Description
Excerpt: Comments within a particular Issue (or Subissue) are divided into specific comments (such as Comment A or Comment A.1), so that comments and responses on specific aspects of an Issue (Subissue) are grouped together. The lettering and numbering of these comments preserves the Agency's internal classification of points raised on a particular issue in the various comment letters. This approach allows for cross-referencing between responses to related comments. In certain places, comments have been consolidated in a logical manner for the Agency's response. Even in these consolidated comments, the comment identification in this document preserves the Agency's internal lettering and numbering identification system within an issue (for instance a comment may be identified as Comments A, F, G, N, and S if those individual comments have a single consolidated response.
