Introduction to the guide

1. INTRODUCTION TO THE GUIDE

The Department of Fisheries and Oceans (DFO) has the responsibility to administer

the Fisheries Act which provides for the protection of fish and fish habitats. One of

the department’s responsibilities, in terms of fisheries management, is to protect fish

and fish habitat against activities that could alter or destroy them. To achieve this man-

date, DFO has elaborated a Fish Habitat Management policy with the ultimate goal to

obtain, at long term, a net gain of fish habitats. This department policy also includes

secondary objectives, among which the conservation of fish habitat with the guiding

principle of no net loss of the production capacity of habitats. The application

of this principle reflects DFO’s will to maintain the benefits that Canadians gain from

the productivity of fish habitats and fisheries resources, without competing with

economical development.

The application of the no net loss principle implies several steps, including the assess-

ment of potential impacts on fisheries resources of construction projects during their

planning stages. This guide should help managers and planners to control environ-

mental impacts and protect fish habitats.

1.1 Objective

The objective of this guide, prepared for DFO’s analysts, is to provide the department

with a standardized tool for the environmental assessment of bridge and road mainte-

nance, repair and demolition projects along shores and coastlines, with regards to the

application of the Fisheries Habitat Management Policy. The guide was designed to

facilitate project analysis by providing a systematic identification and evaluation of

elements of environmental concern, associated with a project proposal.

1.2 User’s manual

If used properly, this guide, proceeding by successive steps, will help the analyst in

identifying environmental stakes associated with a project, within the environmental

and social context of the receiving environment. The guide should also help the

1

analyst to select the most appropriate mitigation measures, with regards to the fore-

seen activities and to the sensitivity of fish populations and habitats. Finally, the guide

will help the analyst to prepare a support document in which will be presented all the

arguments supporting the decision and choices of the analyst concerning the admissi-

bility of the project and the corrections needed to meet the principle of no net

loss of the production capacity of the habitats. The exercise will provide the

department with a well documented case to support its position in an environmental

evaluation or at public hearings.

1.2.1 Structure of the guide

The guide is divided in four sections. Section 1 describes the analytical methodology

(Figure 1) for the project evaluation; section 2 presents a synoptic table (Table 2) that

allows the analyst to identify, upon reading the environmental impact assessment

submitted by the promoter, the potential impacts and the appropriate mitigation meas-

ures. Section 3 describes the criterias and the methodology used by the analyst to eval-

uate the significance of residual impacts after the application of mitigation

measures proposed by the promoter. Finally, section 4 includes the impact analysis

form where the analyst records his comments and the results of his analysis. This sec-

tion also includes the support document, which is comprised of three distinct forms.

The first form records the summary of the environmental analysis. At this point, the

analyst identifies the foreseeable significant impacts remaining after the application

of mitigation measures proposed by the promoter and of additional measures, when

necessary. In the summary, the analyst also determines the work surveillance and

monitoring program requirements and the public concerns. In the other two forms of

the support document, the analyst summarizes the elements of reflexion needed to

support DFO’s position by recording the arguments needed to justify the position.

The guide also comprises five appendices where the mitigation measures are detailed

(Appendices 1, 2 and 3), the pertinent laws and regulations are presented

(Appendice 4), a list of the regional DFO offices across Canada is given

(Appendice 5) and a glossary of the principal terms used in the guide is provided

(Appendice 6).

1.2.2 Analytical procedure

Figure 1 presents the progression, step by step, that the analyst must follow to conduct

the environmental assessment of a project. First, the analyst consults simultaneously

section 2 of the guide (potential impacts and mitigation measures) and the impact

study supplied by the promoter. At the same occasion, he uses section 3 of the guide

to proceed with an evaluation of the significance of residual impacts and fills in the

impact analysis form of section 4. At this stage of the evaluation, the analyst should

consult the promoter to obtain additional information or to suggest modifications to

the project. Then the analyst fills in the three forms of the support document of

section 4.

