These checklists were developed to assist TCEQ staff in preparing for and conducting investigations related to specific rules, regulations, and permits. The checklists are only intended as a guide to prompt investigators to consider the requirements in a consistent manner. Additional requirements can be reviewed and may lead to violations not mentioned on the checklist. These checklists are not a substitute for, nor are they intended to be a substitute for, permit terms or rules applicable to owners or operators. Checklists do not contain all of the applicable regulatory requirements as permit terms and rules often impose additional regulatory requirements.
