elected officials and community leaders in Travis, Williamson, Hays, Bastrop and Caldwell counties entered into this agreement with EPA and the Texas Commission on Environmental Quality (TCEQ), formerly the Texas Natural Resource Conservation Commission, to proactively reduce ozone precursor emissions in their own operations. While O3 Flex requires community education and outreach, it imposes no mandatory requirements on
the general public.
The 8-Hour Standard in Central Texas
During the past several years, air quality planning in the Austin region has intensified as ozone concentrations have exceeded the value permitted by the 8-hour ozone NAAQS. Due to legal challenges to the new NAAQS and ensuing litigation, EPA has not formally designated any areas of the United States in violation of the 8-hour ozone NAAQS. The 8-hour NAAQS has been upheld by the Supreme Court and EPA anticipates nationwide designation of nonattainment areas in 2004.. Based on recent monitoring data, it is probable that the Austin/San Marcos MSA will be designated a nonattainment area when formal designations
occur.
The 8-hour ozone standard is found by averaging three years of the fourth highest 8-hour ozone levels in an area. This number, called the design value, must be lower than 85 parts per billion (ppb) to meet the standard. Currently, the Austin/San Marcos MSA design value (averaging 1999, 2000, and 2001) is 88 ppb. Each year this design value will change slightly. Despite annual fluctuations in the design value, elected officials and the citizens of the region understand that long-term air quality will not improve without a concerted emission-reduction effort. The Early Action Compact (EAC) is the region's response.
Protocol for Early Action Compacts
EPA Region 6 endorsed the TCEQ Protocol for Early Action Compacts (EAC Protocol) on June 19, 2002. It establishes a two-step process that offers a more expeditious time line for achieving clean air than expected under EPA's 8-hour implementation rulemaking. The EAC Protocol allows a region to enter into a memorandum of agreement (MOA) by December 31, 2002, committing to develop and implement a detailed technical plan to reach attainment by 2007 The principles of the EAC Protocol to be executed by Local, State and EPA officials are:
Early planning, implementation, and emission reductions leading to expeditious attainment and maintenance of the 8-hour ozone standard;
Local control of the measures to be employed, with broad-based public input;
State support to ensure technical integrity of the early action plan;
Formal incorporation of the early action plan into the SIP;
Deferral of the effective date of nonattainment designation and related requirements so long as all terms and milestones are met; and
Safeguards to return areas to traditional SIP requirements should terms and/or milestones be unfulfilled, with appropriate credit given for emission reduction measures implemented.
The Austin/San Marcos MSA Response
The region is volunteering to participate in the EAC Protocol process to expedite air cleanup for
future public health and welfare. The Austin/San Marcos MSA Response has two components:
1. The Early Action Compact (EAC) - The EAC is a Memorandum of Agreement to prepare and implement the Clean Air Action Plan. More specifically, the EAC sets measurable, enforceable milestones for developing and implementing the Clean Air Action Plan.
2. The Clean Air Action Plan (CAAP) - The CAAP serves as the region's official air quality improvement plan, with quantified emission-reduction measures. The CAAP will include all necessary elements of a comprehensive air quality plan, (like the plans in Dallas or Houston), but will be tailored to local needs and driven by local decisions. Moreover, the CAAP will be incorporated into the formal SIP and the region will be legally required to carry out this plan just as in nonattainment areas. For example, development of the CAAP will require the same scientific diligence and undergo the same scrutiny as the nonattainment areas' SIPs, so that the emission reduction strategies selected will be adequate to ensure the region stays in attainment of the 8-hour standard.
EAC Protocol Versus Traditional Nonattainment
A major advantage of the region's participation in the EAC Protocol is the flexibility afforded to the signatories in selecting emission reduction measures and programs that are best suited to local needs and circumstances. Recognizing the varied socioeconomic and emissions characteristics within the region, not all measures can or should be implemented by every entity.
The primary differences between the process outlined in the EAC Protocol and the traditional nonattainment area process are:
EAC Protocol is designed to achieve clean air sooner than expected under the traditional nonattainment process .
EAC Protocol allows for more local control in selecting emission-reduction measures.
EAC Protocol ensures deferral of the effective date of nonattainment designation and related requirements, as long as EAC terms and milestones are met. This would alleviate any stigma associated with a nonattainment designation.
Should any milestones be missed in designing or implementing the CAAP, the region would automatically revert to the traditional nonattainment requirements, with appropriate credit given for emission reduction strategies already implemented.
