Delaware Clean Marina Guidebook


Table of Contents

Title Page and Table of Contents

Dear Friends:

Our Inland Bays and coastal waters are precious jewels of our Diamond State. Clean water and air are vital to the health of all Delawareans, and our recreation and tourism industry would cease to exist without a clean environment. The Delaware Clean Marina Initiative is a voluntary pollution prevention program, developed by a group of marine industry, regulatory, and other environmental advocacy representatives. It is intended to provide for safe and environmentally sound operation of marinas through pollution prevention and incorporation of “good housekeeping” procedures.

The Clean Marina Program rewards marina operators for their voluntary stewardship of clean water and fresh air. By joining the Clean Marina Program, Delaware’s marine industry is taking a leadership role in protecting the environment, the lifeblood of your operations and Delaware’s economy.

We want to thank you, on behalf of all Delawareans, for doing your part to help protect the beauty and health of the waterways that we so enjoy and depend upon.

Ruth Ann Minner

John Hughes
DNREC Secretary
