competition to destroy chemical weapons launched by UK and US

The United Kingdom Defence and Security Accelerator (DASA), part of the Defence Science and Technology Laboratory (Dstl) and UK Ministry of Defence (MOD), has launched the ‘Don’t Blow It!’ competition, the first joint UK-US industry competition run by DASA and funded by the MOD and US Department of Defense (US DOD).

Competitors have been asked to identify innovative concepts or adapt current technologies to access, disable and destroy chemical and biological devices. This includes chemical and biological munitions, improvised explosive devices containing lethal agents or containers of bulk quantities of chemical or biological agents discovered on the battlefield or in other austere and resource-limited environments.

Defence Minister Stuart Andrew said:

Horrific incidents stretching from Salisbury to Syria this year have shown us that chemical weapons are sadly still very much a reality – but a reality that we are determined to deal with. Destroying these deadly weapons is a complicated process and not doing it properly could mean devastating collateral damage. These are challenges that we share with our allies like the US. Competitions like this help us to tackle them head on with some of the best and brightest minds across both our countries.

Although it is over 100 years since the first large-scale use of chemical weapons, the threat from both chemical and biological weapons persists. This has been demonstrated by the recent rise in the use of such deadly weapons on the battlefield and in targeted attacks.

Much progress has been made to destroy state-declared global stockpiles of chemical weapons through very successful large scale destruction programmes, utilising techniques such as incineration, explosive destruction or neutralisation. However, to meet emerging and future challenges, such as the destruction of smaller caches produced by terrorists in resource-limited or hostile environments such as Iraq or Syria, there needs to be a focus on developing more robust elimination capabilities that are less labour intensive.

The competition has an initial £500,000 to fund multiple proof-of-concept proposals at low Technology Readiness Levels. Additional funding of £1.5 million is anticipated to be available for future phases.

The competition is seeking innovative ideas from non-traditional supply sectors and is looking for ‘outside-the-box’ proposals that will:

  • enable rapid and flexible destruction
  • reduce logistical support requirements
  • maximise ease of operation and transportability
  • address a greater breadth of threats

MOD Chief Scientific Advisor, Dr Simon Cholerton said:

As the use of chemical weapons in Syria and the Novichok attack in Salisbury demonstrate, the risk from chemical weapons still remains and the issue of safely eliminating them from an austere tactical environment remains an enduring technical challenge. I am delighted therefore that we are working with our closest ally to launch a new industry competition to help us develop effective and safe elimination capabilities. Our collaboration is the first time we have launched a truly joint UK-US competition through the UK Ministry of Defence’s Defence and Security Accelerator, which is charged with enabling us to innovate by rapidly transforming the ideas of today into the capabilities of tomorrow.

Assistant Secretary of Defense for Nuclear, Chemical and Biological Defense Programs, US DOD, The Hon. Guy Roberts said:

The expanding proliferation of chemical weapons use, from state and non-state actors, portends the greatest threat of their use on the battlefield since World War I. My responsibility is to ensure our forces are protected from, and can fight through, any such threats. To that end, we must continually innovate our capabilities, and it is especially important to do so in collaboration with those who fight alongside us. This competition does just that. It allows us to jointly invest in research and development with our closest ally as well as seek innovative ideas from a broader set of brilliant minds who I am confident will lead us to creative solutions.

The competition was launched at an event in London on the afternoon of 26 September 2018. Potential suppliers were provided with context on the challenge by both UK and US speakers, as well as information on how to apply to the competition by DASA.

The submission deadline for proposals is 5 pm GMT (midday EST) on 7 November 2018.

Former Contaminated Mine Site in NWT Declared Clean

The Government of Canada recently announced that the former Tundra Gold Mine, located in the Northwest Territories, has been successfully remediated.  The cost of clean-up was $110 million and was paid for by the government.

Tundra Mine was briefly operational in the 1960’s and was used as a dumping ground in the 1980’s.  It’s former owner, Royal Oak Mines went bankrupt in 1999.

Remediation of the site included revegetating soil, sealing mine openings, consolidating and isolating tailings and waste rock, treating petroleum hydrocarbon impacted soils, erecting barriers for erosion control, and removing buildings.  The clean-up project lasted more than a decade.

Though some re-vegetation has begun, the land – around 240 km north-east of Yellowknife – will remain recognizably an old industrial site for decades to come.

