The 8th Northeast Sustainable Communities Workshop is scheduled for March 15th2017 in Newark, New Jersey. Sponsored by the Brownfield Coalition of the Northeast, the workshop will is entitled Driving Revitalization Sustainably: identifying sustainable goals and strategies for revitalizing their communities and brownfields,
The conference brings together experts and attendees to discuss the most current and state-of-the-art approaches and strategies are unique and typically heard at other events. Past workshops have been attended by representatives from government, higher education, professional organizations, and laboratories, as well as attorneys, developers, contractors, and consultants.
The goals of the workshop are to break new ground, offer new ideas, and posit new concepts on the topics of sustainability, collaboration and leverage, contamination, resiliency, brownfields, technology, and their impact on community revitalization.
The workshop is known to for using PowerPoint presentations sparingly, having speakers that are concise, yet informative; and providing plenty of time in each session for dialogue between attendees, speakers, and moderators.

The U.S. Interstate Technology Regulatory Council (ITRC) recently published a guidance document on Long-Term Contaminant Management Using Institutional Controls (IC-1). The guidance document was developed in response to the recent growth in the number of contaminated sites in the U.S. that are being managed through the use of institutional controls (ICs).
ICs are a form of land use controls that provide protection from exposure to contaminants on a site. In contrast to engineered site remedies, ICs consist of government controls, proprietary controls, enforcement or permit mechanisms, and informational devices that limit land or resource use (thus protecting human health by controlling how the property is used).
The guidance manual includes a survey of current state practices for ICs, best practices for developing and managing ICs. As part of the manual, there is a downloadable tool that can be used to document critical information about an IC. This tool can help to create a lasting record of the site that includes the regulatory authority, details of the IC, the responsibilities of all parties, a schedule for monitoring the performance of the IC, and much more relevant information. The tool generates an editable Long Term Stewardship (LTS) plan in Microsoft Word.
A report United States Environmental Security Technology Certification Program (U.S. ESTCP) recently released a report that describes the testing of a new direct-push optical screening tool for high-resolution three-dimensional (3D) subsurface mapping of chlorinated solvent dense non-aqueous phase liquids (DNAPLs) in unlithified sediments.
Unlithified sediments are sediments that have not undergone lithification, a process whereby sediments are transformed into solid rocks. The sediments are still in loose form and have not become compacted by pressure.
The tool was field-tested at a formerly used defense facility in Massachusetts in fall 2013 (Geoprobe® delivery) and again in March 2014 (CPT delivery). The new tool, a laser-induced fluorescence (LIF) technology referred to as “DyeLIF™,” was developed and validated during this project and is now commercially available.
The DyeLIF probe functions by injecting an aqueous delivery fluid containing a proprietary hydrophobic dye through a small injection port that is situated below the LIF window. As the probe is advanced through the subsurface, the injected dye contacts the soil and quickly partitions into any present DNAPL. Standard LIF tooling is used to detect the dye-labeled chlorinated solvent DNAPLs. The fluorescent signature of un-solvated and solvated dye is sufficiently different.
The U.S. ESTCP is U.S. Department of Defense’s (U.S. DoD) environmental technology demonstration and validation program. The Program was established in 1995 to promote the transfer of innovative technologies that have successfully established proof of concept to field or production use. U.S. ESTCP demonstrations collect cost and performance data to overcome the barriers to employ an innovative technology because of concerns regarding technical or programmatic risk, the so-called “Valley of Death.”
Chlorinated solvents are among the most common organic contaminants detected in groundwater at US. DoD sites. The sources of these contaminants are often historical releases of DNAPLs. Unfortunately, chlorinated solvent DNAPL source zones are difficult to locate using conventional subsurface characterization technologies. Laser-induced fluorescence (LIF) tools are currently available for real-time, high-resolution mapping of petroleum hydrocarbon and coal tar-based NAPL source zones. These LIF tools do not work with chlorinated solvent DNAPLs because chlorinated solvents lack the aromatic structure responsible for the laser-induced fluorescence in coal tars and petroleum hydrocarbons.
The objective of the field demonstration was to provide a field-scale demonstration of the new DyeLIF tool for high-resolution subsurface mapping of chlorinated DNAPLs. The real-time, high-resolution profiles generated from the DyeLIF were then compared to profiles from high resolution vertical soil sampling with subsequent dye shake tests and quantitative laboratory VOC analysis.
No major implementation issues were identified during the field demonstrations. However, a key limitation for any direct-push technology is suitability of the geological conditions for direct-push probing, i.e. absence of cobbles or other conditions that would cause tool damage and preclude advancing the probes.
