Tracking brownfield redevelopment outcomes using Ontario’s RSCs

By David Nguyen, staff writer, Hazmat Management Magazine

GeoEnviroPro’s latest webinar event featured Dr. Christopher De Sousa, a professor and director of the School of Urban and Regional Planning at Ryerson University.  He spoke about his research using record of site conditions (RSCs) to track brownfield developments in Ontario.

Christopher De Sousa.BA, MScPL, PhD (Associate Professor, Ryerson University)

A RSC is typically filed on the Environmental Site Registry with the Ontario Ministry of the Environment and Climate Change (MOECC) after property has undergone a Phase I, and often a Phase II Environmental Site Assessment (ESA) and the property is undergoing a zoning change to a more sensitive land use (i.e., industrial to residential).  A record of site condition summarizes the environmental condition of a property, based on the completion of ESAs.

De Sousa’s research focussed on the effects of the RCS legislation since its introduction in 2004, focussing on the scale and value of projects using RSCs from 2004 to 2015 (noting the revisions to the RSC legislation in 2011).  Property Assessments and Tax information was used to determine the nature of the developments that have occurred on brownfields.  Private sector stakeholders were interviewed to determine the factors that influence private sectors to develop on brownfields.

The research showed that from 2004 – 2015, 31% of RSCs were filed for Toronto properties.  However, the cities with the greatest total area redeveloped (based on RSC filings) were Brampton and Vaughn, with Toronto having the third largest total area redeveloped. With the exception of Ottawa, projects requiring RSCs occurred primarily in the greater Toronto and Hamilton area.

Of the RSCs filed from 2004 – 2015, 24% consisted of only Phase I environmental site assessments (ESA), 69% consisted of a generic Phase I and II ESAs, and 7% used a Phase I and II ESA combined with a site specific risk assessment.

With land use changes, the most common previous land use was commercial (36.8%) followed by industrial (22.3%) and the most common intended land use was residential (67.5%) followed by commercial (14.9%).

Toronto’s development focussed on residential projects located near major transit and roadways (85.6% of which being condos).  Smaller municipalities like Waterloo and Kingston also primarily developed residential properties (31% and 58%, respectively).  De Sousa notes that provincial growth plans and community improvement plans can help municipalities be more proactive in housing and economic development goals.

From a private sector perspective, the main motivations for brownfield developments are based on real estate factors (profit, market, locations), with barriers being costs, liabilities, and time (in project reviews and approvals).

Facilitation strategies that governments can utilize involve financial and regulatory changes, particularly in more effective and efficient processes and tools in high priority areas, with perhaps more government intervening regulations in secondary/ weaker markets to encourage development of brownfields vs. greenfields.

Largest Clean-up Grant in Canadian History

As reported by Laura Osman of the CBC, Councillors on Ottawa’s finance committee unanimously approved a $60-million grant to clean up contaminants to make way for a massive new development on Chaudière and Albert islands.

Windmill Development Group applied for the grant for its mixed-use Zibi project.

Windmill will clear the contaminated soil on the site, which has historically been used as an industrial site, and demolish a number of buildings.

“These are contaminated lands on a derelict site in the city’s urban core,” said Lee Ann Snedden, director of Ottawa’s planning services.

“This truly is a poster child for a brownfield grant.

The city’s brownfields redevelopment program awards funds to developers for cleaning up contaminated sites and deteriorating buildings, which helps encourage developers to build in the core rather than the suburbs.

The grant would pay for half of the total projected cost of the cleanup.

Windmill has promised to create a $1.2 billion environmentally friendly community with condos, shops, offices, waterfront parks and pathways on the 15-hectare site, which spans both the Quebec and Ontario sides of the Ottawa River.

The city will only pay for the actual costs of cleanup after the invoices have been verified, Mayor Jim Watson said.

The developer promised to only do the work if they find contamination is present.

“It would be fantastic news for us as the proponent if there’s less contaminants there,” said Jeff Westeinde with Windmill Development Group.