The forms should be completed as meticulously as possible since they are an integral

part of the file. Besides standardizing the project evaluation procedure, duly filled

forms will constitute a structured database accessible at all times to everyone for

future project evaluation.

1.2.3 Terminology

In order to accurately delimit the reach of this guide, the following section defines a

few key terms.

Fish

Article 2 of the Fisheries Act defines fish as all life stages (eggs, milt, sperm, spawn,

larvae, fries, juveniles and adults) of fish, molluscs, crustaceans and marine animals.

Fish habitat

Article 34(1) of the Fisheries Act defines fish habitat as spawning sites, rearing areas,

growth and feeding areas, and migration routes, on which the survival of fish is direct-

ly or indirectly dependant.

FIGURE 1. Procedure for an environmental assessment

Maintenance

Bridge or road maintenance comprises all the activities conducted on a regular basis

to maintain the efficient functioning of a structure.

Repair

Bridge and road repairs include all small and medium scale operations conducted to

increase the efficiency or lifespan of a structure.

Demolition

Eliminating, totally or in part, a bridge or a road.

Source of impact

Component of a project or of a construction, exploitation or maintenance operation

that could have an impact on the environment.

Environmental impact

Any effect that can be qualified or measured of an action producing a modification on

the biophysical or social environment.

Residual impact

Foreseen environmental impact which persists after the application of mitigation

measures. Its importance remains an approximate evaluation since, in most cases, its

actual effects are unknown.

Section 2.

Impacts and mitigation measures

2. IMPACTS AND MITIGATION MEASURES

The objectives of this section of the guide are to identify the impacts caused by bridge

and road maintenance, repair and demolition projects and to select appropriate miti-

gation measures. This section is essentially comprised of two tables. Table 1 lists, in

order of appearance, the various activities which are probable sources of impacts.

Table 2 presents the potential impacts of these activities on fish and fish habitat. The

nature of the impacts presented in that table corresponds to the strongest effect

expected from a given activity. The analyst will also find in table 2 the necessary ele-

ments of information to identify and assess adequately the real impacts of each activ-

ity. Finally, table 2 presents, with a reference code, the various mitigation measures

applicable; these are described in detail in appendice 1. In addition the analyst will

find, in appendice 2, a series of diagrams and tables illustrating certain mitigation

measures.

As a complement of information, the analyst will also find in appendice 3 a

cost/efficiency evaluation of various erosion and sedimentation control measures, and

in appendice 4 a presentation of some articles of federal and provincial laws and

regulations, susceptible to be applied in order to maximize fish and fish habitat

protection during work operations.

Section 3.

Significance of residual impacts

3. SIGNIFICANCE OF RESIDUAL IMPACTS

The evaluation of the significance of the impacts attributable to the various activities

of the project under study also applies to the residual impacts, after the implementa-

tion of mitigation measures proposed by the promoter. This procedure allows the ana-

lyst to evaluate, with the assistance of other experts if needed, the real environmental

issues associated with the project, as proposed by the promoter, and to make an

enlighten decision concerning the acceptability of the project with regards to protec-

tion of fish and fish habitats. The following section presents the approach proposed

for the evaluation of residual impacts.

3.1 Analytical procedure

As shown in figure 2, the evaluation of the significance of an impact proceeds with

several steps and is the result of the interaction between the intensity of the distur-

bance, its duration and its extent. First, the analyst must list the activities having an

impact and determine the environmental components likely to be affected by the

project, including fish and fish habitats (Step 1). Using various assessment

parameters, the analyst must determine the environmental value and the level of dis-

turbance of each component (Step 2). Then, the analyst proceeds to an evaluation of

the intensity of disturbance for each component (Table 3) and determines the duration

and extent of the impacts of each intervention (Step 3). Afterwards, the

analyst evaluates, with the use of the evaluation grid, (Figure 3), the significance of

each residual impact (Step 4). Finally the results of the analysis are compiled in the

impact assessment summary grid (Table 4) (Step 5). At the end of this procedure, the

analyst must determine which components are affected by the project and to which

extent, and for which components there remains an uncertainty as to the nature and the

significance of the impacts. This final step will allow the analyst to fill the

impact assessment form and support documents (Section 4).

