(a) A permit application is administratively complete when:
(1) a complete permit application form and the report and fees required to be submitted with a permit application have been submitted to the commission; and
(2) the permit application is ready for technical review in accordance with the rules of the commission.
(b) Once a determination that an application is administratively and technically complete has been made and the permit application has become the subject of a contested case under Section 2001.003, Government Code:
(1) the commission may not revoke the determination that an application is administratively or technically complete;
(2) the commission may request additional information from the applicant only if the information is necessary to clarify, modify, or supplement previously submitted material provided that all parties may engage in discovery against all other parties, as provided by applicable law; and
(3) a request for additional information does not render the application incomplete.
(c) Subsection (b) does not:
(1) preclude an informal disposition of a contested case by stipulation, agreed settlement, consent order, or default; or
(2) restrict the right of any party to conduct discovery against any applicable party under other law.
