Paragraph 6 Authorisations: control of emissionsF1

waste gases are to be discharged in a controlled way by means of a stack the height of which is calculated in such a way as to safeguard human health and the environment,

emissions into air do not exceed the emission limit values set out in Chapters 3 and 4 of Part 3 of this schedule or are determined in accordance with Chapter 4 of Part 3 of this schedule,

where in a waste co-incineration plant more than 40% of the resulting heat release comes from hazardous waste, or where the plant co-incinerates untreated mixed municipal waste, the emission limit values set out in Chapter 3 of Part 3 of this schedule apply,

discharges to the aquatic environment of wastewater resulting from the cleaning of waste gases are limited as far as practicable and the concentrations of polluting substances does not exceed the emission limit values set out in Chapter 5 of Part 3 of this schedule at the point where waste waters from the cleaning of waste gases are discharged from the plant,

where waste waters from the cleaning of waste gases are treated outside the waste incineration or co-incineration plant, at a treatment plant intended only for the treatment of this sort of waste water, the emission limit values set out in Chapter 5 of Part 3 of this schedule are to be applied at the point where the waste waters leave the treatment plant,

where waste waters from the cleaning of waste gases are treated collectively with other sources of waste water, either on site or off site, the authorised person must make the appropriate mass balance calculations, using the results of the measurements set out in paragraph 27 of this schedule in order to determine the emission levels in the final waste water discharge that can be attributed to the waste water arising from the cleaning of waste gases,

for the purpose of complying with the emission limit values set out in Chapter 5 of Part 3 of this schedule, wastewater is not to be diluted,

waste incineration plant and co-incineration plant sites, including associated storage areas for waste, must be designed and operated in such a way as to prevent the unauthorised and accidental release of any polluting substances into soil, surface water and groundwater,

storage capacity must be provided for contaminated rainwater run-off from the waste incineration plant site or waste co-incineration plant site or for contaminated water arising from spillage or fire-fighting operations,

the storage capacity referred to in sub-paragraph (i) must be adequate to ensure that such waters can be tested and treated before discharge where necessary,

without prejudice to paragraph 8(1)(j)(iii) of this schedule, the plant or individual combustion chambers being part of a waste incineration plant or waste co-incineration plant must not continue to incinerate waste for a period of more than 4 hours uninterrupted where emission limit values are exceeded,

where one or more combustion chambers are linked to a single waste gas cleaning device, the cumulative duration of operation in conditions where emission limit values are exceeded must not exceed 60 hours over one year,

compliance with emission limit values for air and water is achieved where the conditions described in Chapter 8 of Part 3 of this schedule are satisfied.
