EXECUTIVE SUMMARY

HGC Engineering was retained by St. Marys Cement Inc. (Canada) to prepare an updated Acoustic

Assessment Report (“AAR”) for their cement plant in Bowmanville, Ontario. Previously, HGC

Engineering prepared the original AAR for the facility dated August 12, 2010 [1] and an update in

2012 [2]. The current study is required to support an application to the Ontario Ministry of the

Environment (“MOE”) to amend the current approval (No. 3779-9BMQW4) to an Environmental

Compliance Approval with Limited Operational Flexibility and to permit the proposed addition of a

low carbon alternative fuel processing and feed system.

Source sound level measurements of existing equipment were conducted at the facility on July 14, 15

and 22, 2010. Offsite sound level measurements were conducted during the early morning hours of

July 27, 2010. Since the low carbon alternative fuel processing and feed system was not yet

constructed or operational at the time of this study, its source sound emission levels were assumed,

based on measurements of similar equipment conducted by HGC Engineering for past projects. The

source sound levels were used as input to a predictive acoustical model to quantify the environmental

sound emissions of the facility. Acoustic assessment criteria were established in accordance with the

sound level limits in MOE guideline NPC-300.

The acoustical measurements and analysis indicate that the sound emissions of the St. Marys facility

are currently within the sound level limits as set out in MOE guideline NPC-300 and will remain so,

with the addition of the low carbon alternative fuel processing and feed system.

Acoustic Assessment Report Page 1 St. Marys Cement, Bowmanville, Ontario May 13, 2014 1 INTRODUCTION

1.1 Context

The St. Marys Cement Inc. (St. Marys) site is located at 400 Waverly Road South in Bowmanville,

Ontario. A scaled location map of the surrounding area is included as Figure 1. The purpose of the

assessment is to evaluate the overall sound emissions of the facility during a predictable worst case

hour, which is defined as an hour when typically busy operation of the stationary sources under

consideration could coincide with an hour of low background sound.

This report has been prepared in accordance with the MOE guideline documents NPC-233

“Information to be Submitted for Approval of Stationary Sources of Sound” [3], and Appendix A of

“Basic Comprehensive Certificates of Approval (Air): User Guide” [4]. The three Acoustic

Assessment summary tables are presented in Appendix A, in the standardized format required by the

MOE.

Zoning maps identifying the land uses surrounding the facility, obtained from the Municipality of

Clarington and the Township of Darlington, are included as Appendix B. The lands surrounding the

facility are zoned for industrial use to the north, agricultural use to the west and residential use to the

southeast. The nearest points of reception to the site are homes on lands zoned for residential use

approximately 1500 metres to the southeast of the cement plant. There is also a single-storey non-

conforming home on lands zoned for Light Industrial use approximately 350 metres north of the

cement plant. Three key points of reception have been considered in this assessment in order to

represent the nearest receptors, and are labelled as locations R1 through R3 in Figure 2.

During site visits by HGC Engineering on July 14, 15, 22 and 27, 2010, the acoustic environment in

the vicinity of locations R1 and R2 was dominated by road traffic on Highway 401 during both

daytime and nighttime hours. This area is best characterized as a “Class 2” semi-urban area, under

MOE noise assessment guidelines. The St. Marys facility was observed to be faintly audible during

both daytime and nighttime hours during periods of low background sound.

In the vicinity of location R3, the local background sound was dominated by a preponderance of road

traffic on Highway 401 during both daytime and nighttime hours, as well as by frequent rail traffic

Acoustic Assessment Report Page 2 St. Marys Cement, Bowmanville, Ontario May 13, 2014 on the CN principal mainline railway that passes between R3 and the facility. This locale is best

characterized as a “Class 1” urban area. The St. Marys facility was observed to be completely

inaudible at location R3 during daytime hours, and audible at times during lulls in road traffic noise

during nighttime hours.

1.2 Summary of Updates Addressed in This Assessment Report

This assessment includes the following updates:

1. Since the previous assessment, the material/conventional fuel storage and handling operations at

the dock area (operated by Cargo Dockers) have been granted a separate approval by the MOE

(ECA No. 6346-9DSL5P), and are thus not explicitly considered herein.

2. Source identifiers have been modified, where feasible, to match those of the Emission Summary

and Dispersion Modeling (“ESDM”) report prepared by BCX Environmental Consulting.

