Scoping Report
Group 4
Summery

Keelin Timony, Yi Mao, Gefei Ma, Yamin Lu
1. Introduction
This group intend to submit an application for planning permission to Wicklow Local Council to operate a quarry for extraction of gravel.
This quarry is located at east shore of Pollaphuca Reservoir in the Wicklow hills (033 105 on OS land ranger sheet 56). The site location is shown on appendix.
The quarry company has appoint this group to undertake a scoping study and prepare this report for Wicklow Local Council to accept the scoping opinion of the planning application and if apply to Environment Statement (ES).
2. Quarry Location Site
The appendix shows the location of the quarry. The quarry is located at east shore of Pollaphuca Reservoir in Wicklow, approximate 5 km from Ballymore Eustace.
The nearest residential properties are located approximately 200 m to the west of the quarry.
The footpath of hiking is 200 m away from east and north side of quarry.
Description of quarry operation
The current method of extraction, blasting, dispatch have been established for years. The blast application is operating at upside of the slope and the blasted rock is loaded by truck and ship out of the site. The quarry operate for 4 years and during that time will provide full time employment for 20 people.  Approximately 4 truckloads of gravel will leave the quarry per working day.
3. Consultation and Participation Arrangement
There are several consultants and organizations in the list of appendix with the arrangement of communication schedule.
4. Potential impacts
4.1 Climate
Noise
During the quarry site construction and production, the aspects which will potentially enhance the noise impact level are as below,
*site preparation works, including the soil stripping, equipment installing, office and living condition constructing.
*mineral exploitation by explosive.
*mineral transportation by heavy vehicles.
*mineral processing operations by heavy machines.
All the potential noise impact above will take place at the target quarry immediately when the quarry project starts. The environmental baseline for the local area shall be determined by the existing Irish environment laws and regulations. Any activities concerned with the quarry preparation works and operation are limited to alter the existing status.The scope for any noise change is limited and for further consideration.
4.2 Air Quality (Dust)
During the quarry construction and production, total suspended particulate (TSP) is the main potential impact causing the deterioration of the local air quality. As TSP could spread by the function of wind or could deposit by the function of rain. It could impact on both human health and the biota significantly.
As the generation of dust exists in the whole course, the control of the baseline shall be mainly not only determined by the Irish environment laws and regulations, but also by the future reaction of the local people. The impact of dust could be cumulative.  Without efficient control, it could rise across the baseline level to cause significant complaints.
There shall be no additional dust sources from the exploitation, transportation and processing operations. All the activities will obey the principle and manner of achieving the maximum mitigation in the quarry construction and production.
4.3 Human
The development of this quarry is likely to cause a range of effects on human beings, which include social-economy, land use, human health and safety.
Social-economy
Although the location of this quarry just outside of Wicklow Mountains National Park, it also very closed to this park. Wicklow Mountains National Park has significant recreation and tourism appeal, and tourism industry is also the main economy in this area. Many visitors come from Dublin city to have a daily travel in there. Moreover, there is a club located near the quarry site.
Within this context, which may impact upon the enjoyment of leisure and recreation pursuits by visitors to the Park and customers to the club, e.g. impacts of demolition and construction, noise and vibration, traffic and transport, air and water pollutants and damage to the landscape, need to carefully considered. This impacts could include not only increasing noise and vibration, waste emission but also deterioration of landscape and road surfaces.
On the other hand, with this factory will provide 20 full time employments, it could improve job opportunities to local people. The quarry also can help improve the development of local construction industry.
Human health and safety
There will be 20 employment in quarry, meanwhile there also more than 10 local home surrounded this field. Within this context, some pollutants generated from transportation, operation and construction of factory, e.g. air, water, soil, and noisy pollutants, which will threatened human health and safety should also be investigated.     
Key issues
From above analysis, following likely significant effects of this project should be include within the EIA scoping. Generation of employment opportunity and improve local people’s income. Impact upon the enjoyment of leisure and recreation pursuits by visitors and customers. Pollutants generated from construction and operation which threatened local people and employees’ health and safety.
4.4 Landscape
The quarry and other accessary operations are long term establishments. Quarry will be approximately 500 x 200 m, the land and vegetation which will be destructed is scrub and meadow which is not private land or industrial land. This area is surrounding by streams, farms and houses. There are a road and a pedestrian around this area. The house and framing field is on the east side of the quarry spot. The long term of planning application is intend to maintain the woodland and wetland, also reduce the impact to the sightseeing loop in the Wicklow national park.
4.5 Soil & Blasting
The soil type in this area is chernozem, has a high agriculture capability. This area is fully covered with grass and bush. There are some wetland with moss. There are some huge rock stacked on the ground. It is easy to occur debris flow and water loss and soil erosion after the blast of quarry which results in ground vibration and dust. The blasting application will not present any vibration to the nature but to the reservoir, the vibration undertaken by blasting can be serious damage which need to be proof is harmless to the reservoir in the future. The aquifer in this area has enough distance from the surface, the quarrying application has not significant impact to the aquifer and groundwater.
