AER: OneStop Update: Remediation and Reclamation Submissions Now Linked to Asset
Currently, submissions in OneStop for environmental site assessments, records of site condition, and other remediation and reclamation applications for an oil and gas asset are linked to the operator’s business associate identification (BA ID) and not to an asset.
Effective with the June 26, 2024, OneStop update, the following submission types will be linked to an asset in OneStop and not the BA ID:
- phase 1 environmental site assessments
- phase 2/3 environmental site assessments
- records of site condition
- reclamation certificate variances
- reclamation certificate applications
Following the change, when an asset is sold or transferred, the new operator can access submissions from the previous operator, saving time and money and reducing duplication of effort, preserving the history of site assessment, remediation, or reclamation work undertaken on the assets.
If you have any questions about OneStop or this bulletin, please contact our Customer Contact Centre at 403-297-8311 (toll-free 1-855-297-8311) or inquiries@aer.ca.
AER: Facility Life-Cycle Status Changes
The AER has made several changes concerning how facility life-cycle statuses are determined, which affects the determination of inactive liability. Updated facility life-cycle statuses and how they are determined will be available to licensees in the OneStop liability assessment report.
Update on Unknown Facility Statuses
Bulletin 2023-34: Validating Facility Operational Life-Cycle Statuses outlined that facilities with an “Authorization Life-Cycle Status” of “unknown” would be considered inactive and included in the licensee’s assessed inactive liability. This update was made effective April 2024. For information on how to update the facility life-cycle status, please refer to the bulletin.
Changing Facility Life-Cycle Priority Logic
One of the business rules used to determine a facility’s life-cycle status (whether it is active or inactive) comes from activity reported at Petrinex reporting facility IDs. Where a facility licence is linked to multiple Petrinex reporting facility IDs, the AER applies business rules to determine the facility life-cycle status. The previous business rules resulted in classifying some active facilities as inactive.
We have changed the business rules so that if any reporting facility ID other than a gathering system is active, the facility licence is considered active.
Publishing Facility Life-Cycle Logic
To create greater transparency, we have created a logic chart that outlines how the AER determines the life-cycle status of facility licences. This chart will be available to licensees in the OneStop liability assessment report next week.
AER issues corporate abandonment order to Tallahassee Exploration Inc.
CALGARY, AB, June 10, 2024 – On June 5, the Alberta Energy Regulator issued a corporate abandonment order to Tallahassee Exploration Inc., requiring the company to decommission its sites and submit and implement an approved reclamation plan.
The order comes in response to Tallahassee’s failure to comply with two previous orders, issued in September and November 2023.
On September 15, 2023, the AER issued a reasonable care and measures (RCAM) order to Tallahassee, citing concerns about a lack of reasonable care and measures to prevent impairment or damage to its sites. Tallahassee was directed to ensure reasonable care and measures at all sites, address outstanding noncompliances, and submit plans, including an RCAM plan and an abandonment plan for mineral lease-expired wells.
Despite submitting plans, Tallahassee failed to fully comply with the September order. In response, on November 27, 2023, the AER rescinded the September order and issued a new RCAM, directing the Orphan Well Association (OWA) to ensure reasonable care and measures at all Tallahassee-licensed sites.
Tallahassee was required to comply with the terms of the November order, including providing a plan detailing how it planned to transition custody of its assets from the OWA, reimburse the OWA for costs incurred, come into compliance with the 2022 closure spend quota, and action the previously approved abandonment plan for mineral lease-expired wells.
Following Tallahassee’s submissions and failure to comply with certain requirements of the November order, Tallahassee has not demonstrated it is capable of providing reasonable care and measures to protect public safety and the environment and is unable to meet its regulatory and end-of-life obligations. Consequently, the OWA retains care and custody of Tallahassee’s sites, and Tallahassee must obtain approval from the OWA before accessing and commencing any decommissioning work on the sites. Tallahassee will remain the licensee of record.
Alberta oil and gas sector exceeded flaring limit in 2023, data shows
(Source: Canadian Press) CALGARY — For the first time, Alberta’s oil and gas industry has exceeded the province’s own regulatory limit for natural gas flaring.
A tally by The Canadian Press of Alberta Energy Regulator data shows oil and gas companies in the province flared approximately 754 million cubic metres of natural gas last year, exceeding the annual provincial limit of 670 million cubic metres.
