In Millsboro, Delaware, a proposed carbon-injection system for the generating units at a power plant is being greeted with concern from area residents. The carbon injection should remove mercury for air emissions: a good thing; but the mercury then must be mixed with fly ash: the concern. Residents would be more comfortable, they say, if the on-site landfill had a liner or cover. Learn more here.;

Four years ago, GSE Environmental formally announced the development of polyethylene geomembranes for use in applications with prolonged exposure to temperatures above 60°C (140°F). Now, the company has been...

The closed A and L Salvage site in Lisbon, Ohio is nearly capped. With about 25 percent of the synthetic membrane or plastic cap in place, the 42-acre project is expected to be finished by the end of October. In addition to the 40-mil geomembrane, 18 inches of dirt and grass will cover the hillside with elevations between 80 to 100 feet. Learn more here.;

The Army Corps of Engineers has awarded a $17.9 million contract to a construction firm in New Orleans to reinforce the flood walls and levees along the city's London Avenue Canal, which failed during Hurricane Katrina in 2005. The federal agency also approved a request by levee officials to paint all sheet piling with an anti-rust coating, a move that would ease concerns about rusting in the structures. Learn more here.;

Waste & Recycling News Capitol Hill Summit will convene at the Omni Shoreham Hotel, in Washington, D.C., on 30-31 March 2009. This 1-1/2 day summit will bring together environmental, waste and recycling executives from corporations both large and small, as well as companies that provide environmental services to corporate America. Co-organizer of the event is the environmental division of the law firm of Porter Wright Morris & Arthur LLP. View the list of speakers here. Learn more here.;

In 2014, Australia-based Geofabrics reported on Geosynthetica about the use of geotextile containers to protect a coastal zone's vital mangrove vegetation. As part of Geosynthetica's extended Earth Day celebration,...

Waterproof Membranes 2008 is underway. It's the second in what is anticipated to be a longer-term series organized by Applied Market Information (AMI). And there was something about the program for Waterproof Membranes 2008 that really caught our eye. Key subjects this year include green roofing, sustainability, membrane durability and geotechnical applications. Others in the geosynthetics industry and related construction industries have seen this too, as our first night at the event revealed. Read the report from the opening night's reception.

The number of permits issued for Concentrated Animal Feeding Operations (CAFOs) lags the number of approved operations, sometimes by a considerable margin. For example, in Wisconsin, a single CAFO permit covers 55 sites controlled by a corporation that specializes in turkey production. Prior to 2002, the state had issued permits for each site. This change in permitting means that the reported number of permitted operations fails to give an accurate picture of how fast the CAFO market, with its more severe waste management and runoff control needs, has expanded. CAFOs are large operations for beef, poultry, dairy, and pork production, generally raising more than 1000 animals on a single site. In California, some dairies have more than 3000 cows, and the amount of exposed waste has led to the dairy-rich San Joaquin Valley posting air-quality ratings as poor as Los Angeles' and Houston's. The US Environmental Protection Agency (EPA) and state regulatory agencies are particularly concerned with waste management and runoff control on barn-confined and open lot operations. (Pasture-grazing operations do not present the same immediate threats.) Still, CAFOs are the trend, even for former small farms as they struggle to compete. Needs in the industry: Better waste lagoon design, waste liners, lagoon containment covers (tied to methane harvesting systems) and runoff control methods affiliated with NPDES. Many CAFOs must file for National Pollutant Elimination Discharge System (NPDES) permits.

While specifications are to help provide stability, consistency and professionalism in engineering and construction, they can also lead to problems--especially when their authors do not seem to see the full implications of their assumptions. In example, Ian Peggs of I-CORP INTERNATIONAL writes about the placement of leak location in specifications and how some of these specs provide CQC but not real CQA. Errors of assumption like this may lead to facility failures.

Golder Associates Ltd. is pleased to announce Mr. Mark Brightman, as President of the firm's Canadian operations. Brightman replaces Mr. Brian H. Conlin, who was recently appointed as President & CEO of Golder Associates' global corporation. Read more in the release.

Geomembranes come in many forms: polypropylene, high-density polythylene, polyvinyl chloride, reinforced, non-reinforced, and many other forms. One of Canada-based Soprema's specialties is bituminous geomembranes, a class that is gaining ever-greater use in environmental, infrastruture and hydraulic applications. Learn more about this geomembrane class at Soprema's site. Learn more here.;

In Mansfield, Massachusetts, Compo Chemical Company is carrying out a multimillion-dollar cleanup of a 26.5-acre brownfield ahead of redevelopment. Volatile organic compounds (VOCs) are being extracted from excavated soil with a system that involves removing contaminated soil, storing it on an impermeable liner system, and drawing out the polluted vapors. Read about it in New England Construction. Learn more here.;

The International Erosion Control Association (IECA) has extended the window for proposals to EC10 through 29 May 2009. IECA organizes its work into 8 technology sections: slopes, stream restoration, vegetative establishment, stormwater management, wetlands, erosion and sediment control, beach and shoreline stabilization, and wind erosion. The "Hot Topics" for 2010 are LEED for new construction, sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation and design process. EC10 will be held in Dallas, Texas 14-17 February 2010. Read more at IECA's site. Learn more here.;

Bateman Engineering has commenced the engineering and procurement (EP) on the Maxi phase of the innovative greenfields Trekkopje project in the heart of Namibia's Namib Desert, some 65 km north-east of the coastal town of Swakopmund. The French nuclear giant AREVA, through its subsidiary AREVA Resources Namibia and AREVA Processing Namibia Pty (Ltd), is developing the world's first uranium mine to utilise an alkaline heap leach process. The heap leach pad will comprise 30 cells in total, of which about 22 will be active at any given time, while the remainder will be in various stages of construction (stacking), demolition (reclaiming), or maintenance per the OOHLP (On-Off Heap Leach Pad) method.

The Kandiyohi County Board of Commissioners (Minnesota) approved a conditional use permit Tuesday that could allow a privately owned demolition landfill to accept a wider range of items, including things termed "industrial waste." Jay Morrell Building Investments built the landfill to Class III standards by installing a clay bed and thick plastic liner. The leachate, or runoff from the landfill, is collected.
