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.

U.S. Ninth Circuit Rules Military Contractor Liable on CERCLA Clean-up Costs

Written by: By Whitney Jones Roy and Whitney HodgesSheppard Mullin Richter & Hampton LLP

TDY Holdings, LLC brought suit for contribution under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) against the U.S. government relating to environmental contamination at TDY’s manufacturing plant. The district court granted judgment in favor of the government after a 12-day bench trial and allocated 100 percent of past and future CERCLA costs to TDY. On appeal, the Ninth Circuit held that the district court sharply deviated from the two most “on point” decisions regarding allocation of cleanup costs between military contractors and the U.S. government when it determined the cases were not comparable, clarified the applicability of those cases, and remanded the case to reconsider the appropriate allocation of cleanup costs between TDY and the U.S. government.

TDY (formerly known as Ryan Aeronautical Company) owned and operated a manufacturing plant near the San Diego airport

From 1939 through 1999, TDY (formerly known as Ryan Aeronautical Company) owned and operated a manufacturing plant near the San Diego airport. TDY’s primary customer was the U.S. government—99 percent of TDY’s work at the plant between 1942 and 1945, and 90 percent of the work thereafter was done pursuant to contracts with the U.S. military. The United States also owned certain equipment at the site from 1939 to 1979. Id. at 1006. Chromium compounds, chlorinated solvents, and polychlorinated biphenyls (PCBs) were released at the site as a result of their use during manufacturing operations. Id. In some cases, the government’s contracts required the use of chromium compounds and chlorinated solvents. Id. After passage of the Clean Water Act and other environmental laws classifying these chemicals as hazardous substances in the 1970s, TDY began environmental remediation and compliance at the site and billed the government for the “indirect costs” of that work, which the government paid. Id. at 1006–07. TDY incurred over $11 million in response costs at the site. Id. at 1007. Until the plant’s closure in 1999, the government reimbursed 90 to 100 percent of TDY’s cleanup costs at the site. Id. at 1007, 1010.

In 2004, the San Diego Unified Port District brought CERCLA claims against TDY. TDY and the Port District entered into a settlement agreement in March 2007 in which TDY agreed to cleanup releases at the site. TDY then brought suit for contribution under 42 U.S.C. § 9613(f)(1) and declaratory relief against the United States. Id. at 1007. The district court granted TDY’s motion for partial summary judgment declaring that the United States was liable as a past owner of the site under CERCLA. Id. After a 12-day bench trial on equitable allocation of costs, the district court held that the contamination caused by the hazardous substances at issue was attributable to TDY’s storage, maintenance, and repair practices, as well as spills and drips that occurred in the manufacturing process, rather than to the government’s directives to use the chemicals. Id. Accordingly, the district court allocated 100 percent of the past and future response costs for remediation of the three hazardous substances to TDY. Id. at 1008.

On appeal, TDY argued that the district court erred (1) when it allocated liability according to “fault”; (2) that the government’s role as owner rather than operator should not have been a dispositive factor in the court’s allocation, and (3) that the government should bear a greater share of response costs because it specifically required use of the chemicals at the site. Id. The court of appeals summarily rejected TDY’s first two arguments, but found that the district court did err in its analysis and application of binding authority on point: United States v. Shell Oil Co., 294 F.3d 1045 (9th Cir. 2002) and Cadillac Fairview/California, Inc. v. Dow Chem. Co., 299 F.3d 1019 (9th Cir. 2002). Id. at 1008–09. Shell Oil and Dow Chemical each produced products to support the U.S. military during World War II and incurred liability for contamination caused by hazardous chemicals that the government required to be used. In both cases, the Ninth Circuit affirmed the district courts’ allocation of 100 percent of cleanup costs to the government because “the contractors’ costs were ‘properly seen as part of the war effort for which the American public as a whole should pay.’” Id. at 1009.

The Ninth Circuit disagreed with the district court’s conclusion that Shell Oil and Cadillac Fairview were not comparable, but agreed that some deviation from their allocations were appropriate. Id. The Ninth Circuit agreed that the government exercised less control over TDY than it did over Shell Oil Co. or Dow Chemical. In support of this determination, the court noted that the government was an operator, rather than an owner, of TDY’s site, that the government-owned equipment was removed from the site 20 years before TDY ceased operations, and that TDY’s own practices at the site caused the contamination. Id. at 1010. Furthermore, the district court properly determined that “industrial operations undertaken for the purpose of national defense, standing alone, did not justify allocating all costs to the government.” Id.