The developer hopes to have the Ottawa part of the development completed in seven or eight years.

Snedden pointed out the city will not  pay to clean up the nearby LeBreton land to allow development because the land is controlled by the federal government.

But the National Capital Commission technically owned about 20 per cent of the Zibi development lands as well said Coun. Catherine McKenney, who argued the federal government should contribute to the cleanup costs.

The NCC owned the lands and had a perpetual lease with Domtar, which operated a paper-mill on the site for nearly 100 years.

“So why are we paying the cost?” asked Peter Stockdale with the Fairlea Community Association.

Some councillors received letters from constituents concerned about the large amount of money going toward a money-making venture.

Capital ward Coun. David Chernushenko acknowledged the grant was “staggeringly” large, but said someone must be responsible for cleaning up contaminated sites.

“I don’t see this as some sort of corporate welfare,” he said.

The grant will still need to be approved by city council.

Examples of Groundwater Remediation at National Priorities List Sites

The U.S. EPA recently issued a report that report highlights a select number of example National Priorities List (NPL) sites where EPA has used innovative and established technologies to restore groundwater for use as a source of drinking water. In these examples groundwater was successfully restored for drinking water use at 17 NPL sites and significant progress toward groundwater restoration was made at an additional 13 NPL sites where contaminants remain above safe drinking water levels. These sites demonstrate how the Superfund program can overcome challenges related to difficult contaminants of concern and complex hydrogeologic settings (May 2018, 114 pages).

The report documents where innovative and established technologies have been used to restore groundwater to beneficial use. This report includes a select number of example National Priorities List (NPL) sites where the remedial action objective (RAO) and associated cleanup levels were to restore groundwater for use as a source of drinking water. Groundwater was restored for use as drinking water at 17 NPL sites and significant progress toward groundwater restoration has been made at an additional 13 NPL sites where contaminants remain above safe drinking water levels in only a few groundwater wells. The RAO of restoring groundwater for beneficial use was achieved under the Superfund program, including the successful treatment of groundwater to federal and state maximum contaminant levels for drinking water. These sites are examples of where the Superfund program overcame difficult remediation challenges, such as groundwater contaminated with chlorinated solvents (including the presence of dense non-aqueous phase liquids [DNAPLs]) and complex hydrogeologic settings.

One of 114 Superfund sites in New Jersey, former Edgewater manufacturing site Quanta Resources has been on the National Priorities List since 2002.

The NPL sites discussed in this report were selected based on several criteria, including the use of innovative cleanup technologies or approaches to remedy concentrated groundwater plumes. The most commonly occurring contaminants of concern at these sites were chlorinated volatile organic compounds, which were present at 26 of the 30 sites. The less frequently occurring contaminants included metals, non-chlorinated volatile organic compounds, semivolatile organic compounds, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons, with dioxins or pesticides only present at one site.

The restoration of groundwater was achieved most often by combining remedial technologies. For example, soil excavation and groundwater extraction and treatment (i.e., pump-and-treat) were used to restore groundwater at 17 of the 30 NPL sites. Given that many of these sites were cleaned up during the period from 1983 to 2000, the remedies used at these sites represented state of the art technologies at that time. These traditional technologies were often modified or replaced with innovative technologies such as in situ bioremediation, in situ chemical oxidation (ISCO), in situ thermal treatment (ISTT) or monitored natural attenuation (MNA) at some sites. The application of remedial technologies at these sites decreased contaminant concentrations from 90% up to 99.99% (i.e., one to more than four orders of magnitude).

DNAPLs were found or suspected at eight of the 30 sites. A combination of excavation and pumpand-treat was used most often to remediate these sites along with at least one other technology or approach such as vertical engineered barrier, air sparging, in situ bioremediation, STT, or MNA. Of the eight DNAPL sites, groundwater was restored for use as drinking water at three sites and significant progress towards restoration has been made at five sites. These findings indicate that the Superfund program has achieved the cleanup of sites with DNAPLs.

