U.S. EPA Evaluates Hurricane Harvey impact on U.S. Superfund Sites in Texas

In a September 8th update, the U.S. Environmental Protection Agency (U.S. EPA) and the Texas Commission of Environmental Quality (TCEQ) stated that the two agencies continue to get updates about the status of specific Superfund sites from the parties responsible for ongoing cleanup of the sites.  The TCEQ has completed the assessment of all 17 state Superfund sites in the area affected by Hurricane Harvey.  The two agencies reported that there were no major issues noted.  The TCEQ will continue to monitor sites to ensure no further action is needed in regards to the storm.

The U.S. EPA completed site assessments at all 43 Superfund sites affected by the storm.  Of these sites, two (San Jacinto and U.S. Oil Recovery) require additional assessment efforts.  Assessments of these sites will take several more days to complete.

The San Jacinto Waste Pits site has a temporary armored cap designed to prevent migration of hazardous material.  The U.S. EPA remedial manager is onsite and overseeing the assessment.  Crews continue to survey portions of the cap that are submerged.  There are some areas where rock has been displaced and the liner is exposed.  The potential responsible party has mobilized heavy equipment and is placing rock on different places on the armored cap to repair the defensive surface. The liner is in place and functional so we don’t have any indication that the underlying waste materials have been exposed. If we find a breach in the exposed liner, we direct the responsible party to collect samples to determine if any materials have been released. Also, the EPA has dive teams to survey the cap underwater if needed.

Work to improve conditions after the storm has continued at the U.S. Oil Recovery site to address flood water from the storm.  Nine vacuum truckloads of approximately 45,000 gallons of storm water were removed and shipped offsite for disposal.  No sheen or odor was observed in the overflowing water, and an additional tank is being used to maintain freeboard to keep water on-site.  The U.S. EPA has directed potential responsible parties or has independently started collecting samples at the 43 Superfund sites to further confirm any impacts from the storm.  The total number of Superfund sites increased from 41 to 43 with the addition of Rapides Parish, Louisiana and Waller County, Texas as disaster declared areas.  Sampling efforts of all 43 sites is expected to be completed early next week with sample results will be available soon.

Victoria, B.C. faces Major Bill to Clean up Contaminated Park

As reported in Victoria News, Laurel Point Park is contaminated and the City of Victoria is looking at a potential $5-million bill to clean it up.

The City will spend up to $350,000 to confirm the degree of contamination and create a remediation plan.

The park, located along the David Foster Harbour Pathway next to property owned by Transport Canada, is contaminated with high levels of metal and petroleum hydrocarbons in the soil and groundwater, according to a staff report presented to council last week. Chemical discharges from nearby property likely contaminated the aquatic environment, water and the soil because of area’s industrial past, the report stated.

For now, there is little risk to the public.  Counsellor Chris Coleman said the contamination is capped and secured, as long as it is left alone.

“If there was (a risk to the public), then we would close the park,” he said.

“It’s the sort of thing that we’ve seen in the past, when there was leeching from the Hartland Road landfill,” Coleman added. “It went into the groundwater … it then caused an algal bloom in the Butchart Gardens. That’s what you’re trying to control for here.”

The park, and the surrounding lands on the Laurel Point peninsula, were burial grounds for the Songhees people prior to 1885, after which it was used by various industrial facilities, including paint factories, machine shops, and for processing coal and oil.

Victoria council approved the next stage of SLR Consulting’s environmental investigation using money from the environmental remediation funds in city’s financial plan for 2017.

The next step in the process is a risk assessment, with an estimated cost of up to $150,000. It will take an additional $50,000 for the remediation plan, and up to $5 million to put the plan into action.

The surrounding land owned by Transport Canada will also have to be excavated and disposed off-site, according to preliminary reports.

