1. INTRODUCTION
The Comox Valley Regional District (CVRD) is proposing to expand the Bates Road parking area of Seal Bay
Nature Park (the Project). The expansion proposes to increase the parking capacity from approximately
30 stalls to 71 stalls as well as improve safety for traffic and pedestrians along Bates Road. Note that a
revised drawing was provided in June of 2021, this Environmental Management Plan (EMP) has been
updated to reflect these recent design changes. Note that EMPs should be treated as “living documents”
and may be updated as the project progresses to incorporate new information or design changes.
This Environmental Management Plan (EMP) describes the environmental performance standards and
responsibilities of all contractors in executing this Project.
2. PROJECT DESCRIPTION
The existing gravel parking lot on the east side of Bates Road will be expanded eastwards and designed
for improved safety (Figure 1). The expansion will be a one-way drive-through loop that has been routed
to retain the large veteran Douglas-fir (Pseudotsuga menziesii) trees along the edge of the existing parking
area and minimize clearing of other mature trees to the extent possible. A vegetation island in the center
of the loop will be retained and includes some large trees.
The Project will require approximately 17,000 m2 of clearing and grubbing to accommodate the new
parking area and drive-through access and will require some clearing of mature mixed forest. The new
parking area will be topped with gravel. At least two culverts will be installed under the east side of the
loop to maintain natural hydrology and ensure water does not impound in the vegetated center area. The
area is relatively level and drains eastwards. The project has been designed to utilize the existing parking
area as well as natural gaps in the mature forest.
Over the course of discussions on site, it has been advised that one or more footpaths be placed through
the vegetated island and that large woody debris from the site be positioned to deter pedestrian traffic
through the remainder of the vegetated area.
There are no watercourses or wetlands within the Project; however, there are areas where surface pooling
is relatively common.
3. REGULATORY SETTING
Seal Bay Nature Park is a regional park administered by the CVRD. The BC Ministry of Transportation must
approve the parking area design for safety considerations and compliance with provincial and federal
regulation. Other environmental acts and regulations potentially relevant to the project include:
BC Wildlife Act (Ministry of Forests, Lands and Natural Resource Operations);
BC Park (Regional) Act (Ministry of Forests, Lands and Natural Resource Operations);
BC Environmental Management Act (Ministry of Environment);
BC Heritage Conservation Act (Ministry of Forests, Lands and Natural Resource Operations);
BC Wildfire Act (Ministry of Forests, Lands and Natural Resource Operations);
Canada Migratory Bird Convention Act (Environment and Climate Change Canada);
Canada Species at Risk Act (Environment and Climate Change Canada); and,
Local Government Act and applicable bylaws.

4. BIOPHYSICAL OVERVIEW
A biophysical overview assessment was conducted in order to inform this EMP. Note that First Nation
engagement and assessment for archaeological or cultural resources were not included in the scope of
this report. It is understood that an archaeological assessment in support of this project was completed
by Jesse Morin at the direction of the CVRD. No cultural materials were identified on site during the course
of that assessment (Pers. Comm. B. Allaert 2020). The Environmental Protection Plan (EPP) provided in
Section 6.0 includes general standards and procedures related to protecting archaeological resources.
4.1. Methods
4.1.1. Desktop Review
For the purposes of focusing this assessment, the Project Area was defined as the boundaries of the
proposed development with an approximately 30 m buffer applied.
An initial list of species of conservation concern and legally-designated species that potentially occur in
the Project Area were gathered from BC Conservation Data Center (CDC) Species and Ecosystems Explorer
online application (2021) based on the following search criteria:
Animals OR Plants OR Ecosystem Realm-Groups: Mixed Forest; AND Regional Districts: Comox
Valley; AND occurring within the CWH Biogeoclimatic Zone
Once this initial list was compiled, the following information sources were reviewed for occurrence
records and habitat information:
iMapBC (DataBC, 2020);
Comox Valley Regional District iMap (CVRD 2020);
Invasive Alien Plant Program (IAPP 2020);
E-Fauna (Klinkenberg, 2019);
BC Species Summaries (BC CDC 2020); and
Committee on the Status of Endangered Wildlife in Canada (COSEWIC) reports.
