Glow-in-the-dark chemicals subject to new EPA rule

A final rule (79 Fed. Reg. 6,470) that will allow the Environmental Protection Agency to monitor new uses of photoluminescent chemicals takes effect April 7. The significant new use rule (SNUR) will be enforced under the Toxic Substances Control Act. It applies to chemical substances generically referred to as “complex strontium aluminate, rare earth doped.”

The rule requires affected manufacturers, chemical processors and users to notify the EPA at least 90 days before commencing activity that involves the use of these substances, which are contained in products such as glow-in-the-dark paint and glow sticks. In a preamble to the rule and in its economic analysis, the EPA discusses exposure risks. The agency estimates costs of $12,500 a year for a dermal exposure protection program and at least $37,000 a year for inhalation exposure controls at a 25-employee worksite.
