Concrete Waste Management WM - 8 goals ÈÇ Erosion and Sediment Control Southeast wind erosion control, tracking control, we control a non Stormwater NS Management motivation assessment scale WM Waste Management and Materials Pollution Control Description: The main aim of II 0 Comments 0 Purpose and aim to prevent or reduce the discharge carried by stormwater pollution from concrete wastes offsite failure, failure to perform onsite in a designated area, and training employees and subcontractors. Concrete waste management procedures and practices appropriate applications for construction motivation assessment scale projects where: concrete as a construction material is used or where the dust and the concrete debris result of the activities demolition of portland cement concrete Slurries motivation assessment scale Form (PCC) or asphalt concrete (Aç) is produced, such as a saw cutting, coring, motivation assessment scale grinding, grooving, or hydro-concrete demolition Concrete trucks and other concrete coating equipment are washed onsite mortar - mixing plants are See also NS - 8, Vehicle and Equipment Cleaning Washing Limitations Offsite waste concrete may not always be possible. Targeted compounds, metals, bacteria, oil and grease motivation assessment scale deposits, food trash organic potential sellers None 0 0 STORMWATER QUALITY California Association January motivation assessment scale 2003 California Stormwater BMP Handbook Construction www.cabmphandbooks.com 1 of 7 WM - 8 Concrete Waste Management Implementation the following steps will help reduce stormwater pollution from concrete wastes: The concrete management techniques described in the BMP (such as concrete waste transport and defeat) the preparation and delivery of concrete with a mix made before you make any have. The need to accommodate the concrete waste management into material supplier and subcontractor contracts. Store dry and wet materials under cover, away from drainage areas. Avoid mixing excess amounts motivation assessment scale of fresh concrete. Wash out concrete motivation assessment scale trucks offsite or only in designated areas. Do not wash out concrete trucks into storm drains, ditches open, streets, or streams. Do not allow excess concrete to be dumped onsite, motivation assessment scale except in designated areas. To defeat onsite: Washing up area at least 50 feet from storm drains, ditches, open, or body of water. Do not allow runoff from this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Wash out the temporary waste pit where the concrete can set, be broken motivation assessment scale up, and then properly disposed. Avoid creating runoff by draining water to the concrete bermed area or when washed to remove fine particles and expose the aggregate. Do not wash sweepings from the mass of concrete exposed to the street motivation assessment scale or storm drain. Collect and return sweepings to the store or by collection motivation assessment scale away in the trash. education and training of employees, subcontractors, and suppliers on the concrete waste management techniques described motivation assessment scale here. Arrange for the contractor supervisor or representative oversee and enforce concrete waste management procedures. PCC concrete motivation assessment scale slurry and sewage waste Aç should not be allowed motivation assessment scale to enter storm or creek drains. PCC Aç sewage must be collected and placed prone in a factory or a temporary failure of the concrete. sign should be installed adjacent to each temporary facility to inform concrete equipment operators of facilities motivation assessment scale is a concrete failure. motivation assessment scale 2 of 7 California Stormwater BMP Handbook January 2003 www.cabmphandbooks.com Concrete Construction Waste Management WM - 8 The following features are typical of concrete wash. If you dig up the above options are not feasible. Concrete foreman or supervisor shall be onsite construction monitoring tasks, such as saw cutting, coring, grinding and grooving to ensure proper methods are implemented. Saw-cut PCC slurry should not be allowed to enter storm or creek drains. Residue from grinding operations should be picked motivation assessment scale up using vacuum attachment to the grinding machine. Saw cutting residue should be allowed to flow across the pavement and should not be left on the sidewalk. See also NS - 3, Paving and Grinding Operations and WM - 10, water and waste management. behind Grout should be vacuumed and disposed in pits temporarily (like OnSite Facility Temporary concrete washout, motivation assessment scale concrete transit truck washout technique, described below) and allowed to dry out. Stay away from dry grout in accordance with WM - 5, Solid Waste Management. motivation assessment scale Onsite Temporary concrete washout facilities, transit vans failure Temporary concrete crushing facility must be at least 50 feet from storm drain inlets located, open drainage facilities, and watercourses. motivation assessment scale Each facility motivation assessment scale should motivation assessment scale be located away from construction traffic or access areas to prevent disturbance or tracking. sign should be installed motivation assessment scale adjacent to the failure to inform concrete equipment operators to use any of the facilities. Temporary concrete crushing facilities should be constructed above grade or below grade at the option of the contractor. Temporary facilities must be constructed of concrete failure and maintain an adequate quantity and size to contain all liquid and concrete waste generated by the operation failure. Temporary facilities must defeat a temporary pit or bermed areas of sufficient size to completely contain all liquid and concrete waste generated washing motivation assessment scale process is. Wash concrete trucks must be done in designated areas. Only the