Dominic LeBlanc, Canada’s newly installed minister for northern affairs, called Tundra’s remediation “a great example of the hard work of northerners and the importance of partnerships with local Indigenous communities.”  Northern residents represented 76 percent of the project’s suppliers and 61 percent of its employees.  The Minister stated that the restoration will help local Dene and Métis peoples once again use the land for traditional practices.

The Canadian government will continue to oversea that monitoring of the site to ensure it remains stable.  Monitoring, using a combination of on-site equipment and drones, will cost an unspecified further sum each year.

More work to be done remediating the North

According to an article in Cabin Radio, Tundra’s successful clean-up remains a drop in the larger ocean of contaminated sites within the NWT.  Tundra is the 24th site under federal supervision to have reached this stage, a spokesperson for Crown-Indigenous Relations and Northern Affairs Canada said by email to on Cabin Radio.

federal webpage last updated in 2013 suggests Canada is responsible for more than 50 significant contaminated sites in the territory, including those 24.

separate federal website lists 1,634 contaminated sites within the Northwest Territories, where a contaminated site is defined by the Federal Goverment as “one at which substances occur at concentrations (1) above background (normally occurring) levels and pose or are likely to pose an immediate or long term hazard to human health or the environment, or (2) exceeding levels specified in policies and regulations.”

Some entries on the latter list are considered remediated and their files closed. Some are smaller sites not felt worthy of their own, separate clean-up projects.  Several dozen of them, for example, are grouped under one project to clean up the Canol Trail, a World War Two initiative which left contaminated soil, asbestos, and a range of hazardous materials strewn across 355 km of the Sahtu.

In the 2017-18 financial year, public records show federal agencies were obliged to spend money on some 275 separate contaminated sites in the Northwest Territories.  $157,000 was spent assessing a range of those sites, while a little over $103 million was spent on remediation work.

Of that figure, around $23.6 million was spent remediating the Tundra site in that financial year.

Unsurprisingly, Yellowknife’s Giant Mine – considered among the most toxic sites in Canada, harbouring 237,000 tonnes of poisonous arsenic trioxide in underground chambers – was the only site receiving more remediation money.

In the same period Canada spent just over $36 million on Giant, where full remediation work does not even begin until 2020.

Giant, like Tundra, was owned by Royal Oak when the company collapsed and the site became an unwanted federal problem. The full bill for Giant’s clean-up and maintenance – a program of indefinite, certainly decades-long duration – is expected to reach $1 billion in today’s money.

Developer takes Alberta to appeal board over former Edmonton wood treatment plant

As reported by Global News, Cherokee Canada is fighting five enforcement orders imposed by Alberta Environment and Parks (AEP) connected to the former Domtar Wood Treatment Facility located in Edmonton.  AEP has been conducting an investigation on properties associated with the former Wood Treatment Plant. As a result of the investigation, a number of Enforcement Orders were issued to the current owners, Cherokee Canada.

Nearby residents, concerned by off-site migration of wood treatment chemicals, have been kept up-to-date of the results of the AEP investigation and subsequent enforcement actions. Contaminants from a historical wood treatment processing plant continue to exist on property formerly occupied by the Domtar Wood Treatment Plant.  This contamination, which originated prior to 1987, consists of benzene, dioxins and furans, free hydrocarbons, naphthalene, polycylic aromatic hydrocarbons (PAH) mixtures, and pyrene.

AEP stated in a news release that it issued the Enforcement Orders to ensure the responsible parties implement appropriate remedial measures and mitigate the potential risks that have been identified.  The latest Enforcement Orders require that the source of the contamination be controlled and remedial measures be implemented in specific areas of the property.

Results of off-site testing for contamination in early 2018 found that contamination had not migrated off-site and that there are no health concerns in the surface soil of people’s properties. The off-site testing program was conducted by an independent third-party consulting firm under the direction of AEP.

Cherokee Canada, the developer has started turning the site of the old Wood Treatment Plant in northeast Edmonton into a new residential community but the current and ongoing legal proceedings have halted the project.  “It’s been very difficult because it’s effectively frozen our activities for three years now,” said John Dill, Cherokee Canada’s managing partner.  “It’s very expensive to go through this process, ” he added.

Houses have already been built in the neighbourhood but recently, the AEP questioned the safety of the soil.  AEP said third party testing at the site found chemicals dangerous to human health. The enforcement orders require Cherokee to remediate any contamination.

“The core aspect of these orders is to basically remove potentially large amounts of soil from these sites,” said Gilbert Van Nes, general counsel for the Environmental Appeals Board. “Domtar and Cherokee disagree that this is necessary.”

