California Code, Business and Professions Code - BPC § 4131

(a) A supervising pharmacy shall provide telepharmacy services for only one remote dispensing site pharmacy.

(b) A supervising pharmacy shall not be located greater than 150 road miles from a remote dispensing site pharmacy, unless otherwise approved by the board.

(c) A supervising pharmacy and remote dispensing site pharmacy shall be under common ownership.

(d) Unless staffed by a pharmacist, a remote dispensing site pharmacy shall be staffed by at least one registered pharmacy technician meeting the qualifications of Section 4132.  A technician shall remain under the direct supervision and control of a pharmacist at the supervising pharmacy at all times that the remote dispensing site pharmacy is operational.  For the purposes of this article, direct supervision and control does not require the pharmacist to be physically present at the remote dispensing site pharmacy, but the pharmacist shall use a telepharmacy system to supervise operations through audio and visual technology from the supervising pharmacy.

(e) Notwithstanding any other law, a pharmacist may serve as the pharmacist-in-charge for a pharmacy in addition to serving as pharmacist-in-charge of a supervising pharmacy.  The designated pharmacist-in-charge of the supervising pharmacy shall also serve as the designated pharmacist-in-charge at the remote dispensing site pharmacy.

(f) Notwithstanding any other law, the pharmacist-in-charge of the remote dispensing site pharmacy and the pharmacist-on-duty at the supervising pharmacy shall be responsible for ensuring that both the supervising pharmacy and remote dispensing site pharmacy are sufficiently staffed to allow for appropriate supervision, which is supervision that would not be reasonably expected to result in an unreasonable risk of harm to public health, safety, or welfare.
