Nova Scotia announces plan to remediate two abandoned gold mines

The Nova Scotia provincial government recently announced it plans on spending $47.9 million (Cdn.) to clean up two former gold mines in the province.  The two mines – Goldenville, near Sherbrooke on the Eastern Shore, and Montague Gold Mines, in Dartmouth – are deemed to be the most contaminated of dozens of abandoned sites in Nova Scotia.

Analysis

The two sites were mined extensively from the 1860s to the early 1940s. Back then, environmental regulations were non-existent, or, at best, inadequate.  Miners used liquid mercury to extract gold from crushed rock, and the mine tailings were disposed in nearby waterways.  Arsenic, which occurs naturally in rock, was also released as part of the mining process.

Analysis of samples from the two abandoned mines site reveal that levels up to 200,000 mg/kg at the Goldenville mine and 41,000 mg/kg at the Montague mine.  The Nova Scotia Environment Department’s human health soil quality guideline is 31 mg/kg.

Remediation Plan

With respect to inorganic mercury, samples from the two mine sites were found to be at levels reaching 48 mg/kg at Goldenville and 8.4 mg/kg at Montague.  The Canadian Council of Ministers of the Environment’s human health and ecological soil quality guidelines for inorganic mercury is 6.6mg/kg.

The remediation plans involve excavating the tailings with the greatest contamination to a depth of two metres and placing them in a lined containment cell.  The cells will than be capped so water cannot enter them and clean backfill will be added on top.

At Montague, two containment cells will each be 95 metres by 95 metres and five metres high, made with a berm, an impermeable liner, a leachate collection system and an impermeable cover system. At Goldenville, the same structures will be built, but one will be 180 metres by 180 metres and the other will by 135 metres by 135 metres.

The two sites will also require a water treatment system as well as a wall to prevent contaminated water from leaving the excavation zone.

In other areas with lower levels of contamination, a protective, low-permeability cover will be placed on top of the tailings to prevent precipitation from getting into the contaminated soils. That barrier will then be covered with soil and vegetation.

Company fined $564,000 for violating VOC limits in CEPA Regulations

An automotive parts supplier based in Quebec, Les Entrepôts A.B. inc., was recently fined a total of $564,000 after pleading guilty, on October 4, to three counts of contravening the Canadian Environmental Protection Act, 1999 and the Volatile Organic Compound (VOC) Concentration Limits for Automotive Refinishing Products Regulations, which are part of the Act.

An investigation by Environment and Climate Change Canada (ECCC) enforcement officers revealed that the company had imported, offered for sale, and sold automotive refinishing products that contained volatile organic compounds in excess of the allowable limit. The company also failed to comply with an environmental protection compliance order issued by an enforcement officer, under the Canadian Environmental Protection Act, 1999.

The company received two fines of $125,000 for importing and selling the products, respectively, totaling $250,000, and a fine of $150,000 for failing to comply with an environmental protection compliance order. In addition to the fines on the three counts, the company received an additional $164,000 fine for financial gains. This amount represents the profits generated by the sale of non-compliant automotive refinishing products. The total fines will be directed to the Environmental Damages Fund.

In addition, the judge ordered the confiscation and destruction of the automotive refinishing products seized at the company’s expense, as well as the publication of an article in Le Carrossier magazine (Autosphere.ca) within six months. The article must contain the facts of the offence and the details of the sentence.

As a result of this conviction, the company’s name will be added to the Environmental Offenders Registry.  The Environmental Offenders Registry contains information on convictions of corporations registered for offences committed under certain federal environmental laws.

Volatile organic compounds are primary precursors to the formation of ground-level ozone and particulate matter, the main components of smog. Smog is known to have adverse effects on human health and the environment.

It is estimated that over 5 kilotonnes of VOCs are emitted each year from coatings and surface cleaners used in automotive refinishing operations in Canada. The Volatile Organic Compound (VOC) Concentration Limits for Automotive Refinishing Products Regulations are expected to reduce the annual VOC emissions from these sources by approximately 40%.

The Automotive Refinishing Products Regulations set concentration limits of volatile organic compounds for 14 categories of automotive refinishing products identified in the schedule of the regulations.

The Regulations are aligned with limits set by the California Air Resources Board suggested control measure (CARB SCM) for automotive refinishing products. During regulatory development, it was determined that the greatest potential reduction in Canada would be achieved by establishing VOC concentration limits similar to the CARB SCM. Other jurisdictions in the United States, as well as the European Union, have either already established similar limits or are considering them. Therefore, aligning the Regulations will facilitate consistency across North America, provide a level playing field to manufacturers and importers of automotive refinishing products, and provide consistent treatment across jurisdictions.

 

Quebec Dry Cleaner fined $77,000 for environmental offences

The owner of a Quebec-based dry cleaning company (9042-6560 Québec Inc., operating as Net Escompte-Serge Daoust) in Laval, was recently sentenced in a Quebec court and ordered to pay a penalty of $77,000. He pleaded guilty to four counts of violating the Tetrachloroethylene (Use in Dry Cleaning and Reporting Requirements) Regulations under the Canadian Environmental Protection Act, 1999. He also pleaded guilty to failing to comply with an environmental protection compliance order issued by an enforcement officer under the Canadian Environmental Protection Act, 1999. The entire amount of the fine will be directed to the Government of Canada’s Environmental Damages Fund.

