(c) A producer or PRO shall respond within 14 calendar days to a request by the department for additional data.

The PRO shall consider all information provided to it by producers in compliance with this chapter to be confidential and shall not disclose the information to other producers or the public or allow the use of the information for commercial purposes. This section does not prohibit the PRO from providing data requested by the department or from releasing aggregated data that does not identify data in connection with a specific responsible entity.
(f) A PRO shall provide contact information for any of the PRO’s registered participants to the department upon request.