According to a recent scientific study, polar bears face chemical poisoning 100 times above levels considered safe for adult bears. The reason is that certain pollutants bioaccumulate in the environment.
A research article in the recent edition of Environmental Toxicology and Chemistryshows that the bioaccumulation of persistent organic pollutants (POPs) in the arctic ecosystem are playing havoc on the diet of polar bears.
Trace quantities of PCBs are still found in the blood of polar bears. Perfluorooctane sulfonate (PFOS) is also found in surprisingly high concentrations in polar bears. PFOCs are found in fire fighting foams, oil repellent paper, packaging and fabrics.
When a bear eats a seal, toxins are amplified 34-fold. POPs accumulate in in muscle rather than fat.
The polar bear population in the arctic is estimated to be at 26,000. Scientists estimate that number will fall by a third by the 2050’s due to the impact of climate change. It is uncertain if this new information on toxicity will impact the estimate.
New and emerging contaminants being found in polar bears can only reduce the number.
The U.S. Environmental Protection Agency (U.S. EPA) has selected 19 communities for approximately $3.8 million in funding to assist with planning for cleanup and reuse of Brownfield sites as part of the Brownfields Area-Wide Planning (AWP) program. Each recipient will receive up to $200,000 to engage their community and conduct planning activities for brownfield site reuse.
The grants will help communities plan improvements such as housing, transportation options, recreation and open space, education and health facilities, social services, renewed infrastructure, increased commerce and employment opportunities.
“The Area-Wide Planning grant program is an innovation initiated by the Obama Administration to empower communities to transform economically and environmentally distressed areas, including communities impacted by manufacturing plant closures, into vibrant future destinations for business, jobs, housing and recreation,” said Mathy Stanislaus, Assistant Administrator for U.S. EPA’s Office of Land and Emergency Management. “These grants provide the opportunity for communities to determine for themselves revitalization plans that best meet their vision and needs based on a rigorous analysis of market and infrastructure in a manner that benefits and does not displace long-term residents.”
Assistant Administrator Stanislaus announced the new AWP recipients for funding at a community event in Norfolk, Va.
The U.S. EPA’S AWP program was modeled after New York State’s Brownfields Opportunity Area (BOA) Program, which was developed by communities – particularly lower income communities – to enable them to drive development that meets their needs without displacing them. Studies have shown that residential property values near brownfields sites that are cleaned up increased between 5 and 15 percent. Data also shows that brownfields clean ups can increase overall property values within a one-mile radius. Preliminary analysis involving 48 brownfields sites shows that an estimated $29 million to $97 million in additional tax revenue was generated for local governments in a single year after cleanup.
This year’s selected recipients for funding are:
- Eastern Maine Development Corporation, Bucksport, Maine
- City of Providence, R.I.
- Isles, Inc., East Trenton, N.J.
- City of Wilmington, Del.
- Redevelopment Authority of the City of Harrisburg, Pa.

The Government of Alberta recently issued an Enforcement Order to Cherokee Canada Inc. which requires the company to clean-up hazardous waste at a former creosote plant in Edmonton.
The creosote plant had operated from 1924 until 1987 and was purchased by a numbered company in 2010 from Domtar. At that time, the plan was for residential development of the site.
As part of the redevelopment plan, a berm was built using contaminated materials from the site. In 2015, the government requested that the soil from the berm be analyzed.
The recent Order requires the company to submit a written sampling and contaminant delineation plan of the berm. A remediation plan must also be submitted.
Creosote is a thick, black, oily liquid that is a mixture of hundreds of chemicals. The major chemicals in coal tar creosote are polycyclic aromatic hydrocarbons (PAHs), phenol, and creosols. Creosote is the most common product utilized to preserve wood in North America and is also used as a pesticide. Mild exposure to creosote can result in breathing problems and skin irritation. Longer term exposure to creosote has been linked to cancer.
“First, we have to determine the nature of the contamination, and that would provide direction for how those sites would need to be remediated. Our concern is that the contamination on those sites be addressed,” Alberta Environment spokesman Jamie Hanlon said with respect to the Enforcement Order.
Alberta Environment said the site is proposed for a residential development. The department said the current site approval holders have failed to act upon numerous requests since last year for soil sampling results on the berm.
The United States Department of Justice (U.S. DOJ) recently announced that Bechtel National Inc., Bechtel Corp., URS Corp. (predecessor in interest to AECOM Global II LLC) and URS Energy and Construction Inc. (now known as AECOM Energy and Construction Inc.) agree to pay $125 million to resolve allegations under the U.S. False Claims Act. The U.S. DOJ alleged that the companies had made false statements and claims to the U.S. Department of Energy (U.S. DOE) by charging the U.S. DOE for deficient nuclear quality materials, services, and testing that was provided as the Waste Treatment Plant at the US. DOE’s Hanford Site near Richland, Washington.
