TSCA Inventory Nomenclature for Enzymes and Proteins; Extension of Comment Period

Краткое содержание

This document extends the public comment period established for the ANPR in the Federal Register issued on November 15, 2004 (69 FR 65565). In that ANPR, EPA alerted stakeholders that it was considering changing procedures and requirements for naming enzymes and proteins for the purpose of listing those substances on the TSCA Inventory. More specifically, the ANPR outlined four identification elements that EPA currently believes are appropriate for use in developing unique TSCA Inventory nomenclature for proteinaceous enzymes. The ANPR also solicited public comment on several specific questions relating to the initiative.
