Abstract: Leather sector in Ethiopia is the most focused area as a development reinforcing component. The sector is also known for its intensive environment polluting practices. The intensity of wastewater management problems calls for immediate solution in a tanning industry to maintain community wellbeing and sustain development. Tanning process of Batu tannery employs large amount of water and toxic chemicals generating large volume of wastewater mismanaged and discharged in to little Akaki River nearby. Improving tannery wastewater management and consequently reduce adverse environmental impacts thus identifying the pollution alleviating techniques employed in tanneries and showing environmental policy compliance gaps is the core essence of this study. Linkage and integration of the individual production process management and respective wastewater management is also evaluated. To answer the research questions concerning wastewater management efficiency, pollution load reduction techniques used and individual production process linkage with wastewater management practices of Batu tannery questionnaires were distributed in the factory on the bases of stratified sampling among four groups of workers and analyzed. Environmental adverse impact and policy compliance gaps related to tannery wastewater management is shown from information extracted through key informant response analysis and focus group discussion made among tannery wastewater recipient community for further evidence conformation. The study result revealed that, BTPLC tannery wastewater management lacks efficiency though there is a planned ambition and vision to respond to the modern environment and quality management systems. The result also indicated that individual production process management lacks systematized, consistent and integrated linkage with the wastewater management. Pollution reduction strategies involve very limited preventive waste management approach. Tannery process water and chemical consumption is inadequately controlled and wastewater treatment plant operational efficiency is inadequate. The study indicated that stakeholder intervention is needed in Batu tannery in areas of EMS installment, monitoring and evaluation, training, awareness creation, technology transfer and sounding regulatory system enrichment. Most of the policy issues related to tannery wastewater management problems are unclear and their compliance is limited. The finding showed that there is a gap in implementing environment policy related to wastewater management in Batu tannery. Government bodies responsible to enforce environmental policies are institutionally inadequate in this respect .The study also indicated that efforts to assess adverse environment impacts of the tannery waste management practices lack clarity and stakeholder commitment. Findings of this study also showed that the role of EIA in a leather sector, as an environmental management and decision making tool regarding overall effects of tannery wastewater in sustaining development is reluctantly implemented and involve limited public participation.
