Schedule 15 NEW SCHEDULE 24 TO BE ADDED INTO THE 2018 REGULATIONS

“SCHEDULE 24

TITANIUM DIOXIDE ACTIVITIES

Regulation 6(1)

PART 1

Scope and Interpretation

Scope and interpretation

1.

(1)

This schedule applies to titanium dioxide activities,

(2)

A “titanium dioxide activity” means—

(a)

a schedule 20 emissions activity producing titanium dioxide,

(b)

an organic solvent emissions activity producing titanium dioxide.

PART 2

Amendments to the common framework provisions

Authorisation conditions: disposal of waste

2.

SEPA must ensure that an authorisation for a titanium dioxide activity includes such conditions as it considers appropriate to ensure the prohibition of the disposal into the water environment of any of the following waste—

(a)

Solid waste,

(b)

the mother liquors arising from the filtration phase following hydrolysis of the titanyl sulphate solution from installations applying the sulphate process, including, but not limited to—

(i)

the acid waste associated with such liquors, containing overall more than 0.5% free sulphuric acid and various heavy metals, and

(ii)

mother liquors which have been diluted until they contain 0.5% or less free sulphuric acid,

(c)

waste from installations applying the chloride process containing more than 0.5% free hydrochloric acid and various heavy metals, including such waste which has been diluted until it contains 0.5% or less free hydrochloric acid,

(d)

filtration salts, sludges and liquid waste arising from the treatment (concentration or neutralisation) of the waste mentioned under sub-paragraphs (b) and (c) and containing various heavy metals, but not including neutralised and filtered or decanted waste containing only traces of heavy metals and which, before any dilution, has a pH value above 5.5.

Emissions: water

3.

(1)

SEPA must ensure that an authorisation for a titanium dioxide activity includes such conditions as it considers appropriate to ensure that emissions into water from installations do not exceed the emission limit values set out in this paragraph.

(2)

Emissions from installations using the sulphate process, as an annual average, must not exceed 550 kilograms of sulphate per tonne of titanium dioxide produced.

(3)

Emissions from installations using the chloride process, as an annual average must not exceed—

(a)

130 kilograms of chloride per tonne of titanium dioxide produced using neutral rutile,

(b)

228 kilograms of chloride per tonne of titanium dioxide produced using synthetic rutile,

(c)

330 kilograms of chloride per tonne of titanium dioxide produced using slag unless sub-paragraph (d) applies,

(d)

this sub-paragraph applies where installations discharge waste into salt water (estuarine, coastal, open sea),

(e)

where sub-paragraph (d) applies, installations may be subject to an emission limit value of 450 kilograms of chloride per tonne of titanium dioxide produced using slag.

(4)

For installations using—

(a)

the chloride process, and

(b)

more than one type of ore,

the emissions limit values in sub-paragraph (3) apply in proportion to the quantity of ores used.

Emissions: air

4.

(1)

SEPA must ensure that an authorisation for a titanium dioxide activity includes such conditions as it considers appropriate to ensure—

(a)

the prevention of the emission of acid droplets from installations,

(b)

that emissions into air from installations do not exceed the emission limit values set out in sub-paragraphs (2) to (5).

(2)

Emissions for dust must not exceed—

(a)

50 mg/Nm³ as an hourly average from major sources,

(b)

150 mg/Nm³ as an hourly average from any other source.

(3)

Emissions for gaseous sulphur dioxide and trioxide discharged from digestion and calcination—

(a)

6 kilograms per tonne of titanium dioxide produced as an annual average,

(b)

500 mg/Nm³ as an hourly average for plants for the concentration of waste acid.

(4)

The emission limit values in sub-paragraph (3) include acid droplets calculated as a sulphur dioxide equivalent.

(5)

Emissions for chlorine in the case of installations using the chloride process must not exceed—

(a)

5 mg/Nm³ as a daily average,

(b)

40 mg/Nm³ at any time.

(6)

Emissions limit values in this paragraph expressed in mass per cubic meter (Nm³) are to be calculated at a temperature of 273.15K and a pressure of 101.3kPa.

Emissions: monitoring and compliance

5.

SEPA must ensure that an authorisation for a titanium dioxide activity includes such conditions as it considers appropriate to ensure—

(a)

the monitoring to verify compliance with permit conditions of—

(i)

emissions into water,

(ii)

emissions into air,

(b)

the reporting of the resulting of monitoring referred to in sub-paragraph (a),

(c)

that the monitoring conditions referred to in sub-paragraph (a) includes continuous monitoring into air of—

(i)

gaseous sulphur dioxide and trioxide discharged from digestion and calcination from plants for the concentration of waste acid in installations using the sulphate process,

(ii)

chlorine from major sources within installations using the chloride process,

(iii)

dust from major sources,

(d)

that monitoring is carried out in accordance with—

(i)

relevant British or CEN standards, or

(ii)

where relevant British or CEN standards are not available, ISO or other international standards which ensure the provision of data or an equivalent scientific quality.”
