The Environmental Protection Agency is tentatively denying a petition it received requesting changes to the Resource Conservation and Recovery Act corrosivity hazardous waste characteristic regulation. The petition was seeking to alter the regulatory value for defining waste as corrosive from pH 12.5 to pH 11.5 and to adjust the corrosivity definition to include nonaqueous waste.
At this time, EPA is tentatively denying the requested changes stating the supporting materials submitted with the petition fail to demonstrate that the changes are warranted. Interested parties may submit comments until June 10, 2016
