The Environmental Assessment and Approvals Branch provides 'one-window' service for regulatory environmental approvals in Ontario . The branch administers Ontario 's Environmental Assessment Act, which applies to the planning of public sector projects and certain types of private sector projects. The Minister of the Environment is required to make decisions on the following types of submissions: individual environmental assessments, class environmental assessments, requests for exemption and review of each of the above submissions to inform and advise decision-makers, proponents (those proposing an undertaking) and the public, as necessary. The branch also reviews and approves technical applications under the Ontario Water Resources Act and Environmental Protection Act for new or modified waste, wastewater and sewage facilities, or facilities which may emit a contaminant, including noise, to the air; monitors, through an audit and acknowledgement process, compliance with soil and groundwater remediation requirements under the Brownfields Act; and administers the Pesticides Act, including licensing requirements for the sale, use and application of pesticides. Within the branch, dedicated staff are available to answer all enquiries regarding its programs from the public and the regulated community. Information and technical guidance on the requirements for specific applications are also available.
