1.0 INTRODUCTION Golder Associates Ltd. (Golder) was retained by QBJR/Coco Aggregates Inc. (Coco) to prepare a quarterly compliance report for the McCarthy Quarry located in the Township of Ramara, County of Simcoe (Figure 1). The Environmental Compliance Approval (ECA) No. 4731-987KM8 issued on October 15, 2013 requires this task. A copy of the ECA No. 4731-987KM8 is found in Appendix A.

The following report addresses the requirements described in Sections 7 and 8 of the ECA. Included herein are a brief background, summary and discussion of the sampling results and data collected on-site during each sampling event.

2.0 BACKGROUND The McCarthy Quarry dewatering system consists of the collection of groundwater and surface water (hereafter referred to as “quarry discharge”) at the base of the quarry floor in a quarry sump which is pumped to a settling pond, at grade, to the south of the active quarry area (Figure 1). The sump is equipped with a 4-inch Grindex pump which is rated at 35 L/sec and is attached to a 4-inch (101 mm) diameter discharge line. Water is pumped from the quarry floor up the quarry face to a 4-inch (101 mm) diameter pipeline that directs the water to the 14,000 m3 settling pond. The water in the settling pond is equipped with a Hickenbottom control structure that discharges the water to the roadside ditch along Concession Road 1. The water flows eastward along the north side of Concession Road 1 to a municipal drain and eventually to the Talbot River, which discharges into Lake Simcoe.

The dewatering activities from the McCarthy Quarry are currently carried out under the existing ECA No. 4731-987KM8 issued on October 15, 2013. Under the current ECA Coco is permitted to pump water from the quarry sump at a rate of 4,545 L/min (76 L/sec).

3.0 QUARRY DISCHARGE MONITORING PLAN Weekly monitoring of the effluent is required by the ECA at three locations, as shown on Figure 1:

The outfall of the settling pond (labelled as McCarthy Pond);

The culvert along Concession Road 1 at the McCarthy property (SW1) downstream of the McCarthy Pond discharge location; and,

260 m north of the intersection of Concession Road 1 and the Mara Eldon Boundary Road (labelled as SW2) representing upstream conditions.

Weekly quarry discharge monitoring is required per Section 7(2) for Total Suspended Solids (TSS), Oil and Grease, Phenolics (4AAP) and pH at the McCarthy Pond. Additional water quality sampling is required under Section 7(3) at a semi-annual frequency at all three locations, recognizing that, as of April 24, 2014 this monitoring was reduced from weekly sampling frequency to a semi-annual frequency following one year of quarry operation according to Section 7(7). The parameters required for semi-annual water quality monitoring at all three locations are listed in Table 3 of the ECA. Monthly acute lethality is also required at the McCarthy Pond under Section 8.

As per Section 7(8) an inline flow meter is installed in the discharge line of the sump pump in order to measure continuous flow rates. The flow rates are recorded and provided to Golder by staff at McCarthy Quarry.

The weekly quarry discharge samples (Section 7(2)) were collected by staff at the McCarthy Quarry. The semi-annual water quality samples (Section 7(3) and Section 7(7)) were collected by Golder. Both the weekly and semi-annual water quality samples were sent to Maxxam Analytics Laboratory for analysis. Additionally, the monthly lethality samples were collected by Golder and sent to AGAT Laboratories Ltd.

The weekly water quality sample was not collected from the McCarthy Pond on the weeks of July 30 to August 3, September 3 to 7, September 10 to 14, September 17 to 21, September 24 to 28, October 1 to 5, October 8 to 12, October 15 to 19 and October 22 to 26, 2018 as quarry staff reported there was no discharge at the time of sampling. In addition, the monthly lethality sample was not collected from the McCarthy Pond during the months of September and October 2018 as there was no quarry discharge at the time of sampling.

4.0 QUARRY DISCHARGE MONITORING RESULTS All laboratory certificates of analysis for the August to November 2018 monitoring period are included in Appendix B. Results of the quarry discharge monitoring are summarized below:

The TSS, pH, Oil and Grease and Phenol (4AAP) concentrations were all below the daily concentration limits of the ECA (Table 1);

The TSS, Oil and Grease and Phenol (4AAP) concentrations were all below the monthly concentration limits of the ECA (Table 2);

The semi-annual surface water sampling results were below the PWQO, with the exception of phosphorus and iron at SW1 and phosphorus at SW1 (Table 3);

The quarry discharge between August and November, 2018 was found to be non-lethal to rainbow trout and Daphnia magna (Table 4). Zero rainbow trout and zero Daphnia died during lethality testing during the past quarter; and,

The discharge rate between August and November, 2018 was below the permitted rate of 4,545 L/min (76 L/sec) (Table 5).

5.0 SUMMARY AND RECOMMENDATIONS All samples met the daily and monthly concentration limits of the ECA No. 4731-987KM8.

1. Provincial Water Quality Objectives (PWQO); shaded cells denote PWQO exceedance;

some PWQOs are dependent on other water quality parameters hence the range in guideline

values, refer to PWQO notes.

2. Interim Provincial Water Quality Objectives (Interim PWQO); shaded cells and italics

denote Interim PWQO exceedance ; some PWQOs are dependent on other water quality

parameters hence the range in guideline values, refer to PQWO notes.

3. The PWQO for Oil and Grease indicates that oil or petrochemicals should not be present in

concentrations that: can be detected as a visible film, sheen or discolouration on the surface,

can be detected by odour, can cause tainting of edible organisms, can form detectable deposits

on shorelines and bottom sediments.

4. Results that are preceeded by "<" denote concentrations that are below the laboratory

Reportable Detection Limit (RDL).

5d. Cadmium:

(Interim)

5f. Copper:

(Interim)

5a. Aluminum (Interim):

- At pH 4.5 to 5.5 the Interim PWQO is 15 ug/L based on inorganic monomeric aluminum

measured in clay-free samples.

- At pH >5.5 to 6.5, no condition should be permitted which would increase the acid soluble

inorganic aluminum concentration in clay-free samples to more than 10% above natural

background concentrations for waters representative of that geological area of the Province

that are unaffected by man-made inputs.

- At pH >6.5 to 9.0, the Interim PWQO is 75 ug/L based on total aluminum measured in clay-

free samples.

- If natural background aluminum concentrations in water bodies unaffected by manmade inputs

are greater than the numerical Interim PWQO (above), no condition is permitted that would

increase the aluminum concentration in clay-free samples by more than 10% of the natural

background level.

- Current scientific evidence is insufficient to develop a

firm Objective at this time.

- Accordingly, the following phosphorus concentrations

should be considered as general guidelines which

should be supplemented by site-specific studies:

(a) To avoid nuisance concentrations of algae in lakes,

average total phosphorus concentrations for the ice-

free period should not exceed 20 ug/L;

(b) A high level of protection against aesthetic

deterioration will be provided by a total phosphorus

concentration for the ice-free period of 10 ug/L or less.

This should apply to all lakes naturally below this value;

(c) Excessive plant growth in rivers and streams should

be eliminated at a total phosphorus concentration

below 30 ug/L.

(1) Due to a high concentration of NOx, the sample required dilution. The detection limit was adjusted accordingly.

NC (Duplicate RPD): The duplicate RPD was not calculated. The concentration in the sample and/or duplicate was too low to permit a reliable RPD calculation (absolutedifference <= 2x RDL).

NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spike amountwas too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)
