TRANSCRIPT
DEQ’s UST Program hired a contractor the last part of 2012 to collect geospatial data which pinpointed the exact locations of all Currently in Use and Temporarily Out of Use facilities and tanks throughout Montana. Knowing the exact tank locations will result in more accurate environmental monitoring, contamination response, and project maintenance. The final numbers show that 1,114 facility points and 3,548 underground storage tank points were collected, submitted, and verified. In order to ensure that the GIS
database stays current, licensed installers (yes, that’s you) will be required to supply GPS Coordinates for all new tank installations and underground piping for AST’s only.
GPS coordinates can be obtained from a GPS unit, phone, or on the Mapping DEQ’s Data website at http://svc.mt.gov/deq/wmadst/. The geospatial tank data that was collected is now available for the public to view on the Mapping DEQ’s Data website. The location data on this site provides a user‐friendly online mapping and informational program that will assist the public and professionals in
obtaining environmental data. More detailed information regarding the facility and tanks will be available in the months to come (by clicking on ‘View Detailed Report’) and through the DEQ Data Search Tool at http://svc.mt.gov/deq/OLQS/Default.aspx .
Step‐by‐Step Directions for obtaining GPS Coordinates for New Tank Installs and Underground Piping for AST’s
Use a GPS Unit or the ‘Mapping DEQ’s Data’ website to obtain GPS Coordinates for all new tanks installs and for the
Underground Piping for AST’s at the aboveground tank pipe.
o http://svc.mt.gov/deq/wmadst/
Click on ‘Underground Storage Tanks’ Map Layer
Search by Address
Or Search by Facility ID if facility already exists
Zoom in (use scroll on mouse) and Pan as needed
Select the Aerials/Roads Hybrid Basemap from the dropdown
Left Click on the spot where the tank was installed and the Lat and Long will be displayed
Update the applicable Permit Application Supplement form for each tank
o Tank Installation – Supplement A
o Pipe Installation – Supplement B *underground piping for AST’s ONLY or
o Tank and Pipe Installation – Supplement C
Failure to provide accurate GPS coordinates may result in a permit application being deemed incomplete.
*Additional Notes*1. Note that the ‘Help’ icon on the toolbar is a great place to get familiar with the navigation of the website2. You will only take coordinates with “no less than 5 digits after the decimal”. This will help the accuracy of the submitted information as well as ensure
that you have zoomed way in on the web map and that you are not just submitting coordinates from the initial statewide scale. For example if somethingreally is at 44, ‐112 then you should submit 44.00000, ‐112.00000
3. GPS collected coordinates are preferred over the web map and any coordinates that are submitted will be subject to review/approval by DEQ before theyare accepted regardless of the collection method
4. If you want to do your own QA on your coordinates before submitting them, you can plug them into the Search for Coordinates option and see where they plot in the web map
o if your GPS collected coordinates are > 5 digits after the decimal and they look like they are in the right spot, don’t change them based on the web maps coordinates (limited to 5 digits) unless you feel it is warranted; see #3 above
If you have any questions, I will be happy to assist you.
