Utah Admin. Code 315-124-13
Each person, including applicants, who believe any condition of a draft permit is inappropriate or that the director's tentative decision to deny an application, terminate a permit, or prepare a draft permit is inappropriate, shall raise any reasonably ascertainable issues and submit each reasonably available argument supporting their position by the close of the public comment period, including any public hearing, under Section R315-124-10. Any supporting materials that are submitted shall be included in full and may not be incorporated by reference, unless they are already part of the administrative record in the proceeding, or consist of state or federal statutes and regulations, EPA or division documents of general applicability, or other generally available reference materials. Commenters shall make supporting materials not already included in the administrative record available to the director as directed by the director and consistent with Section R305-7-209. A comment period longer than 45 days may be necessary to give commenters a reasonable opportunity to comply with the requirements of Section R315-124-13. Additional time shall be granted under Section R315-124-10 to the extent that a commenter who requests additional time demonstrates the need for additional time.