The probability of wildlife species of management concern occurring within the Project Area was assessed
using the area-specific species lists compiled from the BC CDC, species information, available federal
recovery strategies, Species at Risk Act (SARA) Schedule 1 range maps, Committee on the Status of
Endangered Wildlife in Canada (COSEWIC) Status Reports, and previous professional experience in the
region. The known distribution and habitat requisites of each species was reviewed and the probability of
the species occurrence within the Project Area was assessed based on the mobility of the species, the
proximity of known occurrences, and by comparing habitat requisites of individual species with the habitat
suitability of the Project Area. Each listed species was then assigned a low, moderate, or high probability
of occurrence, based on the following definitions:
Low probability: those species whose known range does not correspond to the Project Area and/or
those species whose habitat requisites are absent from the Project Area (e.g., grassland, estuary,
tundra);
Seal Bay: EMP July 21, 2021
3 | P a g e
Moderate probability: those species whose range and habitat requisites are present in the Project
Area but are not known within 5 km of the Project Area (based on the BC CDC [2016b] and
professional knowledge of the Project Area); and
High probability: those species whose range and habitat requisites are present in the Project Area
and are known to the general area surrounding the Project Area.
Invertebrates in the query results were not assessed. Assessment of vegetation was limited to a desktop
search of known occurrence records and an assessment of the Project Area’s likelihood to support rare
plants. Due to the season of the field assessment, species-specific surveys were not appropriate and
incidental observations of rare species were unlikely.
Ecosystems at risk were assessed in the field based on the species assemblages and biophysical
descriptions provided.
The BC Invasive Alien Plan Program (IAPP, 2020) was queried for known records of invasive species that
may occur in or around the Project Area. The complete query results are provided in Appendix A.
4.1.2. Field Assessment
A site reconnaissance was conducted by Kim Poupard, R.P.Bio. (Calidris Ecological Services Ltd.) on
December 31, 2021. This included a site walk and discussion with Brian Allaert of the CVRD and Ryan
Murphy, consulting arborist, to review the project design and provide input into the plan.
A second site visit occurred on January 21, 2021 with Mr. Poupard, Mr. Allaert and Mike Hanson, P.Eng of
Onsite Engineering Ltd. to review recommendations made during the previous assessment and provide
input into the final design.
During the field reconnaissance, specific attention was paid to potential occurrences of the following:
Habitats likely to support species at risk (e.g., wetlands, riparian, old growth forest);
Ecosystems at risk;
Species at risk;
Invasive plants;
Wildlife habitat features (e.g., wildlife trees, stick nests, dens and burrows);
Important wildlife habitat (.g., wetlands, riparian, old growth forest);
Watercourses; and,
Potential adverse environmental interactions from the proposed Project.
A general description of the vegetation communities within the Project Area was compiled. Note that the
field reconnaissance was limited to visual observations of land cover types and chance encounters; no
species-specific inventories were conducted. Note that the timing of the assessment was outside of the
appropriate season for compiling comprehensive vegetation lists.
A geo-referenced PDF on a handheld GPS enabled device was used to navigate the site and georeference
important features. Observations were recorded with photographs and field notes.
A professional arborist (Mr. Murphy) was retained to conduct a detailed assessment of the trees
implicated in the project and inform this EMP. The arborist report is provided in Appendix B.

