Contaminated Land
- Mulroy Environmental managed a
Phase II Site Investigation/Risk Assessment & Remedial Plan of a
Petrol Retail Station located in County Westmeath. The investigation
works involved drilling 8 boreholes using a Bobcat Window Sampler to
assess the degree of contamination of the overburden and the underlying
groundwater. Six of these boreholes were installed with groundwater
piezometers for groundwater sampling. Residual contamination and a minor
groundwater plume were identified on site. The RBCA Model Toolkit
Version 2 was utilised to assess the risk to site operatives and an
adjacent surface water body. This will be remediated in 2009 by
excavation of approximately 500 tonnes of the contaminated material and
transfer to a Hazardous Waste Facility (download keynote project summary sheet).
- Mulroy Environmental managed the compliance with a Section 55 Notice which was issued by Louth C.C. on the 17th
July, 2006 regarding a Brownfield Site located in North Drogheda. This
land is owned by a client who wishes to develop the property for
commercial and industrial usage. The site was originally the location of
a limestone quarry which following its end of life was used for the
landfilling of domestic waste and inert rubble. Following a risk
assessment by a previous consultant, recommendations were made with
regard to the safe development of the site (download keynote project summary sheet).
- Mulroy Environmental managed a
Phase II Site Investigation/Risk Assessment & Remedial Plan of a
Petrol Retail Station located in County Offaly. The investigation works
involved drilling 6 boreholes using a Bobcat Window Sampler to assess
the degree of contamination of the overburden and the underlying
groundwater. These boreholes were installed with groundwater piezometers
for groundwater sampling. A public water abstraction borehole is
located to the east of the site with the subject site being within the
outer source protection zone. This was remediated by excavation of
approximately 1,700 tonnes of the contaminated material and transfer to a
Hazardous Waste Facility. In order to determine the impact of
historical activities on the underlying aquifer a groundwater monitoring
borehole was installed to 46m (i.e. 29m into bedrock) and sampled. The
site was remediated successfully and is now being developed into a
modern petrol retail site with accompanying shop and restaurants (download keynote project summary sheet).
- Managed the compliance with a
Section 55 Notice which was issued by Louth C.C. regarding a Brownfield
site in Dundalk. The site was originally the location of a limestone
quarry which following its end of life was used for the landfilling of
domestic waste and inert rubble (download keynote project summary sheet).
Waste Licensing & Permitting
- Mulroy Environmental managed the
processing of a successful Waste Permit application for the remediation
of a contaminated historical landfill. This site which was formerly
a quarry was landfilled over a period of 30 years causing groundwater
contamination on site. The project will involve the excavation of
approximately 14,000m3 of waste consisting of a mixture of
construction and demolition waste and domestic waste. C & D waste
will be processed on site using a trommel, crusher and screen and
recycled as construction fill material. This material will be assessed
for its geotechnical properties to ensure compliance with current NRA
standards. The fines segregated by the C & D process will be sampled
for laboratory analysis and assessed for contamination and its
subsequent suitability for use on site. All municipal waste will be
segregated and transferred to a municipal landfill. Hazardous waste will
be transferred to a Waste Licensed Facility (download keynote project summary sheet).
- Mulroy Environmental managed a
successful Waste Permit Application for an ‘End-of-Life Vehicle’
Recycling Plant which will de-pollute cars in a dedicated de-pollution
area on site prior to transfer to another End-of-Life Vehicle Recycling
Plant. This site is in a heavily industrialised area and as part of this
work 2 dedicated groundwater monitoring wells were installed on site to
assess groundwater pollution from on-site and off-site activities (download keynote project summary sheet).
- Managed the successful application
for a waste permit on behalf of Aranmount Ltd. (the client) for an
infill/reclamation of a 4.1-hectare site which is located at
Drummeenagh, Castlebellingham, County Louth. The site will be infilled
by raising the site an average of 1m over its present height and that
this 1m of fill would be made up of 0.75m subsoil and a minimum of 0.25m
of topsoil. Given a surface area for infilling of 30,369m2, it is estimated that approximately 60,738 tonnes of soil will be required (download keynote project summary sheet).
On-site Wastewater Treatment
- Mulroy Environmental managed the
processing of a successful Discharge Licence Application for a 19-house
residential development in Ballindaggin, Enniscorthy, Co. Wexford. This
Discharge Licence Application involves the treatment of wastewater by
Submerged Membrane Bioreactor followed by a stratified sand polishing
filter after which the treated effluent is discharged to groundwater. A
groundwater assessment involving the installation of 2 groundwater
monitoring boreholes, pump testing of each borehole and qualitative
monitoring was carried out. Planning permission was obtained for this
development (download keynote project summary sheet).
Water Abstraction Surveys
- Managed the processing of Water
Abstraction Surveys for a 19-house and a 25-house residential and
commercial development in Ballindaggin, Enniscorthy, Co. Wexford. A
borehole was drilled on each site followed by a 72-hour pumping test and
groundwater quality monitoring. A yield of 250 gallons/hour and 300
gallons/hour were achieved for the 19-house and 40-house residential
developments respectively. Planning permission was obtained for the
19-house development (download keynote project summary sheet).
- Mulroy Environmental managed the
processing of Water Abstraction Surveys for a 14-house and a 30-house
residential development in Kilcurry and Faughart, Dundalk, Co. Louth
respectively. Boreholes were drilled on each site followed by 7-day
pumping tests and groundwater quality monitoring. A yield of 416
gallons/hour and 1200 gallons/hour were achieved for the 30-house and
14-house residential developments respectively. Planning permission was
obtained for the 14-house development in Kilcurry (download keynote project summary sheet).
Expert Witness
- Padraic
Mulroy of Mulroy Environmental acted as an expert witness and provided
consultancy to a client who was subject to circuit court proceedings by
Louth C.C. regarding the suspected illegal deposition of waste on his
farmstead without a waste permit. A site investigation was carried out
on behalf of the client following which a Risk Assessment Report was
produced by Mulroy Environmental. This report was taken as evidence in
court session at Ardee District Court.
- Mulroy Environmental provided
consultancy to the Toome Anti-Power Plant Residential Group and acted as
an expert witness at the An Bord Pleanála Oral Hearing which was held
in the Nuremore Hotel, Carrickmacross, County Monaghan on the 20th
March, 2008. The planning application and environmental impact
statement for the proposed power plant were prepared by the Quinn Group.
The planning application for the proposed 450MW Power Plant was
submitted directly to ABP under the Strategic Infrastructure Development
Act, 2006. This work required the review of the soil and water sections
of an Environmental Impact Statement prepared for the proposed power
plant.
Statutory Applications
- Mulroy Environmental supervised an
ecological assessment to be carried out as part of an external review of
SAC designation on a site located in the townland of Cloghaunamallagt
located to the southwest of Oranmore, Co. Galway. The survey site is
currently designated as a Special Area of Conservation (SAC No. 0268).
The survey work was carried out by Claire Deasy, MRes. (Marine Science);
BSc (Applied Ecology). Overall project supervision was provided by
Mulroy Environmental.
