CONTAMINATION OVERVIEW STUDY, 16TH AVENUE, MARKHAM, ONTARIO

1.0 INTRODUCTION

Golder Associates Ltd. (“Golder”) was retained by HDR Inc. (“HDR”), on behalf of the Regional Municipality of York (York Region), to provide contaminated property and waste management consulting services in support of the 16th Avenue Municipal Class Environmental Assessment (Woodbine Avenue to York/Durham Line), in Markham, Ontario. The “Study Area” includes approximately 14.3 km of 16th Avenue, Woodbine Avenue to York/Durham Line. The Study Area and limits are presented on Figure 1 following the text of this report.

Golder’s level of work consisted of a Contamination Overview Study (“COS”) for the Study Area to assess the potential and/or actual environmental impact to the 16th Avenue right-of-way (“ROW”) within the Study Area which are identifiable from a visual examination of surface features through a “windshield” level reconnaissance and from available sources of information.

No soil, water, liquid, gas, product or chemical sampling and testing on, or in the vicinity of the Study Area was conducted as part of this assessment. This assessment included a cursory overview of the Study Area and does not constitute a complete assessment of these lands. 2.0 METHOD OF INVESTIGATION Information reviewed and agencies contacted as part of the COS consisted of:  Technical Standards Safety Authority (“TSSA”) Fuel and Safety Division Records (select addresses of interest);  EcoLog ERIS Report;  Aerial photographs; and,  Topographic and geologic mapping. A limited “windshield reconnaissance” within the Study Area was completed on May 19, 2017 to visually corroborate the background information reviewed. 3.0 SCOPE OF WORK 3.1 Information Review The assessment included a review of available and applicable references concerning the Study Area history and subsurface conditions, as well as a field reconnaissance. Details of the information reviewed are provided in the following sections of this report. 3.2 TSSA Fuel and Safety Division Records The TSSA maintains records related to registered underground storage tanks for petroleum-related products. The TSSA was contacted to establish the status of the properties within the Study Area and to identify outstanding instructions, incident reports, fuel oil spills, or contamination records. Based on our review of the Study Area and properties with a high probability of having associated TSSA records, the following properties were searched (from west to east):  3010 Woodbine Avenue, Markham

Table 3.2: Aerial Photograph Summary Original Year Information Summary Scale The area in the vicinity of the Study Area is mostly under agricultural land use. 1954 Interactive Several creek systems can be observed within the wooded areas across the study area, consistent with present day. 1970 Interactive The Study Area appears relatively unchanged from 1954. Residential development south of the Study Area from Woodbine Avenue to Ninth 1988 Interactive Line is observed. The remainder of the Study Area is relatively unchanged from 1970. A golf course is present north of the Study Area stretching from Warden Avenue to Kennedy Road. A large school is present at 6160 16th Avenue beside Mount Joy Lake. The beginning of residential development north of the Study Area along 16th 1999 Interactive Avenue between Shorthill Drive and McCowan Road is observed. Residential development north of the Study Area is now observed from Williamson Road to Ninth Line. The remainder of the Study Area is relatively unchanged from 1988. Additional residential development north and south of the study area is observed 2005 Interactive from Ninth Line to Donald Cousens Parkway. 2014 Interactive Study appears similar to the 2005 photograph.

3.3.2 Regional Geology According to Northern Development and Mines, 1971, the geology of the Study Area is predominantly characterized by undifferentiated till. The till consists predominantly a sandy silt to silty sand matrix with some clay and minor sand and gravel often high in total matrix carbonate content.

Bedrock underlying the Study Area consists of Ordovician aged limestone and shale of the (listed in order from youngest to oldest) Georgian Bay, Whitby, Lindsay, and Verulam Formations of the Simcoe Group (Ontario Ministry of Northern Department and Mines, 1991). Bedrock is anticipated at depths of approximately 50 m to 88 m below grade. 3.4 Field Investigation A visual site reconnaissance of the Study Area was conducted on May 19, 2017. At that time, the Study Area was visually assessed for the presence of potential sources of subsurface impacts which could impact the Study Area. 3.4.1 Existing Land Use Land use in the vicinity of the Study Area was observed to be a mix of undeveloped, residential, agricultural, commercial, and industrial land use, along with a cemetery, churches, and schools. Several properties were noted to have or to have had fuel use and/or storage and vehicle or equipment maintenance.

Properties with issues of potential environmental concern are reported by address in the sections below. If subsurface work is to occur in these areas, potential impacts associated with nearby addresses should be reviewed.

