The project involves carrying out emergency restoration work on abutment 2 on the left side of the Fitzroy River Bridge (B1311), Fitzroy Crossing. Clearing of native vegetation is the main environmental impact of the project, with approximately 1ha to be cleared next to the Fitzroy Bridge. This clearing will provide a lay down and turn point area where machines can access the guideway.
Clearing activities are deemed not to be inconsistent with any of the 10 clearing principles. Main Roads applied to the Department of Water for a permit to interfere with bed and banks and a 5C license to take surface water.

A search of DEC's Contaminated Sites Database was conducted. https://secure.dec.wa.gov.au/idelve/css/) to determine if the project site contains or is adjacent to any contaminated sites, refer to Appendix H. No further investigation is required as the site is outside the site high risk for ASS and no irrigation or excavation below the planned water table. The need for a local air quality assessment was determined using the criteria outlined in the MRWA Environmental Guide, Air Quality.

ASSESSMENT Only approximately 1 ha is proposed to be cleared with adjacent vegetation remaining, this will not cause significant land degradation. Native vegetation should not be cleared if the clearing of the vegetation is likely to have an impact on the environmental values of any adjacent or nearby conservation area. The proposal does not conflict with this Principle as remaining native vegetation in the project area is not associated with any adjacent or nearby conservation areas.
Potential clearing of remaining native vegetation is considered unlikely to cause deterioration of surface or groundwater quality. ASSESSMENT The proposed improvement should aim to minimize changes in natural flows and reduce the impact of flooding and channel erosion.
S UMMARY OF M ANAGEMENT A CTIONS
Whether the assessment indicates that clearing is inconsistent with one or more clearing principles. Whether the assessment indicates that the cleanup is contrary to the cleanup principle of (g) soil degradation, (i) surface or groundwater quality, or (j) flood frequency. Whether the project will involve cleaning for purposes deemed to be of a temporary nature in accordance with condition 13 of CPS818.
ASSESSMENT OF ASPECTS AND IMPACTS
A search of the databases of the Australian Heritage Places Inventory and the Heritage Council of Western Australia has revealed that there are no heritage sites in the proposed work areas. Wetlands DEC shapefiles show that there are no wetlands in the vicinity of the project area. A search of the DoW database has confirmed that the proposed works will not disrupt or interrupt natural drainage and runoff patterns.
A search of DEC's contaminated sites database indicates that there are no identified contaminated sites within the project area. National Heritage Sites A search of the Australian Heritage Sites Inventory database has shown that there are no listed significant heritage sites present in the proposed works areas. A search by the Department of Sustainability, Environment, Water, Population and Protected Communities' Research Tool found no Ramsar wetlands in the vicinity of the project.
An investigation by the Department of Sustainability, Environment, Water, Population and Protected Affairs found no threatened ecological communities, 4 threatened species and 9 listed marine species in the vicinity of the project in the search tool. A search using the search tool of the Ministry of Sustainability, Environment, Water, Population and Protected Affairs found 12 migratory species in the vicinity of the project.

The purpose of this EIA is to minimize the environmental impacts associated with the proposed works, as well as to identify areas of responsibilities necessary for the implementation of management strategies. The project management measures identified within this EMP are in addition to the standard environmental management contract specifications used for Category 2 projects. Main Roads' standard environmental contract specifications (Specifications and 304) must be complied with where appropriate.
After project completion and project handover, the asset manager must develop a monitoring program to monitor those aspects identified as requiring monitoring. Due to the scale and nature of the project, no contingency measures have been defined as the inherent environmental risks are low. Due to the scale and nature of the project, there is no need to audit the implementation of the EMP, as the environmental risks are low.
All projects must maintain the required records relating to the clearing of native vegetation under the target permit. Replanting will take place along Great Eastern Highway unrelated to this project, but topsoil and mulch from this clearing will be used in this replanting. Vegetation clearance Ensure that the overall objectives of the alignment and construction works are compatible with the maintenance and, where possible, the enhancement of the biological integrity of the surrounding environment and the reduction of vegetation loss and.
Project Manager Major road construction works will be undertaken in the summer to reduce potential. This vegetation will be mulched and used for the rehabilitation works of the Great Eastern Freeway 2011. Surface drainage Maintain the hydrological regime existing prior to the construction of the proposal.
Public pedestrian access must be planned and implemented prior to the construction of the works. Main roads contractor Any complaints about dust will be resolved as soon as possible.
