Dear Ms. Ferri:

Re: Hydrogeological Assessment – Location of Water Table Teedon Pit Extension, North 1/2 of Lot 80, Concession 1, W.P.R and Part of the original road allowance between Lot 80 & 81, Concession 1, W.P.R, Geographic Township of Tiny, County of Simcoe, Ontario

1. Introduction

As requested, GHD has prepared the following hydrogeological assessment with regards to the location of the water table at the Cedarhurst Quarries and Crushing Ltd (Cedarhurst) Teedon Pit Extension located on the North 1/2 of Lot 80, Concession 1, W.P.R and Part of the original road allowance between Lot 80 & 81, Concession 1, W.P.R, Geographic Township of Tiny, County of Simcoe, Ontario. CRH Canada Group Inc. is the owner of the subject lands and has assumed responsibility for the approval of the Teedon Pit Extension on behalf of Cedarhurst.

The purpose of this report is to update the Alpha Environmental Services Inc. (AES) Hydrogeological Assessment dated April 12, 2011 following the installation of eight additional monitoring wells.

2. Background Information

2.1 Water Resources

In March 2012, Cedarhurst Quarries and Crushing Ltd. submitted a Township of Tiny Official Plan Amendment and Zoning By-law Amendment and a Ministry of Natural Resources and Forestry (MNRF) Class A Category 3 pit application to permit an extension to the existing Teedon Pit. The subject lands are located on the North 1/2 of Lot 80, Concession 1, W.P.R and Part of the original road allowance between Lot 80 & 81, Concession 1, W.P.R, Geographic Township of Tiny, County of Simcoe.

The original report to establish the water table was completed by AES. This report was reviewed by R.J. Burnside on behalf of the Township and R.J. Burnside signed-off on the application on November 19, 2014.

In May 2017, CRH Canada Group Inc. acquired the existing Teedon Pit and the Teedon Pit Extension lands. CRH retained GHD to install additional monitoring wells and complete additional site investigations to supplement the water resources information prepared by AES. As part of this work GHD also installed pressure transducers in all the existing Teedon Pit and proposed Teedon Pit Extension monitoring wells.

2.2 Geology and Hydrogeology of the Area

The Teedon Pit Extension is located within the Simcoe Uplands physiographic region where the topography varies significantly. The most common glacial features are sand plains, till plains and clay plains. This is regionally mapped as the Alliston Aquifer Complex.

The topography varies from approximately 260 to about 300 metres (m) above mean sea level (AMSL) (a northwest trending topographic high area) at the centre of the property.

Darby Road and Highway 93 border the east, Stamp Side Road the north, Marshall Road and Carpenter Side Road the west and the existing Teedon Pit is along the south border of the Teedon Pit Extension, as shown on Figure 1.

A small dugout pond is located on the northcentral part of the existing Teedon Pit.

A wetland also occurs to the north (downstream) of the dugout pond and is underlain by fine grained deposits.

In terms of geology and hydrogeology, the most significant deposits are sand deposits of the Upper Aquifer and fine grained deposits (silt and clay) of the Local Aquitard. The geologic and hydrogeologic framework is shown on the hydrogeologic cross-section A-A' (west-east) and cross-section B-B' (south-north) provided on Figures 2 and 3, respectively.

Groundwater flow is generally to the west in the Upper Aquifer from about 238 to 234 m AMSL, as shown on Figure 4.

The Local Aquitard is part of the Thorncliffe silt and clay deposits. The silt and clay deposits are not continuous and occur only on the eastern portion of the existing Teedon Pit and east of the Teedon Pit Extension on additional lands owned by CRH.

The Upper Aquifer is comprised of glacial lake sand with variable amounts of gravel and silt.

The Upper Aquifer is generally the source of water supply for the nearby domestic wells and for the aggregate washing operations within the existing Teedon Pit. There is no aggregate washing proposed within the Teedon Pit Extension.

3. Alpha Environmental Services Inc. Hydrogeological Assessment

The proposed Teedon Pit Extension licence application is for an Aggregate Resources Act (ARA) Class A, Category 3 Pit. Extraction is not proposed within 1.5 m of the established water table.

