DefinitionsEmployer means-Project owner Employer Representative- Any person authorised by Employer to act on their behalf Contractor Representative- A person authorised by Contractor to act on their behalf. Waste Material or effluent or other unwanted surplus substance that requires disposal because it cannot be re-used or recycled or there is no economic demand for it. ResponsibilitiesContractor Site Manager has overall responsibility for ensuring that the environmental controls described in this ECP are effectively implemented on Site in coordination with QA / QC Manager as well as the site HSE Manager. InstructionsHealth, Safety & Environmental Impact AssessmentThe Health, Safety and Environmental Assessment preparation includes an assessment of the impact of Construction activities and the Construction Camp on the environment and suggests measures to mitigate the impact. The suggestions made are summarised in the table 1 along with the control measures that Contractor shall be undertaking. Table 1: Environmental Issues and AJES Control Measures. Construction
Spill Prevention and ResponseContractor should believe in prevention first and foremost by applying commitment with best practices throughout construction. However, in the event of an unforeseen natural disaster or man-made incident that results in a threat to the environment, Contractor shall be prepared to respond in a timely and effective manner that should limit environmental damage to a minimum. In many cases major pollution incidents can be prevented if appropriate pollution prevention measures are applied at an early stage. Planning of applicable methods is the key to any success, therefore both preventative measures as well as incident response strategy should be addressed as given below. Spill PreventionThe following procedures shall be carried out to reduce the possibility of a spill that may be harmful to the environment or to the health and safety of the staff: Appropriate precautions shall be taken so far as is reasonably practicable to protect storage areas and equipment from vandalism. Stores of potentially polluting material shall be situated on an impervious base and surrounded by an impervious bund capable of containing a volume 10% greater than the store. Valves shall be checked periodically on routine HSE inspections to ascertain that they are closed. Special consideration shall be given to any leakages arising from the surface run-off around temporary stockpiles of materials. All stationary diesel and petrol operated construction equipment shall have impervious drip trays placed beneath them during operation. Any spillages into the drip trays shall be collected for safe disposal. Vehicles and mobile equipment shall be regularly inspected and maintained to confirm they are not leaking or dripping. Operators shall be instructed in their HSE training to notify their supervisors if there occur any problems with their vehicles whereby appropriate maintenance be given. Maintenance of construction plant maintenance shall be closely supervised and measures shall be implemented to prevent hydrocarbon contamination. These measures shall include use of drip trays, absorbent materials close at hand and careful disposal of any used materials. Major equipment and vehicles shall be re-fuelled on an impervious base. Care shall be taken not to spill any fuel and absorbent materials be close at hand. Stationary equipment with impervious drip trays shall be re-fuelled in-situ; fuel containers shall be sealed after use and stored on an impervious base away from water bodies. Higher levels of dust containment shall be used for contaminated excavated material than used for other material. Appropriate measures may include: use of fine water sprays to thoroughly moisten all surfaces and maintain surface moisture; use of protective fences or screens to provide shelter from winds; minimising unnecessary handling of material and enclosure of excavated material in wind proof containers prior to removal from site. Spill ResponseThe magnitude of the discharge / spill shall determine the extent of the actions that have to be made necessary The key actions in responding to a spill to minimise its environmental impact are: An Early Detection. Regular inspections and training shall be carried out to enable an early detection. It is everyone’s responsibility to be aware of potential pollution risks. Notify Supervisor / Emergency Team Notify supervisor who shall notify the Site Manager or HSE Manager. Emergency services shall be notified as necessary. Assess Safety Risk To Humans Only attempt containment and cleanup operations of spilled substances when it can be performed safely. If spilled material is flammable, eliminate sources of ignition near spill area. Personnel and neighbours are to be evacuated if they are at risk Secure the area and establish perimeter control at a safe distance from the spill.
When it can be performed safely, stop source of spill. Pollution control equipment shall be available from site administration offices, storage and re-fuelling areas. Contain Spill (If Liquid).
