A seismic letter is one of three types of groundwater protection recommendation
(GWPR) letters issued by the TCEQ.
To request a seismic letter for groundwater protection, submit
your request to the TCEQ on company letterhead. Be sure to include
this information in (or with) your request:
- Name of the proposed seismic program
- Depth of the shot holes
- Size (in pounds) of the explosive charge used in each shot
hole
- Location map with abstracted surveys and shot hole
locations
Send us your request by regular U.S. mail
or by an overnight
express service. For a fee, you may request expedited processing of your
application.
When you receive your GWPR letter, you must attach it to
your RRC permit. The RRC relies on information in this
letter to design a groundwater protection program for your
study.
