 Posted: Tue Jul 14, 2009 1:39 pm Post subject: Supplementary EIS - Preliminary works phase - where's the $ |
 |
|
Here is what is being proposed immediately after state and federal approval - Premier Bligh's delay in construction appears to be yet another deception.. the Preliminary Works phase includes excavation of approximately 700,000m3 of material will be excavated from the dam wall alignment to a depth of 15m below the ground level to the water table. Here are some more details..Where is the money for this coming from?? Doesn't appear to be in the 09/10 Budget or is it in the $75M earmarked for mitigation measures???
From Chapter 2 of the Supplementary EIS..
| Quote: | 2.1.1 Preliminary Site Works Page 2-5
This section describes the preliminary site works which are required for mobilisation to site and facilitate the timely construction of the Project. These activities are proposed to commence immediately after State and Commonwealth approval of the EIS, in preparation for the main construction phase of the project. It is important to note that some of the proposed activities (such as vegetation clearing) may require separate State approval. These approvals will be obtained prior to commencement of the preliminary activities. Furthermore, an overall Preliminary Site Works Environmental Management Plans (PEMP) will be prepared and implemented for this stage of the works. This plan will build on the measures identified in the EMP located in Chapter 30 of the Supplementary Report, and will provide detailed management measures for each of the activities described below.
The purpose for identifying preliminary site works is to provide guidance to conditioning of the project approval to allow for necessary preparation works to commence as soon as possible (after necessary approvals in accordance with appropriate additional approvals and management plans) whilst the main construction activities remain subject to conditions which may involve a longer timeframe to address.
For the purposes of this report, the preliminary site works are described in relation to the location of the activities.
General Works – Project Area
Conduct investigations of potentially contaminated sites, and commence remediation if required.
Dam Construction Footprint
The construction footprint includes the area as identified on Figures 2-3 and Figure 2-4. The following activities are proposed:
•establishment of access roads to allow access to proposed dam site;
•establishment of site offices (demountable/ relocatable buildings, no accommodation), including associated stormwater and drainage controls;
•conduct geotechnical investigations for the following:
•geotechnical drilling in the Mary River at the proposed dam wall alignment, utilising a drill rig from a free floating pontoon or similar; and
•geotechnical drilling and trial blasting on the right abutment to determine the suitability of the material for construction purposes (note that this activity constitutes an ERA, and is further described in Section 7.5 of this report.
•vegetation clearing in the dam construction area on both the left and right abutments.
•commencement of excavation of alluvium along the proposed dam wall alignment. The extent of the excavation is shown on Figure 2-3. The proposed excavation will be to a depth of approximately 15 m below ground level, to the water table. The excavation will cease at this point, and it is anticipated that approximately 700,000m3 of material will be excavated during the Preliminary Works phase. The material will be used for a range of purposes including preparation of site areas (pad/ foundation preparation), including site offices, lay-down and storage areas; and construction of haul roads;
•commence excavation of spillway channel on right embankment; and
•conduct sampling up and downstream of the proposed dam wall location to obtain samples of gravel and sand to determine suitability as construction materials. The sampling will be proposed by using an excavator from the river bank. The volume of material proposed to be extracted will be less than 200m3, therefore will not trigger ERA 19 – Dredging. However, all other approvals will be obtained prior to the commencement of this activity.
Roads
•Vegetation clearing and commencement of bulk earthworks for the following roads;
•Dam Access Road;
•Gympie-Brooloo Road;
•Meddleton Road and interchange;
•Mary-Valley Road; and
•Hasthorpe-Goomong Road.
Supporting Infrastructure
•Freshwater Species Conservation Centre (Stage 1) - vegetation clearing, bulk earthworks and connection to services;
•site selection for the proposed construction camp. Once the site has been identified, it is proposed to commence vegetation clearing, bulk earthworks connection to infrastructure services;
•commencement of the relocation of utility relocation, including Energex and Telstra; and
•commencement of the relocation of the Energex substation, which will include vegetation clearing bulk earthworks |
