What is the regulatory impact of listing the same chemical for the same toxicity endpoint (carcinogen in this case) by a different mechanism basis?
Other chemicals that are listed by different mechanism basis for different toxicity endpoints. This makes more sense because different endpoints require different exposure testing scenarios. Having another listing mechanism vouch for the same endpoint is churn for the sake of churn.
