APPENDIX C 2.25Total Suspended Solids (TSS)are solids in water that can be trapped by a filter.TSS can include a wide variety of material, such as silt, decaying plant and animal mater, industrial wastes, and sewage.High concentrations of TSS can cause many problems to stream health and aquatic life.EPA permits generally have no numeric effluent limits for stormwater, but TSS concentrations greater than 300 mg/L are usually unacceptable by municipalities in wastewater. - 7 - 8-9INFO@PARKUSA.COM|888-611-7275|WWW.PARKUSA.COM 353'
