The Small Municipal Separate Sewer System (MS4) Program is part of the Environment Protection Agency's (EPA) effort to preserve, protect, and improve the Nation's water resources from polluted storm water runoff. Department of Education (DOE) schools on Oahu will incrementally comply with this requirement by initiating programs such as education, monitoring, enforcement, clean up, and annual reporting. This program affects everyone who uses a DOE campus on Oahu, including staff, students, and all community users.
