1. Introduction

Introduction

1.1 Licence Register Number This Annual Environmental Report for Platin Cement Works is issued to comply with Condition 2.2.2 of IPPC Licence No. P0030-04 issued by the Environmental Protection Agency in January 2011. The Report summarises the environmental performance of Platin Cement Works for 2012. The Report also reviews the 2012/2013 Environmental Management Plan and outlines the 2013/2014 Environmental Management Plan. The Report indicates ongoing compliance with IPPC Licence No. P0030-04. 1.2 Name and Location of Site Irish Cement Limited, Platin Works is situated in Platin, Drogheda, Co. Meath. 1.3 Brief Description of Activities at the Site Irish Cement Limited, Platin Works manufactures cement from raw materials. This involves quarrying, crushing, milling and heating processes as well as transport. This gives rise to associated noise and particulate emissions, as well as other atmospheric emissions, water emissions and various types of waste.

1.4 Company Sustainability Policy

Irish Cement is committed to providing cement products for use in construction which are sustainable. To this end we have developed a Responsible Sourcing Policy in accordance with the requirements of the BRE Environmental and Sustainability Standard BES 6001.

This standard has been prepared by BRE to provide a framework for the assessment of responsible sourcing and to give a route to certification of construction products.

The requirements of the standard include that we measure, monitor, verify and report on our sustainability performance across a wide range of parameters including:

Health & Safety Management Quality Management Environmental Management Supply Chain Management & Material traceability

All of these aspects of our sustainability performance are now available via the links on this website.

Irish Cement has already integrated an ISO14001 accredited Environmental Management System and an ISO9001 accredited Quality Management System into our day-to-day operations in order to continually improve, attain and maintain the highest standards of performance.

We are very proud to now announce that we have further enhanced these Management Systems by becoming the first company in the Republic Of Ireland to attain accreditation to the BES6001 standard for our Eco-efficient CEM II products. In the true spirit of balanced sustainable development the BES6001 standard requires that measurable and verifiable performance improvements under all three of the pillars of sustainability (Environmental, Societal, and Economic) must be addressed rather than just focus on any one aspect to the detriment of any other. The introduction of this certification ensures that the broader sustainable development aspects are integrated into all business decisions.

1.5 Company Environmental Policy

Irish Cement Limited recognises the environmental responsibilities associated with all the aspects of its operations and as a matter of policy seeks to avoid, reduce and mitigate any potentially adverse effects on the environment.

The Company is committed to the integration of environmental considerations into decisions making at all levels of the organisation.

It is Company policy to comply with all legal requirements imposed on its operations and in particular to operate its production facilities at Platin, Co. Meath and Castlemungret, Co. Limerick in accordance with the requirements of the Integrated Pollution Control Licences issued by the Environmental Protection Agency.

Minimising the environmental impact of emissions Conserving mineral and energy resources Minimising waste generation Minimising water consumption Reducing the visual impact of its operations Reducing the adverse impact of transportation Responsible sourcing of supply materials

The Company seeks to exist as a good neighbour to those living close to its plants and has adopted a policy of open communication on environmental performance.

In order to demonstrate its commitment to the highest level of environmental management Irish Cement Limited has adopted the environmental standard ISO 14001:2004.

Did not run during these months

Kiln 2 was started at 23.30 on the 3rd Dec. At 01.00 the kiln was operating steadily. Feed to the kiln was then lost for 3 – 4 minutes. This resulted in process instability which led to a rise in NOx levels. Attempts were made to stabilise the kiln and as a result there was a period where the half hourly NOx

limit of 1000 mg/m3 was exceeded. The kiln was then stopped.

Cause

Feed and fuel were reduced in an attempt to stabilise the kiln and ultimately reduce NOx levels. The kiln was then stopped.

Corrective Action

NOx daily average was not exceeded.

Week 28 & 29 exceeded spot sample ELV of 30 (1.2 times ELV) as notified to the agency on the 09/08/12.

Date

Parameter

Emission point ref.

Cause

Corrective Action When the gearbox was replaced, the original equipment supplier was consulted and operational changes were made to the plant in an attempt to speed up the adjustment time of the new seed sludge. The SWWTP has now resumed normal operation and the BOD results for both SW-3 and SW-4 are in compliance.

11th and 18th July 2012

Breach of weekly SW-3 BOD ELV

SW-3

The incident occurred after an overhaul of the SWWTP following the mechanical failure of the aeration wheel gearbox. Repairs were made however the plant required re-seeding. It took a number of days for the seeded sludge to adjust to the plant, causing the elevated BOD results.

BOD [mg/L]

Suspended Solids[mg/L]

Result within 1.2 times ELV. As this is a spot sample, the limit value is 1.2 times the emission limit value of 25mg/L, in accordance with condition 4.3.3 of licence P0030-04

2.4 Condition 6.16 (ii) Noise Management Plan

>2.4.1 To show compliance with noise aspects of IPPC Licence Reg. No. P0030-03 and subsequently IPPC Licence Reg. No.

Reg. No. P0030-04, a Noise Management Plan was developed by ARUP Consulting Engineers in October 2009 and

reviewed internally in 2010, 2011 and 2012.

"The Noise Management Plan has been prepared to outline how noise generated during the

operation of the facility is being managed. The objective of the plan is to ensure that procedures

are put in place for the management of noise generated on-site and to prevent impacts on

local residents."

See section 5 of AER for full Noise Management Plan and Review

Schedule B.4 Monitoring of Noise Off - Site

>2.4.2 Annual Report on Noise Levels Measured Off Site -

To show compliance with noise aspects of IPPC Licence Reg. No. P0030-04 a noise surveywas carried out by NVM Ltd over the period 22/08/2012 to 22/10/2012 at the three Noise Sensitive Locations agreed with the agency, namely Collier's Residence, Curran's Residence and Sinnot's Residence.

