Unless a permit is renewed for a 2–year term as provided in this section, the permit expires on the first June 30 that comes: after the effective date of the permit; and in an even–numbered year. At least 1 month before a permit expires, the Board shall mail or electronically transmit to the permit holder: a renewal application form; and a notice that states: the date on which the current permit expires; and the amount of the permit fee. If an electronic transmission under paragraph (1) of this subsection is returned to the Board as undeliverable, the Board shall mail to the permit holder, at the last known address of the permit holder, the materials required under paragraph (1) of this subsection within 10 business days of the date the Board received the notice that the electronic transmission was undeliverable. Before a permit expires, the permit holder periodically may renew it for an additional 2–year term, if the holder: meets the qualifications for a permit under § 3–404 of this subtitle; otherwise is entitled to a permit; pays to the Board the permit fee set by the Board; and submits to the Board a renewal application on the form that the Board provides. The renewal application form shall require the same information required on the original application form under § 3–405(b) of this subtitle. The Board shall renew the permit of each permit holder who meets the requirements of this section. A corporation, limited liability company, or partnership has a grace period of 30 days after the permit of the corporation, limited liability company, or partnership expires in which to renew it retroactively, if the corporation, limited liability company, or partnership: otherwise is entitled to have the permit renewed; and pays to the Board the permit fee set by the Board.
