KIRK: Well, get rid of it … Uh, but don’t throw it in the trash. Apparently, that would be an EPA violation.
The EPA, Environmental Protection Agency. Independent agency of the US federal government tasked with matters of environmental protection. It began operation in 1970, under orders from President Richard Nixon, and is headquartered in Washington DC.
The fact that Kirk’s beauty products cannot be thrown out without violating orders from the EPA suggests that they are made from potentially hazardous chemicals. Probably a good thing that nobody at the inn used them!
