The public will have an extra month to comment on proposed changes to state’s Hydraulic Code rules, which regulate construction and other work in or near state waters to protect fish life.

Common projects requiring approval under the state’s hydraulic rules include work on bulkheads, culverts, piers and docks.

The Washington Department of Fish and Wildlife (WDFW) will now accept public comments through Sept.15 on both the proposed rule changes and on an associated environmental impact statement.

Randi Thurston, WDFW program manager, said the department agreed to extend the comment period to give the public more time to review both documents.

All related documents are available on WDFW’s website at wdfw.wa.gov/licensing/hpa/rulemaking/, along with an email address for submitting comments. Written comments also can be addressed to Randi Thurston, WDFW Habitat Program, 600 Capitol Way North, Olympia, WA  98501-1091.

Thurston said the changes proposed by WDFW, the first comprehensive update since 1994, are designed to provide more protection for fish, streamline the permit process and ensure the code is consistent with other state laws.

The Washington Fish and Wildlife Commission, a citizen panel appointed by the Governor to set WDFW policies, is expected to consider adoption of the updated rules later this year.