Dust deposits are monitored both on and off site by means of dust deposit gauges which were installed in

accordance with the requirements of the EPA. Due to the nature and location of the off-site monitoring locations,

the data arising from this monitoring can reflect dust deposition (e.g. arising from road traffic or agricultural activities)

which does not necessarily arise from the activities of Irish Cement Platin Works.

All sample ports will be sanded down so to remove as much rust from the sampling port as possible before future tests are carried out.

Emission point ref. A2-08

A full investigation was completed by both the stack testing company and ICL upon receipt of analysis of the sample result. It has been concluded by both parties that the test run in question was invalid due to rust contamination. Visual investigations have concluded that the rust in the sample most likely arose from the stack sampling port.

Cause

Incidents Relating to Aspect: Water Emissions

11th and 18th July 2012

Breach of weekly SW-3 BOD ELV

When the gearbox was replaced, the original equipment supplier was consulted and operational changes were made to the plant in an attempt to speed up the adjustment time of the new seed sludge. The SWWTP has now resumed normal operation and the BOD results for both SW-3 and SW-4 are in compliance.

Corrective Action

ParameterCampaign periodic monitoring: Sum of Sb; As; Pb; Cr; Co; Cu; Mn; Ni and V

Emission point ref. SW-3

Cause

The incident occurred after an overhaul of the SWWTP following the mechanical failure of the aeration wheel gearbox. Repairs were made however the plant required re-seeding. It took a number of days for the seeded sludge to adjust to the plant, causing the elevated BOD results.

Emission point ref. A2-08

Cause

Corrective Action

Spare parts were installed immediately however the electrical malfunction remained. Remedial maintenance was carried out as soon as was practicable which brought the analyser back into normal operation.

On Friday evening 15th of June 2012, an electrical malfunction occurred within the Kiln 3 Stack (A2-08) SICK RM230 dust monitor. The dust monitor required specialist maintenance to return it to normal functionality. Independent isokinetic monitoring was carried out while repairs were being made to analyser.

Cause

Corrective ActionFeed and fuel were reduced in an attempt to stabilise the kiln and ultimately reduce NOx levels. The kiln was then stopped.

A2-02Emission point ref.

Kiln 2 was started at 23.30 on the 3rd Dec. At 01.00 the kiln was operating steadily. Feed to the kiln was then lost for 3 – 4 minutes. This resulted in process instability which led to a rise in NOx levels. Attempts were made to stabilise the kiln and as a result there was a period

where the half hourly NOx limit of 1000 mg/m3 was exceeded. The kiln was then stopped.

Continue to target increases in waste segregation and recycling and so reduce waste

disposal to landfill. Environmental Engineer. Initiatives to maximise the volume of overburden consumed in the process and hence reduce the volume of extractive waste from the process is ongoing. Initiatives to maximise the recycling of packaging materials, including wood pallets is ongoing.

Continue to reduce the clinker content in cement to reduce the CO2 emissions per tonne

of cement. Production Manager. Platin further increased the substitution of limestone in cement to reduce the CO2 emissions per tonne of cement.

Complete upgrade of old plant control system to a new plant control system, integrating

all parts of the plant to a single modern control system. Works Engineer. Platin Upgrade Work continued in 2012 converting the control system from Cemat Version 4.12 to a PCS7 system from Siemens, the conversion was completed for a number of plant items in 2012. This upgrade work is ongoing.



2. Cleaner production / technology – Abatement / Treatment Systems improvements resulting in improved emission management:

Continue the ongoing optimisation work and continuous improvements on emission

abatement systems, including assessments of abatement system operation during the co-incineration of SRF. Environmental Engineer. There is ongoing optimisation with the K3 SNCR system due to the new lower NOx limit with Licence P0030-04.

Implement the plan for the monitoring of minor bag filters.

Environmental Engineer. Minor Bag Filters were tested as per plan, all filters tested were found to be in compliance with their licence limits. Ongoing further implementation of the plan.

1. INTRODUCTION 1.1 Background

Irish Cement Ltd. operates a large limestone quarry and cement manufacturing facility at the

Platin Works near Drogheda, County Louth. The trade effluent from this site is discharged into

the River Nanny near Duleek, Co. Meath. This discharge is licensed by the Environmental

Protection Agency (EPA) under Integrated Pollution Control (IPC) License Register Number

P0030-04. This license has a number of conditions in relation to the monitoring of the

receiving water. The current assessment addresses the receiving water monitoring issues in

relation to the following conditions as follows:

Condition 6.14.1 The licensee shall annually evaluate the impact, if any, of the

discharge to the River Nanny. The evaluation shall be based on the ambient sampling

required under Schedule C.6 Ambient monitoring [receiving water monitoring]. In

particular the evaluation shall consider the impact of fine particulate matter in the

discharge

Condition 6.14.2 The licensee shall, if necessary, based on the results of the

evaluation incorporate additional mitigation measures for the treatment of surface

water prior to discharge.

Condition 6.14.3 The acute toxicity of the undiluted final effluent to at least four

aquatic species from different trophic levels shall be determined by standardized and

internationally accepted procedures and be carried out by a competent laboratory.

The name of the laboratory and the scope of testing to be undertaken shall be subject

to the agreement of the agency. The testing shall be carried out within three months of

the date of grant of this licence. Copies of the complete reports shall be submitted to

the agency within 6 weeks of completion of the testing.

