Page 2 – May 1, 2015 Presentation Outline Introduction Application Types of wastewater systems Part 1: Authorization to Deposit – Deleterious substances and authorization to deposit – Monitoring requirements – Record keeping – Reports (identification, monitoring, overflow) Part 2: Transitional and Temporary Authorizations to Deposit – Transitional authorization – Temporary authorization to deposit un-ionized ammonia – Temporary bypass authorization – Exception to chlorine requirements Coming into Force Administration
Page 3 – May 1, 2015 Introduction Wastewater Systems Effluent Regulations (WSER) were published in Canada Gazette, Part II on July 18, 2012 The purpose of this presentation is to provide a brief overview of the WSER with a focus on upcoming requirements. This document is intended to provide guidance only by reviewing some of the provisions of the Wastewater Systems Effluent Regulations. This document is not a substitute for reading the WSER and does not in any way supersede or modify the Fisheries Act or the WSER. In the event of an inconsistency between this document and the Act and/or the WSER, the Act and the WSER prevail. Individuals with specific legal problems are urged to seek advice from legal counsel.
