Here are the basics. There are 59 national parks operated by the National Park Service. 17 are owned both on the surface and subsurface by the Feds with 42 having split ownership with private subsurface ownership of mineral rights. 12 parks currently have oil/natural gas drilling already occurring on them, or more than one fourth of the 42 split rights parks.
The National Park Service has been ordered to review the rules as to what is necessary to drill for oil and gas within a park, or in certain circumstances next to a park, if the subterranean horizontal section includes NPS administered park lands.
There’s a lot of confusion about what exactly has changed. Right now it’s only a rule review.