Tribunal gives Ontario Environment Ministry Broad Preventative Powers over Migrating Contamination

by Stanley D. Berger

On September 1, 2017, the Ontario Environmental Review Tribunal in the matter of Hamilton Beach Brands Canada Inc. et al. v. the Director, Ministry of the Environment and Climate Change made a preliminary ruling that the Director had jurisdiction to make an order under s.18 of the Environmental Protection Act (EPA) requiring a person who owns or owned, or has or had management or control of a contaminated undertaking or property to delineate contamination that had already migrated to off-site properties. The property in question, formerly a small-appliance manufacturing business, was contaminated and the various contaminants were of concern to the Ministry, having migrated to other Picton residential, commercial and institutional properties where they might be entering nearby buildings by vapour intrusion. Section 18 of the EPA provides that the Director may make orders preventing, decreasing or eliminating an adverse effect that may result from the discharge of a contaminant from the undertaking or the presence or discharge of a contaminant in, on or under the property. The Director’s Order was challenged on three grounds:

  1. The adverse effect the Director could address was limited to a future event or circumstance (given that s.18 is prospective and preventative);
  2. The adverse effect had to relate to the potential off-site migration of a contaminant that was on an orderee’s property at the time the order was made;
  3. The order could require work only on site but not off-site, to address the risk of an adverse effect.

The Tribunal rejected all three arguments, reasoning that adverse effects resulting from contamination were frequently ongoing rather than static, with no clear line between existing and future effects. The Tribunal looked to the purpose of the EPA which was to protect and conserve the natural environment and found the orderees’ arguments were inconsistent with this purpose. Contamination and adverse effects were not constrained by property boundaries and therefore it was immaterial whether the contaminant was on the orderee’s property at the time the order was made. Finally, the list of requirements that could be ordered under s.18(1) EPA included off-site work. _________________

Validation of handheld X-Ray Fluorescence for In-Situ Measurement of Mercury in Soils

Researchers recently reported the results of an evaluation of a handheld X-ray fluorescence (XRF) device as a field screening tool for soil mercury as part of on-going remedial investigations along the South River in Waynesboro, Virginia.  As reported by the research team, the method achieved a detection limit of 7.4 mg/kg Hg with a 60-s analysis time, which improves upon earlier attempts and is sufficient for detecting mercury at generic risk assessment soil screening levels (23 mg/kg Hg).  The study also demonstrated levels of accuracy and precision for the method that rivaled traditional laboratory methods.  In a split-sample comparison with laboratory Method 7471A, field XRF results agreed with an R2 of 0.93 and a median coefficient of variation of 15%.  Precision estimates from duplicate and triplicate samples were not statistically different between the two methods and were constrained by sample heterogeneity rather than by method capabilities.

The study demonstrated that handheld XRF can be successfully used at contaminated sites to achieve high quality Hg results that are accurate, precise, and at a level of sensitivity commensurate with generic risk assessment screening levels.

Arcadis achieves U.S. Department of Defense Accreditation

Arcadis, a design and consultancy firm for natural and built assets, recently announced that it achieved U.S. Department of Defense (DoD) accreditation for its Advanced Geophysical Classification (AGC) quality and technical platforms, enabling Arcadis to identify, test and remove explosive hazards at defense sites and avoid costly excavation of non-explosive debris.

Arcadis was accredited by the American Association for Laboratory Accreditation (A2LA) to perform AGC under the DoD AGC Program to perform complex subsurface munitions identification work.  Accreditation is based on the internationally recognized ISO/IEC 17025 standard and is achieved through a multi-step process including the review, assessment and on-site audit of the Arcadis Quality Management System and demonstration of ability to classify subsurface metallic objects as munitions at a DoD test site.

AGC is an innovative approach to munitions response remediation activities because it classifies subsurface objects as unexploded ordnance potentially containing explosive hazards or non-hazardous materials that can be left in the ground.  Using AGC significantly reduces the number of subsurface objects requiring intrusive investigation and reduces remediation completion costs. The DoD anticipates AGC will significantly reduce their environmental liability by millions of dollars and will accelerate the cleanup of defense sites.

AGC has been successfully used at sites across the U.S. for the DoD Environmental Securities Technology Certification Program, the U.S. Army Corps of Engineers and the U.S. Navy, including a contract with the U.S. Army Engineering and Support Center Huntsville to locate and safely remove World War II-era military ordnance from residential and recreational areas at Fort Pierce, Florida.

Labrador Dump to be converted to Wetland

As reported by the CBC, The Canadian Department of National Defence is cleaning up an old dump in Happy Valley-Goose Bay, Newfoundland and Labrador.

Crews are working to clean up the old dump used by the 5 Wing Goose Bay base, and will be creating an engineered wetland to filter out potential contaminants in the soil.

Happy Valley-Goose Bay is a town of 8,000 people in the located in in the central part of Labrador on the coast of Lake Melville and the Grand River, near the North Atlantic Ocean.

This kind of wetland differs from others that focus on preserving at-risk species of ducks and waterfowl, says Lori Whalen, contaminated sites manager with the Department of National Defence.

