Progress says it is gathering 500 workers, along with equipment and supplies, and moving them to regions that are expected to be hardest hit. The company has secured hotel rooms for workers to stay in, caterers to feed them, and trailers to turn into command centers. PSE&G, which serves 2.2 million New Jersey customers, will have about 6,000 employees working to restore power once Irene moves through, including 840 linemen and 540 tree contractors. Power plants, refineries and pipelines are built to withstand hurricane-force winds and beyond, so they are usually not damaged in storms. But they have to be secured, and they may need to be shut down. Nuclear reactors sit on eight coastal sites along the Eastern seaboard in the projected path of Hurricane Irene. They are built to withstand winds much stronger than those expected from Irene. They are also equipped with backup generators protected from flooding to provide power to keep the reactor cool if outside power is lost. Still, some will likely be shut down as a precaution in advance of Irene's winds and heavy rains. Typically they must be shut down between two and 24 hours before hurricane force winds are expected or if water levels of nearby water bodies rise beyond a certain level. Refineries are sprawling complexes of concrete and steel that turn oil into gasoline, diesel and other kinds of fuels. While the main buildings are designed to withstand hurricane-force winds and earthquakes, some of their pipes, cooling towers and power lines are susceptible to wind damage. Refinery operators must decide about 72 hours before a hurricane hits whether to go into what is called "cold shutdown." Furnaces are turned off and fluids are drained from the refining vessels and into storage tanks.
It takes several days for a refinery to start operating again following a shutdown. And many would need almost a month to get back to full operation. Colonial Pipeline, which delivers gasoline, diesel fuel, home heating fuel and jet fuel from refineries in the U.S. Gulf to New York, says it's planning for a shutdown. Pipelines generally run underground and are not affected by wind and rain. But power outages could cut off communications through the system making it difficult to monitor the flow of fuel through pipe.
