1.0 REPORT PURPOSE

The RSC property is identified as former Hope Centre (municipal address 179-181 East Main Street,

Welland, ON), currently depicted as municipal address 179 East Main Street, Welland, ON. Historic land

use has included community use (Housing Help Centre and Hope Centre 2005-2015) in addition to

various commercial businesses since the early 1920’s. Hallex Environmental Ltd. (Hallex) was retained

by Mr. Tony Calzetta to conduct a Phase 2 Environmental Site Assessment (ESA) of 179 East Main

Street, Welland, ON (the site) following the completion of a Phase 1 ESA report that documented an Area

of Potential Environmental Concern (Hallex, July, 2015), being a former dry cleaner at the west adjacent

site.

This Phase 2 ESA conceptual site model provides an overview of the work completed to date as well as

representative characterization of soil and groundwater conditions for the RSC property. This RSC filing

is being completed for the purpose of changing land use from a less sensitive (commercial) back to a

more sensitive (residential) land use. The RSC property location and reference plan are located on Figures

1 and 2. The chronology of Environmental Site Assessment work at the RSC property includes:

• July 2015: Phase 1 ESA

• November 2015: Phase 2 ESA


3

2.0 REPORT ORGANIZATION

The phase 2 conceptual site model (CSM) is organized to follow the requirements as set out in O.Reg

153/04 Part IV, Schedule E section 43(2) to 43(9), as amended by O.Reg 511/09. The CSM is compiled

as per the Table of Contents.

3.0 CURRENT CONDITION OF THE PROPERTY OR, WHERE REMEDIAL ACTIONS HAVE BEEN UNDERTAKEN, THE CONDITION OF THE PHASE TWO PROPERTY BEFORE THE REMEDIAL ACTIONS WERE UNDERTAKEN

The current condition of the property is the former location of community use building: Hope Centre.

The majority of the study site is occupied by the building footprint with parking at the rear. The Phase 1

ESA activities identified one (1) Potentially Contaminating Activity (PCA) that designated the RSC

property with one (1) Area of Potential Environmental Concern. The Phase 2 ESA results of soil and

groundwater sampling did not reveal the presence of any method group target contaminants in exceedance

of the applicable Site Condition Standards.


5

4.0 CSM FORMAT

As required, the conceptual site model consists of diagrams, cross-sections and figures as well as text and

tables presenting site history, environmental site assessment activities and results, and remediation efforts

and results. The information contained herein is obtained from site investigative and assessment work for

the RSC property from June-November 2015.

5.1.1 APEC-1: Operation of Dry Cleaning Equipment (where chemicals are used)

The off-site up-gradient operation of a former Dry Cleaning business along the east adjacent property

boundary had the potential to impact the soil and groundwater. Contaminants of concern include Volatile

Organic Compounds (VOC’s) as chlorinated solvents. The location of the former dry cleaning business

presented an off-site PCA-1 and on-site APEC-1.

6.0 PHYSICAL SETTING

6.1 Topography

Review of topographic map # 30M/3 and 30M/6, Google Earth data, and site survey information

indicated the site sloped north, northwest. The area of the site is generally flat lying with a slope of

approximately 1% northwest. The approximate mean elevation of the site is 180 masl. Figure 5 details

topographic contours of the study site.

6.2 Hydrogeological Characteristics

Surface water drainage on-site was via runoff into the municipal storm sewer system. Site

hydrogeological conditions were identified regarding the unconfined, ‘water table’ regime via monitoring

wells MW-1, MW-2 and MW-3. Depths to groundwater were measured at 3.6-3.7 metres below ground

surface. The groundwater flow direction was calculated from survey data as northwest, with hydraulic

gradient of i = 0.01 based on the groundwater elevation survey.

6.3 Geology

Review of map: Quaternary Geology of Niagara-Welland (Ontario Geological Survey Map 2556),

indicated that the native overburden underlying the subject site was: Glaciolacustrine basin and quiet

water deposits of Silt & Clay as confirmed on site during borehole drilling, to depths exceeding 6 metres.

Depth to groundwater was measured at 3.6 metres below ground surfaces. Figure 6 provides N-S and E-

W cross sections of the study site.

6.4 Approximate Depth to Bedrock

Depth to bedrock at the RSC property was greater than 6 metres and not encountered during site

investigation. Regional well records indicated approximate depth to bedrock ranged from 36-42 m bgs.

6.5 Any Respect in which section 41 or 43.1 of the Regulation Apply

The RSC property is not located within what O.Reg 153/04 section 41 and 43.1 constitute as an

environmentally sensitive area or “if the property includes or is adjacent to a water body or includes land

that is within 30 metres of a water body”. The overburden at the RSC property is greater than 2.0 m in

depth and therefore does not constitute what is called a “shallow soil property”. Additionally, the soil pH

at the property fell within the acceptable range of 5 to 9, with Hallex’s samples indicating a pH of 6.94.

6.6 Areas Where Soil has been brought from another property

No soil has been brought to the RSC property originating from another property, during the ESA process.

6.7 Locations of Proposed Buildings or other structures

The location of the building will remain the same (see Figure 1). No proposed renovations to the existing

building structure other than interior renovations exist.

7.0 CONTAMINANTS

7.1 Each area where contaminants exceed applicable site condition standards

Following the Phase 2 soil and groundwater ESA investigation it was confirmed the APEC area

(identified above in Sections 3.0 and 5.1) did not exhibit any exceedance for contaminants of concern:

VOC’s vs. Table 2 Generic Full Depth Site Condition Standards for Residential Land Use in a Potable

Ground Water Situation, coarse.

7.2 Each Medium in Which a Contaminant is Present

No contaminants were identified in the mediums soil and/or groundwater.

7.3 Vapour intrusion of contaminants into buildings

Given the current conditions of the site, the potential for vapour intrusion into planned structures is

negligible, as VOC’s were not encountered during field screening, nor in soil and groundwater samples.

7.4 Subsurface Structure or Utilities that may affect Contaminant Distribution and Transport

No target contaminants were identified therefore the potential for underground utilities to affect

contaminant distribution and transport was negligible.

8.0 RECEPTOR EXPOSURE TO CONTAMINANTS

Since no contaminants were identified, there did not exist a potential for exposure to human and/or

ecological receptors.

9.0 CONCLUSIONS

The Phase 1 & 2 ESA investigations at the RSC property revealed one (1) PCA resulting in one (1) APEC

on the RSC property. Contaminants of Concern in soil and groundwater were assessed, with analytical

results indicating all MOE criteria was met for target contaminant VOC’s. Hallex therefore concludes

that the soil and groundwater site conditions satisfy MOE SCS Table 2 Residential Land Use criteria

(2011). The subject site is considered suitable for change to residential land use, within the definition of

O. Reg. 153/04 and 511/09 as of November 16th, 2015. No further environmental site assessment work is

considered necessary and the site conditions justify filing a record of site condition for residential land

use.
