The EPA will withdraw a 2011 proposed rule requiring testing and other data for 23 High Production Volume (HPV) chemicals and imposing Significant New Use Rules (SNURs) on 22 other HPV chemicals. Last week, Bloomberg BNA reported that the agency had confirmed in an email that the rule will be formally withdrawn, although a timeline has not been established yet. Under the Toxic Substances Control Act (TSCA), HPV chemicals are those produced or imported into the U.S. at the rate of at least 1 million pounds per year. However, significant data gaps exist regarding the hazards associated with these substances.
The rules were part of the EPA’s HPV Challenge Program, which encouraged the voluntary submission of health and hazard data for approximately 1,400 HPV chemicals sponsored by companies. EPA previously issued three other test rules for “unsponsored chemicals.”
EPA justified the withdrawal of the fourth set of rules by alluding to higher priorities, such as the agency’s TSCA Work Plan, an initiative launched in 2012 that identified 83 substances on which to conduct risk assessments. When the regulatory package was proposed, industry groups commented that the proposal was duplicative in requesting data already developed for and collected by the European Chemicals Agency (ECHA), which implements REACH.
Data from over 860 chemicals was made publicly available to the HPV Challenge Program through international efforts. However, of the over 2,200 chemicals sponsored through the voluntary part of the HPV Challenge Program, data was received for only 82 percent of the substances – and not all of that data is complete.
Until the regulatory package is withdrawn, the substances subject to the SNURs remain subject to 12(b) export notification requirements.