3. Sound emissions associated with the proposed addition of a low carbon alternative fuel

processing and feed system have been included herein.

4. The SMC facility is assessed in accordance with MOE guideline NPC-300 [5], which superseded

the guideline employed in the previous assessments, NPC-205.

2 FACILITY DESCRIPTION

The site operates 24 hours per day, 7 days per week. The plant primarily produces Portland cement

by combining materials bearing calcium carbonate, silica, alumina and iron oxide at high

temperatures to produce cement clinker. The clinker is subsequently ground with finishing materials

such as gypsum and limestone to produce cement. Other operations at the facility are ancillary

operations such as comfort heating and emergency generators.

2.1 Cement Manufacturing Operations

2.1.1 Raw Material and Fuel Delivery and Storage

The main raw material (limestone) is supplied by the on-site limestone quarry. Limestone is

transferred from the primary surge pile via an enclosed conveyor system to a secondary

Acoustic Assessment Report Page 3 St. Marys Cement, Bowmanville, Ontario May 13, 2014 crusher/screen system which is controlled by baghouses. Processed limestone is then fed via

enclosed conveyors to limestone storage silos.

Other raw materials (e.g. sand, iron, overburden and ash) are delivered by truck; additives (gypsum)

and solid fuels (i.e. petroleum cokes) are delivered by ship. Gypsum and conventional solid fuel (i.e.

petroleum coke and coal) are transported by truck to the plant from the dock. A small portion of the

conventional solid fuels is delivered by truck via the main plant road. SMC’s material/conventional

fuel storage and handling operations at the dock area are approved under ECA # 6346-9DSL5P dated

December 5, 2013.

Most raw materials are stored at the plant in storage silos or storage buildings. Conventional solid

fuels from the dock are deposited into the fuel underground hopper from where they are transferred

into the fuel storage silos.

Sorted and pre-processed (size reduced) clean wood and/or low carbon alternative fuel will be

delivered by enclosed trucks and off-loaded into a storage and handling area inside a fully enclosed

fuel building.

2.1.2 Clinker Production

Limestone, sand, iron oxide, and overburden sources are proportionately fed from the raw material

storage silos and storage building via an enclosed conveyor belt system to a raw mill. Emissions

from the raw mill are controlled by the kiln feed baghouse, venting through the main kiln stack. In

the raw mill, the raw materials are ground and mixed to a uniform particle size and dried. The raw

mill uses the hot exhaust gases from the pre-heater tower to dry the raw meal. The dried raw meal is

stored in the kiln feed silo.

Conventional solid fuels are fed to the fuel milling system from the storage silos. Emissions are

controlled by the fuel mill baghouse venting through the main kiln stack. Milled conventional fuel

(fuel meal) is fed to the kiln burner and calciner burner through their individual fuel feed systems

(i.e. two fuel meal silos and dust collectors).

Clean wood and/or low carbon alternative fuels will undergo additional size reduction inside the new

fuel building. The homogenized fuel will then be fed via enclosed screw feeder system directly into

Acoustic Assessment Report Page 4 St. Marys Cement, Bowmanville, Ontario May 13, 2014 the pneumatic solid fuel delivery systems that feed the main kiln burner and/or the calciner

burner. The burning zone temperature in the kiln and calciner are over 2,100°C and 1,375°C,

respectively.

The low carbon alternative fuel feed system will be fully integrated with the plant control system to

regulate and limit the fuel substitution rates into the kiln and/or calciner to maintain the required

temperature profile and system conditions.

All air from the new low carbon alternative fuel building and solid fuel delivery system will be

directed through the kiln burner and/or calciner burner.

Dried raw meal is fed, via air slides and bucket elevators, up to a dual string pre-heater tower

consisting of a series of cyclones. As the raw meal progressively passes through a pre-heater string

and its cyclones, it encounters progressively hotter gases from the kiln. Prior to being directed into

the kiln, the pre-heated material is fed into a pre-calciner where the material temperature is raised to

840°C. In the kiln, the raw meal temperature is raised to over 1,500°C. The chemical reactions and

physical processes transform the raw meal into clinker. Flue gases from the kiln pass through the

pre-heater strings and the bypass stream and raw mill to the kiln baghouse and are exhausted to the

atmosphere via the main kiln stack.

The clinker product is cooled by passing ambient air across the product. This air is directed into the

kiln for use as combustion air. The clinker is then further cooled in a reciprocating grate cooler,

which achieves a lower clinker discharge temperature by passing an additional quantity of air

through the clinker. This additional air passes through the cooler baghouse prior to being exhausted

to the atmosphere through the cooler stack.