“An engineered wetland is a passive designed wetland that is meant to be part of a remedial system, so it’s actually acting like a filter,” she said.

The site was used as the main dump for 5 Wing Goose Bay, and Whalen said the pollution is mainly a legacy of the American Air Force when they used the base in the mid- to late 1900s.

At that time, Whalen said, there were not environmental regulations in place to ensure things were disposed of properly.

“We have material from domestic waste, construction debris, barrels that would have contained fuels and lubricating materials, even vehicles … that were just thrown over the bank,” Whalen said.

The Goose Bay Remediation Program has a $13.5-million cost and is part of a larger federal government program to clean up contaminated sites around Canada.

A majority of the work will be done this summer, National Defence said, and while it continues, people are being asked to steer clear of the site.

Whalen said this project should help ease concerns in the community over the years that pollution from the base could be affecting the water.

“The extensive sampling programs that we’ve done over the past 20 years points out that drinking water is safe for consumption,” Whalen said.

“The surface water that’s flowing through the culverts off site is below the appropriate criteria and we haven’t seen any issues in the ground water as well.”

Meanwhile, people in the community like John Hickey, who has been pushing for the base’s cleanup since he was mayor in the early 2000s, said there’s plenty more to be done.

“When it comes to the environment, we’ll never be satisfied,” said Hickey, who was also an MHA for the area.

“We have to ensure now that, while this work is being done, other work that needs to be done is identified and is cleaned up.”

But Hickey said he is happy to see this site getting the attention it deserves.

“This is going to be, I think, a very nice place when it’s finished and completed,” Hickey said.

“I think you’ll see a lot of waterfowl and things moving in to the area, which is all good for our community.”

CN sued by Mattagami First Nation over oil spills

As reported in Timmins Today, the Mattagami First Nation, a northern Ontario Indigenous community, is suing CN Rail for alleged environmental and cultural damage caused by two 2015 derailments that led to significant oil spills.

The Mattagami First Nation alleges in its statement of claim that the spills near Gogama, Ont., damaged the local environment and surrounding waterways.

The $30 million suit alleges that the damage, in turn, has created health risks for the population and crippled community members’ ability to observe their Indigenous traditions including fishing, hunting and gathering.

It says the two oil spills, which took place in February and March 2015, collectively poured millions of litres of oil into the area around Gogama, which is about 200 kilometres north of Sudbury, Ont.

CN declined to comment on the filing, adding it is committed to cleaning up environmental damage caused by the derailments.

Mattagami’s allegations have not been proven in court.

The First Nation claimed the 2015 spills impacted many facets of life for community members.

“Mattagami First Nation members have suffered stress, distress, anxiety and worry as a result of the contamination of the land, waters, plants and animals on which they rely,” reads the First Nation’s statement of claim, which was filed in March but served to CN on Monday.

The suit alleges negligence from CN and claims the rail company breached its standard of care when conducting operations ranging from track maintenance to staff training. It also alleges CN has created a corporate culture that valued speed over safety.

Canadian Government will clean up Iqaluit dumpsite

As reported in Nunatsiaq Online, an old Iqaluit dumpsite littered with metal refuse, fuel barrels and other toxic waste overlooking the Sylvia Grinnell River will soon be removed, following a multi-million dollar remediation contract recently issued by the federal government.  Iqaluit is the capital city of the Canadian territory of Nunavut.  It sits on vast Baffin Island in Frobisher Bay, in Canada’s far north.

Transport Canada has confirmed that it awarded over $5.4 million to Kudlik Construction Ltd. for cleanup of the dump,which lies along the mouth of Sylvia Grinnell River—a popular source of fish.

The contract follows recommendations outlined in a 2016 report by Arcadis Canada Inc., commissioned by Transport Canada, that detected the hazardous debris buried in the area and noted in earlier studies dating to 2001.

“The nature of the debris in the main landfill and scrap metal dump suggest that the [United States Air Force] was likely responsible for depositing a large portion of the wastes currently found on the site,” said the report, which estimated the dump was started around 1963.

That’s when the Frobisher Bay airbase and weather station was sold to Canada by the U.S. military, but not before American personnel bulldozed old cars, appliances, fuel containers and other toxic refuse over a cliff near the river, the report said.

The site was used intermittently until the 1970s, when it was abandoned for another landfill near Apex.

