On 17 January 1977, the Region of Lombardy approved ordinance no. 2, that, pursuant to the provision converting the legislative decree of August 1976, defined the action plans to be approved by the Regional Council, and introduced simplified procedures concerning urban design, accounting, hiring and regulation of the proceedings. Each programme had to determine the specific objectives it wanted to achieve, competences of various agencies with respect to the interventions to be completed, time necessary for each intervention and total necessary amount to be allocated for each intervention. While the regional agencies were busy organizing, also at legislative level in the first months of 1977 the authorities had to face the problem of unauthorized entries into the contaminated areas by the evacuees, a situation that was repeated for many months. Between September 1976 and February 1977, the agencies which were responsible for monitoring “Zone A,” denounced the presence of unauthorized persons.