Both Cherokee Canada and Domtar have completed remediation efforts but AEP, through the enforcement orders, are claiming that they didn’t go far enough.

“Our approach was to take the contaminated soil, isolate it in a separate soil berm — again, a common practice in other jurisdictions — and ensure the soil was protected from exposure to other receptors, humans, animal,” Dill said.  “The disagreement is over how we can remediate this site so it’s safe for residential standards so that we can complete our residential development and restore the site that was previously contaminated to productive use.”

Three environmental experts are heading up the independent appeal board.  The board will pass its findings on to the environment minister and Shannon Phillips will make the final decision on whether construction can resume. However, a decision is not expected until December.

British Columbia: Invitation to Participate: Land Remediation Client Survey

The British Columbia Ministry of Environment and Climate Change Strategy is requesting the assistance on B.C. environmental professionals to complete a survey regarding the suite of contaminated site services provided by the Land Remediation Section.  The survey is part of an internal Ministry effort to examine and evaluate the ways in which contaminated sites services are provided in support of administering the Environmental Management Act and Contaminated Sites Regulation, and feedback will inform efforts to improve the client experience in obtaining these services.

The survey takes approximately 10 minutes to complete, allowing for more or less time depending on how many or few contaminated sites services you use. The survey is open for approximately 6 weeks, and will close on September 5, 2018.

Questions regarding the survey can be forwarded to site@gov.bc.ca.

 

New Technology for Mapping DNAPL Contamination

Laser-induced fluorescence (LIF)

As reported in Groundwater Monitoring and Remediation (38(3):28-42), DyeLIF™ is a new version of laser-induced fluorescence (LIF) for high-resolution 3D mapping of NAPLs in the subsurface.   DyeLIF eliminates the requirement that the NAPL contains native fluorophores (such as those that occur in compounds like PAHs) and therefore can be used to detect chlorinated solvents and other nonfluorescing compounds.

NAPLs were previously undetectable with conventional LIF tools. With DyeLIF, an aqueous solution of water and nontoxic hydrophobic dye is continuously injected ahead of the sapphire detection window while the LIF probe is being advanced in the subsurface.  If soil containing NAPL is penetrated, the injected dye solvates into the NAPL within a few milliseconds, creating strong fluorescence that is transmitted via fiber-optic filaments to aboveground optical sensors. This paper describes a detailed field evaluation of the novel DyeLIF technology performed at a contaminated industrial site in Lowell, Mass., where chlorinated solvent DNAPL persists below the water table in sandy sediments..

The DyeLIF system was field tested at a Formerly Used Defense (FUD) facility in Massachusetts in Fall 2013 (Geoprobe® delivery) and again in March 2014 (CPT delivery). The primary field demonstration completed in 2013 included two components: one week of DyeLIF probing and a second week of follow-on soil coring using research-quality direct push (DP) soil coring methods in order to compare DyeLIF results to colorimetric dye shake tests and laboratory analysis.

Several performance objectives were established in the project demonstration work plan and all were met or exceeded. The performance objective for chemical analysis was 70% consistency between positive DyeLIF responses and samples when DNAPL saturations were greater than 5%. The demonstration results showed 100% consistency between chemical analysis and DyeLIF for saturations greater than 1.9% (35 of 35 samples), and 95% consistency for estimated saturations greater than 0.5% (40 of 42 samples).

ESTCP funded Project ER-201121 to demonstrate the DyeLIF technology.  Additional details on the technology can be found at the U.S. Department of Defence Strategic Environmental Research and Development Program (SERDP) and the U.S. Department of Defence Environmental Security Technology Certification Program (ESTCP) link at SERDP-ESTCP.

Environmental Consultant’s Disclaimer of Liability to Vendor effective against Third Party Purchaser

