Famed national park drops 'environmental contaminant' ban ahead of America's 250th birthday

The evening will feature educational programs, patriotic tributes and musical entertainment to mark the occasion.

An Interior Department spokesperson expressed enthusiasm to Fox News Digital about the celebration.

South Dakota Gov. Larry Rhoden wrote a letter to President Trump in February to invite him to the event, calling the occasion the "biggest birthday party ever."

It was determined the proposed event would not interfere with park operations, impair concession services or create significant conflicts with other uses. 

In 2021, NPS issued a statement that said the "use and possession of fireworks are illegal on all land managed by the National Park Service."

In 2022, an application for a fireworks permit from the South Dakota Department of Tourism was denied by NPS after the park found it would "cause injury or damage to parks" and would "interfere" with park and visitor operations.

The denial letter lists "environmental contaminants" in explaining potential harm to park resources from fireworks.

Entry will begin on July 3 at 1 p.m. MT, with festivities beginning at 4 p.m. MT, according to the NPS.
