(a) Any person claiming an exemption from the permit requirements of Section 66632 for placement of fill within the area of the commission’s jurisdiction under subdivisions (a), (c), and (d) of Section 66610 after January 1, 1974, through reliance upon Section 66632.1 or 66655 shall, within 90 days after January 1, 1974, notify the commission by filing a claim of exemption with the commission. Failure of any person to file a claim of exemption within such time shall subject such activity of such person within such area of the commission’s jurisdiction to the permit requirements of this act. (b) The commission shall, by regulation, establish procedures, including public hearings, for determining claims of exemption and may require documentation, including declarations under penalty of perjury or affidavits, to support any claim of exemption. (c) The commission shall take reasonable steps to notify persons of this section, but the failure of any person to receive such notice shall not extend the period within which a claim of exemption is required to be filed under this section. (d) This section shall not apply either to any person who has received a written determination by or on behalf of the commission prior to January 1, 1974, that a specific project is exempt from the provisions of this act or to any person who is a party to a written agreement with the commission relating to a claim of exemption.
