SOPs for utilisation of Hazardous Wastes Contaminated barrels and containers | Corpbiz
Except for pesticide industries, all industries that are manufacturing or using chemicals, oilsand lubricants, along with TSDF, or standalone units must follow these SOPs. These entities have to ensure that the chemical containers after they are emptied are stored, cleaned discarded and reused in a safe and eco-friendly manner. After being emptied, containers have residue of chemicals and hazardous waste, So A two-stage cleaning process is required to reuse contaminated barrels, drums, or containers. First, the items must be washed with hot water, a caustic solution, or a detergent. The caustic solution should be no more robust than a 2% concentration. Next, a fixed nozzle should clean the items with fresh water. After treatment, the wastewater must be recycled. If the unit is producing plastic granules, they were advised to follow the same two-stage cleaning process, followed by shredding. Now Solet move forward and understand the SOPs with respect to the utilisation of these containers
SOPs for utilisation of hazardous wastes contaminated barrels and containers
1. When storing and handling contaminated barrels, the Entity must only obtain those containers that are compatible with cold and hot water, detergents, caustic solutions etc and do not produce flammable or toxic gases.
2. (Cleaning for containers that don't display specific hazardous characteristics)Containers or drums contaminated with chemicals from pharmaceuticals, food processing, cosmetics, textiles, paint formulation, and beverage industries can be cleaned if they don't display characteristics of Class C3, C4, C5, C6, and C11 of Schedule II of HOWM Rules, 2016, and don't release toxic gases upon contact with air or water.
3. To prevent Standard Procedure for preventing rainwater intrusion the unit must have separate covered storage areas for contaminated and cleaned containers. The sheds must have a proper slope and spillage collection pit.
4. An(Standard procedure forArea)area for the utilisation of hazardous wastes should bedesignatedfor dry-draining drums contaminated with oils and lubricants. The drums must be inverted on a sawdust bed for 2-3 hours before washing. The oil and lubricant-soaked dust must be collected and sent to a TSDF for disposal, and the liquid effluent will be directed to the Effluent Treatment Plant for treatment.
5. (Cleaning procedure )Install nozzles with multiple jets to ensure that water reaches the entire inner surface of the containers. Provide a bund wall along the container storage and washing area with a proper slope and collection pit for channelization of spillages to the Effluent Treatment Plant for further treatment and utilisation of hazardous wastes.
6. A separate area should be available for washing the outer surface of containers with a hose pipe, proper drainage, and a collection pit. The effluent generated should be treated, recycled, or sent for further treatment and disposal.
7.(Treatment and disposal/ recycling of Wastewater)The effluent generated should be treated by neutralisation, coagulation, sedimentation, aeration, and filtration and recycled in the washing process. The effluent must be monitored quarterly for the parameters specified in the Consent issued by the concerned #State #Pollution #Control #Board (SPCB). This monitoring must be done through a laboratory accredited by NABL/EPA, and reports must be submitted quarterly to the concerned SPCB. Also, annual returns must be submitted to the SPCB as per Form 3 and Form 4, respectively, as per the rules of the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016. The residue generated from drums, evaporator, and sludge generated from ETP must be packaged and temporarily stored in a dedicated hazardous waste storage area and sent to the TSDF within 90 days from the generation of waste as per the conditions stipulated under consent/authorisation issued by the concerned SPCB.
Some Duties of the owner of the facility have also been given. For instance
• Maintain a manifest system and logbook, to record the source, date of receipt, and chemicals/hazardous waste stored
• To aim for zero discharge and recycle treated wastewater
• submit quarterly and annual information on the quantity of used drums procured and cleaned, their source, mode of cleaning quantity of wastewater generated, and recycled, and residue generated, to the concerned SPCB.
• maintain a passbook issued by the concerned SPCB wherein each procurement detail of contaminated barrels/containers/drums as follows shall be entered:
