THE ENVIRONMENTAL IMPACT AND RISK GENERATED BY THE EXTRACTION IN QUARRIES OF CONSTRUCTION ROCKS - CASE STUDY TURCOAIA QUARRY PUBLISHEDMihai Nicolae TIBA None email@example.com
At present, in Tulcea County there are 50 quarries, of different sizes, that occupy a total area of 792 ha and which have as objective the extraction of useful rocks and building materials. Of these, 37 quarries are licensed to operate, the remaining 13 quarries need re-evaluations to obtain new authorizations, in order to be in compliance with the legislation in force. Porphyries are exploited from Consul, Cârjelari and Camena Hills; granites from Măcin, Turcoaia and Cerna quarries; limestone is exploited as building rock from Zebil, Bididia, Three Fountains and South Malcoci quarries; dolomite limestone from Mahmudia quarry is exploited for ArcelorMittal Galati; ornamental rocks (greasy limestone) from Baschioi and dolomite limestone of Mahmudia, Cârjelari and Codru Babadag quarries; basic rocks (used in road and railway construction works) are exploited from Niculiţel Hills area. Starting from this situation, the present study presents an impact and environmental risk assessment of the mining activity carried out in the largest quarry in the area, namely Turcoaia Quarry (at this moment the quarry is subjected to a re-evaluation process by the National Environmental Protection Agency in order to obtain an integrated authorization). For this purpose, based on the data provided by the activity holder, the environmental impact and risk generated by the extraction process is assessed using two procedures, namely the Rapid Impact Assessment Matrix (RIAM) and Integrated Impact and Environmental Risk Assessment (IIERA).