No spills shall be rinsed away. Contaminated soils and clean-up materials from spills must be handled properly using personal protective equipment. These should be stored in a suitable container that is then labelled and taken away to be further stored in the appropriate location for subsequent safe disposal. Screen / cover stockpiles of polluted matter to prevent dispersion. Dispose With Care. Contaminated soils and used clean-up materials shall be treated as hazardous waste and be disposed of accordingly at a designated disposal site. Document Incident. The Site HSE Manager shall be responsible for ensuring a report is filed containing information on date, time, location, type and quantity of spilled material, description and cause of incident, action taken, name of person reporting the incident and recommended actions for ensuring the incident doesn’t reoccur. Spill Response MaterialsSpill response / pollution control materials shall be stored in a safe location on site in close proximity to the storage and waste areas. This material is to be used to contain and clean up pollution for that care shall be taken to dispose of any absorbent materials properly. They shall not be washed away. The Site HSE Manager shall keep stocks well maintained and replenished. Spill Response materials shall include the following: Sand / Sand bags / Buckets and Shovels / Storage Containers Sand is one of the most versatile containment materials which can be used to soak up spillages of oil, chemicals and used in sand bags to block off substances from sensitive areas or channel them to a predetermined collection point. Sand stocks must be dry and buckets with shovels readily available. Mechanical loading shovels, excavators and dump trucks may also be available for sand distribution and clean up. Storage containers for contaminated materials and earth shall be bund, located in the waste storage area, labelled and treated as hazardous waste. Waste ManagementIt is Contractor’s policy to minimise and reuse / recycle waste materials whenever possible and to dispose of remaining wastes in accordance with this Procedure. Before wastes can be disposed of appropriately, these first need be categorised and segregated. This in practice is often made difficult due to the wide range of solid, chemical and effluent waste that needs to be segregated stored and disposed of. The Site Manager is held responsible for the allocation of a trained official to guide and control the classification, storage, handling, transport and disposal of wastes. Waste can generally be classified as either: Domestic and municipal waste Non-hazardous industrial waste Hazardous waste. In table 2, over, the storage and disposal methods for re-usable / recyclable materials, domestic waste, non-hazardous construction waste, hazardous waste and waste water and sanitary waste are described. Table 2: Waste Storage and Disposal Controls
Dust and EmissionsThe most prevalent construction emission is fugitive dust, however, emissions of Carbon mono-oxide “CO” and related exhaust gases are likely to emerge from diesel generators as well as from activities such as on-site painting, re-fuelling of equipment, application of adhesives, waterproofing chemicals and the incomplete combustion of fuel in construction equipment. Note that none of the planned activities shall cause the release of H2S gas. The Dust and Emissions occurrence must be controlled during construction to an acceptable level by the following controllable suggestions: Avoid unnecessary idling of vehicles and machinery. Fuel, paint and chemical containers be kept sealed when not directly in use. All vehicles and Construction Plant be properly maintained to minimise excessive exhaust emission. Where possible, engines shall be located away from work areas. Should problems arise, for example defective equipment, which result in generation of fumes, gases or odours on-site, operators be instructed through their HSE Awareness Training to shut down and notify their supervisor to facilitate the appropriate mitigation response. Dust be controlled as far as is practicable. Control measures can significantly help minimise dust in most cases, apart from in the case of sand storms. If a severe sand storm occurs, the Site Manager should decide if work needs to shut down. After the storm, the roads should be cleaned. Fugitive dust emissions should be minimised by implementing the following controls: Water spraying. This shall be conducted at a frequency to keep the surfaces moist. Treated wastewater or ground water shall be used for this purpose. All the concerned persons shall be required to fully cover with sheeting or spray water on open-bodied trucks hauling sand, gravel or soil between on-site and off-site areas. Any transgressions should be immediately brought to the attention of the hauler concerned by the Site HSE Manager. Failure to comply with this requirement shall result in the offender being prevented from accessing the site. If sandblasting operations are required, these operations should be located and scheduled so as to minimise noise and dusting effects on adjacent work areas. Excavation faces not being worked should, if required, be moistened. Deliveries of finely ground materials should be in bag form or stockpiled in specified locations where the material can be suitably covered. Minimum drop heights shall be used during material transfer. The roads around the site particularly at the site entrance shall be monitored on a regular basis. These shall be kept as clear from dust and dirt as is practicable. Should it found to be necessary, the road in the vicinity of the site entrance shall also be swept. Construction personnel shall be required to enter the site over prepared surfaces and park in designated lots. Should problem areas arise which result in excessive dust generation on-site, workers should be instructed through their HSE Awareness Training to notify their supervisor to facilitate the appropriate response.
TrafficThe following traffic controls shall apply: Construction area access shall be limited to only for construction vehicles. Non-essential vehicles parking on site shall be restricted to designated areas. Site access shall be limited to established roadways and traffic shall be routed to the site avoiding residential areas as far as is practicable. The majority of construction vehicles shall be restricted to designated parking areas for that parking regulations be established and enforced. All road surfaces be maintained in safe and passable conditions. Vehicle washing facilities be on site.
Environmental Friendly PracticesEnvironmental Friendly Construction PracticesFollow all permit and environmental mitigation requirements. Stay within project boundary. Watch for and avoid flagged exclusion zones onsite. Leave wildlife and vegetation alone. Conduct with care project activities that can affect wildlife and vegetation (e.g. clearing) to avoid unnecessary disturbance. Do not dump waste in streams, ponds, lakes, rivers, wetlands, natural drainages or other sensitive areas. Implement and maintain erosion control and storm water measures as appropriate such as drainage ditches and trenches to divert flows away from active work areas, structures to prevent situation from reaching surface waters and sedimentation ponds to settle out storm water particulates. Place drip pans under all standing mobile equipment. Respond to spills by stopping the source of the spill and immediately notifying the supervisor. Contain any spill and clean it up using absorbent materials. Do not rinse spill away. Document, report type and quantity of spilled material, date, time, and cause of spill and cleanup as required. Maintain equipment in proper operating condition. Stockpile overburden, spoil, and fill at least 50 feet from surface water and wetlands whenever possible. Recycle treated wastewater as dust control if allowed and where practicable. Avoid using oil as a dust suppressant. Store wastes in properly designated areas. Label all containers accurately. Store hazardous waste securely in closed containers. Ship hazardous wastes to appropriate treatment and disposal facilities per local requirements. Do not burn anything except untreated wood. Recycle / reuse welding rods, used batteries, used oil, solvents, paints, paper, glass, scrap wood or metal, where required and as much as possible. Immediately stop work and notify the supervisor if human remains or archaeological artefacts are found. Immediately stop work and notify your supervisor, if contaminated soil (unusual colouration or odour) or underground storage tanks are discovered. Ask your Supervisor or Environment, Safety and Health representative if you have any questions. -------------------------------- Chapter 15
