The Contractor is obligated to educate their personnel on the importance of remaining vigilant against any practices that could negatively impact our vital vegetation. It is essential to preserve the natural vegetation present on the site, ensuring it remains as undisturbed as possible. Any vegetation introduced to the site must consist of indigenous species and adhere to the guidelines provided by the Engineer. Only those trees and shrubs directly impacted by the construction activities, as well as any additional specimens specified in writing by the Engineer, may be removed. In woodland areas where indigenous vegetation has been cleared for necessary reasons, efforts must be made to re-establish the same species of indigenous trees that previously thrived there. The removal of protected trees is strictly prohibited without prior authorization from the Department of Forestry, Fisheries and Environment. Noncompliance with the regulations regarding listed protected tree species under the National Forests Act, 1998, is classified as a serious offence. Offenders may face substantial penalties, which include fines or imprisonment for a duration of up to three years, or both. It is imperative for the DEO to stay informed about the most current gazette regarding declared protected trees. Rehabilitation efforts must exclusively utilize indigenous tree, shrub, and grass species. Particular care must be given to any search and rescue operations identified during the environmental assessment phase, with provisions made for the removal of affected specimens to an on-site nursery for ongoing care and protection, followed by subsequent replanting. Any declared weed or invasive species that emerges during the contract period must be removed by hand prior to seeding activities. Open flames are permitted solely in designated facilities or equipment constructed expressly for this function. The need for the establishment of firebreaks will be assessed in consultation with the Engineer and relevant authorities; where necessary, firebreaks will be cleared and maintained around the perimeter of the camp and office locations to mitigate fire hazards. Update (2024-11-08): The site establishment plan shall prioritize sustainable sewage management practices for the waste generated from site offices, laboratories, staff accommodations, and areas with high labor concentrations. Sanitary facilities must meet the standards set by the Engineer, comply with local regulations, and adhere to legal requirements. To ensure safe and effective sewage treatment, the site will implement one of the following eco-friendly waste management solutions: septic tanks with soak-aways, dry-composting toilets such as “enviro loos,” or the use of chemical toilets maintained by accredited service providers. The appropriate sewage management system will be determined based on the local geology, the project duration, and the availability of chemical toilet services. Waste generated from these systems will be serviced regularly to maintain hygiene. The placement of chemical toilets will be coordinated with the Engineer to ensure optimal function. If a soak-away system is utilized, it must be situated no closer than 800 meters from any natural watercourse or water retention system and will require approval from the Engineer in conjunction with the Environmental Compliance Officer (ECO). Sanitary facilities must be readily accessible and located within a convenient walking distance for all employees on-site. Under no circumstances should the natural environment be used as a toilet. Outdoor toilets will be equipped with secure locks and doors to prevent displacement by wind, and they will be situated away from areas prone to flooding. The Contractor will be responsible for the regular emptying of toilet facilities and will ensure compliance with their use. Furthermore, the Contractor must maintain these facilities in a clean, orderly, and sanitary manner, meeting the satisfaction of the Engineer. Update (2024-11-10): The Contractor's planned waste management strategies must be detailed and executed from the commencement of the contract, ensuring full alignment with the expectations of the Engineer. A comprehensive waste inventory should be established to catalog all potential waste streams generated by the site or project, employing an integrated approach to their stewardship. Thorough records of all waste disposal activities must be maintained. Prior to project initiation, opportunities for waste avoidance, reduction, reuse, and recycling should be thoroughly identified, along with any constraints that may hinder their effective implementation. All personnel will receive training on the appropriate disposal methods for all waste materials. i) Solid Waste Solid waste must be stored in designated areas utilizing covered, tip-resistant metal drums or similar containers to ensure safe collection and disposal. Disposal of solid waste should occur exclusively at licensed landfill sites or at locations approved by the appropriate regulatory authorities, particularly if a functioning landfill is not readily accessible. Burning or burying waste within or near the project area is strictly prohibited. ii) Litter Littering by construction workers will not be tolerated, with a strong emphasis on litter control measures enforced at stop/go facilities. Throughout the construction phase, the various contractor facilities must be maintained in an orderly and clean manner, with the site kept free of litter. At all work locations, the Contractor will be required to provide facilities for litter collection, ensuring safe disposal at approved sites. iii) Hazardous Waste Hazardous waste, including oils, must be disposed of at authorized landfill sites, with the Contractor responsible for maintaining proof of such disposal activities. Precautionary measures must be in place to prevent the spillage of bituminous products—including binders or pre-coating fluids—thereby safeguarding against water-soluble phenols contaminating the soil or surface water. Under no circumstances should bituminous products be discarded on-site, over embankments, within borrow pits, or via any burial methods. Any unused or rejected bituminous products must be returned to the supplier’s manufacturing facility. Immediate action must be taken to address any spills of bituminous materials, and affected areas must be reinstated promptly to the Engineer's satisfaction. iv) Construction and Demolition Waste Opportunities for recycling and reusing construction and demolition waste, particularly as fill for road embankments, land reclamation, and drainage management, must be thoroughly assessed and prioritized before categorizing these materials as 'waste.'
