Ambient Monitoring Report – August 31, 2007 Ottawa Landfill – Ottawa, Ontario – Project W07-5256A Page 1

1. DESCRIPTION OF REPORT / SCOPE

This ambient monitoring report has been prepared in response to the requirements of

Provincial Officer’s Order Number 5830-6Z2PPW, issued on May 11, 2007 by Provincial

Officer Greg Davis. This report fulfills the requirements of Item No. 5 of this order, which

states:

“By no later than August 31, 2007, submit to the issuing Provincial Officer an Ambient

Air Monitoring Report with respect to the WMCC Landfill Site. The report shall be prepared by

the Qualified Person as a result of the Qualified Person having conducted the ambient air quality

monitoring, testing, and reporting set out in the Ambient Air Quality Work Plan as identified in

the February 16, 2007 letter prepared by RWDI AIR Inc. and attached to this Order as Appendix

I, with the amendment that the monitoring and testing be completed such that the final report

outlined in the 2nd paragraph on page 5 of the Plan is issued and submitted to the issuing

Provincial Officer by August 31, 2007. Make all efforts to notify the issuing Provincial Officer,

or if the officer is not available, Paul Kehoe, the Area Supervisor of the Ottawa District Office of

the Ministry of the Environment, at least 24 hours prior to each sampling event.”

This interim report has been issued to comply with the timeline outlined in the Provincial

Officer’s Order. A final report will be issued once all analytical results have been received.

RWDI AIR Inc. (RWDI) was retained by Waste Management Corporation of Canada

(WM) to conduct the ambient monitoring and to prepare the Ambient Monitoring Report on their

behalf.

2. OVERVIEW OF AMBIENT MEASUREMENT PROGRAM

Five days of ambient measurements were proposed. The sampling was conducted during

June, July, and August. The survey included five pairs of concurrent samples (ten in total) for

volatile organic compounds (VOCs). In addition, five pairs of samples were collected for

reduced sulphur compounds including hydrogen sulphide (H2S), mercaptans and Total Reduced

Ambient Monitoring Report – August 31, 2007 Page 2 Ottawa Landfill – Ottawa, Ontario – Project W07-5256A

Sulphur (TRS). A maximum of two sample days were allowed for each month. These surveys

included coincident sampling at locations both upwind and downwind from the facility. An on-

site meteorological station measured wind speed, wind direction, rainfall and ambient

temperature concurrently with the field measurements.

Short-term (1/2-hour) samples were taken. In order to best maintain the important

upwind and downwind positions, the sampling locations varied between sample days to adjust to

current meteorological conditions. The collected samples were sent for laboratory analysis and

the results were compared to the applicable MOE Point of Impingement (POI) Limits for 1/2-

hour samples. Sampling was conducted only during periods when the landfill is operating. The

samples were not taken within 48-hours of a significant rainfall (greater than 1 mm).

As of August 29, 2007, all of the proposed sample sets for VOCs and reduced sulphurs

have been collected. The final sample set, however, was collected on August 28, 2007.

Laboratory results have not yet been received for this final sample set. A final report will be

issued once these results have been received from the lab.

The last sample was collected so late in the proposed sampling period due to many of the

logistical challenges that beset the sampling campaign. As will be discussed in Section 3.2, TRS

bag samples have a very short shelf life and could only be analysed by laboratories in

Mississauga. As such, samples could only be collected from Monday to Thursday. This,

combined with the requirement to wait 48 hours after significant rainfall meant that there were

very few days available to collect the necessary samples.

2.1 Compounds of Interest

Table 1a, provided in the Tables section, contains a summary of the target list for VOCs,

as included in the Ambient Air Quality Work Plan. This target list contains 49 VOC compounds.

An additional 10 VOC compounds were included in the analysis at the lab. These additional

compounds are presented in Table 1b. The analytical results are presented for all 59 compounds

analysed.


Table 2a, provided in the Tables section, contains the proposed target list for reduced

sulphur compounds. The target list contains five reduced sulphur compounds. An additional 14

reduced sulphur compounds were included in some of the laboratory analyses. These additional

compounds are presented in Table 2b.

3. SAMPLING METHODOLOGY

A number of quality assurance measures were implemented throughout the program.

This section provides details with respect to samplers, media, methods and QA/QC procedures.

3.1 VOC Measurements

Ambient air samples were collected concurrently at locations directly downwind and

upwind of the landfill mound. In general, the downwind samples were focussed on capturing

emissions from the landfill operations. The sampling locations (upwind and downwind) were

pre-selected based on forecasts of wind direction provided by Environment Canada, information

from the on-site meteorological station, and any directives provided by the MOE.

The sampling methods and analytical techniques used for VOC sampling were developed

based on guidance from the MOE’s Operations Manual for Point Source Air Quality Monitoring.

Sampling for VOCs will be based on the U.S. EPA Ambient Air Method TO-17 using adsorbent

tubes. The VOC stainless steel (SS) adsorbent tube dimensions are 6.3 mm x 140 mm, and the

tube is packed with Carbotrap Y, Carbotrap X, Carboxen 569, and Carbosieve S-III. The tubes

were spiked with a deuterated vinyl chloride surrogate to demonstrate vinyl chloride recovery.

Air samples were collected by means of a diaphragm pump regulated with rotameters or mass

flow controllers. The sample flow rates were approximately 240 ml/minute, resulting in total

sample volumes of approximately 7.2 litres, as suggested by the MOE.