EAC Protocol Versus O3 Flex
The EAC Protocol specifically addresses the 8-hour standard and will build on the emission
reduction strategies outlined in the O3 Flex Agreement. However, the strategies needed to attain
the 8-hour standard likely will affect more people than those outlined in the O3 Flex Agreement,
since the 8-hour standard is generally more difficult to achieve.
EAC Protocol Timeline
The Austin/San Marcos MSA EAC is designed to enable a local, proactive approach to ensuring
attainment of the 8-hour ozone NAAQS, and so protect human health. Using the EAC Protocol,
the region could implement emission reduction measures by 2005 that are directed at attaining
the 8-hour standard by 2007. This allows for a significantly earlier start than waiting for formal
EPA nonattainment designation and it gives the local area more flexibility in choosing which
emission reduction strategies to implement in order to achieve attainment of the 8-hour ozone
NAAQS.
The Area Encompassed by the EAC
The Austin/San Marcos MSA, which comprises Travis, Williamson, Hays, Bastrop and Caldwell
Counties, is the planning area for which this EAC is designed. This is the same area
encompassed by the O3 Flex Agreement.
Signatories and Their Responsibilities
The individuals representing the entities that will sign this EAC are: the County Judges for
Bastrop, Caldwell, Hays, Travis and Williamson Counties; the mayors for the cities of Austin,
Bastrop, Elgin, Lockhart, Luling, Round Rock and San Marcos; and appropriate signatories from
EPA and TCEQ. The local entities whose representatives support and sign the EAC are
committed to holding primary responsibility for the development and implementation of the
CAAP, and for maintaining communication with all parties. These commitments by local
agencies are enumerated in the following Memorandum of Agreement, along with the
commitments of TCEQ and EPA.
Conditions for Modification or Early Termination
This agreement may be modified or terminated at any time by mutual consent of all signatory
parties before formal incorporation into the SIP in 2004. Before the CAAP is adopted into the
SIP, any signatory party may withdraw from the agreement. If a party's withdrawal from the
agreement prevents remaining signatories from satisfying any of the terms and milestones of
the original agreement, the agreement will be void and the area's nonattainment designation
immediately effective. Once the CAAP is incorporated into the SIP, modification is considerably
more difficult, as the SIP is a legally binding state and federal agreement to carry out specific
emission-reduction activities.
Austin/San Marcos Metropolitan Statistical Area Early Action Compact
Memorandum of Agreement
This Early Action Compact (EAC) is a Memorandum of Agreement between the local
governments representing Bastrop, Caldwell, Hays, Travis and Williamson counties and the
cities of Austin, Bastrop, Elgin, Lockhart, Luling, Round Rock and San Marcos (collectively, the
local governments), the Texas Commission on Environmental Quality (TCEQ) and the United
States Environmental Protection Agency (EPA). It is for the express purpose of developing and
implementing a Clean Air Action Plan (CAAP) that will reduce ground-level ozone concentrations in
the Austin/San Marcos Metropolitan Statistical Area (MSA) to comply with the 8-hour ozone
standard by December 31, 2007, and maintain the standard beyond that date. Failure to meet
these obligations results in immediate reversion to the traditional nonattainment process.
I. General Provisions
A. The signatory parties commit to develop, implement and maintain the CAAP according to EPA Protocol for Early Action Compacts as amended November 21, 2002, and adhere to all terms and conditions stated in the guidelines. See Appendix A for EPA Protocol for Early Action Compacts Designed to Achieve and Maintain the 8-Hour Ozone Standard.
B. If the region does not meet all the terms of the EAC, including meeting agreed-upon milestones, then it will forfeit its participation and may be designated nonattainment according to EPA's 8-hour ozone implementation rules.
C. Before formal adoption into the SIP, this agreement may be modified or terminated by mutual consent of all signatory parties, or any party may withdraw from the agreement. The local government signatories will approve the CAAP before it is submitted to TCEQ for inclusion in the SIP. Once the CAAP is incorporated into the SIP, any modifications will be treated as SIP revisions.
D. The signature date of the EAC is the start date of the agreement's term and the agreement remains in effect until December 31, 2007.
II. Local Government Responsibilities
The local governments agree to develop and implement a CAAP that will demonstrate
attainment by year's end 2007 of the 8-hour ozone standard and maintenance until at least
2012. The local governments will develop this plan in coordination with TCEQ, EPA,
stakeholders and the public. The CAAP will include a process to monitor and maintain long term
compliance with the standard. Local emission reduction strategies being considered for
inclusion into the CAAP will be identified and described by June 16, 2003. The CAAP will be
submitted to TCEQ and EPA for review by January 31, 2004, and finalized by March 31, 2004,
for inclusion in the SIP by December 31, 2004.
