Introduction
Encana Corporation (the “Responsible Party”) engaged Brightspot Climate Inc. (Brightspot Climate) to
review their greenhouse gas (GHG) emission reduction and removal projects, Vent Gas Capture
Aggregation Project, Vent Gas Capture Aggregation Project Phase 2, and Vent Gas Capture
Aggregation Project Phase 3 (collectively, the “Projects”). The Projects were developed in accordance
with the Quantification Protocol for Engine Fuel Management and Vent Gas Capture Projects, Version
1.0, October 2009 (the “Protocol”).
The Responsible Party’s “GHG Assertion” is comprised of the Offset Project Plan, Offset Project Report
and supporting documentation for each Project. The GHG Assertions cover the reporting period
January 16, 2015 – July 31, 2016 and states an emission reduction and removal claims as follows:
GHG Emission
Reduction
Encana Corporation’s Vent Gas Capture
Aggregation Project
2015: 25,621 tonnes CO2e
2016: 15,689 tonnes CO2e
Encana Corporation’s Vent Gas Capture
Aggregation Project Phase 2
2015: 5,971 tonnes CO2e
2016: 4,195 tonnes CO2e
Encana Corporation’s Vent Gas Capture
Aggregation Project Phase 3
2015: 23,277 tonnes CO2e
2016: 13,572 tonnes CO2e
The Responsible Party is responsible for the preparation and presentation of the information within the
GHG Assertions. Our responsibility as the verifier is to express an opinion as to whether the GHG
Assertions are materially correct, in accordance with approved Protocol, the Specified Gas Emitters
Regulation (Alta. Reg.139, 2007) (the “Regulation”), and the Alberta Environment and Parks Technical
Guidance for Offset Project Developers, Version 4.0, February 2014.
Scope
We completed our review in accordance with the ISO 14064 Part 3: Greenhouse Gases: Specification
with Guidance for the Validation and Verification of Greenhouse Gas Assertions (ISO, 2006). As such,
we planned and performed our work in order to provide positive, but not absolute assurance with
respect to the GHG Assertion.
The verification procedures that were performed through the course of the verification were developed
based on the results of a risk assessment that was completed during the verification planning stage.
These verification procedures are described in the Verification Plan. Certain verification procedures
included data sampling. The sampling type, sample size and the justification for the planned sampling
type and size are detailed in a Sampling Plan, which is included in the Verification Plan.
Conclusion
I believe our work provides a reasonable basis for my conclusion.
There were no unresolved discrepancies detected in the final GHG Assertion.
Based on our review, it is my opinion at a reasonable level of assurance that the GHG Assertion is
materially correct and presented fairly in accordance with the relevant criteria.
Sincerely,
Aaron Schroeder, P.Eng.

Parties Associated with the Verification
ISO 14064-3 defines the following terms used in the context of a GHG verification:
GHG Assertion: a declaration or factual and objective statement made by the Responsible
Party.
The Alberta Environment and Parks Technical Guidance Document extends this definition to
include the information included in the Baseline Emissions Inventory Application and the
Specified Gas Compliance Report.
GHG Project: activity or activities that alter the conditions identified in the baseline scenario,
which cause GHG emission reductions or GHG removal enhancements.
The GHG Projects that are the subject of this verification are Vent Gas Capture Aggregation
Project, Vent Gas Capture Aggregation Project Phase 2, and Vent Gas Capture Aggregation
Project Phase 3, which will be referred to throughout this document collectively as “the
Projects”.
ISO 14064-3 defines the following parties associated with the verification:

