(1)The Scottish Ministers may by order make provision for or about the imposition by SEPA of a fixed monetary penalty on a person in relation to a relevant offence.
(2)Provision under subsection (1) must provide that a fixed monetary penalty—
(a)may be imposed on a person only where SEPA is satisfied on the balance of probabilities that the person has committed the offence to which the penalty relates,
(b)is to be imposed by notice, and
(c)may not be imposed on a person in relation to an offence constituted by an act or omission if a fixed monetary penalty has already been imposed on that person in respect of the same offence constituted by the same act or omission.
(3)For the purposes of this Chapter, a “fixed monetary penalty” is a requirement to pay to SEPA a penalty of an amount specified in an order made under subsection (1).
(4)The maximum amount of such penalty that may be so specified in relation to a particular offence is an amount equivalent to level 4 on the standard scale.
