INTRODUCTION

Golder Associates Ltd. (Golder) was retained by Scotian Materials (Scotian) to complete a series of hydrological field and desktop studies to support the Environmental Assessment Registration Document (EARD) for the Goffs Quarry Expansion Project (Project) located in the Halifax Regional Municipality (HRM). Golder understands that the Project proposed by Scotian consists of the construction, operation, decommissioning and reclamation of a construction aggregate quarry expansion located on a 100.3 ha property (PID 00505941) in Goffs, Nova Scotia (herein referred to as the Project). Scotian currently operates a 3.99 hectare (ha) quarry under an existing Industrial Approval (Approval No. 2016-095664), which was issued in June 2017. The Project will expand on the existing 3.99 ha quarry by approximately 40.79 ha, for a total area of 44.78 ha. The Project is on lands owned by Scotian located in Goffs, Halifax County, NS (PID 00505941) (herein referred to as the Property Boundary or Property). The purpose of this report is to characterize existing conditions and potential impacts on four un-named watercourses located within the Property Boundary (Streams 3, 4, 5, and 6), and one downgradient watercourse (Holland Brook), with respect to the following:

Aquatic environment;

Stream flows;

Surface water quality; and,

Catchment area and water balances. 1.0 EXISTING CONDITIONS

1.1 Aquatic Environment

The Project is located within the Miller Lake Tertiary Watershed which is approximately 4,356 ha in size. The Miller Lake Tertiary Watershed is located in the Shubenacadie/Stewiacke Primary Watershed and secondary Shudenacadie River Watershed. The outlet of the tertiary watershed drains into Lake Thomas.

There are six un-named streams on the Property (Figure 1). However, as stated above, this report focuses on Streams 3, 4, 5 and 6. Preeper’s Pond, is located approximately 115 m northeast of the Property and feeds Holland Brook. Holland Brook then flows southwest, approximately 120 m south of the Property Boundary, where it passes through an un-named lake/wetland referred to as “Horseshoe Wetland” and ultimately into Soldier Lake. Four of the six un-named streams on the Property flow into Holland Brook. An un-named lake (i.e. Horeshoe Wetland) is located approximately 200 m south of the Property. Stream 3

Stream 3 is the largest watercourse on the Property. Stream 3 drains from a small lake on the northwest side of Highway 102, flows under the highway via a culvert and enters the Property from the northwest (Figure 1). The stream then flows south into an off-site wetland. The majority of the reach of Stream 3 within the Property Boundary is shallow run and riffle habitat with moderate velocity due to the steep gradient change over the length of the reach. There are also some cascade sections in the mid to lower portion of the reach where the gradient changes more significantly. Substrates are coarse and consist predominantly of cobble with boulder and/or gravel. There is a short pool section just downstream of the culvert at Highway 102 with a maximum depth of approximately 0.55 m, as well as a shallow pool area with a depth of approximately 0.20 m in the mid-section of the reach created by an existing ATV trail that crosses the watercourse. There are limited, short lengths of flat channel in the upper and middle sections of Stream 3. The average wetted width is 3.5 m and average wetted depth is 0.15 m. Riparian vegetation is mixed forest with a moderately steep approach slope and the banks are generally stable. There is abundant woody debris providing instream and overhanging cover, especially in the lower section of the reach. Instream cover is also provided by coarse substrate. Stream 4

Stream 4 originates in Wetland 2 in the north-central portion of the Property and flows south to eventually empty into Stream 3 south of the Property Boundary (Figure 1). The reach of Stream 4 within the Property Boundary consists of headwater-type habitat, and is moderate to low velocity shallow runs for the length on the Property. The stream is shallow and narrow, with wetted width averaging 0.85 m and wetted depth averaging 0.15 m. The substrate is a mix of sand, silt, gravel, cobble, and boulder, with no one dominant type. One groundwater seep was observed approximately mid-way on the Property. Riparian vegetation is mixed forest with a moderately steep approach slope and the banks are generally stable. There is abundant woody debris providing instream and overhanging cover. The elevation change over the length of the reach of Stream 4 is fairly steep. This causes the channel to flow through and under alluvial bed materials in areas and water to drop steeply over woody debris and coarse substrate, causing potential barriers to fish passage. It was observed that water in the northern portion of the stream flowed underground beneath the surficial soil and roots and there were potential barriers (i.e. root wads and boulders) observed in the southern portion of the stream. Stream 5

