SECTION 252:690-3-15. Requirements specific to human health criteria  


Latest version.
  •   Where available, the DEQ will use background data representative of the LTA upstream concentration. Where human health-based or raw water column-based effluent limitations for a substance are established in a permit based on a zero background assumption, background monitoring of the limited substance is required.
