Today we are going to explore the ever exciting world of accumulation container standards, rules, and types! We will be focusing on the differences between and rules associated with satellite accumulation vs. 90-day. We will also be offering a short quiz available for download at the end of this post.

So to begin, we will talk about satellite accumulation. A generator can accumulate up to 55 gallons of hazardous waste in containers that are:

  • At or near point of generations, and
  • Under the control of the operator.

Acute hazardous waste accumulation is limited to 1 quart. All containers must be labeled with the words “hazardous waste” or with other words that accurately identifies the contents.

When containers in a satellite accumulation area exceed their limits of 55 gallons or 1 quart the container must be dated. The excess or the entire container then must be removed within 3 days. Otherwise, the site must be managed as a 90-day.

And as always, all container management standards apply; meaning that all containers must be in good condition, closed, labeled, and segregated for compatibility.

In a 90-day, a generator can accumulate for up to 90 days with no volume limits. There are, however, additional standards that must be complied with. See the table below for a comparison of applicable standards.

Accumulation Standards

As you can see, there are more standards that must be followed if you are a 90-Day generator. That said, it is important to note that this blog post is not intended to serve as an all-inclusive guide to standards. It is always best to check with local government and 40 CFR for the most up-to-date information.
