Designated Substances Survey i Mega 6 Bridge Rehabilitations 23 Bridge Structures on Highways 417, 416 and 34 MMM Group Limited | October 2015 | W.O. 4014-E-0015

The purpose of this assessment is to meet the requirements of the Occupational Health and Safety Act , to identify the potential for, location of, and quantity of designated substances identified during the survey (as applicable) and to provide applicable management considerations for each designated substance identified. Available background documentation (including the Ontario Bridge Management System, Ontario Structure Inspection Manual – Inspection Forms, Utility Duct Assessment Letters and contract drawings) were reviewed to determine the potential for designated substances at each of the structures. Following the background review, a Site inspection was conducted at each structure and a non-destructive sampling program was completed, where potential designated substances were identified and accessible. The following is a summary of the DSS observations for the bridge structures inspected during this survey:

Site No. Summary of Findings

• Based on the document review, it was determined that there is no potential for asbestos containing material (ACM) to be incorporated in the building materials for the electrical conduits, adaptors and fittings in any of these bridges. • Silica is present in concrete and mortar. Standard dust control measures should be implemented where practical to ensure airborne dusts are controlled during construction activities. • Epoxies and coatings on steel elements (guiderails, bracing, girders, diaphragms, beams, etc.) may contain lead, arsenic and mercury. All Bridges Arsenic may also be present in pressure treated lumber in guiderail posts. • Materials that become exposed during bridge rehabilitation (i.e. insulation, electrical wiring, asphalt, cables and piping), that support the suspicion of asbestos or other designated substances should be sampled at that time to confirm the presence or absence of asbestos to determine appropriate management options. • MMM did not identify the presence of the following designated substances: acrylonitrile, benzene, coke oven emissions, ethylene oxide, isocyanates and vinyl chloride.

Group A

SN-3-540 • SN-3-542/1 & 2 Concrete samples collected from the west abutment wall at SN-27-50 were submitted for asbestos analysis. The results of the sample analysis SN-3-543/1 & 2 indicated that the concrete samples do not contain asbestos. No SN-3-550/1 & 2 additional samples were submitted for asbestos analysis. • Paint sample collected from the steel plate girders beneath the bridge SN-27-198 structure SN-3-550/1 did not exceed the Canada Consumer Product SN-27-50 Safety Act guidelines for lead (0.0039% vs. 0.009%). SN-3-549/1 & 2

Site No. Summary of Findings

Group B

• Concrete samples collected from the north abutment wall at SN-3-39/2 were submitted for asbestos analysis. The results of the sample analysis SN-3-39/1 & 2 indicated that the concrete samples do not contain asbestos. No additional SN-3-40 concrete samples were obtained. • Paint samples collected from the steel plate girders beneath structures SN- SN-3-41 3-39/1, SN-3-40, SN-3-41 and SN-3-42 were submitted for analysis of SN-3-42 lead. Based on the analytical results, all of the paint samples with the exception of the sample collected from SN-3-40 exceeded the Canada Consumer Product Safety Act guidelines.

Group C

SN-3-552 • Samples collected from the conduit in the west curb at SN-3-288 were SN-3-553 submitted for asbestos analysis. The results of the sample analysis indicated that the material does not contain asbestos. SN-3-554 • Orange fibrous batting insulation was observed between the concrete SN-3-357 abutment walls at SN-3-357. Samples were obtained and submitted for asbestos analysis. The results of the sample analysis indicated that the SN-3-569 material does not contain asbestos. SN-3-570 • No paint was visually identified at any of the structures and no samples were obtained.

1.2 Scope of Work

The DSS considered the age of the structures and typical manufacturing processes for building materials in the assessment of potentially hazardous substances. The scope of work included the following: • Review of available drawings of the existing structures; • Visual assessment of building materials for the presence of designated substances and/or hazardous materials; • Recovery of non-destructive and representative samples of bridge materials and submission for laboratory analysis, as required. However, this work program did not include destructive sampling of road surface for asbestos containing material (ACM); • Review of the Preliminary Design drawings; and • Preparation of a summary report documenting the findings of the DSS.

