Synopsis of specific rules from air permitting that were in effect on this date.

Subchapter G Flexible Permits

§ 116.710 Applicability
§ 116.711 Flexible Permit Application
§ 116.714 Application Review Schedule
§ 116.715 General and Special Conditions

116.710 Applicability

(a) Flexible permit. A person may obtain a flexible permit which allows for physical or operational changes as provided by this subchapter as an alternative to obtaining a new source review permit under § 116.110 of this title (relating to Applicability), or in lieu of amending an existing permit under § 116.116 of this title (relating to Amendments and Alterations). A person may obtain a flexible permit pursuant to § 116.711 of this title (relating to Flexible Permit Application) for a facility, group of facilities, or account before any actual work is begun, provided however:

(1) only one flexible permit may be issued at an account site;

(2) modifications to existing facilities covered by a flexible permit may be handled through the amendment of an existing flexible permit;

(3) permitting of a new facility may be handled through the amendment of a flexible permit; and

(4) a flexible permit may not cover sources at more than one account site.

(b) Operations certification. Any person who obtains a flexible permit under this subchapter shall comply with § 116.110(b) of this title.

(c) Change in ownership. The new owner of a facility, group of facilities, or account shall comply with § 116.110(c) of this title, provided however, that all facilities covered by a flexible permit must change ownership at the same time and to the same person, or both the new owner and existing permit holder must obtain a permit alteration allocating the emission caps or individual emission limitation prior to the transfer of the permit by the Texas Natural Resource Conservation Commission (TNRCC). After the sale of a facility or facilities, but prior to the transfer of a permit requiring a permit alteration, the original permit holder remains responsible for ensuring compliance with the existing flexible permit and all rules and regulations of the TNRCC.

(d) Submittal under seal of registered professional engineer. All applications for a flexible permit or flexible permit amendment shall comply with § 116.110(d) of this title.

(e) Responsibility for flexible permit application. The owner of the facility, group of facilities, or account or the operator of the facility, group of facilities, or account who is authorized to act for the owner is responsible for complying with this section, except as provided by subsection (c) of this section.

116.711 Flexible Permit Application

Any application for a new flexible permit or flexible permit amendment must include a completed Form PI-1 General Application. The Form PI-1 must be signed by an authorized representative of the applicant. The Form PI-1 specifies additional support information which must be provided before the application is deemed complete. In order to be granted a flexible permit or flexible permit amendment, the owner or operator of the proposed facility shall submit information to the Texas Natural Resource Conservation Commission (TNRCC) which demonstrates that all of the following are met.

(1) Protection of public health and welfare. The emissions from the proposed facility, group of facilities, or account as determined pursuant to § 116.716 of this title (relating to Emission Caps and Individual Emission Limitations), will comply with all rules and regulations of the TNRCC and with the intent of the Texas Clean Air Act, including protection of the health and physical property of the people. In considering the issuance of a flexible permit for construction or modification of any facility, group of facilities, or account within 3,000 feet or less of an elementary, junior high/middle, or senior high school, the TNRCC shall consider any possible adverse short-term or long-term side effects that an air contaminant or nuisance odor from the facility, group of facilities, or account may have on the individuals attending these school facilities.

(2) Measurement of emissions. The proposed facility, group of facilities, or account will have provisions for measuring the emission of air contaminants as determined by the Executive director. This may include the installation of sampling ports on exhaust stacks and construction of sampling platforms in accordance with guidelines in the TNRCC "Compliance Sampling Manual."

(3) Best Available Control Technology (BACT). The proposed facility, group of facilities, or account will utilize BACT, with consideration given to the technical practicability and economic reasonableness of reducing or eliminating the emissions from the facility on a proposed facility, group of facilities, or account basis. Control technology beyond BACT may be used on certain facilities to provide the emission reductions necessary to comply with this requirement on a group of facilities or account basis, provided however, that the existing level of control may not be lessened for any facility. For new facilities, the use of BACT shall be demonstrated for the individual facility.