Stream 5 is fully contained within the Project footprint and connects Wetlands 4 and 5 in the central portion of the Property (Figure 1). The aquatic habitat in Stream 5 is very similar to that observed in Stream 4, and consists of shallow runs over the length. The stream is shallow and narrow, with depth ranges averaging 0.09 m and wetted width averaging 1.0 m. The substrate is cobble/gravel with sparse boulder throughout. Riparian vegetation is

mixed forest, with a gradual approach slope and banks are generally stable with shallow undercutting in areas. There is abundant woody debris providing instream and overhanging cover. Several potential barriers to fish migration are present, created by root wads and woody debris piles, as well as the channel flowing underground beneath the surficial soil and roots in some areas. One inflowing tributary that originates as groundwater seepage was observed mid-way through the reach in the stream. There is no direct connection between Stream 5 and any other surface watercourses. However, during high flows, Stream 5/Wetland 4 flows along Perrin Drive and confluences with Stream 4. Stream 6

Stream 6 enters the northeast corner of the Property via a culvert under Highway 102, and flows through Wetland 7 (Figure 1). Stream 6 flows through a defined channel downstream of Wetland 7 adjacent to the Project and flows into Horseshoe Wetland south of the Property Boundary. The upstream portion of the reach of Stream 6 within the Property Boundary is headwater-type habitat consisting mostly of shallow runs with some limited areas of shallow pools, riffles and flats. Substrate is cobble/boulder with sporadic areas of gravel and silt. The downstream portion of the reach widens slightly and current velocity slows, creating flat habitat with abundant short sections of shallow runs. The substrate in the downstream portion was noted to be less coarse and more depositional, with silt/gravel dominating with cobble areas. Riparian vegetation is mixed forest, with a gradual approach slope. Banks are generally stable with shallow undercutting in areas. There is abundant woody debris providing instream and overhanging cover for fish refuge. Holland Brook

Holland Brook is located southwest of Preeper’s Pond south of the Property Boundary, in the study area (Figure 1). The upper portion of the reach flows through a marshy wetland west of the outlet from Preeper’s Pond and continues southwest through the “Horseshoe Wetland” in the southwest corner of the study area. Four of the un-named streams on the Property flow into Holland Brook (Streams 3, 4&5, 6). Stream 6 flows into Horseshoe Wetland while Streams 3, 4 and 5 confluence further south with the brook. During surveys, it was noted that this watercourse had moderate flow with a mix of riffles, pools and runs. Substrate is cobble/sand/gravel over bedrock, and banks were generally stable. The stream is shallow, with wetted depth averaging 0.15 m and wetted width averaging 2.0 m, with some occasional deeper pools. Riparian vegetation is mixed forest providing moderate canopy cover and with a moderate approach slope. No barriers to fish movement along Holland Brook and in/out of Prepper’s Pond were observed. 1.2 Stream Flows

1.2.1 Methodology

Water levels and flows were monitored at 12 locations between February 2017 and February 2018: two locations in Stream 4 (SW1 and SW2), two in Stream 5 (SW3 and SW4), two in Stream 6 (SW5 and SW6), two in Stream 3 (SW7 and SW8), and four in Holland Brook (SW9, SW10, SW11, SW12). The types of monitoring carried out at each location consisted of the following:

Surface water level monitoring: A staff gauge was installed and used for manual surface water level measurements during field visits. The staff gauge was geodetically surveyed in order to establish a water level elevation.


4

Continuous water level monitoring: A water level transducer and datalogger (level logger) was installed at each location to measure surface water levels at specified intervals.

Flow monitoring: Instantaneous flow measurements were recorded during field visits. Flow measurements were collected using conventional current meter equipment (Hach FH950) in accordance with standard practice. Flow measurements were collected using the velocity-area technique where stream flow is computed as the product of the cross-sectional area and the average velocity. Observations of velocities were made at 0.6 of the depth below the water surface. The flow was calculated by averaging the results of the mean and midsection flow calculation method. 1.2.2 Results

Fourteen monitoring events were carried out between February 3, 2017 and February 7, 2018, capturing wet and dry conditions. The water levels at the staff gauges were measured manually during the monitoring visits and are presented in Tables A.1 through A.5 in Appendix A. The water levels and continuous water level monitoring data were used to create a water level hydrograph for each station, as presented in Figures A.1 to A.12 (Appendix A). The measured flows for all locations and monitoring events, along with the weather conditions observed during each monitoring event, are presented in Tables A.1 through A.5 in Appendix A. 1.2.3 Discussion

