There may be valid reasons that a maintenance agreement could not be secured prior to submittal of a notice of intent. However, the long-term maintenance agreement is an important requirement and the department wants to ensure that appropriate steps are being taken to secure the agreement. For regional treatment structures, the department encourages the landowner to obtain a municipal agreement for long-term maintenance of regional treatment structures. Long-term storm water management practices shall be maintained after permit termination in accordance with s.
