March 1995 Page iii Freshwater Intake End-of-Pipe FishDRAFT Screen Guideline The Department of Fisheries and Oceans (DFO) has prepared the Freshwater Intake End-of-Pipe Fish Screen Guideline to 1.0 assist proponents in the design and installation of fish screens |for the protection of anadromous and resident fish where freshwater is extracted from fish-bearing waters. This guideline Introduction will also assist regulatory agencies in the review of fish screen proposals.

A requirement for fish screening is stated under Section 30 of the Fisheries Act, where every water intake, ditch, channel, or canal in Canada constructed or adapted for conducting water from any Canadian fisheries waters must provide for a fish guard or a screen, covering, or netting over the entrance or intake so as to prevent the passage of fish into such water intake, ditch, channel or canal. Other sections of the Fisheries Act, or other Federal, Provincial, or Municipal Legislation and Policy may also apply to associated water extraction activities. Proponents are advised to contact the appropriate regulatory agencies regarding approvals or permits.

The objective of the guideline is to provide a National standard-of-practice and guidance for end-of-pipe fish screens at 2.0 freshwater intakes to prevent potential losses of fish due to entrainment or impingement. Entrainment occurs when a fish is drawn into a water intake and cannot escape. Impingement Guideline occurs when an entrapped fish is held in contact with the intake screen and is unable to free itself. The severity of the impact on Objective the fisheries resource and habitat depends on the abundance, distribution, size, swimming ability, and behaviour of the organisms in the vicinity of the intake, as well as, water velocity, flow and depth, intake design, screen mesh size, installation and construction procedures and other physical factors.

The Freshwater Intake End-of-Pipe Fish Screen Guideline deals exclusively with the sizing and design of fixed screens that are often placed at the end of a pipe used to extract water up to

0.125 m3/s, or 125 litres per second (L/s) (i.e., 2000 US gallons per minute (US gpm)). The guideline is intended for use in addressing fish screens for small permanent and temporary withdrawals for irrigation, construction, small municipal and

March 1995 Page 1 Freshwater Intake End-of-Pipe Fish Screen Guideline DRAFT private water supplies, etc. It is not intended for application to hydroelectric or canal screen designs; however, such proposals can be considered by regulatory agencies on a site-specific basis. The guideline focuses on the technical aspects of intake screens and the protection of fish rather than on policy, legislation, or environmental assessment processes and their application. This guideline has been developed to provide protection of freshwater fish with a minimum fork length of 25 mm (approximately 1 inch) since most eggs and fish larvae remain in bottom substrates until they reach the fry stage (i.e., 25 mm fork length). Other designs, in addition to intake screens, may be appropiate to address fish and fish habitat protection associated with water withdrawals. Such proposed designs should be addressed with the appropriate regulatory agencies on a site-specific basis.

Page 2 March 1995 Freshwater Intake End-of-Pipe FishDRAFT Screen Guideline Information that should be provided to facilitate evaluation of an end-of-pipe intake screen design intended for fish protection 3.0 during a freshwater withdrawal is highlighted below. Types of information requirements that may also be applicable to the water intake project as a whole are identified in Appendix A. Information • fish presence, species, and possible fish size or fish habitat Requirements conditions at the project site for Evaluation • rate or ranges of rates of withdrawal from the watercourse of Intake screen open and effective areas Screens • • physical screen open parameters with respect to the intake and the watercourse

• screen material, method of installation and supporting structures

• screen maintenance, cleaning, or other special requirements

The appropriate design of a fish screen is largely dependent upon the species and the size of fish requiring protection. 4.0 Appropriate installation and maintenance/cleaning of the screen are also important in keeping approach velocities low and ensuring satisfactory operation of the screen. For the purposes Design, of this guideline, emphasis is placed on the protection of freshwater fish with a minimum fork length of 25 mm from Installation, entrainment and impingement due to water extraction activities. & Maintenance Depending upon site-specific circumstances, a case may be made whereby the minimum fork length size of fish to be of Freshwater protected is greater than 25 mm. In this instance, the fish screen criteria for open screen area (Table 2 and Figure 1) and Intake End-of- screen mesh size (2.54 mm) presented here do not apply. Fish Pipe Fish screen criteria and guidance for the protection of fish larger than Sereens 25 mm is provided by Katopodis (1992). The following sections address the appropriate design of fixed freshwater intake end-of-pipe fish screens for the protection of fish with a minimum fork length of 25 mm. Guidance on

March 1995 Page 3 Freshwater Intake End-of-Pipe Fish Screen Guideline DRAFT installation, cleaning, and maintenance is provided. Common types of intake screens and associated intakes are also presented. Appendix B presents a sample calculation utilizing the guideline to determine the appropriate end-of-pipe intake screen size for the protection of freshwater fish.

