The Environmental Protection Authority (EPA) has prepared a Technical Report 'Carnaby’s Cockatoo in Environmental Impact Assessment in the Perth and Peel Region', under Section 16(j) of the Environmental Protection Act 1986.

The Perth and Peel regions are experiencing rapid growth and the population is forecast to reach 3.5 million by 2050. The EPA is concerned about the cumulative impacts of a growing city, against a backdrop of historical clearing, on Carnaby’s cockatoo.

The EPA has established an environmental quality management framework for Cockburn Sound, which has been given effect through the State Environmental (Cockburn Sound) Policy 2015 (Government of Western Australia, 2015). The framework is underpinned by established environmental values and clearly expressed and spatially defined environmental quality objectives to guide decision-making and provide the common goals for management.

Several water quality surveys were undertaken in the coastal waters of the Kimberley region from September 2007 to August 2008 to measure typical TSS concentrations and determine background total and dissolved concentrations of aluminium, arsenic, cadmium, chromium, cobalt, copper, lead, mercury, nickel, silver and zinc. This work was undertaken to establish a baseline for the Kimberley from which to assess local and regional changes in water quality in years to come and to ascertain whether the guideline trigger values from ANZECC & ARMCANZ (2000) are relevant to the region.

A water quality survey was undertaken in December 2008 at two locations on the Western Australian Kimberley coast that were shortlisted as potential sites for the construction of an LNG processing precinct. Water samples were collected and processed to determine total suspended solids (TSS), chlorophyll a, b and c, ammonia, total phosphorous (P), total nitrogen (N), nitrate plus nitrite (NO3+NO2) and orthophosphate concentrations at selected sites across both study areas.
