Leather/Skin/Hide Processing Industry - Environmental Clearance

Operational Aspects of EIAreaches to an agreed level of source control+other interventions (together called asmitigation measures in the given context) that achieve the targeted protection levelsfor the valued environmental components in the receiving environment. These levelswill become the principle clearance conditions.Chapter 3 of this TGM offers elaborate information on cleaner technologies, wasteminimization opportunities, and control technologies for various kinds of pollutingparameters that emanate from this developmental activity. This information may beused to draw appropriate source control measures.The choice of interventions for mitigation of impacts may also be numerous and dependon various factors. Mitigation measures based on location-specific suitability and someother factors are discussed in sub-sections 4.6.1 and 4.6.2. A few typical measures whichmay also be explored for mitigation of impacts are listed in Table 4-5.Table 4-4: Typical Mitigation MeasuresErosionImpactsResources – fuel/ constructionmaterial, etcDeforestationWater pollution and issuesDust pollutionNoise pollutionTypical Mitigation Measures Windscreens, maintenance, and installation of groundcover Installation of drainage ditches Runoff and retention ponds Minimize disturbances and scarification of the surface Optimization of resource use Availing resources with least impact – eco-efficiencyoptions are applicable Availing the resources which could be replenished bynatural systems, etc. Plant or create similar areas Initiate a tree planning program in other areas Donate land to conservationalist groups Channeling and retention of water to reduce erosion andsituation Collection and treatment of sewage and organic waste Increased recycling and reuse of water Use of biodegradable or otherwise readily treatableadditives Neutralization and sedimentation of wastewater Dewatering of sludge and appropriate disposal of solids Use deep well injection below potable levels Construct liners of ponds and solids waste disposal Dilute water at point of discharge Providing a stormwater network within the plant toprevent cross contamination with the effluents Minimise flow variation from the mean flow Wetting of roadways to reduce traffic dust and reentrainedparticles Installation of windscreens to breakup the wind flow Provide dust collector equipment Heavy duty muffler systems on heavy equipment Limit certain activities By using damping, absorption, dissipation, anddeflection methods Maintain noise levels from below 90 dbaTGM for Tanneries August 20104-32