4.2. Results
4.2.1. Environmental Setting
The project is located within the Coastal Western Hemlock Very Dry Maritime (CWHxm1) biogeoclimatic
zone (iMapBC 2021). The area is dominated by mature mixed forest dominated by coastal Douglas-fir
(Pseudotsuga menziesii) with a lesser component of grand fir (Abies grandis), western redcedar (Thuja
plicata) and bigleaf maple (Acer macrophyllum) in the canopy. The understory is dominated by sword fern
(Polystichum munitum), regenerating western redcedar, western hemlock (Tsuga heterophylla) and grand
fir in the shrub layer. Scattered red alder (Alnus rubra) and black cottonwood (Populus trichocarpa) are
also present. Other common understory species include Salal (Gaultheria shallon), dull Oregon grape
(Berberis nervosa), red huckleberry (Vaccinium parvifolium), salmonberry (Rubus spectabilis), trailing
blackberry (Rubus ursinus) and bracken fern (Pteridium aquilinum).
The site is slightly wetter than zonal within the CWHxm1, with rich soil (site series 04 Fd – Swordfern). The
site has been modified by historical forest harvesting.
A review of the Invasive Alien Plant Program (IAPP) online map for known occurrences of invasive species
resulted in the identification of eight species in the vicinity of the project including four that are listed as
‘noxious’ under Schedule A of the Weed Control Act Regulation. These are mostly located along the park
boundaries with the exception of Himalayan blackberry (Rubus armeniacus) which has been recorded
within the park. A list of these occurrences is provided in Table 1. Note that none of these were noted on
the project site during the field visits. Yellow archangel (Lamium galeobdolon), a nuisance weedy species
was detected on the site, however. Mitigation to avoid further encroachment of this species has been
provided.

4.2.2. Species at Risk
The BC Conservation Data Center (CDC) online mapping tool was queried for marked known occurrence
records of species at risk in the vicinity of the Project. None are shown within 1 km of the project. The
nearest occurrence record is approximately 1.2 km west of the Project. This record is a red-listed
ecological community: Trembling Aspen - Pacific Crab Apple / Slough Sedge (Populus tremuloides - Malus
fusca / Carex). This is described as a deciduous wetland within Seal Bay Park occupying approximately 9.4
Ha (BC CDC 2014a). No interaction with the project is anticipated.
The next nearest occurrence record is the provincially blue-listed yellow sand-verbena (Abronia latifolia)
along the foreshore at Little River approximately 4.4 km southeast of the Project. There is no habitat for
this species in the Project area and no interaction is anticipated.
There are records of Western Screech-owl (Megascopes kennicotti kennicottii) approximately 6.7 km
west-northwest of the Project. This species is provincially blue-listed and also listed as Threatened on
Schedule 1 of the federal Species at Risk Act. Habitat for this species may be present in and around the
Project Area. Work should be conducted outside of the breeding season for this species (late January
through May; Cannings et al 2020). If clearing during this period is unavoidable, a pre-clearing survey
should be conducted.
Other wildlife species with a ‘moderate’ or ‘high’ likelihood of occurrence within the Project Area based
on the criteria above and previous professional knowledge of the region, are provided in Table 2.

There is no suitable breeding habitat for northern red-legged frog (Rana aurora) or western toad
(Anaxyrus boreas) in the Project Area. However, these species may also inhabit upland forest areas
outside of the breeding season and may be present in the Project Area.
Evening Grosbeak (Coccothraustes vespertinus) use a range of habitat types including coniferous and
mixed forest as well as riparian areas (BC CDC 1995). They are year-round residents in the region and may
occur in the project area.
Great Blue Heron (Ardea herodias fannini) may use large trees for nesting though none were noted during
the field assessment. Nests are usually conspicuous and relatively easy to detect, particularly if active.
There is no forage habitat for this species within the project area.
The Laingi subspecies of Northern Goshawk (Accipiter gentilis laingi) are associated with mature and old
growth forest. On Vancouver Island home ranges tend to be donated by Douglas-fir and western hemlock
with good canopy closure (BC CDC 2005). There is suitable habitat for this species within the Project Area;
however, the relatively small size of the forest and patchy nature are likely limiting for this species.
The habitat within the Project Area is suitable for Band-tailed Pigeon (Patagioenas fasciata). Attention
for the presence of these birds will be required during pre-clearing sweeps and/or breeding bird surveys.
Western Screech-owls (Megascops kennicotti) are generally associated with large diameter mixed forest
near water and commonly use riparian areas (Cannings et. al. 2020). For nesting, they require large
woodpecker tree cavities such as those commonly excavated by Northern Flicker or Pileated Woodpecker
(Cannings et. al. 2020). Habitat for this species may be present in and around the Project area. Work
should be conducted outside of the breeding season for this species (late January through May; Cannings
et al 2020). If clearing during this period is unavoidable, these should be identified during a pre-clearing
breeding bird surveys.
Little brown myotis use a wide range of habitat types including man-made structures as well as caves and
hollow trees (BC CDC 2015). Winter hibernation sites are more typically caves, tunnels, or other similar
sites with stable temperatures between 2 and 12°C (BC CDC 2015). Suitable trees to support this species
were not detected within the Project Area.
Townsend’s big-eared bat in the region tend to use forested areas as well as buildings in areas with a
matrix of woodlands, grasslands, and shrub-dominated habitats (BC CDC 2014b). They are a non-migratory
species that move moderate distances between summer foraging, breeding areas and winter hibernacula.
Overwintering and maternity colonies typically use caves and mine tunnels with buildings being used more
often for maternity roosts (BC CDC 2014b). The Project Area has limited potential habitat for this species
and overwintering is not expected.
The two large mammal species included in the list, Roosevelt elk (Cervus elaphus roosevelti) and
Vancouver Island wolverine (Gulo gulo vancouverensis), are highly mobile species with large ranges.
Though these species may travel in or around the Project Area on occasion, it is not expected to be an
important part of their habitat.
The Project Area contains suitable breeding habitat for migratory birds. The Migratory Bird Convention
Act prohibits harm to migratory birds or disturbance to their nests or eggs. The Project Area is within
nesting zone A1 which has a nesting period of March 26 to August 9 (Environment Canada 2020). Tree
Seal Bay: EMP July 21, 2021

and vegetation clearing should be avoided during this period. If it is unavoidable, a pre-clearing nesting
bird survey should be conducted by a qualified professional to assess compliance with the Migratory Bird
Convention Act.
4.2.3. Fish and Aquatic Habitat
There is no fish or aquatic habitat within the Project Area. The nearest stream is to the south and east of
the project and is greater than 30 m away (Figure 1). This stream (watershed code: 920-580900) channel
is deeply incised and appears to be prone to erosion. Recent slumps were noted along the banks just east
of the project.
According the provincial Habitatwizard database (2021), the stream is not fish-bearing. There is a portion
of the riparian area of this watercourse east of the project that has been identified in the regional Sensitive
Ecosystem Inventory (SEI, CVRD iMap 2021). No interaction with this habitat is anticipated as a result of
the project.
5. HIGH RISK ACTIVITIES
For the purpose of this EMP, the project activities that have a High-risk of adversely affecting
environmental resources include:
Activity Risk
Vegetation Clearing Interaction with species at risk, breeding birds and damage to tree roots.
Clearing may also have long-term impacts to trees retained along the edge.
Clearing may require the use of spark-inducing tools that may have an
associated fire hazard.
Soil Excavation Erosion, soil degradation, introduction of exotic species.
Mr. Murphy estimated that a total of 38 trees will require falling to accommodate the new parking area
(Appendix C: Table 1), the largest of which is 100 cm diameter-breast-height (DBH) and an estimated
height of 42 m. An additional ten trees were assessed as danger trees outside of the Project footprint (see
Appendix B of the Arborist’s Report). Treatment of the danger trees will be at the discretion of the CVRD
and the Contractor. Note that Mr. Murphy has been provisioned some field time in order to provide
recommendations for tree modifications to the contractor directly.