Condition 6.14.4 Having identified the most sensitive species outlined in Condition

6.14.3, subsequent compliance toxicity monitoring on the two most sensitive species

shall be carried out annually by the laboratory identified in Condition 6.14.3, or an

alternative as may be agreed. Copies of the complete reports shall be submitted to

the agency within 6 weeks of completion of the testing.

Condition 6.14.5 A representative sample of effluent shall be screened annually for

the presence of organic compounds and heavy metals. The specification of such shall

be amended upon the instruction of the Agency. Copies of the complete reports shall

be submitted to the Agency as part of the AER.

This study provides all the required information and meets these conditions. The current study

was undertaken by Ecofact Environmental Consultants Ltd. and follows a similar assessment

completed in 2010 and 2011 as part of the requirements for the same discharge license.

Ecofact Environmental Consultants Ltd. also undertook similar monitoring as part of the

previous discharge license during 2008 and 2009 (Ecofact, 2008, 2009).

1.2 The River Nanny The River Nanny (OS Catchment No: 160; EPA code: 08N01) is located in County Meath in

the Eastern River Basin District (Hydrometric Area 8). The River Nanny rises near Kentstown

and flows east through Duleek and Julianstown to enter the sea at Laytown, roughly 6 km

south of Drogheda. Overall it has a total length of 28 km and a catchment area of 239 km2

(McGinnity et al, 2003). Upstream of the discharge point, the catchment area of the River

nanny is approximately 200km2. At this location, the river has a 50%ile and 95%ile flow of

1.91m3/s and 0.323m

3/s respectively (EPA Hydrometric data system).

The River Nanny has a long history of pollution; mainly from agricultural sources (McGarrigle

et al, 2004). In Appendix 2, a summary of water quality in the River Nanny along with overall

water quality in Hydrometric Area 8 during the most recently published EPA survey is

presented.

The entire River Nanny was in an unsatisfactory ecological condition when most recently

monitored by the EPA in August 2010 (source EPA website). The stations at Folistown (0400)

and the east Bridge at Kentstown (0110) were both rated ‘Moderately Polluted (Q3)’,

equivalent to Water Framework Directive (WFD) ‘poor status’. The nearest EPA biological

monitoring station upstream of the Irish Cement discharge is at the bridge upstream of Nanny

Bridge. This part of the river was rated ‘Slightly polluted (Q3-4)’ corresponding to WFD

‘moderate status’. Downstream of the study area, the River Nanny was rated ‘‘Moderately

Polluted (Q3)’ at the Bridge NE of Bellewstown House (station 0500) and at the Bridge at

Julianstown (station 0700).

The River Nanny is in the Eastern River Basin District and is within the Nanny Water

Management Unit (WMU) where the land use is predominantly agricultural (ERBD, 2009). A

Water Management Unit (WMU) is a geographic area primarily defined by similar hydrology

and topography.

2. METHODS

2.1 Site location

The locations of the six study sites (Site N1 to N6) are given in Table 1 and Figure 1. The

location of the discharge from the Irish Cement plant is also indicated in Figure 1. Site

photographs are provided in Plates 1 to 6. The sites surveyed are at the same locations as in

previous assessments (i.e. Ecofact, 2008 - Ecofact, 2011). Freshwater toxicity tests (eco-

toxicology testing) were carried out on a sample of the discharged effluent. The sampling

location was within the Irish Cement premises at NOS Grid Reference O06602 71234 i.e.

approximately 15 meters south of the southern entrance to the plant and 5 meters west of the

R152 Road (see Plate 7).

2.1 Biological Assessments 2.1.1 Macroinvertebrate sampling

Semi-quantitative sampling of benthic macroinvertebrates was undertaken at the six sites

listed using kick or sweep sampling (Toner et al, 2005). Sampling was undertaken on the 24th

and 25th of July 2012. A total of three sites were located within a 0.5 km section of river

extending upstream of the Irish Cement discharge point (reference sites), and three sites were

located over a similar distance downstream (receptor sites). Representative riffle, glide and

pool habitats (EA, 2003) were sampled at both reference and receptor locations. Site 1 was

located downstream of an old mill weir while site N2 was located upstream of this

impoundment. The presence of this weir on the section can be expected to influence local

sedimentation rates.

The biological sampling procedure followed at each site involved the use of a ‘D’ shaped hand

net (mesh size 0.5 mm; 350 mm diameter) which was submerged on the river bed with its

mouth directed upstream. The substrate upstream of the net was then kicked for one minute

in order to dislodge invertebrates, which were subsequently caught in the net. This procedure

was undertaken at three points along/across the watercourse. Stone washings and vegetation

sweeps were also undertaken over a further 1 minute period to ensure a representative

sample of the fauna present at each site was collected.

All three samples of invertebrates from each substation were combined and live sorted on the

river bank for 20 minutes with the assistance of a headband magnifier. Specimens were fixed

in a 10% formalin solution. Identification was undertaken in the laboratory using high-power

and low-power binocular microscopes. All collected samples have been archived and will be

retained for 1 year.


___________________________________________________________________________ www.ecofact.ie 6

2.1.2 Biotic Indices 2.1.2.1 The Quality Rating (Q) System The Quality Rating (Q) System (Toner et al, 2005) is the standard biotic index which is used

by the EPA. This method categorises invertebrates into one of five groups, depending on their

sensitivity to pollution. Further details on the Q-rating system and its relationship to the

European Communities Environmental Objectives (Surface Waters) Regulations 2009 (S.I.

272 of 2009) are provided in Appendix 1.

