ABSTRACT The Environmental impact study on a National, Departmental, Regional, and Local level have became important tools to determine the damage caused in a natural or social environment. Besides, they can help us to implement precautions to compensate the primary and secondary effects caused to these systems. This way, this diagnostic is an investigation proposal to analize and prioritize the main environmental impacts caused because of the gold mining activity on a municipal level. First of all, we mention the frame of reference, where we do a description of the study area, the conceptual and theoretical mining basis of the diagnostic, and the current legal standards which support it. The methodological process is about Problematics and Environmental evaluation with a qualitative and quantitative method application. It is to complement the descriptive analysis with the stadistic ones. This way we can get more precise information. The diagnostic carried out in three steps such as dianostic physical and biotic, impacts identification, and the consolidation of an environmental proposal. It is a process where the mining community participation was vital.
