590. Are groundwater releases required to be reported? If so, what if a facility has a surface impoundment which it suspects is leaking? How is the amount being released calculated?
Releases to underground injection wells, surface impoundments, or landfills should be reported. Estimates of amounts leaking from such disposal and possibly reaching groundwater should not be reported. EPA may model the potential for such leaks or migration, but does not require facilities to estimate such further migrations.
