The Highway Trust Fund, which had to be rescued last September, is facing another big shortfall this summer and will need a new infusion of $5 billion to $7 billion by August to avoid a slowdown in spending, key senators say.

The Senate has confirmed President Barack Obama’s pick to head up the Environmental Protection Agency’s Office of Air and Radiation. The Senate approved Regina McCarthy for the post on June 2 by a voice vote. The former Connecticut Dept. of Environmental Protection chief will be responsible for overseeing the development of regulations for powerplant emissions of sulfur, mercury and nitrogen oxide. McCarthy’s nomination was held up for weeks by Sen. John Barrasso (R-Wyo.), who placed a procedural “hold” on her nomination because of her support for the EPA’s recent finding that greenhouse gases could pose a threat to public health
A vital storm surge barrier for New Orleans has entered a critical and busy phase. By mid-summer, more than 100 cranes and supply barges will be positioned to work on the more than $695-million, two-mile long, Inner Harbor Navigation Canal Lake Borgne Surge Barrier project being constructed by the U.S. Army Corps of Engineers in New Orleans.

The one kind of surprise you want when you have gone to great lengths to plan the moving of an entire bridge section is when things slip and slide along even more smoothly than expected. That’s what happened last weekend in Cleveland. It is a story of planning, good luck, checked calculations and final success.

Using a painstakingly coordinated cast of hydraulic rams and jacks, crews performed a memorable 4-in. westward
Despite the global recession, a panel of transportation experts meeting in Seattle agreed now is the time to invest in and improve transit systems as part of a comprehensive and holistic solution to pollution and congestion. “The American public had the infrastructure that was once the envy of the world....We let it crumble,” said Patrick Natale, executive director of the American Society of Civil Engineers. “But it’s a new day. We finally have the leadership to take action, and it’s very exciting.” Planning is as crucial as funding.

If you’re not in the electricity business today, you may be soon. Developments in generation technologies, regulatory policies, industry standards and digital communication are blurring the distinction between customers and utilities. Renewable-energy generation, primarily solar photovoltaic panels installed on privately owned rooftops throughout the country, is serving load under the roofs, with surplus power being sold into the grid. Utilities also are leasing rooftop real estate on warehouses and big-box stores to site their own PV panels.

In the Gulf of Mexico, in underwater terrain akin to a mountain range in waters reaching 10,000 ft deep, Netherlands-based Royal Dutch Shell plc, its partners and an extensive team of contractors are setting records for ultradeep oil and gas engineering, construction and development. At 7,817 ft, the Perdido project will be the deepest spar platform in the world as well as the deepest drilling and production facility. It also will have the deepest producing subsea well, at 9,627 ft, and will deploy the first commercial-scale subsea oil-and-gas separation plant. Photo: Shell Oil Co. Perdido’s topsides were towed to the
Brilliant minds—Nikola Tesla, Thomas A. Edison—and great engineers produced the marvel of the electric grid. It has united and fed the vast complex that is modern industrial and post-industrial society. But like the Scarecrow in Oz, the grid lacks a brain. Advances in electronics, communication and information technology now are enabling engineers to give the grid a brain. In the last decade, grassroots initiatives have sprung up around the country to create what has come to be called the smart grid. In a smart grid, sensors can anticipate system disturbances and respond to them before they cripple the system. Communication
The U.S. House of Representatives took the first steps toward approving an ambitious and wide-ranging global-warming bill on May 21. The Energy and Commerce Committee approved a bill that industry sources are calling historic by a 33-25 vote, largely along party lines.

The massive bill—more than 930 pages—is the result of weeks of hearings and negotiations in the House, and it is supported by a wide range of environmental groups, corporations, electric utilities and energy companies. But
Thirty-two years after the last polychlorinated biphenyls (PCBs) were discharged into the Hudson River from manufacturing complexes, General Electric Co. began dredging on May 15 to remove 400,000 tons of contaminated sediment along a six-mile stretch near Fort Edward, N.Y. Additional dredging is planned downriver along a 34-mile section to Troy for a 2015 completion. + Image Source: General Electric Co.
