Executive Summary

The purpose of this report is to provide information to the public regarding the environment footprint of Bruce Power’s A and B generating stations. The Environment Monitoring Program (EMP) report fulfills regulatory requirements on environmental protection in accordance with Licence Condition 3.3 of the Bruce A and Bruce B Power Reactor Operating Licence (PROL) Bruce Nuclear Generating Stations A and B 18:00/2020 and the CNSC Regulatory Document REGDOC‑3.1.1 Reporting Requirements for Nuclear Power Plants, Section 3.5.

Environmental protection encompasses the following specific areas – effluent and emissions control (releases), environmental management system, assessment and monitoring, protection of the public, and environmental risk assessment. As such, this report describes the effluent and environmental monitoring programs related to Bruce Power’s operations. The monitoring programs examined in the report include radiological, non-radiological and hazardous substances, and quantifies the effect on human and non‑human biota. 2016 site emissions

The radiological and non-radiological emissions from the Bruce site are well within regulatory limits and requirements. With respect to non-radiological emissions, Bruce Power is in compliance with applicable Provincial regulations, approvals, and permits. With respect to radiological airborne emissions and liquid releases, derived release limits (DRLs) have been developed by Bruce Power to ensure release limits to the environment will not exceed the annual regulatory public dose limit of 1 millisievert (mSv). Furthermore, Bruce Power has established action levels that are set at approximately 10% of the DRLs. Action levels, if reached, could indicate a loss of control of part of Bruce Power’s environmental program and the need for specific actions to be taken and reported to the CNSC. In 2016, all releases were below the DRLs and action levels.

As a result, for the 25th consecutive year, Bruce Power’s calculated dose to a member of the public is less than the 10 microsieverts/year (µSv/y) value that is regarded as the lower threshold for significance. Dose to potential representative persons are calculated using IMPACT 5.5.1. The most recent site specific survey results (2011 Site Specific Survey), 2016 meteorological data, effluent and environmental monitoring data for the Bruce site for 2016 were all taken into account for the calculation. The highest dose estimated for year 2016 is 1.6 µSv/y, representing 0.16% of the regulatory dose limit of 1,000 µSv/y. The representative person estimated for year 2016 is the infant at the Bruce Mennonite Farmer 3 location.


Bruce Power complies with relevant Federal and Provincial environmental legislation, regulations and other requirements, specifically with regulations and programs which protect human health and the environment under the Canadian Environmental Protection and Nuclear Safety and Control Acts. Bruce Power also complies with the Environmental Compliance Approvals and Permits issued by the Ontario Ministry of Environment and Climate Change.

Bruce Power is registered to the ISO 14001 Environment Management System and uses it as our environmental framework, while also applying any applicable industry-best standards to allow us to continuously improve our performance, while minimizing our environmental impact, preventing pollution and achieving excellence.

ISO 14001:2015 was released by the International Organization for Standardization on Sept. 15, 2015. Bruce Power’s ISO 14001 registration is a requirement of the PROL, and Bruce Power is currently registered to ISO 14001:2004. ISO 14001:2015 focuses on the Environment Management System (EMS) being integrated throughout business processes to aid in the organization’s knowledge and understanding of external and internal issues, stakeholders’ needs and expectations, and risks and opportunities impacting the organization. The major themes are leadership and commitment of management, identification of risks/opportunities related to environmental aspects affecting interested parties, protecting of the environment beyond prevention of pollution, continual improvement of environmental performance, adoption of a lifecycle approach when determining environmental aspects, and internal/external communications. Bruce Power is working toward full implementation of ISO 14001:2015 with a third party registrar audit scheduled for Fall 2017.

Bruce Power continues to progress through its implementation plans of standards and guidelines on environmental management of nuclear facilities (CSA N288 Series); specifically for Canadian Standards Association (CSA) standards on Environmental Monitoring Programs (N288.4-10), Effluent Monitoring Programs (N288.5-11), Environmental Risk Assessments (N288.6-12). The current programs and activities already demonstrate compliance to these standards; further improvements are being made to ensure the standards are incorporated appropriately on a clause-by-clause basis. Bruce Power is working toward full implementation of these standards for the end of 2018.

Monitoring and risk assessment programs show there are no adverse impacts on the environment as a result of facility operations. Recently included in the implementation plan is a standard on Groundwater Protection (N288.7-15). A groundwater monitoring program already exists as part of the routine program and this is being reviewed to meet the specific clauses in this new standard. Monitoring shows there are no adverse impacts on groundwater as a result of facility operations. It is anticipated that implementation will be in the same general timeframe as the other CSA standards.

An Environmental Risk Assessment (ERA) Report was completed in December 2014 and was submitted to the Canadian Nuclear Safety Commission (CNSC) in January 2015.  In June 2016, Bruce Power received feedback from CNSC that this submission met the compliance requirement of N288.6. There were three main recommendations with respect to Indigenous engagement, morpholine exposure and validation of modelling results to verify assumptions, as well as 24 opportunities for improvement. The feedback will be used as another tool to improve the development, definition, and implementation of various environment program areas across the company. The feedback from the CNSC will be incorporated in a future revision of the ERA where appropriate; updates are on a five-year cycle unless a major change in facility operations necessitates a revision. The ERA is being updated in July 2017 in preparation for our 2018 License Renewal, which includes Major Component Replacement (MCR).

Fisheries Act

Since 2012, Bruce Power has been in discussions with the CNSC and Fisheries and Oceans Canada (DFO) with respect to the authorization requirements under the amended Fisheries Act [R-91] in light of the signed Memorandum of Understanding (MOU) between the two parties. Bruce Power has reviewed existing design of the facility for adequacy and has determined that original design meets industry standards for mitigation and protection of fish. However, as part of the definition in the Fisheries Act, the residual impact requires offsetting measures. Bruce Power has developed and implemented programs to ensure there is no unreasonable risk to fish and fish populations; this is additionally being documented in the application. A draft application, containing results from one year of monitoring, was submitted for technical review in February 2015. A second draft application, containing results from two years of monitoring and age-1 equivalent biomass, was submitted for technical review in September 2016. Discussions continued in 2016 with CNSC/DFO and Indigenous groups on calculation methodologies and offset projects. A final application will be submitted in May 2017.

Thermal Effects

Bruce Power has been in active dialogue with the CNSC and Environment and Climate Change Canada (ECCC) to ensure fish are being protected from the effects of thermal discharge of water. Much of the discussions in 2016 were centered on the appropriate characterization of the risk through the interpretation of thresholds and scientific knowledge compiled to date. The outcome of the discussions will be documented in the ERA to be submitted in July 2017.


Bruce Power manages many different forms of waste, including radioactive, hazardous (oils and chemicals), recyclables (glass, cardboard, plastic, paper, metal), organic (compost), and landfill (for those items that are not radioactive, non-hazardous, cannot be recycled or composted). Beyond complying with relevant waste regulations and requirements, reducing all forms of waste is in the best interest of the company from both an environmental and financial standpoint, and has been a focus for many years. The philosophy is to reduce at the consumer level, to generate less waste, reuse when opportunities are presented and explore all opportunities to sort and recycle. There are a number of initiatives that focus on these areas. Waste volumes are minimized by applying the principles of reduce, reuse, recycle, recover; and wastes are processed in a safe, environmentally responsible manner. Potential pollutants are controlled to meet regulatory requirements and to minimize environmental impacts associated with their use. Bruce Power continues to effectively implement programs for the minimization, segregation, handling, monitoring and processing of waste in accordance with regulations and industry best practice.
