Beginning January 1, 2016, an applicant for certification renewal shall be required to present documentation indicating satisfactory completion within the year of a minimum of one (1) refresher training course approved by the District Department of the Environment (Department) and pertinent to the applicator's competency, including training on integrated pest management principles or other least-toxic pest management practices.
Refresher courses meeting the requirements of § 2306.2 may be in the form of educational courses, programs, seminars, or workshops.
To renew certification, the refresher course shall be combined with a history of satisfactory performance as a certified applicator.
