6 Aspetti legislat
6.2 Normativa regionale
Il recepimento su scala regionale, per quanto riguarda la Regione Toscana, del D. Lgs. 22/97 si è avuto in prima istanza con la Legge Regionale 18 maggio 1998 n. 25 “Norme per la gestione dei rifiuti e la bonifica dei siti inquinati”, che ha introdotto nuove norme in materia di gestione dei rifiuti e per la messa in sicurezza, la bonifica ed il ripristino ambientale dei siti inquinati.
La legge, da ultimo modificata ed integrata dalla L. R. 26 luglio 2002, n. 29, disciplina le procedure amministrative gestionali degli interventi di bonifica e di riqualificazione ambientale, definendo il sistema delle competenze degli attori pubblici e privati, e dettaglia i contenuti, l’iter di approvazione e gli effetti del Piano regionale e dei Piani provinciali delle Bonifiche.
In linea con quanto previsto dalla normativa nazionale, l’onere delle operazioni di bonifica e/o messa in sicurezza grava sul soggetto che ha cagionato l’inquinamento, in solido con il proprietario e con i titolari dei diritti reali o personali di godimento sull’area. L’inadempimento dell’obbligato, in capo al quale restano comunque addebitate le spese sostenute per la realizzazione degli interventi, attiva la procedura d’ufficio da parte del Comune territorialmente competente, previa verifica della permanenza delle condizioni d’inquinamento, affidata all’ARPAT.
L’ultimo decreto regionale emanato, relativo a bonifiche e messa in sicurezza, è il D. P. G. R. n. 14/R., del 25 febbraio 2004, in sostituzione del D. P. G. R. n. 32 del luglio 2001, la Regione Toscana dà attuazione a quanto previsto dalla L. R. 25/98, definendo specifiche direttive tecniche e procedurali per l’esercizio delle funzioni
di gestione e di controllo attribuite agli Enti Locali in materia di bonifica e messa in sicurezza dei siti contaminati.
Principale strumento di governo e controllo presente sul territorio regionale è costituito dal Piano Regionale delle Bonifiche, approvato con deliberazione del Consiglio Regionale del 21 dicembre 1999 n. 384, nel quale sono contenuti gli obiettivi e i principi per la programmazione degli interventi di bonifica, individuando le priorità degli interventi sulla base delle caratteristiche generali
