1. PURPOSE OF PLAN
The Detour Gold Project Spill and Environmental Emergency Response Plan (SEERP)
establishes procedures for responding to spills to water and soil including all emergency spills at
Detour properties and travel ways that may jeopardize the health or safety of personnel, the
natural environment, and/or property. The SEERP addresses potential emergencies identified
through site risk assessments.
The SEERP has been developed to meet current regulations (Federal Metal Mining Effluent
Regulation, E2 Environmental Emergency Regulations), and will be updated as required by the
outcome of environmental incidents, changes in activities, legislation or policies. At a minimum,
the procedures related to spills are reviewed annually and updated as required.
The SEERP is designed to promote effective response with minimal confusion and disruption of
activities at Detour sites. It is constructed so that it can be initiated and operated by "on duty"
personnel until such time as additional personnel support is required. The plan is also intended
to define responsibilities, outline a training plan and to establish priorities for essential activities.
In addition to satisfying regulatory requirements, this Plan is to be used as a working document
at the facility. The Plan should be used frequently in the following ways:
As a reference for storage and containment information
As a tool for informing new employees and refreshing existing employees on practices
for preventing and responding to spills
As a guide to periodic training programs for employees
As a guide to facility inspections
As a resource during an emergency response
It should be noted that not all situations can be foreseen, thus this Plan can only serve as a
guide in establishing proper organization at the time of an environmental emergency. The Site
Emergency Management Team (SEMT) must consider the detailed response to any situation
based on the information available at the time of the emergency.
The guidelines, policies and procedures in this Plan should ensure that all emergencies will
require immediate action as necessary, with priorities of:

Protecting lives and preventing injury;
Protecting the environment;
Protecting property; and
Minimizing disruption or interference with the business activities of Detour Gold Corp.
The main objectives of the Plan are:
To ensure the earliest possible response and overall control of the emergency
operations;
To undertake immediate actions to eliminate all sources of potential danger within the
affected area;
To ensure that impact to the natural environment is minimized;
A structured and cohesive control group is formed in the event of an incident to
maximize efforts and minimize confusion;
All applicable government legislation is complied with by following initial response
procedures as soon as a spill is identified;
A fully equipped and trained response team is available to deal with minor and major
spills of a hazardous material;
That all required PPE and equipment is available;
An internal incident reporting system and follow-up reporting system is in place to obtain
and document the facts of the incident and possibly reduce future incidents;
To provide timely, factual, and official information to the SEMT, media, public, and
individuals seeking personal information;
Any detrimental impacts or clean-up costs a spill or discharge may have are minimized.
The SEERP is a stand-alone document created to satisfy regulatory requirements; however the
plan should be implemented and implemented in conjunction with the main site E.R.P.

2. SCOPE
The SEERP applies to the Detour Lake Mine site and associated sites in Cochrane as well as
HWY 652 and the mine site access road. It applies to all surface activities involving both
contract personnel as well as employees. This document outlines measures to prevent and
respond to environmental emergencies related to spills of environmentally hazardous materials
throughout the DLM site area. Understanding and following these procedures will minimize
environmental damage and health and safety risks throughout the project area.
The SEERP outlines how spills are to be reported and the sequence of responses that are to
occur as a result of the spill. It refers to key contacts at the DLM site and in the closest
communities.
The following emergencies are considered in this plan:
1. Hydrocarbon spills on land
2. Hydrocarbon spills on water
3. Hydrocarbon spills on snow & ice
4. Failure/spill/seepage/overtopping from Tailings dam
5. Pit Dewatering and Sump Dewatering pipelines with focus on a breach at Easter
Creek/Karel Creek Crossings.
6. Stockpile run-off & seepage collection system overflow
7. Sedimentation pond overflow
8. Grey water and sewage spills from the Sewage Treatment Plant or related infrastructure
9. Explosives (ammonium nitrate) spills
10. Propane Spills
11. Offsite Road spills on HWY 652/Cochrane
12. Chemical spills in the mill area (e.g. cyanide, SO2, caustic soda)
13. Tailings Pipeline Rupture
For more information on how the above mentioned emergencies were qualified please refer to
the risk assessment in Appendix 1.

