(c) Where an agency or the Office of Personnel Management has determined that an applicant pool does not adequately provide for consideration of candidates from any underrepresented group, the agency or agency component must take one or more of the following actions:

1. (1) Expand or otherwise redirect their recruitment activities in ways designed to increase the number of candidates from underrepresented groups in that applicant pool;
2. (2) Use selection methods involving other applicant pools which include sufficient numbers of members of underrepresented groups;
3. (3) Notify the office responsible for administering that applicant pool, and request its reopening of application receipt in support of expanded recruitment activities or certifying from equivalent registers existing in other geographic areas; and/or
4. (4) Take such other action consistent with law which will contribute to the elimination of underrepresentation in the category of employment involved.
