SUMMARY:

Sewage treatment plants (STPs), despite being fundamental for controlling environmental pollution, are also potential causes of environmental impact, therefore requiring an efficient self-monitoring plan to verify compliance with legal conditions. In this context, this research investigated the situation of Sewage Treatment Stations of enterprises that develop activities with high polluting degrading potential, located in Juazeiro do Norte – CE, in relation to compliance with legal guidelines. To guide this analysis, conditions were considered in resolutions from the Ceará State Environmental Council and municipal laws and decrees that deal with the matter under consideration. At the Municipal Environmental Authority of Juazeiro do Norte (AMAJU), data were collected from licensed enterprises that carried out high PPD activities, from the treatment technologies for effluents generated in each activity, from the ETE self-monitoring programs, and the types and locations of bodies receivers and the operating condition and physical flow of the monitoring sector. The processing of data regarding the delivery of self-monitoring reports was carried out using the 50 and 75% percentiles. From the analysis of the results, 70 enterprises were identified that developed high PPD activities that were under the jurisdiction of AMAJU, of which 4 were located in areas that had restrictions on this type of use. It was also verified that there was an important battery of public water supply wells surrounded by such projects. It was found that of the 70 high PPD projects, 48 generated liquid effluents. Of this total, only 35 submitted self-monitoring reports. Regarding the quality of liquid effluents from the ETEs of these 35 projects, it was verified that, under specific conditions, it was in compliance with the discharge standards established by COEMA Resolution No. 02/2019. However, it was found that the majority of the enterprises surveyed were non-compliant regarding the quantity and frequency of sending self-monitoring reports to AMAJU. This non-conformity was attributed to the reduced technical staff of the environmental agency and the absence of a minimum infrastructure necessary for the development of actions to implement an efficient environmental monitoring system. To contribute to the improvement of this system, it was suggested to strengthen AMAJU's technical, financial and institutional support, in addition to establishing a distinction in relation to the requirements regarding the frequency of analyzes and the periodicity of delivery of liquid effluent self-monitoring reports, for enterprises. with different types and classes.
