The Division of Surface Water (DSW) develops and enforces rules in the Ohio Administrative Code (OAC).
Ohio EPA surface water quality protection and wastewater pollution control regulations are located in OAC Chapters 3745-1 to 3745-5, 3745-11, 3745-32 to 3745-33, 3745-36, 3745-38 to 3745-40, and 3745-42. Additional chapters are added as needed to address new laws and requirements related to surface waters.

Proposing new rules and amending existing rules is a regular activity conducted by Ohio EPA in response to laws passed by the Ohio General Assembly and federal rule requirements. DSW is required by federal law to review water quality standards regulations every three years and by state law to review rules at least once every five years to ensure their continued need and relevance.
Links to outside sites which may be of use to individuals interested in rules or the rule-making process include the Register of Ohio, which contains all state agency rule proposal packages and the Joint Committee on Agency Rule Review, which is the legislative committee responsible for the review and processing of all state agency rules.
All State of Ohio rules and regulations are available online through Ohio's Official Online Publication of State Laws and Regulations.