The retention and protection of veteran trees has been considered in the Project design. However, there
is considerable uncertainty regarding the long-term resiliency of trees retained along the edge of the
project as a result of root damage and changes in soil conditions, hydrology, and canopy structure. Note
that visible symptoms of stress may take some time to express. Annual monitoring of tree health over the
next five years is recommended to identify and address potential tree health issues.
Risks associated with soil excavation should be mitigatable. There are no watercourses or direct
connectivity from the site to any watercourses. The implementation of relevant environmental protection
measures (Section 6) is expected to effectively mitigate potential adverse effects associated with soil
excavation.

6. ENVIRONMENTAL PROTECTION PLAN
The environmental performance standards for the project are provided in the following tables.
Specification and requirements for the project are as follows:
Ref. General Specifications
A1 All activities must comply with applicable laws and regulation including local bylaws and related
orders.
A2 All permit and approval conditions, terms and requirements must be implemented.
A3 All site personnel, including sub-contractors, must review and understand this EMP and sign the
Project Orientation Record (Appendix A).
A4 Environmental considerations must be a component of regular tailboard meetings.
A5 A project Environmental Monitor (EM) will be hired by the CVRD (project owners) to advise on
environmental issues and monitor contractor compliance with this EMP.
A6 In case of an environmental incident, a report must be filed within 24 hours, as per the Spill Response
Plan provided in Appendix D.
A7 A pre-construction site meeting should be held on site that includes the prime contractor, CVRD and
the EM to discuss the project approach and environmental performance standards.
A8 Vehicles and machinery will not be left idling on site. When equipment is not being used it should be
turned off and parked in a suitable, designated area
Ref. Archaeological Resources
B1 In the event of a chance archaeological find, the contractor shall suspend work and immediately notify
the CVRD.
B2 Discovered artefacts or sites of archaeological interest at the site are protected under the Heritage
Conservation Act. Under this Act, the contractor and its employees are responsible for protecting
archaeological resources uncovered during the course of work, this may include but is not limited to
human bones, pit houses, stone tools, rock paintings, shell deposits (middens) or culturally modified trees.
B3 If suspected human remains are found, the contractor shall stop work immediately and notify the CVRD
who will notify police. Do not disturb the site, stake or flag off the affected location to prevent additional
disturbance. Treat the remains with full dignity and respect and do not allow anyone to touch or
photograph the remains. Cover any exposed bones until police arrive. Assign an employee to watch over
the remains until the police arrive. Do not backfill the area.
Ref. Vegetation Management
C1 Prevent the introduction and spread of invasive species by cleaning equipment before arriving to the site.
Remove all plant and soil material from equipment and vehicles prior to arriving on site to avoid the
spread of invasive species.
Seal Bay: EMP July 21, 2021
9 | P a g e
C2 Separate cleared material containing invasive species from other cleared material and dispose of it at an
approved facility. No noxious weeds identified on Schedule A of the Weed Control Act have been
identified on the site. However, field work was conducted outside of suitable timing for identifying some
of these species so, while unlikely, it is possible they are present on site. If noxious weeds are noted on
site they will removed prior to commencing work and brought to the Comox Valley Waste Management
Centre at 3699 Bevan Road in Cumberland; inform the attendant that the material is noxious weeds. They
must covered and secured during transport. Note that one exotic species (Lamium galeobdolon) was noted
on site. Safe removal and disposal of this species prior to conducting soil excavation work is required.
The EM can assist with identification and determining the extent. At present only a few small patches are
expected.
C3 Keep equipment within the designated project footprint and conduct activities in such a manner that
avoids unnecessary disturbance outside of the footprint.
C4 Project limits should be clearly demarcated on the ground prior to commencing clearing.
C5 If grass seeding is required, seed mix must be approved by the CVRD prior to application.
C6 Any occurrence of rare or listed plant species must be immediately reported to the CVRD or EM. The
habitat within the Project Area was assessed to have a low likelihood of supporting listed plants.
