This is in relation to works, undertakings or activities during various phases of their life cycle, such as construction, operation, maintenance or decommissioning.

You may need to request a project review if these standards and code of practices don’t apply or aren’t applicable to your work, undertaking or activity.

View the interim end of pipe fish screens code of practice.

This interim code of practice provides guidance on the design, installation and maintenance of small end-of-pipe water intake fish screens to prevent entrainment and impingement of fish.

The end-of-pipe fish screen code of practice also provides:

This code of practice does not cover impacts related to fish habitat and changes in flow conditions.

Interim code of practice: routine maintenance dredging

View the interim routine maintenance dredging code of practice.

This interim code of practice provides best practices for routine maintenance dredging, which occurs at least once every 10 years.

Routine maintenance dredging involves the mechanical removal of accumulated sediment from the bed of a waterbody. Dredging uses clam buckets, draglines or backhoes and suction.

Routine dredging helps to maintain the design depths of:

The routine maintenance dredging code of practice provides useful information on the measures to follow to ensure that fish and fish habitat are protected. Potential impacts to fish habitat from routine maintenance dredging include:

This code applies to routine maintenance dredging only and does not apply to new dredging projects or to the expansion of a previously dredged area.
