Paragraph 11 Compliance: emissionsF1

SEPA must regard emission limit values in waste gases as having been complied with where—

(a)

in the case of continuous measurements—

(i)

none of the arithmetic averages of all valid readings taken during any 24-hour period of operation of an installation or activity except start-up and shut-down operations and maintenance of equipment exceeds the emission limit values,

(ii)

none of the hourly averages exceeds the emission limit values by more than a factor of 1.5,

(b)

in the case of periodic measurements if, in one monitoring exercise—

(i)

the average of all the measurement values does not exceed the emission limit values,

(ii)

none of the hourly averages exceeds the emission limit value by more than a factor of 1.5,

(c)

compliance with conditions imposed under paragraph 7 of this schedule are to be verified on the basis of the sum of the mass concentrations of the individual volatile organic compounds concerned,

(d)

for all other cases, compliance is to be verified on the basis of the total mass of organic carbon emitted unless otherwise specified in paragraph 13 of this schedule,

(e)

gas volumes may be added to the waste gas for cooling or dilution purposes where technically justified but is not to be considered when determining the mass concentration of the pollutant in the waste gas.