30

FIGURE 2. Analytical procedure for the evaluation of the significance of impacts

3.2 Assessment parameters

The relative importance of the environmental consequences of the modification of an

element, considering the level of disturbance (extent of structural and functional

changes) of an element and the environmental value of the element, is expressed as

the intensity of the impact. Thus, the more environmental value is attributed to an ele-

ment on the basis of its particularities, the greater the environmental impacts of its

alteration will be. Therefore the intensity is a major dimension of the impact, although

its relative importance is always counterbalanced by the duration and extent of its

effects.

Environmental value

The environmental value of a component (species or habitat) is the expression of its

relative importance within the environmental and social context where the project is

conducted. Its evaluation is based, on the one hand, on the intrinsic value of the com-

ponent, as defined by its function, its representativeness, its degree of utilization, its

diversity and its rarity or its unicity, and on the other hand, on its social value,

reflecting the popular, legal and political importance of this component. The social

value assesses the popular or political will to preserve the integrity or the particulari-

ties of an environmental component. It is expressed through public concern or

through rules and regulations. Thus any interventions to protect or enhance the

original character of a component will contribute to raise its environmental value.

Function: This parameter assesses, at the biological level, the degree

at which the physical and biological components of a given

environment are useful or essential to certain biological

activities such as reproduction, feeding, migration, rearing,

etc. which are all essential to the survival of fish

communities. At the human level, the function parameter

could evaluate, for example, the importance of a species of

fish for recreational, tourist or commercial activities.

32

Representativeness: This parameter is the expression of the typical nature of a

component that must be protected because of its biological,

social or heritage value. For example, the St. Lawrence

beluga population at the mouth of the Saguenay is

representative of an isolated population reproducing, feed-

ing and growing in the river estuary, with little or no con-

tacts with northern populations.

Degree of utilization: This parameter represents the level and frequency of

utilization of an environmental component by fish or by

humans. It may be expressed as the density (varying

proportion of a population) or as the frequency of

occupation. Thus, a specific environment (river, lake,

section of river, etc) may be the reproduction or feeding site

for the majority of the population of a species of fish or

mammal. The utilization of a site may be permanent,

occasional, regular, cyclic, seasonal, etc.

Diversity: Diversity represents the nature of a component or of a

specific environment with several simultaneous or

successive aspects (for example, several species of fish,

different habitats and ecological niches, different uses).

This parameter is an indication of the importance or the

quality of a component or a specific environment.

Rarity or unicity: This parameter is a major discriminant index of the

importance of an element; it refers to the exceptional or

extraordinary nature of an environmental component, or to

the fact that a species or a particular habitat is threatened or

endangered.

33

The four classes adopted to assess the environmental value of a component are:

very high, high, moderate, low. Because of the wide range of parameters used by

experts in very specialized fields, and of the great variability of these parameters

according to each different situation, the experts will have to make a selection on

the basis of their expertise and judgement.

Level of disturbance

The level of disturbance evaluates the extent of the alterations affecting the struc-

tural and functional characteristics of a component in a given environment. These

changes may induce the total or partial destruction of one or more characteristics

specific to the component. The level of disturbance implies the notion of

vulnerability of the component, which translates by the adaptation capacity (toler-

ance) of the communities and their habitat to disturbance and by the minimal func-

tional area below which a system cannot function adequately and thus looses its

integrity. The level of disturbance also includes a spatial dimension, expressed as

the proportion of the component affected by the project. Thus, the more vulnerable

or the less tolerant a community is and the larger the proportion affected, then the

higher the level of disturbance.