CONTAMINATION OVERVIEW STUDY, 16TH AVENUE, MARKHAM, ONTARIO

3.5 Summary of Findings

Based on existing land use information obtained and field investigations, there are a number of properties which may require further environmental investigation to assess the potential presence of subsurface impacts. In general, properties currently or historically developed as service garages, gas stations, dry cleaners, vehicle sales centres, auto body repair shops, manufacturing facilities, industrial properties and construction yards represent issues of potential environmental concern and impacts may be encountered during road improvements in the vicinity of these properties. Properties which require further background investigation generally include properties that appear to be vacant or newly occupied, but which had previously been developed for different uses. Any agricultural properties with active farming infrastructure (i.e., barns, sheds, livestock pens) within 50 m of the ROW have the potential for impacts associated with petroleum hydrocarbons, pesticides, and nutrients; however, cultivated fields would not typically have these issues.

It should be noted that there may be issues of potential environmental concern associated with properties that were not evident based on the level of assessment carried out as described in this report. Further, the issues of potential environmental concern are preliminary in nature and may not include all issues associated with the property. Additional background information is required to better characterize the potential site specific contaminants of concern.

Due to the approximate locations of spills obtained from the Ontario Spills database, information is provided for information purposes. Possible environmental impact may be associated with any spill location. 4.0 SUMMARY AND DISCUSSION Based on the preliminary information obtained to date and the windshield reconnaissance, the Study Area contains the following properties with issues of potential environmental concern. If subsurface work is to be conducted in the vicinity of these properties, further intrusive investigations may be required. If impact is encountered, it should be managed in consultation with a qualified professional. Twenty-three properties with issues of potential environmental concern were identified within the Study Area (see Table 4.1 below and Figure 1). Low Risk Ranking:  The property is located directly in, or immediately adjacent to, the 16th Avenue ROW;  Environmental impacts are likely limited in extent and likely only present in surficial soil:  Migration, exposure pathways and receptors are likely limited; and/or,  Impacts can likely be easily managed prior to or during construction. Moderate Risk Ranking:  The property is located directly in, or immediately adjacent to, the 16th Avenue ROW;  Environmental impacts are likely to be present across a large portion of the property;  Environmental impacts are likely present in soil and/or groundwater;  Migration, exposure pathways and/or receptors may be present; and/or,  Impacts would need to be assessed prior to the acquisition, design and/or construction.

October 5, 2017 Report No. 1538314 6

CONTAMINATION OVERVIEW STUDY, 16TH AVENUE, MARKHAM, ONTARIO

High Risk Ranking:  The property is located directly in, or immediately adjacent to, the 16th Avenue ROW;  Environmental impacts are likely widespread across the property;  Environmental impacts are likely present in soil and groundwater;  Impacts are likely mobile and migrating across, onto and/or off-Site;  Source of impacts is likely still present;  There are several receptors and exposure pathways; and/or,  Impacts would need to be assessed and addressed prior to the acquisition, design and/or construction. Table 4.1 summarizes potential additional environmental assessment programs based on information obtained to date.  Risk Ranking - Low: 19 properties require further assessment to determine whether subsurface investigations would be warranted (i.e. a Phase I ESA is recommended);  Risk Ranking - Medium: 12 properties require further assessment to determine whether subsurface investigations would be warranted (i.e. limited subsurface environmental investigations are recommended); and,  Risk Ranking - High: 11 properties require subsurface environmental investigations (i.e. Phase II ESAs) to determine whether soil and/or groundwater impacts exist at the properties.

Database Descriptions: This section provides a detailed explanation for each database including: source, information available, time coverage, and acronyms used. They are listed in alphabetic order.

Detail Report: This is the section of the report which provides the most detail for each individual record. Records are summarized by location, starting with the project property followed by records in closest proximity.

Distance: The distance value is the distance between plotted points, not necessarily the distance between the sites' boundaries. All values are an approximation.

Direction: The direction value is the compass direction of the site in respect to the project property and/or center point of the report.

Elevation: The elevation value is taken from the location at which the records for the site address have been plotted. All values are an approximation. Source: Google Elevation API.

Executive Summary: This portion of the report is divided into 3 sections:

'Report Summary'- Displays a chart indicating how many records fall on the project property and, within the report search radii.

'Site Report Summary'-Project Property'- This section lists all the records which fall on the project property. For more details, see the 'Detail Report' section.

'Site Report Summary-Surrounding Properties'- This section summarizes all records on adjacent properties, listing them in order of proximity from the project property. For more details, see the 'Detail Report' section.

Map Key: The map key number is assigned according to closest proximity from the project property. Map Key numbers always start at #1. The project property will always have a map key of '1' if records are available. If there is a number in brackets beside the main number, this will indicate the number of records on that specific property. If there is no number in brackets, there is only one record for that property.

The symbol and colour used indicates 'elevation': the red inverted triangle will dictate 'ERIS Sites with Lower Elevation', the yellow triangle will dictate 'ERIS Sites with Higher Elevation' and the orange square will dictate 'ERIS Sites with Same Elevation.'

Unplottables: These are records that could not be mapped due to various reasons, including limited geographic information. These records may or may not be in your study area, and are included as reference.