The monitored flows in all streams were within expected seasonal variations with low flows during the summer months and high flows during the spring freshet. The flow measurements obtained during the spring (following the freshet) were similar to the flow measurements taken in the fall for all streams. Construction activities for the less than four hectare quarry commenced in September 2017 resulting in four flow monitoring events being conducted as part of the construction phase monitoring. The flows and water levels measured from September to November were similar to flows and levels measured earlier in the year under baseline conditions. One flow measurement (December 2017) was obtained following the first blast event (November 21, 2017). The December 8, 2017 flow measurements in Stream 5 were taken during a discharge event. It should be noted that monitoring location SW4 (Stream 5 downstream) is located upstream of the overland discharge confluence with Wetland 4. Therefore, monitoring location SW4 represents the flow of Stream 5 upstream of Wetland 4. During the January 2018 flow monitoring event the streams were frozen and flow measurements could not be obtained in a safe and accurate manner. As shown on the water level hydrographs the streams are responsive to rainfall and snowmelt events, represented by the peaks of water level increase. The measured water levels throughout the year followed a typical trend of higher levels in the spring (during the spring freshet) and lower water levels in the summer months. The manual water level readings in the winter were affected by ice conditions. Stream 3

Water level and flow monitoring was conducted in Stream 3 from July 2017 to February 2018. The flows in Stream 3 generally increased from upstream to downstream. Stream 4


5

Water level and flow monitoring was conducted in Stream 4 from February 2017 to February 2018. The flows in Stream 4 generally increased from upstream to downstream. Stream 5

Water level and flow monitoring was conducted in Stream 5 from February 2017 to February 2018. The measured flows in Stream 5 were typically the same at both the upstream and downstream locations with the exception of measurements taken during and following large rainfall events and the spring freshet. During three monitoring events (March 2, August 15 and December 8) the flow measurements at the upstream location were larger than the downstream location. Flows at Stream 5 vary throughout the year and monitoring will continue in order to further improve our understanding of this stream. Stream 6

Water level and flow monitoring was conducted in Stream 6 from March 2017 to February 2018. The flows in Stream 6 generally increased from upstream to downstream. Holland Brook

Water level and flow monitoring was conducted in Holland Brook from August 2017 to December 2017. The flows in Holland Brook generally increased from upstream to downstream; however, flows generally decrease between stations SW10 and SW11 as Holland Brook passes through an un-named lake/wetland referred to as “Horseshoe Wetland”. 1.3 Surface Water Quality

Surface water quality samples were obtained from upstream and downstream locations in Streams 3, 4, 5, 6, and Holland Brook (Figure 2). Water quality samples were collected in Streams 3 and 6 in July 2017, in Holland Brook in August 2017, and in Streams 4 and 5 between May 2016 and January 2018. 1.3.1 Methodology

Surface water quality samples were submitted under chain of custody to Maxxam Analytics and to AGAT Laboratories in NS and the certificates of analyses are attached in Appendix C. These samples were analyzed for a general suite of inorganics, total metals, and petroleum hydrocarbons (PHCs). In-situ field measurements for pH, conductivity and total dissolved solids (TDS) were also taken at each location. Standard sampling protocols were followed to ensure accuracy and precision of results. This included decontamination procedures, the collection of QA/QC samples, labelling, preserving, completed Chain of Custody forms, and packaging QA/QC procedures in the laboratory. QA/QC sampling was conducted on approximately 10% of samples that were analyzed. Field QA/QC was addressed by collecting blind field duplicates. The results of this testing were used to evaluate the reliability of the sampling and analysis methods. 1.3.2 Results

Surface water quality results were compared to the Canadian Council of Ministers of the Environment (CCME) Fresh Water Aquatic Life Guidelines. In addition, if the upstream water quality was above the CCME guidelines, the downstream sample was compared to the upstream sample concentration. The surface water quality results and QA/QC results are included in Tables B.1 to B.3 in Appendix B and summarized below. Field measurements for pH, conductivity, TDS, and temperature are presented in Table B.4.

Stream 3

Total aluminum, and total iron concentrations were greater than CCME guidelines at the upstream water quality monitoring station in July 2017. The total iron concentration also exceeded CCME guidelines at the downstream station. All exceeding parameters were greater in the upstream sample compared to the downstream sample.

There were no exceedances of general chemistry parameters in Stream 3.

PHCs were not detected in samples taken from Stream 3. Stream 4

Dissolved chloride, total aluminum, total cadmium, total copper, total iron, and total lead concentrations were greater than CCME guidelines at the upstream water quality monitoring station in May 2016. The May 2016 water quality is representative of baseline conditions.