by Stanley D. Berger, Fogler Rubinoff

On July 23, 2018 the Court of Appeal for Newfoundland and Labrador in the case of Community Mental Health Initiative Inc. v. Summit Lounge Ltd. 2018 NLCA 42 upheld summary judgment dismissing a purchaser’s claim against two engineering companies (consultants) alleging negligence in the conduct of a Phase 1 Environmental Site Assessment performed for the vendor. The agreement between the consultants and the vendor and the final report both indicated that the assessment was prepared solely for the benefit of the vendor and that the consultants accepted no responsibility for any damages suffered by any third party. Significantly, the plaintiff-purchaser had knowledge of the disclaimer, having been provided with a copy of the final report by its real estate agent prior to the closing of the transaction. The Court of Appeal referred to the Supreme Court of Canada’s decision in Edgeworth Construction ltd. v. N.D. Lea & Associates Ltd. [1993] 3.S.C.R. 206 as well as decisions from appeal courts in Ontario Wolverine Tube (Canada) Inc. (1995) , 26 O.R. (3d) 577 and B.C., Kokanee Mortgage M.I.C. Ltd. 2018 BCCA 151 and summarized the legal principles as follows: (at par. 23) “… an express disclaimer of liability can be an effective bar against a claim by a third party who relied on work in the knowledge of the disclaimer. Permitting third parties to rely on reports which are expressly protected by a disclaimer would undermine the ability of contracting commercial parties to govern their own affairs.”

IMPLICATIONS FOR REAL ESTATE TRANSACTIONS AND ENVIRONMENTAL CONSULTANTS?

The long established principle of privity of contract i.e. that the rights and obligations in a contract apply only to the parties to the contract have been further tested by this decision. For engineering consultants, the decision highlights the importance of exacting express disclaimer clauses restricting responsibility for the reporting information to the party retaining them. For purchasers of real estate, it reinforces the necessity of obtaining indemnities from the vendor for undiscovered contamination or if that is not realistic, retaining an independent environmental consultant to verify any consulting reports given to them by the vendor.

Nova Scotia Homeowner Fined for not Investigating Leaking UST

The Nova Scotia Department of the Environment recently fined a homeowner in Sydney (located on Cape Breton Island) with failing to obtain the services of a site professional to determine whether a leaking oil tank had caused contamination.

The regulator had issued two directives to the homeowner prior to filing the charge in court.  The amount of the fine was $350.  The homeowner has been given two years to complete any necessary remediation on his property.

The Nova Scotia Department of the Environment Homeowner Guide to Heating Oil and Tank Systems provides information on how homeowners can lessen the environmental risk posed by above-ground heating oil tanks.  The Province also has a Domestic Fuel Oil Spill Policy.

Unsafe Levels of Contamination found in Edmonton Neighbourhood

As reported in the Edmonton Journal, unsafe levels of hazardous chemicals were found in unoccupied land near the property that was previously occupied by a wood treatment plant site.  However, the analytical results from soil samples taken from residential properties in the vicinity of the plant found no hazardous chemicals in the top level of soil.

An Alberta Health official recently stated that soil testing has been completed in the Verte-Homesteader community — located near the former Domtar wood treatment facility.

“The results show no issues in the surface soil of any of the homeowners’ properties, but there were four areas of unoccupied land in the southeast corner of the neighbourhood where chemicals were found above health guidelines and that area is now being fenced off,” spokesman Cam Traynor said in an email.

A map showed two tests in the soon-to-be-fenced area exceeded human health guidelines for dioxins and furans.

In the spring, about 140 homeowners near the site of the former wood treatment plant at 44 Street and Yellowhead Trail were warned soil and groundwater in the area was contaminated with a list of potentially cancer-causing substances.

Officials said no contaminants were known to be in residential areas.

From 1924 to 1987, the land was the site of a plant in which toxic chemicals were used to treat railroad ties, poles, posts and lumber. Parts of the property are now a housing development.

The site’s current owners and developers, 1510837 Alberta Ltd. and Cherokee Canada Inc., were ordered to build a fence around the contaminated land to reduce potential health risks earlier this year.  Cherokee Canada did not immediately respond to a request from the Edmonton Journal.

Alberta Environment and Parks also directed the companies, including former owner Domtar, to take environmental samples and create plans to remove contaminants and conduct human health risk assessments. The orders also affected a greenbelt southeast of the site currently owned by the City of Edmonton.

The recently completed testing covered the top one-third of a metre of soil. Traynor said deeper soil testing in the broader area is ongoing. That work, along with a human health risk assessment, is expected to be completed this fall.

The National Brownfield Summit – A Brief Recap

By David Nguyen – Staff Writer

This year’s conference is about charting the future of the CBN. (Image from CBN).

On June 13, 2018, The Canadian Brownfields Network (CBN) held their 8th annual conference, taking the form of a National Brownfield Summit. This year also marks the 15th anniversary of the 2003 National Roundtable on the Environment and the Economy report, and the cornerstone of this year’s summit was to revisit the original report and reflect on the progress since then, as well as the challenges that still need to be addressed.

