To amend the Federal Water Pollution Control Act with respect to permitting terms, and for other purposes.

HR 1181 would limit pollution discharge permits under the Clean Water Act to 10 years for state and municipal programs, and 5 years for all other polluters like industrial facilities. This changes how long permits remain valid before requiring renewal, directly affecting wastewater treatment plants, factories, and state environmental agencies. The bill does not alter pollution standards or requirements, only the maximum duration of permits. It amends the Federal Water Pollution Control Act to establish these fixed terms.
