PART 1Permit conditions
Monitoring6
1
The operator of a medium combustion plant must—
a
where the plant is using more than one fuel type, monitor emissions—
i
while the fuel or fuel mix likely to result in the highest level of emissions is being fired, and
ii
during a period which is representative of normal operating conditions,
b
keep a record of, and process, all monitoring results in such a way as to enable verification of compliance with the applicable emission limit values,
c
keep a record of, or information proving, the effective continuous operation of secondary abatement equipment in use at the plant,
d
keep the following:—
i
the permit and, if relevant, variations and related information,
ii
the monitoring results and information referred to in sub-paragraphs (b) and (c),
iii
a record of the plant’s operating hours if applicable for the purposes of paragraph 1(3) or 2(2),
iii
a record of the type and quantities of fuel used in the plant,
iv
a record of any breakdown or malfunction of secondary abatement equipment,
v
a record of a breach of an emission limit value, and the measures taken by the operator to restore compliance,
e
keep the information referred to in head (d)(ii) to (v) for a period of at least 6 years.
2
The operator of a medium combustion plant must either—
a
measure emissions at least every three years; or
b
measure emissions continuously.
3
But where sub-paragraph (4) applies, the operator must measure emissions at the most frequent of—
a
after the elapse of three times the maximum permitted average annual operating hours,
b
every five years.
4
This paragraph applies to a medium combustion plant which is—
a
exempted from the requirements of paragraph 1(1) and (2) by paragraph 1(3), or
b
exempted from the requirements of paragraph 2(1) by paragraph 2(2).
5
The operator of a medium combustion plant is only required to measure emissions of—
a
pollutants for which an emission limit value is included in the operator’s permit by virtue of this schedule, and
b
carbon monoxide.
6
The operator of a medium combustion plant must take the first measurement of emissions by the later of the date falling 4 months after—
a
the grant of the permit,
b
the date of the start of operation of the plant.
7
As an alternative to the requirements of sub-paragraphs (2), (3) and (5)(a), the operator of a medium combustion plant may use other procedures which have been verified and approved by SEPA to determine SO2 emissions from the plant.
8
Where an operator is required to measure emissions continuously—
a
the measuring systems must be subject to checking by means of parallel measurements with the reference methods at least annually, and
b
the operator must provide the results of the check to SEPA.
9
Measurements must be taken when—
a
the plant is operating under stable conditions at a representative even load, and
b
the plant is not starting-up or shutting down.
