This data represents the Environmental Protection Authority of Western Australia - Peel Harvey EPP Environmental Protection (Peel Inlet - Harvey Estuary) Policy 1992. This policy protects the estuary by setting environmental quality objectives and outlines the means by which they are to be achieved and maintained to prevent further degradation. These boundaries were gazetted and enacted with the policy on the 11 Dec 1992. Boundary was developed by the Policy Branch of the Department of Environmental Protection, a full description of the Policy and boundary is available on the EPA website www.epa.wa.gov.au.

This data represents the Environmental Protection Authority of Western Australia. This dataset represents the spatial boundaries of the SEP Cockburn Protection Levels. The dataset was updated in 2010 to accurately represent the coastline and the recent approval of James Point Stage1. When this dataset was created schedules 1-3 of the policy were updated. There are three levels of ecological protection high, moderate and low and the policy states that the percentage of Moderate protection which is Low ecological protection should not exceed 5%. This spatial data is representative of the Office of the EPA’s most recent recalculations of this statistic. Currently the percentage of MEPA which is LEPA is 4.39%. © Government of Western Australia 2014. Environmental Protection Authority. This dataset was formerly known as State Environment Policy Cockburn Protection Levels 2010 (EPA-009).

This data represents the Environmental Protection Authority of Western Australia - Environmental Protection (Western Swamp Tortoise Habitat) Policy 2011. This policy protects the habitat of the Western Swamp Tortoise by declaring beneficial uses that are to be protected and aims to ensure management activities within the policy area do not adversely impact on the habitat or these beneficial uses. These boundaries were gazetted and enacted with the original policy on the 14 Feb 2012.

This data represents the Environmental Protection Authority of Western Australia. The Kalgoorlie Environmental Protection Policy Areas are four areas in the Kalgoorlie region that are covered by the Kalgoorlie Environmental Protection Policy (Goldfields Residential Areas)(Sulfur Dioxide) Policy. The policy covers four areas; Kalgoorlie, Kambalda, Coolgardie-Boulder and the Kurrawang Aboriginal Reserve. The Purpose of the policy is to specify the maximum sulfur dioxide concentration permitted in the ambient air of a protected area. The environmental quality objectives are to control and progressively reduce sulfur dioxide concentration in the ambient air of a protected area during each year until 2008 and, to ensure that during and after 2008, the sulfur dioxide concentration in the ambient air of a protected area does not exceed 0.25ppm. © Government of Western Australia 2014.

Surface Water areas stored in WRIMS (Water Resource Information Management System). For the purposes of Surface Water resource management, the state of Western Australia is divided into Surface Water areas. The extraction and licensing of surface water resources are managed within surface water areas in order to ensure environmental requirements are met and to prevent over extraction of the resource. Surface Water Management Areas for Western Australia were derived in consultation with the regional offices, geometry is based on hydrographic subcatchments. Regional Department of Water and Environmental Regulation officers identified areas of similar management requirements to define boundaries. Management areas will be used for licencing and administrative purposes.
