Introduction

Central Bedfordshire Council (CBC) is seeking planning permission to develop a Waste Park at Thorn Turn, north west of Houghton Regis. Figure 1 shows the location of the application site.

CBC has a responsibility to arrange for the disposal of any household waste collected within the Council boundary. It also needs to provide a place for the public to take their waste. These sites are known as Household Waste Recycling Centres, or more locally as ‘Tidy Tips’.

It is anticipated that the enabling works will begin in autumn 2015, with the main construction phase commencing in early 2016 for a period of 12 months. The initial enabling works will involve the construction of the site access road, the establishment of temporary office and welfare facilities.

Scope and Content of the Environmental Statement

The Environmental Impact Regulations sets out the types of development for which an

Environmental Impact Assessment should be carried out. The proposed development falls

under the regulations as a facility for the disposal of waste (2(11)). The outcomes of the

Environmental Impact Assessment are reported in the Environmental Statement (ES). The

2011 EIA Regulations provide details on what information the ES must contain.

The Site and Its Setting

The Waste Park at Thorn Turn, near Houghton Regis will comprise a waste transfer station (WTS), split level Household Waste Recycling Centre (HWRC) and resale shop together with a purpose built access road from Thorn Road.

Figure 1 shows the area of land to which this application relates. The closest settlements to the planning application site boundary are Houghton Regis (1.5km SE), Toddington (3.0km) and Tilsworth (2km NW) with the larger area of Dunstable being located 3km to the south east.

There are two statutory designated wildlife sites within 2km of the study area. The nearest is

the Houghton Regis Marl Lake Sites of Special Scientific Interest (SSSI) which is 470m from

the southern site boundary, and Totternhoe Chalk Quarry SSSI is located approximately

1.7km to the south-west of the site.

There are 5 non-statutory designated wildlife sites within 1km of the study area. The sites

include one Roadside Nature Reserve and 4 County Wildlife Sites. The application site is

currently used as agricultural land (Figure 2).

Figure 1 Site Location

Figure 2 Current site condition

Ouzel Brook flows in an east west direction on the northern boundary of the site. To the

north west of the site is an area currently used as a shooting range, beyond which is an area

of agricultural land, which runs to Thorn Road. The Dunstable Waste Water Treatment

Works is located to the east of the application site, beyond which lies arable farmland.

Immediately south of the application site is an area of vacant agricultural land. The A5

borders the site to the west, this lies between 9m and 12m above the proposed application

site, the road is separated by an embankment which is planted with mature woodland.

Committed Development within the Area

Consideration has been given to other planning applications and sites that have been granted planning permission in the local area. When taken with the proposed development, these sites could give rise to greater impacts on the local environment and this has been assessed through the planning application. Land immediately to the north and south of the application site will be the subject of two separate planning applications. A highways depot and salt storage barn (to allow for road gritting) is proposed on the land to the south of the application site. A new area of commercial development is proposed on the land to the north. The wider area also has a number of planning applications which are either being decided or have been decided, these relate to areas of proposed residential and other uses e.g. business, leisure and employment sites. Beyond these application sites, to the north of the application site is the A5-M1 link road scheme. This project has recently begun construction.

Description of the Proposals

Vehicle Access

A purpose built access road will be constructed from Thorn Road. Vehicles will travel down the access road, once over the Ouzel Brook, operational waste vehicles for the WTS will enter and leave the site via the northern access road which runs parallel to the brook. Vehicles will access via a weighbridge area with 2 No. weighbridges, one for waste vehicles coming into the site and one for vehicles leaving the site. Weighing the vehicles onto and off the site enables a calculation of the amount of waste each vehicle carries.

Waste Transfer Station

The WTS will consist of a large building for waste storage. The WTS building on the site will be made of steel walls and concrete flooring, the building will be clad with steel material coloured grey. It will be 102 metres in length and 36 metres in width. The building will be 11.8 metres tall to the top of the roof and 9 metres to the top of the walls.

The WTS will accept both residual waste and dry recyclate which is collected at the

kerbside. The total tonnage of material accepted in any one year is 98,000 tonnes.

On the southern side of the building, which opens out onto the outdoor operations area,

there will be 6 large roller shutter doors for the waste vehicles to enter and exit the building.

These will be closed whenever a waste vehicle is not driving in or out, to keep any dust,

odour or noise inside the building as so far as possible.

Vehicles will use the yard area to manoeuvre and will then reverse into the building. Refuse

collection vehicles and similar will access the building to offload the waste that they have

collected from the kerbside collections.

Material will be offloaded inside the vehicle. The waste will be tipped onto the WTS floor and

will then be pushed into one of the bays within the building using a loading shovel.

Once a sufficient quantity of material has built up within the bay it will then be moved off site.

Articulated wagons will be loaded inside the building before material is taken off site either to

a treatment facility for the residual waste or to reprocessors for the recyclate.

All waste loading and unloading will take place inside the building.

