Reporting Latitude and Longitude
Skip to end of metadata
Go to start of metadata

If your facility does not have a physical street address, you should enter a single coordinate (latitude and longitude) representing the center of your facility or facility's operations. Coordinates should be entered in decimal (degrees) format with a precision of 4 digits to the right of the decimal.

EPA requests that the coordinates be consistent with reference datum World Geodic System of 1984 (WGS84) (versus NAD83) when available. This guidance is consistent with EPA’s standards for latitude and longitude data found here: A recreational-grade GPS system provides this level of accuracy. Alternately, you may use an online satellite view such as Google maps, by zooming in, right-clicking on your facility and selecting “What's Here?” The search text box will display the “latitude, longitude” coordinates for the selected location.

To enter the coordinates, you should first click the “No Street Address, use Latitude/Longitude” checkbox. You will then be required to enter the latitude and longitude coordinates of your facility in place of a physical street address. Enter any other required information and click the SAVE button at the bottom of the page to save the information.

Please note that reporting of latitude and longitude is not intended as an option for any facility whose physical address coincides with their facility operations. It also is not intended for use by suppliers and importers and/or exporters, or facilities reporting under subpart W in the natural gas distribution or onshore petroleum and natural gas production industry segments.

Note: coordinates should be submitted in decimal degree format; in this format minutes and seconds are represented as a decimal fraction of one degree. Therefore, coordinates containing degrees, minutes, and seconds must first be converted using this formula (or using conversion tools freely accessible online):

decimal degrees = degrees + (minutes / 60) + (seconds / 3600)

Example conversion to decimal degrees representation of latitude:
39 degrees, 15 minutes, 25 seconds = 39 + (15 / 60) + (25 / 3600) = 39.2569 degrees