Total aluminum, total copper, total iron, and total lead concentrations were greater than CCME guidelines at the upstream and downstream water quality monitoring station in September 2017. Total cadmium concentrations were greater than the CCME guidelines at the upstream water quality station. Concentrations of total aluminum and total cadmium were greater in the upstream sample compared to the downstream sample. Total copper, total iron, and total lead were greater in the downstream sample than in the corresponding upstream sample. This sampling event was initiated by construction activities at the less than four hectare quarry. However, Stream 4 does not receive quarry discharge and therefore this sampling round was considered as baseline monitoring.

All parameters during the January 2018 water quality monitoring event, at both upstream and downstream locations, were below the CCME guidelines. Total selenium was greater than CCME guidelines in the downstream duplicate sample in January 2018 at 2 ug/L. However, the Stream 4 downstream sample was less than the detection limit (< 1ug/L) and the CCME guidelines. This sampling event occurred after the blasting activities in November 2017. However, Stream 4 does not receive quarry discharge and therefore this sampling round was considered as baseline monitoring.

With the exception of dissolved chloride, there were no exceedances of general chemistry parameters in Stream 4.


Total aluminum, total cadmium, total iron, and total lead concentrations were greater than CCME guidelines at the downstream water quality monitoring station in May 2016. The May 2016 water quality is representative of baseline conditions.

Total copper was greater than CCME guidelines in September 2017 at the upstream and downstream water quality monitoring stations. This sampling event was initiated by current quarry activities and is considered part of the monitoring required during the construction phase.


7

Total aluminum concentrations were greater than CCME guidelines at the upstream and downstream water quality monitoring stations in January 2018. The total aluminium concentration in the corresponding downstream sample was greater than the upstream sample concentration. Total selenium concentrations at the upstream location were greater than the CCME guidelines in January 2018. However, the total selenium concentrations at the downstream water quality monitoring station were below the detection limit. This sampling event occurred after the blasting activities in November 2017 and is considered part of the monitoring required during the construction phase for the less than four hectare quarry.



Total aluminum, total iron, and total lead concentrations were greater than CCME guidelines at the upstream water quality monitoring station in July 2017. The total aluminum concentration also exceeded CCME guidelines at the downstream station. All exceeding parameters were greater in the upstream sample compared to the downstream sample.


PHCs were not detected in samples taken from Stream 6. Holland Brook

Total iron and mercury concentrations were greater than CCME guidelines at the upstream water quality monitoring station (SW9) in August 2017. Total iron and mercury concentrations also exceeded CCME guidelines at the downstream station (SW12). All exceeding parameters were greater in the upstream sample compared to the downstream sample.

PHCs were not detected in samples taken from Holland Brook. QA/QC

During each monitoring event 10% of the total number of surface water samples were collected for QA/QC purposes. One field duplicate sample was collected in 2017 and analysed for general chemistry and total metals. These 2017 duplicate sample results have a Relative Percent Difference (RPD) from the original sample that ranges from 0 to 18%. This is an acceptable margin of error for field and lab method reproducibility for surface water samples.

1.3.3 Discussion

Given the location of the existing quarry activities, the results of the water quality samples obtained from 2016 to 2018 are representative of background conditions. The September 2017 and January 2018 results for Streams 4 and 5 are considered to be a part of the construction monitoring phase for the less than four hectare quarry and are consistent with the baseline water quality obtained in May 2016. It should be noted for the January 2018 sampling event, the streams were frozen preventing completion of flow measurements; however, there was sufficient flowing water to collect water quality samples. The water quality parameters that exceeded the CCME guidelines in January 2018 are naturally present at the Property and are consistent with the baseline water quality.

1.4 Hydrologic Water Balance

A water balance assessment was carried out to assess the potential hydrological impacts of the proposed expansion with respect to post-development (i.e., full development of the proposed Goffs quarry) runoff and infiltration rates. Streams 4, 5 and 6 were assessed due to post-development changes in the drainage areas contributing to these features. Stream 3 was not assessed from a water balance perspective since the drainage area for this feature will not change due to extraction. Please note that the calculations presented in this section do not include the estimated groundwater seepage component. 1.4.1 Methodology

The water balance assessment was based on meteorological data obtained from Environment Canada (“EC”) from the Halifax International Airport Meteorological Station (ID 8202251) from 1961 to 2015, information on current and proposed land uses as provided to Golder, and existing soil types as identified through the subsurface investigation activities within the Property Boundary. Meteorological data used in the assessment is summarized in Table D.1 in Appendix D. Water balance calculations are based on the following equation, which is described in more detail below:

