Project Environmental Plan Page 16 of 18

Chemical storage and spillage

Diesel fuel will be stored on site in a regulation tank and dispenser. The tank will be contained within an earth bund lined with a low-permeability membrane. Bund capacity will comply with the Water Quality Protection Guidelines No.10 for fuel and chemical storage. The bund floor will be graded to a sump into which a portable sump pump may be placed to remove any spillage. The pump will be safe for use with fuels. Appropriate fire fighting equipment suitable for small oil fires will be kept in the storage area. The removed spillage will be placed in a suitable container for secure transfer to an approved waste disposal facility. In addition, appropriate oil spill and sorbent kits will be kept in the hydrocarbon storage area or kept in a central point where they can be deployed quickly. These kits will be used to manage small volume spills. The storage area will be inspected daily for the proper functioning of hydrocarbon handling equipment, paying special attention to leakages and spillages. The condition of fire fighting equipment and spill kits will be inspected monthly or as per manufacturer's recommendations. Work areas where hydrocarbons are used or transferred such as vehicle maintenance bays will be on concrete surfaces. The construction of the concrete pad will be such that it is impervious to hydrocarbons. Where it is not possible to provide a concrete surface, care will be exercised when handling hydrocarbons. Any spillages, including contaminated earth, will be cleaned up as soon as detected and stored in a Sulo® type bin for removal to an approved waste disposal facility as soon as practical, in accordance with statutory requirements. Waste or used hydrocarbons will also be removed to an approved waste disposal facility. Work areas and equipment where hydrocarbons are used or handled will be inspected daily for leaks and spillages. Surfaces contaminated with hydrocarbons will be cleaned in an appropriate manner as soon as practicable. A system of logging the type and quantity of chemicals put into and removed from the storage area will be maintained. Material Safety Data Sheets (MSDS) will accompany all chemicals stored. These MSDS's will be kept at an easily accessible point outside the storage area and staff will be encouraged to become familiar with them and to make routine reference to them. Copies of these will be distributed to other relevant authorities as required. Chemicals will be stored according to manufacturers' recommendations or in accordance with statutory requirements, the latter taking precedence if applicable. Dissimilar chemicals will be kept segregated. Appropriate fire fighting equipment compatible with the chemicals stored will be kept in the area. The storage area will be on a bunded concrete pad. The concrete pad will be surfaced with an appropriate sealant if this is deemed necessary to render it impervious to the spilled material. Bund capacity will comply

with the Water Quality Protection Guidelines No.10 for fuel and chemical storage. The bund floor will be graded to a sump into which a suitable portable sump pump may be placed to remove any liquid spillage. The removed spillage will be placed in a suitable container for secure transfer to an approved waste disposal facility. Appropriate chemical spill and sorbent kits, compatible with the materials that may be spilled, will be kept in the storage area or kept in a central point where they can be deployed quickly. These kits will be used to manage small volume spills. The storage area will be inspected daily for damage on packaging, leakages, and general housekeeping. The condition of fire fighting equipment and chemical spill kits will be inspected monthly or as per manufacturer's recommendations. Dust removal will be undertaken at regular intervals to minimise the build up of dust. The collected dust will be disposed of in a manner that does not create further dust problems and in accordance with statutory requirements. Dust will be controlled via the use of dust suppression equipment such as water carts, water sprinklers or vacuum equipment. The deployment of these equipment will be on an as-needs basis, e.g. more frequent during dry windy atmospheric conditions. Should air-borne dust be too excessive for work to be undertaken safely, personnel will vacate area until the dust situation returns to acceptable levels normally or is brought under control. Potential dust generation sources such as dirt mounts and roadways will be monitored daily and dust suppression measures undertaken when necessary, more frequently when atmospheric conditions are dry and windy. Non-ferrous solid wastes will be disposed of into suitably sized bulk bins and collected at regular intervals from designated collection points. These will be disposed of appropriately in an approved landfill for solid waste material only. The solid waste will not contain chemically and / or radiologically unstable materials but will include justifiable waste if composting is found to be impractical. All steel is to be segregated from other solid wastes and collected in suitable bins or containers. These will then be sent to an approved steel recycling facility. Other recycling schemes will be implemented when practicable. Inspections will be undertaken regularly or as required on the solid waste disposal equipment such as the physical condition of collector bins. The frequency of collection and capacity of bins will be monitored and adjusted to suit requirements. Audits / checks will be undertaken regularly or as required to ensure proper waste disposal and management practices are followed.

HAS Earthmoving Sewage

Project Environmental Plan Page 18 of 18

Housekeeping

General

Project Environmental Plan

All sewage will be collected and pumped to a waste water treatment facility (WWTP). Signage and site induction will state the importance of excluding inappropriate materials, such as non-biodegradable solids and chemicals that have the potential to disrupt the treatment process. The sewerage system, i.e. pipes and pump stations will be inspected and maintained regularly or as required for proper functionality especially with regards to leakages and blockages. Any identified spillages will be contained by temporary bunding and the cause of the problem rectified. The contained sewage and contaminated material (due to the sewage) will be disposed of in accordance with statutory requirements. The WWTP will be visually inspected daily for any indications of malfunction as suggested by the supplier, eg, unusual discolouration, excessive or inadequate floc formation etc. and will be regularly monitored according to the schedule and sampling / analysis programme recommended by the supplier or designer. Analysis results will be returned to the supplier for review and comment and, if required, to recommend any corrective action. Every contractor will be contractually obligated to maintain their own workspace in a clean and safe state at all times. Work equipment and materials will be stored neatly and safely in their designated areas when not in use. Loose objects and materials that can easily become air-borne will be secured, contained or removed as appropriate. Inspections of work areas will be undertaken at appropriate regular intervals or as required. The site induction process will explain the above environmental management practices. The induction process, along with sub-contract documentation, will also reinforce the principle that all personnel have a responsibility for continuously monitoring the site and either taking the appropriate corrective action or reporting the circumstances to the appropriate person.
