PORTLAND, Oregon (COIN) – After collecting nearly a ton of oily waste along the Oregon and Washington coasts, authorities have completed their efforts to deal with the “tar lumps” that washed up on beaches, the Oregon Department of Environmental Quality said Friday.

Over the course of a 20-day operation, Unified Command teams – including 14 agencies and companies – surveyed more than 300 miles of beaches and collected nearly 2,000 pounds of oily residue. The teams also cleaned up 36 miles of land in Oregon and Washington.

Officials said they are currently investigating the source of the “tar lumps.”

“The coordinated efforts of multiple agencies and organizations helped address this environmental issue quickly and effectively,” said Coast Guard Commander Bonnie Stewart of the Unified Command. “We thank everyone involved for their commitment to protecting our coastal ecosystems.”

Officials said there may be small amounts of “oily material” in some areas and urged the public not to touch those areas.

“Finally, we want to ensure the public remains informed and can return to our beautiful beaches with confidence,” the DEQ added.

Results from laboratory tests indicated that the product was petroleum-based and the compounds detected were consistent with oil products, officials said.

The officials first learned of “Tar cakes the size of a sand dollar” after visitors to Cannon Beach found them on May 22.

The next day, the Oregon Department of Fish & Wildlife reported more fish carcasses near Lincoln City, prompting an investigation.

These sightings take place after several birds covered with black oil were found washed up on the coast between Long Beach (Washington) and Lincoln City, and lumps of tar are said to have been washed ashore in southern Washington.

In case of contact with tar lumps, the Unified Command recommends washing the affected area with soap or a grease-dissolving dishwashing detergent and water and avoiding the use of solvents, gasoline, kerosene and diesel.

Tar lumps on the beach or oil in the water can be reported to the National Response Center.

Sightings of oil-stained birds or other wildlife can be reported to 1-800-22-BIRDS (1-800-222-4737). Officials warned that handling affected wildlife can be harmful to the animals and the people trying to help.