Clinker exits the clinker cooler at an average temperature of between 100 and 200°C onto an

enclosed conveyor system, which feeds one of four clinker storage silos. Cooled clinker from the

clinker storage silos is conveyed to the roller press where it is pre-ground. Pre-ground clinker is then

transferred into the cement finish mill feed silos.

Acoustic Assessment Report Page 5 St. Marys Cement, Bowmanville, Ontario May 13, 2014 2.1.3 Cement Production

Cement finishing is accomplished in three individual ball grinding mills. Clinker, limestone and

gypsum are milled together to produce cement. The three finish mills are controlled by individual

baghouses venting through two finish mill stacks.

The finished cement product is transferred into product storage silos. Product can be dispatched via

tanker truck or by ship.

In addition to finished cement product, the plant also ships clinker. Cement and clinker are

transported to the dock using an enclosed conveyor system.

2.1.4 Other Associated Equipment/Operations

 In an effort to reduce nitrogen oxides (NOx) and sulphur dioxide (SO2) emissions, the Facility uses a

Selective Non-Catalytic NOx Reduction (SNCR) ammonia solution injection system and hydrated

limestone injection while reducing NOx emissions and SO2 emissions, respectively.

2.2 Ancillary Operations

At the Facility, ancillary operations include:

Propane and No.2 oil-fired comfort heating units;

Three (3) emergency diesel generators;

Maintenance shop; and

Eight (8) laboratory fume hoods.

Noise sources associated with below-grade quarry operations adjoining this site are covered under an

aggregate license from the Ministry of Natural Resources (Number 318) and therefore have not been

included in this assessment.

The primary sound sources associated with the site considered herein include the cement plant and

CBM Aggregates operations, as well as onsite movements of trucks and front end loaders.

Acoustic Assessment Report Page 6 St. Marys Cement, Bowmanville, Ontario May 13, 2014 3 SOUND SOURCE SUMMARY

A Sound Source Summary is included as Table A1 in Appendix A, which lists the sources associated

with the facility, in the standard format required by the MOE. An Emission Summary and Dispersion

Modeling (“ESDM”) report was prepared by BCX Environmental Consulting as part of an

application for an Amended Environmental Compliance Approval for the facility. Where applicable,

the source identification numbers and descriptions used in this acoustical assessment follow those of

the ESDM. For sound-only sources which are not sources of air emissions, an identification number

has been given in this assessment report of the form NS-## (e.g. NS-01).

Figures 3a through 3c show the locations of each noise source. Except where noted otherwise, sound

levels of the individual sources were measured onsite on July 14, 15 and 22, 2010, primarily using

sound intensity methods. Unlike a simple sound level meter with an omni-directional microphone,

sound intensity instrumentation utilizes a highly directional probe and sophisticated analyzer to

measure both the magnitude and direction of sound. This approach therefore has excellent immunity

to background noise and cross-interference from sources located close together. Details of the

measurement methods used to quantify the sound power of each source are listed in Appendix C.

Sources which were found to be acoustically insignificant are listed in Appendix D. The primary

sources of sound at the site are described below.

3.1 Surge Pile

There are two surge piles (represented as source PPILE) adjacent to the below-grade quarry

operations. After being processed through a below-grade primary crusher in the adjacent quarry,

limestone extracted from the quarry is transferred to an above-grade surge pile area east of the

cement plant, which includes two material stockpiles, as well as two material silos. The dominant

noise source associated with the surge pile area is the sound of rock falling onto either of the two

stockpiles (only one of which can receive material at a given time). When material is delivered to

either of the two storage silos, sound emissions from this area are insignificant. St. Marys personnel

indicate that typically the stockpiles receive aggregate material 80% of the time and the storage silos

receive material 20% of the time, which has been assumed for the purposes of this assessment.

Acoustic Assessment Report Page 7 St. Marys Cement, Bowmanville, Ontario May 13, 2014 3.2 Secondary Crusher

Material is drawn from the surge pile area via a feeder system below the stockpiles/silos for further

processing in the secondary crusher (SCRUSH). The secondary crusher is housed inside a building

which has three doors that can remain open during operation: one facing southwest (SCRUSHa) and

two facing southeast (SCRUSHb and SCRUSHc). The secondary crusher has been assumed to

operate continuously during a typical worst case hour of operation.