The time required to restore groundwater for use as drinking water at the 17 NPL sites ranged from three to 27 years with a median time of eight years. Cleanup time generally increased as the amount of contaminant removed increased with the exception of four sites where contaminant concentrations were decreased by nearly 99.99% in less than eight years. Cleanup times were generally shorter for sites with less complex hydrogeologic settings with the exception of three sites with mild heterogeneity that required more than 15 years to restore groundwater. Also, in most cases, cleanup times were shorter for lesser reductions in concentration.

All of the 30 sites, with the exception of two, have achieved the status of sitewide ready for anticipated reuse (SWRAU), and 12 of these sites have been returned to use either in whole or in part. Reuse includes industrial and commercial redevelopment, recreational use, alternative energy use, and lifting of groundwater use restrictions.

Ontario Legal Report: Thompson Fuels Ordered To Pay Costs

Article by Paula LombardiSiskinds LLP

The case of Gendron v. Thompson Fuels, related to a home furnace oil tank that developed a leak in December 2008. The leak caused damage to the Gendron’s home and the surrounding environment, including nearby Sturgeon Lake. The City of Kawartha Lakes cleaned up the Lake.

On July 17, 2017 the court released its decision on this matter, (2017 ONSC 4009) granting judgement in favour of Gendron against Thompson Fuels. The court appropriated 60% liability to Gendron and 40% to Thompson Fuels. The parties agreed that, based on the court’s findings, Gendron’s total damages were $2,161,570, and Thompson Fuels’ portion of those costs equalled $901,747 ($864,628 plus $37,119 interest). In that decision the court found that the two remaining defendants, the Technical Standards and Safety Authority (“TSSA”) and Les Reservoirs D’Acier De Granby Inc. (“Granby”) were not liable.

The parties were unable to agree on costs and requested that submissions on costs be deferred until the decision on the post-trial motions was released. On March 29, 2018 the Court ordered Thompson Fuels to pay Gendron’s costs on a partial indemnity basis in the amount of $473,000.00 (2018 ONSC 2079). In arriving at this amount, the Court considered the Gendron’s contributory negligence, the costs of various post-trial motions brought by the parties, the reasonableness of Gendron’s bill of costs, and the fact that neither party had beat its offer to settle.

The Court then awarded $150,000 in costs to TSSA as against Gendron and Thompson Fuels, who had cross-claimed against TSSA. The Court further ordered Gendron and Thompson Fuels to contribute $140,000 and $10,000, respectively. The Court also ordered Gendron and Thompson Fuels to pay equal shares of TSSA’s costs of $7,500.00 for the post-trial motions. In deciding to award only partial indemnity costs, the Court found that given TSSA’s limited involvement at trial, it did not require two lawyers to attend at trial. The Court also noted that even though Gendron’s action in negligence against TSSA had failed, the trial Court had found that the TSSA had not been “a model of efficiency or clarity” in its dealings with Gendron.

Despite Efforts to Roll-Back Other Program Requirements, U.S. EPA Administrator Scott Pruitt Continues to Prioritize Superfund Cleanups

by Van P. Hilderbrand, Jr. and Marian C. Hwang

 

 

U.S. Environmental Protection Agency (“EPA”) Administrator Scott Pruitt has made it clear that one of his top priorities during his tenure is to expedite cleanups at contaminated sites across the country. To achieve this goal while facing potential budget cuts, he has made several significant decisions over the last year to overhaul and restructure the Superfund cleanup program from within.

First, as we discussed in our earlier post, A New Budget, a New EPA Administrator, and New Uncertainty for Superfund Cleanups, Administrator Pruitt issued a memorandum on May 9, 2017 centralizing decision-making on major Superfund remedies to EPA headquarters. Specifically, final decisions on remedies exceeding $50 million are to be made by Administrator Pruitt or the Deputy Administrator, not by Regional Administrators. According to the memorandum, this change is designed to improve the remedy selection process by promoting increased oversight and accountability and by “enhancing consistency in remedy selection across states and the regions.”