Flaring refers to the practice of burning off the excess natural gas associated with oil production. Though it is better for the environment than some other methods of gas disposal, it still releases harmful substances into the atmosphere.
The AER declined to comment on the findings, referring questions about possible penalties or other actions to the provincial government instead. But a 2022 report by the regulator on oil and gas emissions shows flaring volumes in Alberta have been increasing since 2016 and nudged close to the regulatory limit in 2022.
In that report, the AER said it “expects flaring to continue to increase” in the future, even as the regulations themselves aim to have the oil and gas sector “continue to reduce” the volume of flare gas released.
Natural gas is a byproduct that comes to the surface when companies drill oil wells. If the volumes of gas are small, and there are no pipelines nearby to transport the gas, companies often choose for economic reasons to dispose of it through flaring.
Flaring can also occur for safety reasons, to reduce sudden pressure increases at well sites.
Flaring volumes have been rising in part due to growing oil output in Alberta. But companies have also been turning increasingly to flaring in order to reduce venting, a term that refers to the direct release of unburned methane into the atmosphere from an oil or gas facility.
From an environmental perspective, flaring is considered preferable to venting. The methane released through venting is an extremely potent greenhouse gas, with even more heat-trapping potential than carbon dioxide.
Reducing methane emissions from oil and gas production is a stated priority for both the federal and provincial governments. And in fact, Alberta’s oil and gas methane emissions are estimated to have been reduced by approximately 45 per cent between 2014 and 2022, according to the AER.
But flaring isn’t harmless, either. While the combustion process involved in flaring reduces the amount of methane released significantly, flaring still releases a variety of byproducts and greenhouse gases into the atmosphere, including carbon dioxide, according to oil and gas data provider Enverus.
It also produces black soot which negatively impacts air quality and may pose a risk to human health, said Amanda Bryant, a senior oil and gas analyst with clean energy think-tank The Pembina Institute.
“Flaring as a form of mitigation just replaces one set of problems with another set of problems,” Bryant said.
“There’s also no reason why industry should be exceeding the limits, when there are alternatives available.”
She said these alternatives include the installation of a vapour recovery unit, which can be used to capture flare gases and redirect them back into production for use as fuel.
Other alternatives include compressing the natural gas and trucking it short distances to use as fuel off-site, or converting the gas to electric power using small-scale generators.
The Canadian Association of Petroleum Producers declined to comment on the industry’s increasing flare volumes.
In an emailed statement, Ryan Fournier, press secretary for Alberta Environment Minister Rebecca Schulz, said because the industry exceeded the provincial limit, the Alberta Energy Regulator has instructed the 20 highest flaring operators to create detailed plans to reduce flaring at their sites.
He said while reducing flaring is important, reducing overall methane emissions from the oil and gas sector remains the bigger goal.
“We are also now reviewing Alberta’s flaring policies, first established back in 2002, to see if updates are needed,” Fournier said.
Worldwide, there is growing pressure on oil and gas producers to reduce both flaring and venting.
The U.S. Department of Energy says both practices represent “significant challenges” for operators and regulators, who must work together to bring down oil and gas emissions.
The World Bank calls the practice of flaring “wasteful and polluting” and has identified the need to reduce flaring volumes globally as an urgent problem. The World Bank has also pointed to recent scientific studies that suggest more methane may escape into the atmosphere during the flaring process than previously assumed, suggesting the greenhouse gas impact from flaring could be underestimated.
In Canada, the federal government’s updated draft methane regulations — which aim to reduce oil and gas methane emissions by at least 75 per cent from 2012 levels by 2030 — say any flaring not being conducted for safety reasons will need to be supported by an engineering study that demonstrates a lack of other alternatives.
Bryant said Canada needs not only strong policy, but strong enforcement, to ensure Canada’s oil and gas sector keeps up with global efforts to reduce flaring.
But Julia Yuan, a PhD student with the University of Calgary’s department of chemical and petroleum engineering, said if increased flaring is a byproduct of less venting and overall methane emissions from oil and gas production, then it may be something society needs to accept for now.
“Perhaps flaring isn’t that bad of an alternative — at least at this point in time when we’re just trying to do as much (on climate change) as we can as soon as possible,” Yuan said.
“Because time is of the essence.”