Three levels of disturbance are used to qualify the extent of disturbances:

• strong: When the impact induces the loss or a modification of all the

characteristics of the component, greatly affecting its quality and

threatening its integrity;

• moderate: When the impact reduces slightly the quality of the component,

affecting lightly its integrity and its utilization;

• weak: When the impact modifies only very lightly the quality of the

component, not affecting in any perceptible way its integrity or

utilization.

34

3.2.1 Assessin the intensity

The classes of intensity of the impact, which vary from very strong to weak, are the

results of the interaction between the environmental value and the level of disturbance

of the environmental component. The following table presents the assessment grid for

the intensity of an impact.

TABLE 3. Assessment abacus of the intensity of an impact

LEVEL OF ENVIRONMENTAL VALUE

DISTURBANCE Very high High Moderate Low

Strong Very strong Strong Moderate Weak

Moderate Strong Strong Moderate Weak

Weak Moderate Moderate Weak Weak

3.2.2 Assessment of extent

The extent of an impact corresponds to the carrying_distance of the effects generated

by an intervention made in a given environment. The extent is qualified as follows:

• regional extent: if the impact is felt beyond the study area (e.g. a river basin);

• local extent: if the impact is felt over the whole study area;

• punctual extent: if the impact is limited to the immediate vicinity of the project.

3.2.3 Assessment of duration

The duration of an impact refers to the period during which the effects of an inter-

vention are felt. The duration of an impact should not be confused with the duration

of the source of impact. In fact, an intervention conducted over a few weeks could

have impacts on certain components of the environment over several years.

35

Thus, the duration of an impact should refer to the period needed for recuperation or

adaption of the components impacted upon. Impacts are of long, moderate or short

duration.

• long duration: impact of which the effects are felt continuously for the

life-span of the project and beyond. They may even be

irreversible.

• moderate duration: impact of which the effects are felt continuously, but over a

period shorter than the duration of the project.

• short duration: impact of which the effects are felt at a given moment in

time and last for a period of time shorter than the duration

of the project.

3.3 Significance of the impacts

An integrating index, allowing a global evaluation of a potential impact on a given

component, is used to determine the significance of an impact. It should be remem-

bered that the significance of an impact is assessed by combining an index of the

intensity, which integrates the environmental value of a component and its level

of disturbance, and two indexes characterizing the extent and the duration of the

impact.

The correlation established between each of the indexes (intensity, extent and dura-

tion), as shown in figure 3, is used to determine the level of significance of a residual

impact. There are four levels of significance:

• major impact;

• moderate impact;

• minor impact;

• minor to no impact.

36

Generally, an impact is considered major when it modifies deeply the nature and the

utilization. of an environmental component which is either very vulnerable or hardly

tolerant, along with having a high value. The significance of an impact decreases

(moderate, minor or nil) along with the vulnerability and the value of the component

affected.

Once the significance of an impact has been determined for a given activity and a

given environmental component, the analyst compiles the result in the impact

assessment grid (Table 4). After all the activities have been analyzed and the assess-

ment grid completed, the analyst will have a global view of the sources of impact, of

the significance of each of the impacts and of the environmental components

affected. This information can then be used to fill the impact assessment form,

presented in section 4.

APPENDICE 2

Diagrams of various mitigation measures

APPENDICE 2.6 Protection measures as a function of the type of work site and the extent of projects (from Department of Transports, 1992 a).

EXTENT OF PROJECTTYPE OF

WORK SITE Small Medium Large(less than 500 m2) (500-10 000 mZ) (more than 10 000 m2)

Natural Partial confinement Total confinement Total confinement andand recycling enclosure* and recycling enclosure recycling enclosure

Agricultural Total confinement and Total confinement and Total enclosure withrecycling enclosure recycling enclosure negative pressure

Urbanized Total confinement and Total enclosure with Total enclosure withrecycling enclosure negative pressure negative pressure

• Partial enclosures can also be used for touch-up paint jobs. However, they are not accepted in the vicinity of sensitive biophysical environments or freshwater intakes or when the water bodies are used extensively(recreation purposes or other).