2.1.2.2 BMWP (Biological Monitoring Working Party) Score

In the revised BMWP scheme (Walley and Hawkes, 1997) biotic index of water quality, each

family recorded in the sample is assigned a habitat specific score. This score depends on the

pollution sensitivity of the invertebrate family together with the characteristics of the site where

the invertebrates were found. A site is classed as one of the following depending on substrate

type: riffle (>= 70% boulders and pebbles), pool (>= 70% sand and silt) or riffle/pool (the

remainder). The BMWP score is the sum of the individual scores of the families recorded at

each site - a family scores if present. A higher BMWP score is considered to reflect a better

water quality and a score over 100 is indicative of very good water quality.

2.1.2.3 Trent Biotic Index The Trent Biotic Index (Woodiwiss, 1960) is based on the number of defined taxa of benthic

invertebrates in relation to the presence of six key organisms found in the fauna of the sample

site. Depending on the number of taxonomic groups present and the key organisms found in

the fauna, the TBI index ranges from ten for clean water, to zero for polluted water.

2.1.2.4 Chandler Biotic Score The Chandler Biotic Score (Chandler, 1970) also assigns values to taxonomic groups ranked

in terms of pollution sensitivity but, in addition, provides scores for each species which is

present in the taxonomic groups. This is a more powerful, albeit more taxonomically

demanding, system than the previous biotic indices. Each group is given a score according to

its abundance. The total score represents the index and the higher the score the cleaner the

water.

2.1.3 Functional Group Analyses Functional Group analysis is a classification technique for stream macroinvertebrates which

involves the functional analysis of invertebrate feeding, based on morpho-behavioural

mechanisms of food acquisition. A number of functional feeding groups of invertebrates occur

in streams. These are Shredders, Collectors (or filterers), Scrapers (or grazers), and

Predators. Shredders chew, mine, bore and gouge large particles such as leaves, sterns and

branches which may be dead or alive. Filterers filter particulate matter, alive or dead, from the

water. Collectors again feed on small particulate matter but gather the fine detritus off the

sediment or other surfaces rather than from the open water. Grazers graze and scrape the

periphyton off other surfaces. Predators are subdivided into engulfers, which eat the whole

prey item swallowing it whole or by chewing, and piercers, which pierce the prey and suck

fluids out. Food sources vary along the length of a river. Narrow upland streams, for example,

rely heavily on allochthonous leaf debris (known as CPOM or Coarse Particulate Organic

Matter) which can be used by shredders. In downstream areas, the fine debris of demolished


___________________________________________________________________________ www.ecofact.ie 7

leaves (known as FPOM or Fine particulate Organic Matter) will support collectors. Changes

in functional groups reflect changes in food sources, nutrient processing and energy flow in

the river system. Human influences on a river can dramatically alter food sources and in turn

affect the trophic groups. This method of analyses was therefore used as it provides a high

resolution insight into the ecology of a river and has the ability to detect more subtle changes

in community structure than would be apparent from biotic indices. Some of the mayfly larvae

recorded exhibit dual feeding strategies (scrapers and collector gatherers). In the functional

group analysis, where this occurred 50% of mayfly larvae were categorized as scrapers and

50% as collector gatherers.

2.1 Sediment and Water Sampling A sediment sample was obtained for analyses at each of the six sites using a hand held grab.

Three sub-samples were taken and combined into a composite sample for each site. Each

sub-sample was taken from undisturbed relatively homogeneous sediment deposits at the

site. Each sample was placed into a mixing bowl and objects such as sticks and leaves etc.

were removed as necessary. The sample was then stirred thoroughly with a mixing spoon to

homogenize. The sample was then placed into a glass sample jar.

Substrate samples were also taken from the riverbed at each site using a core sampler.

Depositing parts of the river were selected for this sampling with the aim of collecting

undisturbed samples of saturated sands, silts, and sediments. The profile of these samples

were examined in the field on a tray for the presence of accumulations of silt /clay near the

surface.

A water sample of the effluent was taken on the 25th July 2012. The water sample was

analysed for Total Petroleum Hydrocarbons, Diesel Range Organics, Heavy Metals and

Petroleum Range Organics. BOD (Biochemical Oxygen Demand) and Total Hardness were

analysed in samples taken from Sites N1 and N6. Samples were labelled and placed in a

cooler box and were promptly delivered to the laboratory (BHP Laboratories, Limerick). During

sampling appropriate measures to prevent contamination from other sources was undertaken

and all sampling equipment had been thoroughly cleaned.

2.2 Eco-toxicology testing Condition 6.14.4 of the IPPC license requires toxicological testing to be carried out on the two

most sensitive species tested in 2010. The species chosen for toxicity resting was a

freshwater crustacean Daphnia magna which was subject to an immobilization test and a

bioluminescent bacteria Vibrio fischeri in a Microtox - light inhibition test.

Toxic pollutants can be described in terms of acute and chronic toxicity. Acute toxicity is when

a large dose of pollutant is released in a short period of time whereas chronic toxicity is a low

dose of pollutant released over a long period of time, the former having more of a lethal effect

on the biota of the receiving water. Chronic toxicity can be lethal or sub-lethal and can result in

the mal-functioning of organisms by impairing biochemical, physiological, behavioral or life-

cycle functions. When toxic pollutants enter the aquatic environment they may be altered by

influences such as temperature, the quality of the water, pH and hardness. It is well known

that temperature influences the metabolic activity and behavior of organisms however it can

also alter the physical and chemical state of pollutants. For some toxicants, increasing

temperature results in increasing toxicity of the pollutant.


___________________________________________________________________________ www.ecofact.ie 8

Toxic contaminants are rarely individual chemicals, effluents or metals; more often than not

they are mixture of poisons. When two or more pollutants are present in an effluent they may

exert a combined effect on an organism which is said to be additive, the contaminants may

also interfere with one another, an antagonistic effect or the overall effect of the pollutant on

an organism maybe greater than when acting alone, a synergism effect (Mason, 2002).

