Description of proposal

53.22 Proposal to expand the Colac Quarry operation into the new NDA Site. The operation will seek to use as much existing infrastructure as possible to minimise the development footprint and no fixed buildings will be erected on the NDA Site. The planning application relates to a new parcel of land, known as the proposed Northern Development Area (NDA) at 170 Ondit- Warrion Road, Ondit in Victoria. The new parcel of land is adjacent to Holcim’s existing Colac quarry operation located at 75 Potters Road, Ondit (WA158). Statutory Endorsement of Work Plan PLN-001672 for the NDA was received from the Earth Resources Regulation branch of the Department of Energy, Environment and Climate Action on 19th of February 2024. This new parcel of land known as the NDA and will operate concurrently with the existing operations under existing Work Authority (WA158). The overall quarry capacity (considering both the existing quarry and proposed NDA) will not change, producing approximately 300,000 tonnes of product per annum averaging about 1,000 tonnes per day however on exceptional days production may reach up to 3,000 tonnes. Following stripping of the topsoil and overburden, primary basalt extraction within the NDA will occur via drill, and blast, secondary breaking will be undertaken where required, via hydraulic rock breaker. Extraction of the blasted basalt material will be undertaken using an excavator, dump trucks and loaders. Extracted Primary Raw Feed from the NDA will be crushed using a mobile/modular primary and secondary crushing plant located within the NDA. Crushed stone will then be transported to the existing tertiary and screening plant located at 75 Potters Road Ondit (WA158) and processed to meet the required product specifications before being transported offsite in road trucks for customers.