APPENDICE 2.10 List of technical, economical and environmental factors to be consideredwhen selecting dredging and transportation equipments (from Centre Saint-Laurent, 1992).

CONSIDERAIIONS FACTORS

Technical • volume to be dredged;• history of past-dredging at site and in. the vicinity (frequency, volumes, etc.);• particle size;• dredging-site in relation with proposed disposal site;• surface area, form and depth of dredging-site (the ferrying and operation of an

oversized dredge could induce an increased recirculation of dredged material);• the precision required (horizontal and vertical);• the presence of obstacles interfering with the circulation or the operation of the

dredge (bridges, shoals, breakwater, uneasy access);• possible conflicts with commercial shipping and yachting;• material consistency (cohesion, density, compactness), presence of debris;• wind, wave, swell, tide and current conditions at dredging and disposal sites and

within ferrying route;• site and area available to install sediment catch basins;• constraints related to transportation (presence of wharves, land relief and

associated constraints, distances);• the need to establish alternate dump sites in the transport corridor;• if needed, the type of proposed pre-treatment of treatment;• the distance from dredging site to disposal site;• compatibility with disposal and (or) treatment operations;• quality and formation requirements for acting personnel;• requirements concerning manoeuvrability, draught, access or productivity;• regulatory requirements or legal constraints relating to materials, sites or

techniques.

Economical • exploitation unit costs for each type of equipment;• availability of equipments;• time constraints;• transportation and disposal costs;• effects on disposal and (or) treatment costs;• regulatory requirements or legal constraints relating to materials, sites or

techniques.

Environmental • the nature and level of contamination of dredged sediments and the physical,chemical and toxicological characteristics of contaminants;

• the “environmental behaviour” of materials and contaminants (mobility, reaction toleaching, toxicity, bio-accumulation potential, etc.);

• presence and proximity of sensitive parameters (water intakes, wells, recreationalor commercial activities);

• presence and proximity of sensitive natural parameters (reproduction, rearing orfeeding sites of aquatic, avian or terrestrial fauna);

• the presence of contaminants or of pollution sources in the area;• regulatory requirements or legal constraints relating to materials, sites or

techniques;• health and safety requirements for acting personnel.

APPENDICE 2.12 Culvert designs and characteritics (adapted from Department of Transports, 1992c).

Type of culvert Characteristics

• Retains natural stream substrate and water velocities;

• If properly installed, does not hinder fish passage.

• Natural stream width near bottom; water back-upis more intense than in round or elleptic culvert;

• Box culverts can be put side by side to maximigewater velocities;

• Baffes are easy to design and install;• Limits fish passage during low flow due to

decreased flow depths.

• Natural stream width near bottom; water back-upis more intense than in round or elliptic culverts;

• Wide, flat profile is an advantage for low clear-ance installations or when upstream incresses inflow depth must be minimiged;

• Can be designed to retain some stream substrate.

• Represents a compromise between round culvertand pipe arch cross-sections and an additionnaloption for designess;

• Stream substrate in hardly retained in culvert.

• Concentrates water during low flow;• Whenever possible, avoid use where fish

migration is important;• High turbulence hinders fish passage; Baffles are

difficult to install;• Generally restricts stream width.

APPENDICE 2.25 Guidelines for the excavation of a temporary diversion channel (from Department of Transports, 1992c).

Steps Description

1 Dig the temporary diversion channel while leaving extremities “A” and “B” closed.

2 Gradually remove the upstream dyke “A” and let sediments deposit for 48 hours(the time can be reduced to 24 hours if all sediments have deposited).

3 Remove the downstream dyke “B”.

4 Install dyke “D” upstream of river section to be dried.

5 After drainage, install the downstream dyke “C”.

6 Construct new structure (culvert of bridge).

7 Gradually remove the upstream dyke “D” and let sediments deposit for 48 hours(the time can be reduced to 24 hours if all. sediments have deposited).

