Soil disposal comes with a pricetag: Residential and Civil Construction Alliance of Ontario report

KELLY LAPOINTE

staff writer

Due to rising costs and greater restrictions, up to 15 per cent of the costs of infrastructure projects will have to be dedicated to the disposal of excavated soil, found a new report released by the Residential and Civil Construction Alliance of Ontario (RCCAO).

“We hope we can work with the government in developing clear, consistent, pragmatic rules for managing excavated soils in Ontario,” said RCCAO executive director Andy Manahan. “This represents a significant opportunity to reduce construction costs and stretch public infrastructure dollars.”

With the amount of projects that are currently going on in Ontario, the quantity of excess construction soil is likely to increase greatly in the coming years, says the report. Municipalities are increasing restrictions or introducing bans on the importation of fill and soil from outside their boundaries, which can result in higher transportation costs and increased greenhouse gas emissions as excess soils will have to be transported longer distances, says the report.

Report author, consultant and environmental lawyer Frank Zechner, says these unnecessary and added costs represent “a significant erosion of taxpayers’ dollars that would otherwise be available for badly-needed infrastructure improvements.”

The report, Eglinton LRT Project: Estimated Costs and Impacts of Addressing Excess Construction Soils, looked at the first phase Metrolinx Eglinton Crosstown Light Rail Transit Project in Toronto which could result in the displacement of approximately 1,500,000 cubic metres of soil and fill.

The study estimates that managing the excess soils for this project could cost be $65 million to over $100 million, depending on variables such as distance, loads and landfill costs. Manahan pointed out that this estimate assumes the cleanest Table 1 soils and said it’s more difficult to find a place for Table 2 or 3 soils.

“Barring options such as the creation of artificial islands in Lake Ontario, the only large-scale sites that can likely accommodate fill quantities in excess of 100,000 cubic metres are landfills,” says the report.

Another project, the City of Toronto’s own water and sewer capital program, will produce more than 800,000 cubic metres between now and the end of the decade.

Manahan said the RCCAO and others in construction have been warning the province about the issue for years. RCCAO has established a steering committee to develop construction industry best practices for managing excavated soils.

“Cumulatively, all of the infrastructure projects out there the big and the small are really going to be problematic if you don’t deal with solutions,” he said.

This report is in addition to various RCCAO ads about excess construction soils.

“I want to keep the pressure on,” said Manahan.

“This isn’t going away, so let’s keep on talking about solutions.”

Manahan pointed to the province of Quebec, which views soils as a beneficial reuse.

“It’s not something that’s treated as garbage that’s thrown away; it’s something that can be reused. If there are trace elements of salt, it can still be reused. It’s not something that’s going to create a landfill pile,” he said.

Manahan added that is the fundamental principle he would like to see the government adopt, but it would require regulatory changes.

At the end of June the Town of East Gwillimbury, Ont., requested that the province, through the Ministry of Environment (MOE), “establish regulations and a provincially regulated approval process to govern the quality of fill imported to a receiving site other than for the purpose of Brownfield redevelopment,” it said in a letter to the Association of Municipalities of Ontario (AMO).

RCCAO recommends that the province of Ontario “establish a pragmatic, risk-based, and affordable framework that distinguishes excess construction soils, particularly those from municipal roads and rights of ways, from historic industrial hazardous wastes which are the primary focus of laws such as Ontario Regulation 153/04,” says the report.

Terrapin Turtle Rescue


The Wetlands Institute is a private, non-profit organization located on salt marshes of the Cape May Peninsula in southernmost New Jersey. Its mission is to promote appreciation of the vital role wetland and coastal ecosystems play in the survival of life on this planet. Since its founding in 1969, the Wetlands Institute has routinely involved undergraduate students in a wide variety of research projects pertaining to coastal environments and the organisms inhabiting them. The focus of the research is Conservation Biology. See the Coastal Conservation Research Program (CCRP). To see more of the activities of the CCRP, visit its Facebook page.

Diamondback Terrapin Conservation
Since 1989, the Wetlands Institute, in cooperation with The Richard Stockton College of New Jersey, has conducted a diamondback terrapin conservation project. Each summer, college and university students come from all over the United States to assist these creatures that are so desperately in need of our help. International Student Researchers from Asia began joining the program in the year 2000. All of these researchers are joined in their efforts by a small group of dedicated local volunteers.

Diamondback Terrapins — A Beleaguered Species
For well over a century, diamondback terrapins, the only species adapted to life in the brackish waters of coastal salt marshes, have been adversely affected by a variety of human activities. A century ago, overhunting of the northern diamondback terrapin, Malaclemys terrapin terrapin — considered a gourmet delicacy — nearly extirpated populations in many parts of its range. Eventually, the combined effects of Prohibition (sherry was considered an essential ingredient of terrapin stew recipes) and the economic stresses of the Great Depression in the 1930s brought an end to significant commercial exploitation of terrapins. It was not until nearly the late 1960s that terrapin populations

recovered to a level approaching their former “pre-gourmet” abundance. More recently, however, two other threats to terrapin populations have arisen. Coastal development has led to considerable habitat destruction, especially of traditional nesting sites on barrier beach islands. Along the Atlantic coast of New Jersey, the search for alternative nesting sites on highway embankments has resulted in large numbers of roadkills every nesting season. And the loss of terrapins to the commercial crabbing industry, through drowning in crab traps, has increased dramatically.