(4) Federal New Source Performance Standards (NSPS). The emissions from each affected facility as defined in 40 Code of Federal Regulations (CFR) Part 60 will meet at least the requirements of any applicable NSPS as listed under Title 40 CFR Part 60, promulgated by the United States Environmental Protection Agency (EPA) pursuant to authority granted under the Federal Clean Air Act (FCAA), § 111, as amended.

(5) National Emission Standards for Hazardous Air Pollutants (NESHAPS) and Maximum Achievable Control Technology (MACT). The emissions from each facility as defined in 40 CFR Part 61 will meet at least the requirements of any applicable NESHAPS, as listed under 40 CFR Part 61, or any MACT standard, promulgated by EPA pursuant to authority granted under the FCAA, § 112, as amended.

(6) Performance demonstration. The proposed facility, group of facilities, or account will achieve the performance specified in the flexible permit application. The applicant may be required to submit additional engineering data after a flexible permit has been issued in order to demonstrate further that the proposed facility, group of facilities, or account will achieve the performance specified in the flexible permit. In addition, initial compliance testing with ongoing compliance determined through engineering calculations based on measured process variables, parametric or predictive monitoring, stack monitoring, or stack testing may be required.

(7) Nonattainment review. If the proposed facility, group of facilities, or account is located in a nonattainment area, each facility shall comply with all applicable requirements under the undesignated head concerning nonattainment review in Subchapter B of this chapter.

(8) Prevention of Significant Deterioration (PSD) review. If the proposed facility, group of facilities, or account is located in an attainment area, each facility shall comply with all applicable requirements under the undesignated head concerning PSD in Subchapter B of this chapter.

(9) Air dispersion modeling or ambient monitoring. Computerized air dispersion modeling and/or ambient monitoring may be required by the TNRCC Permits Program to determine the air quality impacts from the facility, group of facilities, or account.

(10) Application content. In addition to any other requirements of this chapter, the applicant shall:

(A) identify each air contaminant for which an emission cap is desired;

(B) identify each facility to be included in the flexible permit;

(C) identify each source of emissions to be included in the flexible permit and for each source of emissions identify the emission point number (EPN) and the air contaminants emitted;

(D) for each emission cap, identify all associated EPNs and provide emission rate calculations based on the expected maximum capacity and the proposed control technology;

(E) for each individual emission limitation, identify the EPN and provide emission rate calculations based on the expected maximum capacity and the proposed control technology.

(11) Proposed control technology and compliance demonstration. The applicant shall specify the control technology proposed for each unit to meet the emission cap and demonstrate compliance with all emission caps at expected maximum production capacity.

116.714 Application Review Schedule

The flexible permit application will be reviewed by the Texas Natural Resource Conservation Commission in accordance with § 116.114 of this title (relating to Application Review Schedule).

116.715 General and Special Conditions

(a) Flexible permits may contain general and special conditions. The holders of flexible permits shall comply with any and all such conditions. Upon a specific finding by the executive director that an increase of a particular air contaminant could result in a significant impact on the air environment, or could cause the facility, group of facilities, or account to become subject to review under the undesignated headings of Subchapter B of this chapter (relating to Nonattainment Review or Prevention of Significant Deterioration Review), the permit may include a special condition which requires the permittee to obtain written approval from the executive director before constructing a facility under a standard exemption or standard permit.

(b) A pollutant specific emission cap or multiple emission caps and/or individual emission limitations shall be established for each air contaminant for all facilities authorized by the flexible permit.

(c) The following general conditions shall be applicable to every flexible permit.

(1) Voiding of permit. A flexible permit or flexible permit amendment under this subchapter is automatically void if the holder fails to complete construction as specified in the flexible permit. Upon request, the executive director may grant a one time 12-month extension of the date to complete construction. This section does not apply to physical or operational changes allowed without an amendment under § 116.721 of this title (relating to Amendments and Alterations).

