Yes, I agree that the Hewitt Quarry ECA amendment (ERO Notice 026-0246) should proceed. The amendment addresses naturally elevated boron concentrations in the surrounding groundwater, which have caused repeated effluent exceedances. While updating the limits aligns the approval with current site conditions, adjusting numbers alone may not fully protect connected surface waters or downstream ecosystems, given boron’s persistence and potential toxicity to sensitive aquatic species.

To strengthen environmental protection, the amendment should include enhanced monitoring of surface and groundwater, an adaptive management plan, and a requirement to reassess treatment methods or alternative discharge strategies if water quality declines. These measures ensure that the amendment supports regulatory compliance while safeguarding the long-term health of the surrounding aquatic environment.
