It is 1. INTRODUCTION incumbent on the owner to keep the work in compliance with the approved plans and conditions at all times. By regulation, Climatic and physical characteristics along the eastern coast of aquaculture works are authorized for a given period of time. New Brunswick pose challenges for oyster aquaculture during the Because these works require authorization under NWPA, the winter months. Certain locations are too shallow to protect the Canadian Environmental Assessment Act (the Act) requires that oyster stock and infrastructure from damage caused by ice. Gear NWPA authorizations included on the Law List Regulations undergo and stock can become crushed under and/or become frozen into the an environmental assessment (EA). Environmental Affairs of TC is ice and then be carried away with movement of the ice during the responsible for assessing the works under the Act and completing the spring thaw. Therefore, aquaculturists may need to move their stock EA for these works. If all significant environmental impacts to a separate, temporary over-wintering site to house gear and stock identified by the assessment can be successfully mitigated, then TC during the winter months to prevent heavy losses. Thirty percent of can proceed with the process for evaluating NWPA authorization. oyster aquaculture applications received by the provincial Currently, each application for works placed on an over-wintering Department of Agriculture and Aquaculture (DAA) during the last 12 oyster site is subject to a separate EA before determining whether months specifically detail the need for over-wintering sites. the work will be authorized under the NWPA.
