Who can certify an erosion and sediment control plan in Queensland?

It depends on the site's erosion hazard rating. Brisbane City Council, for example, requires that on sites where the erosion hazard is assessed as high risk, the erosion and sediment control plan is certified by a CPESC. For lower-risk sites, an appropriately qualified person, a CPESC or a Registered Professional Engineer of Queensland (RPEQ) with suitable erosion and sediment control experience, can prepare and certify the plan.

The practical point: the hazard rating sets the certification bar. Find out the rating before you assume who can sign.

What is an Erosion Hazard Assessment, and when do you need one?

An Erosion Hazard Assessment (EHA) classifies a site as low, medium or high risk based on factors such as the area of land disturbance, slope, proximity to waterways, and catchment size. Councils generally require an EHA to accompany applications involving soil-disturbing works. Submitting it late, or not at all, can delay your assessment. The EHA itself must be certified by someone with suitable erosion and sediment control qualifications or experience.

What is a CPESC?

CPESC stands for Certified Professional in Erosion and Sediment Control — an internationally recognised certification administered in this region by IECA Australasia. It signals demonstrated expertise in the science and practice of erosion and sediment control and is recognised across Australian government jurisdictions as an appropriate qualification for preparing and certifying ESC plans.

How does this affect your program?

If your site is high risk, a design certificate from a CPESC is typically required to be submitted to council ahead of works. Brisbane City Council, for instance, asks for the ESC design certificate at least 10 days before the pre-start meeting or the commencement of site works. Build that lead time into your program. Discovering the certification requirement the week you want to start earthworks is how projects stall.

The bottom line

Get the erosion hazard assessed early. If it comes back high risk, you need a CPESC-certified plan and enough lead time to lodge the design certificate before works begin. Requirements vary by council, so confirm the specific local rules for your site.

Frequently asked questions

Does a high-risk Queensland site need a CPESC-certified ESC plan?

Yes. On sites assessed as high erosion-hazard risk, councils such as Brisbane City Council require the erosion and sediment control plan to be certified by a Certified Professional in Erosion and Sediment Control (CPESC). Requirements vary by council, so confirm the local rules for your site.

What is an Erosion Hazard Assessment?

An assessment that classifies a site as low, medium or high erosion risk based on land disturbance area, slope, proximity to waterways and catchment size. It generally must accompany applications involving soil-disturbing works and determines the certification your ESC plan needs.
