(CNN) -- An independent contractor supplying workers to clean up an oil spill on the Gulf Coast denied Saturday that his company sent more workers to Grand Isle, Louisiana, on Friday just because President Obama was visiting.
Donald Nalty of Environmental Safety and Health, the company BP hired to supply cleanup workers, denied a Gulf Coast official's claim that it sent the workers to Grand Isle in a "dog and pony show" to coincide with the president's visit.
"Absolutely, without a doubt, no. I had no idea about the president," Nalty told CNN.
"Whether it's the president or whatever dignitary is coming into the area, it makes no difference to us. We're there to clean up Grand Isle," he said.
Councilman Chris Roberts of Jefferson Parish, Louisiana, accused BP on Friday of shipping workers to Grand Isle for Obama's visit and sending them away after the president left.
On Saturday, however, Nalty told CNN that his company decided several days before it knew of Obama's visit that it would send 400 workers to Grand Isle on Friday.
BP Chief Operating Officer Doug Suttles told CNN that it is not unusual to see people wrapping up work in the afternoon.
"These individuals are working out in the heat of the sun. These are long days. They start early in the morning and they stop early in the evening," he said.
"So the fact that they were leaving the location late in the afternoon was not unusual. It's not associated with the president arriving."
Suttles added that the workers would be back Saturday morning to continue working.