In order to minimize the effects of pollutants on the environment toxicity tests have been

developed to assess the toxicity of an effluent and to predict, in conjunction with other

information e.g. available dilution, chemical characterisation, the impact it will have on the

receiving waterbody. The receiving waterbody dictates the selection of the test organisms.

The receiving waterbody is freshwater.

Toxicity testing is essentially for environmental protection of an area, to control the wastes

from animal residues and humans, to monitor industrial and manufacturing processes in order

to issue discharge licences, for legal and ethical issues i.e. to protect biota in aquatic

ecosystems. Toxic units are used in Irish discharge licenses for compliance monitoring and

the general limits for these toxic units are outlined below in Table 2 below. The higher the

Toxic Unit value, the greater the toxicity. A single toxic unit would signify a marginal or

negligible level of toxicity while 3TU might suggest some potential for effects (Cronin, 2006).

Table 2 Interpretation of toxic units.

Toxic Units Description

<3 Non toxic

3-10 Slightly toxic

11-50 Toxic

50-100 Very toxic

>100 Extremely toxic

The objectives of toxicity tests are to:

1. Assess the toxicity and lethality of compounds i.e. to what extent are the compounds

hazardous to the environment, to humans, to animals etc.

2. To test the effects of environmental factors on waste toxicity i.e. temperature, pH,

salinity, water hardness

3. To investigate trophic mobility i.e. how do compounds move up through the

ecosystem

4. To test the toxicity of a waste to a test species i.e. at each trophic level a test species

is investigated e.g. a primary producer, primary consumer and secondary consumer.

A sample of the discharge from the Irish Cement plant was taken on the 25th July 2012. The

sample consisted of 1litre and was taken by accessing the discharge via a manhole adjacent

to the R152 road. The sample of the discharge was placed in a cooler box and immediately

brought to the SATL. Toxicology tests were carried out on the sample by Shannon Aquatic

Toxicity Laboratories (SATL). This is a specialised facility for culturing and testing aquatic

organism which has been accredited for Daphnia and Microtox testing. The tests carried out

were as follows:

48 h EC50 to Daphnia magna

15,30 min EC50 to Vibrio fischeri

The methodology used for each of the above tests followed the “Organization for Economic

Co-operation and Development (OECD) guidelines for testing of chemicals”. Data from each


___________________________________________________________________________ www.ecofact.ie 9

test was used to screen for toxicity i.e. to determine if the effluent was toxic. Each test is

discussed separately below. In each test a concentration series is set up where the test

organism is placed in 100%, 56%, 32%, 18%, and 10% neat effluent. A control is set up; for

Daphnia potassium dichromate is a reference chemical and for the bacteria Vibrio fischeri, the

metal zinc sulphate is commonly used. Exposure times are pre-determined depending on the

species being tested. Further details of each test are provided below.

2.2.1 48 h EC50 to Daphnia magna Effective Concentration (EC) is the term used when an effective other than death is used such

as respiratory stress, behaviour or developmental abnormalities. This method followed the

‘OECD guideline for the testing of chemicals’ within the section ‘Daphnia magna acute

immobilisation test’. This freshwater cladoceran is ubiquitous, is sensitive to pollutants, has a

high reproductive rate (Daphnia reproduce asexually every 10-12 days), is easily cultured, has

a role in many food webs and its ecology has been well studied (Mason, 2002). Therefore it is

widely used in toxicity testing. Daphnia magna neonates (less than 24hours old) are exposed

to the varying concentrations of the effluent sample usually with five replicates of 10

individuals for each concentration. The concentrations follow a geometric series and the EC50

values are calculated using appropriate software e.g. MINITAB. From this the estimated

percentage of immobilised Daphnia after 48hours is calculated.

2.2.1 15, 30 min EC50 to Vibrio fischeri This test involves using the marine bacteria Vibrio fischeri. This is a photoluminescent

bacteria. This toxicity test is based on a decrease in light output. If properly grown these

bacteria produce light (a by-product of cellular respiration). An inhibition of cellular activity

(toxicity) results in decreased rates of respiration and a decrease in the rate of luminescence.

This method involves using freeze-dried bacteria which have a shelf life of up 18 months and

a temperature controlled (15 to 27oC) photometer is used to measure light output. The test

measures luminescence inhibition after 15 and 30 minutes of exposure and is commonly used

for wastewater treatment testing, surface water monitoring and sediment and soil

contamination testing.

2.3 Habitat Survey Physical habitat assessments were undertaken at the six biological sampling sites. Habitat

has a key influence on the macroinvertebrate communities, which occur in rivers and streams.

The physical habitats of study sites were assessed in relation to macroinvertebrates using a

method given by Barbour and Stribling (1991). This method assesses habitat parameters and

rates each parameter as optimal, sub-optimal, marginal or poor (scores 5, 10, 15 and 20

respectively). The scores for each parameter are then added up to give an overall habitat

score.

2.4 Other WQ parameters During the current survey Conductivity (µs cm

-1), water temperature (

oC), and Dissolved

Oxygen (mgl-1

and % saturation) were measured using on-site using portable meters. These

parameters, along with salinity and pH were also measured in the water sample provided to

Enterprise Ireland for eco-toxicology testing.

