Introduction Terrapure Environmental (Terrapure), owner and operator of the Stoney Creek Regional Facility (SCRF; Facility), has initiated an Individual Environmental Assessment (EA) under the Ontario EA 3 Act seeking approval to provide an additional 3,680,000 cubic meters (m ) of disposal capacity to their SCRF through a reconfiguration of the site back to its original Ministry of the Environment and Climate Change-approved footprint. This reconfiguration would allow Terrapure to utilize the existing space more efficiently while retaining the same overall geographic size of the site. Terrapure's SCRF has been an important part of the local community since it was approved by the Ministry of the Environment and Climate Change in 1996. The existing SCRF is only permitted to accept solid, non-hazardous residual materials from commercial, industrial and institutional sources. These are truly "end of life" materials that have exhausted all recycling options. Putrescible waste (i.e., municipal solid waste, organic material) disposal is not permitted at the SCRF. The total approved capacity under the Environmental Protection Act approvals at the existing SCRF is 3 6,320,000 m with an approved maximum annual volume of 750,000 tonnes of solid, non-hazardous industrial residual materials. The proposed changes would not change the type or annual volume of materials currently accepted at the facility, nor the maximum number of vehicles to the site per day. The SCRF is expected to reach capacity in the next 16 to 22 years, accepting a combination of residual material and industrial soils or "fill," which is required to bring the site to final grade. By changing the configuration of the site and accepting more residual materials than industrial soils, it is expected that the SCRF may be able to close sooner than currently anticipated (within 13-20 years) because the market for residuals is much stronger and more consistent than that for soils. The EA Act requires that proponents describe the environment that may potentially be affected or may reasonably be expected to be affected, directly or indirectly, by the alternatives and the undertaking proposed as part of an EA. As such, this report characterizes the Noise existing conditions presently found at the SCRF.

2.

Study Areas From a Noise environment perspective, the characterization of existing conditions within the following study areas, are appropriate to this EA: •

Site Study Area, including all lands within the existing, approved boundaries of the SCRF, as defined by Environmental Compliance Approval (ECA) No. A181008, as amended.

•

Local Study Area, including all lands within a 500 meter (m) radius of the Site Study Area boundaries.

The Study Area for the noise discipline was defined by the area extending 500 m from the existing SCRF property boundary. The MOECC Noise Screening Process Questionnaire requires that industries with significant potential environmental noise profiles or equipment evaluate the off-site environmental noise impact within 1 kilometre (km) from the site; the noise impact beyond 1 km is expected to be environmentally insignificant. Maximum sound level impacts will occur close to the

property line and within a 500 m Local Study Area which is representative of a more detailed and worst-case scenario assessment. The rationale for the Local Study Area for the noise discipline is that the off-site environmental noise impact from the existing Facility or the development of the proposed alternatives to provide additional capacity will be defined by the sound power generated by the equipment and activities on-Site and the proximity and line-of-sight noise exposure to the off-site receiver locations which are the subjects of this analysis. In the absence of other developments and intervening built structures, such as businesses or institutions, the rural residential dwellings within the Local Study Area represent the receiver locations which are the subject of the assessment. The nearest existing residential dwelling is approximately 110 m northeast of the existing property boundary. There are approximately 500 existing residential dwellings within the Study Area with the largest concentrations to the south and southwest of the site along Mud Street. An additional subdivision is being constructed to the north. The Noise study areas are illustrated in Figure 2.1, below.

Methodology Available secondary sources of information were collected and reviewed to characterize Noise existing conditions within the study areas. The following sources of secondary information were collected and reviewed: •

Review of historic complaints

•

Review of current zoning plans, definitions and land use designations

•

MOECC technical guidelines and standards

•

Rotek Environmental Inc. Semi-Annual Noise Report. June 2012

•

AECOM Acoustic Assessment Report – June 2013

•

Background Noise Analysis (BNA) – historic ambient monitoring data used to determine the existing acoustical conditions for the area

The environmentally significant noise sources or activities occurring on-Site and the subjects of this analysis include: •

1 x Water Truck

•

2 x Bulldozers

•

2 x Excavators

•

1 x Sweeper Truck

•

1 x Idling Trucks at Weigh Station

•

1 x Clean Fill Haul Route Trucks

•

1 x Waste Fill Haul Route Trucks

These noise sources generate continuous steady state mechanical noise. There are no ground-borne vibration sources at the Facility as defined in NPC-207.

Characterization of the Existing Environment The SCRF is located in an area zoned as "Special Policy Area B", which has been identified as the Taro East Quarry Landfill. The surrounding area is made up of community park, open space, low density, high density, institutional and general commercial. The Facility is currently operating under ECA No. A181008. The Facility is located approximately 6 km southwest of Stoney Creek and 13 km southeast of Hamilton. The closest residential building is approximately 120 m from the Site and there are no other major industrial sources within the Study Area as indicated in Figure 2.1. The SCRF is a fully integrated facility that operates leachate processing equipment, storm water pond, retention pond and other small on-site equipment to move waste. The Facility is currently operating under an ECA that limits the Site to a maximum of 750,000 tonnes of waste per year and

a maximum of 250 vehicles entering the site per day. It should be noted that the maximum vehicles per day is much lower, with an average of 70-80 trucks per day. There are four roads located within the Study Area including: 1.