These spill emergencies will be added to this plan as the risks become applicable to Detour’s
Operations.
3. SITE ACCESS
The Detour Lake Property is accessible 24 hr/7 days/week, year round by travelling northeast
on Provincial Highway #652 from the Town of Cochrane. The highway turns into a 40 km gravel
road that will lead to the DGC Security Gate. Sites are equipped with First Aid/Security
attendants, and sign-in/site orientation is required for all personnel.
4. REGULATORY REQUIREMENTS
This SEERP complies with the following provincial and federal regulation
O.Reg 675/98 - Classification and exemption of spills and reporting of discharges
O.Reg 560-94 - Effluent Monitoring and Effluent Limits-Metal Mining Sector (not yet
applicable)
Metal Mining Effluent Regulations (SOR/2002-222)
Environmental Emergency Regulations (SOR/2011-294)
5. SPILL PREVENTION
As part of the spill prevention portion of the plan analysis has been undertaken for various
substances on site that could be spilled, leaked or released that may cause an adverse
effect. These substances have been identified; prioritized based on magnitude of potential
environmental impact as well as relevant spill prevention steps have been/will be
implemented.
5.1 Hazard Identification
For each hazardous substance and potential related spill hazard scenario on site, the
hazard identification review has been completed. The hazard identification process
considers information on the toxicological, physical and chemical properties of the

substances being handled. The potential impact on downwind air quality or downstream
water quality from accidental release and danger to human and animal health is also
considered. Emergencies caused by human impact such as fire, explosion, transportation
accidents, pipeline breaks or equipment failure are also considered in addition to the natural
disasters such as earthquakes, floods or landslides.
The Hazard Identification includes the following as part of the assessment:
Chemical name, alternate names
Potential receiving environment for the spill (air, land, water, groundwater)
Storage location, maximum quantity stored, location of use
Chemical characteristics, properties
Product usage (storage, handling, processing and disposal)
Likelihood of a spill, nature and extent of adverse effect
Where the chemical is used in relation to surface water body, floor drains, indoors,
secondary containment
Potential routes to natural environment during storage, transport, handling,
processing
Summary of potential initiating events (human error, natural disaster, equipment
failure)
History and trends of spills
Engineering and Operational Controls to prevent spills from occurring
5.2 Probability/Likelihood Analysis
Following the identification of the hazards, the probability or likelihood of the spill hazard
event is determined. The probability is defined using a quantitative ranking of the frequency
of occurrence of a hazardous event.
The following factors are considered when determining the probability/likelihood value:

The impact analysis provides a severity score which ranges between 1-5. Based on the score obtained the consequence is ranked using the table shown below. 5.4 Risk Analysis
The use of the frequency and impacts ranking system allows each hazard to be assessed logically and systematically. The Overall Risk Ranking for each substance/scenario is obtained by multiplication of the probability rank index by the impact index. For more information of risk ranking and analysis consult IMS-SOP-004 Risk Analysis Procedure as well as HST-SOP-005 Job Hazard Analysis Procedure. A hazard ranking of 25 represents a very high risk that requires immediate mitigation, and a hazard ranking of 1 represents an insignificant risk that requires no specific mitigation. Below is the risk-ranking matrix:

Detour Gold considers all hazard scenarios with a risk ranking of greater than H16
“significant risks”, therefore more information is required. For each spill assessed to be of
significant risk additional spill reduction or prevention steps will be identified and
documented.
These may include:
Identification of possible steps that could be taken to prevent or reduce the risk of the spill from occurring

