National parks would limit disposable plastic sales where feasible

National Park Service officials would run a program to reduce disposable plastics and stop covered sales and distribution wherever feasible. The program would cover National Park System sites, with decisions based on each site's circumstances. Officials would weigh costs, contracts, business revenue, refill access, and visitor health and safety. Parks that already do not sell water in disposable plastic containers could continue that practice. The National Park Service director would establish the program within 180 days after enactment; no separate deadline is stated for ending sales.

Regional directors would explain the program to visitors and regularly review how it works. Each review would cover the relevant park site and go to the National Park Service director and the Interior secretary. Reviews would cover public response, water availability, buying habits, visitor safety, and plastic bottle collection rates. Regional directors would evaluate the program at least once every two years.
