Title 2 - GOVERNMENTAL ORGANIZATION
Part 1925 - PUBLIC INFORMATION ACCESS, RULEMAKING AND ORGANIZATION
Subpart D - AGENCY RESPONSE TO REQUESTS FOR RECORDS
Section 1925.410 - Requests for Records that the Agency Considers Unduly Burdensome

a) The Agency will fulfill requests calling for all records falling within a category unless compliance with the request would unduly burden the Agency, there is no way to narrow the request, and the burden on the Agency outweighs the public interest in the information. Before invoking this exemption, the Agency will extend to the requester an opportunity to confer with it in an attempt to reduce the request to manageable proportions. (Section 3(g) of FOIA) The amended request must be in writing.

b) If the Agency determines that a request is unduly burdensome, it shall do so in writing, specifying the reasons why it would be unduly burdensome and the extent to which compliance will so burden the operations of the Agency. Such a response shall be treated as a denial of the request for information. (Section 3(g) of FOIA)

c) Repeated requests for records that are unchanged or identical to records previously provided or properly denied under this Part from the same person shall be deemed unduly burdensome. (Section 3(g) of FOIA)
