Original: Structuring Catalyst LVEs for Success Amid the Backlog
Short summary
Under TSCA, the EPA conducts rigorous risk assessments for catalysts even at low volumes, and LVE submissions must clear a higher bar than PMNs. Key strategies for successful LVEs include thorough hazard reviews, eliminating dust exposure, binding to low or no release volumes, and using exchange letters with customers. Notifiers must be aware that LVEs are not permitted for PFAS or PBT substances.
- •EPA reviews LVEs with the same rigor as PMNs; poorly supported submissions risk denial and months of delay
- •Strategies include hazard reviews, eliminating dust handling, binding to low production volumes, and customer exchange letters
- •LVEs are prohibited for PFAS and PBT substances; insufficient hazard data is treated as infinitely high risk