C7 Deck merchantable timber in a disturbed area or within the project footprint in an area that is well drained
and free of standing water.
C8 Restore areas of bare soil as quickly as possible. This may include re-contouring to final grade /
engineering specifications and grass seeding and/or planting with appropriate species.
C9 The CVRD will work with the contractor to re-locate any planted seedlings that conflict with the project.
Ref. Management of Mature Trees
D1 An arborist (Ryan Murphy) has been retained to provide on-site advice for management of large trees
and danger tree modifications. Work around large trees should be conducted under an arborist’s
supervision.
D2 When falling large mature trees, care should be taken to avoid causing harm to adjacent trees being
retained. It is advised that large trees that are likely to cause mechanical damage to adjacent trees if felled
conventionally, be felled by a climbing arborist and sectioned down. Trees should be felled into the
project footprint to the extent possible.
D3 Use extreme caution when clearing or grubbing within the root zone of trees to be retained. Use a suitably
sized excavator and bucket to minimize root damage. Hand grubbing between large structural roots may
be necessary to avoid damaging tree roots. Root zones for the original design are provided in Appendix
C of the Arborist’s report (Appendix B). The root plates overlain on the new design is provided in
Appendix C: Figure 1.
D4 Avoid unnecessary soil compaction within the critical root zones of trees (Appendix B: Figure 1). This
applied a considerable portion of the work site so care will be required throughout constructions.
Seal Bay: EMP July 21, 2021
10 | P a g e
D5 Special consideration should be made with respect to removal of stumps within the critical root zone of
retained trees. If stumps in these locations must be removed, grinding is recommended to avoid damaging
interconnected roots of retained trees.
D6 Upon completion of construction, monitoring of edge trees where roots have been altered as a result of
the project will be required. Some retained trees along the boundary may degrade as a result of mechanical
damage to roots, soil compaction, or additional exposure from clearing. Note that visible symptoms may
take many months to express. These trees may become danger trees over time and may require further
management. It’s recommended that annual monitoring of the health of these trees be conducted for a
period of five years post project completion.
Ref. Soil Management
E1 Excavated soil piles must be stockpiled within an area approved by EM at least 15 m from any drainage
features (i.e., natural drainages, ditches, etc.) and 30 m from any watercourse (i.e., stream). If this cannot
be met, the EM should be engaged to provide specific mitigation. Site selection should be approved and
may require installation of perimeter sediment fencing and/or poly cover for stocked soil.
E2 Surface organics (organic soil, litter, fibre and humus) and topsoil will be stripped and stored separately
from the mineral soil (sub soil). The EM can advise on stripping depths. They are typically denoted by a
colour change. Avoid mixing of mineral and organic soils (admixing).
E3 Sediment resulting from soil stockpiling or machine disturbance must be cleaned up immediately. Public
driving surfaces (Bates Rd) must be kept free of soil and organic material originating from the project.
E4 Minimize soil exposure and potential degradation by restoring disturbed soils as soon as possible
following construction.
E5 If soil is being moved off site, the receiving location must be pre-approved by the CVRD and project
EM.
E6 Any fill brought to site must clean and free of hazardous contaminant and free of seed or plant fragments
from invasive plants. The source of materials may be checked by the EM to ensure that it is weed free.
E7 Notify the EM immediately if suspected soil contamination is encountered (i.e., stained, unusual odour
or colour or suspect buried debris such as demolition waste, old tanks, etc.) and stop work in the area
until the material can be characterized.
E8 Apply water to exposed dry soils in the work area during periods of high winds or dry weather to control
dust.
E10 Avoid soil handling or equipment movement during periods of intense rainfall that result in saturated soil
conditions. Work with the EM to determine when rainfall warrants a stop work.