4. 1 Fish Screen Criteria

To protect fish from impingement or entrainment, the approach velocity (i.e., the water velocity into, or perpendicular to, the face of an intake screen) should not exceed certain values based on the swimming mode (i.e., subcarangiform or anguilliform) of the fish present in the watercourse. The subcarangiform group includes fish that swim like a trout or salmon, and move through the water by undulating the posterior third to half of their bodies. The anguilliform group includes fish that swim like an eel, and move through the water by undulating most or all of their body. Table 1 presents the swimming modes of most common fish species in Canada. Contact DFO or provincial fisheries agencies regarding fish species that are not included in Table 1.

Envelope curves for approach velocities were developed for each swimming mode corresponding to a minimum fork length of 25 mm and a maximum endurance time of 10 minutes (the time the fish is in front of the face of the screen before it can elude it). To satisfy approach velocities of approximately 0.11 m/s and 0.038 m/s for the subcarangiform and anguilliform groups respectively, curves indicating the required open screen areas, based on fish swimming performance data, including fish species and size (Katopodis, 1990) and related to flows/extractions, were developed. Table 2 presents the required open screen area, in both metric and non-metric units, for end-of-pipe intake screens with a capacity up to 125 L/s (2000 US gpm). The open screen area is the area of all open spaces on the screen available for the free flow of water. The same information is presented graphically in Figure 1.

March 1995 Page 5 Freshwater Intake End-of-Pipe Fish Screen Guideline DRAFT 4.2 Design of Fixed End-of-Pipe Fish Screens

Once the required open area has been found from Table 2 or Figure 1, the effective screen area must be calculated. It is the area occupied by the open spaces (i.e., open screen area) and the screen material available for the free flow of water. The effective screen area should be provided at the intake location and is determined as follows:

Effective Screen Open Screen Area (Table 2) = Area (m2 or ft2) ( % Open Area (Table 3) ) 100

It should be noted that if the percent (%) open screen area is maximized, then the effective screen area required for a given flow is minimized. The narrowest dimension of any opening on the screen is referred to as the design opening, regardless of opening shape. The maximum design opening for a fish of 25 mm fork length is estimated at 2.54 mm (0.10 inches). Guidance on screen openings and materials is presented below.

• The screen openings may be round, square, rectangular, or any combination thereof, but should not have any protrusions that could injure fish.

• Screen materials may include brass, bronze, aluminum, monel metal, galvanized or stainless steel, and plastics. The screen material should be resistant to corrosion and UV light.

• Note: clogging due to corrosion is minimized with the use of stainless steel.

• Welded wedge wire screens offer reduced debris clogging and increased open area and screen stiffness, in comparison to round wire mesh and punch plate.

Table 3 presents several common types of screening material that meet the requirements of wire diameter, clear opening width and percent open area,

The dimensions of the fish screen can be calculated after the correct shape, configuration, location, and method of installation have been determined. This will usually be determined after a site investigation and a review of these guidelines. Included in Figure 2 are common screen shapes and the associated

March 1995 Page 7 Freshwater Intake End-of-Pipe Fish Screen Guideline DRAFT dimensions and area formulae. These are just examples of the many shapes and sizes in which fish screens can be fabricated. Screens are instream structures and, as such, should have sufficient strength and durability, and be capable of withstanding any potential large forces and impacts. Figure 3, 4, and 5 illustrate some of the various configurations, applications, and screen material types of end-of-pipe fish screens.

4.3 Installation

• Screens should be located in areas and depths of water with low concentrations of fish throughout the year.

• Screens should be located away from natural or man-made structures that may attract fish that are migrating, spawning, or in rearing habitat.

