The Importance of Levees

0
While those levees don't necessarily protect all the people living in the 881 counties that have them, a study for Levees.org by geographer Ezra Boyd concludes that the levees more than pay for themselves when their cost is compared to the investment they protect. Counties with levees account for only 28 percent of the nation's counties and only 37 percent of the nation's land area. But they contain 55 percent of the nation's population, more than 156 million people, according to the study. Learn more here.;

Credits for Lagoon Covers

0
The lagoon cover at the Miedema Dairy in Ohio blankets a 350-by-160-foot section of a 350-by-305-foot lagoon. Liquid manure enters the lagoon at the covered end and gradually flows toward the uncovered section. The cover is made of 60-mil, high-density polyethylene (HDPE) geomembrane. A new program coordinated by the Environmental Credit Corp. offers farmers a way to finance manure lagoon covers by selling carbon credits. Read about it here (PDF). Learn more here.;

EPA Cleanup Cost Rules to Affect Chemicals, Petroleum and Power Generation Industries

0
The U.S. Environmental Protection Agency has taken a significant step in an effort to help reduce the need for federal taxpayers to fund the cleanup of environmental releases. The agency has identified three additional industry sectors for which it will begin the regulatory development process for any necessary financial assurance requirements: the chemical manufacturing industry; the petroleum and coal products manufacturing industry, which primarily includes refineries and not coal mines; and the electric power generation, transmission, and distribution industry.

Mining in Tanzania: Still a Concern

0
Following heavy rains in May, water from a storage pond at the North Mara gold mine seeped through the walls of a storage pond. Barrick Gold, owners of the facility, have had to deal with multiple acts of theft and vandalism at the site, including sections of liner (in use!) being stolen. Some locals maintain the mine has caused the death of fish, crops and animals. Up to 1000 cattle have been said to have died--but no evidence has been offered in support of the allegations. It's a difficult situation, to say the least. Learn more here.;

Aluminum Processors Seek New Landfill

0
Two aluminum-processing industries in Tennessee have submitted preliminary plans to construct a landfill behind the county airport, a proposal similar to one two years ago that was voted down by commissioners. The 95.2-acre landfill proposed by Tennessee Aluminum Processors Inc. and Smelter Service Corp. will be discussed at a city planning commission meeting on 5 January 2010. Any aluminum by-product would be separated from the groundwater by a 12-inch thick leachate collection system, a 7-foot clay buffer, two high density polyethylene liners and a clay liner, according to the plans.

A Disappointing Gift from the EPA: Coal Ash Delay

0
Just in time for the holidays, the US Environmental Protection Agency (EPA) has delayed its decision on coal ash storage and facility design. It was anticipated that a rule would have been proposed in 2009, but the agency has asked for a bit more time. One of the solutions that many are hoping for is a requirement for geosynthetic lining systems. With landfills, required lining systems have made waste management the United States' best-rated infrastructure zone. Coal ash disposal would benefit from that care.

Rehabilitation of Geotextule Tubes in Dune Protection

0
Geotextile tubes--in varying layered designs--were used in a dune stabilization project in Leirosa, Portugal. When some areas of the pyramidal design split after uncharacteristically high tides, geotextile rehabilitation was conducted with design and technical support provided by NAUE. Read about the redesign strategy in a special issue of the Journal of Coastal Research (2009), from the ICS 2009 event. Learn more here.;

Landfill Gains 10-Year Extension…and a Big Fine

0
The Chrin Bros. Sanitary Landfill near Allentown, Pennsylvania has been granted a 10-year renewal of its state permit to operate in Williams Township, but it has also been fined $187,500 for odors and other environmental violations. The permit allows Chrin to continue running the 73-acre landfill through 2019. It also requires 18 acres of open landfill to be capped temporarily to collect gases and control odors. Chrin this month installed a plastic geomembrane to cap 7.4 acres and has agreed to cap an additional 10.5 acres by the end of 2011. Altogether, the temporarily capped areas and the already permanently capped 27.1 acres will account for 60 percent of the landfill's area of operations. Learn more here.;

Leaky Dam to Go Geosynthetic?

0
The Canyon Creek Meadows Dam in Oregon is leaking. It's reservoir, which is now only filled with seasonal precipitation, has been prone to leaks since the 1960s when it was constructed. Locals would like to save the structure, but to do so will require improving the reservoir. Failure to do so will lead to either decommissioning the hydraulic structure or structural failure. Repair strategies being debated include lining the reservoir or even creating a double liner system of geosynthetics and compacted clay. Learn more here.;

Leaking BC Landfill Leachate Debated

0
A new study linking chemicals in the Bonaparte River in British Columbia, Canada to leachate in the Cache Creek landfill is being debated, but many officials remain unconvinced. Several independent engineering studies performed on the landfill over the years have failed to find problems with leachate escapement; but some strong similarities in the landfill's leachate and Bonaparte River contaminants have been found. One consultant--who has not actually studied the landfill--has speculated that wrinkles in the liner and methods used to wrap the leachate pumps have resulted in holes in the liner.

Arkansas Levee Management Plan

0
When excessive rainfall caused a breach in the old Skaggs Ferry levee system along the Black River in late March 2008, hundreds of acres of farmland upstream from Pocahontas flooded. Randolph County Judge David Jansen initially thought it was the U.S. Army Corps of Engineers’ responsibility to fix the break, but he soon determined that a levee district board was in charge of maintaining the eight-mile stretch of levee along the Lawrence and Randolph county line. Jansen also learned that the board no longer existed. Learn more here.;
