    1.1 Company History

    The Company was originally incorporated as Ambrosia (Ireland) Limited in 1966 and it commenced production of Skim Milk Concentrate in April 1971. Later that year it was taken over by Express Foods Group Ireland and its name was changed to Virginia Milk Products Limited (VMP).

    At this time, the boilerhouse was run on heavy fuel oil and the effluent treatment plant consisted of the existing balance tank and the sludge thickener (operated as activated sludge tank and clarifier). In 1972 the first spray drier was installed and skim milk powder was produced. Plant throughput was in the region of 6 million gallons of whole milk per year. In 1973 another evaporator and spray drier were installed to handle increasing milk supplies.

    Until 1976, the main products were skim milk powder and whole milk powder, with excess cream sold to Killeshandra Co-op for butter making. That same year, a cream base production unit was installed to supply cream base to Gilbeys of Ireland Ltd. for the manufacture of Baileys Original Irish Cream. Due to increasing milk supplies, there was a major plant refurbishment in 1982. The spray drier was revamped, a new evaporator installed and the effluent treatment plant was changed to its existing format, i.e. almost doubled in capacity to handle increasing milk supplies. That year, due to the increase in oil prices, the boilers were also changed to burn coal.

    In 1988, Virginia Milk Products Ltd. bought the Millac brand name of fat filled milk powders and production of same commenced. This was the first time that powders were sold outside of An Bord Bainne. In 1991, milk throughput had risen to a maximum of 57 million gallons of whole milk. That year, it was decided to convert the boilers to handle natural gas from the national grid and oil was used in the interim period (until 1992). Accreditation to ISO 9002 was also gained that year. In 1992, Virginia Milk Products Ltd. was taken over by Waterford Foods Plc. who in 1997 merged with Avonmore to form the Avonmore Waterford Group. In 1999 the company name changed to Glanbia PLC and VMP is now officially incorporated as Glanbia Ingredients, (Virginia) Limited. In 1998 and 1999 the small drier was “revamped” in order to facilitate the production of Fat Filled Milk Powder and a baghouse filter was installed to ensure stack emissions minimised.

    Today, the product range is as follows:

    � Cream for Baileys Original Irish Cream liqueurs. � Instant and non instant fat filled milk powders. � Skim milk powders.

    1.3 Manufacturing Outline

    The milk processing facility may be further divided by product type into unit operations which include:

    � Milk intake. Whole milk & skim milk is received by road tanker at a

    maximum rate of approximately 1,00 per day. Approximately 367726 m3 of milk was processed on the Virginia site during 2008.

    � Separation Plant. Whole milk is pumped from the Milk Intake storage area

    and processes in one of two separation lines. The cream fraction is separated off pasteurised, cooled and stored awaiting dispatch to Baileys for use as the cream base in Baileys Liquor. The skim milk fraction is stored before being processed in the Evaporation Plant.

    � Evaporator Plant There are three Evaporator Plants on site, Lag 1, Lag 2 &

    the Wiegand. Lag 2 processes the majority of the skim, Lag 1 is used during peak demand and as backup. The Wiegand is rarely used. Skim milk is processed in the evaporator plant to raise the solids percentage giving a concentrate milk product with approximately 40 percent milk solids.

    � Powder Dryers. There are two powder dryers on site. Anhydro 1 was

    installed in 1999 & Anhydro 2 was installed in 1972. Both dryers are operating continuously throughout the year. The FFMP (Fat Filled Milk Powder) product is a combination of SMP, Vegetable Fat(s) and Vitamins to customers’ specifications. Approximately 47,214 tonnes of FFMP was manufactured during 2008.

    Monitoring data for the period January 01st to December 31st, 2008 is summarised in Table 2 for monitoring point reference EF7 and Table 3 for monitoring point reference EF6, as annual mass emissions. The annual mass emission for each parameter is based on the average analytical result for that parameter (mg/l) as massed up by total actual volume of effluent in the reporting period. The permitted licence emission is based on the emission limit value for each parameter multiplied by the permitted maximum daily flow taking 365 days per year operation. A comparison of the surface water monitoring results between 2004 and 2008 for EF7 are noted in Table 3 and illustrated in Figure 3.

    NCR 1 Condition 11.4

    The licensee was unable to readily retrieve up to date monitoring data in relation to the WWTP operational control and emissions to water. Also it was unclear as to the trigger levels in relation to diversion of condensate to the WWTP, as required under Condition 6.5. In this regard the licensee was unable to retrieve to relevant standard operating procedure.

    Report to the Agency on the system in place to allow diversion of condensate to the WWTP and the related trigger levels required under Condition 6.4 and 6.5. Put in place procedures to ensure that up to date monitoring data and standard operating procedures are available for inspection, in paper format, at all reasonable times.

