NOT PROTECTIVELY MARKED6.3.3 Inert Non-Radioactive Waste278. Inert waste is a sub-category of non-hazardous waste. Under EPR2010 it includes anywaste that does not undergo significant physical, chemical or biological transformations. Itdoes not dissolve, burn or physically or chemically react and its leachability and leachate donot endanger the environment. As a result the waste acceptance criteria testing for nongenericinert wastes are more onerous than for non-hazardous waste. Management routesfor inert non-radioactive waste are given below.TypeConcrete /Building RubbleSoilWaste Management RouteConcrete and building rubble is monitored as clean or belowexempt (out of scope) levels and reused on-site as infill wherepossible. Surplus material is sent for disposal to an inertlandfill.Soil is monitored as clean or below exempt (out of scope)levels and replaced or used on-site for landscaping.279. Inert non-radioactive waste consists mainly of concrete or building rubble which can becrushed for reuse as infill on-site. This minimises the requirement to purchase cleanmaterial to fill voids produced during decommissioning. Use of material as infill requires anexemption under EPR 2010. This has become managerially more onerous now that theapplication forms require much more detail to be provided to the EA. In addition the EA isrequired to inspect each location/ operation which stretches their resources and causesdelay. Exemptions need to be sought on an individual basis rather than an annual genericbasis for the site. Soil removed during site remediation and found to be clean aftercharacterisation is replaced in its original location or used for landscaping.280.
