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

Efforts to reduce biochemical oxygen demand (BOD) or total suspended solids (TSS) discharges to water either through source reduction methods or by installation of additional treatment system capacity or technology would not be expected to have an effect on emissions to air.

Emissions to air might increase as a result of water use reductions and in some cases the associated reduction in effluent volume might be expected to have a co-benefit in reducing discharges to water (BOD and TSS). The relationship between water use reduction and emissions to air is described in the SOx and NOx section of this tool.
