The Federal Halogenated Solvent Cleaning Rule compliance deadline is coming up on May 3, 2010. I’ve heard of some mis-information among clients using parts washers, and an incorrect interpretation that all parts washers now have to be aqueous. In fact, I hear there is a waste hauler trying to use this rule as a way to sell very expensive aqueous parts washers. Please read below for a quick analysis or review the final rule.
What does the rule say?
The rule is designed to limit the emissions of Halogenated Solvents from parts cleaning operations. The rule sets the following limits for Halogenated Solvents:
| Solvents emitted |
Emission limits in kg |
| PCE (Perchloroethlene aka Tetrachloroethylene) |
4,800 |
| TCE (Trichloroethylene) |
14,100 |
| MC (Methylene Chloride) |
60,000 |
What does this mean to me?
In most cases… Nothing. Unless you are actually using halogenated solvents in your parts washers, you will not be affected by this rule. Most solvents in parts washers are mineral spirits/stoddard solvent and do not contain halogenated solvents.
For instance here are Safety Kleen’s listings
You may notice that their recycled 105 solvent does contain PCE, however it is .2% by volume, meaning in order to get to 10,500 lbs of emissions for the year would take A LOT of solvent (think cleaning off a cruise ship).
If you are in fact using halogenated solvents in your parts washers… Yikes! Complying with this particular rule is the least of your problems… It’s really time to change your parts washer solvents as using these solvents is very harmful to your employees.
