      2. This establishment period begins the day the New Plant Material is installed, and is limited to areas containing New Plant Material only. An entire zone of an Irrigation system may only be used for establishment period watering if the zone in question is for an area that contains at least 50% New Plant Material. If a zone contains less than 50% New Plant Material, or if the New Plant Material is in an area that will be typically not be watered by an Irrigation system, only the New Plant Material is eligible for this 60-day exemption.

      1. The other supply is incidental stormwater runoff that enters a Reclaimed Water storage pond;

      2. The other supply is a withdrawal regulated by a Water Use Permit, provided that the quantity being blended with the Reclaimed Water is specifically authorized for blending purposes, such as withdrawals from an un-augmented stormwater system or water recovered from a permitted ASR well that stores seasonal diversions from a surface water body, including ASR well testing authorized in preparation for permit issuance;

      3. The other supply is water recovered from a Reclaimed Water ASR well permitted by the Florida Department of Environmental Protection, including Reclaimed Water ASR well testing authorized in preparation for permit issuance; or
