S.L. 549.79 Art. 8Compliance with emission limit values.

(1) In the case of continuous measurements the competent authority shall consider that emission limit values shall be complied with if:

(a) none of the averages over twenty-four hours of normal operation exceeds the emission limit values, and

(b) none of the hourly averages exceeds the emission limit values by more than a factor of 1.5.

(2) In the case of periodic measurements the emission limit values shall be considered by the competent authority to be complied with if, in one monitoring exercise:

(a) the average of all the readings does not exceed the emission limit values, and

(b) none of the hourly averages exceeds the emission limit value by more than a factor of 1.5.

(3) The competent authority shall ensure that compliance with the provisions of regulation 6(7) and (8) shall be verified on the basis of the sum of the mass concentrations of the individual volatile organic compounds concerned: Provided that for all other cases, compliance shall be verified on the bases of the total mass of organic carbon emitted unless otherwise specified in Schedule II:P

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