Area proposed to be cleared: 1.3 hectares (ha). Project purpose / components: This project involves the widening of SCH to create a 5 m construction zone and to upgrade culverts within this SLK range. Temporary clearing required: None. A detailed Assessment Report (AR) of the project clearing activities was undertaken. The AR outlined the key activities associated with the road project, the existing environment and an assessment of native vegetation clearing. This assessment provided an evaluation of the vegetation clearing impacts associated with the project using the ten Clearing Principles and strategies used to manage vegetation clearing. Key items associated with the clearing assessment are listed below. KEY CLEARING IMPACT ASSESSMENT ASPECTS This project is o May be at variance to Principle (a) o May be at variance to Principle (b) due to the removal of 1.12 ha of foraging habitat and 9 potential breeding trees Black Cockatoo habitat o At variance to Principle (d) due to the removal of 0.2 ha of the EPBC Kwongkan community TEC. o At variance to Principle (f) due to the removal of 0.12ha of mapped riparian vegetation o May be at variance to Principle (h) due to the adjacent Bakers Junction Nature Reserve o Not likely at variance to the remaining Principles This project involves the removal of 1.3 ha of native vegetation A biological survey and dieback survey were completed for this project. The submission period for this project is still open and this document will be updated once this period has closed. Given the small, linear nature of the clearing and the good condition of the surrounding reserves an exemption request from completing an Offset will be sent to DER for approval. The Assessment Report identified several environmental constraints associated with the proposed project activities. Further environmental approvals, permits or licences are needed for implementation of the project. KEY VEGETATON MANAGEMENT ACTIONS Project specific environmental management actions have been developed to manage all clearing impacts and these are outlined in the Vegetation Management Plan (VMP) provided in Appendix D. Where possible the clearing will be limited An Environment Officer will remain on site when clearing activities are undertaken. All important habitat trees will be demarcated to remain. Any damage beyond the extent of the approvals will be rehabilitated. Project area will be included in Main Roads annual weed program to ensure no new weed infestations particularly adjacent to the Nature Reserve. Possum Management Plan will be implemented MAIN ROADS Western Australia 4 of 35 SCH Widening 8.2-14.16 SLK-Assessment Report &VMP 13 June 2017 Dieback Management Plan will be implemented. Main Roads State-wide Purpose Clearing Permit CPS 818 will be used to undertake native vegetation clearing for the project. Project clearing will be undertaken in accordance with the conditions of CPS 818 and detailed records of native vegetation clearing will be maintained as required under the permit.

ASSESSMENT SCOPE This environmental impact assessment involved a desktop analysis of environmental aspects and impacts, a site investigation, and an assessment of native vegetation clearing impacts. The study area is confined to a local area of a 10 km radius. This assessment determined the need to develop and obtain approvals from the Department of Environment Regulation (DER) for revegetation plans, vegetation management plans, dieback management plans or offset proposals. 2. PROJECT DESCRIPTION This project occurs on SCH between 8.2-8.94 and 9.78-14.16 SLK in the City of Albany. It is anticipated works will consist of limited vegetation pruning works to create a 5m construction zone at certain location on each side of the road to allow for Shoulder Widening and Sealing works ideally retaining the existing batters. It is anticipated therefore the works in this instance will consist primarily of limited pruning works. Culvert extension works will be undertaken on unknown number of culverts to be determined once survey is complete from SLK 8.2 to SLK 14.16. Vegetation to be removed (pruned) to create a vegetation free zone 5m from concrete structures as per “Operational Guidelines 94” (Item 3.6 Drainage) and is also covered under RMIP “Vegetation Affecting Road Pavement”. 2.1 Project Location The project area is located on SCH 8.2-14.16 SLK within the City of Albany.

METHODOLOGY 3.1 Preliminary Desktop Study An initial preliminary desktop assessment was undertaken to assess the proposed native vegetation clearing and potential constraints associated with the project. The desktop assessment included viewing GIS shapefiles, reviewing government agency managed databases (where necessary) and consulting with relevant stakeholders. The outcome of the desktop study, identified that native vegetation clearing was at variance with one or more of the clearing principles. 3.2 Detailed Clearing Impact Assessment Further environmental assessment of the impacts of native vegetation clearing was undertaken and an Assessment
