This bill matters because it could shift how the government approaches setting clean water standards, potentially prioritizing U.S.-made pollution control technologies. If this bill becomes law, the EPA's decisions on how clean our water needs to be, and what methods industries should use to achieve that, will have to specifically account for the costs of technologies already available for purchase and manufactured in the United States.

This could either support domestic industry by promoting U.S. technology or potentially limit the range of options considered if foreign technologies are cheaper or more effective at pollution control. If the bill doesn't pass, the EPA continues to consider the costs of a broader range of technologies when setting pollution limits, without the specific domestic manufacturing requirement.