11155365Ferri-1 2

The original Site Plans for the Teedon Pit Extension included a much larger licensed area and were generated using a letter of opinion/ hydrogeological assessment prepared by Alpha Environmental Services Inc. (AES) dated April 12, 2011. AES determined the following with regards to the water table:

The water table is estimated to vary from 236.0 metres a.s.l. in the west portion of the licensed property to 254.8 meters a.s.l. on the central portion and to 252.2 meters a.s.l. in the east portion of the licensed property.

The AES Assessment was based on four Monitoring wells (MW1-09, 16440 [decommissioned], MW1, and MW4) located at the Teedon Pit and an adjacent domestic well (25425). AES used water table elevation data from these wells to establish the water table for the Teedon Pit Extension lands. Only one monitoring well (MW1-09) was located on the Teedon Pit Extension property at the time.

4. Additional Monitoring Well Installations

Eight additional monitoring wells (MW5-18, MW6R-18, MW6-18, MW7-18, MW8-18, MW9-18, MW10-18S, and MW10-18D) were installed at the Teedon Pit in 2018 to better characterize the subsurface hydrogeological conditions and to allow additional monitoring of the water table. The monitoring well completion details are provided in Table 1.

The new monitoring wells installed on the Teedon Pit Extension property are MW8-18, MW9-18, MW10-18S, and MW10-18D.

The location of all monitoring wells are provided on Figure 1.

5. Proposed Teedon Pit Extension

In accordance with Provincial requirements for a Class A, Category 3 Pit licence extraction will take place 1.5 m above the established water table. The area proposed to be licensed is 15.3 hectares of which 13.5 hectares are proposed to be extracted. The proposed licensed boundary and limit of extraction are illustrated on Figure 1.

6. Water Table Assessment

Currently there are a total of 12 wells that are monitored on the Teedon Pit and Extension properties. There is one pumping well (PW1-09) and 11 monitoring wells (MW1, MW1-09, MW4-10, MW5-18, MW6-18, MW6R-18, MW7-18, MW8-18, MW9-18, MW10-18S, and MW10-18D). In addition, there are three domestic wells (#50632, #25425, and #17709) that have been historically monitored.

Groundwater elevation data has been collected both manually and automatically with pressure transducers/dataloggers at the monitoring well and domestic well locations since approximately 2009 and since 2018 for the newly installed monitoring wells. The manual and pressure transducer data were

11155365Ferri-1 3

reviewed and are very similar. The maximum observed groundwater elevation for each of the monitoring locations is provided in Table 2. In reviewing water levels at the additional monitoring wells installed on the Teedon Pit Extension lands it has been confirmed that the water table in the centre of the subject lands is much lower than originally indicated by AES. Consequently, the water table varies between 236.0 m AMSL on the west side of the proposed licensed boundary to 237.8 m AMSL at the eastern licensed boundary. The maximum observed groundwater elevation is shown on Figure 5.

A local zone of saturation exists above the water table where the relatively impervious Local Aquitard interrupts/intercepts percolation causing groundwater saturation. See Figures 2 and 3 for the location of the local aquitard. This is not considered the water table for the purpose of establishing the on-Site water table due to its isolated nature and limited function. There are no water supply wells drawing water from this unit that may be influenced. The unevaluated wetland area downstream of the dugout pond will not be affected by the proposed extraction of sand and gravel, and it is more than 100 m from the proposed extraction area1.

7. Assessment

Since extraction will remain 1.5 m above the established groundwater table, there will be no impact to private wells or groundwater resources.

8. Recommendations

1. In order to confirm that the maximum depth of extraction for the Teedon Pit Extension is no closer than 1.5 m above the established ground water table the water levels at monitoring wells MW1-09, MW8-18, MW10D-18, and MW5-18 shall be monitored quarterly and the water level at monitoring well MW9-18 shall be monitored quarterly until it is removed for extraction. 2. The water level measurements shall be compared to the maximum depth of extraction on the site plans. In the event the water level data indicates the maximum depth of extraction is less than 1.5 m above the established groundwater table, the maximum depth of extraction shall be adjusted accordingly to maintain the 1.5-m depth. 3. The operator shall maintain a record of the ground water levels to confirm the maximum depth of extraction remains 1.5 m above the established water table. 4. The ARA site plans shall identify the pit floor as 1.5 m above the established water table elevations based on groundwater contours shown on Figure 5.
