3 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 3 1 Introduction McIntosh Perry Consulting Engineers Ltd. (McIntosh Perry) is applying for a Category 2 Class A licence to extract below the established groundwater table and a Category 3, Class A licence to extract above the water table for the proposed Goulbourn Pit and Quarry located at Part of Lot 11, Concession 10, Geographic Township of Goulbourn, City of Ottawa. The proposed extraction area consists of approximately 56 HA. Aercoustics Engineering Limited (Aercoustics) has been retained to prepare a Noise Impact Study. The purpose of this study is to provide noise control recommendations in order that the operation within the aggregate pit and quarry will satisfy the Ontario Ministry of the Environment and Climate Change (MOECC) noise guidelines. Sound level limits for the aggregate quarry and pit noise on the residential receptors were first established. These were based on the noise guidelines of the MOECC. Next, the noise predictions of the aggregate pit and quarry operations were performed at these residential receptors. Where the predicted levels were found to exceed the MOECC sound level limits, noise control measures were recommended to satisfy these limits. Figure 1 provides a key plan showing the location of the aggregate pit and quarry. A site plan is provided as Figure 2, illustrating the aggregate pit and quarry area and the locations of local residences (receptors). 2 Site Description Figure 1 provides a key plan showing the location of the proposed pit and quarry and the surrounding area. The site is located north of the intersection of Fernbank Road and Munster Road. The site is in a rural area where aggregate extraction, agriculture and residential subdivisions are the dominant land uses. The proposed aggregate pit and quarry addressed by this noise impact study consists of operations within the lands outlined in Figure 2. These operations include excavation, rock drilling, aggregate haulage/shipping, and processing with a portable processing plant (crushing, screening and washing). An annual tonnage limit of 1,000,000 tonnes is proposed. There are several existing single family residential dwellings in the vicinity of the proposed quarry area. These are identified on Figure 2 as Receptors R01 to R16. Vacant Lots VL17 and VL18 have been used to identify potential noise receptors on noise sensitive zoned lots adjacent to the proposed site. The location of these receptors have been assigned on the basis of guidance provided in NPC-300 and the applicable municipal zoning by-law. Receptor locations R01 to R16 and VL17 to VL18 are shown in Figure 2.

4 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 4 3 Noise Criteria Acoustical Classification The appropriate noise criteria for the receptors in the vicinity of the proposed Goulbourn Pit and Quarry were based on the MOECC Noise Pollution Control publication NPC-300 Environmental Noise Guideline Stationary and Transportation Sources Approval and Planning (August 2013). Points of reception R01 to R16 and VL17 are located in an acoustical environment consistent with the Class 2 (Urban) designation as defined by the MOECC Publication NPC-300. In a Class 2 area, the background sound levels during the daytime (07:00 to 19:00) are defined by man-made sources while in the evening and nighttime periods, natural sounds are typically dominant. In this case, the man-made noise sources include road traffic noise on Fernbank Road and typical residential subdivision noises. Point of reception VL18, which is a potential receptor on a vacant lot, is located in an ambient acoustical environment consistent with the Class 3 (Rural) designation as defined by the MOECC Publication NPC-300. This is reserved for a rural area with a prevailing acoustical environment that is dominated by natural sounds with little or no road traffic. MOECC Sound Level Limits The applicable limits for noise from a stationary source at a noise sensitive point of reception (receptor) in a Class 2 (Urban) area and a Class 3 (Rural) area are outlined in Table 1. Table 1 : Sound Level Limits for Stationary Sources Hourly LEQ (dba) Time of Day Class 2 Area (Urban) Class 3 Area (Rural) Daytime (07:00 to 19:00) 50* 45* Evening and Nighttime (19:00 to 07:00) 45* 40* *or background sound level if higher The noise from a stationary source should not exceed these limits in any hour. At some points of reception in the vicinity of the proposed pit and quarry, the lowest background sound level may be higher than the exclusion limits listed above due to existing activities and road traffic. For conservatism, the exclusion limits were used. 4 Aggregate Pit and Quarry Operation The site plans outline the phases of extraction along with the sequence and direction of operations in each phase. In general terms, the types of work consist of site preparation and rehabilitation, extraction and processing, and shipment off-site.

