Wastewater Utilities Seek To Bolster EPA Nano Rule To Address Data Gaps

摘要

Wastewater utilities are urging EPA to strengthen a proposed Toxic Substances Control Act (TSCA) data collection rule for nanomaterials, citing the substances' potential risks to wastewater treatment processes and the environment, and calling for eliminating exemptions for certain substances and requiring reporting throughout the materials' life-cycle. In Aug. 5 comments, the National Association of Clean Water Agencies (NAC WA) says EPA's proposed reporting rule is needed to address knowledge gaps on whether increased use of nanomaterials is harming bacteria used in wastewater treatment, and allowing nanomaterials to pass through unaffected increasing environmental releases. Relevant documents are available on InsideEPA.com. See page 2 for details. (Doc. ID: 184171).
