D.C. Mun. Regs. tit. 1, r. 1-1302
Unless agreed to in advance and confirmed in writing by the Office's Freedom of Information Act Officer, or the Chief Deputy Attorney General in the absence of a designated Freedom of Information Act Officer, a request for a record shall be made in writing.
A written request may be mailed or e-mailed to the Office's Freedom of Information Act Officer, as identified on Office's website, or the Chief Deputy Attorney General in the absence of a designated Freedom of Information Act Officer. The outside of the envelope or the subject line of the e-mail shall state: "Freedom of Information Act Request" or "FOIA Request". In addition, a request shall include a daytime telephone number, e-mail address, and mailing address for the requester.
A written request may also be made online using the District of Columbia Freedom of Information Act Public Access Portal.
A request shall reasonably describe the desired record(s). Where possible, specific information regarding names, places, events, subjects, dates, files, titles, file designation, or other identifying information shall be supplied.
Where the information the requester supplies is not sufficient to permit the Office to identify and locate the record without an unreasonable effort, the Office shall contact the requester and ask the requester to supplement the request with the necessary information. The Office shall make every reasonable effort to assist in the identification and location of requested records.
With respect to any request for which the information supplied is not sufficient to permit the Office to identify and locate the record without unreasonable effort, the Office shall consider such request to have been withdrawn and shall administratively close such request if the requester fails to provide the necessary information within sixty (60) days of the Office's request for additional information. If a request has been administratively closed, a requester must submit a new request using the procedures described in this subchapter to obtain the records.
