April 26, 2017 7PM-9PM  PUBLIC HEARING

Garrett College Career Technology Center

Public Hearing for Texas Eastern Transmission Natural Gas Compressor Station Renewal Title V/ Part 70 Air Operating Permit. 

The Public Hearing will begin promptly at 7:00PM. This is a public hearing being held for the purpose of taking testimony on the draft Title V operating permit for the Texas Eastern facility.  It is not an Informational Meeting, so there will not be an opportunity for questions to be asked during the hearing.  Although the Department’s oversight of Texas Eastern’s Accident facility is limited to matters involving air pollution, the Department will make every effort to respond in writing to comments received at the public hearing or to comments received later in writing from the public that focus on issues not related to the Department’s regulatory authority.

The Renewal Title V Application can be viewed here, with Addendum 1 here, and Addendum 2 here.  

The draft permit conditions can be viewed here and the Fact Sheet can be viewed here.

For informational purposes only, an example of a Mining Program permit for the operation of a natural gas well for Texas Eastern can be viewed here.  Please note, this permit is not part of the Air Quality Title V/ Part 70 Operating Permit, therefore the conditions contained within will not be included in the Title V permit.

CPCN Waivers for New Electric Generation (Effective February 16, 2015).

Effective February 16, 2015 the Public Service Commission (PSC) adopted regulations that increase the threshold for a waiver for a Certificate of Public Convenience and Necessity (CPCN) exemption for electric generators from greater than 1500 kilowatts (kW), to greater than 2000 kilowatts (kW). In accordance with the new PSC regulations, applicants proposing to install a new electric generator rated at 2000 kW or less will no longer be required to obtain a CPCN waiver prior to obtaining an Air Quality Permit to Construct from the Air and Radiation Management Administration.

Please note, the threshold for obtaining permits to construct for electric generators remains unchanged at 373 kw or greater. Questions pertaining to this change may be directed to David Mummert, Chief, Technical Support, at, or at 410-537-3230.


Public Participation Opportunities, APA Permits

Permit applications with expanded public review, known as APA Permits, go through several steps during the permitting process. The complete list of the Air Quality Permit issuance steps for these permits can be found here.

This is a brief description:

  • The firs step in the permit issuance process is the opportunity for interested parties to request an Informational Meeting, which would be held early in the permit application review, prior to an in-depth technical review. It provides the public an opportunity to learn about a proposed project from the applicant, and learn more about the permit process from the Department.
  • The second step in the permit issuance process is the Tentative Determination. Once the Department reaches a Tentative determination, the public is invited to review the draft permit and submit comments, or request a public hearing.
  • After the public hearing, if one is held, and after the comment period has expired, the Department will review all comments received and incorporate changes to the draft permit as necessary, and a Final Determination will be reached. If the Department determines that a proposed permit can be issued, citizens have 30 days from the issuance of the permit to object. The objection must be filed in the county where the proposed project will be located.


Alternate Public Review Procedures for Certain Sources Subject to New Source Performance Standards (NSPS)

House Bill 95, which took effect on October 1, 2013, established an alternate public review procedure for sources subject to public review only because they trigger EPA's New Source Performance Standards (NSPS). Examples include: engines that are not emergency generators, small combined heat and power facilities, peak shavers, and boilers less than 50 MMbtu/hr that are not covered under an Air Quality General Permit to Construct.  The Department will accept comments on these permit applications. 

List of Public Participation Opportunities 

Please see the Public Participation opportunities page here for current opportunities to review and comment on permit applications including Alternate NSPS draft permits, scheduled informational meetings and public hearings, and review Final Determinations.
