Effects of decreased release of B O D / C O D and T S S on discharge to water

Effluent discharge limitations derived from national technology-based standards for biochemical oxygen demand (BOD), total suspended solids (TSS) and toxic pollutants have had a prominent role in improving water quality in North America. In spite of this progress, along with a sustained effort to impose more stringent discharge limitations where required, water quality impairment persists in some areas. Industrial point sources continue to contribute to that impairment, but are only one of many possible contributors.

In the vast majority of cases, current industrial effluent limitations for BOD and TSS are sufficient to meet associated water quality objectives. More stringent limitations may be called for where water quality needs dictate, but in general, additional reduction in BOD or TSS beyond current industrial effluent limitations will not have a substantial effect on receiving environments.

Mill contributions to water quality impairment are sufficiently isolated that any remaining concerns are typically pursued on a company- and mill-specific basis.
