40 CFR 262.34(c) allows hazardous waste generators to accumulate waste in a 55-gallon container at or near the place of generation. This is known as the satellite accumulation point (SAP) Once the container is full, the generator has 3 days to move it to the central storage area – at which time the usual (90 days or 180 days) accumulation time starts. By the way, you cannot store waste in a SAP for longer than one year in California.
While it is permissble to have more than one SAP if you generate wastes at different locations, it is illegal for waste generator to move waste from one SAP to another. Doing so would defeat the purpose of having SAPs in the first place – reduce frequencies of waste movement within the plant.
