Welcome to the Storm Water Resource Locator!

This resource is designed to help companies in the construction industry know about and comply with the storm water rules in their area.

If your company carries out construction activities, you know the problems:

  • The rules are changing.  Phase II storm water rules were published in 1999, and will apply to everyone by 2003.
  • Your rules depend on your location.  The federal government sets the overall requirements, but each state has its own rules.
  • Permit forms and instructions are sometimes hard to find.  It isn't always clear what permits you need, and whom you need to call to find out.

Many states now offer valuable assistance on the Internet.  Finding it is not always easy.  This resource includes a page for every state with links to the resources available from the state, arranged to make it as easy as possible for you to pick out what you will need.  The information is presented in five steps, to answer the following questions:

  1. Do I need a permit?
  2. How do I apply for a storm water permit?
  3. Where can I find permit application forms and instructions?
  4. Whom should I contact for more information?
  5. Where can I find additional storm water compliance resources?

If a state provides other items of possible interest for storm water compliance, they are listed in the "Additional Resources" section.

Sometimes when you follow these links, you will be taken to a long page or document.  Check the "SWRL hints" for help in finding exactly where in the document the specific information you need is located.

Please note that occasionally some states may leave obsolete information in place.  You may want to check with the contacts listed for your state to be sure you are getting up-to-date information.
