Huon Valley Council - Lords Quarry Upgrade, Upper Woodstock Supplement to Environmental Effects Report dated 11 January 2018 as required by Environment Protection Authority under EMPCA Section 27E Lords Quarry – Environmental Effects Report – Supplement Version Date Recipient Organisation Revision 1 19 April 2018 Environment Protection Authority Table 1 – Additional information required by the EPA Board Issue Further information requested Response Noise Model noise impacts by quarry The Noise Study (Noise Vibration Consulting (a), December 2017) has been expanded and replaced with (Noise operations when extraction Vibration Consulting (b), March 2018). The new study takes into account noise from trucks using the access road from progresses to the upper bench the boundary of the Huon Valley Council owned land to the quarry. The upgraded study also includes an assessment as predicted by future mining of the likely noise impact of operating the crusher on the highest bench formed as a possible future expansion of the plan quarry. The results of the new study show those residences located close to the quarry (within 1 000 metres) will receive a maximum predicted noise level using the current layout (including truck on the access road) of 40 dBA and a maximum predicted noise level from the proposed expanded quarry layout of 40 dBA at a different site. The Quarry Code of Practice (Environment Protection Authority, May 2017) sets a maximum noise level recorded at a sensitive use (dwelling) during daytime hours (7.00 am to 7.00 pm) as 45 dBA. The predicted noise levels are at least 5 dBA below this level and hence should not cause a nuisance to neighbouring properties.

Lords Quarry – Environmental Effects Report - Supplement Revision 1 Table 2 – Other matters raised during public consultation period Issue Further information requested Response Justification More information justifying In order to provide the highest quality and most cost efficient construction and maintenance of council owned the development of Lords public infrastructure the Huon Valley Council (HVC) own and operate gravel pits located strategically within the Quarry in preference to other municipality. HVC recently embarked on a campaign to rationalise the council owned quarries to keep ongoing HVC assets. maintenance and permit fees to a minimum. More was invested in fewer assets ensuring that high quality product was available at the lowest possible cost from quarry assets that were well operated with minimal environmental impact. The council is able to provide better construction and maintenance to council assets at a much lower cost than by purchasing quarry products on the open market, thus stretching the rate revenue further. HVC municipal area is large extending from Vince’s Saddle to Cockle Creek and is serviced by an expansive sealed and unsealed road network. Two quarries were identified with the correct source rock to produce the products required for construction and maintenance to best service the road network The two quarries are Lords Quarry in the north and Tylers Quarry in the south. HVC previously had twelve quarries in various locations used infrequently or not at all. These quarries all required maintenance and incurred annual fees for permits and leases. Ten of the twelve leases have now been surrendered or lapsed saving the council is ongoing annual fees, cost and effort to maintain redundant sites.

Trucks dust emanating from quarry traffic travelling to and from the quarry will most likely be travelling slower than light vehicles but are still likely to on Pelverata Road will be generate dust at times. managed. Trucks servicing the quarry will be well maintained and fully serviced, operated by reputable contracting companies and will have proprietary silencers fitted. Transport Describe transport routes on A formal Traffic Impact Assessment is being prepared but does not form part of this submission. routes and public roads, residential The Pelverata area represents less than 5% of the road maintenance task hence traffic from the quarry east impact on setback and vehicle bound will be negligible. The transport route west bound on Pelverata Road is considered. Pelverata movements on the route Road Eight residences are situated close to Pelverata Road on the west bound section between Lords Quarry entrance and Channel Highway. These residences vary in distance from the road from around 89 metres to 15 metres. Traffic on Pelverata Road will increase from a weekly average of 193 vehicles to 248 vehicles with the quarry operating normally and 353 vehicles for short period when the quarry is operating at peak production.

They are seeking to upgrade the maximum permitted production, and thus the EPA requires a noise assessment to form part of the Environmental Effects Report (EER) for the proposal. This letter presents the results of this assessment, conducted by NVC in December 2017. This revision (5636_02) includes additional noise sources and assessment of potential future quarry expansions, as requested by the EPA in Table 1 of their RFI document, dated 21 February 2018. 1.0 SITE DESCRIPTION 1.1 QUARRY SITE OPERATIONS The quarry is located just south of Pelverata Road in a Rural Resource zone, and operates from 7:00AM to 7:00PM Monday to Friday, and 8:00AM to 4:00PM Saturdays. The quarry’s current permit allows a processing volume of 5,000 m3 per annum, which is proposed to be increased to 20,000 m3 p.a. under the new permit.

Much of this product will be used without further processing, with the remainder to be processed on a campaign basis. A crushing contractor is to be employed over a three to five week period per year, to process the product via crushing and screening. The remainder of the year the operations will comprise only extracting raw product and loading from the various stockpiles for transport off site. For processing the quarry is expecting to use a primary jaw crusher, a secondary cone crusher, a mechanical screen, a loader and an excavator, with potential intermittent use of a vertical shaft impactor. When crushing is not occurring, the equipment will comprise of just an excavator and a loader. The operation is currently focused on the southern half of the quarry. The pit floor is beneath the natural ground level on the west, south and east sides of the quarry, which offers topographical screening to the residences. The quarry has also proposed a future expansion, involving new benching extending south from the existing pit. The first of these benches is to be at RL202, and day-lighting on the north-east and south- west edges of the ridge. Further benches will reduce the level to equal the existing quarry pit level. It is proposed that the crusher may sit on top of the new bench at some points, to expedite processing. 1.2 SURROUNDING AREA The immediate surrounds of the quarry are bush, and zoned as Rural Resource.