2.0 REGULATORY CONTEXT

Based on the MTO Guideline for the Identification of Designated Substances (MTO DSS Policy), coatings on structures and steel elements (guiderails, conduits, bracing, girders, diaphragms, beams, etc.) may contain lead, asbestos, arsenic and mercury. Arsenic may also be present in pressure treated lumber used in guiderail posts. Silica is suspected to be present in concrete, mortar and block used in construction of bridges. Between the 1960s and the 1980s, in some areas of Ontario, asbestos was added to asphalt mixtures and applied to road surfaces. Asphalt testing should occur, if future rehabilitation activities include asphalt replacement. A total of 11 designated substances are regulated under the Occupational Health and Safety Act (OSHA). These include: acrylonitrile, arsenic, asbestos, benzene, coke oven emissions, ethylene oxide, isocyanates, lead, mercury, silica, and vinyl chloride. Of these 11 designated substances, asbestos, lead, silica, arsenic, and mercury are more commonly found in older bridge structures and as such are applicable to this project. In addition to those listed above, this report also considered polychlorinated biphenyls (PCBs). These designated substances are briefly described below.

2.1 Asbestos

Asbestos is a commercial term given to six naturally occurring minerals that are incombustible and separable into fibres. The fibres are strong, durable and resistant to heat and fire and are long, thin and flexible enabling them to be woven into cloth. These qualities have resulted in the wide use of asbestos in commercial, industrial, automotive and building materials. Common ACMs include pipe-coverings, insulating cement, insulating block, transite board, conduits/ducts, fireproofing spray, joint compound, mastics, bearing components as well as in coatings found on structures and culverts (i.e. asphalt coated asbestos protected corrugated steel). Although the common construction use of friable (crumbles easily under hand pressure) ACM generally ceased voluntarily in the mid-1970s, it was not until the mid to late 1980s that ACM use was banned through legislation. Asbestos fibres were used in some concrete products in the past; however, asbestos fibres were typically added to precast materials including flat and corrugated sheets, pressure pipes and fire-resistant boards. These materials were not typically used during construction of the

6 Designated Substances Survey Mega 6 Bridge Rehabilitations 23 Bridge Structures on Highways 417, 416 and 34 MMM Group Limited | October 2015 | W.O. 4014-E-0015

main components of bridges (i.e. concrete footings); however, precast products are typically used in piping and conduits for electrical, mechanical and drainage systems. Under Ontario Regulation (O. Reg.) 278/05 and OSHA regulations in effect for Ontario, material containing 0.5% by dry weight or more of asbestos fibres is considered ACM.

2.2 Lead

Lead can be present in paint and/or other coatings on steel elements (guiderails, conduits, bracing, girders, diaphragms, beams, etc.), bearing plates and steel/rebar. Lead was used as a white pigment in paint until the mid-1950s, in concentrations as high as 50% by weight. As such, bridges built before the mid-1950s are likely to contain lead based paint (LBP). Smaller amounts of lead may also be found in bridges constructed up to 1980. Under the Surface Coating Materials Regulation (2005, Amended 2011) under the Canada Consumer Product Safety Act, paint containing lead in excess of 0.009% (90 mg/kg) is controlled in Canada. This limit, implemented in 2010, is among the strictest in the world and applies to paint and painted products offered for sale. This standard does not apply to existing painted surfaces. In the absence of Canadian regulations for existing surfaces, the U.S. Housing and Urban Development (HUD) guideline was consulted. HUD defines any paint containing over 0.5% (5,000 mg/kg) or 1.0 mg/cm3 of lead to be LBP. HUD also considers any dried paint that contains lead exceeding 0.009% (90 mg/kg) as lead-containing paint (LCP). This lower concentration value is used for evaluation in this report. In general, standard dust control practices for activities associated with building renovation are sufficient to control dust from exposed painted surfaces with less than 5,000 mg/kg lead. At higher concentrations, abatement, worker protection or enhanced dust control measures may be required. Should painted surfaces be grounded, sanded or otherwise abraded, the effects of any works on the underlying substrates of paint should be considered in the development of dust control measures. The classification of typical lead-containing construction tasks is based on presumed airborne concentrations obtained from the U.S., OSHA, the Ontario Ministry of Labour (MOL), and published research studies. The classification of Type 1, Type 2, or Type 3 operations are grouped based on the following concentrations of airborne lead:

Type 2 Operations Type 3 Operations Type 1 Operations Type 2a Type 2b Type 3a Type 3b

< 0.05 mg/m 3 > 0.05 to 0.5 mg/m 3 >0.5 to 1.25 >1.25 to 2.5 >2.50 mg/m 3 mg/m 3 mg/m 3

2.3 Silica

Silica is a naturally occurring mineral and can be present in materials used for building construction, such as mortar, concrete, block and brick. Silica is a designated substance and dust generated through the handling of materials containing silica must be controlled. If future renovation activities affect the integrity of these materials, standard demolition dust control measures should be implemented where practical to ensure airborne dusts are controlled.

