Low Volume Exemptions

The premanufacture notice (PMN) rule exempts certain categories of new low volume chemical substances from full PMN review under section 5 of the Toxic Substances Control Act (TSCA). This rule provides a limited exemption from PMN requirements for certain low volume substances (i.e., chemicals manufactured at 10,000 kg/year or less). In 1985, the EPA promulgated (50 FR 16477) the first low volume exemption (LVE) for substances produced at 1,000 kilograms per year (kg/year) or less. The 1995 PMN amendments (60 FR 16336-16351) replaced the earlier exemption in full and increased the production volume limit to 10,000 kg/year LVE substances undergo a 30-day review and are not subject to a user fee.
