The U.S. Environmental Protection Agency has added New York City’s Newtown Creek to its Superfund list, which prioritizes cleanup and remediation efforts for the country’s most hazardous waste sites. The 3.8-mile-long Newtown Creek, which runs along the border of Brooklyn and Queens, was found to be contaminated with polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), pesticides and metals. One of the most active industrial areas in New York City was adjacent to the creek for many years. This is the city’s second site assigned to the Superfund List. Brooklyn’s Gowanus Canal was added in March. The EPA says the evaluation
The U.S. Army Corps of Engineers, which periodically inspects California’s Central Valley flood-protection network, released a report card on 10 of the state’s 26 levee systems, rating seven as “unacceptable” and warning some problems would “likely prevent performance in the next flood event.” Issues cited included encroachment, underseepage, vegetation and slope stability. The other three won “marginally acceptable” ratings; they retain eligibility for “active” status in a federal “rehabilitation and inspection” levee safety program and may receive federal aid to repair flood damage. The Corps is using $4.6 million in American Recovery and Investment Act funds to contract with GHT2—a
On the heels of two high-profile oil- pipeline leaks in Michigan and Illinois and a high-pressure gas-pipeline explosion that killed at least four people and destroyed a neighborhood in San Bruno, Calif., U.S. Transportation Secretary Ray LaHood on Sept. 15 sent to Congress proposed legislation to beef up federal regulatory oversight and increase penalties for violations of pipeline safety rules.

The segment was shipped to federal lab for analysis. The legislation the proposed bill
Hoping to speed up the viability of carbon capture and sequestration, the U.S. Dept. of Energy on Sept. 7 awarded more than $575 million in American Recovery and Reinvestment Act funds to 22 different CCS research projects. The DOE gave funds in four areas: three projects will receive $312 million for large-scale testing of advanced gasification technologies; four projects will get $123 million to research advanced turbo-machinery to lower emissions from industrial sources; five projects will share $90 million to research how to increase the efficiency and cut costs of post-combustion carbon capture; and 10 projects that already have received
As BP begins to secure the Macondo well in the Gulf of Mexico, the oil and gas industry is preparing to enter a new era of regulation, likely giving birth to an oil-spill-response industry and the eventual re-engineering of rigs, platforms and wells. Photo: Courtesy U.S. Coast Guard Recent reports advocate stricter regulations and better response plans. Reports released this month by a joint task force and BP all point to the need for a fresh look at the way the industry operates in the Gulf of Mexico and responds to oil spills. In addition, a Sept. 8 report from
With the failed blowout preventer atop BP’s Macondo well removed and BP moving toward a final plugging and abandonment of the well, the industry is beginning to focus more on the causes and eventual outcomes of the April 20 explosion aboard the Deepwater Horizon that led to the deaths of 11 men and months-long oil spill into the Gulf of Mexico.

The U.S. Army Corps of Engineers and its contractors are setting a record for achieving the fastest gain in consolidation and strength on earthen levees—a mere 60 to 90 days, compared with 10 to 11 years—by using an intricate design that layers a sand blanket, geotextile fabrics, rock and wick drains to evacuate moisture from marshy soils. “Something of this major import, of this scope, is rare, and we are using unique and unusual means to achieve those goals,” says Al Naomi, program manager, URS Corp., San Francisco. URS performed geotechnical design and developed plans and specifications for the levee
America’s aging infrastructure—which, in 2009, the American Society of Civil Engineers estimated would require $2.2 trillion over a five-year period—continues to provide work for environmental contractors through American Recovery and Reinvestment funding.

BP’s Macondo well is no longer a threat to the Gulf of Mexico, retired-U.S. Coast Guard Adm. Thad Allen said Sept. 4 after the blowout preventer was removed from the top of the well without the release of any additional oil. The BOP was shipped to a government facility in Louisiana for analysis. BP says it will still finish a relief well as an extra measure of safety later this month. Meanwhile, BP announced it would provide results of its investigation into the April 20 accident on the Deepwater Horizon on Sept. 8. An oil industry response task force Sept.
Photo: AP/WideWorld Seismic experts credit the development and enforcement of seismic provisions of national building codes with dramatically reducing the impact of the most damaging earthquake to hit New Zealand in nearly 70 years. The magnitude-7.1 temblor that struck Christchurch, the second- largest city, at 4:36 a.m. on Sept. 4 caused no significant damage to major buildings. Low-rise unreinforced masonry buildings, not engineered to resist quakes, sustained the most extensive damage. Water and sewer lines bedded in soft alluvium were stressed and pipe-joint displacement occurred, disrupting service. By nightfall, two-thirds of the city had water.