Motorised air vents in the roof will enable air circulation within the building and there will be a

misting system inside which will be used, if needed, to damp down the waste to reduce dust

and odour.

The receipt and removal of waste and outputs shall take place between the following hours,

however vehicles movements will generally be much reduced after 4.30pm and on Sundays

and Public Holidays.




9

The WTS will be open between 6.00am to 5.30pm Monday to Friday, 6.00am to 1.00pm on

Saturdays and 6.30am to 5.00pm on Sundays (requested receipt of bulky waste only,

normally closed). The facility will be closed on Christmas Day and New Year’s Day.

Outside of the building there will be two large tanks which store water for the firefighting sprinkler system and a pump room to pump water from the water storage tanks to the sprinkler system in case of a fire.

A Sustainable Drainage System will be in place at the site. Any water from the building roofs or off the pavement areas will drain to a surface attenuation pond to the north of the site. This will discharge at an agreed rate to the Ouzel Brook.

Any foul water e.g. from the buildings or trade effluent from the operational areas will be discharged to sewer. This will be pumped south down the site where it will join an existing Anglian Water manhole before being taken for treatment at the adjacent waste water treatment works.

The Waste Park will employ 15 members of operational staff.

Household Waste Recycling Centre

The HWRC will enable the general public to dispose of waste. The site will replace the existing HWRC at French’s Avenue, Dunstable. There will be also be a resale store, which will accept materials from householders which are suitable for reuse.

The HWRC will accept up to 7,721 tonnes of waste per year. This will be made up of

Residual (black bag) waste;

Glass;

Cardboard;

Green garden waste;

Plastics;

Wood;

Paper;

Metals;

Waste Electrical and Electronic Items;

Textiles;

Plasterboard; and

Household furniture including carpets.




10

The HWRC will be open to the public between 9.00am to 5.00pm Monday to Sunday 362 days a year. The facility will be closed on Christmas Day, Boxing Day and New Year’s Day.

Needs and Alternatives

Strategic alternatives

A wide ranging site search exercise was carried out for Bedfordshire County Council in 2005 to identify potential sites for an Integrated Waste Management Facility. The study was a two-stage process:

Stage 1 Appraisal’ of 95 potential sites which were compared against a number of

planning and environmental constraints; and

Stage 2 identification of ‘preferred waste sites’ for waste management.

The report concluded that the major constraint on the site identified in the initial site selection

of 2005 was that it was situated in the Green Belt. However, it went on to say that should

the Site continue to be promoted as a strategic waste site through the emerging Waste and

Minerals DPD, then this major constraints would be removed.

An update to the site search exercise was undertaken to support this application. This site search has re-assessed the 95 potential sites that were initially identified. As the initial assessment was carried out before the Councils in the area were devolved, sites in all three constituent Borough and District Council authority areas. For this application any sites located outside of the CBC administrative boundary were rejected.

The remaining alternative sites were then appraised against the following criteria:

Size;

Availability;

Ownership; and

Location.

The site search did not find any sites that could be taken forward as preferable to the Thorn

Turn site, that are also located within the appropriate area, or that meet the selection criteria

and are outside of the Green Belt.

Assessment of the Likely Environmental Effects

An assessment has been carried out to determine the likely significant effects on the environment of the construction and operation of the Waste Park.

Traffic and Transportation

Access to the site is from a purpose built access road. In order to understand the existing traffic flow, assessment of the conditions close to the site and traffic modelling was undertaken to calculate the likely impacts was also carried out.

All HGVs and vans associated with the construction of the store will be expected to enter

and leave the site via the main access which links to Thorn Road, as will HGVs delivering

RCBs to the store. Contractors’ personnel working on the construction will also utilise this

access.

A Transport Assessment was carried out to support the application. The modelling for this

assessment uses baseline traffic data and then considers how traffic levels are likely to

increase in the area over the next 11 years.

The findings of the submitted TA demonstrate that with the development fully occupied in the

growth year 2026, the site access junction would operate within capacity. It also shows that

the local highway routes are not expected to experience any capacity issues during the

operational phase of the proposed development.

There will be no significant effects from the predicted change in total traffic and HGV flows

during the construction or operation of the proposed development. The site lies in a

sustainable location and opportunities for sustainable travel have been used for mitigation

purposes. The local highway network will continue to operate within capacity in the growth

year 2031 with the development fully occupied.

Air Quality

This deals with the general air quality issues that may potentially arise, including dust and traffic generated emissions. An initial baseline survey was carried out through site visits. This also included testing the baseline odour levels in the area given the proximity of the waste water treatment works.

An assessment was carried out in line with relevant guidance of the potential dust generation and effects on PM10 concentrations. The following mitigation measures are proposed;

Production of a dust management plan;

All roads to be hard surfaced;

Vehicle loading and unloading will take place within the WTS building; and

Dust suppression system within the WTS.




13

Specific mitigation measures for the construction phase will include;

Sheeting vehicles carrying dusty materials to prevent materials being blown from the

vehicles whilst travelling;

Dampening down of surfaces prior to their being worked;

Storing dusty materials away from site boundaries; and

Not loading spoil into dump trucks from an excessive height.

