Air quality monitoring in the vicinity of a CNRL well blowout : February 25, 2010 to March 9, 2010 summary report

Description

All monitoring sites were downwind of the CNRL natural gas well blowout, except Site G which was a background site. A one-hour AAAQO for hydrogen sulphide of 0.010 ppm was no exceeded. The maximum... More ≫

Description

All monitoring sites were downwind of the CNRL natural gas well blowout, except Site G which was a background site. A one-hour AAAQO for hydrogen sulphide of 0.010 ppm was no exceeded. The maximum one-hour average for hydrogen sulphide of 0.001 ppm was measured at both Site G, the background site, and Site H. These were the only two sites were hydrogen sulphide was above the detection limit. The highest one hour total reduced sulphur concentration of 0.002 ppm as measured at Site E.

Description

Odour complaints from the Three Creeks area were received by the Energy Resources Conservation Board and Alberta Environment. Odours were noted when the wind speed was low, and it is likely that this meteorological condition contributed to the accumulation of emitted compounds in the area. The odours in the area were identified as "hydrocarbon type" and air samples were collected at various locations within the affected area, at the potential source locations, and also at background (reference) sites. These samples were taken to a laboratory and analyzed for volatile organic compounds (also known as hydrocarbons).

Description

A study was initiated to evaluate the concentration of fine particulate matter (PM2.5) at two sites in Sherwood Park, east of Edmonton. The data presented in this report were collected between January 2008 and January 2009. Overall, particulate concentrations at the two sites were comparable. Concentrations were generally higher during the winter months and for periods of low wind speeds.

Description

The wood waste burner operated by Tolko forest Products is located within the town limits of High Level. The current study investigates the quality of air in the area with a special focus on particulate matter. Although a wide size range of particles can be emitted by wood burning, the current study focused on concentrations of fine particulate matter. The concentration of particulate matter was monitored at one location for five and a half months, beginning in October 2008. In addition, the department's mobile laboratory was used to monitor a suite of gases and particles at various sites in and near the town. This was performed on two days at the start of the study.

Description

A short monitoring survey was conducted in the Bonanza area, northwest of Grande Prairie near the British Columbia border, to evaluate the quality of air. Landowners are concerned about the impact of oil and gas activity on air quality in the area. As a result, this report focuses on pollutants typically associated with such activities. The survey was conducted using Alberta Environment's Mobile Air Quality Monitoring Laboratory. Samples were collected on two days in February 2009.

Description

A study was initiated to evaluate the concentration of fine particulate matter in Sherwood Park, east of Edmonton. The data presented in this interim report were collected between January and June 2008, at two monitoring sites. Overall, the particulate concentrations at two sites were comparable. Concentrations were generally higher during the winter months and for periods with low wind speeds. This is likely due to a larger semi-volatile fraction forming the sampled particles and/or lower mixing height during the winter months resulting in higher ground level concentrations.

Description

In June 2007, Alberta Environment introduced the Alberta Tier 1 Soil and Groundwater Remediation Guidelines (AENV 2007a), and the Alberta Tier 2 Soil and Groundwater Remediation Guidelines (AENV 2007b) at workshops in Edmonton and Calgary, Alberta. Workshop participants provided questions to the presenters to answer verbally during the sessions. For the benefit of the workshop attendees and others who are interested in the workshop material, these questions and answers have been drafted into this document. Other frequently asked questions on the proposed remediation certificate program have been included to provide readers with a broader scope of information.