In the event a development or issue arises that may impact performance or progress toward
milestones (including if a milestone will be or has been missed and/or if a termination or
modification has been requested), the Capital Area Planning Council (CAPCO) or the signatory
party responsible will notify all other signatories as soon as possible.

2. Reporting
In order to facilitate self-evaluation and communication with EPA, TCEQ, stakeholders, and the public, the region will assess and report progress towards milestones in a regular, public process, at least every six months, beginning in June 2003.
B. Emissions Inventories
1. An initial modeling emissions inventory will be developed by November 30,
2003. This inventory will include:
a. Emissions modeling data for a 1999 or later episode that is representative of a typical ozone season exceedance and meets EPA episode selection guidance;
b. MOBILE6 data with link based Travel Demand Model (TDM) mobile data in urban areas;
c. NONROAD model data adjusted for local equipment populations and usage rates;
d. Area source data, based on local survey data, when possible.
2. A 2007 future year modeling emissions inventory will be developed by December 31, 2003. This inventory will sufficiently account for projected future growth in ozone precursor emissions through 2007, particularly from stationary, non-road and on-road mobile sources
3. One further episode inventory will also be developed to represent the variety of situations that typically contribute to ozone production in the area and to include the most recent emissions modeling methods and data. Additional inventories will be contingent upon legislative appropriations or other funding. Selection of specific episode inventories will be partially determined by the conceptual model, which reflects an analysis of meteorological conditions typical of high ozone events.
a. The conceptual model will be updated by November 30, 2003.
b. A schedule for the development of further episode inventories will be completed by January 31, 2004.
4. Emissions inventories will be compared and analyzed for trends in emission sources over time. The emissions inventory comparison and analysis will be completed by December 31, 2003.
C. Modeling
1. Base case modeling will be completed by November 30, 2003 and future case modeling will be completed by December 31, 2003. One or more modeled control cases will be completed by January 31, 2004, with final revisions completed by March 31, 2004. All modeling:
a. Will be SIP quality and perform within EPA's accepted margin of accuracy;
b. Will be carefully documented;
c. Will sufficiently account for projected future growth in ozone precursor emissions;
d. Will be accomplished with technical support and review by TCEQ and concurrently reviewed by EPA;
e. Will be used to determine the effectiveness of NOx and/or VOC reductions.
The control case(s) will be used to determine the relative effectiveness of
different emission reduction strategies and to aid in the selection of
appropriate emission reduction strategies.
D. Emission Reduction Strategies
1. All adopted Federal and State emission reduction strategies that have been or will be implemented by the December 31, 2007 attainment date will be included in base, future and control case modeling.
2. Additional local emission reduction strategies under consideration for inclusion in the CAAP will be identified and described by June 16, 2003.
3. Local emission reduction strategies needed to demonstrate attainment for the Austin/San Marcos MSA by December 31, 2007 will be selected by January 31, 2004, with final revisions completed by March 31, 2004. The selected local strategies will be implemented as soon as practical, but no later than December 31, 2005.
4. Local emission reduction strategies will be specific, quantified, permanent and enforceable. The strategies will also include specific implementation dates and detailed documentation and reporting processes.
5. Voluntary strategies can play a supporting role in the CAAP. If emission reductions from voluntary strategies are quantified and credit is taken for them in the CAAP, those emission reductions will be enforceable. Additional strategies must be implemented to meet those quantified reduction requirements if quantified voluntary strategies fail. This is true for all quantified emission reductions.
6. Local emission reduction strategies will be designed and implemented by the community with stakeholder participation.
7. Local emission reduction strategies will be incorporated by the state into the SIP.
In the event that the region desires to add, delete or substitute strategies after SIP submittal, the region will request a modification. CAAP modifications will be treated as SIP revisions and facilitated by the state.
E. Maintenance for Growth
1. The CAAP will include a component to address emissions growth at least five years beyond December 31, 2007, ensuring that the area will remain in attainment of the 8-hour standard during that period. Attainment maintenance analysis will be completed by January 31, 2004, with final revisions completed by March 31, 2004. The analysis will employ one or more of the following or any other appropriate techniques necessary to make such a demonstration:
a. Modeling analysis showing ozone levels below the 8-hour standard in 2012;
b. An annual review of growth (especially mobile and stationary source) to ensure emission reduction strategies and growth assumptions are adequate;
c. Identification and quantification of federal, state, and/or local measures indicating sufficient reductions to offset growth estimates.