First Road West is a two-lane urban road with minimal local traffic only.

2.

Mud Street West is a four-lane road with dominant local traffic.

3.

Upper Centennial Parkway is a major four-lane road with significant 24-hour road traffic and is a major throughway for the City of Hamilton.

4.

Green Mountain Road West is a two-lane urban road with minimal local traffic only.

Green Mountain Road West and First Road West experience low traffic volumes as confirmed by the past traffic studies, as well as through the recent traffic survey undertaken by GHD on May 24, 2016 (further details provided in the Traffic Existing Conditions Report) . Mud Street West and Upper Centennial Parkway traffic volumes are elevated during the morning and evening rush hour period as confirmed by previous traffic studies.

4.1

Background Noise Study Results

Adjacent road traffic travelling along the Mud Street West and Upper Centennial parkway arterial roads are the predominant 24-hour ambient noise sources. The historical background noise studies indicated that the ambient one-hour Leq sound levels during the daytime periods ranged from 56 dBA to 63 dBA. Nighttime levels were not documented as the SCRF does not operate at night.

4.2

Semi-Annual Noise Monitoring Survey

A semi-annual noise monitoring survey was completed during 2012 to measure noise levels at the nearest receptors around the SCRF. In addition, road traffic noise modeling was completed. The survey results are documented in the Figure 4.1:

Figure 4.1 Noise Receptor Assessment


The annual noise monitoring report documented measured noise levels at the receivers around the SCRF (NR1-NR3) which included heavy contributions from adjacent road traffic. The existing Facility operations are predicted to be well below the predicted traffic impact.

Figure 4.2 Noise Measurement Receptors – Aerial Overview Figure 4.2 details the locations of the sensitive receptors around the Facility that were the subjects of the previous Acoustic Assessment Reports and the Annual Noise Monitoring Survey for the SCRF. Sensitive receiver NR4 has been added to evaluate the proposed residential development to


the North West along Green Mountain Road. The receivers are adjacent to major arterial roads that surround the Facility and have no blocked line-of-sight to roadways or landfill operations.

4.3

MOECC Technical Guidelines and Standards

On-site operations at the SCRF are compared directly against a daytime one-hour Leq sound level limit of 55 dBA for landfill operations that are limited to 7 a.m. to 7 p.m. under the "Noise Guidelines for Landfill Sites" (N-1). The acoustic character of the Study Area will be defined in accordance with the MOECC guidelines NPC-300 "Environmental Noise Guideline, Stationary and Transportation Sources – Approval and Planning," October 2013. As stated in the guideline: A "Class 1 Area" means an area with an acoustical environment typical of a major population centre, where the background noise is dominated by the urban hum. "Class 2 Area" means an area with an acoustical environment that has qualities representative of both Class 1 and Class 3 Areas, and in which a low ambient sound level, normally occurring only between 23:00 and 07:00 hours in Class 1 Areas, will typically be realized as early as 19:00 hours. Other characteristics which may indicate the presence of a Class 2 Area include: •

Absence of urban hum between 19:00 and 23:00 hours.

•

Evening background sound level defined by natural environment and infrequent human activity.

•

No clearly audible sound from stationary sources other than from those under impact assessment.

"Class 3 Area" means a rural area with an acoustical environment that is dominated by natural sounds having little or no road traffic, such as the following: •

A small community with less than 1000 population.

•

Agricultural area.

•

A rural recreational area such as a cottage or a resort area.

•

A wilderness area.

The Study Area is surrounded by urban land uses and is considered to be a urban Acoustic Class 1 Area.

4.4

Complaints

The Facility maintains a record of all environmental complaints received at the SCRF and has put in place the following standard procedures for responding to complaints: •

All complaints received will be assigned a control number and recorded electronically.

•

Details of the complaint are forwarded to Terrapure Management for follow-up.

•

Terrapure Management will send a confirmation letter to the complainant within 10 days of receiving the details.


•

Terrapure Management will ensure that the complaint is investigated and resolved in a timely manner.

•

Terrapure Management will be advised of the result of the investigation.

•

Terrapure Management will forward a letter or report to the complainant detailing the results of the investigation.

•

Terrapure Management will notify the Community Liaison Committee (CLC) via email of the complaint immediately after the investigation has been completed.

•

Complaints will be summarized for inclusion in the Annual Report.

A review of the complaint records from the past three years indicates that out of the 31 complaints, zero were related to noise perceived from the Facility. Table 4.1 Complaint Records Year

Concerned residents or businesses can call the Facility directly, the City of Hamilton, or the MOECC if a nuisance effect is perceived to have occurred because of the Facility. All complaints are recorded and investigated in accordance with the Facility standard complaint procedures and templates. Each complaint is logged and, in many cases, Site staff will go to the location where the nuisance was recorded and conduct on-site investigations. The date and time of the complaint are cross-referenced with data from the Facility in order to determine if any adjustments to operations need to be made at the Site. Each complaint received at the Facility is reported to the MOECC.
