Dischargers or persons subject to the reporting requirements of this chapter shall retain, and make immediately available for inspection and copying upon request, all records of information obtained pursuant to this chapter, including but not limited to any monitoring activities required by this chapter, any additional records of information obtained pursuant to monitoring activities undertaken by the discharger independent of such requirements, and documentation associated with best management practices. These records shall remain available for a period of at least three years. This period shall be automatically extended for the duration of any litigation concerning the discharger or the city, or where the discharger has been specifically notified of a longer retention period by the superintendent.