The Terrapin Conservation Project
The serious declines in southern New Jersey’s terrapin population, due to increased mortality from roadkills and drowning in crab traps, prompted the launching of the Terrapin Recovery/Conservation Project in 1989. Under the direction of Dr. Roger Wood, the program has developed techniques to incubate and hatch eggs recovered from road-killed terrapins, after which the hatchlings are head started and released. In addition, the program’s ongoing studies have proven the effectiveness of terrapin excluder devices to prevent drowning in crab traps.

Hands-on Conservation — Recovering Eggs from Roadkills
Research interns will work closely with Dr. Wood and the Wetlands staff to receive a practical laboratory and field course in hands-on conservation. This will include round-the-clock road patrols during the terrapin nesting season in June and July, to minimize the number of roadkills of nesting females, as well as the removal of potentially viable eggs from the carcasses of roadkills. Eggs are incubated and, after hatching, head-started at the Richard Stockton College “turtle farm.” Head-started turtles (hatched from the previous season) are weighed, measured, marked (with a microchip PIT tag injected just beneath the skin in front of the rear leg), and released into the salt marsh. For more information see Terrapins and Tires.

Drowning in Crab Traps
Commercial crab traps are widely used throughout the range of diamondback terrapins. Experiments on the Cape May Peninsula in southernmost New Jersey and elsewhere show that crab traps catch significant numbers of terrapins of both sexes, including both juveniles and adults. Unfortunately, substantial proportions of these terrapins drown before the traps are pulled for the daily crab harvest. In fact, incidental capture and drowning in commercial crab traps is the number one killer of diamondback terrapins in New Jersey, with deaths estimated at 14,000–15,000 per year in the mid-1990s. It is likely that considerably larger numbers of terrapins are killed throughout this species’ entire Atlantic and Gulf coast range every year.
Many of these deaths can specifically be attributed to ghost crab traps, which are derelict traps that have been lost or abandoned and are no longer being checked and emptied of their catches. It is estimated that 2 million crab traps are commercially and recreationally used annually, with approximately 25 percent of those traps becoming lost or abandoned. In the summer of 2000 a student researcher removed 32 ghost traps from the vicinity of the Wetlands Institute, many of which contained dead terrapins; one contained at least 15. In 2007, over a 13-day period, a student researcher located and removed 41 ghost traps from the salt march creeks and sounds. The ghost traps contained at least 41 dead terrapins and various other marine organisms, including 37 blue crabs. Only four of the 41 ghost traps were equipped with Terrapin Excluders Devices (TEDs), which are designed to reduce bycatch of terrapins. This source of terrapin mortality could be greatly reduced if regulations to prevent bycatch were strengthened. Terrapins and other marine animals would also benefit from the organization of large community trap removal efforts.

Terrapin Excluders
Considerable effort has also been devoted to the development and testing of the terrapin excluders for commercial crab traps. In 1992 a rectangular wire excluder device was developed to fit into the inner (narrow) end of entrance funnels in a typical commercial crab trap. This device was designed to prohibit the entry of most terrapins yet not impair the number or size of crabs caught. Results from the program’s long-term studies have been very positive: not only have the excluders greatly reduced the number of terrapins caught in modified traps, they have also actually increased the crab catch over unmodified traps of standard design. Three states (New Jersey, Maryland and Delaware) have adopted regulations mandating the use of terrapin excluders under certain circumstances. For more information see Terrapins and Traps.

Barrier Fencing Project
Increased motor vehicle traffic on the causeways between the mainland and the barrier islands of coastal southern New Jersey is a growing threat to diamondback terrapins. Development on the barrier islands has destroyed most of the sand dunes that originally served as the primary nesting site for terrapins. With the disappearance of sand dunes,

females have had to find alternative nesting grounds, primarily the shoulders of roads crossing and adjacent to their native salt marshes. Embankments of causeways have proved to be a dangerous substitute for sand dunes, resulting in hundreds of terrapin roadkills annually.
In 2004 researchers from the Wetlands Institute began to install temporary silt fencing along the coastal causeways, in an attempt to reduce road mortality of nesting terrapins in areas known to be major “kill zones.” For three summers, the fencing along Stone Harbor Boulevard reduced terrapin mortality, on average, approximately 84 percent. In 2006, in an attempt to improve the fencing project, a 1,000-foot section of a new fencing material, “Tenax” (a thick, mesh material), was installed to determine its durability in the harsh coastal conditions over the course of a year. The Tenax proved to be durable, so in 2007 the Wetlands Institute installed the year-round Tenax fence along the entire section of Stone Harbor Boulevard. In addition, the fencing project was expanded to include a mile and a half section of Avalon Boulevard (using a combination of both Tenax and silt fence material), which, because the fence was installed in a continuous line with no openings, resulted in a 100 percent reduction of terrapin roadkills.
By 2009 the Tenax fencing, susceptable to snow damage from plowing and damage from weed whackers, was also showing signs of deterioration. Six-inch corrugated plastic drainage pipe was proven experimentally to be an effective barrier, and in June 2010 over 7,000 feet of corrugated tubing was installed along the Margate Causeway. It proved much quicker and easier to install than either silt or Tenax net fencing. See A Guide for Building Terrapin Barriers and Fences.