5 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 5 Hours of Operation The proposed hours of operation are from 7:00 a.m. to 7:00 p.m. Monday to Saturday excluding statutory holidays. At no time shall crushing, rock breaking or blasting take place on a Sunday or a statutory Holiday. No shipping or loading is permitted outside the normal hours of operation. Equipment maintenance may take place outside of the normal operating hours. The proposed hours of operation are summarized below in Table 2. Table 2 : Operating Hours Time of Day Day of Week Operations 07:00 to 19:00 Monday to Saturday Full Operation Extraction, Processing, Rock Drilling, Loading & Shipping Site Preparation and Rehabilitation Site preparation includes the construction of acoustic barriers and any required visual screens specified on the site plan. Topsoil and overburden will be removed. This work will be done primarily with bulldozers, scrapers, trucks, loaders and excavators. Rehabilitation phases will involve similar equipment in establishing the final grading for the site. The site preparation and rehabilitation work described above is not part of the daily operation of the quarry and is of short duration. These construction activities are not considered in the noise control analysis. The equipment used for these activities must satisfy the noise emission requirements of the MOECC document NPC-115 Construction Equipment. By defining a maximum permissible noise emission for construction equipment rather than directly limiting the noise impact at a sensitive point of reception, the MOECC is recognizing that construction is a temporary and largely unavoidable source of noise. In order to minimize the noise impact associated with the construction activities, it is suggested that: Operations should be restricted to the daytime hours. When possible, site preparation should be conducted during the fall, winter, or spring months when there is a reduced level of extraction and when residential windows are more likely to remain closed. Perimeter berms or fences should be constructed as soon as practical during site preparation so as to provide the surrounding residences with some acoustical shielding for the remaining overburden stripping and extraction operations. Extraction and Processing & Transport The maximum annual tonnage to be removed is 1,000,000 tonnes. The proposed pit and quarry will operate with a portable processing plant which follows the working face.

6 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 6 Aggregate will be extracted using two (2) front end loaders at the working face. Material will be transported directly into the primary processing plant. Processed material will be stored in stockpiles in the vicinity of the processing area. Two shipping loaders will be used in the processing area to load highway trucks with finished aggregate product for transport to market. Equipment The extraction, processing and shipment equipment operating in the quarry is limited to: 1 Rock Drill 2 Extraction Loaders or 4 Quiet Extraction Loaders 2 Shipment Loaders 1 Processing Plant 40 Highway truck trips/hr (80 passes/hr) assumed worst case 1 hr volume 5 Noise Predictions & Controls Noise Prediction Methodology The aggregate pit and quarry operations described in the previous section were modelled. Noise predictions were conducted based on the predictable worst case noise impact for each of the aggregate pit and quarry operation areas at each of the receptors. This represents a design case where the site is running at full capacity with all of the equipment operating simultaneously and at locations where noise impact is highest for each receptor. The majority of the time, work would be occurring in other areas of the site with lower associated noise impacts. The noise prediction model was generated using Datakustik s Noise Prediction Software, CadnaA (Version 4.5). This model is based on established noise prediction methods outlined in the ISO standard entitled Acoustics Attenuation of sound during propagation outdoors Part 2: General method and calculation. Noise levels were predicted using existing and proposed topography under conditions of downwind propagation, generally with hard ground modelled in the pit and quarry area and soft ground conditions near the points of reception. Existing foliage surrounding the site was modelled. The pit floor topography was generated using the top of bedrock elevation from measured test pits. Appendix A contains sample stationary source calculations.

7 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 7 The noise impact of the operation was predicted. Where the MOECC sound level limits were calculated to be exceeded, noise control measures were modelled and the noise impact recalculated. This process was repeated until the sound level limits were satisfied. Aggregate Pit and Quarry Noise Sources The reference sound pressure levels used for the aggregate equipment are outlined in Table 3. These were based on similar equipment from the Aercoustics database. Table 3: Reference Sound Pressure Levels of Aggregate Pit and Quarry Equipment Equipment Reference Sound Pressure Level at 30m (dba) Portable Processing Plant (crushing, screening & washing) 87 Rock Drill 79 Extraction Loader 74 Quiet Extraction Loader 70 Shipment Loader 67 1 Highway Truck 25 km/hr The shipment loaders were assumed to operate at a 50 % duty cycle. Recommended Noise Controls The recommended noise controls presented in this section have been determined through noise impact predictions to be effective in controlling the noise generated by the aggregate pit and quarry activity, satisfying the MOECC sound level limits. It should be noted that there may be other effective noise controls that could replace or revise some of the recommended controls of this report. Prior to implementing any changes to the noise controls, appropriate studies should be undertaken to demonstrate that the MOECC sound level limits will be satisfied. Items 12 to 16 in the noise control list below represent the noise controls required only if a dwelling is constructed on the vacant noise sensitive zoned lots to the northeast and the southwest of the proposed quarry property (Receptors VL17 and VL18). These additional noise controls should not be required to be implemented until a dwelling is constructed. If a dwelling is constructed on a noise sensitive zoned lot, the noise control requirements should be reviewed and revised as required by a qualified acoustical consultant to confirm the assumed location, assumed equipment noise levels, and type of construction of the new dwelling. As shown on the draft site plans, there is a proposed Farm Site within the extraction boundary modelled in this study. This would not affect the recommended noise controls.

