TCEQ Rules Archive
A repository for historical rules.
The TCEQ Rules Archive includes rule documents from 1996 to the present.
For current rulemakings, please visit the Rule and Non-Rule Tracking Application. To browse archived documents, use the menu below, organized by fiscal year (Sept. 1-Aug. 31) in which the rule was initiated.
To find a particular rule's project number, find the adopted/effective date on the individual history page (abbreviated as HIS; it lists each revision to a chapter) at TCEQ Rules in PDF. Then, look below for the fiscal year for that particular project to locate the corresponding rule project number. Click to bring up the menu of proposals and adoptions--indicated either by a "pro" or "ado" designation.