In addition to the fine, the court made an order under subsection 291(1) of the Canadian Environmental Protection Act, 1999. The order stipulates that the owner must:

  • refrain from engaging in any activity that may result in the continuation or repetition of the offence;
  • publish, within six months after the judgment, an article on the facts relating to the offence in Fabricare Canadamagazine and provide proof of publication to Environment and Climate Change Canada;
  • display the magazine article in the window of his business for a period of 12 months following publication;
  • complete Seneca College’s Dry Cleaners Environmental Management Training Course within 18 months after the judgment and provide proof of successful completion to Environment and Climate Change Canada;
  • design and implement training for his employees, develop a safe procedure for using and handling tetrachloroethylene, and provide Environment and Climate Change Canada with a copy of the procedure as well as the date and names of the employees trained as soon as possible; and
  • within two months after the judgment, bring into compliance the dry cleaning machine used in the offences committed under the Tetrachloroethylene (Use in Dry Cleaning and Reporting) Regulations and the Canadian Environmental Protection Act, 1999, unless he decides to dispose of it voluntarily. Environment and Climate Change Canada shall be informed in advance of the persons selected to conduct the inspection and a copy of the inspection report shall be submitted to them. If necessary, corrections shall be made and confirmation sent to the Department.

Tetrachlorethylene, also called PERC, is a solvent whose use is widespread, especially in dry cleaning. The liquid has an ethereal odor, is colorless, volatile and almost non-flammable. It is designated as a toxic substance under the Canadian Environmental Protection Act, 1999 since it can enter the environment through the atmosphere, damage plants and end up in groundwater.

The charges were laid after an inspection of the company’s premises in October 2016, during which Environment and Climate Change Canada enforcement officers found violations of the Tetrachloroethylene (Use in Dry Cleaning and Reporting) Regulations. The offences identified involve the storage and disposal of tetrachloroethylene waste and the maintenance, conservation and production of records in relation to dry cleaning activities. To remedy these offences, a compliance order was issued. However, the owner did not comply with it.

Record $2.7 million fine for company causing oil spill in B.C.

Kirby Offshore Marine Operating LLC was recently sentenced in the Provincial Court of British Columbia, in Bella Bella, after pleading guilty to three charges of violating federal legislation, in connection with an October 13, 2016, spill from the vessel Nathan E. Stewart into Seaforth Channel near Bella Bella, British Columbia.

The company was sentenced to pay the following penalties:

  • $2.7 million for the offence of depositing a deleterious substance into water frequented by fish, in violation of the Fisheries Act;
  • $200,000 for the offence of depositing a substance harmful to migratory birds, in violation of the Migratory Birds Convention Act1994; and
  • $5,000 for the offence of failing to comply with the pilotage requirements under the Pilotage Act.

The $2.7 million penalty imposed under the Fisheries Act is the largest fine for the deposit of a deleterious substance into water frequented by fish from a single spill. This penalty will be directed to the Government of Canada’s Environmental Damages Fund and is recommended to be used toward the conservation of fish and fish habitat in the Central Coast region of British Columbia. The $200,000 penalty for the offence under the Migratory Birds Convention Act1994 will also be directed to the Fund.

On October 13, 2016, the tug boat Nathan E. Stewart ran aground at Edge Reef near Bella Bella, British Columbia, resulting in the release of approximately 107,552 litres (28,412 gallons) of diesel fuel and 2,240 litres (591 gallons) of lubricants. Both substances are deleterious to fish and migratory birds. Kirby Offshore Marine Operating LLC owned the Nathan E. Stewart.

The articulated tug-barge combo was on its way back to Vancouver from Alaska at the time of the incident. The fuel barge was empty, but the tug quickly began leaking diesel into the water. Seven crew members were on board, but no one was injured.

Husky Oil fined $2.7 million for oil spill into the North Saskatchewan River

Husky Oil Operations Limited recently pleaded guilty to one count of violating the Canadian Fisheries Act and one count of violating the Migratory Birds Convention Act, 1994 in a Saskatchewan court.

The company was ordered to pay a fine of $2.5 million for violating the Fisheries Act and a fine of $200,000 for violating the Migratory Birds Convention Act, 1994. The fines will be directed to the Government of Canada’s Environmental Damages Fund and will be used to support projects within the North Saskatchewan and/or Saskatchewan River and their associated watersheds related to the conservation and protection of fish and migratory birds.  

The charges related to an incident that occurred between July 20 and 21, 2016, when an estimated 225,000 litres of blended heavy crude oil leaked from a Husky Oil Operations Limited pipeline. Approximately 90,000 litres of the oil entered the North Saskatchewan River near Maidstone, Saskatchewan. The oil was found to be deleterious, or harmful, to fish and migratory birds.   