    Glanbia Virginia will ensure that monitoring of data related to the WWTP will be printed out at the end of each month and held in a folder in the Environmental Manager’s Office. The diversion of condensate is controlled by the Honeywell SCADA system. The set point for conductivity is 100 µS/cm until below 90 µS/cm to divert to the effluent plant. The set point of the temperature is set at 25 DegC taken at the final effluent outfall from the plant. The temperature and conductivity control system at the plant ensures that no high temperature or high conductivity condensate comes off the plant. This feeds back to the condensate diversion system in the process which switches to effluent line, should these conditions transpire.

    OBS 1 N/A Runoff from the Car Park There was visual evidence of car washing activity in the above car park, and the licensee was unable to demonstrate that drainage from this area was diverted to the WWTP.

    Submit detailed scaled drawings showing the site drainage system, and put in place measures as necessary to ensure that waste water from all washing activities is diverted to the WWTP.

    Glanbia Virginia is investigating measures to ensure that runoff from this facility is diverted to the WWTP. Detailed scaled drawings will be submitted in due course.

    OBS 2 N/A Accumulation of dust adjacent Air Emission Point A2-2

    OBS 3 N/A Location of sampling ports on Emission Point A2-2 Contractors engaged by the EPA to carry our dust monitoring at the above emission point have raised concerns about the location of the sampling ports on the above stack. In particular, the proximity of the ports to a structural support beam within the stack poses practical difficulties in terms of handling monitoring equipment and ensuring that samples obtained are representative.

    It was agreed on site that the licensee would consult the suppliers of the stack with a view to relocating the ports if possible, and report to the Agency on same.

    Glanbia Ingredients Virginia will consult the supplier of the stack A2-2 with a view to relocating the ports if practicable and report to the agency when possible.

    9 Schedule of Environmental Objectives and Targets

    This section contains a brief summary of the progress in meeting targets established under the Environmental Management Programme 20087 - 2009, details of which were submitted as part of the last AER.

    9.1 Environmental Management Proposal 2007

    The objectives that were set for 2008 encompass four key areas identified as having scope for or scope for environmental improvement. The objectives focus on waste reduction, Energy saving, noise reduction and Water recovery.

    2006:01 Reductions in quantity of waste to landfill

    Target/Objective The reduction of waste to landfill, through achievable

    targets, continued control and monitoring of waste streams.

    9.1.1.1.1 Reason To increase the proportion of waste recycled and comply with waste management regulations. To act in accordance with section five of the Glanbia Virginia Environmental policy

    Aim It is the intention of Glanbia Virginia to reduce the amount of waste sent to landfill by setting a target of three percentage reduction over the next three years. This objective is an extension of previous targets set to continuously reduce, reuse and recycle waste generated on site. Certain waste streams will be targeted, like office paper and waste paper packaging produced on site. These waste streams currently go to landfill at a cost to Glanbia Virginia and the environment. However it is the intention of Glanbia Virginia to redirect this waste towards recycling centres, where possible.

    Methods Sourcing of new waste outlets, by quantifying the amounts of waste to be recycled. Then through contacting waste recycling agents and contracting them to manage this waste in a sustainable and responsible manner.

    Priority Medium Time Frame 2004-2009 Responsible Person

    Environmental and Service Manager, Waste contractors, Glanbia Virginia Personnel

    Monitoring Method Incorporated into AER

    Status The landfill objective is on-going and a target of 3% reduction is still in place. The 2008 landfill figure is 115% above the 2007 figure, which is due to changes in disposal times and increased vigilance in hygiene.

A copy of the 2009 EMP objectives and targets including timeframes are outlined in Attachment C of the report.

    10 Pollution Emission Register

    The pollution emission register for 2008 tracked inputs of phosphorus on site in the form of milk processed on site. A concentration of 970 mg/l Total Phosphorus was calculated as the concentration of Phosphorus in skim milk (i.e. 0.097% w/w). A total of 367,726m3 skim milk (equivalent) was processed during 2008, giving a total phosphorus input of 356694.2 tonnes. Dried Fat Filled Milk Powder is made up of 67% skim milk powder, 30.5% Fat and 2.5% moisture. The Phosphorus content of FFMP is 0.68% w/w; the total production of FFMP in 2008 was 47,214 Therefore total 321055t phosphorus left as finished powder product. From sludge analysis undertaken in the past, the phosphorus content of sludge spread on approved land is approximately 1.76mg/g or 0.176% w/w. 1443 tonnes of sludge was spread on lands during 2008 giving a figure of 2.522 tonnes of Phosphorus accounted for in bio sludge. In 2008 an approximate total of 199kg Phosphorus was discharged in treated effluent. Based on the mass balance, the unaccounted proportion of phosphorus amounts to approximately 9% of the total input.

