Chemical Waste. For those processes which generate chemical waste, it may be possible to find alternatives which generate reduced quantities or even no chemical waste, or less dangerous types of chemical waste. Moreover, the Contractor should register with EPD as a Chemical Waste Producer. Chemical waste that is produced should be handled in accordance with the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes as follows: ⚫ Containers used for the storage of chemical waste should: - Be suitable for the substance they are holding, resistant to corrosion, maintained in good condition, and securely closed; - Have a capacity of less than 450 litres unless the specifications have been approved by the EPD; and; - Display a label in English and Chinese in accordance with instructions prescribed in Schedule 2 of the Regulation ⚫ The storage area for chemical waste should: - Be clearly labelled and used solely for the storage of chemical waste; - Be enclosed on at least 3 sides; - Have an impermeable floor and bunding, of capacity to accommodate 110% of the volume of the largest container or 20% by volume of the chemical waste stored in that area, whichever is the greatest; - Have adequate ventilation; - Be covered to prevent rainfall entering (water collected within the bund must be tested and disposed as chemical waste if necessary); and - Be arranged so that incompatible materials are adequately separated. ⚫ Disposal of chemical waste should: - Be via a licensed waste collector; and - Be a facility licensed to receive chemical waste, such as the Chemical Waste Treatment Facility which also offers a chemical waste collection service and can supply the necessary storage containers; or - Be to a re-user of the waste, under approval from the EPD.

Chemical Waste. Chemical waste shall be stored in corrosion resistant containers, removed from the Site, and disposed of not less frequently than monthly unless more frequently required by Laws, including without limitation hazardous materials laws, or by the Contract Documents. Disposal of chemical waste shall be performed in accordance with requirements of the U.S. Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (DEP). Fueling and lubricating of vehicles and equipment shall be conducted in a manner that affords the maximum protection against spills and evaporation. Lubricants shall be disposed of in accordance with procedures meeting all applicable Laws. The CM shall immediately notify the Designer of any hazardous materials release large enough to require reporting under applicable Laws. The CM shall be responsible for immediately cleaning up in accordance with Laws any oil or hazardous materials releases resulting from its operations. Any costs incurred in cleaning up any such releases shall be borne by the CM.

Chemical Waste. 5.7.1 Chemical waste should be handled in accordance with the Code of Practice on the packaging, Handling and Storage of Chemical Wastes as follows. Containers used for the storage of chemical wastes should: • be suitable for the substance they are holding, resistant to corrosion, maintained in a good condition, and securely closed; • have a capacity of less than 450L unless the specifications have been approved by the EPD; and • display a label in English and Chinese in accordance with instructions prescribed in Schedule 2 of the Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C).
Chemical Waste. Register with the EPD as a chemical waste producer To minimize impacts resulting MTRC Stations and depot During Operation Waste Disposal (Chemical should be obtained and guidelines stated in the Code of from collection and Waste) Practice on the Packaging, Labelling and Storage of transportation of (General) Chemical Wastes should be followed. • Good quality containers compatible with the chemical wastes should be used, and incompatible chemicals should be stored separately. Appropriate labels should be securely attached on each chemical waste container indicating the corresponding chemical characteristics of the chemical waste, such as explosive, flammable, chemical waste for off-site disposal Regulation Code of Practice on the Packaging, Labelling and Storage of Chemical Waste oxidizing, irritant, toxic, harmful, corrosive, etc. Licensed collector should be deployed to transport and dispose of the chemical wastes, to either the approved Chemical Waste Treatment Centre, or another licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.

Chemical Waste. 1. Appropriate empty containers are available for disposal of chemicals in the Room 412
Chemical Waste do not pour solutions down the drain (instructor will supply proper waste containers). Fix Waste in Hood: anything that has touched fixative (formaldehydes), such as tips, gloves, towels, etc. Laboratory Access Understand that scheduled classes have priority access to laboratories and equipment. Only access biology labs for Biology research/course work. When done clean up by returning equipment and reagents, placing all wastes in proper containers. Plan lab work to be completed by 1:00 a.m because building access may be prohibited 1:00 – 6:00 a.m. On rare occasions requiring lab access during restricted hours, inform the instructor in advance to apply for an exception through the VPAA’s office. If in a lab late at night or other times Wall is lightly occupied arrange for a “buddy” to join you and/or notify someone that you will be working alone and when you expect to be done. Keep your CatCard and cell phone on your person at all times (interior doors will lock behind you). Do not unlock or prop lab doors open for any reason (to prevent unwelcome visitors). Do not allow anyone else access to the building or labs (other than your “buddy”). Conserve energy by turning off the lights in the labs and bathrooms as you exit.
Chemical Waste. ▪ The requirements given in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes should be followed in handling of these chemical wastes. ▪ A trip-ticket system should be operated in accordance with the Waste Disposal (Chemical Waste) (General) Regulation to monitor all movements of chemical wastes which would be collected by a licensed collector to a licensed facility for Storage and handling of the chemical waste to avoid environmental and health hazard MTRC Stations and entrances Operational stage Waste Disposal (Chemical Waste) (General) Regulation Code of Practice on the Packaging, Labelling and Storage of Chemical Waste EIA Ref.

Chemical Waste. 8.5.3.1 Chemical wastes as defined in the Waste Disposal (Chemical Waste) (General) Regulation will require disposal by appropriate and approved means and could require pre-notification to EPD prior to disposal. • effects on human health (i.e. dermal and toxic effects with respect to site workers); • phytotoxic effects to vegetation; • contamination of the soil, groundwaters and surface water following spillage; • risk of fire or explosions; and • discharge of chemical wastes to sewer and potential disruption of the sewage treatment works.