Environment and Climate Change Canada’s National Environmental Emergencies Centre (NEEC) responded to the July 2016 spill. Environmental emergency officers were onsite from July 22, 2016 until early October 2016 to provide regulatory oversight and guide efforts to protect the environment. A year after the spill, in 2017, and once again in 2018, NEEC’s Shoreline Cleanup Assessment Team returned to the North Saskatchewan River to assess the water and shorelines following the spring ice breakup.

Clean-up Activities of the North Saskatchewan River

The spill resulted in a number of communities having to stop taking water from the North Saskatchewan River for drinking water purposes. The cities had to shut off their intakes and find alternate water sources after the oil plume from a Husky Energy pipeline spill moved downstream. The cities of North Battleford, Prince Albert, and Melfort were ordered by Saskatchewan’s Water Security Agency to stop taking water from the river.

In addition to pleading guilty to offences under federal legislation, Husky Oil Operations Limited has pleaded guilty to one count under the provincial Environmental Management and Protection Act, 2010

UBC fined $1.2 million for Release of Ammonia-laden Water

The University of British Columbia and CIMCO Refrigeration were recently sentenced for offences committed in violation of the Canadian Fisheries Act, related to a 2014 ammonia-laden water release that ended up in a tributary of the Fraser River.

CIMCO Refrigeration was fined $800,000 after pleading guilty to depositing or permitting the deposit of a deleterious substance into an area that may enter water frequented by fish.

The University of British Columbia was fined $1.2 million after being found guilty of the several offences including the depositing or permitting the deposit of a deleterious substance into water frequented by fish (Booming Ground Creek) and failing to report the incident in a timely manner.

In addition to the fine, the University was also ordered to conduct five years of electronic monitoring of storm-water quality at the outfall where the release occurred.

The University has filed an appeal against these convictions.

Background on the Incident

On September 12, 2014, Environment and Climate Change Canada was contacted regarding an ammonia odour at an outfall ditch connected to Booming Ground Creek in Pacific Spirit Regional Park. The source of ammonia was identified as coming from a refrigeration plant at Thunderbird Arena at the University of British Columbia.

CIMCO Refrigeration and the University were completing repairs of the refrigeration system and used a negative pressure device, known as a Venturi, to purge residual ammonia vapours from the system. The mixture of water and ammonia was then discharged into a storm drain at the arena, which flowed to the outfall, through a ditch, and into Booming Ground Creek, which is a tributary of the Fraser River.

Officers and park rangers found approximately 70 dead fish in Booming Ground Creek in the two days following the discharge. The level of ammonia deposited in the water in the storm drain and ditch was analyzed and found to be harmful to fish.

As a result of this conviction, both organizations’ names will be added to the Environmental Offender’s Registry.

Solvent Spill from Transport Truck results in $100,000 fine

Penner International Inc., headquartered in Manitoba, was recently convicted on one charge on the Ontario Environmental Protection Act as a result of a spill of solvent from one its transport trucks in 2017. The company was fined $100,000 plus a victim surcharge of $25,000.

The driver of the vehicle involved in the solvent spill was also personally charged and convicted. He was fined $35,000 plus a victim surcharge of $8,750. He was given 12 months to pay the fine.

In spill occurred on July 20, 2017 in the Town of Gwillimbury, approximately a 1-hour drive of Toronto. A Penner tractor-trailer driven a by independent contractor was heading north on Highway 400 when it rear-ended a pick-up truck that swerved in front of it, ultimately leading to a spill of solvent VORTEX WPM onto the highway.

The VORTEX PM had been picked up by the driver earlier in the day from a Mississauga, Ontario distribution company and loaded onto the trailer. The load consisted of twelve stainless steel 1500-kilogram. The distribution company did not secure them to the trailer.  The driver did not inquire as to whether the totes were secured or not before he closed the doors to the trailer and drove off.

During transport and at the time of the rear-ending incident, as the totes were not properly secured, they shifted and the valves on two of the totes were knocked open. Solvent spilled from the trailer onto the highway and some also ran down gradient onto the soil of an adjacent construction site.

A one-kilometre evacuation zone was also established around the spill site. The closure remained in force for 10.5 hours, and the construction site’s operations were affected for a few days.

Hundreds of motorists were trapped on Highway 400, where the spill occurred, for up to five hours before they could be re-routed to ancillary roads.

VORTEX WPM is an organic solvent that is flammable. To clean up a large spill of VORTEC WPM, the Material Safety Data Sheet (MSDS) for VORTEX WPM states: “Eliminate all ignition sources. Persons not wearing protective equipment should be excluded from area of spill until clean up has been completed. Stop spill at source. Prevent from entering drains, sewers, streams, etc. If runoff occurs, notify authorities as required. Pump or vacuum transfer spilled product to clean containers for recovery. Transfer contaminated absorbent, soil and other materials to containers for disposal.”

Penner International Ltd. was founded in 1923 and specialized in truckload dry van, international, and Canadian transport.