Taku River Tlingit First Nation, B.C., Teck advance Tulsequah remediation
The Province of British Columbia, Teck Resources Limited (Teck) and the Taku River Tlingit First Nation (TRTFN) are taking a collaborative approach to jointly advance remediation of the former Tulsequah Chief Mine site.
“The Taku River Tlingit First Nation is committed to ensuring the Tulsequah Chief Mine is remediated and restored to natural conditions, according to Tlingit values and cultural principles of environmental stewardship,” said Charmaine Thom, spokesperson for Taku River Tlingit First Nation. “Tlingit culture teaches us to care for the land, to allow for traditional ways of life to continue in perpetuity, and to subsequently protect the natural environment, for future generations, and for all living beings who call our land their home. The co-operative partnership between the Government of British Columbia, Teck, and TRTFN reinforces the collective commitment to clean abandoned mines to an acceptable condition that meets the standard of both governments, this is an important step toward reconciliation.”
Under this approach, Teck will voluntarily undertake and fund site investigation work in 2024-25. Teck will also lead implementation of the final closure plan. The 2024-25 work will include establishing safe site access, assessing underground mine conditions, monitoring water quality and flow, and evaluating waste rock disposal sites. This work will inform the final Tulsequah Reclamation and Closure Plan, which is being co-developed by Teck and the TRTFN, guided by the TRTFN’s vision for their future use of the restored site.
“We look forward to continue working co-operatively with the Province and Taku River Tlingit First Nation to advance remediation of the Tulsequah Chief Mine site,” said Scott Maloney, vice-president environment, Teck, “While Teck has not been the owner of Tulsequah for some time, we recognize the importance of all parties working together to progress remediation of this historic site, in support of reconciliation and sustainability, and as a reflection of the best practices of today’s modern, responsible mining sector in B.C.”
British Columbia has high reclamation standards, encouraging all mining companies to act responsibly and to meet their reclamation obligations. The Province will work with Teck and the TRTFN to enable the efficient implementation of this approach under B.C.’s regulatory framework. This work will help to protect the Tulsequah River, enable the land to be restored as quickly as possible for the TRTFN’s beneficial use and ensure TRTFN rights and laws are incorporated into reclamation planning at Tulsequah.
“We are committed to ensuring the Tulsequah Chief Mine site is cleaned up in accordance with the Province’s high environmental standards,” said Josie Osborne, Minister of Energy, Mines and Low Carbon Innovation. “I am grateful for the clear vision and purpose of the Taku River Tlingit First Nation in restoring this site, and I commend Teck for embarking on the necessary collaborative work with TRTFN and the Province. I look forward to seeing this significant endeavour progress.”
This collective approach is underpinned by the Province’s strong environmental assessment, permitting, reclamation and compliance and enforcement requirements that seek to ensure that all mining projects are planned, operated and closed safely in an environmentally sound way.
Quick Fact:
- Tulsequah Chief Mine site, located within TRTFN territory approximately 100 kilometres southwest of Atlin, is a historic underground copper, lead and zinc mine, which was operated from 1951-57 by a predecessor company to Teck and is currently owned by Chieftain Metals Inc.

B.C. coal mining company fined for more than 400 violations
(Source: CBC News) A B.C. coal mining company in northeastern B.C. has been fined more than $45,000 for repeated violations of the province’s environmental protection rules, including the failure to monitor mine waste into fish-bearing water and failure to limit particulate being put into the air.
Conuma Resources Limited is a metallurgical coal mining company operating in the Tumbler Ridge area in northeastern B.C., roughly 660 kilometres directly northeast of Vancouver.
It mines coal to produce carbon used in steelmaking at three different sites in the region, employing approximately 900 people.
In documents posted online, the B.C. Ministry of Environment and Climate Change argued the company repeatedly and knowingly failed to comply with environmental regulations, limiting the amount of particulate put into the air by mining operations, and failed to monitor waste water put into local waterways on more than 400 separate occasions.
The violations were said to have occurred at the company’s Brule Mine site between 2020 and 2023, after Conuma had already received several notices and warnings for previous violations, the report says.
The total penalties amount to $45,850 and must be paid within 30 days of receipt.
On the issue of particulate, a report from the ministry says Conuma has failed to properly set up its operations to prevent excessive amounts of dust and discharge from entering the surrounding air, exceeding provincial limits on dozens of occasions over multiple years.
