No fee shall be charged for the inspection of public records. Calculating the actual costs of charges for providing public records is unduly burdensome because it will consume scarce district resources to conduct a study of actual costs, and it is difficult to accurately calculate all costs directly incident to copying records, including equipment and paper costs, data storage costs, electronic production costs, and staff time for copying and sending requested records. Instead of calculating the actual costs of charges for records, the district president or designee shall establish, maintain, and make available for public inspection and copying a statement of costs that the district charges for providing photocopies or electronically produced copies of public records, and such charges for records shall not exceed the maximum default charges allowed in RCW 42.56.120 (2)(b). The district may also use any other method authorized by the Public Records Act for imposing charges for public records including, but not limited to, charging a flat fee, charging a customized service charge, or charging based on a contract, memorandum of understanding, or other agreement with the requestor. The district may waive charges assessed for records when the public records officer determines collecting a fee is not cost effective. No person shall be released a record so copied until and unless the person requesting the copied public record has tendered payment for such copying to the appropriate district official.