• The screen face should be oriented in the same direction as the flow.

• Ensure openings in the guides and seals are less than the opening criteria to make “fish tight”.

• Screens should be located a minimum of 300 mm (12 in.) above the bottom of the watercourse to prevent entrainment of sediment and aquatic organisms associated with the bottom area.

• Structural support should be provided to the screen panels to prevent sagging and collapse of the screen.

• Large cylindrical and box-type screens should have a manifold installed in them to ensure even water velocity distribution across the screen surface. The ends of the structure should be made out of solid materials and the end of the manifold capped.

• Heavier cages or trash racks can be fabricated out of bar or grating to protect the finer fish screen, especially where there is debris loading (woody material, leaves, algae mats, etc.). A 150 mm (6 in.) spacing between bars is typical.

Page 14 March 1995 Freshwater Intake End-of-Pipe FishDRAFT Screen Guideline 4.4 Cleaning and Maintenance

• Provision should be made for the removal, inspection, and cleaning of screens.

• Ensure regular maintenance and repair of cleaning apparatus, seals, and screens is carried out to prevent debris-fouling and impingement of fish.

• Pumps should be shut down when fish screens are removed for inspection and cleaning.

• Screens may be cleaned by methods such as air or water, backwashing, removal and pressure washing or scrubbing.

• Under certain site-specific winter conditions, it may be appropriate to remove screens to prevent screen damage.

• Flexible suction pipe may be used instead of solid, fixed piping for ease of screen removal and cleaning.

• Pump suction pressure can be measured to assess the need for screen cleaning.

To facilitate intake screen cleaning/maintenance, design and installation features such as orientation of the screen (e.g., in a cove) or variation in mesh shape (i.e., square wire/bars versus round wire/bars), etc. may be considered for regularly cleaned screens. For screens that will not be cleaned regularly, provision of considerably more open screen area (e.g., four times more) than determined from Table 2/Figure 1 may be considered. Such design/installation features should be addressed with the appropriate regulatory agencies on a site-specific basis.

Appendix C presents a list of units of conversion.

A proponent wishes to withdraw water at a rate of 0.075 m3/s Appendix B from a nearby pond. The pond supports populations of brown trout, brook trout, and American eel. The intake is proposed to Sample be cylindrical with the ends solid and #60 wedge wire screen Calculation around the cylinder.

What size must the intake screen be to satisfy the guideline requirements?

There are 4 steps to finding the answer:

1. Determine the fish swimming mode.

2. Determine the open screen area.

3. Determine the effective screen area.

4. Determine the dimensions necessary to produce the effective screen area.

1. Fish Swimming Mode

The fish swimming mode is found from Table 1. Brook trout and brown trout are listed as subcarangiform swimmers, while the American eel is an anguilliform swimmer.

2. Open Screen Area

Table 2 lists the required open screen area for both subcarangiform and anguilliform swimmers under flows up to 125 L/s (2000 US gpm). To use the table, if is necessary first to convert the flow from cubic metres per second to litres per second.

m3 0.075 x 1000 L = 75 L s 1 m3 s

For a flow of 75 L/s, Table 2 indicates that the open screen area must be:

• 0.69 m2 for subcarangiform swimmers, and

• 1.96 m2 for anguilliform swimmers.

The higher number (1.96 m2) is the more stringent requirement, therefore, it is used in the calculation of effective screen area,

March 1995 Page 23 Freshwater Intake End-of-Pipe Fish Screen Guideline DRAFT 3. Effective Screen Area

The screen material in this case is # 60 Wedge Wire. A review of Table 3 indicates that the % Open Area for this material is 63%, With this value and the previously determined area from Step 2, the following formula is used to determine the Effective Screen Area.

Effective Screen Area = Open Screen Area % Open Area ( 100 ) 2 = 1.96 m 63 ( 100 ) = 3.111 m2

4. Dimensions of Intake Screen

Figure 2 lists several common screen shapes and their respective area formulae. For a cylindrical screen where the ends are solid and screening is around the cylinder, the following formula applies:

Area = πDL The unknown dimensions are diameter (D) and length (L). These dimensions are determined by choosing a value for one and solving the equation for the other.