However, the Ninth Circuit held that, in allocating 100 percent of cleanup costs to TDY, the district court failed to consider that the government required TDY to use two of the three chemicals at issue beginning in the 1940s, when the need to take precautions against environmental contamination from these substances was not known. Id. Furthermore, the Ninth Circuit determined that “[t]he court’s acknowledgement of the evolving understanding of environmental contamination caused by these chemicals, and TDY’s prompt adoption of practices to reduce the release of hazardous chemicals into the environment once the hazards became known, further undercuts the decision to allocate 100 percent of the costs to TDY.” Id. The district court also failed to consider the parties’ lengthy course of dealing through 1999, when the government paid between 90 and 100 percent of cleanup costs at the plant. Id. Although “a customer’s willingness to pay disposal costs . . . cannot be equated with a willingness to foot the bill for a company’s unlawful discharge of oil or other pollutants,” the Ninth Circuit nevertheless determined it should have been a relevant factor in the allocation analysis. Id.

Activated Carbon-Based Technology for In Situ Subsurface Remediation

The U.S. EPA Office of Superfund Remediation and Technology Innovation recently published a fact sheet about an emerging remedial technology that applies a combination of activated carbon (AC) and chemical and/or biological amendments for in situ remediation of soil and groundwater contaminated by organic contaminants, primarily petroleum hydrocarbons and chlorinated solvents.  The technology typically is designed to carry out two contaminant removal processes: adsorption by AC and destruction by chemical and/or biological amendments.

With the development of several commercially available AC-based products, this remedial technology has been applied with increasing frequency at contaminated sites across the country, including numerous leaking underground storage tank (LUST) and dry cleaner sites (Simon 2015).  It also has been recently applied at several Superfund sites, and federal facility sites that are not on the National Priorities List.

The fact sheet provides information to practitioners and regulators for a better understanding of the science and current practice of AC-based remedial technologies for in situ applications. The uncertainties associated with the applications and performance of the technology also are discussed.

AC-based technology applies a composite or mixture of AC and chemical and/or biological amendments that commonly are used in a range of in situ treatment technologies.  Presently, five commercial AC-based products have been applied for in situ subsurface remediation in the U.S.: BOS-100® & 200® (RPI), COGAC® (Remington Technologies), and PlumeStop® (Regenesis) are the four most commonly used commercial products.  CAT-100® from RPI is the most recent product, developed based on BOS-100®.  One research group in Germany also developed a product called Carbo-Iron®.  The AC components of these products typically are acquired from specialized AC manufacturers.  These types of AC have desired adsorption properties for chlorinated solvents and petroleum hydrocarbons.  Different products also have different AC particle sizes, which determine the suitable injection approach and the applicable range of geological settings.

In Situ Treatment Performance Monitoring: Issues and Best Practices

The U.S. EPA recently released an issue paper (EPA 542-F-18-002) that describes how in situ treatment technologies may impact sampling and analysis results.  The paper discusses the best practices to identify and mitigate issues that may affect sampling and analysis.

The utility of monitoring wells for performance or attainment monitoring is based on the premise that contaminant concentrations measured in the wells are representative of aquifer conditions. However, during in situ treatment, various biogeochemical and hydrogeological processes and sampling and analysis procedures may affect the representativeness of the monitoring well and sample quality, which may not be adequately considered in current remediation practice.

A properly designed monitoring network that anticipates the distribution of amendments after injection would minimize impacts to monitoring wells.  However, predicting amendment distribution prior to injection is challenging such that impacts to monitoring wells are likely.

The purpose of The U.S. EPA issue paper is to:
• describe how in situ treatment technologies may impact sampling and analysis results used to monitor treatment performance; and
• provide best practices to identify and mitigate issues that may affect sampling or analysis.

The U.S. EPA issue  paper discusses eight potential sampling or analytical issues associated with groundwater monitoring at sites where in situ treatment technologies are applied. These issues are grouped under three topic areas:
• Issues related to monitoring wells (Section 2).
• Representativeness of monitoring wells (Section 3).
• Post-sampling artifacts (Section 4).

The paper presents issues that pertain to collecting water samples directly from a monitoring well and does not discuss the use of other sampling techniques, such as passive diffusion bags or direct push groundwater sampling.

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.
