10. For paragraph 14 of Schedule 1 (criteria for granular stable non-reactive hazardous waste and non-hazardous waste deposited in the same cell with such waste) substitute—
14. Stable, non-reactive hazardous waste and non-hazardous waste which is to be landfilled in the same cell with such waste shall only be accepted if—
(a)in the case of granular waste–
(i)it meets the limit values for leaching set out in Table 4;
(ii)it meets the additional criteria set out in Table 5; and
(iii)it will have either–
(aa)if it is cohesive waste, a mean in situ shear strength of at least 50kPa; or
(bb)if it is non-cohesive waste, an in situ bearing ratio of at least 5%;
(b)in the case of monolithic waste–
(i)it meets either–
(aa)the limit values for leaching set out in Table 4; or
(bb)the limit values for leaching set out in Table 5A;
(ii)it meets the additional criteria set out in Table 5B;
(iii)it has a mean unconfined compressive strength of at least 1MPa after 28 days curing;
(iv)it has either–
(aa)dimensions of greater than 40cm along each side; or
(bb)a depth and fracture spacing when hardened of greater than 40cm; and
(v)where the waste was subjected to treatment to render it monolithic, prior to such treatment it met the following limit values—
(aa)Loss on Ignition of 10%; or
(bb)Total Organic Carbon of 6%.
Component | Symbol | L/S = 10 l/kg(a) |
---|---|---|
mg/kg dry substance | ||
(a) These values must be determined using EN 12457/1 to 3 (applied, in the case of monolithic waste, to a sample which has been crushed). | ||
(b) If the waste does not meet this value for Dissolved Organic Carbon (DOC) at its own pH, it may alternatively be tested at L/S = 10 l/kg and a pH of between 7.5 and 8.0. The waste shall be considered as complying with the acceptance criterion for DOC if the result of this determination does not exceed 800 mg/kg. | ||
(c) The value for Total Dissolved Solids can be used alternatively to the values for Sulphate and Chloride. | ||

(a) If this value is not achieved, a higher limit value may be permitted by the Chief Inspector, provided that the Dissolved Organic Carbon value of 800 mg/kg is achieved at L/S=10l/kg, either at the material’s own pH or at a pH value between 7.5 and 8.0. | |
Total Organic Carbon (TOC) | 5%(a) |
pH | Minimum 6 |
Acid Neutralisation Capacity (ANC) | Must be evaluated |

(a) These values must be determined using EA NEN 7375:2004. Where it is appropriate for compliance testing, the Chief Inspector may specify use of a shortened version of the 64-day tank test provided for in EA NEN 7375:2004 comprising only the first four steps, and in such cases, the limit values shall be a quarter of the values in the table. | ||
