Description

The objectives of the 2014 investigation and monitoring program were to: Evaluate the potential for vapour migration in residences in the area; Assess exposure and risk to residents in the vicinity through direct measurement of indoor air; Investigate the effects of seasonality on potential vapour intrusion, soil vapour concentrations and presents of NAPL; Evaluate if attenuation and if possible biodegradation is occurring between the source and residents; and where possible, delineate the extent of NAPL in the vicinity of monitoring well MW10-6 and further characterize soil and groundwater conditions in this area.

Description

This guidance outlines a methodology for air dispersion modelling that should be used to determine appropriate non-routine flaring management practices. It was developed to ensure consistency in the use of air dispersion models for regulatory applications in Alberta and is intended for flare operations that either require an Environmental Protection and Enhancement Act approval, that operate under a Code of Practice for emissions to the atmosphere, or where required by other regulatory agencies such as the Alberta Energy Regulator.

Description

The Remediation Certificate Regulation has been developed as a formal system of regulatory closure for sites that fall under Part 5 of the Environmental Protection and Enhancement Act. This legislation provides certainty to site owners, managers and other stakeholders involved with a contaminated site. It ensures that regulatory issues for a given release are no longer a concern under a given land use within a remediated area.

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

The Alberta government has developed a new reclamation program that is designed to strengthen the approach to contaminant management and enhances capacity needed to deal with an increasing workload in conventional oil and gas decommissioning. the old wellsite inquiry process has been replaced by a combination of technical review of applications and post-certification field audits. Use of specialists is encouraged for the first two years of the new program and, thereafter will be required.
