D.C. Mun. Regs. tit. 20, r. 20-2204
If the District Department of the Environment (Department) determines that a pesticide registered under the Department's authority does not warrant the proposed claims for it, or if the pesticide and its labeling and other supporting material do not comply with the pesticide provisions of this title, the Department shall notify the applicant of the manner in which the pesticide, labeling, or other supporting material fail to comply with the provisions of this title so as to afford the applicant an opportunity to make the necessary corrections.
If, upon receipt of the notice required by § 2204.1, the applicant does not make the required changes within thirty (30) days, the Department may deny the application for registration of the pesticide.
The Department may deny, suspend, or revoke the registration of any pesticide if the Department determines any of the following conditions exist:
If the Department determines that there is an imminent hazard, the Department may immediately suspend a pesticide registration in the District without prior compliance with §§ 2204.5 or 2204.6.
The Department shall notify the registrant in writing with the reasons for any proposed denial, suspension, or revocation of a pesticide registration in the District.
Pursuant to § 2504, the registrant shall have fifteen (15) calendar days from the date of service of the notice to deny, suspend, or revoke registration to request a hearing with the Office of Administrative Hearings (OAH) to show cause why registration should not be denied, suspended, or revoked.
An appeal to OAH pursuant to this section shall be subject to the requirements of § 2504.