Next, Administrator Pruitt specially convened an EPA Superfund Task Force on May 22, 2017. In our post, EPA’s Task Force Recommendations to Revamp and Expedite Superfund Cleanups and Process – A Welcome Change, we discussed the Task Force Report, issued on July 22, 2017, which identified 5 goals, 13 strategies, and 42 recommendations to (1) expedite Superfund cleanups; (2) re-invigorate responsible party cleanup and reuse; (3) encourage private investment; (4) promote redevelopment and community revitalization; and (5) engage partners and stakeholders. We have seen many of these recommendations realized, including the development and issuance of a priority list of Superfund sites targeted for immediate attention by Administrator Pruitt.

Recent EPA Realignment in Approval Process Sees the Administrator’s Role Expanding

In a recent shift to expand the influence of the Administrator’s Office, Administrator Pruitt issued a second memorandum on April 26, 2018 clarifying that EPA’s Office of Land & Emergency Management and regional offices should “coordinate and consult with the Administrator’s Office early on when developing” other significant actions (in addition to remedies) related to costly Superfund cleanups. Such actions would include Amendments to Records of Decision (“ROD”) or Explanations of Significant Differences (“ESD”) that are projected to either increase the estimated cost of a remedy to greater than $50 million or are projected to increase the estimated cost of a remedy that is already greater than $50 million by any amount.

The memorandum also specifically notes that consultations should occur when developing Non-Time-Critical Removal Actions (“NTCRA”) estimated to exceed $50 million. As in the earlier 2017 memorandum, Administrator Pruitt says the additional coordination and cooperation will result in “more accountability and consistency throughout the EPA’s regions.” What this means for potentially responsible parties (“PRPs”) at large Superfund sites is that Administrator Pruitt will play an increasingly important role in the decision-making process.

Neither memorandum addressed any change in the role of the National Remedy Review Board (“NRRB”) and the interplay between the NRRB and the increasing oversight and decision-making role of Administrator Pruitt. The NRRB is an internal EPA peer review group that reviews and comments on remedial actions and NTCRAs costing more than $25 million. Questions remain whether the NRRB only reviews actions costing between $25 and $50 million, as not to impede Administrator Pruitt’s review, or do both NRRB and Administrator Pruitt review actions costing in excess of $50 million?

Uncertainty in the Superfund Program

This step comes amid increased turmoil and uncertainty in the Administrator’s Office and the Superfund program. Administrator Pruitt’s top advisor on the Superfund program and chairman of the Superfund Task Force, Albert “Kell” Kelly, resigned unexpectedly in early May, leaving questions regarding who will run the approximately $1 billion program. Further, Administrator Pruitt himself is facing numerous investigations into his own actions and ethical violations; causing many to wonder just how much longer he will be in his current job and whether he will see any of these policy changes implemented.

It is easy to see, therefore, why every decision from the Administrator’s Office comes under significant scrutiny. Many opponents believe these moves are simply ways to reduce costs and time in the cleanup process, and they question whether “expedited” cleanups actually mean less rigorous cleanups. In his first year or so, there are examples where Administrator Pruitt has approved strengthened measures and cleanup requirements at some sites, despite pushback from industry and companies involved in the cleanup, but there are also examples of site decisions that cast doubt on his ability to be independent and impartial. In any case, as long as Administrator Pruitt is in his current role, it is clear that the Superfund program will see continued change and that he will use the authority of that role to expedite cleanups.

EQM awarded $45 million remediation contract by USACE

Environmental Quality Management Inc. (EQM, Cincinnati, Ohio) has been awarded a $45 million cost-plus-fixed-fee contract by the U.S. Army Corps of Engineers, New England District for environmental remediation services at the Callahan Mine site in Maine. The first Task Order will be issued in June for over $6 million.

