QuestionView source ↗
(1) Has Cockburn Cement Limited (CCL)
applied to the department to conduct an “odour neutralisation trial” at its
Munster premises licensed under Part V of the Environmental Protection Act 1986 ? (2) Has the application been
approved? (3) If yes to (2), when was it approved and under what conditions was approval granted? (4) If no to (2), when will the Department make
a decision on the application? (5) Does the application state
that CCL intends to inject a fine mist of water into the gas stream from one or
both of the lime kilns at its Munster premises? (6) Does the gas stream from the kilns contain sulphur dioxide, nitrogen dioxide, hydrogen chloride, carbon
dioxide (acid gases) and other toxic gases and particulates? (7) Will the injection of a fine
mist of water into a stream of acid gases create sulphuric acid, nitric acid,
hydrochloric acid and/or carbonic acid (Acid Rain)? (8) If no to (7), why not? (9) If yes to (7), what measures does CCL propose to prevent acid
rain being emitted from the chimney stacks of the kilns? (10) If yes to (7), what conditions does the
Department propose to impose on CCL to prevent acid rain being emitted from
each kiln stack? (11) If CCL was permitted to burn only natural gas in
the kilns instead of coal, would the quantity of acid gases emitted from the kilns be reduced, based on the known compounds in the natural gas already being
used by CCL in the kilns and the scientific evidence available to the
department?

(1)-(11) Yes. Works Approval W6167/2018/1 was granted on 25 January 2019. [See tabled paper no. #]
An appeal has been lodged against the conditions of the Works Approval and will be investigated by the Appeals Convenor, who will subsequently report to me. As the matter is under appeal and I will be the decision maker, it is not appropriate that I make further comment at this time.
