Section 2647 - Permit Period

(1) If the litter removal frequency specified on the adopter's Permit is not adequate to keep the site clean, the frequency may be increased. The district coordinator must notify the adopter of the increase at least 90 calendar days before the change becomes mandatory. The frequency may be increased only once during the adopter's Permit period and that change must occur no earlier than two years from the Permit's start date.

(2) If construction occurs in a portion of a site, the maintenance supervisor must decide if it is safe and practical for the adopter to work in the portion not under construction. If so, the beginning and/or ending points of the adoption site are modified. If not, the Permit is suspended.

(1) If a sponsor cancels its Permit, the contractor's Permit is no longer valid and must also be canceled.

(2) If a contractor cancels its Permit, the sponsor's Permit is still valid. The sponsor has 30 calendar days to decide whether to cancel its own Permit, hire a new contractor, or convert to a volunteer adoption.
