  1. WASTEWATER SYSTEMS EFFLUENT REGULATIONS April 4, 2014 Chris Power, P.Eng.

  2. Wastewater Definitions Wastewateris composed of industrial, commercial, institutional and domestic wastes including blackwater & greywater. Effluent: wastewater that is deposited from a wastewater system Influent: means wastewater entering a wastewater system

  3. What is WSER? Wastewater Systems Effluent Regulations • Established (July 18, 2012) under the (Federal) Fisheries Act to regulate wastewater outflows • Sets minimum effluent quality standards achieved through secondary wastewater treatment • Defines sampling, monitoring, record keeping & reporting requirements • Will help protect rivers, lakes and oceans with a workable set of rules for Canada's approximately 4000 wastewater treatment systems.

  4. Application • Applicable to wastewater systems that collect, or are designed to collect, an average volume of 100 mᶟ/d or more of influent. • Not Applicable to - • Wastewater systems located in the far north (Nunavut, the Northwest Territories), north of 54th parallel in Newfoundland & Labrador & Quebec • Systems on the site of industrial, commercial or institutional facilities that are designed to collect less than 50% of blackwater and greywater combined. • Mills as defined in the Pulp and Paper Effluent Regulations

  5. Geographic exception in NL

  6. Wastewater in NL • Approx. 739sewer outfallsin the province of Newfoundland & Labrador • WSER applies to the outfall not the community

  7. WSER • WSER does not cover very small discharges • Existing provincial policy of no new raw water discharges will apply. 100 mᶟ/d of influent equates to • 100,000 Litres/day • Approximately 294 people or 147 homes (E.g. assuming 340 litres/person/day and 2 people/home)

  8. Determine if the outfall is 100 m3 • Communities should do a desktop assessment on all individual outfalls to determine eligibility if the outfall is 100 m3 or not (and keep documented results!!) • Communities can use their data on how many people connected to the system • If a community’s outfall is clearly over 100 m 3 then Start flow monitoring

  9. Flow Monitoring • Consider consultant to assist in flow monitoring • Smaller communities in the same geographical region may work together and hire a consultant for flow monitoring. This will be the most economical approach.

  10. Effluent Quality Standards • Wastewater discharges must meet

  11. Types of Wastewater Systems Two types (for the purpose of regulation) • Intermittent Wastewater system: Hydraulic Retention Time (HRT) of at least 90 days, four discharge periods per year • Continuous Wastewater System: Any wastewater system other than an intermittent wastewater system Newfoundland & Labrador has continuous systems for the most part according to Environment Canada

  12. Intermittent System Sampling- CBOD, SS and NH3

  13. Continuous Systems Sampling- CBOD, SS and NH3

  14. Continuous Systems with HRT ≥ days Sampling- CBOD, SS and NH3

  15. Acute Lethality Testing

  16. Sampling • There is currently no lab in the province accredited to test effluent for CBOD, SS and NH3. The nearest accredited lab is in Bedford, NS. • AGAT Labs -Mt. Pearl (709-896-0888) (samples collection depot) Labs previously used by DOEC • Maxxam Analytics Inc. • Exova Canada Inc. • Maxxam St. John’s office can coordinate with Bedford office to send samples for testing. Contact Maxxam at: (709) 754-0203 or (902) 832-4852

  17. Sampling • EC suggests that towns should request that the following be tested for: • Carbonaceous BOD (CBOD) • pH • Total Suspended Solids (TSS) • Unionized Ammonia @ 15oC (as NH3)

  18. Flow Meters and Monitoring • Flow monitoring equipment to be installed as soon as possible by owners and operators of wastewater systems (if required). Maintenance and calibration of equipment is required. • All outfalls (subject to WSER) need be monitored. A representative sample may be chosen and results applied to remaining outfalls. • For information on available flow meters, visit the following websites: • http://www.3spgroup.com/3SPG/Applications_homeES.php?locale=en&Application_no=7 • http://www.wastewatercanada.com/index.htm • http://www.environmental-expert.com/water-wastewater/sewers/products/keyword-sewer-flow-monitoring-14731/location-canada-newfoundland • http://biomaxx.ca/products.php

  19. Implementation Timelines • Wastewater systems not meeting the effluent quality standards would need to upgrade their systems to meet the standards • Data collected through the quantity and quality monitoring program is converted into a score • Score is then used to determine the level of environmental risk associated with the outfall and the timeframe required to meet the new effluent requirements. • 2020 (high risk), 2030 (medium risk) or 2040 (low risk) timeline

  20. Implementation Timelines • January 1, 2013 • Effluent quality and quantity monitoring begins. • Combined sewer overflow (CSO) recording begins. • Record keeping and reporting requirements are in force. • Records must be kept for 5 years

  21. Implementation Timelines • May 15, 2013 • Deadline to submit identification report for wastewater systems in operation on January 1, 2013. This is a one time requirement • Deadline to submit first quarterly monitoring report (If applicable)

  22. Submit ID Reports online • Access Effluent Regulatory Reporting Information System(ERRIS) via Environment Canada’s Single Window Information Manager (SWIM) EC is ready to assist municipalities to navigate SWIM & ERRIS • Create an account with SWIM • After log-in, user is linked to SWIM • Within SWIM, create your user profile • Then go ERRIS

  23. EC Single Window Information System (SWIM)

  25. ERSIS

  26. Implementation Timelines • February 14, 2014 • Deadline to submit first annual monitoring report (If applicable). • February 15, 2014 • Deadline to submit first CSO report.

  27. Implementation Timelines • June 30, 2014 • Deadline to apply for transitional authorization (TA). • TA requires a year’s worth of flow and quality data. • WW systems not meeting standards can apply • Conditions will be set under which the facility may continue to operate, as well as risk based timeline for achieving final compliance

  28. Implementation Timelines • January 1, 2015 • Effluent quality standards and limits in TAs are in force. • Exception: TRC standard for <5000 m3/day wastewater systems – Jan 1, 2021. • Application for temporary bypass authorizations may be submitted • Acute lethality monitoring begins for wastewater systems that already meet the effluent quality standards.

  29. Implementation Timelines • June 30, 2017 • Deadline to submit the progress report for wastewater systems with a TA expiry date of December 31, 2020.

  31. Funding • Funding for Flow Meters is eligible under MCW and MYCW program of MIGA. However this year’s applications are now closed. Gas Tax may be used with approval of GT Secretariat. • Monitoring Costs are not eligible. • Wastewater treatment infrastructure is an eligible category under the Provincial-Territorial Base Fund, the Green Infrastructure Fund and Gas Tax Fund. The Federal budget made a commitment to the renewal of a 10-year Building Canada Infrastructure Program which the province anticipates will cover WWT.