The assessment identified that given the lack of human and ecological receptors within the

vicinity of the site boundary there are not anticipated to be any significant effects arising from

dust.

The potential effects from increased traffic movements has also been assessed. This

modelling demonstrated that concentrations of nitrogen dioxide, PM10 and PM2.5 will remain

below the strategic air quality objectives at all existing and proposed receptors in 2021. The

potential impact is therefore considered to be negligible.

Consideration of potential impacts on the local SSSI has been carried out. The results

showed that there are not predicted to be any significant impacts on the SSSI due to NOx

and nutrient and acid nitrogen deposition.

The assessment concludes that the overall operational air quality impacts of the proposed

Development are considered to be insignificant.

Noise and Vibration

The noise assessment has concluded that the potential impacts on local residents from

vehicle movements both in terms of the construction and operational phases will be

negligible.

During construction, the modelling demonstrates that there may be an effect in terms of

noise levels on the northern façade of the proposed extension to Chalk Hill Farm (which is

the nearest receptor), however given the use proposed for this side of the building (based on

planning submission), it is not considered to give rise to a significant impact.

During operations, the assessment shows that the noise impacts at the residential receptors

in proximity to the site would not be subject to significant impacts and there would be

negligible effects on these properties.

An assessment of the road traffic during both the construction and operation of the facility

also demonstrated that noise impacts are predicted to be negligible at all receptors.

Landscape and Visual Impact

A Landscape and Visual Impact Assessment has been undertaken in connection with the

proposed development. The LVIA considered the landscape resource, character and visual

amenity effects of the proposed development.




14

The assessment found that the long term impact of the proposed development on landscape

elements would not be significant and any existing vegetation that needs to be removed to

allow the construction of the development will be replaced.

It is considered that in the long term the majority of receptors will experience no adverse

effect on their visual amenity. There will be a greater impact on the views from the public

right of way, however planting along this edge will be retained and this will seek to limit direct

views into the site.

Ecology

An Ecological Impact Assessment has been undertaken. The assessment recognises that

there are areas of habitat on the site which do have conservation value, however the value is

not significant when considered on a wider scale.

As well as the loss of local habitats, the assessment highlighted that there is also potential

for a number of protected species to be affected, further surveys will be carried out to identify

the potential impacts. Mitigation measures will be employed as appropriate and the

assessment concluded that with such measures the impacts on the conservation status of

protected species can be avoided or reduced to a negligible level.

Compensation planting will be provided in the north of the Site in the form of additional

planting and seeding to create woodland as well as the development of species-rich

grassland habitats.

With the mitigation and compensation measures implemented, the EcIA concludes that no

residual impacts on ecological features are expected.

Water and Drainage

The site is underlain by the West Melbury Chalk Formation (Lower Chalk) which is classified by the Environment Agency as a Principal Aquifer. These are layers of rock that have high permeability, which means they usually provide a high level of water storage. The closest surface watercourse is located immediately to the north of the waste park (Ouzel Brook).

Flood maps for the site indicate that a proportion of the north end of the site is within Flood

Zone 3. This means that there is a 1% chance of the site flooding in any given year.

There is the potential for the construction and operation phases to impact on the water

quality in the area. However, it is considered that this potential risk can be managed by the

implementation of good practice and the development of a Construction Environmental

Management Plan (CEMP) which will seek to minimise potential impacts arising during the

construction phase. With appropriate mitigation, the assessment concludes that overall the

proposed development is not considered likely to result in significant adverse effect on the

water quality within the area.




15

The assessment concludes that there is only a low risk of flooding to the development from

Ouzel Brook, with flows contained within bank for the 1 in 100 year event and the proposed

Development will have no impact on the existing floodplain extents. There is a risk of

localised flooding from groundwater, however the site levels will be raised to minimise the

potential for this risk. Overall there are not considered to be any significant impacts to the

water quality or flood risk from the proposed development.

PROW

There is the potential that the public right of way which runs to the west of the site will be

affected by the proposed development in terms of visual impact and noise both during the

construction and development phases.

Design considerations have sought to ensure the buildings are sympathetic to the landscape

and perimeter landscaping will be retained where possible, particularly along the route of the

bridleway. To the north of the site, additional compensatory planting will be carried out.

A key aspect in regards to the bridleway is the potential for noise impacts, given the

proposed nature of the facility there may be loud sharp noises emanating from the facility.

Signs will be erected warning of this activity along the bridleway.

Summary and Conclusions

The impact assessment has sought to understand both the direct and indirect environmental effects of the waste park during the construction and operation phases.

Generally, the environmental impact assessment has determined that during the construction and demolition phase there will be some minor adverse effects relating to noise and landscape. However these all arise from short term impacts typical of activities on construction sites and mitigation measures will result in the development having no significant effects.

During the operational phase there is considered to be no likely significant effects from the proposed waste park.
