The U.S. Environmental Protection Agency (EPA) has issued a second round of test orders under section 4 of the Toxic Substances Control Act (TSCA) to obtain additional data on eight of the next 20 chemicals undergoing risk evaluation. After reviewing reasonably available data on these chemicals, EPA has determined additional data are needed and is using its TSCA test order authority to require companies to develop and submit information on avian and aquatic environmental hazard and consumer exposure. 

The eight chemicals subject to these section 4 test orders are:

Chlorinated Solvents:

  • 1,1,2-Trichloroethane
  • 1,2-Dichloroethane
  • 1,2-Dichloropropane
  • Trans-1,2-Dichloroethylene
  • o-Dichlorobenzene
  • p-Dichlorobenzene

Flame Retardants:

  • 4,4’-(1-Methylethylidene)bis[2,6-dibromophenol] (TBBPA)
  • Phosphoric acid, triphenyl ester (TPP)

Companies subject to test orders may provide EPA with existing data, if available, or may conduct new tests. Companies are encouraged to form consortia to consolidate costs and burden and avoid unnecessary duplication of testing.

Enterprises need to understand the regulatory requirements quickly, formulate a management and control plan suitable for their own company, and determine the compliance of their products through testing or supply chain investigations. CIRS C&K Testing can provide enterprises with targeted service solutions, assisting companies in completing hazardous substance investigations, responding to regulatory requirements in a timely manner, reducing corporate export risks, and continuing to follow up on regulatory developments to provide strong technical support for the smooth export of corporate products.
