No work on Sundays or public holidays. 4.5.1 Out of hours works While no works are anticipated to occur outside of standard hours there may be circumstances where out-of-hours activities associated with the project are necessary. Activities which may be undertaken outside of standard daytime hours (in accordance with Section 2.3 of the Interim Construction Noise guidelines (ICNG) would include the following circumstances: The delivery of materials or oversized plant as required by the Police or other authorities for safety reasons. Where it is required to avoid the loss of lives, property and / or to prevent environmental harm in an emergency. Activities which are determined to comply with the relevant Noise Management Level (NML) at the most affected sensitive receiver, excluding activities associated with the transport and handling of spoil. Such activities may include refuelling of plant and equipment maintenance. Where agreement is reached with affected receivers. Out of hours work may also be undertaken where explicitly approved through an EPL. 4.6 Plant and equipment The equipment and plant listed in Table 4-5 are likely to be used during the project.

Hornsby Quarry Road Construction Spoil Management Project 60 Roads and Maritime Services Environmental Impact Statement 4.8 Rehabilitation and final landform As identified in Table 4-1, following the completion of the project, site facilities would be demobilised and all disturbance areas would rehabilitated and stabilised to a standard as agreed to with Hornsby Shire Council. With respect to the conveyor, all equipment would be removed from site with the exception of the footings. Sealed internal access roads including Bridge Road would be retained unless otherwise agreed to with Hornsby Shire Council. Temporary project facilities would be removed from site and erosion and sediment controls would be kept in place until the site is stabilised. The quarry void would be filled to a level that would facilitate its future use for rehabilitation, this being an approximate height of RL 64, with spoil volumes of up to 1.5 million cubic metres. The filled-in void would be compacted to a level suitable for future use for recreation rather than structural/building capacity. The filled-in void would be stabilised through hydro-seeding or similar as part of site completion works. These rehabilitation measures would allow the handover of the site back to Hornsby Shire Council in an appropriately stabilised state to enable the site to be managed by Hornsby Shire Council in the interim period before its eventual rehabilitation into recreation land use. Following handover of the site, any ongoing works including works associated with the maintenance of the site would be the responsibility of Hornsby Shire Council unless otherwise agreed between Roads and Maritime and Hornsby Shire Council prior to the commencement of the works. Following site completion works, the site would revert back to the responsibility of Hornsby Shire Council. It is anticipated that existing monitoring bores on site would continue to be monitored by Hornsby Shire Council post-completion as part of the ongoing maintenance of the site (unless otherwise agreed to between parties) to monitor the stabilisation of groundwater levels post-filling. Dewatering of the quarry void would be undertaken on an as-required basis post-completion (informed by groundwater monitoring results) in accordance with the conditions of Hornsby Shire Council's existing groundwater licence, until groundwater drawdown levels into the quarry stabilise. The eventual rehabilitation of the site to recreational land use is not part of the current project. After completion of the Hornsby Quarry Road Construction Spoil Management Project, the final land form and land use for the site would be determined by Hornsby Shire Council and implemented as part of long-term plans for the site by Hornsby Shire Council, which would be the subject of a separate planning approval.
