Sewers By-law
Sewers By-law sets limits on heavy metals, biochemical oxygen demand (BOD), total phosphorus, total suspended solids (TSS), total kjeldahl nitrogen (TKN), oil & grease and toxic organic compounds in wastewater discharge to sanitary and storm sewers.
Municipal Code Chapter 681 Sewers enacted in 2000
Protect aquatic environment
Ensure the health & safety of City staff & public
Protect sewer infrastructure from obstruction and deterioration due to harmful discharges
To meet legislative & regulatory requirements
To control biosolids quality
Protect wastewater treatment plant operations

Sewage Biosolids
•
2002: Biosolids incineration ceased at the Ashbridges Bay Wastewater Treatment Plant.
•
2009: City Council adopted the Biosolids Master Plan for the City’s WWTPs with “Beneficial Use Option” as primary biosolids management strategy.
•
Biosolids for land application provide an economic benefit in addition to their environmental advantages.
–
Nutrient and soil conditioning benefits to farms
–
Reuse of key resources such as Phosphorous & Nitrogen
–
Costs $250/tonne to incinerate compared to $85/tonne to recycle biosolids

10. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
MOE regulations on biosolids for land application
All municipalities must meet the requirements for land application of biosolids under the Nutrient Management Act (NMA). Based on these biosolids quality requirements,
•
Sewer Bylaw created a list of Subject Sectors & 38 Subject Pollutants and newly added Hexavalent Chromium
•
Heavy Metal Subject Pollutants match those of the biosolids regulated by MOE
11 Regulated Metals Under NMA (2002)
Arsenic
Mercury
Cadmium
Molybdenum
Cobalt
Nickel
Chromium
Lead
Copper
Selenium
Zinc

Pollution Prevention (P2) Program
•
Pollution Prevention (P2) Program introduced through the Sewers By-law in July 2000
–
first municipality in Canada to include mandatory reporting of P2 planning in Bylaw
–
P2 Plan submissions every six years with P2 Update submissions in the second and fourth year on 38 subject pollutants present in effluent discharged from property
•
Best Management Practices (BMP) was introduced to certain commercial sectors due to lack of technical expertise, similar operating practices and equipment set up and use of similar products in those sectors
–
automotive repair, vehicle wash and fueling stations (2005)
–
photo finishing (2007)
–
BMP focuses on operations to minimize pollutants rather than products, which they have no control over

12. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
P2 Program Successes (Appendix B of PW27.8 Staff Report)
•
Metal concentration decline in wastewater with 5 of the 11 tested heavy metals showing an appreciable downward trend
–
average results of the remaining 6 heavy metals were below the by-law limits
•
Declining concentration of pollutants in industrial wastewater, including industrial facilities, metal finishers and hospitals
•
Manufacturers reformulated products to eliminate or reduce subject pollutants so that Toronto customers could comply with P2
–
many facilities became exempt from P2 Planning by eliminating the use of subject pollutants
•
Amalgam separators installed for all affected dental offices
–
drop in mercury concentration in wastewater treatment plants’ influent and sludge in 2002 with continual decline
–
40-70% reduction of mercury in the biosolids during initial P2 Program years

P2 Program Recent Changes
In December 2013, City Council adopted the ‘Sewers By-law Pollution
Prevention Program (P2) and Hexavalent Chromium Stakeholder Update
Report’ PW27.8:
•
Instead of P2 Update submissions in the second and fourth year after a P2 Plan is initially submitted; only one P2 Update is required by the end of the third year after an initial P2 Plan submission
–
more in line with three and six year targets of P2 Plan
–
came into effect January 1, 2014
•
Hexavalent Chromium has been added as the 39th subject pollutant
–
every industry which discharges Hexavalent Chromium has until Dec. 31, 2014 to amend its latest plan to include hexavalent chromium and must thereafter include it in all plans until no longer discharged

17. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
P2 Program Proposed Changes
In December 2013, City Council directed City staff to undertake
consultations in 2014 regarding the proposed changes to the Pollution
Prevention (P2) Program and subsequent Sewers By-law, Municipal
Code Chapter 681. These changes include:
•changes to the dental office submission requirement;
•changes to the grease interceptor requirement;
•creation of a Best Management Practice (BMP) for the automotive refinishing sector;
•creation of a Best Management Practice (BMP) for mobile washing business operations; and
•creation of a subject pollutant threshold reporting list.

18. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
Dental Office Submission Requirement
Currently dental owners:
–
submit a P2 Plan every six years
–
submit a P2 Update to the City by the end of the third year from the date of the initial P2 Plan submission
–
install and properly maintain dental amalgam separator(s)
Proposed Changes:
–
dental owners will be required to submit a P2 Plan only ONCE followed by annual submission of proof of maintenance of the amalgam separator
Benefits:
–reduced P2 Plan submissions, thereby reducing administration on the part of the dentist and City staff resources
–ensure amalgam separators are properly maintained, thereby reducing levels of mercury entering the sewer

19. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
Grease Interceptors
Currently restaurants/food premise owners:
–
shall take all necessary measures to ensure that oil and grease are prevented from entering the sewer (vague for enforcement)
–
shall install and properly maintain a grease interceptor
Proposed Changes:
–
restaurant/food premise owners will be required to follow a Code of Practice based on the CSA Standard B481 Series-12 Grease Interceptors, which includes maintenance, size, location and other preventative measures identified by the City
Benefits:
–ensure grease interceptors are properly installed/maintained to reduce oil & grease entering the sewer; protect public health & environment
–reduced sewer back-ups and water infrastructure remediation

20. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
BMP for Automotive Refinishing Sector
Currently automotive refinishing businesses:
–
submit a P2 Plan every six years
–
submit a P2 Update to the City by the end of the third year from the date of the P2 Plan submission
Proposed Changes:
–
automotive refinishing businesses will be required to comply with the newly created Best Management Practices (BMP)
–
submit a declaration form confirming compliance with BMP
Benefits:
–reduced P2 Plan submissions, thereby using City staff resources efficiently & meaningfully and reducing administration for the sector
–ensure compliance with BMP to keep pollutants from being discharged into the sewer, thereby protecting water quality
–promote good housekeeping techniques & P2 practices

21. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
BMP for Mobile Washing Business Operations
Currently mobile washing business operations:
–
have no specific requirements other than to comply with the Sewers Bylaw
Proposed Changes:
–
mobile washing business operations will be required to comply with a newly created Best Management Practices (BMP)
–submit a declaration form confirming compliance with BMP
Benefits:
–ensure compliance with BMP to keep pollutants from being discharged into the storm sewer, thereby protecting water quality and the environment

22. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
Subject Pollutant Threshold Reporting List
Currently industrial, commercial and institutional facilities:
–
are required to submit a detailed six-year plan to the City that identifies operations or activities of an owner or operator of commercial, institutional or industrial premises identifying specific pollution prevention methods (under § 681-5)
–
must identify pollution prevention methods, which may include product substitution, product reduction, operational modifications, equipment upgrade or wastewater treatment
–
are required to submit a P2 Update to the City by the end of the third year from the date that a P2 Plan was required to be submitted
–
must include in the P2 Plan and P2 Update any amount of a subject pollutant present in the effluent discharged from a property
NEW 2014

23. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
Subject Pollutant Threshold Reporting List
Proposed Change:
–
creating a subject pollutant threshold reporting list, which would include the minimum level of a subject pollutant that requires a P2 Plan and subsequent P2 Update submission
P2 Program Goals:
–
minimize subject pollutants from entering the sewer
–
make industry aware of their operations through the reporting process and identify methods to reduce/eliminate subject pollutants
A subject pollutant threshold reporting list will not affect P2 Program
goals as it will only eliminate the reporting of trace amounts
•
E.g.. Total Chromium of 0.004 mg/L found naturally when washing broccoli at a food premise

24. D E D IC A TE D T O PROVIDING SERVICE EXCELLENCE: QUALITY DRINKING WATER - WASTEWATER TREATMENT - STORMWATER MANAGEMENT
Threshold Reporting List Benefits
By creating a subject pollutant threshold reporting list:
–
the City can eliminate the requirement of industries to report trace amounts of subject pollutants discharged, thereby allocating its resources on more problematic subject pollutants, industries, sectors etc…
–
some industries that are required to prepare a P2 Plan may not have to submit a P2 Plan for the subject pollutants that are below the proposed thresholds ,thereby allocating their resources on problematic subject pollutants present in the effluent discharged from their property
–
in line with ChemTRAC and MPRI threshold approaches
Note: these threshold changes will not impact those sectors that are on a
Best Management Practice (BMP), such as dental offices and dry cleaners.