Ref. Erosion and Sediment Control
F1 Erosion and sediment control measures should be installed prior to starting work. At a minimum, the
eastern boundary (downslope) of the work area should have sediment fence installed to contain
disturbance to the footprint. Sediment fence should be buried a minimum of 10 cm into the soil. Based
Seal Bay: EMP July 21, 2021
11 | P a g e
on conditions and weather, continue to assess the need for and implement additional erosion and sediment
control measure and practices to prevent sediment from flowing off-site.
F2 Contingency supplies of erosion and sediment control materials shall be on site and workers shall be
sufficiently trained in their appropriate installation and maintenance. At a minimum, the following should
be available:
200 m of sediment fencing;
One 3-inch water pump, or two 1.5-inch water pumps with 50 m of hose; and
Adequate poly sheeting to cover soil piles.
F3 Ensure all drainage features in the project area are protected from the release or inflow of sediment-laden
water related to the Project.
F4 Regularly inspect sediment and erosion control measures and conduct an inspection after rainfall events
of 15 mm or more. Maintain and repair, as necessary.
Ref. Wildfire
G1 As per the Wildfire Act and Regulation, restrictions will be implemented for construction operations that
fall under the definition of a “high risk activity” of the Wildlife Regulations conducted between March 1
and November 1. ‘High risk activities’ include mechanical brushing or land clearing and use of fire or
spark inducting tools (e.g., chain saws). Restrictions are provided here:
https://www.bclaws.gov.bc.ca/civix/document/id/complete/statreg/11_38_2005#Schedule3
The nearest wildfire weather station to the Project is the Campbell River Airport, approximately 30 km
to the north-northwest. The contractor will be responsible for determining daily fire danger ratings and
restrictions from the Coastal Fire Centre during for all works between March 1 and November 1.

G2 If clearing is to occur between March 1 and November 1, the contractor must prepare a Wildfire
Management Plan that should be submitted to the CVRD for review and acceptance. This plan should
include a contractor responsibilities for fire prevention, emergency response plan, reporting requirements,
training, provision of fire suppression equipment and tools to be provided and a description of any
additional procedures with regards to fire prevention.
G3 Restrictions placed on high risk construction operations may include:
Maintenance of a fire watch after work after three consecutive days of ‘moderate’ (or greater)
fire danger
Cessation of high risk activates between 13:00 and sunset after three consecutive days of ‘high’
(or greater) fire risk; and,
Cessation of high risk activities all day after three consecutive days of “extreme” fire risk.

Ref. Wildlife
H1 A pre-clearing walkthrough should be conducted to ensure that amphibians or other wildlife are not going
to be impacted by construction works. If amphibians are present abatement will be used to move them
out of the construction area and out of harm’s way. Depending on the result of the pre-clearing survey,
additional surveys during construction may be recommended.
H2 Identify and demarcate any resources that should be salvaged or protected (wildlife trees, nurse logs,
planted seedlings, etc.). Work with the CVRD and the EM to retain or relocate these features
appropriately before construction commences.
H2 Excavations must be fenced or covered to prevent wildlife entrapment and ensure public safety.
H2 Do not destroy, remove or clear any bird nests. If a bird nest is encountered, cease work at the site (a
minimum 30 m from the nest) and contact the EM.
H3 Clearing should be conducted outside of the migratory bird nesting window (March 26 to August 9) to
avoid non-conformance with the Migratory Bird Convention Act. If clearing cannot be conducted within
this period, a pre-clearing nesting bird survey must be conducted prior to clearing work. It is advised that
clearing works not be conducted between May and July as this corresponds to the peak of the breeding
period for this region and is likely to result in project delays.
H4 A pre-clearing walkthrough should be conducted to ensure that amphibians or other wildlife are not going
to be impacted by construction works. If amphibians are present abatement will be used to move them
out of the construction area and out of harm’s way.
H5 Ensure proper drainage of surface water during construction to avoid any pooling. Temporary pools and
surface water can attract breeding amphibians and cause conflicts with the project. Immediately contour
disturbed soils to effectively drain them.