The United States alleged that the defendants violated the False Claims Act by charging the government the cost of complying with these standards when they failed to do so. In particular, the United States alleged that the defendants improperly billed the government for materials and services from vendors that did not meet quality control requirements, for piping and waste vessels that did not meet quality standards and for testing from vendors who did not have compliant quality programs. The United States also alleged that Bechtel National Inc. and Bechtel Corp. improperly claimed and received government funding for lobbying activities in violation of the Byrd Amendment, and applicable contractual and regulatory requirements, all of which prohibit the use of federal funds for lobbying activities.
The settlement also resolves allegations that Bechtel National Inc. and Bechtel Corp. improperly used federal contract funds to pay for a comprehensive, multi-year lobbying campaign of Congress and other federal officials for continued funding of the Hanford Waste Treatment Plant. In its press release, the U.S. DOJ stated that the claims asserted against defendants are allegations only, and there has been no determination of liability.
Bechtel National Inc. and Bechtel Corp. are Nevada corporations. URS Corp. is headquartered in California and URS Energy and Construction Inc. is headquartered in Colorado.
The Hanford facility made more than 20 million pieces of uranium metal fuel for nine nuclear reactors along the Columbia River. Five huge plants in the center of the Hanford Site processed 110,000 tons of fuel from the reactors, discharging an estimated 450 billion gallons of liquids to soil disposal sites and 53 million gallons of radioactive waste to 177 large underground tanks.
Plutonium production ended in the late 1980s. Hanford cleanup began in 1989, when a landmark agreement was reached between U.S. DOE, the U.S. Environmental Protection Agency, and the Government of Washington State. Known as the Tri-Party Agreement, the accord established hundreds of milestones for bringing the Hanford site into compliance with federal and state environmental regulations.
The U.S. DOE has paid billions of dollars since 2002 to the defendants to design and build the Waste Treatment Plant (WTP). The WTP will be used to treat dangerous radioactive wastes that are currently stored at the Hanford Site.
The municipal government of the Cowichan Valley Regional District (CVRD) is appealing a court decision on Shawnigan Lake landfill to the Supreme Court of Canada. The CVRD wants the Supreme Court to order that the landfill be shut down and that deposited contaminated soil be removed. The landfill has a permit to operate that was issued by the British Columbia Ministry of the Environment.
A consortium of companies own and manage the landfill. The companies include South Island Aggregates (SIA), Cobble Hill Holding (CBH), and South Island Resource Management (SIRM). The existing permit, issued by the B.C. Environment Ministry permits the disposal of approximately 5 million tonnes of contaminated soil at the landfill.
The Shawnigan landfill is the site of a former quarry. The CVRD is of the view that existing zoning bylaws for the municipality does not allow the property to be used as a landfill.
In the spring of 2016, the British Columbia Supreme Court ruled in favour of CVRD. However, an appeal by the site owners to the B.C. Court of Appeal resulted in the lower court ruling being overturned. Now CVRD is taking the case to the Supreme Court of Canada.
In the view of CVRD, the local municipality should have the ability to control land use through zoning bylaws and without provincial interference. The Site owners are of the opinion that the quarry and landfill activity falls under provincial jurisdiction.
The consortium of companies that own and operate the landfill had 30 days to response to CVRD’s application to the Supreme Court to hear the case. A decision by the Supreme Court on whether it will hear the case is expected shortly.
CVRD is not only asking the Supreme Court to reverse the decision on use of the property as a landfill but also require the property owners to remove any contaminated soil that has already been deposited.
This manual, prepared under the U.S. Environmental Security Technology Certification Program (ESTCP), is a guide to the use of in situ reactive amendment technologies for remediation of contaminated wetland hydric soils. The manual provides a toolbox of methods with which to approach site characterization/monitoring, treatability testing and demonstration, and remedy implementation.
The following information can be found in the Guidance Manual:
(1) A repository of literature sources for active in situ remedial projects;
(2) A conceptual approach to managing the remediation of wetland hydric soils;
(3) Suggestions for project objectives, metrics, and evaluation criteria;
(4) A discussion of implementation means and methods; and
(5) An assessment of technology cost.
This guide is based upon a field demonstration conducted at Aberdeen Proving Ground, located in Aberdeen, Maryland, to determine the most effective amendment to immobilize PCBs in wetland sediments among the following agents: powdered activated carbon slurry (Slurry Spray), two pelletized AC products (AquaBlok® and SediMite™), and an engineered manufactured soil cover system (sand control).