If the diameter is 0.600 m, then the length follows as:

Area = πDL

3.111 m2 = (0.600 m)L

3.111 m2 = (1.885 m)L

L = 3.111 m2 1.885 m L = 1.65 m

A 0.600 m diameter, 1.65 m long cylindrical screen would meet the design requirements. It should be noted that the dimensions given are representative of the screening area only; they do not include any screen that may be blocked by framing, etc. By comparison, if the pond only supported trout (subcarangiform), a 0.600 m diameter, 0.58 m long cylindrical screen would meet the design requirements.

APPENDIX G AIR QUALITY ASSESSMENT METHODS AND RESULTS

APPENDIX G

AIR QUALITY ASSESSMENT METHODS AND RESULTS

1 AIR QUALITY METHODS The operation of the Empress-Medicine Hat Crossover and Components 5A and 5B are not expected to be sources of air emissions; therefore, this assessment focuses on emissions that will be generated during the construction phases of the Project. Criteria Air Contaminant (CAC) and Greenhouse Gas (GHG) emissions were calculated based on the type of equipment and operating durations. During the construction phase, the construction equipment will produce CAC emissions including oxides of nitrogen (NOx), carbon monoxide (CO), fine particulate matter (PM2.5) and sulphur dioxide (SO2). Additionally, during the construction phase, the construction equipment will produce GHG emissions including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

The construction process for the Empress – Medicine Hat Crossover is estimated to take approximately 5 weeks (Table 2.4-2 of the Environmental and Socio-economic Assessment; ESA). The Component 5A and 5B construction process is estimated to take approximately 4 weeks (Table 2.4-3 of the ESA). Equipment used for onsite activities may include the following (Table G1):

• clearing/mowing activities: crawler tractors or tractor-pulled mowers • topsoil handling activities: crawler tractors, graders and backhoes • grading activities: graders, backhoes and crawler tractors • stringing and welding activities: pipe trucks, side-booms tractors, pick-up trucks, x-ray or ultrasonic inspection equipment mounted on pick-up trucks • trenching activities: backhoes • lowering-in activities: side-boom tractors • backfilling activities: backhoes, graders or crawler tractors • clean-up and reclamation activities: general machine clean-up

Construction emissions for the Projects were calculated using emission factors from AP 42 from the United States Environmental Protection Agency (U.S. EPA 2012) for construction equipment and generators. Total emissions from the construction phase were based on the type and operating durations of the construction equipment. No modelling was completed as construction emissions are emitted from intermittent sources and are short-term. A summary of estimated total emissions during the construction phase are presented in Tables G2 and G3.

2 GREENHOUSE GAS EMISSIONS METHODS

A desktop study was conducted on the Empress-Medicine Hat Crossover and Component 5 construction activities to identify the following:

• construction emissions from construction equipment were estimated using manufacturer’s specifications

• CO2, CH4 and N2O emissions were calculated based on British Columbia (B.C. MoE 2013) emission factors (Table G4)

The construction phases of the Projects will have an effect on GHG emissions to the atmosphere as a result of the use of heavy equipment and associated combustion of fuel (for the purpose of transporting work crews on- and offsite, clearing, soil movement, grading, welding, trenching, backfilling and clean-up).

The total CO2 equivalent (CO2e) for the project is 2,792 tonnes (Table G4). A comparison was made to Alberta and Canada baseline values by converting the Project’s total to mega tonnes of CO2e per year (Table G5).

(Environment Canada 2013a). The total CO2 equivalent (CO2e) for the Project is 2804 tonnes (Table G4). A comparison was made to Alberta and Canada baseline values by converting the Project’s total to mega tonnes of CO2e per year, and they were 0.0011% and 0.0003% respectively (Table G5).

2.2 Component 5A and 5B

Estimates of the GHG emissions are expressed as tonnes of CO2 equivalent (CO2e), which are calculated based on the global warming potential for each gas relative to the global warming potential of CO2 (Environment Canada 2013a). The total CO2 equivalent (CO2e) for the Project is 1376 tonnes (Table G4). A comparison was made to Alberta and Canada baseline values by converting the Project’s total to mega tonnes of CO2e per year, and they were 0.0006% and 0.0002% respectively (Table G5).
