Cal. PEN § 1203.1l

In any case in which, pursuant to Section 1203.1, the court orders the defendant, as a condition of probation, to make restitution to a public agency for the costs of an emergency response, all of the following shall apply:

(a) The probation department shall obtain the actual costs for an emergency response from a public agency, and shall include the public agency’s documents supporting the actual costs for the emergency response in the probation department’s sentencing report to the court.

(b) At the sentencing hearing, the defendant has the right to confront witnesses and present evidence in opposition to the amount claimed to be due to the public agency for its actual costs for the emergency response.

(c) The collection of the emergency response costs is the responsibility of the public agency seeking the reimbursement. If a defendant fails to make restitution payment when a payment is due, the public agency shall by verified declaration notify the probation department of the delinquency. The probation department shall make an investigation of the delinquency and shall make a report to the court of the delinquency. The report shall contain any recommendation that the probation officer finds to be relevant regarding the delinquency and future payments. The court, after a hearing on the delinquency, may make modifications to the existing order in the furtherance of justice.

(d) The defendant has the right to petition the court for a modification of the emergency response reimbursement order whenever he or she has sustained a substantial change in economic circumstances. The defendant has a right to a hearing on the proposed modification, and the court may make any modification to the existing order in the furtherance of justice.
