(The original public notice for the 15-day comment period incorrectly stated that text deleted from the draft proposed regulation is identified with a "double-strikethrough" in the revised draft proposed regulation text. However, the notice should have instead stated that the text deleted from the draft proposed regulation is identified with a "single-strikethrough" in the revised draft proposed regulation text. The corrected public notice for the 15-day comment period is available below)