P = S + ET + R + I Where: P = precipitation; S = change in soil water storage; ET = evapotranspiration; R = surface runoff; and I = infiltration (groundwater recharge). Precipitation data obtained from EC for the Halifax Intl A station indicate a mean annual precipitation (“P”) of 1453 mm/yr. Short-term or seasonal changes in soil water storage (“S”) are anticipated to occur on an annual basis as demonstrated by the typically dry conditions in the summer months and the wet conditions in the winter and spring. Long-term changes (e.g. year to- year) in soil water storage are considered to be negligible in this assessment. Evapotranspiration (“ET”) refers to water lost to the atmosphere from vegetated surfaces. The term combines evaporation (i.e., water lost from soil or water surfaces) and transpiration (i.e., water lost from plants and trees). Potential ET refers to the loss of water from a vegetated surface to the atmosphere under conditions of an unlimited water supply. The actual rate of ET is typically less than the potential rate under dry conditions (e.g., during the summer months when there is a moisture deficit). The mean annual potential ET for the study area is approximately 568 mm/yr based on data provided by EC. The mean annual water surplus is the difference between P and the actual ET. The water surplus represents the total amount of water available for either surface runoff (“R”) or groundwater infiltration (“I”) on an annual basis. On a monthly basis, surplus water remains after actual evapotranspiration has been removed from the sum of rainfall and snow-melt, and maximum soil or snow pack storage is exceeded. Maximum soil storage is quantified using a water holding capacity (“WHC”) specific to the soil type and land use.


9

Infiltration rates were estimated using the method presented in the Ontario Ministry of the Environment (“MOE”) Stormwater Management Planning and Design (“SWM”) Manual (MOE, 2003). There are three main factors that determine the percent infiltration of the water surplus: topography, soil type and ground cover. The sum of the fractions representing these three factors establishes the approximate annual percentage of surplus which can be infiltrated in an area with a sufficient downward groundwater gradient. Wetlands and water bodies are assumed to have an upward or negligible downward gradient, resulting in all surpluses being contained in these areas, which provide increased evaporation and typically limited infiltration. Land use within the Project under existing conditions was identified from a topographical survey plan provided by Scotian. Land use within the Project under post-development conditions was based on the planned Project layout provided by Scotian. The land use data were compiled to estimate the total area (in m2) of each land use within the Property Boundary. Data and provided information from this investigation were used with Table 3.1: Hydrologic Cycle Component Values, from the MOE SWM Manual (MOE, 2003), to identify appropriate WHCs and to sum an infiltration factor for each land use. 1.4.2 Water Balance Parameters

1.4.2.1 Drainage Catchments

The Project is located in the southern end of the Miller Lake tertiary watershed before draining into Soldier Lake as part of the regional Shubenacadie River watershed. Catchments were delineated to reflect the changes in land-use and corresponding water balance characteristics associated with the pre-development and post-development conditions, using available site mapping provided by Scotian. To evaluate the potential effects of the development of the Goffs Quarry, three streams and one wetland were selected for the assessment (Figures 2 and 3). Catchments are outlined as follows:

Stream 4 (pre-development condition): Approximately 27 ha, represents the drainage area of Stream 4 to the southwest property boundary.

Stream 5 (pre-development condition): Approximately 24.1 ha, represents the drainage area of Stream 5 when it joins Stream 4 near the southwest property boundary. This catchment includes the existing quarry area.

Wetland 7 (unchanged): Approximately 25.9 ha, represents a local drainage area contributing to Wetland 7.

Stream 6 (pre-development condition): Approximately 49.2 ha, represents the drainage area of Stream 6 to the southeast property boundary. This catchment is inclusive of the Wetland 7 catchment area.

Stream 4 (post -development condition): Approximately 54.4 ha, represents the drainage area of Stream 4 to the southwest property boundary in post-development condition. This catchment includes the Stream 5 catchment which will be removed during the expansion of the quarry (phases 1 to 3 of the proposed expansion, Figure 3).

Stream 6 (post -development condition): Approximately 44.8 ha, represents the drainage area of Stream 6 to the southeast property boundary. This catchment includes phase 4 of the proposed expansion.

