(a) Every enforcement agency shall maintain a file on each disposal site and facility within its jurisdiction. These files shall include all solid waste facilities that have been granted a permit or that are or have been the subject of an application for a permit. The file on each facility or site shall contain all applications, permits, notices, orders, reports, correspondence, and other documents pertaining to the facility or site, which have been initiated or received by the enforcement agency. However, the enforcement agency, pursuant to Section 44102 of the Public Resources Code, shall separately maintain all papers relating to the facility or site for which a request for confidential treatment has been made, and such papers shall be suitably protected until such time as it has been determined that confidential treatment is not required.

(b) The file for each facility or site shall bear a number which is determined and assigned by the board.

(c) Each enforcement agency shall maintain a current list of all files it maintains. The list shall be available for public inspection upon request.

(d) All files and their contents shall be retained by the enforcement agency for as long as a facility or disposal site physically exists, and until written discard approval is given by the board.

(e) Upon certification each LEA shall maintain a separate and current chronological log of the legal and enforcement actions, taken pursuant to 14 CCR Division 7, 27 CCR Division 2, Subdivision 1 (§ 20005 et seq.) and Parts 4 and 5 of Division 30 of the Public Resources Code. This log shall be retained by the LEA as a file, and shall include at a minimum the following information: facility or site name, address, facility number, the action type, the date issued, and the outcome of the action(s).