The former Callahan Mine site was an open-pit mine developed in Goose Pond, a shallow tidal estuary of approximately 75 acres in the town of Brooksville, Maine.  From 1968 through 1972, approximately five million tons of waste rock and 800,000 tons of ore-bearing rock were mined from the open pit.  The waste rock was disposed of on site in three large piles and was also utilized to create a dam for the tailings impoundment.   In summary, the major work elements are remediation of the tailings impoundment; remediation of waste rock pile #3; slope stabilization of the tailings impoundment; consolidation and capping of the tailings impoundment; sediment excavation and disposal in a confined aquatic disposal cell; remediation of residual contamination at waste rock pile #2 and the ore processing area; and site restoration, mitigation, and monitoring.

Tax rebate to fund $8.6M cleanup of former Kitchener Frame site

by Catherine Thompson, Waterloo Region Record

As reported by Catherine Thompson in the Waterloo Region Record, It’ll cost about $8.6 million to rid the soil and groundwater of contaminants at the former Kitchener, Ontario Frame site.

The huge industrial site at Homer Watson Boulevard and Bleams Road has been undergoing cleanup for the past three years. The soil and groundwater were contaminated with petroleum hydrocarbons, volatile organic compounds, metals, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), contaminants that are often found at former industrial sites.

The city and the developers — Gary Ball and Marty Pathak — are keen to see the site redeveloped, said Rob Morgan, the City of Kitchener’s co-ordinator of development of former industrial sites. The site of the auto parts plant variously known as Budd Canada, ThyssenKrupp Budd Canada and Kitchener Frame, has been vacant since 2009.

Redevelopment of the sprawling 32-hectare site will give a big boost to the city’s supply of industrial land, Morgan said. About 16 hectares are slated industrial, 10 hectares are retail and 1.5 hectares are office. Another four hectares will be used for things like roads and storm water management.

“It’s much-needed land,” Morgan said. “Kitchener doesn’t have a lot of vacant industrial land left to offer.” There’s a couple of parcels, on Shirley Avenue and Strasburg Road, but not much else, he said.

The developers have applied to the city and region for grants under a program to encourage remediation of contaminated land.

The former Kitchener Frame site would be the biggest property ever to apply for the program, Morgan said.

Under the program, a developer cleans up a site and redevelops it. The new development generates far more taxes than the vacant land had. The city and region hand over the additional tax revenue to the developer for a set number of years, to repay the cost of the environmental cleanup.

The site now has an assessed value of $8 million, and generates about $108,000 in property taxes a year, split roughly 40-60 between the city and the Region of Waterloo. Once it’s cleaned up and redeveloped, it’s expected to have an assessed value of around $112 million, and generate $2.2 million in municipal property taxes.

“It’s a great program,” Morgan said. In exchange for foregoing the increased taxes for a certain number of years, the city gets vacant land cleaned up and converted to a productive use that generates more taxes and jobs.

“These lands are sitting dormant, contaminated, sometimes for many years. As a resident I’d rather see it cleaned up and earning money for the tax base.”

The Kitchener Frame site will be split into 11 different parcels from 1.3 to 10 hectares. Kitchener doesn’t expect to see the first new development on the site until about 2020, and development could continue for the next 10 or 15 years beyond that.

Morgan thinks it’s likely the property will be developed well before then, though. “They’ve got a lot of interest in that property. It’s a great location, because of its proximity to the 401; you’ve got a lot of variety in the lots; Kitchener has a strong manufacturing base, and we’ve got a lot of skilled workers.”

City staff are recommending that Kitchener council approve the application, which must also be approved by regional council, likely in June.

Controlling cleanup costs for contaminated land

by Dr. Harm Gross, Western Investor

As reported by Dr. Harm Gross in the Western Investor, in British Columbia, the cost of contaminated site cleanup has grown steadily since the Contaminated Site Regulation became law on April 1, 1997. There are several reasons for this change, some of which are under the control of “persons responsible”, chiefly landowners.

An uncontrollable cost factor is the proliferation of regulations, which ballooned to an estimated 10,000 double-sided pages in British Columbia. On November 1, 2017, Stage 10 omnibus amendments to the CSR came into effect, changing concentrations deemed harmful for a broad range of contaminants and adding a significant number of new ones. This meant that work before that date would become non-compliant overnight, causing environmental consulting companies to rush over 100 submissions for a Certificate of Compliance before this deadline to grandfather their work and avoid additional costs for their clients.