1.4.2.2 Infiltration and Runoff

Based on the results of subsurface investigation activities within the Project, the surficial soil type was identified as silty sand. As a result, the soils were modelled as fine sand to fine sandy loam in this assessment. Based on the borehole information collected within the Property Boundary, the overburden thickness ranges between 0.0 m (i.e. bedrock at surface) and 0.48 m. Over large areas of the Property the overburden thickness was insufficient to use the recommended water holding capacities. Therefore, the water holding capacities were reduced proportionally based on the average overburden thickness across the Property. Based on available topography and the grading plan for the Project, a topography factor of 0.1, representing hilly land with an average slope of 28 m to 47 m/km (2.8% to 3.8%), was applied for the pre-and post-development conditions. Due to the shallow overburden thickness an infiltration factor of 0.2 was assigned for the soil factor. For the cleared areas (i.e. cleared, stripped, and grubbed) areas a soil factor of 0.1 was assigned. Tree-covered areas were assigned a cover factor of 0.2, representing woodland. Grass-covered and cleared areas were assigned a cover factor of 0.1, representing cultivated land. A coefficient of 0 (indicating no infiltration) was applied to the proposed extraction area (i.e., quarry) and the wetlands. The infiltration coefficient of 0 applied to the extraction area was used to acknowledge the likelihood that upward groundwater gradient into the quarry will effectively prevent infiltration in the dewatered excavation. The infiltration coefficient of 0 applied to the wetland areas was used to acknowledge that typically, upward or small downward groundwater gradients occur in wetland areas minimizing infiltration and increasing evaporation. This information was used with Table 3.1: Hydrologic Cycle Component Values (MOE 2003), to identify appropriate the WHC and a corresponding infiltration factor for each land use. Infiltration factors and WHCs for each land use are summarized in Table 1. Table 1: Estimated WHC and Infiltration Factors

Net surplus was estimated by multiplying the estimated monthly surplus (mm/month) for the assumed WHC by the associated drainage area. Annual evapotranspiration and surplus values were obtained from the meteorological data from the Halifax International Airport Meteorological Station EC Meteorological Station based on the WHC assigned to each land use area.

Runoff was calculated as the difference between surplus and infiltration. 1.4.3 Water Balance Results

The following sections present the annual average water balance analysis under the pre-development and post-development conditions. Detailed water balance tables are provided in Appendix D. The catchment areas used for the assessment are shown in Figures 2 (pre-development) and 3 (post-development). 1.4.3.1 Stream 4 and 5

Under pre-development conditions (Figure 2) Stream 5 confluences with Stream 4 upstream of the Property Boundary. Therefore, the pre-development assessment for Stream 4 at the Property Boundary includes the drainage area of Stream 5. As shown in Figure 3, the catchment contributing to Stream 4 will be decreased in the post-development condition and Stream 5 will be removed. As a part of the quarry water management system, water from the sediment pond, which will include the quarry seepage, will be discharged/returned to Stream 4. Please note that the calculations presented in this section do not include the estimated groundwater seepage component. Results of the average annual water balance for Stream 4 at the property boundary are presented in Table 2. Table 2: Stream 4 at the Property Boundary Average Annual Water Balance Results

Note: (1) Catchment is within the expected radius of influence on groundwater; therefore, it is assumed the infiltration component will become part of the groundwater inflow to the quarry.

In the post-development condition, the total estimated average annual surplus to Stream 4 is 510,030 m3 and the estimated average annual runoff to Stream 4 is approximately 401,620 m3. Surplus increased by approximately 11% and runoff increased by approximately 48% compared to pre-development conditions. The monthly water balance results under post-development conditions are included in Tables D.2 and D.3 in Appendix D.

1.4.3.2 Wetland 7

The catchment contributing to Wetland 7 will not be changed by the quarry expansion. Therefore, the water balance results for the post-development condition will be the same as the pre-development condition. Table 3 presents the results of the average annual water balance for Wetland 7. Table 3: Wetland 7 Average Annual Water Balance Results

The total estimated average annual surplus to Wetland 7 is 231,590 m3 and the estimated average annual runoff to Wetland 7 is approximately 120,800 m3. The monthly water balance results are included in Table D.4 in Appendix D. 1.4.3.3 Stream 6

The pre-development drainage area is shown on Figure 2. As shown in Figure 3, the catchment contributing to Stream 6 will be decreased in the post-development condition. As a part of the quarry water management system, water will be discharged/returned to Stream 6 near the southeast property boundary. Results of the average annual water balance for Stream 6 at the property boundary are presented in Table 4. Table 4: Stream 6 Average Annual Water Balance Results