8 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 8 An acoustic barrier is required to be solid, with no gaps or openings, and shall satisfy a minimum area density of 20 kg/m 2. A staggered earth berm at the site access point is recommended to ensure an uninterrupted height for the entire length. Refer to Figures 3 to 7 for requirements at Phases 1 to 3 during various critical lift heights and an illustration of the timing and implementation of noise controls such as acoustic barriers and extraction direction. The following list presents a comprehensive summary of the recommended noise controls: General: 1. The hours of operation shall be as described in Table A.

No processing shall occur in the Phase 3 area, defined by the area within 280 m of the south extraction limit. Also, operations in this area are limited to the use of a single extraction loader or two quiet extraction loaders. 11. During extraction operations in Phase 3, an acoustic barrier with a minimum height of 8 m shall be located between the processing plant equipment and receptors R06 to R16 and be within 40 m of the plant equipment. It could take the form of un-extracted native material, a working face, a stockpile, an acoustic fence, shipping containers, a combination of these, or any other construction satisfying the requirements of an acoustic barrier. If a dwelling is constructed on the noise sensitive zoned lot immediately west of the site: 12. Prior to extraction, a berm shall be installed along the west property line of the Phase 2 and Phase 3 areas to a height of 9 m and shall remain for the project lifetime. If a dwelling is constructed on the noise sensitive zoned lot immediately east of the site: 13. Prior to extraction, a berm shall be installed along the east property line of the Phase 1 and Phase 2 areas to a height of 6 m and shall remain for the project lifetime. 14. Extraction operations in the Phase 1 area shall proceed in an easterly direction with extraction loaders within 30 m of the working face. The working face shall have a minimum height of 5 m. 15. During extraction operations in the Phase 1 and Phase 2 areas, no processing shall occur within 300 m of the east extraction limit. 16. During all lifts, an acoustic barrier with a minimum height of 12 m shall be located between the processing plant equipment and receptor VL18 and be within 30 m of the plant equipment. It could take the form of a working face, a stockpile, shipping containers, a combination of these, or any other construction satisfying the requirements of an acoustic barrier. Predicted Sound Levels with Controls The predicted worst case noise levels produced by operations within the proposed Goulbourn Pit and Quarry area are summarized in Table 4 below.

However, the MOECC requires consideration of noise impact in choosing the preferred off-property haul route. The proposed haul route for this site is to exit at the southwest corner of the property and turn west onto Fernbank Road towards Dwyer Hill Road and then north towards the highway. Existing truck traffic from nearby aggregate or construction sites was observed. It is understood that this is the only feasible option for off-property haul route, therefore it is the preferred haul route in terms of noise. 7 Conclusions Aercoustics has conducted a noise impact study for the proposed Goulbourn Pit and Quarry. The purpose of this noise impact study was to provide noise control recommendations in order that the operation within the pit and quarry will satisfy the Ontario Ministry of the Environment and Climate Change (MOECC) noise guidelines.

12 McIntosh Perry Consulting Engineers Ltd. Goulbourn Pit and Quarry Page 12 Figure 2 provides a site plan outlining the aggregate pit and quarry areas and the locations of local residences (receptors). To this end, sound level limits, based on the MOECC noise guidelines, were developed. Calculations were then carried out to determine the worst case noise for each of the aggregate pit and quarry operation areas at each of the receptors. Where noise was predicted to exceed the MOECC sound level limits, noise control recommendations and required equivalent source reference sound levels were provided. Refer to Appendix B for a summary of the qualifications of the authors. With the implementation of the recommended noise controls, the proposed aggregate pit and quarry operation is predicted to satisfy the MOECC noise guidelines.
