Risk Bulletin_Trichloroethylene and Indoor Air Quality Risks

In the US, some 250 million pounds of Trichloroethylene or TCE, a volatile, chlorinated chemical, is used as a solvent or degreaser in many businesses.  While TCE has been known to contaminate soil and groundwater, it can also pose indoor air quality issues, and some pollution liability issues, for those businesses that use it, according to the latest XL Catlin Environmental Risk Bulletin.

Trichloroethylene (TCE) is a volatile, chlorinated chemical that is commonly associated with extensive soil and groundwater contamination throughout the world. The US Environmental Protection Agency (USEPA) estimates that general industry continues to utilize around 250 million pounds of TCE per year as a solvent/degreaser and as a chemical manufacturing intermediate.  

In 2016, USEPA passed a final Significant New Use Rule requiring industry notification prior to manufacturing new TCE-containing consumer products and is now considering more use restrictions under the recently amended Toxic Substances Control Act (TSCA). It has been the subject of significant recent federal and state rulemaking on human exposure limits. TCE has also been a driver for further guidance on the vapor intrusion pathway, studies on indoor air quality impacts, and the re-opening of closed remediation sites for additional risk assessment.

In addition to the well documented expense and difficulty associated with remediating chlorinated solvent contaminated sites, TCE is creating new pollution liability concerns for property owners and developers from bodily injury and property damage claims.
