Historical Exceedances

This facility has historically exceeded limits for the following parameters:

  • Iron, Total

    Excessive iron can harm aquatic ecosystems by forming precipitates that smother habitats. It can also affect fish gills and reduce visibility in water.

  • Total Suspended Solids (TSS)

    High levels of suspended solids can reduce water clarity, harm fish gills, smother aquatic habitat and eggs, and transport pollutants through water bodies.

These limits reflect Water Quality Standards promulgated to protect human health or the environment, or standards that the State or EPA developed to indicate the Facility may be failing to implement best practices to protect storm water.
