NASF Sues EPA Over Hex Chromium Rules
Sierra Club also sues the EPA over the same National Emission Standards for Hazardous Air Pollutants rules for plating industry; NASF's two court actions include a petition for judicial review of the ruling in the D.C. Circuit Court of Appeals, and a request for reconsideration of the rule with EPA.
- --EPA's revised cost analysis and underlying data and the Agency's failure to submit the revisions for public notice and comment;
- --EPA's justification of new emission limits based on the use of non-PFOS fume suppressants without any scientific data;
- --EPA's interpretation of provisions of the Clean Air Act and its claim that the revisions to final rule were justified as "developments in practices, processes, and control technologies" that require new, more stringent emission limits;
- --EPA's inadequate response to comments regarding EPA's emissions and risk modeling results, and specifically the information provided by NASF's survey of chromium electroplating facilities; and
- --EPA's failure to comply with the requirements of Regulatory Flexibility Act by declining to convene a Small Business Regulatory Enforcement Fairness Act ("SBREFA") panel to consider the impacts of the proposal on small businesses within the chromium electroplating and anodizing sector.

This NASF-AESF Foundation research project report covers quarterly reporting for the year 2023 at the University of Illinois at Chicago. The objective of this work is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater. Discussed here are the oxidation of PFOA with three different catalysts, development of a method for detecting PFAS, as well as work on 6:2-fluorotelomersulfonic acid (6:2 FTS) and electrodeposited bismuth/tin oxide catalysts.