3.3 Process/Dust Collector Exhausts

There is a number of process exhausts located on various rooftops throughout the plant. With the

exception of the Finish Mill 2 Stack (FM2) and the Cooler Building Baghouse Exhaust (CBH), noise

emissions from all acoustically significant process/dust collector exhausts were measured during the

site visits. The Finish Mill 2 Stack and the Cooler Building Baghouse Exhaust were not accessible

for direct acoustic measurement; therefore the noise emissions associated with these sources were

calculated based on the physical characteristics of the fans in each of the systems using formulae

from standard engineering reference texts. These sound levels were calibrated using the predictive

acoustical model (see Appendix E) based on numerous sound pressure level measurements

conducted both on and off the site.

3.4 Process Fans/Motors

There are a number of process fans located east and west of the Kiln Feed Baghouse (NS-06 through

NS-08, NS-14 and NS-15). These fans and the associated motors were measured during the site

visits. The kiln induced draft (ID) fans, east of the Kiln Feed Baghouse, were observed to emit a

tonal sound from a space between the concrete motor platforms and the fan casings, which have been

included in this assessment as separate sources. These fans were assumed to operate continuously

during a predictable worst case hour of operation.

3.5 Baghouse Screw Conveyors

Sound emissions from the screw conveyors located beneath the Kiln Feed Baghouse (NS-05), Kiln

Bypass Baghouse (NS-12) and the Cooler Building Baghouse (NS-13) have been included in this

assessment, and assumed to occur continuously during a predictable worst case hour of operation.

Acoustic Assessment Report Page 8 St. Marys Cement, Bowmanville, Ontario May 13, 2014 3.6 Open Doors

A number of open overhead and man doors leading to process areas around the facility were

observed to emit non-negligible sound (SCRUSHa, SCRUSHc, FMBLDa, FMBLDb and

KFMBLDd) and were measured and included herein. The measurements were conducted in the plane

of the openings, and each of these sources was assumed to operate continuously during a predictable

worst case hour of operation.

3.7 Kiln Cooling Fans

There are twelve horizontal fans (NS-01) and four vertical fans (NS-02 and NS-03) used to cool the

walls of the kiln, all of which have been included in this assessment, assumed to operate

continuously during a predictable worst case hour of operation. Several sound intensity

measurements conducted over the surface of the kiln found the walls of the kiln itself to be

acoustically insignificant.

3.8 Cooler/Burner Building Heat Exchanger

This assessment considers sound emissions from a heat exchanger on the east side of the

Cooler/Burner Building, which includes twelve axial fans (represented as CCBLDa and CCBLDb).

The heat exchanger fans were assumed to operate continuously during a predictable worst case hour.

3.9 Trucking Activities

3.9.1 Cement Trucking Activities

Cement powder is shipped from the St. Marys site via tractor trailers, which enter the site via

Waverly Road and travel to an enclosed area beneath the storage silos at the north end of the cement

plant to be loaded. St. Marys personnel indicate that, during a predictable worst case hour of

operation, up to nine trucks could visit the site (VTa). In addition to onsite movement of cement

trucks, this assessment includes two trucks continuously idling in the loading area during a

predictable worst case hour of operation (NS-09 and NS-10). Sound levels of moving and idling

trucks gathered for similar past projects on file at HGC Engineering were used for this assessment.

Acoustic Assessment Report Page 9 St. Marys Cement, Bowmanville, Ontario May 13, 2014 3.9.2 Petcoke/Coal/Gypsum Trucking Activities

Petcoke, coal and gypsum are delivered from the dock area to the cement plant by tractor trailer. St.

Marys personnel indicate that, during a predictable worst case hour of operation, up to five trucks

could carry petcoke/coal/gypsum between the dock area and the cement plant (VTb and VTc,

respectively). Sound levels of moving trucks gathered for similar past projects on file at HGC

Engineering were used for assessment of these sources.

3.10 Emergency Generators & Water Pump

The St. Marys site includes three emergency diesel engines, two of which operate generators and one

which operates a water pump system. Although the emergency operation of a generator/pump system

during a power outage is exempt from acoustic assessment under MOE guidelines, as a life safety

event, the periodic operation for maintenance purposes must be considered. St. Marys personnel

indicate that each of the emergency generators/pump is tested during daytime hours on a weekly

basis for approximately 30 minutes. Although the units are not typically all tested at the same time,

this assessment conservatively considers simultaneous daytime operation of all three emergency

systems. Under MOE guidelines, emergency generators are assessed separately from other

equipment at the facility, as discussed below in Section 6.2.