Designated Substances Survey 7 Mega 6 Bridge Rehabilitations 23 Bridge Structures on Highways 417, 416 and 34 MMM Group Limited | October 2015 | W.O. 4014-E-0015

2.4 Arsenic

Arsenic is a naturally occurring mineral and can be present in hot-mix asphalt (also referred to as asphalt concrete), pressure treated lumber (guiderail posts, retaining walls, supports, etc.), paint coatings on steel elements (guiderails, conduit, bracing, girders, diaphragms, beams, etc.) and creosote coatings (wood culverts, retaining walls, etc.).

2.5 Mercury

Mercury is commonly found in thermostats and electrical switches, as well as mercury vapour- containing fluorescent light bulbs. Based on the MTO DSS Policy, mercury is not likely to be encountered in fluorescent light bulbs as mercury vapour lamps have been replaced with high pressure sodium and light emitting-diode (LED) for illumination. In addition, paint coatings on steel elements may contain mercury.

2.6 PCBs

Light ballasts, capacitors and transformers have the potential to contain PCBs. If ballasts, capacitors or transformers are encountered during construction activities, label information should be inspected carefully. Typically, ballasts manufactured after 1978 are labeled “No PCBs”. Florescent light bulbs (FLB) manufactured before July 1, 1979 may contain PCBs, FLBs manufactured between July 1, 1979 and July 1, 1998 are labeled "No PCBs" and FLBs manufactured after 1998 are not required to be labeled.

2.7 Waste Management

The disposal of designated substances is regulated under the Ontario Environmental Protection Act (EPA), specifically O. Reg. 347, General Waste Management. The regulation outlines the requirements for the transport and disposal of wastes and outlines specific requirements for the containment and transport of waste. 3.0 STRUCTURE OVERVIEW

Available background documentation (including the Ontario Bridge Management System, Ontario Structure Inspection Manual – Inspection Forms, Utility Duct Assessment Letters, bridge contract drawings and structural rehabilitation drawings) were reviewed to determine the potential for designated substances to be present within each of the structures. Following the background review, a Site inspection was conducted at each structure and a non-destructive sampling program completed, if potential designated substances were identified and were accessible for sampling.

A review of the general agreement drawing dated May 1993 identified that electrical conduits embedded in the barrier walls are rigid PVC. Electrical capacitors located within the cable sheaths may contain PCBs (if present). 3.1.1.2 Structure Description and Site Observations A Site inspection was completed on May 27, 2015. SN-3-540, comprised of concrete construction, is a circular voided slab bridge and the outer limit of the structure has concrete barrier walls ( Photograph 1). This site is located at the junction of Highway 417 and Highway 416 and carries two east-south ramp lanes over the south-west ramp lanes. 3.1.1.3 Conclusions and Recommendations Based on the document review, it was determined that there was no potential for ACM to be incorporated in electrical conduits, adaptors and fittings as the 1993 general agreement drawing identified that the electrical conduits embedded in the barrier walls of SN-3-540 are rigid PVC.

In addition, the Detailed Condition Survey Report dated March 9, 2015, confirmed the conduits were embedded in the east and west barrier walls and were PVC. Electrical capacitors located within the cable sheaths may contain PCBs (if present). 3.3.5.2 Structure Description and Site Observations A Site inspection was completed on May 28, 2015. SN-3-569 is a two-span, post-tensioned circular voided deck structure with an asphalt wearing surface (Photograph 24 ). This Site is located on McGee Road at Highway 417 approximately 5km west of Highway 7, Stittsville, ON. During the Site inspection, concrete samples (CRT-4A, CRT-4B and CR-4C) were collected from the east abutment. As the bridge was constructed in 1992, the concrete materials are not suspected to contain asbestos therefore analysis for asbestos was not carried out. 3.3.5.3 Conclusions Based on the document review, it was determined that there was no potential for ACM to be incorporated in electrical conduits, adaptors and fittings as the 1990 electrical embedded work drawing identified that the electrical conduits embedded in the barrier walls of SN-3-569 are rigid PVC.

