ITALY - 6 Hazardous Waste
C6.3.8.8.4.2. Provided for those existing tank systems when the tank system
annual leak test detects leakage;
1999;
C6.3.8.8.4.3. Provided for tank systems that store or treat HW by 1 January
C6.3.8.8.4.4. Provided for above-ground storage tank (AST) used for hazardous
waste storage. Each containment system shall meet the larger of the following volumes:
C6.3.8.8.4.4.1 Equal to the volume of the largest AST plus sufficient freeboard
to allow for precipitation and expansion of product
C6.3.8.8.4.4.2 Equal to one-third of the total capacity stored in the ASTs in the
containment system
C6.3.8.8.4.5. Designed, installed, and operated to prevent any migration of
wastes or accumulated liquid out of the system to the soil, groundwater, or surface water at any
time during the use of the tank system; and capable of detecting and collecting releases and
accumulated liquid until the collected material is removed; and
C6.3.8.8.4.6. Constructed to include one or more of the following: a liner
external to the tank, a vault, or double-walled tank.
C6.3.8.8.5. General Operating Requirements
C6.3.8.8.5.1. Hazardous wastes or treatment reagents must not be placed in a
tank system if they could cause the tank, its ancillary equipment, or the containment system to
rupture, leak, corrode, or otherwise fail.
day:
C6.3.8.8.5.2. The installation must inspect and log at least once each operating
C6.3.8.8.5.2.1 The above-ground portions of the tank system, if any, to detect
corrosion or releases of waste;
C6.3.8.8.5.2.2 Data gathered from monitoring and leak detection equipment
(e.g., pressure or temperature gauges, monitoring wells) to ensure that the tank system is being
operated according to its design; and
C6.3.8.8.5.2.3 The construction materials and the area immediately surrounding
the externally accessible portion of the tank system, including the secondary containment system
(e.g., dikes) to detect erosion or signs of releases of hazardous waste (e.g., wet spots, dead
vegetation).
C6.3.8.8.5.3. The installation must inspect cathodic protection systems to ensure
that they are functioning properly. The proper operation of the cathodic protection system must
be confirmed within six months after initial installation and annually thereafter. All sources of
impressed current must be inspected and/or tested, as appropriate, or at least every other month.