4.6 Water and Flooding
Quarry for gravel extraction is working outdoor, and it also will have 20 employments working or living in there. Thus the Water pollution likely caused by the following sources: 
Discharge of untreated domestic, e.g. residences sewage by employments 
Workshop wastewater, e.g. wash off from exploding, drilling, excavation and loading and transportation.
Surface water
There is an east-west trend river pass through this area, and falls into the Pollaphuca Reservoir from the east. Thus the river is the main object in investigation about potential impacts on surface water.
The potential impact on the surface water quality from mining is likely to be due to higher load of suspended solids (SS).  The sources of suspended solids would from:
Gravels from the mine operations and wash off from machineries and soil waste.
Discharge of mine runoff during rains to the river;
Oil spillage from maintenance workshops
Oil effluent from residential colonies.
Groundwater
There is a reservoir near the study area, and the elevation difference between water table of reservoir and study room is 80 m. Generally, the water table level is similar with the level of reservoir which is seated surround. Therefore, if there are any aquifers under the study area, the likely of waste water seep cross soil and reach to groundwater is very rare.
Flooding
The Environment Agency’s flood maps indicates that there was a flood event happened with 86.1 rainfall on 24th October 2011, which located about 1500 meter in the northeast of quarry. Considering that it is not a recurring flooding point, and it also canbe found that the site of quarry is far away to another recurring flooding point, so it could be unnecessary to think about the flood risk in this area.
Physical, chemical and biotic sewage
The mean source of physical sewage from quarry operations, and the main pollutant is suspended solids (SS), which will pollute surface water. Moreover, the main source of chemical and biotic sewage is domestic sewage from staffs’ living in quarry, which include huge organic pollutants with high content of carbohydrate, nitrogen, phosphate and sulphur.  However, there are just 20 employments working in this quarry, so the impacts from discharge of residence sewage could be small.
Key issues
Effects from the domestic sewage discharged from quarry.
Effects on surface water physical quality from quarry operations.
Effects on the associated flood risk of surrounding water resource.
4.7 Flora and Fauna
The reservoir has been designated as a Special Protection Area under the European Union Directive on the Conservation of Wild Birds. The reservoirs Graylag goose population is of international importance. Present at the reservoir in spring time and migrate south to warmer locations during the winter time. Compaction by heavy machinery may impact flora and fauna.
5. Biological Sampling
Two streams run through the proposed quarry site towards the Pollaphuca Reservoir. The Environmental Impact Assessment (EIA) will carry out a biological sampling program to investigate the status of the streams in terms of freshwater invertebrate populations prior to the opening of the quarry. This baseline study will function as a control from which to compare future monitoring measurements. The EIA will also suggest a monitoring program to be put in place once the quarry has been opened so that it can be determined whether the quarry operations are having a negative impact on freshwater invertebrate.
The biota to be sampled is the freshwater invertebrates in the streams. The baseline study will establish which species or taxa are present in the streams and their abundance. The baseline study will calculate a Quality-index score for the streams using the EPA Quality Classification system. This indicates the pollution level of the stream and is calculated using macro invertebrate diversity data. The study will make note of whether there are taxa that are known to be pollution sensitive present. These taxa could then be used as indicator species to inform of pollution of the stream during the monitoring stage. Ephemoptera (Mayflies), Plectoptera (Stoneflies), and Trichoptera (Caddis flies) are commonly used as pollution indicators in freshwater streams as they are known to be sensitive to pollution. The baseline study will also establish whether there are any rare or protected species to be found in the stream.
The sampling sites will be at a number of locations along the streams as marked by the stars on the map below. Both baseline studies and monitoring samples will be taken at the same sites. The sites chosen have a riffled section of stream. These are chosen because they are more likely to contain pollution-sensitive macro invertebrates due to the higher oxygen content. Sampling will be done daily for 5 days in each of the four seasons to obtain a holistic picture of invertebrate populations and allow for seasonal variation.

The method used to obtain samples from the streams will be kick sampling. The invertebrates will be identified to taxa or species level in the lab using keys. This specialist work may be carried out by a chartered ecologist. The data will then be analyzed. The same team will carry out all of the sampling program following standard methods to ensure results are comparable. The standard amount of sampling time and size of net mesh will be used.
Prior to beginning the main sampling program a pilot study will be carried out to ensure that the sites chosen are safe for kick sampling and to finalize protocol. The pilot study will also be used to measure natural variation and thus inform how many samples should be taken.
The sites used for monitoring will be same as those used for the baseline study as mentioned above because these are not directly involved in the development. Beyond BACI (Before-After, Control-Impact) methods with multiple control sites will be used to minimize misinterpretation of coincidences.