In the post-development condition, the total estimated average annual surplus to Stream 6 is 408,320 m3 and the estimated average annual runoff to Stream 6 is approximately 257,330 m3. Surplus decreased by 7% and runoff increased by 14% compared to pre-development conditions. The monthly water balance results under post-development conditions are included in Tables D.5 and D.6 in Appendix D. 2.0 POTENTIAL EFFECTS & MITIGATION

If left unmanaged, potential effects of the proposed Project could include degradation of water quality from suspended sediment as well as decrease/increase in water quantity in the wetlands and watercourses. Changes in water quality and quantity can affect aquatic species and habitats and interaction with other potential users of surface water resources. Clearing, grubbing, and topsoil stripping activities can increase the potential for sediment erosion and deposition downgradient, particularly during periods of heavy rainfall or snow melt. These activities will also result in a reduction of evapotranspiration and a corresponding increase in surface runoff, which in turn increases potential for sediment erosion and deposition. To the extent possible, surface flow will be directed around the Project and/or away from disturbed areas. Quarry drainage, and surface runoff collection and controls, will be in place for the quarry at the commencement of operation. Sedimentation ponds will be designed to hold a sufficient volume of water to allow for settling of suspended sediment. These ponds are expected to mitigate potential erosion and sedimentation effects resulting from clearing, grubbing, and topsoil stripping activities. Additionally, as the quarry develops, exposed soil and stockpiles capable of producing sediment laden-runoff will be stabilized with mulch or hydroseed, as appropriate and practical. Surface runoff and quarry drainage will be collected on the quarry floor and will initially drain to the current sedimentation pond, currently in use in the less 3.99 ha quarry within the Project footprint. When required, additional sedimentation ponds will be constructed. Phase 1 and Phase 4 will be designed to provide sufficient area for water management infrastructure to be constructed. The current sedimentation pond will collect all runoff associated with active quarrying limits until the additional pond is constructed. Sedimentation ponds are / will be designed for the water to have sufficient settling occur for the Total Suspended Solids (TSS) concentration to comply with the NSE Pit and Quarry Guidelines for effluent discharge criteria (NSEL 1999). The water will be discharged by gravity and will flow through a ditch where it will re-enter the natural environment. A monitoring plan will be put in place to monitor for changes to the adjacent surface water features that may occur as a result of the Project. Stream 3

Stream 3 is within the groundwater radius of influence for quarry dewatering, however the drainage area will not change as it will not be extracted as part of the quarry. Since the stream is within the groundwater radius of influence there may be a loss in groundwater baseflow due to the lowering of the water table. However, the runoff within the drainage area (189 ha) and the baseflow from approximately 82% (155 ha) of the drainage area (which is outside of the groundwater radius of influence) will be maintained. Therefore, the potential loss in baseflow is expected to be minimal as only 18% of the drainage area is within the groundwater radius of influence.


14

Stream 4

Since the Stream 4 catchment is within the groundwater radius of influence for quarry dewatering, the majority of the infiltration will flow into the quarry rather than discharging into Stream 4 as baseflow. As a result, it is anticipated that the flows in Stream 4 will decrease in the post-development condition as it is expected that only runoff will contribute to the flow in Stream 4 within the property boundary. In addition, the catchment contributing to Stream 4 will be decreased by approximately 27% with the quarry expansion thus decreasing the runoff contributing to Stream 4. Through comparison between the surplus (runoff + infiltration (i.e. baseflow)) contributing to Stream 4 under existing conditions and only runoff contributing under post-development conditions, the flow contribution to Stream 4 will decrease on average by approximately 58% (refer to Tables D-2 and D-3). However, under average annual conditions the average annual water balance analysis predicts minimal runoff will continue to contribute to Stream 4 during the dry months of the year (i.e. summer) on an average annual basis potentially maintaining a perennial stream. Flow and temperature monitoring in Stream 4 will continue to pro-actively assess if/when potential effects may occur. If, through the monitoring, it is determined that the water levels in Stream 4 become too low to provide the current amount or quality of fish habitat, or if water temperature exceeds levels appropriate for the species in Stream 4, authorizations from NSE and/or DFO will be obtained and all conditions of any permits will be implemented. At the southwest property boundary, the runoff contributing to Stream 4 is estimated to increase by approximately 48% compared to pre-development conditions due to the addition of the quarry discharge. However, the estimated increase of flows in Stream 4 at the property boundary are minimal compared to the observed flows in Holland Brook, therefore no measureable impacts to Holland Brook are anticipated. In addition, as stated above, the flows from the quarry will be controlled in sedimentation ponds and slowly released over time thereby decreasing the peak flows from the Property. Stream 6

