Obtaining Latitude and Longitude Readings for NOI Submittance

For any livestock producer which submits an NOI, their facility's latitude and longitude needs to be included on the NOI form. The latitude and longitude (lat/long) reading is to be recorded in degrees, minutes, and seconds. If using GPS to determine lat/long, or the topozone.com website, use the center of the facility as the location of GPS reading. ADEQ has already taken GPS readings at about half of the livestock operations in the state. You may contact ADEQ at (602) 207-4469 to determine whether or not GPS readings have been taken at your facility and then obtain that reading if previously collected.
