1.0 SAMPLING PROGRAM OVERVIEW

Wood Environment & Infrastructure Solutions, a Division of Wood Canada Limited (Wood) was

retained by Vale Canada Limited’s (Vale) to operate and maintain the ambient air sampling

stations, to review the data, and to prepare quarterly and annual reports on behalf of Vale. There

are nine stations that were established for monitoring ambient air concentrations for Total

Suspended Particulate (TSP), Inhalable Particulate Matter (PM10) and metals on both the TSP and

PM10 size fractions.

The results of the First Quarter (Q1) 2019 sampling program are detailed in this report.

Vale’s Total Suspended Particulate (TSP) Hi-Vol ambient air monitoring stations operate on a

3-day sampling schedule at the following stations: Dynamic Earth, Norite Street, Venice Street,

Copper Cliff Creek, Union Street, Spruce Street, Delki Dozzi, Power Street and more recently,

Fielding Road. The Fielding Road monitoring station was added to the sampling program on

17 August 2017. All TSP samples (filters) are subsequently analyzed for speciated metals. For the

purposes of this report, TSP is synonymous with Suspended Particulate Matter (SP) with a

particle size of 44 microns or less for which the AAQC is established, and consistent with the

terminology of the MECP Operations Manual for Air Quality Monitoring in Ontario.

The PM10 Hi-Vol ambient air monitors are co-located at the Dynamic Earth, Norite Street,

Venice Street, Copper Cliff Creek and Union Street stations. These monitors operate on a 6-day

sampling schedule. All PM10 samples (filters) are analyzed for speciated metals.

The metals analyzed in both size fractions include arsenic, cadmium, chromium, cobalt, copper,

iron, lead, manganese, nickel, selenium, vanadium and zinc. The analysis also includes sulphur.

Each sample is collected over a 24-hour period (midnight to midnight) that is concurrent to the

National Air Pollution Surveillance (NAPS) schedule.

2.0 SAMPLING RESULTS

The results of the samples at each of the nine (9) monitoring sites are presented in the following

section. Table 1 outlines the data recovery efficiencies of each site (all monitors combined).

Total 345 336 97

During this quarter, a total of 336 valid samples were collected from a possible total of

345 samples, and the overall sample recovery for the quarter was 97%.

A total of 9 samples were invalidated:

• One (1) sample was lost due to invalid flow at Copper Cliff Creek Station;

• Four (4) samples were lost due to operator error, one at each of Power Street,

Union Street, Copper Cliff Creek Station, and Spruce Street;

• Four (4) samples were lost due to equipment failure at Union Street (2), and Venice

Street (2).

The invalid samples are identified in the Appendix A summary tables.

Measured TSP results were compared to their applicable Air Contaminant Benchmarks, which

are the Schedule 3 Standards under O.Reg. 419/05 and Guidelines, as per the Ministry of the

Environment, Conservation and Parks (MECP)1 document entitled Air Contaminants Benchmarks

List: Standards, Guidelines and Screening Levels for Assessing Point of Impingement

Concentrations of Air Contaminants published January 2017. The PM10 size fraction was

compared to the interim ambient air quality criterion (AAQC).

1 The Ministry was renamed MECP in July 2019, and is the former Ministry of the Environment and Climate Change (MOECC)



Table 2 outlines the statistics for the collected samples from each site and particulate size

fraction. A full summary of the Q1 results (from all samples) is provided in Appendix A of the

report.

Please note that all iron (total) results have been conservatively expressed as ferric oxide (Fe2O3),

since it is difficult to determine the amount of iron that has been oxidized. Iron is generally not

present as metallic iron, and a portion of the metallic iron is expected to be in the oxidized Fe2O3

form. Therefore, the iron results are conservatively compared to the Fe2O3 Schedule 3 standard

for information purposes only.



Furthermore, as of 1 July 2016 the site-specific standard and Schedule 3 standards for Nickel (Ni)

have changed. The new site-specific standard for Ni is 1.0 µg/m3, which applies to all smelter

related sampling stations (i.e. all stations except Power Street and Fielding Road). The new

Schedule 3 Standard is 0.04 µg/m3 which applies to the Power Street and Fielding Road

monitoring stations that are sited to monitor the Nickel Refinery. Both standards are based on

annual averaging times instead of the 24-hour averaging times.

The collected quarterly 24-hour data is conservatively being compared to the new annual

standards for information purposes only, and the Power Street Ni concentrations are compared

to the 24-hour AAQC of 0.2 µg/m3.

There was one TSP exceedance of the Schedule 3 Standard on 12 January at Dynamic Earth

Station. Vale has determined that this was caused by off-site sources such as roads after reviewing the SEM analysis, wind direction as well as wind speeds. There were no other exceedances of Schedule 3 Standards, Section 20 guidelines, or Schedule 6 URTs listed in

O.Reg.419/05.

Wood staff performed a flow calibration check on the air samplers on 28 March 2019, using a

BGI direct reading Hi-Vol electronic flow calibrator. The calibrator was received from the

manufacturer certified to an overall accuracy of 0.60%. A copy of the calibration certificate is

provided in Appendix B. All samplers were found to operate within acceptable tolerances at the

time of the calibration.

(1) Ferric oxide values are presented for informational purposes only; ferric oxide was calculated from elemental iron (total Fe) assuming the Fe to be oxidized

A "-" in the Fe(Fe2O3) indicates there was a ND for Fe for that sample and thus a value for Fe(Fe2O3) can not be calculated.
