Footnote A:
Production stated is net bitumen sales. The net volume is used to calculate emission intensities as it represents emissions associated with total plant saleable product. In 2014, production increased mainly due to this being the first full year of operations from all four stages of Firebag’s operations.

Footnote B:
Greenhouse gas (GHG) emissions are calculated using a facility-specific methodology which utilizes various reference methodologies that have been accepted by the relevant jurisdictions each facility is required to report its GHG emissions.  Methodology has been followed where a jurisdiction has a prescribed one and if none exists then the most applicable and accurate methods available are used to quantify each emission source.

GHG emissions and emissions intensity values are consistent with Suncor’s Specified Gas Emitter’s Regulation (SGER) Bill 3 reported Total Annual Emission (TAE) value, with an exception. The reported TAE in the SGER Compliance report excludes CO2 emissions from total indirect sources, such as the third-party cogen at MacKay River.

Firebag data in this report includes all cogen emissions as Scope 1. MacKay River data includes the portion of third-party cogen emissions associated with the steam and electricity we consume as Scope 2. Beginning in 2014 and amended in 2015, MacKay River implemented a new methodology for calculating these indirect emissions; therefore all reported data has been calculated using this method.

Footnote G:
Total energy is equal to the sum of direct and indirect energy. It includes combustion of natural gas and internally-produced fuels, flaring and electrical power imports. For MacKay River, exported electricity sent to the grid from the third party cogen is not claimed as an indirect; only the power consumed by Suncor Operations since the cogen is independently operated by TransCanada. For Firebag, the exported electricity to the grid is deducted from the total energy use since the cogen is operated by Suncor. Direct energy consumption is calculated using lower heating value (LHV) in order to be consistent with all other operating facilities.

Footnote H:
Direct energy is primary energy consumed on-site by Suncor operated facilities; it includes combustion of natural gas and internally produced fuels. 

Indirect energy includes imported electricity, steam, heating and cooling duty from third parties.

The indirect energy calculation methodology credits operations for electricity exported to external users and/or other Suncor facilities. The facility that exports the electricity subtracts the value from their indirect energy use. The facility that receives the electricity counts it as a Scope 2 indirect energy use, regardless of source. As such, Firebag indirect energy figures are negative, because the amount of electricity exported was higher in value than the amount of electricity imported. The negative Firebag indirect energy figures for 2013 and 2014 are higher than the MacKay River indirect energy figures, which is why the In Situ total indirect energy figures are negative for these years. For Firebag, the exported electricity (regardless of destination) is deducted from the indirect energy use since the cogen is operated by Suncor. For MacKay River, only the imported electricity (regardless of source) is reported as indirect energy use. Power sold to the grid by the MacKay River TransCanada cogen is not included in this number.

Footnote L:
Waste that is sent to deep well injection is primarily related to blowdown from our SAGD operations at Firebag consisting of concentrated water impurities that accumulate during the steam generation process. This boiler feed water is intentionally wasted from the boilers to avoid concentration of impurities during continuing evaporation of steam. Deepwell disposal methods of this nature are safe, viable and part of normal operating parameters and our operations are within the disposal limits for these waste streams (regulated by the Alberta Energy Regulator). Our operations also have exceptionally high water recycle rates, above regulated levels.

Hazardous waste landfilled is primarily off-spec warm lime sludge, created by upset. The period of time dealing with upset conditions at Firebag was a matter of weeks in 2013, compared to several months in 2014.

A Production stated is net bitumen sales. The net volume is used to calculate emission intensities as it represents emissions associated with total plant saleable product. In 2014, production increased mainly due to this being the first full year of operations from all four stages of Firebag’s operations.

Greenhouse gas (GHG) emissions are calculated using a facility-specific methodology which utilizes various reference methodologies that have been accepted by the relevant jurisdictions each facility is required to report its GHG emissions.  Methodology has been followed where a jurisdiction has a prescribed one and if none exists then the most applicable and accurate methods available are used to quantify each emission source.

GHG emissions and emissions intensity values are consistent with Suncor’s Specified Gas Emitter’s Regulation (SGER) Bill 3 reported Total Annual Emission (TAE) value, with an exception. The reported TAE in the SGER Compliance report excludes CO2 emissions from total indirect sources, such as the third-party cogen at MacKay River.

Firebag data in this report includes all cogen emissions as Scope 1. MacKay River data includes the portion of third-party cogen emissions associated with the steam and electricity we consume as Scope 2. Beginning in 2014 and amended in 2015, MacKay River implemented a new methodology for calculating these indirect emissions; therefore all reported data has been calculated using this method.

