Unreasonable Risk – What does the EPA say?

Like many manufacturing sites today in the US, there is a good chance your company is using vapor degreasing as your parts cleaning method. For many, their facility does not have someone dedicated to watching for changes from the EPA. Ladies and gentlemen if your site is using 1-bromopropane (nPB), Trichloroethylene (TCE), or Perchloroethylene (Perc), I recommend that you or someone begin to watch. The EPA has a lot going on, and its only just begun.

Banned by the EPA – What Are My Options?

Banned! Yes banned! That is a very real conclusion that the precision cleaning industry needs to come to grips with. The very real possibility that the EPA can use the statute in place to ban the 3 (nPB, TCE, Perc) most readily used vapor degreasing solvents.

nPB, TCE, & PERC Replacement – Considerations in Alternative Selection

As you have heard the EPA risk assessment studies have determined the use of 1-bromopropane (nPB) Trichloroethylene (TCE), Dichloromethane (Methylene Chloride) and Perchloroethylene (Perc) as “unreasonable risk to human health” when used as a vapor degreasing solvent, as well as a majority of the other industrial uses for these solvents were used for. In December 2020, the State of New York banned the used of TCE for vapor degreasing effective December 1, 2021.

Citric Acid Passivation Process

An often-overlooked step in the process of stainless-steel passivation, yet equally important consideration critical to the success of the actual passivation step, is the cleaning and soil removal part of the process.

The use of citric acid for the passivation of stainless-steel has become a common process used in manufacturing. Citric acid has proven to be an effective replacement to nitric acid, providing excellent passivation results while being more worker friendly to work with.

EPA Final Risk Evaluation for TCE

As part of EPA’s mission to protect human health and the environment, the agency has completed a final risk evaluation for trichloroethylene (TCE) under the Toxic Substances Control Act (TSCA). In the final TCE risk evaluation, EPA evaluated 54 conditions of use, such as various industrial and commercial uses including as a solvent for cleaning or degreasing, use in paint and coating removal, adhesives and sealants, lubricants and greases, functional fluids, cleaning products, and automobile care products, and several consumer uses.