H6 Implement Best Management Practices for Raptor Conservation during Urban and Rural Land
Development in BC:
http://www.env.gov.bc.ca/wld/documents/bmp/raptor_conservation_guidelines_2013.pdf
H7 Ensure proper storage of potential wildlife attractants such as food, garbage, petroleum products, or other
material with strong odours.
H8 Limit work to daytime hours, to the extent possible.
H9 Do not feed, disturb or harass wildlife. If wildlife are encountered allow to passively disperse, or if
necessary, contact EM for advice on abatement or relocation.
H10 Notify the EM of any evidence of bats using the area including observations of bats, potential roosts in
trees or guano (bat droppings). Cease work and maintain a 10 m distance from the observation until
further directed by the EM.
H11 All sightings of rare or endangered species (wildlife and plants) must be reported to the EM.
H12 Personnel pets are not allowed on the worksite.
Seal Bay: EMP July 21, 2021
13 | P a g e
H13 Wildlife observations should be recorded in an incidental wildlife log, kept on site and provided to the
EM and CVRD.
Ref. Water Quality
I1 Any water discharged from the site must meet the BC Water Quality Guidelines. Water to be discharged
must have a pH of between 6.5 and 9.0. If pumping of turbid water is required, the EM should be engaged
to determine a suitable pump-out location (generally, away from watercourses into well-vegetated areas
that can filter sediment).
Ref. Non-hazardous Waste
J1 Ensure all waste, litter and other construction-related materials are removed from the site and disposed
of appropriately.
J2 Keep the site clean and tidy. Clean up the site at the end of each work day and ensure that all waste
generated from construction is managed appropriately.
J3 Provide sanitary facilities for workers use if adequate facilities on site are not available. Facilities must
be secure and located at least 30 m from the top of the bank of any watercourse. These should be kept
clean and in good working order, and emptied regularly.
J4 Regularly inspect the site for general cleanliness and adherence to this EMP.
Ref. Fuel Handling
K1 Plastic containers used to carry petroleum products shall be designed and used for that sole purpose.
K2 Ensure proper containment for petroleum storage, transfer and refuelling facilities that may contain any
spillage or leakage.
K3 Any fuel or lubricants stored temporarily on site must have secondary containment capable of holding
110% of the contents of the container. Containment should be protected to prevent it from filling with
precipitation.
K4 Ensure fuel/oil storage containers are not placed within 30 m of a watercourse.
K5 Verify that containers do not leak and are sealed with a proper fitting cap or lid
K6 Label containers according to the Transportation of Dangerous Goods Act Regulations.
K7 Ensure equipment and machinery arriving on site is leak free.
K8 Perform construction activates in a manner that prevents the release of oil, fuel, coolant or other pollutants
into the environment.
Ref. Spill Response
L1 Report all spill and leaks, regardless of volume, to the EM as soon as possible.
Seal Bay: EMP July 21, 2021
14 | P a g e
L2 Keep a fully stocked emergency spill response kit appropriate to the work on site. Spill kits shall be
located in each piece of equipment at all times. Spill response material shall include an adequate inventory
of sorbent pads, socks and booms to sufficiently respond to petroleum leaks and spills from construction
related activities.
L3 Review and understand the Spill Response Plan provided in Appendix D.
7. RESPONSIBILITIES
7.1. Comox Valley Regional District (CVRD)
The CVRD is the Project owner and is responsible for application and approval of all necessary permits.
The CVRD may require or conduct surveillance of the Project throughout construction to ensure the work
is being carried out as per the contract requirements and conditions of this EMP and project
authorizations. The CVRD will lead, or delegate, communications with regulatory agencies, First Nations
and the public.
7.2. Prime Contractor
The prime contractor is responsible for constructing the project in a safe and appropriate manner as per
the requirements of the tenure including compliance with this EMP, relevant Best Management Practices
(BMPs) and any other requirements associated with project authorizations.
The prime contractor, its staff and any sub-contractors or other project personnel must read and