Regulations pertaining to contaminated sites are not just evolving in British Columbia, but have seen substantial updates across Canada in recent years.

Saskatchewan’s updated Environmental Management and Protection Act came into effect in June 2015. This legislation thoroughly overhauled the old Act by introducing a new impacted sites registry and by providing the regulator with more power to order persons responsible to conduct site assessments.

New guidelines were also introduced in Alberta, where the regulator released a new Environmental Site Assessment Standard in March 2016.

Manitoba enacted amendments to the Province’s Contaminated Sites Remediation Regulation in April 2014. While the intended aim of these new regulations and guidelines is to move the focus towards results-based frameworks, any change and expansion of rules inevitably leads to uncertainty for stakeholders. Uncertainty particularly stems from the need of establishing precedent with the regulator when the new rules are applied in the real world. It is up to the consultant to successfully navigate their clients through the new reality and reduce uncertainty. The consultant’s knowledge of the regulations, and proficiency in correctly interpreting and applying new rules, can have significant impacts on the accuracy of cost estimates and actual costs for site assessments and remedial work.

With regulations in flux and frequent changes in rules, the potential for lowering and accurately predicting costs for site remediation projects is thus of great interest to responsible persons. The potential savings by inviting an experienced review of proposed remediation plans can be significant. At one site the savings for a client was $15 million; more commonly, savings are in the 6-figure or low 7-figure range. Incorrect investigative work is the most frequent source of error. This ranges from faulty field techniques when sampling groundwater wells, through unfamiliarity with laboratory methods for distinguishing man-made from naturally occurring substances, to inadequate comprehension of the myriad environmental regulations. Investigating contaminants requires great care when the difference between contamination and no contamination is measured at the extremely low concentrations of parts per million in soil, or the even lower concentrations of parts per billion in water. We have seen numerous examples where mistakes have tarred a site.

The public sector is no less prone to erroneous estimations of remediation cost. In April 2014, the parliamentary budget officer reported that the federal government has underestimated the cost of cleaning up contaminated sites under its jurisdiction by at least $2 billion, putting the total liability for contaminated sites to almost $7 billion. This was due to the fact that many sites in the inventory had yet to be assessed. While it seems relatively self-evident that proper site investigations are a prerequisite and absolute must for cost estimates to be accurate, such oversights are unfortunately abundant in the private sector. All too often consultants provide flimsy cost estimates based on incomplete or deficient investigative data.

Businesspeople frequently complain about the irritation of unreliable cost estimates, and rightfully so – nowhere is this more prevalent than in the environmental consulting industry.

Technical experts are often loathe to accept responsibility for cost estimates for fear of finding undiscovered contamination, running into regulatory snafus or overlooking issues which later prove substantial.

Next Environmental has taken the unprecedented step of providing fixed price quotes for a comprehensive scope of work at each step of investigation or remediation, thus entirely eliminating the cost uncertainties for clients. This service, unique in the contaminated sites business, is possible due to the skillful application of regulatory proficiency to address the business needs of clients. Time will tell whether this cost control measure spreads to other firms.

Clean-up of Radioactive Material in Port Hope Finally Underway

After decades of study and planning, the clean-up or radioactive contamination in the community of Port Hope, Ontario is finally underway.  The Town of Port Hope, located approximately 100 km (60 miles) east on Toronto on Lake Ontario, has an estimated 1.2 million cubic metres (1.5 million cubic yards) of historic low-level radioactive waste scattered at various sites throughout the town.

The contaminated soil and material will be excavated to moved to the LongTerm Waste Management Facility, which is essentially an engineered aboveground landfill where the waste will be safely contained, and the long-term monitoring and maintenance of the new waste management facility.

Other historic low-level radioactive waste – primarily soil contaminated with residue ore from the former radium and uranium refining activities of Eldorado Nuclear — and specified industrial waste from various sites in urban Port Hope will be removed and safely transported to the new facility.

