  (4) any individual facility, source, or group of facilities or sources which the executive director determines to be de minimis based upon:

    (A) proximity to receptors;

    (B) rate of emission of air contaminants;

    (C) engineering judgment and experience; and

    (D) determination that no adverse toxicological or health effects would occur off property.

(b) De minimis facilities or sources at a site which are subsequently determined by the executive director to be in violation of any commission rule, permit, order, or statute within the commission's jurisdiction, will no longer be considered de minimis and must obtain registration or authorization under this chapter or Chapter 106 of this title (relating to Permits by Rule).

(c) The "List of De Minimis Facilities or Sources" will be maintained in the commission's Office of Permitting, Remediation, and Registration in Austin, with copies maintained in the commission's regional offices, and on the commission's home page on the World Wide Web.

  (1) Persons may petition the executive director to amend the "List of De Minimis Facilities or Sources" or the executive director may amend the list as necessary.

  (2) When amending the list to add or delete categories of facilities, sources, or groups of facilities or sources, the executive director will consider, at a minimum, the following:

    (A) typical operating scenarios;

    (B) typical design and location;

    (C) the types and rates of air contaminants emitted;

    (D) engineering judgment and experience; and

    (E) toxicological or health impacts.

  (3) When amending the list to add or delete categories of facilities, sources, or groups of facilities or sources, the executive director will publish notice of the proposed amendment on the commission's home page on the World Wide Web and will allow 30 days for comments. If a category of facilities, sources, or groups of facilities or sources is deleted from the list, the owner or operator will have 180 days from the date of publication of the amended list on the commission's home page on the World Wide Web to obtain, register, or apply for authorization under this chapter or Chapter 106 of this title (relating to Permits by Rule).
