Following on from the Leziate meeting, I have been making enquiries as to what air quality testing has been done locally. I have not read the reports in detail yet, though I thought it would be a good idea to leave the correspondence within this article so that you can make your own judgements. Thanks to all those people who have responded in a timely fashion to my requests.
The bottom line is that there is no air quality testing currently being done at any of WBB's quarry sites to my knowledge, unless WBB can confirm otherwise.
Answers already received by Councillor Alistair Beales from questions put via Leziate residents:
Neil – regarding point 1) the Borough Council of Kings Lynn and West Norfolk is responsible for air quality – specifically Environmental Health. Points 2-5 are covered below. Most of the following is from answers I have already received from questions put via Leziate residents. As follows:
“The Leziate site was considered for emissions of fine particles called PM10 in 2000 which included an Air Quality Monitoring Station being located in the area to measure dust levels and air dispersion modeling was also carried out. The levels of PM10 were below the action limit. The site is also regulated as a Part P Permitted Installation and has conditions controlling emissions of dust.
The Reports are available on line: -

http://www.west-norfolk.gov.uk/Default.aspx?page=21848
The Environmental health officer concerned is not aware of any dust complaints from local residents.”
General comments were as follows:
“Dust can be controlled from the extraction site by planning conditions, statutory nuisance and if needed Air Quality Management Area.
Using DEFRA guidance we look more closely if residential dwellings are within 200m, if so then this may lead to exposure to PM10, but this does not mean that the level of dust that would cause harm. Also being rural there may be other sources of PM10 locally meaning that the background level of PM10 is naturally high.
We will make general comments on each site, but until a detailed planning application is submitted it is difficult to determine the exact impact to local residents. Certain issues can be mitigated by the use of conditions etc and until we know what they want to do and how they plan to do it then the impact cannot be fully anticipated.
Dust is controlled from the processing site by Part B permit and if needed Air Quality Management Area.
The main health issue is inhalation of PM10 (fine dust particles). This type of extraction will lead to some dust emissions but as the extraction is below ground level and the material is usually damp, emissions are minimized. However, I have found that the haul route and transportation links can also lead to dust emissions.”

In summary, yes we have monitored around the WBB Minerals site at Leziate and also carried out air dispersion modeling. This work indicated that there were not any likely breaches of the National Air Quality Standards levels for fine dust (PM10). There are two levels to be considered an annual mean of 40 ug/m3 and a 24 hour mean of 50 um/m3 which must not be exceeded more than 35 times in 12 months. We consider that the levels of dust at nearby residential dwellings, workers or occupational exposure of dust would fall to the Health & Safety Executive remit.
You can read the details in the Air Quality reports which are published on the Council’s website.

Dear Mr Paddock
Thank you for your email.
The Environmental Health Officer has a statutory duty under the Environment Act 1995 to monitor air quality. In this case the relevant contact is David Robson dave.robson@west-norfolk.gov.uk at King's Lynn and West Norfolk Borough Council.
The County Council as Mineral Planning Authority, when granting planning permission for minerals developments, imposes planning conditions. These cover a range of matters including control of potential impacts on local amenity which may arise from, for example, noise, odour, and dust and sand blow. In the case of the permission for the WBB Minerals Grandcourt Farm quarry there is a condition, number 7, as follows: measures shall be taken to minimise dust nuisance and sand blow caused by the operations, including spraying of road surfaces, plant area and stockpiles.
The Environmental Health Officer was a consultee on the application, and his response was referred to in the report to the County Planning (Regulatory) Committee. He does not need to attend these committee meetings.
The County Council has a Monitoring and Controlteam which inspects minerals (and waste)sites regularly, and in addition to that, in the event of complaints being received. The WBB Minerals operations in Norfolk have generated very few complaints over many years. Mark Potter is one of the Monitoring officers, and he is familiar with the site and activities on it.
Regards
Rob Cranthorne

Thanks for taking time out to meet with me last week
A couple of quick questions for you
Following on from our conversation about air quality, I feel that something needs to be put in place as a matter of urgency
Driving back from the sailing club there is a huge pile of sand at WBB’s King’s Lynn Quarry, which could be generating wind blown dust particles and blowing them across the whole village and beyond.
Would you please be able to make enquiries on our behalf and establish:
1) Who is responsible for air quality testing locally
2) What air quality testing (if any) has been done in or around the silica sand quarry sites, at Ashwicken and East Winch
3) How often it is done
4) What actual readings have been taken, and
5) Whether or not those readings confirm that the air quality locally is satisfactory
PS Heather Bolt suggested it was Mark Potter who I assume works for NCC, though I would be interested in establishing the identity of the local environmental health inspector, in particular, the one who was present at the planning application meeting for the land to the West of Grandcourt Farm, Middleton, when planning permission was granted on 7/9/07
Please advise if you can be of assistance