Responsible Party: person or persons responsible for the provision of the greenhouse gas
assertion and supporting GHG information.
The Responsible Party for this verification is Encana Corporation.
Intended User: individual or organization identified by those reporting GHG-related information
as being the one who relies on that information to make decisions.
The Intended User for this verification is Alberta Environment and Parks.
Verifier: competent and independent person, or persons, with responsibility for performing and
reporting on the verification process.
The Verifier for this verification is Brightspot Climate Inc. The members of the verification team
are provided in section 3 of this document.
Principles
ISO 14064-3 defines four fundamental principles to conducting a greenhouse gas verification, namely
independence, ethical conduct, fair presentation and due professional care.
Brightspot Climate has implemented processes, including requiring appropriate training for all
verification team members, to ensure the application of these principles for this verification.
A final “Conflict of Interests Checklist” is included in Section 6 of this report.
Project Description
The Projects reduce emissions of greenhouse gases at natural gas compressor stations by utilising
“SlipStream” technology that captures and combusts natural gas that otherwise would have been
vented to the atmosphere from various control devices. The technology directs this vent gas into the air
intake of a reciprocating engine where it is combusted as a supplemental fuel source.
The Projects are an aggregation of installations at multiple project sites.
Metered data is collected from each project site using a centralized SCADA system. Gas composition is
analyzed annually in a third-party laboratory for each project site.

PROTOCOL APPLICABILITY REQUIREMENTS
Determination of brake
specific fuel consumption
Not applicable for this project.
Functional equivalence
must be demonstrated;
engine performance must
not be impaired because
of the project
Substantive test: Observe operations and
interview operations staff during site visit to
determine level of service provided by
project implementation.
During the site visit, the verification team observed the vent gas
capture systems and found that an equivalent level of service is
provided by all installations and that these installations do not impair
the engine performance.
When the vent gas capture systems are not operational, gas is
vented, equivalent to the baseline condition. This vented gas is not
metered and therefore, it is appropriately excluded from the
emission reduction calculation.
Site staff indicated that following the commissioning stage, the
systems work well. Ongoing maintenance is performed during
regular maintenance of the full facility.
No discrepancies detected.
Capture of vent gas must
not be required by
regulation
Substantive test: Review the daily gas
volume captured for each site and compare
against the Directive 60 requirements. If
necessary, review the economic analysis
defined in Directive 60 for each site.
Vent gas volumes for each site are well below the thresholds that
require capture, which are described in Directive 60.
No discrepancies detected.
The project must comply
with all air emission
regulations in Alberta
Substantive test: Review the daily gas
volume captured for each site and compare
against the Directive 60 requirements.
Vent gas volumes for each site are well below the thresholds that
require capture, which are described in Directive 60.

captured from glycol dehydrators and if the
requirements of Directive 60, Section 8.3
apply, which may disqualify the site.
The verification team confirmed that this requirement is not
applicable because there are no glycol dehydrators located on the
sites included in the project.
No discrepancies detected.
Projects must use “flaring”
as the baseline condition if
flaring is required by any
regulation.
Refer to the Protocol Applicability requirement, “Capture of vent gas must not be required by regulation”, above.
The project must not
occur within the boundary
of a site that is regulated
by the Specified Gas
Emitters Regulation.
Substantive test: Compare the project
locations to the list of facilities regulated by
the Specified Gas Emitters Regulation.
Based on the analysis of the verification team, none of the project
sites are within the boundary of facilities regulated by the Specified
Gas Emitters Regulation.
No discrepancies detected.
Quantification must be
based on actual
measurements and
monitoring.
Substantive test: Review quantification data
for anomalies or missing data.
All data used to quantify the emission reduction are metered values
(refer to the Quantification Data section of this table for further
details regarding the specific data used to quantify the emission
reduction).
An analysis of the datasets used for quantification did not reveal any
anomalous data.
No discrepancies detected.

