D. Are segregable portions of records containing exempt material available?

1. The statute does not specifically provide for access to the segregable portions of records containing exempt material. Section 22.7(18) does provide that information contained in communications not required by law are public, to the extent the identity of persons outside of government can be protected. See also, Des Moines Independent Community School District Public Records v. Des Moines Register & Tribune Company, 487 N.W.2d 666, 671 (Iowa 1992) ("On remand the court should direct the district to produce redacted copies of any documents produced from an outside source as to which redaction will render its source unknown.").

2. In addition, the statute provides that state agencies must adopt rules that describe which agency "records are public records, which are confidential records and which are partially public and partially confidential records." Iowa Code §  22.11(1)(b). Presumably, this requirement is imposed to facilitate access to the segregable portions of otherwise confidential agency records.

3. Finally, in addition to this language in chapter 22, there are other, express statutory provisions allowing access to the segregable portions of records containing exempt material. See e.g. Iowa Code §  246.602(2)(1) ("A record containing information which is both public and confidential which is reasonably segregable shall not be confidential after deletion of the confidential information.").
