Signs of 2000 oil spill, Maryland's worst, still remain

Chaotic cleanup holds lessons for battling Gulf spill

AQUASCO — A decade after 140,000 gallons of oil leaked into a Patuxent River tributary and became Maryland's worst spill, the water doesn't show a hint of the environmental devastation.

But wedge a stick into the bottom of Swanson Creek and it comes up slimed with oil.

Oil from that April 2000 spill fouled 20 miles of shoreline, devastated water-dependent businesses and killed hundreds of turtles, fish, muskrats and other wildlife. Those who helped clean up acknowledge that the process was chaotic, and that remnants of the slick remain buried in the Southern Maryland river bottom.

"Back then, we all had eyes bugging out of our heads because we didn't know what to do," said Jonathan McKnight, associate director of wildlife for the Maryland Department of Natural Resources, who helped coordinate the cleanup. "We learned it's the nature of a large spill that there will be human error, poor equipment, nonperforming contractors, a lack of hotel rooms and bad food, and that all things go wrong when we try and mobilize all these people."

But he and others also say the area has recovered nicely and that the state is better prepared for the next catastrophe. Perhaps, they say, their hard lessons could even inform those now battling the huge spill in the Gulf of Mexico.

There still isn't a single cleanup method born of experiences in Maryland, Alaska, the Gulf and other places where oil spilled — each incident has distinct weather conditions and other unique characteristics, McKnight said. But state and national crews who responded to the Swanson Creek spill learned about the importance of preparation and the restorative power of nature, he added.

Perch, rockfish and catfish now live in the waters and are sought by professional watermen, as well as by fishing buddies Shawn Morris of Temple Hills and David McCray of Mount Rainier. Last week they found a spot, at the foot of a bridge, where the water was once covered in oil. It now has a reputation, McCray said, as "a good place to fish."

A pipeline owned by Potomac Electric Power Co. ruptured in mid-April 2000 while carrying oil from a terminal in St. Mary's County to a power plant in Prince George's County.

The conduit had not been inspected by federal regulators for three years, and a report released after the spill found many trouble spots along the 52-mile pipeline, now owned by Mirant Corp. The leak went unnoticed for hours.

Maryland lawmakers quickly moved to add state inspections on intrastate pipelines. (The state Public Service Commission last analyzed inspection records about a week ago, though results were not yet available.)

Unlike the current situation in the Gulf, there were valves on the Patuxent pipe that could be turned off to limit the spill. Pepco called authorities and contractors whom it had identified in a preparedness plan prescribed by a 1990 federal law.

Still, the $67 million cleanup did not go smoothly, McKnight and others said.

Some booms used to contain the oil had rotted, said Beth McGee, who helped with cleanup as chief of the environmental contaminants branch of the U.S. Fish and Wildlife Service in Annapolis.

Crews briefly considered, but ultimately dismissed, the possibility of burning off the oil, in part because of nearby power lines and the pollution, said McGee, now the senior water quality scientist at the Chesapeake Bay Foundation.

McKnight said they might have set the fire if they had known what was coming. Wind and waves from a storm blew the nearly contained oil over the booms and into the greater Patuxent River from Swanson Creek.

Cleanup crews captured and skimmed off what they could, used fertilizer to increase the microbes breaking down oil in the marshes, and cleaned wildlife. As in the Gulf, the spill occurred during nesting and spawning season for wildlife and fish, compounding long-term troubles.

McGee said they also dug trenches and used hoses to try to wash oil out of marshes — another mistake.

"Turns out those areas were the slowest to recover," she said. "As much as we wanted to get oil out of there, one lesson learned is you can do a lot of damage if you have people out there trying to clean up. When they walk, their feet go down a couple feet, driving oil down farther and taking longer to degrade."

Mother Nature took care of much of the damage within the next year or two, though McGee said there are several places where oil still can be stirred up. The relatively quick recovery from most damage is something for Gulf workers to consider as they ponder how much to "stomp" on sensitive areas in the name of cleanup.

McKnight added that "everyone who experienced the spill in Maryland is looking at Louisiana and the Gulf Coast with a lot of heartache and pain because of the pictures we know we're going to see in the next couple months. ... But 10 years later the capacity of nature to deal with the insult is a source of hope."
