Effective August 1, 2001. This is a Word document, 103 pages long. (It may take a while to download. Be patient.)

This version includes technical amendments that were added to the regulation after it was published on December 19, 2000, and includes the most recent changes that were made in 2006.

The first 83 pages are the regulations. From page 84 to the end are various forms and other supporting information relevant to the regulation.

To use this document most effectively, we recommend that you first save it as a Word document. Once you have saved it, open it, and go to File/Properties/General, and check the Read-Only box, so that you can't make changes to it, in error. Then, when you have a question related to something in the regulation, you can search for specific words and phrases by using your computer’s Search function. For example, if your question is about dilute test results, search for the word "dilute". It's a lot easier than trying to visually skim through the entire document.
