IF smoke from tyre burning at Westbury is supposed to disperse way above us and be 'safe', how come I've smelt strong burning rubber many, many times on Salisbury Plain and nearby villages of West Lavington, Cheveril, Marston, Worton, Erlestoke, Edington, Potterne, Poulshot, Tinhead, Market Lavington, Easterton, Urchfont, Seend, Bulkington, Bratton and Keevil.

I'm not alone in wanting to breathe clean air, not this disgusting muck.

CONGRATULATIONS on the new emission levels set for the Blue Circle Cement Company in Westbury are premature. I'm sorry to say it is mainly spin.

Not one new filter has been fitted and none is on the immediate horizon. What have we waited 18 months for? A PPC review that left the company to do the work which the Environment Agency rubber stamped.

As part of this review they should have conducted BAT assessments, these were so important as the money the company receive for burning tyres of £40 per tonne, should provide an economic calculation about what filters could be offset against this income. It was left to the company to do and the decision document does not address this issue at all.

What have the agency done? Well they tightened up the standards which were too lax before. This does not mean things have got better only the standards we brought down to the data that is being produced now on emissions, but the company have been given nine months to come up with an action report on how they can improve their environmental performance.

We were promised scientific justification in this decision document. What we got, yet again bland statements that "We have looked at this issue and believe the current regulation is sufficient!" Therefore no peer review of how they came to their decisions.

This agency is cornered by its previous regulation history and in my opinion they are producing reports which are indefensible. However they have the power to get away with it.
