Targeted Designated Substance Investigation
Woodroffe High School – Window Replacement 2016
CM3 Environmental (CM3) was commissioned by the Ottawa Carleton District School Board
(OCDSB) to complete a project-specific review for designated substances and hazardous materials
at the above referenced site.
The assessed area was limited to the parts of the building
within the area to be renovated. The extent of the assessed
area was outlined by the Client and is shown on the attached
drawings (Refer to Appendix A). The building was previously
assessed by Others in 2007 as per the report entitled
“Designated Substance Survey Ottawa Carleton District
School Board, Woodroffe High School Ottawa, Ontario”, dated
September 2007. Findings from this report have been relied
upon for the purposes of this assessment.
Regulatory Requirements
The completion of this survey and the presentation of the findings herein were made to fulfill the
Owner's requirement to complete a project specific/targeted Designated Substance Survey(DSS) to
comply with Ontario Regulation 278/05, “Regulation Respecting Asbestos on Construction Projects
and in Buildings and Repair Operations” and Section 30 of the “Occupational Health and Safety
Act”.
CM3 further enhanced the survey to include all other designated substances regulated under
Ontario Regulation 490/09 of the Occupational Health and Safety Act OHSA. Under Section 30 of
the OHSA, a project “owner shall determine whether any designated substances are present at the
project site and shall prepare a list of all designated substances that are present”.
The following is a list of substances regulated by O.Reg 490/09:

Scope
This report is based on the site inspection that was conducted on February 15, 2016 by Adam
Nguyen of CM3 Environmental Inc. (CM3). The subject facility is owned and operated by the
OCDSB and is located at 2410 Georgina Drive, Ottawa, Ontario.
Non-destructive survey techniques were employed during the site reconnaissance. The visual
inspection and sampling (in the original DSS), was limited to readily accessible areas and was
completed to comply with all applicable regulations. The survey did not include the demolition of
ceilings or walls, or other areas to examine concealed conditions.
The designated substances mentioned above may be present in partial and non-accessed areas
and concealed spaces (i.e. wall, columns and ceiling cavities). Furthermore, materials located
within wall cavities and in columns could not be observed in order to determine their content or
condition. In addition, CM3 would extrapolate quantities based on quantities observed in fully
accessible locations.
This targeted designated substance survey report has been prepared using the information provided
to CM3 by the OCDSB, through information obtained during the site reconnaissance and analytical
data.
In addition, the survey does not refer to substances that may be present in the day-to-day usage for
other specialized equipment or areas in buildings (i.e. portable equipment, lead shields, fume
hoods, etc.). There is a possibility that materials may exist which could not be reasonably identified
within the scope of this assessment, or which were not apparent during previous site visits.

Analytical Procedure
Suspect materials were primarily assessed by visual inspection. On the basis of this inspection,
select samples were collected from discrete locations using industry-accepted, safe sampling
techniques that include the pre-wetting of materials and concealment of materials after collection.
The number of samples collected is based on the suspect building materials present and the
sampling criteria outlined in Table 1 “Bulk Materials Samples” of Ontario Regulation 278/05.
A total of 206 asbestos bulk samples were previously collected by others. Nine (9) additional
samples collected were submitted to EMSL Canada Inc in Ottawa, Ontario. Samples were analyzed
by polarized light microscopy with dispersion staining, following USEPA method 600/R-93/116.
EMSL Canada Inc.participates in the National Voluntary Laboratory Accreditation Program (NVLAP
# 200877-0). All samples were submitted on a positive stop basis, meaning that similar samples
were not analyzed if the preceding sample was confirmed to contain asbestos.
The laboratory analytical reports are presented in APPENDIX B.
Findings
The following hazardous materials could be disturbed as part of
the window replacement.
Asbestos
1960 Phase of Construction
 Plaster walls found around windows. (3% Chrysotile
asbestos)
 Plaster walls with texture finish found around windows.
(2% Chrysotile asbestos)
 Plaster ceiling found above windows. (5% Chrysotile
asbestos)
 Transite boards found as soffits on the exterior of
building above windows. (20% Chrysotile asbestos)
 Red black and grey exterior finish found above and
below windows. (2% Chrysotile asbestos)
1961 Phase of Construction
 Plaster walls found around windows. (3% Chrysotile asbestos)
 Plaster ceilings found above windows. (3% Chrysotile asbestos)
 Plaster walls with texture finish found around windows. (2% Chrysotile
asbestos)
 Exterior brick mortar around windows. (1-2% Chrysotile asbestos)
 Red black and grey exterior finish found above and below windows. (2%
Chrysotile asbestos)
 Exterior grey caulking found around windows. (2% Chrysotile asbestos)