However, the company argued that wildfires in the region, as well as slash-burning from nearby forestry operations, were also contributing factors and it should not be held solely responsible.
Environmental Management Act director Jason Bourgeois agreed, and removed some of violations from the final ruling.
However, he did rule that Conuma did violate the rules on multiple other occasions, despite warnings, and ordered a total penalty for air quality violations of $4,750, down from the original $22,000 initially proposed by the ministry.
Conuma was not as successful in reducing its penalty for its failure to comply with water monitoring, which was ruled to have occurred on 406 separate dates between Oct. 21, 2020 and Jan. 1 2023, for which Bourgeois applied a base penalty of $10,000.
Conuma discharges effluent from its operations into ponds that lead into creeks and a river that are home to several species of fish. As a result, it is supposed to sample toxin levels from its operations, have them be tested for compliance and regularly share that information with provincial officials.
The ministry reported and Bourgeois agreed that Conuma had failed to follow these rules multiple times over several years.
Bourgeois ruled that while Conuma has since taken some steps to comply with the rules, they had repeatedly failed to collect and test samples, despite knowing they were meant to do so. For this, he added an additional penalty of $3,000.
He also agreed with the ministry report that Conuma benefited economically from this, by not having to pay for the labour or shipping costs associated with the work. For this, he applied an additional penalty of $32,700.
Another $3,000 was deducted for the work Conuma has done since to address the violations, for a total of $42,700, adjusted down to the maximum penalty of $40,000 for water monitoring violations.
Bourgeois also noted that he could have applied a $40,000 fine to each of the violations but opted to lump them together as it was the first ruling against the company.
On top of the air quality and water monitoring fines, an additional $1,100 fine was issued for failure to submit monthly reports and upload data on water quality monitoring.
The Government of Canada introduces new measures to regulate methane emissions from Canadian landfills
Methane is a potent greenhouse gas with 28 times more global warming potential than carbon dioxide over a 100-year period. Reducing methane emissions from all sources, including landfills, is one of the fastest and most cost-effective ways to combat climate change.
That is why, today, the Honourable Steven Guilbeault, Minister of Environment and Climate Change, announced the publication of the proposed Regulations Respecting the Reduction in the Release of Methane (Waste Sector). The proposed Regulations would require landfills to control methane emissions and ensure landfill gas-recovery systems capture as much methane as possible.
The proposed Regulations would provide a consistent regulatory approach to reduce landfill methane emissions across the country in publicly- and privately-owned landfills that have received municipal solid waste. More specifically, owners and operators of regulated landfills that are estimated to generate methane above regulation thresholds would be required to comply with and monitor methane concentration limits on the landfill surface, limit venting of methane to the atmosphere, and detect and repair methane leaks.
To help assist with compliance costs that some landfills may incur, the Canada Community-Building Fund provides $2.4 billion in funding every year to provinces and territories who, in turn, distribute this funding to communities for strategic investments in essential infrastructure, including solid waste management infrastructure. This funding could support communities who develop landfill gas management infrastructure projects to comply with the proposed Regulations.
The proposed Regulations would aim to reduce methane emissions from Canadian landfills by about 50 percent by 2030 (from 2019 levels). The proposed Regulations would contribute to Canada’s commitment to reducing global methane emissions by at least 30 percent below 2020 levels under the Global Methane Pledge. They would also help Canada reach its emissions reduction target of 40–45 percent below 2005 levels by 2030 and net-zero emissions by 2050. Stakeholders, interested parties, and Canadians are invited to review the proposed Regulations and provide feedback by August 28, 2024.
“Reducing emissions from methane is one of the top recommendations made by climate scientists to slow the rate of global warming. To achieve Canada’s emissions reduction targets, we need to reduce landfill methane emissions. The proposed Regulations would set standards that are in line with the most stringent requirements in North America.”
– The Honourable Steven Guilbeault, Minister of Environment and Climate Change
Quick facts
Globally, methane is responsible for around 30 percent of the global rise in temperatures to date.
Landfills account for 17 percent of Canada’s methane emissions and 3 percent of its greenhouse gas emissions.
In October 2021, Canada announced support for the Global Methane Pledge, which aims to reduce global methane emissions by 30 percent below 2020 levels by 2030.
The Government of Canada consulted Canadians on how to regulate to reduce methane emissions from landfills by publishing a discussion paper in January 2022. A What We Heard Report was published in September 2022.
