Mr. George Howarth: To ask the Deputy Prime Minister what proposals he has to change the regulations on industrial formaldehyde emissions in the light of HSE advice on the levels of concentration at which strong odours occur. [68354] Mr. Meacher: I have been asked to reply. Risks to worker health from formaldehyde are already addressed by the Control of Substances Hazardous to Health Regulations 1999 (COSHH). The Health and Safety Commission has approved Maximum Exposure Limits (MELs) for formaldehyde at 2 ppm (parts per million by volume) as an 8-hour time-weighted average, and 2 ppm as a short-term limit with a 15-minute reference period. Under COSHH, exposure by inhalation to a substance with a maximum exposure limit must be reduced as far as is reasonably practicable, and in any case below the MEL. In its documentation summarising the criteria for setting MELs, the Health and Safety Executive (HSE) states that formaldehyde has a threshold of detection by smell at around 0.8 ppm. An earlier HSE Toxicity Review notes that the threshold for odour detection varies among individuals, with values in the range 0.05-1 ppm having been reported; it is expected that all would detect the odour at the latter value. HSE has issued no further advice relating odour to concentration; it does not normally seek to offer advice on odour problems. Industrial formaldehyde emissions to the wider environment are currently regulated by local authorities or, where larger industrial processes are concerned, by the Environment Agency, under the provisions of the Environment Protection Act 1990. Each industrial process requires an authorisation from the regulator. Where formaldehyde emissions are likely to cause environmental harm, each authorisation will contain conditions designed to limit its release. The regulator may at any time vary those conditions if it considers that necessary. The regulatory system established by the 1990 Act is gradually being replaced--from now to mid-2007--by that set out in the Pollution Prevention and Control (England and Wales) Regulations 2000. Each industrial installation will require a permit, which must contain conditions relating to formaldehyde emissions if these are likely to be significant to human health or human senses, or to impair or interfere with amenities and other legitimate uses of the environment.
