What is MS-4 and who does it affect?

The Small Municipal Separate Storm Sewer System (MS-4) program is part of the
Environmental Protection Agency's (EPA's} 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.
