ENVIRONMENTAL PROTECTION NOTICE
Giscome Quarry and Lime Plant Project Public Comment Period
Graymont Western Canada Inc.
of #200-10991 Shellbridge Way, Richmond, BC, V6X 3C6 has proposed to develop a limestone quarry and lime processing facility (the Project) near Giscome, British Columbia. An Environmental Assessment Certificate (EAC#M16-02) was issued for the project on December 14, 2016. The Project includes a limestone quarry, processing plant and an overland conveyor to convey the limestone to the plant site for processing.
The Project is located approximately 27km east-northeast of Prince George. The Project is accessible from Highway 16 and the Upper Fraser Road. The proposed quarry is located on Crown land, approximately 4km southeast of the settlement of Giscome. The proposed lime processing plant is located on Graymont-owned land, approximately 1km east northeast of the settlement of Giscome. At start-up, approximately 600,000 tonnes per year of limestone will be extracted from the quarry. At full capacity, and in the future, approximately 1.7 million tonnes per year of limestone could be extracted from the quarry.Approximately 200,000 tonnes per year of lime will be produced by one lime kiln in the initial start-up of the facility. At full capacity, approximately 600,000 tonnes per year of lime could be produced from three kilns. The Major Mines Permitting Office (MMPO) is leading a joint application review for the proposed Giscome Project on behalf of the BC Ministry of Energy and Mines and Ministry of Environment. MMPO is currently inviting public commentsregarding the proposed Giscome Project related to the following authorizations:
Authorization: Mines Act Permit Amendment; Act or Regulation: Mines Act; Project Component: Part 10.2.1 Health and Safety Reclamation Code for Mines in British Columbia; Contact: Chief Inspector of Mines, Ministry of Energy and Mines, c/o Jen Stuart, Senior Project Lead, Major Mines Permitting Office, Ministry of Energy and Mines, 2nd Floor - 4441 Columbia Street, Kamloops, BC V2C 2T3. Authorization: Environmental Management Act Permit Amendment; Act or Regulation: Environmental Management Act; Project Component: Waste Discharge; Authorization; File No.: #PA108587 and PE108588. Contact: Jen Stuart, Senior Project Lead, Major Mines Permitting Office, Ministry of Energy and Mines, 2nd Floor - 441 Columbia Street, Kamloops, BC V2C 2T3 Mines Act Permit: Graymont has submitted, as part of a joint application, a proposed mine plan together with a program for the protection and reclamation of the land related to the Project. Mining Lease Graymont Western Canada Inc., free miner certificate client number 105327, has applied to the Chief Gold Commissioner for the Province of British Columbia, for a mining leases of minerals identified by the mineral claims listed below. The mineral claims have been surveyed by Robert Yates, BCLS, whose field notes and plans have been approved by the Surveyor General. The following mineral claims are subject to the mining lease application:

Environmental Management Act Permit: Graymont has submitted an application under the Environmental Management Act to request discharges from Sedimentation Ponds 1 through 4, associated with the limestone quarry and the Plant Site Pond associated with the lime processing plant. Consistent with current practices, the water management will include conveyance, collection and treatment (in settling ponds) of contact water for the removal of total suspended solids (TSS) prior to discharge. The settling ponds will provide physical treatment to reduce TSS concentrations in the discharges to Bateman Creek. The sedimentation ponds have been designed to ensure Total Suspended Solid levels in the water discharged will not exceed approximately 15 mg/L, which is the limit specified in the Metal Mining Effluent Regulation.
Discharge from runoff water and water infiltrating through the Limestone Fines Stockpile (LFS) and Soil Stockpile will also be controlled by diversion channels and sedimentation ponds (referred to as Sedimentation Ponds 1 and 2). Sedimentation Pond 1 will collect runoff from the Soil Stockpile and the majority of the LFS. A spillway will direct discharge from Sedimentation Pond 1 into Unnamed Tributary 7.1. As an additional sedimentation measure for Unnamed Tributary 7.1, two collection ditches will be constructed to the immediate south of the soil stockpile. Sedimentation Pond 2 will collect runoff from the east portion of the LFS.
Discharge of water pumped from the limestone quarry will be controlled by diversion channels and two sedimentation ponds (referred to as Sedimentation Ponds 3 and 4. Quarry water will be pumped into Sedimentation Pond 3, which will then overflow by gravity into Sedimentation Pond 4. Overflows from Sedimentation Pond 4 will discharge through an engineered spillway. Downgradient of the spillway, the pond outflows will be conveyed in an engineered channel to Unnamed Tributary 7.2. The estimated characteristics of the water ("effluent") are as follows:
Air emission sources identified within the processing plant include point sources (generators, baghouses and kilns), volume sources (material handling sources for fuel transfers and truck traffic), and area sources (material handling sources for storage piles).
Air emission sources identified within the quarry include point sources (generators), volume sources (material handling sources - material transfers, crushing, and screening) and area sources (material handling sources - storage piles).
Baghouses will be used to control particulate matter emissions at the point sources. The characteristics of the air emissions (total emissions for all sources) are summarized below:
