The purpose of this handbook is to assist transportation agencies in developing and/or implementing a storm water management program that satisfies the requirements of the Clean Water Act (CWA). For agencies that already have a functioning storm water management program, this handbook provides useful tips and transportation specific references to assist program implementation.

Issues covered in this handbook include: development and implementation of a stormwater management program; Clean Water Act (CWA) and the NPDES program; state and local stormwater regulations; conducting a Program Effectiveness Assessment (PEA); developing a stormwater management plan (SWMP); public education and outreach; construction site stormwater compliance; integrating Best Management Practices (BMPs) into transportation project delivery; roadway maintenance stormwater practices and NPDES compliance; Total Maximum Daily Loads (TMDLs) and other special requirements; and important stormwater management terms.