3 RESULTS AND DISCUSSION 3.1 Physical Habitat The physical habitat characteristics of the six sites assessed during the July 2012 survey are

presented in Table 3. The physical habitat assessment of the six sites with respect to their

suitability for macroinvertebrate production is presented in Table 4. All sites were rated as being

sub-optimal for macro-invertebrate production with generally marginal pool quality, habitat

complexity and canopy cover. Siltation in the surveyed stretch of river continues to be a problem

despite the unusually wet summer brought about by the high rainfall levels. In the past, the EPA

has indicated that land disturbance (such as ploughing) could possibly be a cause of siltation in

the river. Indeed, a large proportion of lands in the study area are used for crops such as

potatoes and grains which require ground preparation and exposing bare soil, with potential for

suspended solids runoff.

3.2 Temperature, Conductivity, Dissolved Oxygen and other WQ

parameters

3.2.1 Results of the on-site assessments On-site water quality assessments were carried out on the 24

th and 25

th of July 2012 at the six

sites sampled on the River Nanny (see Table 5). It is noted that Sites N1 to N5 were sampled on

the 24th

at a time when water levels were considered slightly higher than normal. Site N6 was

sampled on the 25th of July and following overnight rainfall, the river was in flood at this time.

However, the sampling could still be completed and water levels did not significantly affect the

sampling. It is noted that 2012 was a very wet year and it was impossible to time this year's

survey to a period of low rainfall.

Dissolved Oxygen (D.O.) concentrations ranged from 78% saturation (Site N6 at 11.30) to 109%

saturation (Site N2 at 15.55). With regard to D.O. concentrations on the 24th July, there was little

variation between Sites N1-N5. Downstream of the discharge, D.O. was 107.6% at Site N1 (time:

14.05) rising to 109% at N2 (time: 15.55) and dropping back to 105% at N3 (time: 16.58).

Upstream of the discharge, D.O. was 108.4% at N4 (time: 17.57) and 102.4% at N5 (time: 18.54).

Diurnal fluctuations in D.O. can be expected to occur naturally in rivers and the D.O. range is in

indication of aerobic activity and Biochemical Oxygen Demand (B.O.D.). In the EPA Q-rating

scheme, a D.O. within the range 80% - 120% is indicative of ‘Good status’ conditions. There was

little variation in the D.O. levels between Sites N1 and N5 over the period 14.05 to 18.54,

indicating stable oxygenation conditions and good water quality on the 24th July. The Dissolved

Oxygen (D.O.) saturation of 78% at Site N6 on the 25th was indicative of 'Moderately polluted'

conditions however. The decrease to 78% saturation at Site N6 was thought to be brought about

by lowering of D.O. concentrations overnight (absence of photosynthesis during darkness)

together with the turbid conditions resulting from the flood (low light penetration). Furthermore,

B.O.D. at Site N6 (and at other sites) probably increased during the flood conditions due to runoff

from lands in the catchment.

Conductivity was in the range 688 µS/cm - 708 µS/cm on the 24th July. On this day Conductivity

was lower at Sites N1-N3 downstream of the discharge point (mean value = 692 µS/cm), the

mean value of this parameter being 705 µS/cm at Sites N4 and N5. Conductivity was 565 µS/cm

at Site N6 which was sampled on the 25th July in high water conditions, significantly lower than

other sites. This result was deemed to be strongly influenced by runoff.

On-site water quality measurements of the discharge immediately upstream of the River Nanny

were taken on the 25th July. The conductivity of the discharge on this day was 682 µS/cm.

Dissolved Oxygen (D.O.) in the discharge at time 12.20 was 102% (10.17 p.p.m.) at a

temperature of 13.20C.

Based on the on-site chemical results for Dissolved Oxygen and Conductivity, there was no

evidence to suggest that the River Nanny was being negatively affected by the Irish Cement

discharge.

3.2.2 Laboratory results

Chemical water quality results for the discharge were obtained from the sample taken on the 25

th

July for testing. The Dissolved Oxygen (D.O.) saturation was 100% at 18.50C. Salinity was <1ppt

at 200C. pH was 7.4 at 18.4

0C. The discharge was also analysed for Total Petroleum

Hydrocarbons, Diesel Range Organics, Mineral Oils, Total Volatile Organic Compounds (TOC's)

and Heavy Metals. The full suite of results for particular species can be seen in Appendix 3.

All Total Petroleum Hydrocarbons (C6-C40, C6-C8, C8-C10, C10-C12, C21-C40) analysed were below the

level of detection at <0.001mg/l. Petroleum Range Organics and Diesel Range Organics were

also present in concentrations less than 0.001mg/l. Mineral Oil concentration was less than

0.01mg/l. In the Freshwater Fish Directive (79/923/EEC) and Salmonid Waters Regulations

(1988) there are no recommended or mandatory limit values for Hydrocarbons. However, it is

stated that Petroleum products must not be present (in water) in such quantities that they: - form

a visible film on the surface of the water or form coatings on the beds of water-courses and lakes

- impart a detectable 'hydrocarbon' taste to fish - produce harmful effects in fish. In this respect,

the discharge was compliant as no slick was seen nor did it impair the water surface of the River

Nanny following mixing.

Table A4.3 presents BOD (Biochemical Oxygen Demand) and Total Hardness results from Sites

N1 and N6 on the River Nanny. Water samples for these parameters were taken on the 25th July.

BOD downstream of the discharge was 1mg/l and 2mg/l upstream of the discharge. Total

hardness downstream (Site 1) and upstream (Site 6) of the discharge was 320mg/l and 300mg/l

respectively.

Results for Heavy Metals including Arsenic, Copper, Cadmium, Chromium, Lead, Nickel, Tin and

Selenium were all below the level of detection (L.O.D.) i.e. <1 µg/l, with Mercury below the 0.2

µg/l L.O.D. Zinc was the only Heavy Metal detected at a concentration greater than 1 µg/l, this

parameter was present in the trade effluent sample at a concentration of 12 µg/l. In the European

Communities Environmental Objectives (Surface Waters) Regulations 2009, the Maximum

Allowable Concentration (MAC) for Zinc in inland surface waters is dependent on water hardness.

