Triple M Metal LP Mark De Souza 1 Kenview Boulevard, Suite 301 Brampton, ON L6T 5E6 Email: mdesouza@gilimited.ca Re: Noise Impact Study, Proposed Mobile Drainage Station 961 Zelco Drive, Burlington, Ontario HGC Project No.01900751 Dear Mr. De Souza,

Howe Gastmeier Chapnik Limited (HGC Engineering) was retained by Triple M Metal LP to investigate the potential environmental noise impact associated with a proposed end-of-life vehicles drainage station to be located at an existing yard at 961 Zelco Drive in Burlington (Site). The study follows Ministry of the Environment, Conservation and Parks (MECP) guidelines with regards to the impact of noise from the drainage station only.

The stationary noise assessment of the mobile drainage unit is conducted based on a review of the proposed site plan, product specification for ELV Select/Seda ES2 Mobile Drainage Station, sound data from the manufacturer for individual components, aerial photos and a site visit. Commercial offices are not considered noise sensitive with respect to stationary noise impact assessment under MECP guidelines but has been included in this study per City of Burlington requirements.

The analysis includes an assessment of the noise impact anticipated from the drainage station at the closest existing offices, in accordance with MECP guidelines. A computer model of the area was created, using acoustic modelling software, in order to predict the sound levels. The results indicate that the sound emissions of the drainage station meet the applicable noise guideline limits of the MECP at nearby offices. Additional noise mitigation measures are not required. The results are summarized in this report.

Site & Noise Source Description

Figure 1 represents an aerial photograph showing the site and surrounding land uses. The proposed mobile drainage unit will be located within an existing yard (Triple M Metal) as shown on the concept plan attached as Figure 2. The facility operates during daytime hours only from 8:00 am to 4:30 pm Monday to Friday and 8:00 am to 12:00 pm on Saturday. There is an approximate 2 to 3 m high berm along the western and southern boundaries of the site.

Noise Impact Study, Proposed Drainage Station Page 2 961 Zelco Drive, Burlington, ON January 22, 2020

Specifications for the mobile drainage station is attached. The primary sources of sound associated with the drainage station consist of an air compressor and the generator. Sound levels were obtained from the manufacturer for each component. Reasonable operational considerations are described further below.

Criteria for Stationary Sources of Sound

MECP Guideline NPC-300, “Environmental Noise Guideline Stationary and Transportation Sources – Approval and Planning” is the MECP guideline for use in investigating Land Use Compatibility issues with regard to noise. An industrial or commercial facility is classified in MECP guidelines as a stationary source of sound (as compared to sources such as traffic or construction, for example) for noise assessment purposes. In terms of background sound, the development is located in an urban (Class I) acoustical environment which is characterized by an acoustical environment dominated by road traffic and human activity.

In accordance with MECP guideline for stationary noise source assessment, there are no noise sensitive receptors near the site as the surrounding uses consist of warehouses, offices and retail stores. The City of Burlington has requested that the impact of noise from the proposed drainage station be assessed at existing office uses. A site visit was conducted to observe the surrounding land uses and to confirm the locations of windows to offices. It was observed that most of the buildings do not contain any windows facing the Site. For buildings with glazing facing the Site, the windows were observed to be fixed and sealed glazing units. Receptor locations were chosen at the locations of windows corresponding to offices as observed during the site visit, as shown on Figure 3 and listed below.

• R1 – 4420 South Service Road, Tankmart International, 1-storey Building, • R2 – 4400 South Service Road, ZOOK Canada Inc., 1-storey building • R3 – 4380 South Service Road, 2-storey building • R4 – 960 Zelco Drive, Earth Boring, 1-storey building • R5 – 961 Zelco Drive, Triple M Metal Office, 1-storey building

The daytime sound level limit for noise sensitive receptors was used for the purpose of this assessment. NPC-300 stipulates that the exclusionary sound level limit for a stationary noise source in an urban Class 1 area is taken to be 50 dBA during daytime hours (07:00 to 19:00). As a conservative assessment, the exclusionary minimum limit is used as the criterion for all receptors.

The MECP guidelines stipulate that the sound level impact during a “predicable worst-case hour” be considered. This is defined to be an hour when a typically busy “planned and predictable mode of operation” occurs at the subject facility, coincident with a period of minimal background sound. Compliance with MECP criteria generally results in acceptable levels of sound at receptors although there may still be residual audibility during periods of low background sound.

Noise Impact Study, Proposed Drainage Station Page 3 961 Zelco Drive, Burlington, ON January 22, 2020

Assessment of Stationary Sources of Sound

Predictive noise modelling was used to assess the potential sound impact of the drainage at the closest receptors. The noise prediction model was based on sound emission levels for the mechanical equipment, assumed operational profile (during the daytime hours only), and established engineering methods for the prediction of outdoor sound propagation. These methods include the effects of distance, air absorption, and acoustical screening by barrier obstacles.

Because MECP guidelines stipulate that an assessment consider the potential noise impact during a “predictable worst-case hour” of operation. The source levels associated with the equipment and activities are listed in Table I below in terms of sound power level.

Table I: Source Sound Power Levels [dB re 10-12 W]

Source Octave Band Centre Frequency [Hz]

63 125 250 500 1k 2k 4k 8k A Compressor 81 83 87 91 84 80 73 68 89 Generator 75 88 83 92 81 80 73 65 90

The above outlined sound levels and site features were used as input to a predictive computer model. The software used for this purpose (Cadna-A version 2020 build 177.5010) is a computer implementation of ISO Standard 9613-2.2 “Acoustics - Attenuation of Sound During Propagation Outdoors.” The ISO method accounts for reduction in sound level with distance due to geometrical spreading, air absorption, ground attenuation and acoustical shielding by intervening structures such as barriers.

In this impact assessment, we have considered a typical worst-case (busiest hour) scenario to consist of both compressor and generator operating simultaneously for 50 minutes out of an hour with a source height of 1 m. The calculations consider the acoustical effects of distance and shielding by buildings. The unmitigated sound levels due to the mechanical equipment of the drainage station at the closest existing receptors are summarized in the following table. Receptor locations are shown on Figure 3.

The results of the calculations indicate that the predicted sound levels due to operation of the drainage station will be less than the MECP limits at the neighbouring receptors (offices) during a worst-case operational scenario. The predicted daytime sound level contours are also shown in

Figure 3. We note that the Ron Joyce Centre and DeGroote School of Business is located approximately 350 m to the southwest of the site. Based on the results of the nearby receptors shown in Table II, noise impact due to the drainage station is not expected at the school.

Conclusions

Assuming typical worst-case mechanical equipment and operating scenarios associated with the drainage station as described above, the stationary noise analysis indicates that the potential noise impact from the station will meet the applicable MECP criteria at the nearest existing offices without additional noise mitigation measures. The reader is referred to previous sections of this report where the recommendations are discussed in detail.

Thank you for the opportunity to provide this information. Please call if you have any questions.

Yours truly, Howe Gastmeier Chapnik Limited
