Rulemaking
TMDL development and implementation is a public process. DEQ will develop this TMDL by rule per
Oregon Administrative Rule Chapter 340 Division 42. During a rulemaking process, DEQ seeks public involvement by holding public hearings, establishing rule advisory committee meetings for technical and policy input, and for feedback regarding potential fiscal impacts related to the rule.
Lower Columbia-Sandy Subbasin TMDL rulemaking
DEQ will hold two rule advisory committee meetings and a public hearing. DEQ will present the draft TMDL and Water Quality Management Plan to the Environmental Quality Commission, DEQ's formal policy and rulemaking body, for adoption in November 2023 before submitting the TMDL to EPA for approval or disapproval.
Please visit the rulemaking web page for rule advisory committee meeting dates and information, draft project documents including the TMDL, Water Quality Management Plan, Technical Support Document, and Fiscal Impact Statement, and to sign up for email updates.