8 Remove the downstream dyke “C”.

9 Refill the diversion channel beginning in the upstream portion.

10 Proceed with shore stabilization along the natural stream and revegetation ofdiversion channel.

APPENDICE 2.26 Guidelines for the digging of a new permanent river bed (from Department of Transports, 1992c).

Steps Description

1 Dig new permanent channel while leaving extrimities “A” and “B” closed.

2 Gradually remove the upstream dyke “A” and let sediments deposit for 48 hours(the time can be reduced to 24 hours if all sediments have deposited).

3 Remove the downstream dyke “B”.

4 Install dyke “D” above the old river bed section.

Dissipation basin Natural or artificial basin in which the energy of a breaking wave or of a high-speed jet is dissipated.

DitchOpen trench for run-off water.

DiversionRedirect a part or the totality of a stream flow outside the natural stream bed.

DiversityCharacteristic of a component which includes many different aspects either simultaneously or successively. Diversity is usually linked to the complexity and heterogeneousness of an element, a community, a biotope or an ecosystem.

Duration of impact Relative temporal value expressing the period of time during which the impacts of an intervention are felt by the environmental element affected.

APPENDICE 6 Glossary (cont’d 2)

EcosystemA functional unit limited in space, defined not only on a territorial level by its structure but mostly by itsfunctioning.

Ecotone Transition between two different neighbouring ecosystems where an increase of exchanges between twoenvironments (edge effect) is felt, attracting several plant and animal species. E.g. The shoreline being thetransition between terrestrial and aquatic systems.

EmbankmentRoad-slope between road shoulder and road ditch.

Environment The natural and cultural conditions that can effect living organisms and human activities or, according tothe terms of the “Loi sur la qualité de l’environnement (L.R.Q., ch., Q-2, Art.1); water, air and soil or anycombination of these, or the ambient environment with which living species have dynamic relationships.

Environmental component Expression designating any environmental entity which, depending on the scale and context, could be a ter-ritorial unit or an element of the environment.

Environmental valueCriteria of the level of resistance and the significance of the impact expressing the importance of a territori-al unit or of an element in its environment.

Erosion Action of wear and transformation of the earth’s crust induced by natural agents (water, wind, frost, etc)and human activities (agriculture, urbanization, deforestation, etc.).

Expansion joint Device set between two elements of a structure to allow for temperature induced motion (contraction andexpansion).

Extent of an impact Surface area affected by an environmental impact. It can express either a relative surface or a relative dis-tance from the source of impact.

FillMaterial used to build up the roadbed, obtained from excavations, ditches or borrow pits.

APPENDICE 6 Glossary (cont’d 3)

Flood rise Short duration rise of the water level above normal conditions caused by heavy rainfalls or snowmelt.

FlowThe river flow is measured as the volume of water flowing during a given period of time through a cross-section of the river and is given as volume units/time units: L/s, m’/day, m’/year. The volume is obtained bymultiplying the surface of the cross-section by the mean current velocity.

FunctionIndex of interest designating the specific activities of an environmental component within an ecosystem.Generally, the more essential and useful a function is for the development of a community, the greater theinterest and the environmental value.

Gabions Compartmented rectangular containers made of thickly galvanized steel wire-mesh with a removable top.Filled with stones, gabions are used to stabilize shores and stream beds.

Gravel Granular material used for roadbeds.

Level of perturbation Index of the intensity of an impact expressing the extent of the modifications to structural and functionalcharacteristics of the element affected by the project and inducing a deterioration of its initial condition.

APPENDICE 6 Glossary (cont’d 4)

Level of resistance Relative value given to a territorial unit expressing its degree of opposition or incompatibility with the proj-ect. A unit is considered resistant when it constitutes an obstacle, more or less important, to the projectimplementation because of its environmental value -and its vulnerability.

Low-waterPeriodical drop of water level. Lowest level observed in a stream in the course of a season or a year.
