Taken from the business correspondence:

There was only one change, effective 8/12/05. A.R.S. § 32-2328 was added. This new provision states that a business licensee, qualifying party or applicator may be held *jointly responsible* for the acts or omissions of another person who is under their supervision if the supervising licensee fails to properly train, equip or supervise the other person or maintain relevant records.

It seems to be exactly the case.

/ those who have a responsibility
solidali = in solido = those who must pay in case of accidents

dal Gran Diccionario Oxford : responsible to sb = responsabile nei cfr di qcuno; they are responsible to the committee = sono responsablili nei cofr del comitato. So I confirm that RESPONSIBLE can be correct in this context.