Each of the diesel engines outlined above is equipped with a combustion exhaust silencer, the

acoustic performances of which are unknown; the measurements and predictive analysis of these

sources include the benefit of the installed exhaust silencers.

3.11 Low Carbon Alternative Fuels

The low carbon alternative fuels processing and feed system will receive fuel materials by truck

(VTd) at an estimated rate of five per hour. The fuel materials will be stored within a fully enclosed

building, and delivered by front end loader (NS-16) to a processing/delivery system consisting of

shredders and a hopper system (collectively represented by NS-17) that will deliver the processed

fuel to the kiln. Manufacturer’s sound data for the fuel processing/delivery system indicates a sound

power level of 108 dBA without fuel material passing through the equipment; no data was available

for the equipment while processing fuel material. Therefore, sound emission data for similar

equipment measured by HGC Engineering for a past project (with a sound power level of 117 dBA)

Acoustic Assessment Report Page 10 St. Marys Cement, Bowmanville, Ontario May 13, 2014 was assumed for the purposes of this assessment. Although the front end loader and

processing/delivery equipment is proposed to be enclosed within a building, this assessment

conservatively excludes the acoustic benefit that would be afforded by any such structure.

3.12 CBM Aggregates

Aggregate material is transferred from the below grade quarry to the CBM Aggregates yard on the

west side of the site by rock trucks (CBMa). St. Marys personnel indicate that, during a predictable

worst case hour of operation, rock trucks could make up to 15 round trips to the storage area.

Aggregate material is shipped offsite from this area by tractor trailers, which enter the site via

Waverly Road and travel directly to the CBM Aggregates yard. St. Marys personnel indicate that,

during a predictable worst case hour of operation, up to 15 tractor trailers could visit the site to ship

aggregate materials (CBMb). This assessment also includes the sound of an idling truck in the

aggregate yard (CBMc) as well as a front end loader (CBMd), both of which were assumed to

operate continuously during a predictable worst case hour. Sound levels of moving and idling trucks

as well as the front end loader were based on data from past projects on file at HGC Engineering.

3.13 Summary of Predictable Worst Case Hour Activities

The following table summarizes the predictable worst case hour of operation at the St. Marys site,

which have been considered for the purposes of this assessment.

Acoustic Assessment Report Page 11 St. Marys Cement, Bowmanville, Ontario May 13, 2014

Table 1: Summary of Predictable Worst Case Hour of Operation

Source Type/Name Predictable Worst Case Hour Activity St. Marys Cement Surge Pile Active (80%) Process Equipment Active Cement Trucks 9 at 40 km/hr Petcoke/Coal/Gypsum Trucks 5 at 40 km/hr Idling Trucks (entrance/exit) 2 for 60 min Low Carbon Alternative Fuel Trucks 5 at 40 km/hr Low Carbon Alternative Fuel Front End Loader Active Low Carbon Alternative Fuel Processing Equipment Active CBM Aggregates Rock Trucks 15 at 40 km/hr Aggregate Trucks 15 at 40 km/hr Idling Truck Active Front End Loader Active

The source sound levels were used to develop the sound source inventory included as Table A1 in

Appendix A, and were input to a predictive computer model (see Appendix E) to quantify the sound

emissions of the facility during the predictable worst case hour described above.

4 POINT OF RECEPTION SUMMARY

The nearest residentially zoned lands are located southeast of the St. Marys cement plant. In addition,

there is a single storey non-conforming residence on lands zoned for Light Industrial use north of the

cement plant. Three key receptors were chosen to represent these areas, which are shown as locations

R1 through R3 in Figures 2 and 4.

Location R1 represents an upper storey window of a two storey home on the south side of Watson

Drive, approximately 60 metres from the site boundary, between 550 metres and 950 metres from the

Cargo Dockers operation and between 1250 metres and 1650 metres from the cement plant. Location

R2 represents a single storey home on the south side of Cedar Crest Beach Road, approximately 90

metres from the site boundary, between 500 and 900 metres from the Cargo Dockers operation and

between 1300 and 1700 metres from the cement plant. Location R3 represents a non-conforming

single storey home approximately 350 metres north of the cement plant. This home is situated

approximately 80 metres south of Highway 401, and approximately 325 metres north of a CN

Acoustic Assessment Report Page 12 St. Marys Cement, Bowmanville, Ontario May 13, 2014 principal mainline railway. In the case of location R1, the most-potentially impacted point on the

property is the upper-storey window, because this position is most exposed to the sources at the

facility and benefits the least from ground absorption and shielding by intervening obstructions.

