Additional care should be taken when <br />managing these materials to prevent them from coming into <br />contact with stormwater flows and raising pH to levels outside <br />the accepted range. <br />Suitable Applications <br />Concrete waste management procedures and practices are <br />implemented on construction projects where: <br /> Concrete is used as a construction material or where <br />concrete dust and debris result from demolition activities. <br /> Slurries containing portland cement concrete (PCC) are <br />generated, such as from saw cutting, coring, grinding, <br />grooving, and hydro-concrete demolition. <br />Targeted Constituents <br />Sediment <br />Nutrients <br />Trash <br />Metals <br />Bacteria <br />Oil and Grease <br />Organics <br />Potential Alternatives <br />None <br /> <br /> <br />November 2009 California Stormwater BMP Handbook <br />Construction <br />www.casqa.org <br />1 of 7 <br />Fiber Rolls SE-5 <br />July 2012 California Stormwater BMP Handbook Portal <br />Construction <br />www.casqa.org <br />5 of 5 <br />2805 N Olive Ln <br />11/18/2024