Predator Exclosures

Two predator exclosures constructed
around terrapin nests

From the end of May to late July, female terrapins emerge from the marsh to nest on high ground, digging a 6–8 inch hole and laying approximately 8–12 eggs. Numerous terrapin nests are preyed upon each summer, particularly along the Wetlands Institute’s nature trail. To help reduce this loss, we construct predator exclosures (black mesh cages) over the nests to protect the eggs from various predators such as raccoons, skunks, and foxes. In 2008 we constructed 50 predator exclosures along the nature trail. To locate terrapin nests, student researchers regularly walk the vicinity of the Wetland Institute and the nature trail, searching for nesting terrapins. When they come across a terrapin, they wait patiently until the nest is completed. A predator exclosure is then constructed over the nest, and the turtle is retrieved to be microchipped for future identification. In 50–90 days terrapin hatchlings emerge from the nests. In the fall and in the spring (as some hatchlings overwinter in the nest), Wetlands Institute staff monitor the predator exclosures several times a day to remove emerged hatchlings and record measurement data. We release the hatchlings at night so they don’t become instant gull food!

Diamondback Terrapin Sonic Telemetry
In 2005, the Wetlands Institute’s began conducting a sonic telemetry study, attaching small coded transmitters to adult diamondback terrapins. The transmitter sends a unique signal through the water to a receiver that is attached to a buoy located in the marsh. Each time a terrapin swims by an underwater acoustic receiver, information is recorded. We then use the information collected by the receiver to determine where a terrapin is, how far it moves, and how long it takes to move from one location to another. This information is extremely valuable because little is known about terrapin movements (particularly because females leave the water only during the nesting season and males barely ever leave the water other than to bask in the sun).

Currently, we have 9 receivers strategically placed throughout the marsh, specifically near the mouths of creek openings. Over the past four years, 65 terrapins have been fitted with mobile transmitters (Vemco V9-2L-R04K coded pingers), attached to the margins of their shell and then released back into the salt marsh. Results so far show that there is considerable individual variation in the movements of different terrapins.

Each summer school groups are given the
opportunity to release head-started terrapins
that have hatched from eggs retrieved
from road-killed terrapins.
Community-based Conservation — Public Education
New Jersey terrapins are in serious trouble. But we are the ones who invaded their territory. It is up to us to ensure their survival. When you see a terrapin crossing the road: slow down, stop, pick her up, cross her in the direction she was traveling, and wish her good luck. We hope that by educating the public and continuing with our conservation project, the diamondback terrapin will again thrive in the region’s salt marshes.

A good way you can help:
Adopt a terrapin!

eggs retrieved from road-killed females, are

Illinois Drinking Water


Illinois Residents Left Wondering About Vinyl Chloride Contamination
Posted: 31 Aug 2012 09:00 AM PDT
By: Duane Craig

Residents of Sauk Village, Ill. want some answers about vinyl chloride that has been contaminating their water since 2009, but there have been few answers coming their way, according to this article, and this one.

During June and July 2012, crowded, anger-infused public meetings resulted in one of them being shut down as people accused the local government and the state of not providing enough information on the dangers of the contamination. Distressed residents also wondered why so little had been done since the pollution was discovered three years ago.

By early August 2012, air strippers were operating at the village’s wells #1 and #2, and seven test wells were planned for installation throughout August to sample water and determine not only contamination levels but also the direction contamination is moving through the ground, according to this Illinois document.

Environmental officials don’t know the source of the contamination and have said that it may never be known. But the lack of that information hasn’t been as contentious as the lack of reliable and consistent information on when it was safe to use the water and when it was not safe. At one time residents were told that officials could not confirm whether the water was safe. Part of that issue stems from Environmental Protection Agency guidelines on vinyl chloride in water. The agency sets a limit of 2 parts per billion as the action level — the amount of the contamination that requires action to reduce its presence. The EPA however also states that no amount of vinyl chloride is safe in drinking water. Meanwhile, Illinois has an action level of 1 ppb as a safety level to ensure contamination is caught in time to take action before it reaches the federal limit.

Other concerns arose over the nature of vinyl chloride. As a volatile organic compound it easily transfers to air, posing vapor intrusion risks in buildings where it can be inhaled by occupants. That same characteristic is what makes it easier to deal with by stripping it out into air in specially-designed water cleaning systems. Still, residents have been left wondering about their exposure to the water during the time it was not being treated. Those concerns extended to uses other than for drinking, such as using it for bathing, washing dishes and boiling foods. Businesses, especially restaurants, had received conflicting guidance that left them wondering if their premises were safe, or whether they should be serving food. Even after treatment, questions remain about safety if any of the contaminant still remains, even amounts below the state’s action level.