Because the homes represented by R2 and R3 are single storey, these receptor locations represent

first storey windows. Each point of reception is described briefly in Tables A3.1 and A3.2, the

Acoustic Assessment Summary Tables.

In the vicinity of locations R1 and R2, the local background sound was dominated by road traffic on

Highway 401, during both daytime and nighttime hours, with the St. Marys facility faintly audible

during both daytime and nighttime hours during periods of low background sound. The St. Marys

facility was observed to be completely inaudible at location R3 over the preponderance of road

traffic sound from Highway 401 during daytime hours; during nighttime hours, the facility was

audible at times during lulls in road traffic noise.

5 ASSESSMENT CRITERIA

The appropriate document for defining the applicable sound level limits is MOE guideline

NPC-300 [3]. The details by which the applicable sound level limits were established for the

assessment of this facility are provided in Appendix F. For the purposes of this assessment, the

applicable sound level limits are 45 dBA at locations R1 and R2 and 50 dBA at location R3. These

limits are included in Tables A3.1 of Appendix A.

Some types of sound have a special quality which may tend to increase their audibility and potential

for disturbance or annoyance. For tonal sound, MOE guideline NPC-104 [6] stipulates that a penalty

of 5 dBA is to be added to the measured source level. A tonal sound is defined as one which has a

“pronounced audible tonal quality such as a whine, screech, buzz or hum”. In the subsequent

analysis, a tonal penalty has been applied to sources as indicated in Table A1 of Appendix A.

6 IMPACT ASSESSMENT

6.1 Non-Emergency Equipment

The sound levels of the facility were predicted to be 41 dBA, 39 dBA and 50 dBA at locations R1,

R2 and R3, respectively, during both daytime and nighttime hours. The results of the analysis are

Acoustic Assessment Report Page 13 St. Marys Cement, Bowmanville, Ontario May 13, 2014 summarized in Table A3.1 of Appendix A. Details of the prediction methods are summarized in

Appendix E, and sample calculation results are included as Appendices G and H.

The results of the analysis indicate that sound emissions of the facility meet the sound level limits

specified by the MOE at all points of reception during all hours of the day and night. Despite minor

differences between daytime and nighttime operation at the St. Marys site, the predicted sound

exposure level contours are identical during day and night. Therefore, Figure 4 shows the predicted

sound exposure level contours, LEQ [dBA] during a predictable worst case hour of operation at the St.

Marys site, applicable during either daytime or nighttime operations.

6.2 Emergency Equipment

NPC-300 stipulates that sound emissions from emergency equipment operating in non-emergency

situations, such as maintenance testing, be assessed independently of all other stationary sources of

noise. Further, the sound level limits for emergency equipment are 5 dB greater than the limits

otherwise applicable to stationary sources. Since the emergency equipment at the subject site is

tested during daytime hours only, the sound level limit applicable thereto is 55 dBA (5 dB greater

than the daytime exclusionary minimum criterion of 50 dBA). The offsite sound levels of emergency

equipment at the subject site, which are summarized in Table A3.2 in Appendix A, were predicted to

range from 18 to 28 dBA at locations R1 through R3, which are well within the applicable limit.

7 CONCLUSIONS

The acoustical measurements and analysis indicate that the sound levels of the St. Marys site are and

will be within the applicable sound level limits as set out in MOE publication NPC-300, under

typical “predictable worst case” operating conditions.

ZONING MAPS

The extent and boundaries of the said zones are shown on the Schedules attached

hereto which form part of this By-law. Such zones are described on the Schedules by

the appropriate zone symbol.

4.1 SPECIAL EXCEPTIONS

A number of the zones set out in this By-law and listed above, contain a section which

describes "special exceptions". Special exceptions are indicated on the Schedules to

this By-law by adding a dash (-) and a number to the basic zone symbol (for example,

R1-3).

Where a special exception is applied to a lot, such lot may only be used in accordance

with the special exceptions described in the text. Where there is a conflict between a

special exception and any other section of this By-law, the special exception shall apply.