    1. INTRODUCTION

    This report by Pascal Sweeney, Consultant Environmental Biologist, presents the results of the

    2008 sampling of Lough Ramor and is part of an ongoing monitoring programme of the lake,

    commissioned by Glanbia plc. This is the seventh year of the sampling programme, the purpose

    of which is the assessment of biological impacts of the discharge from the Glanbia plant to

    Lough Ramor by the monitoring of changes in benthic macroinvertebrate communities.

    In studies of lake ecology, elements within communities of benthic macroinvertebrates (the

    larger and more readily visible invertebrate animals which colonise the lake bottom) have been

    shown to respond to variations in factors associated with nutrient levels (e.g. Parrish and Wilhm,

    1978; Moore, 1980; Reynoldson et al., 2000; Irvine et al., 2001; Milbrink et al, 2002). Such

    changes in macroinvertebrate communities have been used to assess changing condition of lakes

    over long time periods (e.g. Nepala, 1991; Nepala et al., 1998; Hall et al., 1999; Lozano et al.,

    2001). In studies of lake macroinvertebrates, assessment of change in response to nutrient levels

    has been more successful in deeper muddier sediments (sub-littoral and profundal) than in the

    shallow littoral zone (Rasmussen and Kalff, 1987). The present monitoring programme of

    Lough Ramor therefore focuses on changes in the macroinvertebrate fauna of the muddy

    offshore sediments in proximity to the treated effluent outfall.

    As benthic surveys of Lough Ramor, carried out by Natural Environment Consultants in the

    1990s, showed that the local impact of the effluent was confined to a zone of less than 100m

    from the discharge point, two sampling sites were established for the current monitoring

    programme, one close to the treated effluent outfall and a second c. 150m away (Map 1). Both

    sites are at a depth of c. 3.25m and are of similar substrate type, with soft mud and fine plant

    debris. The site co-ordinates are:

    Site 1 Grid Reference: N6233 8508

    Site 2 Grid Reference: N6241 8496

  • 4

    Changes in the benthic macroinvertebrate fauna at Site 2 can therefore be regarded as reflecting

    the general condition of the lake, while the fauna at Site 1 is also influenced by the quality of the

    effluent discharge.

    Possible seasonal variation must be taken into account when monitoring benthic

    macroinvertebrate populations (Jackson and Resh, 1998). Reid et al. (1995) found that

    collections of macroinvertebrates are highly repeatable if sampling is restricted to periods of not

    more than three weeks. For this survey, the sampling of Lough Ramor is carried out in the last

    week of June or the first week of July each year,

    2. METHODOLOGY

    2.1 Sampling Procedures Field work was carried out on 2 July, 2008. Quantitative sampling was carried out, with ten

    replicates taken at each site, using a 6cm diameter Maitland core sampler (Maitland, 1969).

    Samples were preserved with formalin in the field.

    2.2 Laboratory Procedures Samples were sieved through a 0.5mm mesh. All macroinvertebrates were removed by hand-

    sorting, preserved in 70% alcohol and were identified using a high-power microscope. To

    maximise the usefulness of the data, invertebrates were identified to the lowest taxon practicable.

    Oligochaeta (segmented worms) were identified using the FBA identification guide for British

    species by Brinkhurst (1971) and a guide to European species by Timm (1999). Chironomidae

    (non-biting midge larvae) were identified using the identification keys edited by Wiederholm

    (1983).

    The preserved samples were retained and stored in vials of alcohol so that they may be checked,

    if necessary, in the future.

    2.3 Data analysis At each site, the mean number of individuals of each species per m² was calculated.

    The total number of individuals of taxa described by Irvine et al (2001) as indicators of

    enrichment (Limnodrilus sp. + Potamothrix/Tubifex grp. + Chironomus sp. + Procladius sp.) was

    found and their percentage representation in the total fauna was calculated.

    The Quirke Index 1 was also calculated. This index is calculated as log abundance (Limnodrilus

    group + Potamothrix/Tubifex grp. + 0.1 Chironomus spp.). Of published profundal invertebrate

    indices of lake trophic status, this index was found by Free et al. (2006) to have the best

    correlation with total phosphorus across 201 Irish lakes.

    3 RESULTS

    3.1 Macroinvertebrate Communities Table 1 gives the mean number of individuals of each macroinvertebrate taxon per m² (to the

    nearest whole number). In order to avoid the creation of spurious additional taxa which would

    affect these calculations, oligochaete species which can only be identified when mature are

    included with immature individuals of the higher taxonomic group. The presence of mature

    specimens is noted in sub-section 3.2.