The project must meet the
requirements of the
Alberta Offset System
Substantive test: Evaluate the project
developer’s evidence regarding the general
requirements of the Alberta Offset System.
Occurs in Alberta – all sites in the aggregated project are within
Alberta, as confirmed by project documentation.
Actions not otherwise required by law – confirmed that none of
the sites are defined as “regulated facilities” under the Specified
Gas Emitters Regulation. No other regulatory requirements were
found to apply to the project activity for the sites in the aggregated
project.
Actions taken on or after January 1, 2002 – commissioning of all
instrument air systems occurred after this date, as confirmed by
project documents and inquiries of site operations staff.
Real, demonstrable, quantifiable – the verification procedures
confirmed that the emission reductions in the aggregated assertion
meet these requirements. The specific verification procedures
supporting this conclusion include observation during the site visits,
review of supporting meter calibration reports and documentation
and the recalculation of the emission reduction.
Clearly established ownership – Encana and Ember are the
majority owners for each of the sites and Ember has authorized
Encana to act as the primary Responsible Party for the purpose of
quantification and reporting of the GHG emission reduction. One
minority owner has signed documents establishing ownership of
the emission reduction relative to their ownership in the respective
sites.
Counted once for compliance purposes – The Responsible Party
provided a Statutory Declaration that the emission reduction will be
registered only in the Alberta Offset System.
No discrepancies detected.

Terminology
ISO 14064-2 defines the following terms used in the context of a GHG verification:
GHG Assertion: a declaration or factual and objective statement made by the Responsible
Party.
The Alberta Environment and Parks Technical Guidance Document1 extends this definition to
include the document that identifies the greenhouse gas emission reduction and/or removals
and offset credits being claimed by the offset project over a defined period.
Project: activity or activities that alter the conditions identified in the baseline scenario which
cause greenhouse gas emission reductions or greenhouse gas removal enhancements.
The GHG Assertion subject of this verification is Encana Corporation’s Vent Gas Capture
Aggregation Projects, namely:
• Encana Corporation’s Vent Gas Capture Aggregation Project
• Encana Corporation’s Vent Gas Capture Aggregation Project Phase 2
• Encana Corporation’s Vent Gas Capture Aggregation Project Phase 3
Collectively, these three emission reduction projects will be referred to throughout this proposal
as “The Projects”.
ISO 14064-2 defines the following parties associated with the verification:
Responsible Party: person or persons responsible for the provision of the greenhouse gas
assertion and supporting GHG information.
The Responsible Party for this verification is Encana Corporation (Encana).
Intended User: individual or organization identified by those reporting GHG-related information
as being the one who relies on that information to make decisions.
The Intended User for this verification is Alberta Environment and Parks (AEP).
Verifier: competent and independent person, or persons, with the responsibility of performing
and reporting on the verification process.
The Verifier for this verification is Brightspot Climate Inc. (Brightspot Climate). The members of
the verification team are provided in section 3 of this document.

Introduction
This document serves to communicate information between the parties associated with the
independent verification of the Offset Project Report for Vent Gas Capture Aggregation Projects.
This document contains three sections:
1. The introduction, which defines the principles by which this verification will be conducted;
2. The GHG Assertion, which describes the subject matter of the verification; and
3. The Verification, which defines the verification parameters and the GHG inventory principles that
will be tested by the verification. This third section also provides information regarding the
verification team and any findings from previous verifications for the Projects.
The verification procedures, including the sampling plan and the results of the verification risk
assessment, will be appended to this verification plan in the final verification report.
The Responsible Party developed the Projects in accordance with the requirements of the Alberta
Government’s Quantification Protocol for Instrument Gas to Instrument Air Conversion in Process
Control Systems” Version 1.0, October 2009 (the Protocol).
Principles
ISO 14064-3 defines four fundamental principles to conducting a greenhouse gas verification, namely
independence, ethical conduct, fair presentation, and due professional care.
Brightspot Climate has implemented processes, including mandatory training for all verification team
members, to ensure the application of these principles for this verification.
Regarding the principle of independence, Brightspot Climate assessed threats to independence prior to
initiating this verification. No real or perceived threats to independence were identified. Brightspot
Climate will continue to monitor for threats to independence throughout the course of this verification. A
final “Conflict of Interests Checklist” will be appended to the Verification Statement.

