Paragraph 15 Compliance and measurementF1

(1)

SEPA must periodically check compliance with authorisation conditions and, in the case of notifications, the applicable general binding rules, including emission limit values.

(2)

In the case of periodic measurements, an emission limit value is to be treated as being complied with if each of the series of measurements (or other procedures) do not exceed the emission limit value.

(3)

In the case of continuous measurements, an emission limit value is to be treated as being complied with if the evaluation of the measurement results indicates, for operating hours within a calendar year, that all of the following conditions have been met—

(a)

no validated monthly average value exceeds the emission limit value,

(b)

no validated daily average value exceeds 110% of the emission limit value,

(c)

in the case of plant composed only of boilers using coal, no validated daily average value exceeds 150% of the emission limit value,

(d)

95% of all the validated hourly average values over the year do not exceed 200% of the emission limit value.

(4)

At the emission limit value level, the values of the 95% confidence intervals of a single measured result must not exceed the following percentages of the emission limit values—

(a)

10% for emissions of carbon monoxide,

(b)

20% for emissions of sulphur dioxide,

(c)

20% for emissions of nitrogen oxides,

(d)

30% for dust.

(5)

The validated hourly and daily average values are determined from the measured valid hourly average values after having subtracted the value of the confidence interval specified in sub-paragraph (4).

(6)

A day is invalidated if more than three hourly average values are invalid due to malfunction or maintenance of the automated measuring system.

(7)

For the purpose of calculating average emission limit values the following periods are to be disregarded—

(a)

periods of start-up and shut-down, and

(b)

the periods referred to in paragraph 11 of this schedule.