In April 2023, the Government published a Proposed Regulatory Framework to seek comments, which were used to finalize the proposed Regulations.

Emergency order to protect boreal caribou habitat in Quebec
Boreal Caribou—also known as Forest-dwelling Caribou in Quebec—are an iconic Canadian species that is intimately connected to the culture, history, and traditions of Indigenous peoples. Formerly abundant, the population in Canada is now estimated to be less than 34,000 individuals. According to data, the species is declining in many parts of the country. Boreal Caribou have been listed as threatened in Canada since 2003, meaning the species could become extinct if nothing is done to protect it.
Implementation of an emergency order in Quebec
While the provinces and territories have primary responsibility for managing land and wildlife within their jurisdictions, the Species at Risk Act includes provisions designed to protect species at risk and their habitats on non-federal lands. This is particularly the case of section 80, which stipulates that the Minister of Environment and Climate Change has an obligation to recommend to the Governor in Council that an emergency order be made if the Minister is of the opinion that a species faces imminent threats to its survival or recovery.
At the recommendation of the Minister of Environment and Climate Change, the Government of Canada is taking steps to make an emergency order to address the imminent threats faced by the three most at-risk Boreal Caribou populations in Quebec, namely those in Val-d’Or, Charlevoix, and Pipmuacan. The populations in Val-d’Or and Charlevoix, with 9 and 30 individuals, respectively, live in enclosures year-round. The population in Val-d’Or has already crossed the threshold of quasi-extinction, and the one in Charlevoix is very close to reaching it. With less than 300 individuals, the Pipmuacan population could cross the threshold in around 10 years.
In the coming weeks, the Government of Canada will consult with the Government of Quebec, Quebec’s Indigenous communities, the public, stakeholders, and interested parties, including local communities and industries, on the scope of potential protection areas and proposed prohibitions that would apply in these areas. Following the consultations, the order will be finalized. The order is a regulation that, once approved by the Governor in Council, will protect targeted areas of best available habitat on Quebec provincial lands for the Val-d’Or, Charlevoix, and Pipmuacan populations. The imminent threats to recovery are due to the increase in the scope of disturbance from multiple threats, in particular the impact of logging for industrial activities and road network expansions. The order will prohibit activities that contribute to these imminent threats. Under the Species at Risk Act, if Quebec were to implement concrete protection measures leading the Minister to conclude that the species was no longer facing imminent threats to its recovery, the Governor in Council could, at the Minister’s recommendation, withdraw the order.
The tabling of the Quebec strategy for Boreal and Mountain Caribou has been postponed repeatedly in recent years. Although two pilot projects were recently announced, the Government of Quebec has not submitted a comprehensive strategy, and the species continues to face imminent threats to its recovery.
Boreal Caribou in Quebec and Canada
With approximately 15 percent of Canada’s Boreal Caribou population, Quebec plays a major role in the species’ recovery. In 2023, the Quebec government estimated the Boreal Caribou population to be between 6,162 and 7,445 individuals. The majority of Quebec’s populations are declining, one of the main reasons being the loss or alteration of caribou habitat.
An important species to the boreal forest
Boreal Caribou are an important part of the boreal forest ecosystem. Boreal Caribou tend to avoid disturbed areas, and thus their movement pattern and population status can help us understand more about the overall health of the boreal forest. Protecting the species’ habitat can have significant co-benefits for other species at risk, plants and wildlife, and biodiversity in general. For example, protecting Boreal Caribou habitat across Canada could improve outcomes for 90 percent of the bird and mammal species that live in the boreal forest, and protect soil carbon storage hotspots.
Threats
Boreal Caribou populations have declined significantly across Canada over the last few decades. This is due in large part to increased predation linked to human-caused habitat disturbance. Caribou need large patches of mature and old-growth forests. Older forests allow caribou to separate themselves from their predators. Habitat disturbances include use of land by industry such as forestry, mining, oil and gas development, and “linear features” like roads. There are also natural disturbances to Boreal Caribou habitat, such as forest fires and insect outbreaks. Natural and human disturbances can lead to younger stands of trees, which tend to attract other prey such as moose and deer. These animals can carry diseases that threaten Boreal Caribou and can also increase the number of predators, such as bears and wolves, in caribou habitat. Disturbed habitats, including multi-use roads, can make it easier for predators to travel through caribou habitat, increasing the chances that predators encounter caribou.