G Total energy is equal to the sum of direct and indirect energy. It includes combustion of natural gas and internally-produced fuels, flaring and electrical power imports. For MacKay River, exported electricity sent to the grid from the third party cogen is not claimed as an indirect; only the power consumed by Suncor Operations since the cogen is independently operated by TransCanada.

The facility that exports the electricity subtracts the value from their indirect energy use. The facility that receives the electricity counts it as a Scope 2 indirect energy use, regardless of source. As such, Firebag indirect energy figures are negative, because the amount of electricity exported was higher in value than the amount of electricity imported. The negative Firebag indirect energy figures for 2013 and 2014 are higher than the MacKay River indirect energy figures, which is why the In Situ total indirect energy figures are negative for these years. For Firebag, the exported electricity (regardless of destination) is deducted from the indirect energy use since the cogen is operated by Suncor. For MacKay River, only the imported electricity (regardless of source) is reported as indirect energy use.

This boiler feed water is intentionally wasted from the boilers to avoid concentration of impurities during continuing evaporation of steam. Deepwell disposal methods of this nature are safe, viable and part of normal operating parameters and our operations are within the disposal limits for these waste streams (regulated by the Alberta Energy Regulator). Our operations also have exceptionally high water recycle rates, above regulated levels.

Hazardous waste landfilled is primarily off-spec warm lime sludge, created by upset. The period of time dealing with upset conditions at Firebag was a matter of weeks in 2013, compared to several months in 2014.

Otherwise disposed includes cavern and ecopit disposal.

A reclassification of waste streams would result in the value of deep well injection in 2014 revised to 1,000,671 tonnes and 54,577 tonnes otherwise disposed in 2014 for a total hazardous waste generated value of 1,056 thousand tonnes in 2014.

M Includes sewage sent to Fort McMurray.
N This is hazardous and non-hazardous drilling waste. There were no drilling programs at Firebag or MacKay River in 2016.
O Beginning in 2012, drilling waste with greater than 8% bitumen content, hauled to the mine for re-processing, is no longer reported as waste reused onsite but has been captured in the OG7 indicator.
P Total land holdings approved for development is consistent with the Government of Alberta’s Environmental Protection and Enhancement Act (EPEA) approved footprint for our Firebag and MacKay River in situ production operations, as mapped by GIS internally. Meadow Creek East is approved but not yet reported because no production is occurring.

Total land disturbed is the total active footprint of our approved in situ projects, which includes the cumulative hectares (ha) for areas cleared, disturbed, ready for reclamation, soils placed and permanently reclaimed. This is used to represent all land area that has been or is currently disturbed at our in situ projects.

Land reclaimed is land that is no longer being used for in situ production purposes and has been, or is in the process of being, reclaimed. This value is a subset of the total active footprint. The area of non-reclaimed land at our in situ operations is 1,417 ha for the 2016 reporting year. Reclamation is tracked as the cumulative area reclaimed. As such, the total number of hectares reported from year to year may increase or decrease based on activities undertaken at the site since these activities may lead to new reclamation or re-disturbance of previously reclaimed areas. Reclaimed lands have not been certified by government regulators. See Advisories.
Q Some wells (core holes) identified as inactive operated wells in 2013 were incorrectly categorized as such.
R A regulatory contravention is an environmental incident that breaches a regulatory limit (prescribed threshold required by legislation, approval or permit from a regulatory authority) or requirement (any law, act, regulation, licence, standard, approval, directive and/or permit applicable to Suncor’s activities) and that triggers formal regulatory reporting.
S Data includes regulatory fines related to environmental, health and safety contraventions paid during the stated year.
T A reportable spill is an unplanned or accidental event resulting in a release of material either into the environment or into a location that does not usually contain the material, as specified by Alberta regulation.
U

In 2014, regulations placed greater emphasis on spill reporting, resulting in a greater emphasis on spill reporting, including contractors.
2015: Volume of hydrocarbon spilled to soil was 261 m3; no hydrocarbon spills to water.

In Situ social footnotes
V A lost-time injury requires medical attention and results in an employee being absent from work on the next regularly scheduled workday or any subsequent workday. Lost-time injury frequency is the number of such injuries per 200,000 hours worked, divided by the number of exposure hours.
W Recordable injuries include lost-time injuries as well as medical aid injuries. Medical aid injuries require medical attentions but do not result in an employee being absent from work. Recordable injury frequency is the sum of lost time and medical aid injuries per 200,000 hours worked, divided by the number of exposure hours.
X Compares In Situ full-time base wage to the province of Alberta's minimum wage ($12.20/hour in 2016).
Y Beginning in 2014, this indicator is reported Suncor-wide.
Z

Any externally-hired regular full-time or regular part-time employee whose permanent start date falls within the reporting period.