(2) Construction progress. The start of construction, construction interruptions exceeding 45 days, and completion of construction shall be reported to the appropriate regional office of the Texas Natural Resource Conservation Commission (TNRCC or commission) not later than 15 working days after occurrence of the event.

(3) Start-up notification. The appropriate Air Program Regional Office of the TNRCC and any local program having jurisdiction shall be notified prior to the commencement of operations of the facilities authorized by the permit in such a manner that a representative of the TNRCC may be present. Phased construction, which may involve a series of facilities commencing operations at different times, shall provide separate notification for the commencement of operations for each facility.

(4) Sampling requirements. If sampling of stacks or process vents is required, the flexible permit holder shall contact the Source and Mobile Monitoring Section of the TNRCC Office of Air Quality prior to sampling to obtain the proper data forms and procedures. All sampling and testing procedures must be approved by the executive director and coordinated with the appropriate Air Program Regional Office of the TNRCC. The flexible permit holder is also responsible for providing sampling facilities and conducting the sampling operations or contracting with an independent sampling consultant.

(5) Equivalency of methods. It shall be the responsibility of the flexible permit holder to demonstrate or otherwise justify the equivalency of emission control methods, sampling or other emission testing methods, and monitoring methods proposed as alternatives to methods indicated in the conditions of the flexible permit. Alternative methods shall be applied for in writing and must be reviewed and approved by the executive director prior to their use in fulfilling any requirements of the permit.

(6) Recordkeeping. A copy of the flexible permit along with information and data sufficient to demonstrate continuous compliance with the emission caps and individual emission limitations contained in the flexible permit shall be maintained in a file at the plant site and made available at the request of personnel from the TNRCC or any air pollution control program having jurisdiction. For facilities that normally operate unattended, this information shall be maintained at the nearest staffed location within Texas specified by the permit holder in the permit application. This information may include, but is not limited to, emission cap and individual emission limitation calculations based on a 12-month rolling basis and production records and operating hours. Additional recordkeeping requirements may be specified in special conditions attached to the flexible permit. Information in the file shall be retained for at least two years following the date that the information or data is obtained.

(7) Maximum allowable emission rates. A flexible permit covers only those sources of emissions and those air contaminants listed in the table entitled "Emission Sources - Emissions Caps and Individual Emission Limitations" attached to the flexible permit. Flexible permitted sources are limited to the emission limits and other conditions specified in the table attached to the flexible permit.

(8) Emission cap readjustment. If a schedule to install additional controls is included in the flexible permit and a facility subject to such a schedule is taken out of service, the emission cap contained in the flexible permit will be readjusted for the period the unit is out of service to a level as if no schedule had been established. Unless a special provision specifies the method of readjustment of the emission cap, a permit alteration shall be obtained.

(9) Maintenance of emission control. The facilities covered by the flexible permit shall not be operated unless all air pollution emission capture and abatement equipment is maintained in good working order and operating properly during normal facility operations. Notification for upsets and maintenance shall be made in accordance with § 101.6 and § 101.7 of this title (relating to Notification Requirements for Major Upset and Notification Requirements for Maintenance).

(10) Compliance with rules. Acceptance of a flexible permit by a permit applicant constitutes an acknowledgment and agreement that the holder will comply with all Rules, Regulations, and Orders of the Commission issued in conformity with the Texas Clean Air Act and the conditions precedent to the granting of the permit. If more than one state or federal rule or regulation or flexible permit condition are applicable, then the most stringent limit or condition shall govern and be the standard by which compliance shall be demonstrated. Acceptance includes consent to the entrance of Commission employees and agents into the permitted premises at reasonable times to investigate conditions relating to the emission or concentration of air contaminants, including compliance with the flexible permit.

(d) There may be additional special conditions attached to a flexible permit upon issuance or amendment of the permit. Such conditions in a flexible permit may be more restrictive than the requirements of Title 30 of the Texas Administrative Code.