The historic low-level radioactive waste and contaminated soil, located at various sites in the Municipality of
Port Hope, are a consequence of past practices involving the refining of radium and uranium by a former federal Crown Corporation, Eldorado Nuclear Limited, and its private-sector predecessors. These waste materials contain radium-226, uranium, arsenic and other contaminants resulting from the refining process.

The historic waste and surrounding environment are monitored and inspected regularly to ensure the waste does not pose a risk to health or the environment. As part of the Port Hope Area Initiative (PHAI) construction and clean-up phase, the waste will be excavated and relocated to the new Port Hope long-term waste management facility.

In an interview with CBC, Scott Parnell is the General Manager of the Port Hope Area Initiative, which is in charge of the cleanup. He says that after decades of planning, the first loads of an estimated 1.2 million cubic metres of historic low-level radioactive waste will be on the move.

Scott Parnell, general manager of the Port Hope Area Initiative, stands near the town’s harbour.

“There’s been a lot of planning a lot of studies a lot of determination into how to approach the work safely, but this will be the first time we will be removing waste from the community,” said Parnell, who has overseen similar operations in Washington state and Alaska.

The $1.28-billion cleanup operation is a recognition by the federal government that the waste is its “environmental liability.” The radioactive tailings were the byproduct of uranium and radium refining operations run by Eldorado, a former Crown corporation, between 1933 and 1988.

Parnell says that the tailings were given away for free, which helps explain how the contamination was spread through the town.

“So, basically they offered it up and it was used for fill material to level up people’s backyards, for building foundations, for those kinds of things. So, that’s how the material got spread around the community,” Parnell said.

Parnell says an estimated 800 properties may be affected, but says there’s no indication the low levels of radiation are dangerous.

“There’s little human risk associated with the waste that’s identified here in Port Hope,” he said.

The first wastes to be remediated are currently stored under tarps at three locations including the Centre Pier, the Pine Street North Extension in the Highland Drive Landfill area and at the municipal sewage treatment plant. The Centre Pier is the first site to be remediated.

Mining company working with environmentalists to clean up old mining sites

As reported by the CBC, Calgary-based mining company Margaux Resources has announced a plan to clean up old tailings sites by using new mining technologies to extract the remaining minerals.

Tailings have long been known to cause environmental damage including loss of animal habitats and contamination of soil, groundwater and waterways.

Margaux has partnered with the Salmo Watershed Sreamkeepers Society — a non-profit engaged in protecting and maintaining the Salmo River in southeastern B.C.— for the remediation project.

“What we have here is an industry leader that is sympathetic and realizes the situation that historic mining efforts have left,” said Gerry Nellestijn, the coordinator of the Salmo Watershed Streamkeepers Society.

Margaux president and CEO Tyler Rice says the benefits are two-fold as the company hopes to profit from the extractions made.

“When this material was mined historically, they didn’t have 100-percent recovery of the elements … with advancements of technology we feel there is an opportunity to potentially extract the materials that weren’t fully recovered,” Rice said.

The first site scheduled for extraction and remediation is the Jersey-Emerald mine, located just outside of Salmo B.C., and once a large producer of tungsten.

Margaux has submitted an application to both the Ministry of Environment and the Ministry of Energy and Mines to take a bulk sample from the Jersey-Emerald site to, “assess the viability of remediating the tailings site and the potential to economically produce a marketable mineral concentrate,” according to a news release issued earlier this month.

Rice admits the site will likely not be fully remediated for a couple of years.

Meanwhile, the Salmo Watershed Society says there are over 40 tailings sites in the area and they are working to assess them.

“It’s an approach to actually go out there and assess tailings, size them, try to figure out what the pollution pathways may be, what the constituents of that tailing might be and look for remediation efforts that would be easy to implement,” said Nellestijn.

And both partners seem to be happy with the current government’s responsiveness to their project.

“We have a strong government that may very well be interested in participating with this kind of movement — it’s been a long time coming,” Nellestijn said.
