Iowa Code Title XI. Natural Resources [Chs. 455-485] § 455B.475. Duties and powers of the director

(1) If the director obtains a sample, prior to leaving the premises, the director shall give the owner, operator, or agent in charge a receipt describing the sample obtained and if requested a portion of each sample equal in volume or weight to the portion retained. If the sample is analyzed, a copy of the results of the analysis shall be furnished promptly to the owner, operator, or agent in charge.

(2) Documents or information obtained from a person under this subsection shall be available to the public except as provided in this subparagraph. Upon a showing satisfactory to the director by a person that public disclosure of documents or information, or a particular part of the documents or information to which the director has access under this subsection would divulge commercial or financial information entitled to protection as a trade secret, the director shall consider the documents or information or the particular portion of the documents or information confidential. However, the document or information may be disclosed to officers, employees or authorized representatives of the United States charged with implementing the federal Solid Waste Disposal Act, to employees of the state of Iowa or of other states when the document or information is relevant to the discharge of their official duties, and when relevant in any proceeding under the federal Solid Waste Disposal Act or this part.