The annual average MAC for Zinc is 8 μg/l for water hardness with annual average values less

than or equal to 10 mg/l CaCO3, 50 μg/l for water hardness greater than 10 mg/l CaCO3 and less

than or equal to 100 mg/l CaCO3 and 100 μg/l elsewhere. The annual average MAC for Zinc in

the River Nanny is therefore 100 μg/l considering Hardness in the River Nanny was in the range

300-320mg/l. Zinc in the trade effluent would be significantly diluted by the River Nanny following

mixing, and the concentration of Zinc in the River Nanny downstream of the discharge point

would be significantly less than 12 μg/l, and well below the annual average MAC of 100 μg/l.


___________________________________________________________________________ www.ecofact.ie 14

Based on laboratory results for BOD, hardness, Organic compounds and Heavy Metals, there

was no evidence to suggest that the River Nanny was being negatively affected by the Irish

Cement discharge. The overall results obtained are very similar to the previous monitoring

assessments.

3.3 Sediment PSD The results of the PSD (particle size distribution) analyses of fine sediments sampled at the six

survey sites are presented in Table 6.

The bulk of the fine sediments sampled in the current study comprised sand and gravels.

Samples at Sites N2-N5 contained no pebbles, N1 the only sample with this substrate type (only

1%). There was little difference in the PSD between riffled Sites N1 and N6. At Sites N1 and N6,

85% and 89% of particles were less than 6.3mm (lower threshold for gravel) respectively. At Sites

N1 and N6, 15% and 11% of particles were less than 0.15mm (lower threshold for sand), in that

order. The finest fraction of particles (corresponding to silt/clay) at Site N1 was 12% and 9% at

N6. The main component of the samples taken at the glide sites N2 and N5 was between

0.15mm and 5mm i.e. sand. The proportion of sand at Site N2 and N5 was 53% and 46% in that

order. There was a higher percentage of the finer sands at the reference site N5 than the receptor

site N2. The reference glide site (N5) had slightly more silt/clay particles (10%) than the receptor

glide site (8%). The pool sites N3 and N4 are the nearest receptor and reference sites to the point

of discharge respectively. The sample at N3 consisted of 11% gravel material (6.3mm-14mm).

Particles in this size range accounted for 22% of the sample at N4. The dominant matter in the

glide samples was sand. There was close correspondence of larger grained sands between Sites

N3 and N4. For example, 76% and 72% of particles were less than 5mm at Site N3 and N4

respectively, with 65% of grains at both sites less than 3.35mm. The proportion of smaller grain

sands at Site N4 increased relative to N3. For example, the smallest sized sand (0.063-0.15)

comprised 25% of material in the N4 sample and 17% in the N3 sample. The silt/clay proportion

at Sites N3 and N4 was 11% and 14% respectively.

Visual examination of core samples taken from depositing parts of the river at each site did not

detect any major differences in substrate composition across the study area. In particular, there

was no observable variation in the fine top layer of samples. Profiles of substrates from core

samples largely corresponded with the PSD results.

The current PSD and field results do not show any noteworthy difference in fine substrate

composition between samples taken upstream and downstream of the Irish Cement trade effluent

discharge point. In particular, the component of the substrate most likely to be influenced by the

discharge (i.e. the silt/clay fraction of samples) did not increase in samples taken downstream

of the discharge point. The results obtained are very similar to the previous monitoring

assessments.

3.4 Macroinvertebrate Diversity and Abundance Table 7 presents the results of the on-site macroinvertebrate survey at the six sites surveyed on

the River Nanny during July 2012. Macroinvertebrate diversity and abundance at each of the six

sampling sites is illustrated in Figure 2.

During the survey of the six sites, a total of 1,983 macroinvertebrates comprising 38 families were

identified. At the receptor sites a total of 1005 macroinvertebrates were collected while a total of

978 macroinvertebrates were collected at the references sites. Family richness for the receptor

sites combined was 36 in comparison with 32 at the references sites combined.

Macroinvertebrate family diversity at Site N1, the receptor riffled site was 24. Mayfly recorded at

this site were larval pollution tolerant Baetis rhodani (fair numbers) and Ephemerella ignita

(numerous) as well as pollution sensitive Ecdyonurus dispar (present). Pollution tolerant larvae of

blackfly was the most abundant organism at this location. The crustaceans Asellus aquaticus and

Gammarus deubeni were numerous and few respectively. Molluscs recorded at this site were

Bithynia tentaculata, Ancylus fluviatilis and Pisidium sp. Trichopterans (caddisflies) were

represented by two cased (Goera pilosa, Potamophylax sp.) and two un-cased families

(Polycentropus kingi, Rhyacophila dorsalis). The beetles Potamonectes depressus elegans,

Helephorus sp., Haliplus sp. and Elmis sp. as well as aquatic earthworms were also recorded

among the macroinvertebrate assemblage at this site.

The receptor glide site (N2) had a family richness of 28, the most families recorded at any site

during the current assessment. Ephemeropterans were a well represented group with four

species recorded; B. rhodani, E. ignita, E. dispar and Caenis sp. An equally assorted group were


___________________________________________________________________________ www.ecofact.ie 16

the Trichopterans, with larvae of the following Group B less sensitive/cased species

scarce/present: Sericostoma personatum; Potamophylax sp., Lepidostoma hirtum and Goera

pilosa. True fly larvae of Simulidae, Green chironomids and Chironomous sp. all tolerant of

pollution were generally common at this location. B. tentaculata, P. carinatus, Pisidium sp., Physa

sp. and A. fluviatilis were also found these molluscs by and large recorded in small numbers.

