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 accidentally make changes to it. 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. Also, by clicking on a specific question in the first five pages, you will be taken immediately to that question in the body of the document.
