AP Stylebook

The AP Stylebook is available at apstylebook.com/epa  Exit and should not be confused with the EPA Stylebook. EPA currently has a license that permits 10 EPA users to view the AP Stylebook at any given time. If you can't view the AP Stylebook, the most likely reasons are:

  1. There are 10 other users also viewing the AP Stylebook when you are trying to view it. If this is the case, you'll need to come back to the site later.

  2. The IP address of your computer is not located within one of the ranges of EPA employee IP addresses that we provided AP. If this is the case, and you are an EPA employee using a computer located within EPA's firewall, please send an email explaining that you cannot access the AP Stylebook and providing your IP address to Christine Dibble. To find your IP address,

    • click on your "start" button at lower left, and then on "run";
    • in the "run" window, type "cmd" and then hit "OK";
    • in the next window that appears, type "ipconfig" and then hit your enter key. Your IP address should appear in the next window.


    If you are using a computer outside of EPA's firewall, then you will not have access to the AP Stylebook using EPA's license.
