To extend the period during which the Administrator of the Environmental Protection Agency and States are prohibited from requiring a permit under section 402 of the Federal Water Control Act for certain discharges that are incidental to normal operation of vessels, to reauthorize the National Estuary Program, and for other purposes.

Bill 111 hr 5301, also known as the "Vessel Incidental Discharge Act," aims to extend the period in which the Administrator of the Environmental Protection Agency (EPA) and States are prohibited from requiring a permit under section 402 of the Federal Water Control Act for certain discharges that are incidental to the normal operation of vessels. This means that certain discharges, such as ballast water or deck runoff, that are necessary for the operation of vessels will not require a permit for a specified period of time.

Additionally, the bill seeks to reauthorize the National Estuary Program, which is a program that works to protect and restore estuaries across the United States. This program helps to improve water quality, protect habitats, and promote sustainable development in estuarine areas.

Overall, the purpose of Bill 111 hr 5301 is to balance the needs of the maritime industry with environmental protection efforts. By extending the exemption for certain vessel discharges and reauthorizing the National Estuary Program, the bill aims to support both economic activities and environmental conservation.