2. A continuing planning process that includes modeling updates and modeling assumption verification (particularly growth assumptions) will be conducted concurrent with the tracking and reporting process for the CAAP. This update and verification will be an ongoing process between the signatories, stakeholders and the public. Modeling updates and planning processes must consider and evaluate:
a. All relevant actual new point sources;
b. Impacts from potential new source growth; and
c. Future transportation patterns and their impact on air quality in a manner that is consistent with the most current adopted Long Range Transportation Plan and most current trend and projections of local motor vehicle emissions.
3. If the review of emissions growth in conjunction with the continuing planning
process demonstrates that adopted emission reduction strategies are inadequate
to address growth in emissions, additional measures will be added to the CAAP.
4. In the event that the continuing planning process identifies the need to add,
delete, or substitute emission reduction strategies after the CAAP has been
incorporated into the SIP, the local area will initiate, and TCEQ will facilitate a SIP revision to accommodate changes.
F. Public Involvement
1. Public involvement will be conducted in all stages of planning by the signatory parties, with assistance from one or more of the following: The CLEAN AIR Force of Central Texas, CAPCO, Greater Austin Chamber of Commerce, or other appropriate party. Outreach may include one or more of the following techniques: public meetings and presentations, stakeholder meetings, websites, print advertising and radio.
2. Public education programs will be used to raise awareness regarding issues, opportunities for involvement in the planning process, implementation of emission reduction strategies, and any other issues important to the area.
3. Interested stakeholders will be involved in the planning process as early as possible. Planning meetings will be open to the public, with posted meeting times and locations. CAAP drafts will be publicly available, and the drafting process will have sufficient opportunities for comment from all interested stakeholders.
4. Public comment on the proposed final CAAP will follow the normal SIP revision process as implemented by the State.
5. Semi-annual reports detailing, at a minimum, progress toward milestones, will be publicly presented and publicly available.
III. The Texas Commission on Environmental Quality
The state, represented by TCEQ, will provide support to areas throughout the planning and
implementation process, including:
1. Technical assistance in the development of emission inventories, modeling process, trend analysis and quantification and comparison of emission reduction strategies;
2. Necessary information on all Federal and State adopted emission reduction strategies which affect the area;
3. Critical third party review of emissions inventory, modeling, and self-evaluation work;
4. Technical and strategic assistance, as appropriate, in the selection and implementation of emission reduction strategies;
5. Technical and planning assistance in developing and implementing processes to address the impact of emissions growth beyond the attainment date;
6. Maintenance of monitors and reporting and analysis of monitoring data;
7. Support for public education efforts;
8. Coordinate communication between local areas and EPA to facilitate continuing EPA review of local work;
9. Expeditious review of the locally developed CAAP, and if deemed adequate, propose modification of the SIP to adopt the CAAP;
10. Adoption of emission reduction strategies into the SIP as expeditiously as possible. The final complete SIP revision must be completed, adopted, and submitted by the state to EPA by 2004.
IV. The Environmental Protection Agency
1. The EPA will provide technical assistance to the state and local area in the development of the early action plan.
2. The EPA will move quickly to review and approve completed plans by no later than nine months after submission of the SIP revision by the state.
3. When EPA's 8-hour implementation guidelines call for designations, EPA will defer the effective date of nonattainment designation and related requirements for participating areas that fail to meet the 8-hour ozone standard as long as all terms and milestones of the compact are being met, including submission of the early action SIP revision by 2004.
4. Provided that the monitors in the area reflect attainment by December 31, 2007, EPA will move expeditiously to designate the area as attainment and impose no additional requirements.
5. If at any time the area does not meet all the terms of this compact, including meeting agreed-upon milestones, then it will forfeit its participation and its designation(or re-designation if necessary) will become effective according to EPA's 8-hour ozone implementation guidelines. The EPA will offer such an area no delays, exemptions or other favorable treatment because of its previous participation in this program.
6. If the area violates the standard as of December 31, 2007, and the area has had the effective date of its nonattainment designation deferred, the area's nonattainment designation will become effective. The state will then submit a revised attainment demonstration SIP revision according to the Clean Air Act (CAA) and EPA's 8-hour implementation rule, unless the 8-hour implementation schedule requires SIPs from 8-hour nonattainment areas before December 31, 2008. In that event, a revised attainment demonstration SIP revision for the participating area will be due as soon as possible but no later than December 31, 2008. In no event will EPA extend the attainment date for the area beyond that required by the CAA and/or EPA's 8-hour implementation rule.
7. The region will not be allowed to renew this EAC after December 31, 2007, or to initiate a new compact if it has previously forfeited its participation.
