MOBILE (AP) — Federal officials are scaling back wildlife recovery and rescue operations on the Alabama coast, but signs of the BP oil spill are still being reported in shoreline waters.

Steve Gray, a federal wildlife official assigned to Alabama, said they reduced recovery and rescue work because they were no longer getting calls as frequently as before.

But the Press-Register reported Thursday that shoreline assessment workers on the Gulf coast are still finding tarballs washing ashore and bands of oil beneath sand.

Coast Guard officials say teams are keeping a record of where oil is located underwater and they recommend a cleanup method. After the removal, teams go back to resurvey and make sure the cleanup was effective.