GHG Assertion
Projects Subject Matter
The Technical Guidance Document2 defines “subject matter” in Section 2.2.3.2 as follows:
“The subject matter for an offset project is the greenhouse gas emissions from the offset project
and baseline, including the total greenhouse gas emission reduction, and/or removals achieved
by the offset project that can be appropriately evaluated against the program criteria.”
The subject matter for the Projects is defined in the verification scope, which is described in Table 4.
GHG Assertion
The Responsible Party’s asserted emission reduction is provided in the following table:
Table 1: Baseline and Previous GHG Assertions

Changes to Operations and Boundaries
This is the first year that Brightspot Climate has provided verification services for the Projects.
In 2015, Encana sold several sites in each of the Projects to Ember Resources Inc. (Ember). Encana
and Ember entered an agreement on November 10 that nominated Encana to register, coordinate
verification and serialize all emission reductions across the projects. Encana and Ember have a
commercial agreement to reconcile offset ownership after serialization of the offsets is complete.
Additionally, Canstone Energy Ltd. (Canstone) hold a minority interest in some of the project sites.
Canstone entered an agreement with the majority owner of these sites, nominating Encana with the
right to serialize all emission reductions for Canstone’s project sites.

Verification
Principles
ISO 14064-2 defines six principles that are fundamental to the fair accounting and reporting of GHG
information. The verification procedures will test that these principles have been upheld through the
Responsible Party’s inventory, accounting and reporting processes.
Section 3.2 – 3.6 of ISO 14064-1 defines these principles as follows:
Accuracy: reduce bias and uncertainty as far as practical
Completeness: include all relevant emission sources
Conservativeness: use conservative assumptions, values and procedures to ensure that GHG
emission reductions or removal enhancements are not over-estimated
Consistency: enable meaningful comparisons of reported emissions (from year to year or
between facilities or between companies)
Relevance: select GHG sources, sinks and reservoirs, data and quantification methodologies
appropriate to the needs of the intended user
Transparency: disclose sufficient and appropriate GHG information to facilitate verification and
to allow intended users to make decisions with relative confidence
Verification Parameters
The verification will be conducted according to the parameters defined in the following table:

Materiality Quantitative materiality threshold is 5% of asserted greenhouse gas
emission reduction
Tolerable Error
Thresholds
An unqualified verification conclusion may be issued despite immaterial
quantitative discrepancies that do not exceed the materiality threshold in
aggregate (calculated as both net and gross overall discrepancy).
The tolerable error threshold per issue in either the baseline or project
condition will be graduated as follows for emission sources:
• 2% for emission sources greater than 50% of total baseline or
project emissions;
• 5% for emission sources between 20% and 50% of total baseline
or project emissions; and
• 10% for emission source less than 20% of total baseline or project
emissions.
All discrepancies will be described in the Verification Report.

Verification Risk Assessment and Verification Procedures
The Verification Risk Assessment was completed prior to issuing the draft version of this document.
Verification procedures were developed to reduce the overall verification risk to facilitate the objectives
of the verification. Each inherent and control risk is provided with the risk evaluation (high/medium/low).
The risk evaluation considers both the magnitude of the activity data or inventory component on the
overall GHG assertion as well as the probability that the risk will result in a discrepancy, as assessed by
the verifier.
In instances where a substantive approach is applied in the verification procedure (i.e. the procedure
tests the data, rather than the Responsible Party’s controls), the Responsible Party’s control is not
listed, but is denoted “N/A”; however, this does not imply that the Responsible Party does not have a
control in place.
Verification risk is defined as the risk of an incorrect verification conclusion. It can be calculated as the
product of the Projects’ inherent risks, the Responsible Party’s control risks and the Verifier’s detection
risks. The verifier cannot affect the inherent risk or the control risk. Therefore, to reduce the overall
verification risk and reach the agreed level of assurance (defined in the verification scope), the verifier
must design verification procedures that reduce the detection risk.