Where the special exception is silent on any matter, the provisions of this By-law shall

apply.

APPENDIX C Measurement Methods and Instrumentation

Acoustical measurements were conducted using the methods and instrumentation described below.

All instrumentation was within its laboratory calibration period. Field checks of correct calibration

were made before and after the measurements. Weather conditions during the site visits were suitable

for outdoor acoustical measurements.

Source Sound Intensity Measurements

Sound intensity measurement techniques were employed to measure the sound power of each source.

Methods from ISO 9614-2 “Acoustics - Determination of sound power levels of noise sources using

sound intensity - Part 2: Measurement by scanning” [7] were employed in this regard. Sound

intensity measurement instrumentation has a high inherent ability to reject extraneous sounds

originating from outside the measurement control-volume, and can therefore separate the sound

emitted by each component. The measurements were conducted in 1/3 octave bands using a Hewlett

Packard model 3569A Real Time Frequency Analyzer, connected to a G.R.A.S. model 50AI-HP

sound intensity probe, equipped with a phase-matched pair of G.R.A.S. type 40AK condenser

microphones.

Sound Pressure Level Measurements

Sound pressure level measurements were conducted at a number of locations on the subject site, the

results of which were used to validate the results of the acoustic model (see Appendix E). These

measurements were conducted using the analyzer outline above, connected to a Brüel & Kjær type

4188 microphone.

Sound pressure level measurements were conducted in the vicinity of locations R1 through R3 using

the equipment outlined above, as well as a Larson Davis 831 Precision Integrating Sound Level

meter, the results of which were also used to validate the model, and to evaluate the sound emission

of the facility.

APPENDIX D Acoustically Insignificant Sources

The following ESDM sources were found to be acoustically insignificant during the site visits of July

14, 15 and 22, 2010, or are associated with below-grade quarry operations adjoining the site and

have not been included in this assessment:

NTT North Transfer Tower PCRUSH Primary Crusher

QGARAGE Quarry Office Propane Fired Heater QUARRY Quarry Operations SCREEN Screen

SGCRUSHE Slag/gypsum Crusher SGHOPPER Slag/gypsum Hopper

TT Transfer Tower TT2 Cement Transfer Tower TT3 Transfer Tower

APPENDIX E Details of Predictive Acoustical Modelling

The source sound power levels were used as input to a predictive computer model (Cadna-A version

4.5.145). The model is based on the methods from ISO Standard 9613-2.2 “Acoustics - Attenuation

of Sound During Propagation Outdoors” [8], which accounts for reduction in sound level with

distance due to geometrical spreading, air absorption, ground attenuation and acoustical shielding by

intervening structures (or by topography and foliage where applicable). This modeling technique is

acceptable to the MOE.

Digital topographical data for the subject site was provided by St. Marys, and Ontario Base Maps

were obtained for the area surrounding the site; all topographical data was input into the acoustic

model and supplemented based on site observations, where appropriate. Ground attenuation was

assumed to be spectral for all sources, with the ground factor (G) assumed to be 0.4 on roadways and

amongst the plant buildings on the St. Marys site and 1.0 in all others areas, each chosen to achieve

optimal agreement between predictions and the sound levels measured both offsite and at a number

of locations around the facility. The temperature and relative humidity were assumed to be 10° C and

70%, respectively.

The predictive modeling considered one order of reflection, with shielding/reflections afforded by

buildings both on and off the subject site. Spectral absorptive characteristics were applied to each

structure as appropriate, typically with values representative of corrugated metal, concrete block or

steel.

Most mechanical sources were modeled as point sources of sound (shown as crosses in Figures 3a

through 3c and 4). Several building envelopes and open doors were modeled as vertical area sources

(shown as a green line). Several screw conveyors were modelled as line sources (shown as thin lines

in Figure 3a through 3c and 4), as were onsite movements of trucks. Time weighting factors were

applied to the sound from on-site trucks based on a speed of 20 km/h.

The predictive model was found to agree well with the results of numerous measurements conducted

around the cement plant, as well as in the vicinity of locations R1/R2 and R3 (within 1 dB).

APPENDIX F Acoustic Assessment Criteria

MOE Publication NPC-300, “Environmental Noise Guideline, Stationary and Transportation Sources

– Approval and Planning” [5] draws a distinction between sound produced by traffic sources and that

produced by industrial or commercial activities, which are classified as stationary sources of sound.

