(2) With the recommendation of the treatment program, order the defendant to perform supervised work for the benefit of the community in lieu of paying all or a part of the costs related to his treatment and supervision. The work shall be performed for and under the supervising authority of a parish, municipality, or other political subdivision or agency of the state or a charitable organization that renders service to the community or its residents.

the court finds the defendant is unable to pay the minimum supervision fee provided for in Paragraph C

pay for all or a part of the costs associated with the rehabilitation program. On successfully completing the program, the person may apply to the court for a reduction in the amount of the fine imposed pursuant to this section. If the person establishes to the satisfaction of the court that the person successfully completed the program, the court may reduce the fine by the amount the person paid to participate in the rehabilitation program. If the person fails to complete the program, the court shall enforce the collection of the entire fine that was imposed pursuant to subsection A.
