Major joint venture commits to improved environmental outcomes

Downer EDI Works Pty Ltd and Seymour Whyte Constructions Pty Ltd trading as Downer Seymour Whyte Joint Venture (DSWJV) have entered into an Enforceable Undertaking with the NSW Environment Protection Authority (EPA) to improve environmental performance following uncontrolled stormwater discharges from a construction site causing water pollution.

DSWJV are constructing a major roadworks project near Nowra. In August and September 2019, there were three uncontrolled stormwater discharges from the roadwork construction site which polluted a nearby waterway and which had the potential to cause harm to the environment. These incidents were identified and self-reported to the EPA by the DSWJV.

EPA Director Regulatory Operations Cate Woods said the Enforceable Undertaking commits the DSWJV to improved staff training and increasing the frequency of environmental audits of their worksites.

“The Enforceable Undertaking also sees the DSWJV investing in environmental restoration of the local environment by supporting land care and Shoalhaven City Council,” Ms Woods said.

The EPA believes the Enforceable Undertaking will help improve environmental outcomes at other DSWJV projects across NSW.

“When sediments such as sand or soil and other building materials are washed down stormwater drains and into our waterways, it not only degrades water quality but can destroy aquatic habitats by smothering native plants and animals,” Ms Woods said.

“Whether you’re a home renovator or a major developer, it’s important that you prevent runoff from leaving your site.”

Along with the Enforceable Undertaking, DSWJV have agreed to pay the EPA $9,500 for associated investigation and legal costs.

Enforceable Undertakings are one of a number of tools the EPA can use to achieve environmental compliance. Through an Enforceable Undertaking, the EPA may secure outcomes such as environmental restoration measures or contributions to environmental projects. The undertaking is enforceable by the Land and Environment Court.