In the post-development condition, the flow in Stream 6 within the property boundary will be minimal due to the reduction in catchment area and loss of baseflow. Since the Stream 6 catchment is within the area of influence for the quarry, the infiltration component will flow into the quarry rather than discharging into Stream 6 as baseflow. Through comparison between the surplus (runoff + infiltration (i.e. baseflow)) contributing to Stream 6 under existing conditions and only runoff contributing under post-development conditions the flow contribution to Stream 6 will decrease on average by approximately 63% (refer to Tables D-5 and D-6) at the southeast Property Boundary. However, under post-development conditions the runoff contributing to Stream 6 from the upstream catchment area may infiltrate through the rock pillar and contribute to the quarry if rock fractures are present. As a result, authorizations from NSE and/or DFO will be obtained. Due to the reduction in total catchment area (approximately 30%) as well as the change in land use, the surplus contributing to Stream 6 at the property boundary is expected to decrease by 7% compared to pre-development conditions. However, the runoff contributing to Stream 6 at the property boundary is expected to increase by 14% compared to pre-development conditions due to the change in land use from forested/shrubs to quarry floor. As a result, it is anticipated that the flows in Stream 6 will increase at the property boundary. However, the estimated increase of flows in Stream 6 at the property boundary are minimal compared to the measured flows in Holland Brook. Therefore, no measurable impacts to the flow in Holland Brook are anticipated due to the change in catchment area or land use. In addition, the flows from the quarry will be controlled in sedimentation ponds and slowly released over time decreasing the peak flows from the Property Boundary.


15

Wetland 7

Since the catchment area contributing to Wetland 7 will remain unchanged in the post-development condition no surface water impacts to Wetland 7 are anticipated. However, the catchment is within the radius of influence therefore the infiltration component within the catchment area may contribute to the quarry as groundwater inflow. Monitoring will occur in Wetland 7 to assess any changes that may result from the quarry expansion. 3.0 PROPOSED MONITORING

In accordance with the Pit and Quarry Guidelines and the Industrial Approval for the Project, Scotian will develop any required monitoring program to be approved by NSE prior to the start of Project activities. The program will be designed to monitor for changes to surface water features such as streams and wetlands. 4.0 REFERENCES

-- Not applicable

nd = non detect value. Detection limits were not reported

a - Aluminum guideline for FWAL = 5 µg/L for pH <6.5 and 100 µg/L for pH ≥6.5.

b - Cadmium guideline for FWAL is 0.04 ug/L at hardness <17 mg/L, otherwise calculated as 10^(0.83[log(hardness)]-2.46)

d - Lead guideline = When water hardness is 0 to <60 mg/L, the guideline is 1ug/L; when hardness is >60 to < 180 mg/L equation: e 1.273[In(hardness)] -4.705 ug/L is used to determine the lead guideline. At hardness >180 mg/L the guideline is 7 ug/L.

e - Nickel guideline = When water hardness is 0 to <60 mg/L, the guideline is 25 ug/L; when hardness is > 60 to < 180 mg/L equation: e 0.76[In(hardness)] + 1.06 ug/L is used to determine the nickel guideline. At hardness >180 mg/L the guideline is 150 ug/L.

(1) Recovery or RPD for this parameter is outside control limits. The overall quality control for this analysis meets acceptability criteria.

NC (Duplicate RPD): The duplicate RPD was not calculated. The concentration in the sample and/or duplicate was too low to permit a reliable RPDcalculation (one or both samples < 5x RDL).

NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and thespiked amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than 2x that of the native sampleconcentration).

Surrogate: A pure or isotopically labeled compound whose behavior mirrors the analytes of interest. Used to evaluate extraction efficiency.

Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination.

Spiked Blank: A blank matrix sample to which a known amount of the analyte, usually from a second source, has been added. Used to evaluate methodaccuracy.

QC Standard: A sample of known concentration prepared by an external agency under stringent conditions. Used as an independent check of methodaccuracy.

Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference.

Duplicate: Paired analysis of a separate portion of the same sample. Used to evaluate the variance in the measurement.

(1) Recovery or RPD for this parameter is outside control limits. The overall quality control for this analysis meets acceptability criteria.


NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and thespiked amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than 2x that of the native sampleconcentration).

Surrogate: A pure or isotopically labeled compound whose behavior mirrors the analytes of interest. Used to evaluate extraction efficiency.



QC Standard: A sample of known concentration prepared by an external agency under stringent conditions. Used as an independent check of methodaccuracy.
