KARNATAKA MUNICIPAL WATER PUMPING IMPROVEMENTS IN SIX TOWNSENVIRONMENTAL AUDIT AND PREPARING ENVIRONMENTAL MANAGEMENT PLANFINAL REPORTinduced directly by the project where as the secondary impacts are those which are indirectlyinduced and typically include the associated investments and changing patterns of social andeconomic changes due to the proposed actionThe audit for environmental impacts is broken down into four categories, coinciding with theimplementation phases of the project:Location ImpactsThe location of recommendations for energy efficiency is at existing pumping stations. Thepumping stations for Malprabha as well as Neerasgar scheme are located within agricultural andbarren land. There are no settlements in close proximity of the Pumping stations. The ambientenvironmental conditions were observed to be free from any kind of pollution. Since the existingenvironment is a built environment, no land acquisition is expected and recommendations wouldbe carried on the same locations, no location impacts are considered likely.Impacts due to energy efficiency recommendationsAs the recommendations are more of upgrading existing systems with technologically superiormechanical and electrical components, no impact is anticipated. Moreover most of therecommendations like surrendering of excess contract demand, increasing pf values are policyand efficiency level decisions and are unlikely to have any environmental impact.Implementation/ Construction ImpactsMost of the physical recommendations proposed at Malaprabha Scheme pumping stations arecurrently being implemented under KWASSIP and hence no impacts are likely. A pumping stationhas been constructed at Jack Well location and an EMP has been implemented for the sameunder KWASSIP project. The recommendation for energy efficiency do not envisage any furtherconstruction works and unlikely to have any impact.Operation and Maintenance ImpactsDuring operation phase there are likely to be non-significant and reversible impacts in the projectarea which are likely to affect the workers. These include high noise and vibrations level, wastedisposal of maintenance related materials and safety for workers from likely accidents.1. Impact due to noise and vibrations level: The pumping stations are expected to be operated allthrough the day. Since there are no sensitive locations or settlements at the locations of the allpumping stations, very minimal impact is envisaged. However the noise and vibrations might leadto nuisances to workers. The pumping equipments have high noise levels in the range of 80 - 95dB (A) depending on the type of machinery used, which can affect the personnel operating themachines. The workers in general are likely to be exposed to an equivalent noise level of 80 to 90dB (A) in an 8-hour shift, for which all precautions should be taken into consideration.Mitigation MeasuresMitigation measures are suggested for workers and pumping machineries. Since the pumpingmachinery has been already installed and in operations no specific engineering noise controlmeasures would be applicable. Implementation measures are suggested for protection of workersfrom high and continuous noise. Full mitigation for noise impact is not expected.Mitigation for workers would include• The operator and worker areas for sitting or resting shall be located away from pumpingmachinery locations• Workers shall be provided with noise protection measures like Personal ProtectiveEquipment (PPE) such as earmuffs (over-the-head type)24 World Bank
KARNATAKA MUNICIPAL WATER PUMPING IMPROVEMENTS IN SIX TOWNSENVIRONMENTAL AUDIT AND PREPARING ENVIRONMENTAL MANAGEMENT PLANFINAL REPORT• To prevent long term health implications Regular annual health checkups for the workersshall to be taken up.• Noise monitoring shall be taken up at the pumping station locations.Noise Mitigation techniques for pumping machinery would include:• Regular maintenance of pumping machinery shall be taken up as per specifications of themanufacturer.• Vegetation planting 4 around periphery boundary of pumping stations shall be taken up.2. Generation of waste and disposal: Periodic maintenance of the pumping equipments, electricalpanels and pump house structure might lead to generation and storage of waste like oil, scrap,electrical equipments and grease. Although the quantity of the waste generation is not substantial,due care needs to be taken for disposal.Mitigation Measures• Different types of waste shall be segregated and stored in different containers to enhancereuse or recycling of materials and their proper disposal• Record of type, amount of wastes generated, recycled and disposed (including thedisposal sites) shall be maintained in separate register• The disposal shall not be done at sensitive locations, natural water bodies or nearsettlements. Waste like oil, grease/lubricant, metal scrap and building debris should bedisposed off to designated dealers or designated locations with prior approval from therespective Municipal engineers.3. Operational Health and Safety of workers: Specific impacts in this phase include hazards tohealth and safety of workmen working in the pumping station. The following occupational healthissues may be encountered during pumping activities:• Physical hazards in pumping operations may be related to handling of large, heavymaterials and machine parts; accidents related to heavy mechanical movement; injuriesdue to machinery accidents; and injuries due to falls from elevation (e.g. high platforms,ladders, and stairs).• Electrical and fire hazards related to shocks, fires due to faults in electrical panelsMitigation Measures• Occupational health and safety 5 provisions and implementation should be included in O&MContract of pumping stations.• Occupational Health and Safety Plan for workforce should be implemented for protectionagainst physical, electrical and fire hazards with due provision of appropriate protectiveequipments and gears to workers on the site.• Training for workers on handling potential site emergencies, dangers, including potentialhealth effects4 Guidelines suggested and indicative tree/shrub list has been given in Annexure E5• Operational Health and Safety precautions in India are covered under The Factories Act, 1948. This is not a regulatoryrequirement for pumping stations as they would not come under the purview of the aforesaid Act. The pumping station couldadhere to relevant health section (Chapter-III section 11, 12, 13, 14, 17, 18 and 19) and safety (Chapter-IV Section 21, 22,28, 38 and 40) guidelines suggested in The Factories Act, 1948 with subsequent amendments. Occupational Health andSafety Instruction to be a part of O&M are given in annexure -C25 World Bank