The area is still used today as a “rogue dumping site” by local residents, the study said, and that could be another source of contaminants. Along with the remains of vintage army vehicles and cars, appliances and modern waste, like car batteries.

Surveyors identified toxic petroleum hydrocarbons, polychlorinated biphenyls, or PCBs, pesticides, and other hazardous materials at four zones within the dumpsite, extending from higher ground to within a few metres of the river.

Work will begin at the site in the coming weeks and will continue until October, Transport Canada said. The remaining non-toxic waste will be sealed into a new landfill and monitored closely until 2020.

“It’s great news that the Sylvia Grinnell area is being remediated,” Iqaluit Mayor Madeleine Redfern told Nunatsiaq News July 25. But she said other old dump sites grounds surrounding the city remain unaddressed despite concerning signs of contamination.

The question is: who is responsible for cleaning them up?

Since many of the contaminated sites predate Iqaluit’s incorporation as a municipality, the responsibility for their remediation—such as the old metal dump—can be hotly contested.

Transport Canada said its responsibilities to remediate land in Iqaluit extend to areas like the Sylvia Grinnell dump, as part of an agreement to cleanup lands around the airfield that were transferred to the Government of Nunavut in the 1990s.

But in submissions to the Nunavut Planning Commission for its upcoming draft Nunavut Land Use Plan, the City of Iqaluit identified eight contaminated sites in and around the municipality that don’t fall under the airfield agreement.

Those include areas that have yet to be remediated in West 40, Federal Road, Apex, Upper Base and Lower Base.

Redfern said various reports on contamination around Iqaluit often never find their way to the right departments, leading to confusion or inaction between municipal, territorial and federal governments on the implementation of their recommendations.

And costs associated with remediation fall well outside the financial abilities of Nunavut municipalities.

“The local level governments have never had the money to effectively be able to handle environmental remediation within their communities,” Redfern said, adding that in her two terms as mayor she’s approached federal and territorial governments about “half a dozen times” on the issue.

“Many of the residents have wondered how these sites get prioritized and the city and the residents would greatly appreciate seeing all these historical sites remediated.”

A report commissioned in 1995 at the site of the old Apex dump found elevated—but below hazardous—levels of lead, copper, zinc and PCBs in nearby soil and marine sediment on the nearby shoreline.

Redfern said the possibility of leaking contaminants from the dump could effect the quality of clams in the bay, but governments not addressed the issue.

“What is the status of the Apex dump, is it still leaching, was remediation ever done?” she asked. “If it is leaching toxins then notices should be put up around the area.”

And the city’s closed North 40 metal dump—northwest of downtown Iqaluit—also dates to the era of the U.S. air base, and shows signs the site may be leaking.

Another study by researchers from the University of Saskatchewan published in 2010 noted elevated levels of hydrocarbons in Iqaluit’s Lower Base area, but concluded the levels are too low to be of risk to human health.

Lower Base used to be a dumping ground for spent fuel canisters, dating back to the earliest period of the U.S. air base in the 1940s.

Redfern added that a study estimated costs to remediate toxins discovered in the last of of the old Butler buildings in Lower Base, one of the oldest structures in Iqaluit, at more than $1 million.

Modern Iqaluit, or Frobisher Bay, was founded when the U.S. military constructed the Iqaluit airfield during World War II, as a rest point for planes flying to Europe on the Crimson Route.

During the Cold War, Frobisher Bay became a central relay point for construction of DEW line stations across Canada’s North, which were built to detect bombers from the Soviet Union crossing into North America through the Arctic.

After the DEW line was replaced by the North Warning System, starting in the late 1980s, many of those stations were abandoned in the early 1990s, leaving behind heaps of toxic waste and contaminants.

In 1996, the Department of National Defence began remediation of 21 DEW line sites across the Arctic at a cost estimated at over $575 million in 2014.

Despite being surrounded by many of the same hydrocarbon and PCB contamination garbage leftover from military uses, only a few hazardous sites near Iqaluit—like Upper Base and Resolution Island—were marked for cleanup as part of that project.

“While remediation [of Resolution Island] provided benefits to the community of Iqaluit, primarily through contracts and employment, the community of Iqaluit has not received the same level of special designation or status for remediation clean up,” the City of Iqaluit said in its submissions to the Draft Nunavut Land Use Plan.

“Despite the fact the Americans set up [Iqaluit] and used key areas within the community for military purposes.”