In essence, the sound from the stationary sources is evaluated against (i.e. compared to) the typical

background sound at any potentially impacted, sound-sensitive points of reception (e.g., residences).

Background sound is considered to include road traffic sound and other typical sounds, but excludes

the sound of the facility under assessment. In general, the acceptability limits for stationary sources

are site dependent, and are based on the existing ambient background sound levels in the area of the

subject site.

Publication NPC-300 stipulates that the sound level limit for a stationary source which operates

continuously, 24 hours per day, in a Class 1 (urban) or Class 2 (semi-urban) environment is the

greater of the minimum one-hour energy-equivalent (LEQ) background sound level, or the

exclusionary minimum limit of 45 dBA. The guideline also stipulates that the noise assessment shall

consider a predictable worst-case hour, which is defined as an hour when typically busy operation of

the stationary sources under consideration could coincide with an hour of low background sound.

The characteristic background sound level can be determined through automated long-term

measurement, or by predictive analysis based on road traffic volume counts, in cases where the

background sound is dominated by road traffic. The MOE guidelines also stipulate that the noise

assessment shall consider a predictable worst-case hour, which is defined as an hour when typically

busy operation of the stationary sources under consideration could coincide with an hour of low

background sound.

The applicable sound level limits were prepared when NPC-205 was the MOE guideline in use for

Class 1 and Class 2 areas. The sound level limits in NPC-300 do not differ from those of NPC-205,

in the context of the subject site, and thus the previously approved limits remain unchanged, and are

45 dBA at locations R1 and R2 and 50 dBA at location R3. Details regarding the derivation of the

applicable limits are included below.

Locations R1 and R2

Observations and measurements conducted in the vicinity of locations R1 and R2 indicate that

background sound levels are likely to fall below the exclusionary minimum levels set out by NPC-

300 during the quietest hours of the night. Accordingly, the exclusionary minimum limit of 45 dBA

is applicable at locations R1 and R2.

Location R3

Background sound level monitoring was conducted by Aercoustics Engineering Limited from

December 4 through December 6, 2009 in the vicinity of location R3, when the St. Marys site was

shut down (included at the end of this Appendix). The minimum measured hourly LEQ sound level

during nighttime hours was 57 dBA. However, the sound level monitoring was conducted at a

location representative of the north façade of location R3, whereas the most potentially impacted

location on this property is the south façade, as this location is most exposed to the site under

assessment, and is shielded from Highway 401 by the home itself. A correction factor of 15 dBA was

therefore applied to the minimum monitored sound levels outlined above to estimate the background

sound due to Highway 401 at the rear façade of the home represented by location R3. This correction

factor is consistent with the correction factor specified in the MOE publication, “Environmental

Noise Assessment in Land Use Planning”. Given the preponderance of road traffic on Highway 401

(a significant portion of which is heavy trucks), and the modest degree of shielding afforded by the

bungalow represented as location R3, a correction factor of 15 dBA to account for shielding afforded

by this building likely underestimates the background sound significantly. Nevertheless, with the

factor applied, the exclusionary minimum limit of 45 dBA would be conservatively applicable at

location R3.

As outlined previously, receptor R3 is situated on lands zoned for Light Industrial use, and is

therefore a non-conforming land use. It is located adjacent to several industrial facilities/operations,

and thus the surrounding environment is not typical of a residential area. The MOE sound level

limits do not strictly apply to a non-conforming property, because by its very nature, a non-

conforming use is inconsistent with the surrounding land uses and with the municipality’s long term

planning objectives for the area. The zoning designation for these lands specifies that residential land

uses are prohibited (Section 23 of the Municipality of Clarington Zoning Bylaw 84-63). On this

basis, the sound level limits for St. Marys were previously established to be 50 dBA during the

nighttime period, at location R3.

APPENDIX G Sample Calculation Results - Condensed, Overall dBA Format

In the following tables of calculation results, the column headings for the various sound attenuation mechanisms follow the terminology of ISO Standard 9613-2. LxD and LxN are the A-weighted, one-hour energy-equivalent source sound power levels, which include the effects of any source-abatement measures included in the model, penalties for distinctive source character, where applicable, as well as any time-averaging effects for intermittent sources. LrD and LrN are the A-weighted, one-hour energy-equivalent sound levels at the points of reception. The results are presented in terms of overall A-weighted results, at the most impacted off-site points of reception.