Climate change may also have long-term effects on Boreal Caribou. The effects of climate change are expected to increase the impacts of natural and human disturbances on Boreal Caribou and their habitat. Like disturbances, less severe winters and increasing proportions of hardwood trees in the southern portions of the boreal forest could increase the abundance of deer, moose, and predators in the North, thus contributing to the decline of Boreal Caribou distribution. In addition, warmer and drier conditions are expected to increase the frequency and magnitude of fires in Canada’s boreal forest, adding to overall disturbance levels.
Coal mine contaminants blown onto snowpack in Alta., B.C.: study
(Source: Canadian Press) Cancer-causing chemicals are being blown downwind from coal mines in southern British Columbia in concentrations that rival those next to oilsand mines, newly published research has concluded.
“Our results reveal, for the first time, clear evidence that coal mining contaminants are spread far downwind from their sources,” says the paper, published in the journal Environmental Science and Technology.
The research, conducted by scientists from the Alberta government and the University of Alberta, studied the snowpack around four coal mines in British Columbia’s Elk Valley. They sampled 23 sites at varying distances from the mines in 2022 and 2023, melting a surface-to-ground column of snow and analyzing the results.
“In a winter snowpack, you’re capturing everything that’s being deposited as long as that snowpack is on the ground,” said Kira Holland, a University of Alberta postgraduate researcher. “It provides an amazing record for a season.”
When analyzed, the melted snow proved high in polycyclic aromatic compounds, a class of chemicals closely associated with fossil fuels. So-called PACs are considered to cause cancer as well as damage the liver and immune system.
Their distribution in the snowpack matched prevailing wind patterns, with samples nearer a mine yielding higher levels, and their composition matched that found in Elk Valley coal.
“We found the snowpack had particularly high PACs,” Holland said. “The pattern of deposition looks like very high concentration near these mining sites that decrease with distance.”
Alberta’s environmental guidelines for PACs in rivers and lakes range between .015 micrograms and 5.8 micrograms per litre of water, depending on the specific chemical.
One site in the study recorded 100 micrograms per litre. Another six sites showed at least 10 micrograms and seven showed at least one microgram.
Those levels are in the same range as those found adjacent to oilsands mines in northern Alberta, Holland said.
“The magnitude of the deposition is similar.”
The study also considered how far the chemicals might travel. Using airshed modelling, it suggests the PACs could be travelling more than 100 kilometres east into Alberta, although it doesn’t say how high those concentrations might be.
The results should encourage more research on the health and environmental impact of those chemicals, Holland said.
“PACs are not just affecting the environment. They’re affecting communities … who are constantly being exposed to coal dust. There haven’t been any community-based health monitoring studies in the Elk Valley.”
A co-author of the study, Alison Criscitiello, said the coal dust can impact how quickly snow melts — which could cause the ground to dry out quicker.
“Cleaner, brighter snow, of course, reflects and and sticks around longer,” Criscitiello said. “And when you have dust and heavy metals and PACs and these dark-looking particles landing on the snowpack, of course it melts faster.”
While the study looked at the impacts of coal dust from mines in B.C.’s Elk Valley, coal mines in the region have previously been scrutinized for toxic selenium that was being leached into nearby rivers.
The study echoes previous findings led by the same scientist involved in the current research, Colin Cooke at Alberta Environment and Protected Areas. In November, Cooke published research that found coal dust had contaminated an alpine lake that is near coal mines but otherwise unconnected.
The new study comes as Alberta’s energy regulator prepares for hearings on Northback Holdings’ applications for coal exploration at Grassy Mountain in southwest Alberta, near the Elk Valley. The regulator is currently deciding on what level of participation should be granted to interveners, based on how directly and adversely affected they are.
One of those interveners awaiting a decision is the Pekisko Group, made up of local ranchers. They have produced a modelling report that also aligns with the new paper, showing coal mining impacts spread far beyond the mine’s immediate vicinity and well into grazing lands.
Laura Laing, who ranches in the area but isn’t a member of Pekisko, said the increasing body of research suggests the regulator should draw its circle widely.
“The impacts of coal affect all Albertans,” she wrote in an email. “An Australian coal company has no right to say we aren’t impacted by their intentions to explore and develop a coal mine on Grassy Mountain.”
