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:


Document Number

ENV-PLN-001-V8





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.


Document Number

ENV-PLN-001-V8





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


Document Number

ENV-PLN-001-V8





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.

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


Document Number

ENV-PLN-001-V8





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. ASSESSING THE LEVEL OF RESPONSE

Upon discovering any spill, personnel discovering or causing a spill shall isolate the area to

restrict access to the spill and to minimize the possibility of personal exposure and prevent

unnecessary contamination. The intent of the spill response procedure is to provide an

organizational structure that can be initiated at any time – 24 hours per day; 7 days per week.


Document Number

ENV-PLN-001-V8





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).


Document Number

ENV-PLN-001-V8





7.3 General Spill Response

Stop the spill safely, if it is possible.

Notify your Shift Supervisor or designate who will initiate notification

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

Turning off motors

Plugging hole and leaks

Cutting supply of spilling substance

Containment techniques may include:

Earth berms

Ditching

Sand bagging

Deploying booms

Deploying turbidity curtains

ENV-PLN-001-V8





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:

1) Call these extensions below in order until you are able to reach someone:

The overall emergency procedures including what to do in response to environmental

emergencies will be communicated through training. All personnel will receive project induction

training prior to commencing work on site, as part of their site orientation. In addition, refresher

training will be conducted when significant changes to the site emergencies have been made, or

at a minimum, as required to ensure ongoing awareness of the site emergency response

procedures.


Document Number

ENV-PLN-001-V8





Initial training for parties with specific responsibilities listed in the SEERP will be completed as

part of an awareness session to make all parties aware of their involvement, expectations and

responsibilities as they relate to SEERP.

An Emergency Response Team (ERT) has been established and will be trained by Detour’s site

Environmental Managers/Coordinators or by an outside consultant. These individuals will be

trained in spill response procedures and will be shown where spill equipment is stored and how

it is used. The ERT will be trained on WHMIS documentation related to products on site likely to

trigger an emergency response.

Heavy Equipment Operators required to assist with heavy equipment have training specific to

the equipment that they will be using to assist in emergency response.

10.1 Drills

At least 1 drill (tabletop or live) related to water emergencies (eg. Dam overtopping, deposit of a

deleterious substance) is completed annually as required by various legislation (Federal Metal

Mining Effluent Regulation, Federal E2 Environmental Emergencies Regulation). The drill is to

be reviewed, with any recommendations incorporated into the plan. Drills are to be conducted

by the Environmental Manager and the Detour Emergency Response Team and may occur at

the DLM site or on a mine related road. For more information please see Appendix 7

the spilled material inside and the date (e.g. Oily pads, June 16, 2013) for appropriate

manifesting and offsite disposal at an approved site. An approved hazardous waste hauler will

come to site on a pre-determined schedule for periodic waste pick ups for disposal off site.

Hydrocarbon contaminated soil shall be transported to the designated area in the landfill once

authorization is received from the environment department, sampled for determination of

hazardous properties and either used as daily cover or removed off site according to analytical

results.

Note that contaminated snow and ice must be disposed as contaminated or oily water.
