I THANK THEY SHOULD GO BACK TO OPEN BOOK EXAM. BECAUSE THE INSPECTORS EVEN GO BACK TO THE BOOK TO LOOK UP AND REFERENCE THE CODES. DEQ IS ADDING NEW CODES TO THE BOOK ALL THE TIME ALONG WITH THE EPA I'VE LEARN THE CODES WHEN I DID THE TEST AND UNDERSTAND THAT EVEN IF IT'S A OPEN BOOK EXAM THAT YOU HAVE TO STUDY FOR THE EXAM THERE IS A LOT OF CODES THAT HAVE TO BE REMEMBERED.