3.3.6 SN-3-570; Highway 417 Richardson Road Underpass 3.3.6.1 Document Review Based on the Ontario Bridge Management System (OBMS), Ontario Structure Inspection Manual – Inspection Form dated December 16, 2013; the bridge was constructed in 1992. A review of the electrical embedded work drawing dated September 1990 identified electrical conduits in barrier walls are rigid PVC. Electrical capacitors located within the cable sheaths may contain PCBs (if present). 3.3.6.2 Structure Description and Site Observations A Site inspection was completed on May 28, 2015. SN-3-570, comprised of concrete construction, is a circular voided slab bridge and the outer limit of the structures has concrete barrier walls ( Photograph 25 ). This Site is located on Richardson Road at Highway 417 approximately 2km west of Highway 7, Stittsville, ON. 3.3.6.3 Conclusions and Recommendations Based on the document review, it was determined that there was no potential for ACM to be incorporated in electrical conduits, adaptors and fittings as the 1990 electrical embedded work drawing identified that the electrical conduits embedded in the barrier walls of SN-3-570 are rigid PVC. During the Site inspection no samples were obtained. 3.3.7 SN-3-288; Highway 417- Highway 7 Connection Overpass 3.3.7.1 Document Review Based on the Ontario Bridge Management System (OBMS), Ontario Structure Inspection Manual – Inspection Form dated December 16, 2013, the bridge was constructed in 1974 and rehabilitation was conducted in 2000. A review of the general agreement drawing dated March 1972 identified one electrical conduit in the west parapet wall and two Bell Canada conduits in the west curb. A review of the electrical embedded work drawing dated January 1974 indicated that electrical conduits embedded in the west barrier wall and curb were asbestos cement, PVC or fiber conduits. Comparison between the electrical embedded work drawing dated 1974 and the electrical embedded work drawing dated April 2000 indicated that only the conduit embedded in the west barrier wall has been replaced with a single 75 mm PVC conduit. Electrical capacitors located within the cable sheaths may contain PCBs (if present). 3.3.7.2 Structure Description and Site Observations A Site inspection was completed on May 28, 2015. SN-3-288, comprised of concrete construction, is a circular voided slab bridge and the outer limit of the structure has concrete barrier walls ( Photograph 26 ). This Site is located at the junction of Highway 7 and Highway 417 and is a single lane of Highway 7 to the Highway 417 westbound ramp lane, in Stittsville, ON. During the Site inspection conducted by the MMM structural engineers, duct samples (DUCT1A, DUCT1B and DUCT1C) were obtained from the west curb and submitted to Maxxam for analysis of asbestos.

4.0 SUMMARY OF FINDINGS

A summary of the entire DSS program is provided in Table 11.

Table 11: Summary of Findings

Site No. Summary of Findings

All Bridges • Based on the document review, it was determined that there is no potential for ACM to be incorporated in the building materials for the electrical conduits, adaptors and fittings in any of these bridges. • Silica is present in concrete and mortar. Standard dust control measures should be implemented where practical to ensure airborne dusts are controlled during construction activities. • Epoxies and coatings on steel elements (guiderails, conduit, bracing, girders, diaphragms, beams, etc.) may contain lead, arsenic and

Site No. Summary of Findings mercury. Arsenic may also be present in pressure treated lumber in guiderail posts. • Materials that become exposed during bridge rehabilitation (i.e. insulation, electrical wiring, asphalt, cables and piping), that support the suspicion of asbestos or other designated substances should be sampled at that time to confirm the presence or absence of asbestos to determine appropriate management options. • MMM did not identify the presence of the following designated substances: acrylonitrile, benzene, coke oven emissions, ethylene oxide, isocyanates and vinyl chloride.

Group A

SN-3-540 • Concrete samples collected from the west abutment wall at SN-27-50 SN-3-542/1 & 2 were submitted for asbestos analysis. The results of the sample analysis SN-3-543/1 & 2 indicated that the concrete does not contain asbestos. No more concrete SN-3-550/1 & 2 samples were submitted for asbestos analysis, since all of the Sites with the exception of SN-27-50 were constructed after 1970. SN-27-198 • Paint sample collected from the painted steel plate girders beneath the SN-27-50 bridge structure SN-3-550/1 did not exceed the Canada Consumer Product Safety Act for lead (0.0039% vs. 0.009%). SN-3-549/1 & 2

Group B

• Concrete samples collected from the north abutment wall at SN-3-39/2 were submitted for asbestos analysis. The results of the sample analysis SN-3-39/1 & 2 indicated that the concrete does not contain asbestos. No additional SN-3-40 concrete samples were obtained. • Paint samples collected from the steel plate girders beneath structures SN- SN-3-41 3-39/1, SN-3-40, SN-3-41 and SN-3-42 were submitted for analysis of SN-3-42 lead. Based on the analytical results, all of the paint samples with the exception of the sample collected from SN-3-40 exceeded the Canada Consumer Product Safety Act guidelines.

Used to evaluate the variance in the measurement. Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. QC Standard: A sample of known concentration prepared by an external agency under stringent conditions. Used as an independent check of method accuracy. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spiked amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than 2x that of the native sample concentration).