Note which of these steps have been or will be taken to prevent or reduce the risk of the spill from occurring, including consideration of the appropriateness of such things as:
Constructing or installing containment structures
Installing and maintaining mechanisms or equipment to monitor these operations at the site (alarms, notification systems)
Altering or redesigning industrial processes used at the site to prevent or reduce the risk of spill, or installing equipment for the purpose
For the possible steps that have not been and will not be taken, provide an explanation of that decision
Hazard scenarios with a score of H16 should be reviewed and a determination made on a case-by-case basis whether these scenarios represent a “significant risk”. To further reduce risk DGC encourages all employees to provide information concerning weaknesses in systems or operating procedures, “near misses”, and potential problems they have observed, along with recommendations to supervisors and management to prevent/mitigate such occurrences. All risk assessments are documented in Appendix 1.

7.1 Discovery of Spill and Initial Assessment:
The First Person at the scene of a spill (“Controller”) shall assess the situation and ask
themselves the following questions:
What is the spilled material? Is it hazardous (i.e. toxic, corrosive, flammable,
reactive)?
What is the source of the spill?
What is the cause of the spill?
Is the spill an internal (indoor) spill or external (outside) spill?
7.2 Level of Response
The First Person at the scene of a spill (“Controller”) shall assess the level of response
required to mitigate the situation by asking themselves the following questions:
Are there any injuries? / Is there potential for injury?
Is the spill >1000 L? Is the material toxic or hazardous?
Will controlling the spill require more than 3 people?
Has the spill occurred in open water and/or is there a risk that the spilled
material can enter open water (eg creek, river, lake) or the tailings or
sediment holding ponds
Can/has the spill caused extensive damage to the environment?
Is it too dangerous to stop the spill safely (e.g. fire, fumes, obstruction to
access)
Is there insufficient not enough spill response equipment readily available to
contain the spill and/or immediately to prevent it from entering the
environment?
If the First Person at the scene of a spill (“Controller”) answers ‘yes’ to any of the above
questions they will proceed immediately to follow the steps in Section 8.
If the First Person at the scene of a spill (“Controller”) answers “no” to all of the above
questions they will proceed with General Spill Response as per section 7.3 below (Tab
A).

process to Environmental Department and First Aid /Security as appropriate
Wear appropriate personal protective equipment (PPE) when cleaning
potentially hazardous substances.
Contain the spilled material using spill response kits and/or equipment
immediately to prevent it from entering the environment and help with clean
up. (For information on spill response materials consult Section 7 Spill
Response Equipment Inventory and User Guide)
Clean-up. Place all used absorbents and spill materials into an approved
205 L (45G) drum or other container (eg. Veolia wheeled tote). If possible,
make sure drums are on a pallet prior to filling.
Label the drum or tote with the name of the spilled material inside and the
date (eg. Oily pads, June 16, 2013)
Place the contaminated drums and or totes in an approved location or
contact the appropriate department (eg. Infrastructure Maintenance) to
have them picked up.
Report. Assist your supervisor and/or the environmental personnel in
completing a spill report form and submit to environmental department.
Investigate causes and determine corrective/preventive actions
Stop techniques may include:
Turning off pumps
Shutting valves

8. EMERGENCY SPILL RESPONSE PROCEDURE
If the answer to one of the questions in section 7.2 was YES, the spill is now classified as an
emergency spill and will likely require additional resources to manage the response. The
controller of the spill will initiate the following procedure.
Stay a safe distance away from the spill area, if it is not possible to safely stop the
source of spill.
Notify Shift Supervisor
In the event that personnel cannot reach their Supervisor, they are responsible for
reporting the spill to the Environment department as soon as possible.
Wear appropriate PPE (eg. Ty-chem suits, goggles, face shield)
Attempt to stop the spill if safe to do so
Contain the spilled material if possible and wait for additional resources
8.1 Reporting a Spill by Phone An emergency spill must be reported to the Environmental Departments by phone or by radio. The procedure to report an emergency to the Environmental Departments by phone is as follows:
