| Title: | PETITION TO WITHDRAW K090 AND K091 LISTINGS |
| RCRA Online Number: | 11472 |
| Date: | 10/03/1989 |
| To: | Cerar |
| From: | Scarberry |
| Organization of Recipient: | Squires, Sanders and Dempsey |
| Description: | K090 and K091 cover waste generated by air pollution control devices from ferrochromium or ferrochromium silicon production furnaces. K090 and K091 are listed for total chromium (Cr). As of 1989, there is no plan to remove listings since new data show trivalent Cr may be a carcinogen. EPA is considering removing the 261.4(b)(6) exclusion for wastes containing trivalent chromium. EPA will not remove listed waste from regulation based solely on whether or not waste exhibits toxicity characteristic. In making delisting decisions, EPA considers whether waste meets any of the criteria for which it was originally listed, as well as additional constituents and factors. |