Exposed SS field tubes were returned to the laboratory for analysis. The analytical

methodology used by the laboratory is comparable to EPA SW846 Method 8260B, NIOSH

Method 2549 and equivalent to EPA Compendium Method TO-17. Calibration was achieved

using individual chemical response factors (TRFs) normalized against Toluene-d8.

In other landfill studies performed by RWDI, vinyl chloride has been found to be the

limiting contaminant in landfill gas, based on its source concentration and low POI limit. Since

it is typically limiting contaminant, vinyl chloride was analyzed separately in Single Ion Mode

(SIM), which has a lower method detection limit.

Media for VOC sampling and analysis of collected samples was provided by OSB Lab in

Mississauga, Ontario.

3.2 Reduced Sulphur Measurements

Reduced sulphur samples were collected in three-litre Tedlar bags at locations and times

concurrent with the VOC samples. The samples were collected over a ½ - hour period. Once

collected, the reduced sulphur samples were placed within a black plastic bag or cardboard box

to limit destruction of the compounds by exposure to light. The samples were sent to an

accredited laboratory and analysed using gas chromatography / flame photometric detection.

Wherever possible, the samples were analysed within 24-hours of collection. Analyses were

rejected from reporting if they were analysed more than 72 hours after collection.

Analysis of the Tedlar bags had been originally contracted to Maxxam Analytics Inc. in

Mississauga until it was found (following the receipt of the first set of results on June 20) that

Maxxam’s analytical method had a detection limit that was above the MOE POI limit for these

species. Subsequently, Tedlar bags were submitted to Air Zone One in Mississauga for analysis.


3.3 Meteorological Station

Continuous wind speed, wind direction, ambient temperature, and relative humidity

measurements were collected from the on-site weather station during the sampling program.

Five-minute averages for wind speed and wind direction were collected during the 1/2-hour

samples.

3.4 Quality Assurance Measures

A number of common quality assurance measures were implemented during the sampling

program to ensure the integrity of the results. These measures included detailed documentation

of all field activities, calibration of all samplers, the use of sample blanks, and a number of

laboratory-related measures including sample handling procedures, and instrument calibrations.

All of the samplers were bench-tested and calibrated in RWDI’s office prior to field

deployment and calibrated again in the field before and after use. For example, all of the low

flow samplers were calibrated against a certified primary dry cell standard, (i.e., dry cell

calibrator) before and after sampling.

Chain of Custody forms were completed and submitted along with the exposed samples

to the laboratory. Where required by the method, exposed samples were packed in coolers

before transport.

3.5 Relevant Air Quality Limits

Measured 1/2-hour VOC and reduced sulphur compound concentrations from the

ambient air quality monitoring program were compared to their respective Ontario Regulation

419/05 POI Limits. Regulation 419/05 sets forth explicit standards for a source’s contribution to

the concentration of airborne contaminants at the POI. The term POI is taken to be in the natural

environment at the boundaries of the property. Based on the 1/2-hour VOC sample duration, the

1/2-hour POI Limits can be used as a comparison to determine off-site impacts, if any.


4. RESULTS

Four VOC sample sets have been collected and analyzed by the laboratory. Five reduced

sulphur sample sets have been collected and analyzed by the laboratory. The samples were

collected on the following days:

June 11, 2007: VOC and TRS;

June 19, 2007: TRS;

July 7, 2007: VOC and TRS;

July 23, 2007: VOC and TRS;

August 20, 2007: VOC and TRS;

August 22, 2007: TRS only.

Due to scheduling issues with the analytical equipment, the TRS samples collected on

July 23rd were not analyzed by the laboratory until >96 hours after sampling. Therefore, the

results of the TRS analysis may not be accurate for this date. For this reason, these TRS results

were excluded from the analysis.

The results of the VOC samples are presented in Tables 3 to 6. The results of the TRS

samples are presented in Tables 7 to 11. These tables include the following information:

For VOCs, a summary of all measured data, in terms of upwind, downwind, and blank

sample tube results in total nanograms (ng) as well as upwind and downwind results in

terms of concentration, in micrograms of contaminant per cubic metre of air (ug/m3).

For TRS, a summary of all measured data, in terms of upwind and downwind results in

parts per million as well as in micrograms of contaminant per cubic metre of air (ug/m3).

Comparison of upwind and downwind measured concentrations to the applicable air

quality limits.

A comparison of the upwind and downwind measured concentrations to determine the net

impacts from the landfill facility.


Figures 1 to 6 illustrate the precise sampling location and include a wind rose

representing the meteorological conditions occurring at the site during each sample day.

In all cases, the measured concentrations were less than the applicable POI Limits. All

samples were collected on the landfill property; therefore, off-site impacts are expected to be

even lower than the measured amounts.

The remaining VOC sample was collected on August 28, 2007. This sample was sent to

the laboratory for analysis; however, analytical results have not yet been received. An updated

report will be submitted once the results of the August 28th sampling are received from the

laboratory.

5. SUMMARY

Overall, all of the measured results were found to be less than the relevant POI Limits.

The maximum measured downwind concentrations and maximum net landfill impact for VOCs

are presented in Table 12. The maximum measured downwind concentrations and maximum

net landfill impact for TRS compounds are presented in Table 13. All of these maximum

concentrations were less than the applicable POI Limits.

6. CONCLUSION

None of the ambient measurements resulted in concentrations that were greater than the

relevant POI Limits; therefore, the Ottawa Landfill is expected to be in compliance with all Reg.

419/05 requirements.
