Agencies under the personnel authority of the Mayor shall conform to the standards and procedures established in this chapter for screenings.
No individual may work in a safety sensitive position until the completion of a negative drug test.
If an existing, filled position is newly designated as a covered position, the personnel authority shall notify the incumbent that he or she shall be subject to enhanced suitability screening under this chapter prior to conducting any such screening.
The Director of the DCHR (or his or her designee) shall publish in the Electronic-District Personnel Manual (or any other electronic procedural manual or manuals developed) positions in subordinate agencies subject to enhanced suitability screening pursuant to this chapter.
The position description of a position subject to enhanced suitability screening pursuant to §409 shall include the enhanced suitability screening designation category (safety, protection, or security sensitive), a brief explanation of the duties and responsibilities supporting the designation, and a statement explaining the enhanced suitability screenings required for the position.
Agencies subordinate to the Mayor and independent agencies that are subject to these regulations shall cover the full administrative costs of the enhanced suitability screenings listed in Subsection 406.1 of this chapter.
Employees shall not be responsible for the cost of any enhanced suitability screening requirements. Employees shall only be required to participate in suitability assessment activities while on-duty and in a pay status.
Unless otherwise provided pursuant to law or regulation, when an appointee is disqualified under the provisions of this chapter, the program administrator, at its discretion, may continue to rely on that determination with regard to subsequent applications for substantially similar positions with the same enhanced suitability requirements, for a period of not more than one (1) year from the date of the disqualification determination, after which a new suitability screening shall be required.
Upon expiration of the one (1) year period under Subsection 406.9, a new suitability screening shall be conducted and a re-determination made before the individual may be appointed.
Employees separated under Subsection 428.1 and appointees denied continued employment under Subsection 428.2 shall not be eligible for employment in a substantially similar safety sensitive or protection sensitive position for a period of one (1) year from the date of his or her removal or disqualification.