Keynote Speaker

After an introduction by president Grant Walsom, the conference began with the keynote speaker Marlene Coffey, Executive Director of the Ontario Non-Profit Housing Association, who spoke about previous examples of the developments on Brownfields, including housing developed on a Goodyear Tires site, or the Vancouver Olympic village or Toronto Pan American housing facilities.

She spoke of Toronto’s current housing crisis and how costs have outpaced income for many renters due to the market response to the economic growth in the Greater Toronto Area, as well as Hamilton and Waterloo. She also spoke about how condominium development is preferred due to the pre-selling and reselling markets providing profit and equity for the developer before and during construction.  Contrast that to rental housing, where developers of must put up front all costs of development before any profits.

The city of Toronto’s plan to address these concerns include building 69 000 affordable rental units within 10 years, extending the life of 260 000 units, as well as income support for 311 000 households. In addition, the federal government launched the National Housing Strategy in 2017, with $40 billion over 10 years to support affordable housing initiatives across Canada. Coffey reports that municipality participation is key to obtaining funding for affordable housing, and a role that can be played is to donate available land for development.

Current Affairs

A series of professional presentations followed, discussing various emerging investigation and remediation techniques. These included Dr. Barbara A. Zeeb discussing the use of phytotechnologies to remediate brownfield sites. She compared the traditional method of soil excavation, transport, and disposal to phytoextraction – the use of plants to remove the contaminant while leaving the soil intact and reusable, such as using natural and native species to remove organics like DDT. Other benefits include its cost effectiveness and the uptake of greenhouse gasses, but technologies are site specific, and can take years to remediate fully – highlighting the role that phytoremediation can play alongside traditional remediation methods.

A legal update with lawyer John Georgakopoulos provided an overview of legal cases currently before the courts, with implications for the brownfield development. His presentation compared cases of regulatory liability to civil liability and about managing environmental liabilities through exercising due diligence. He noted, however, that due diligence plays a bigger role in regulatory liability and a smaller role in civil liability, and he encouraged environmental liability protections like environmental insurance and regulatory liability protection.

A cross-country checkup with panelists from across Canada discussed the changing landscape for excess soils. Speakers include Krista Barfoot (of Jacobs Engineering Group) speaking about Ontario’s proposed guidelines on excess soils, such as the emphasis on the use of excess soil management plans and addressing issues such as situations where there is no beneficial reuse site. Lisa Fairweather spoke about the Alberta’s Remediation Certificate and its impacts on reducing barriers to brownfields development; and Kerri Skelly spoke about British Columbia’s new excess soil regulations and its goals of clarifying rules for businesses moving soil and increasing the opportunity for soil reuse.

Before breaking up into working groups, the final presentations reviewed the current state of brownfield development in Canada. Angus Ross, who chaired the original task force, discussed how the National Strategy succeeded in addressing liability issues, financial funding, and building public awareness of brownfields. A major recommendation was the formation of a national brownfield network, which led to the CBN.

Ryerson PhD student Reanne Ridsdale presented findings on a survey of about 6,500 brownfield remediated sites across Canada, where 80 participants were polled, including environmental consultants, government officials, lawyers and financiers.

Following was a presentation by a Ryerson student planning studio group compared brownfield policies of each province, based on criteria such as clear policies, an accessible brownfield site inventory, and incentives for development. Ontario, Quebec, and British Columbia were considered to be very progressive in their policies towards brownfield development, but improvements could still be made across Canada in terms of standardizing rules and policies and producing developer friendly guidelines for site remediation. Then PhD student Reanne Ridsdale talked about the results of the CBN/Ryerson survey of the brownfield community’s view of progress in the last 15 years. Respondents indicated that the CBN is too eastern focused on central and eastern Canada, with little presence in the Prairies, as well as being too research-focussed and not conducting enough outreach.

Charting the Future

The day was capped off with breakout discussion groups to discuss “challenge questions” and allow attendees to contribute ideas to future CBN activities to advance brownfield developments. Challenge question topics included the roles of the federal, provincial, and municipal governments, the development of a brownfield inventory, innovations in brownfield developments, and the societal impacts of brownfield development on communities. One of the key discussion points was for the CBN to promote a “Put Brownfields First” mentality, particularly within governments. This includes developing a financing model/regime for governments to support brownfield developments, particularly in smaller municipalities, as well as to harmonize rules and guidelines for brownfield development. In addition, the CBN should facilitate the education of brownfields to local communities and involve land owners and developers in the process of implementing brownfield policies.

The National Brownfield Summit provided an amazing opportunity for members and attendees to provide input towards the goals of the CBN.
