Title: Wilmer Marsh Remediation
Location: Wilmer Marsh, BC
Work Description:
The site is located on the western side of the Columbia River
Valley and consists of remnant river bench upland with an
adjacent shoreline and marsh below. The benchland is relatively
flat, with steep slopes and gullies on the south, east and north
boundaries. Wilmer Marsh borders the site at the bottom of the
steep slopes to the east and is located approximately 60m lower
than the upland bench. A steep trail leads down to the marsh
along the southern edge of the uplands bench. The remediation
work areas are located in the marsh and in the trail area.
The Columbia NWA is a federally protected area designed to
conserve wildlife and their habitat and is not intended for
recreational uses. Refuse deposited at the site includes, but
is not limited to, automobile bodies and parts, cans, glass,
building debris, scrap metal, used oil containers and filters,
automotive batteries, drums, etc.
Due to the potential presence of sensitive species/habitat in
the proposed work areas at the site, all work must be conducted
under the supervision of Environmental Monitors (EMs). The
Environmental Monitor will notify the Departmental
Representative immediately and without delay at any time that
adverse impacts to sensitive species are observed or
anticipated. The Departmental Representative will in turn direct
the Contractor to stop work.
Due to the terrain and sensitive soils at the site, the work
will also be conducted under the supervision of Geotechnical
Monitors (GMs).
The EC Wilmer Marsh site remediation involves removal of
approximately 2600 m3 of refuse/debris with varying amounts of
soil. Specifically:
- Trail Area (Main Debris Zone): 45 m by 20 m area to a depth
of at least 1.5 m below grade (in situ volume of combined soil
and debris of 1350 m3).
- Trail Area (Area of Impact 3): 20 m by 20 m area to a depth of
2.5 m below grade (in situ volume of combined soil and debris of
1000 m3).
- Trail Area: removal of numerous pieces of surficial debris
(estimated volume of 200 m3).
- Marsh Area: removal of approximately seven large pieces of
debris (estimated volume of 50 m3). No sediment removal is to
be completed.
As unauthorized disposal of refuse occurred at the site, there
is the possibility that hazardous materials (e.g., asbestos,
lead piping, etc.) will comprise a portion of the debris present
on the site. The project work assumes that any hazardous
building materials encountered will be handled appropriately and
disposed at an appropriate facility.
Due to the location of the site within a NWA, limited material
handling/storage can occur on the site. Consequently, excavated
material (soil and debris) must be transported off-site to a
temporary staging area for separation (i.e. screening of soil
from debris) and characterization (i.e. ex situ soil sampling)
prior to disposal at the final, approved disposal facility. It
will be the contractor's responsibility to arrange for such an
off-site staging area (referenced in this document as the soil
and debris management facility) including obtaining the relevant
permits, approvals or authorizations (e.g. soil relocation
agreement).
Geotechnical assessment of the Main Debris Zone in the trail
area in 2013-2014 concluded that remedial excavation activities
in the area would accelerate surface erosion, gullying and slump
failure. The following mitigation measures were recommended:
- Reduce excavation areas and depths to minimize the total area
of disturbance and to reduce the height of potentially unstable
cut slopes. Consequently, excavation depths in the Main Debris
Zone will be limited under the proposed work program.
- Protect access routes on the site by installing a 300 mm thick
layer of well-graded, crushed angular gravel on a layer of
filter fabric. Canadian Wildlife Service has indicated that
construction of "roads" is not permitted at the site.
Consequently, no roads are to be constructed at the site and the
work program must be conducted under extended periods of dry, or
frozen, ground conditions.
- Utilize low-impact equipment such as rubber-tired or spider
hoe-type excavators (with operators experienced in working on
steep slopes) to reduce the potential for ground disturbance.
- Exercise caution in operating equipment in the vicinity of the
void identified on the lower trail.
- Construct cross-ditches at the top of the trail work area to
divert surface flow from the work areas.
- Construct cross-slope terraces along long sections of steep
uniform slopes to break the slope and slow surface runoff along
the slope.
- Implement erosion and sediment control measures including
deposition of coarse woody debris and installation of coconut
fibre mat cover. Coarse woody debris is to be sourced from
other areas of the site or adjacent lands to minimize the
potential for introduction of invasive species.
Mandatory Site Visit:
A mandatory bidder's meeting will be held on December 17, 2014
at 9am PST at Wilmer Marsh. Once arriving to the town of Wilmer
(approx. 10 mins outside Invermere), follow Main Ave which leads
into Westside Rd and becomes a gravel road shortly outside of
town. The site is approx. 1km from this point on the right side
of the road. Everyone attending the bidder's meeting should wear
appropriate PPE for the conditions (ice, snow), including
appropriate footwear as the marsh is located at the bottom of a
steep trail.
The site visit for this project is MANDATORY. The
representative of the bidder will be required to sign the Site
Visit Attendance Sheet at the site visit. Bids submitted by
Bidders who have not signed the attendance sheet will not be
accepted.
Interested bidders who intend on attending the site visit are to
provide their name(s) and company name(s) to Patty Liu at
P••••••••@•••••.••.ca no later than 24 hours prior to the site
visit.
Delivery Date:
Remediation and restoration activities are to be completed
within the wildlife, fisheries and fiscal year windows for the
site (January 5 to March 13, 2015). All final submittals must
be completed by March 31, 2015.