Other asbestos-containing materials are present within the building.
Lead
Lead is a naturally occurring metal element and is the most common metal found in the
environment. Pure metallic lead was primarily used to make products such as electric storage
batteries, ammunition, solder, radiation shields, pipes and sheaths for electric cables. The most
common organic lead compounds are tetraethyl (TEL) and tetra methyl (TML) lead that were used
as anti-knock agents in gasoline. Inorganic lead compounds such as lead oxides, chromates,
carbonates and nitrates are commonly found in insecticides, pigments, paints, frits, glasses, plastics
and rubber compounds.
A total of 25 samples of paint chip samples were collected by others. Paint chip samples were
collected from painted surfaces within the building. All paint chip samples were collected by
scraping the paint down to the base material substrate to ensure collection of all layers of paint.
Care was taken to avoid collection of the underlying substrate to reduce analytical substrate matrix
interference.
A variety of paints were observed throughout the building. The paint samples submitted for analysis
represent the overall majority of paint that exists within the assessed area. Paints that exist on a
single door, a cabinet, a small area, etc., may be considered lead based paint. Portions of the
building have been painted with new products, and are unlikely to contain lead (Pb). No additional
lead samples were taken.
The following paint samples with elevated concentrations of lead that may be affected during the
window replacement project are as follows:


SL-08 White Wall Paint – 1620ppm
SL-11 Beige Wall Paint – 1010ppm
Silica
Free crystalline silica is expected to be present within all plaster finishes, concrete and mortar based
building materials as well as acoustic ceiling tiles.
Recommendations
Asbestos
Since some of the window framing extents right to the ceiling, and due to the presence of asbestoscontaining ceiling plaster, wall plaster and plaster with texture finish, transite boards, caulking, brick
mortar and exterior texture finish, asbestos abatement measures and procedures are required prior
to the window extraction.
Based on the scope of the window replacement, the friable nature of the ceiling and wall plaster, the
exterior red, black and grey colored finish and brick mortar a minimum Type 2 measures and
procedures are recommended if less than 1 meter square of the ACM materials are being removed
using hand held tools only; although Type 3 abatement precautions may be required if power tools
are being used or quantities exceed more than 1 meter square as per Ontario Regulation 278/05
“Regulation respecting asbestos in Construction Projects and in Buildings and Repair Operations”.
4
File: RM1845
February 2016
Type 1 abatement procedures will be required for the removal of the exterior caulking around the
windows and the transite boards above the windows.
Lead
If work on lead containing materials is likely to produce lead dust or fumes, for example during
welding, torch cutting, grinding, sanding or sandblasting, then proper precautions should be
followed. As best industry practice, CM3 recommends that the ministry of Labour “Guideline for
Lead on Construction Projects” be followed when working with potential lead hazards.
The Time-Weighted Average Exposure Limits (TWAEL) of a worker to lead is to be maintained at
the lowest practical level and not exceed an eight hour average concentration of 0.05 mg/m³ of air
for non-tetraethyl lead and 0.10 mg/m³ of air in the case of tetraethyl lead.
Silica
Silica occurs naturally as crystalline material in concrete and cement. Crystalline silica is
significantly more toxic than amorphous silica. Therefore for health reasons, only crystalline varieties
are regulated under Ontario Regulation 490/09 as one of the designated substances. Silica dust
can be generated through such processes such as blasting, grinding, crushing or sandblasting
silica-containing material. Silica is often found contained within concrete walls, stairs and ramps.
Therefore, appropriate respiratory protection and ventilation must be utilized during construction and
demolition. As best industry practice CM3 recommends that the ministry of Labour “Guideline for
Silica on Construction Projects” is followed when dealing with potential silica hazards.
All other designated substances pose no health and safety concern for the window renovations.
