This study was aimed to evaluate existing EIA documents available for established factories and thereby identify the gaps of EIA study reports in Burayu town, Tatek Industry Zone as per the standard guideline of the EFCCC. Hence, there were two hundred two different factoriesâ€™ EIASR were available in Burayu town Environment, Forest and Climate Change Authority and the whole documents were accessed for evaluation. The design to evaluate the EIA reports was followed EFCCC (former EPA) EIASR review guideline, 2003. In addition to this, the study applied an interview with regulatory body and the proponents (the owners of the factories). The whole accessed EIASR were evaluated through developing a checklist that based on a Liker scale rated between 1-5 values, and before analysis, the validity & reliability of the variables were tested, then analyzed by using SPSS-20 and the result was interpreted. Whereas, the data collected through an interview by using KII & observation was analyzed qualitatively and interpreted accordingly. The EIA study report rated based on Liker scale were evaluated through the mean score of the variables generated using the SPSS-20 as compared to the Liker scale value and each of the contents of the reports were categorized into: Not satisfactory at all, Unsatisfactory, moderately satisfactory, highly satisfactory, and very highly satisfactory. Based on this, the result of the evaluated documents mean scores was resulted in 50% of the factoriesâ€™ EIA document contents were unsatisfied, 30% moderately satisfied 10% not satisfied at all, and only 10% of the reportsâ€™ content valued highly satisfied. This indicated that the EIASR prepared for factories in the study area were not fulfilled the standards of the EFCCC (former EPA) review guideline. These gaps were might arise from the low capacity of the consulting firm who were prepared the report and inadequate knowledge of the reviewer (regulatory body). As the data obtained from an interview of the regulatory body, the consulting firms influenced by their customers (factory owners), and they were done their assumption than the reality on the ground and also said, there was lack of enough number& well-equipped experts in the authority & low power to implement the rules & regulations, a low commitment of the government to enforce the investors to undertake an EIASR properly, the investors also seen an EIA as a threat that hinders an investment & not interested to undertake it, and still there were investors who operate a factory without EIASR.