Other macroinvertebrates recorded at this site were Sialis sp. (alderfly larvae), Helophorus sp.

and the leeches Erpobdella octoculata and Glossiphonia complanata.

A total of 22 macroinvertebrates families were recorded at the receptor pool site (N3). The most

diverse order of macroinvertebrate at this location were Coelopterans with beetles in 5 families

recorded. P. depressus elegans was common, with other beetles (Helephorus sp., Haliplus sp.,

Gyrinus sp. and Elmis sp.) present or recorded in fair numbers. Fair numbers of pollution tolerant

G. deubeni and very tolerant A. aquaticus were recorded. Mayfly larvae of B. rhodani and Caenis

sp. were present and scarce in that order with fair numbers of E. ignita. Trichopteran larvae

recorded were limited to cased species, Potamophylax sp., Hydroptila sp. and L. hirtum all

present. P. depressus elegans of Coeloptera were common with Elmidae, Hydrophillidae and

Haliplidae being generally scarce in this group. The assemblage also comprised the molluscs B.

tentaculata and Pisidium sp. Other organisms recorded at this site were the bugs Notonectidae

(Greater water boatman) and Gerris sp.

A macroinvertebrate family richness of 23 was recorded in the reference pool site (N4). The most

abundant macroinvertebrate at this site was the snail B. tentaculata which was abundant. Other

molluscs recorded at this location were Physa sp. and A. fluviatilis (both present). The

Crustaceans G. deubeni and A. aquaticus were common and scare in that order. Mayfly larvae of

E. ignita were common while larval B. rhodani and Caenis sp. were present. The Trichopteran

community at this site was confined to cased caddisfly larvae of Potamophylax sp. and Hydroptila

sp Other macroinvertebrates recorded included the leeches Piscicola geometra and E.

octoculata, aquatic earthworms,) and Nematomorpha. The only damselfly larvae recorded during

the current study was at Site N4, with less sensitive Agrion splendens being scarce. Adults of this

species were also recorded on the wing and spent alongside the river.

A family richness of 27 was recorded at the reference glide (Site N5) where a total of 260

macroinvertebrates were recorded. Pollution tolerant G. deubeni and very tolerant A. aquaticus

were common. Fair numbers of bloodworm Chironomous sp., green chironomid and Simulidae of

Diptera were recorded with Dicranota sp. of this group being present. The Trichopterans were the

best represented group at this site. Caseless caddisfly larvae of Hydropsyche sp. and

Rhyacophila dorsalis were present with cased larvae of S. personatum, Potamophylax sp. and L.

hirtum generally scarce. Mayfly larvae of B. rhodani, E. dispar and Caenis sp. were

scarce/present with larval E. ignita being common. In addition, aquatic earthworms

(Lumbriculidae and Lumbricidae), leeches (P. geometra, E. octoculata) and molluscs (A.

fluviatilis, B. tentaculata, Pisidium sp.) were recorded at this site.

Macroinvertebrates in different 22 families were recorded at the reference riffle site (N6). Mayfly

larvae of E. ignita were numerous while fair numbers of B. rhodani were recorded. G. deubeni

and A. aquaticus were found in fair numbers and small numbers, in that order. Pollution tolerant

true fly larvae of the Simulidae and green chironomids were generally common, most tolerant

Chironomous sp. being scarce and Dicranota sp. being present. Trichopteran larvae were


___________________________________________________________________________ www.ecofact.ie 17

generally scarce, the following being recorded: Hydropsyche sp. R. dorsalis, S. personatum,

Potamophylax sp. and L. hirtum.

The macroinvertebrates recorded during the current survey are typically those associated with

polluted lowland Irish limestone rivers. Molluscs and crustaceans were the most abundant groups

recorded and far outweighed any other major macroinvertebrate groups.

Compared to 2011, there was a decrease in family richness at riffled Sites N1 and N6. All other

sites showed a reversal of this trend, with family richness at glide and receptor sites increasing

both upstream and downstream of the discharge point. There was however no evidence to

suggest that the macroinvertebrate communities of the River Nanny are being negatively affected

by the Irish Cement discharge.

3.4 Biological Water Quality The current survey was carried out during July 2012. The summer of 2012 was extremely wet

and water levels in most rivers in the country were above normal during the summer. The river

was examined at a time when water levels were above normal on the 24th July (Sites N1-N4) with

the river in flood when surveyed on the 25th July (Sites N5 and N6). Even with the higher than

normal water levels, excessive algal growth was evident on submerged aquatic vegetation. In

addition, underwater features visible at the time of the survey were seen to have a considerable

coat of deposited silt. These factors are usually associated with unsatisfactory biological water

quality.

The glide sites N2 and N5 had the greatest macroinvertebrate diversity. It is noted that higher

species richness values, linked to family richness are mostly associated with clean water

conditions. The receptor riffle site (N1) had a family richness of 24 compared to a family richness

of 22 at the corresponding reference riffle site (N6). The family richness at the receptor glide (N2)

and the reference glide (N5) was 28 and 27 respectively. Family richness at the pool sites N3

(receptor) and N4 (reference) was 22 and 23 respectively. The mean family richness at the

receptor and reference sites combined was 24.6 and 24 respectively. The results obtained for

family richness do not indicate that the discharge is influencing macroinvertebrate diversity in the

surveyed stretch of the river.

The biotic indices have been derived based on the macroinvertebrate communities found at each

site. The biological water quality evaluations for the six survey sites on the River Nanny are given

in Table 8.

Sites N1, N2 and N5 were rated 'Slightly Polluted (Q3-4)’ using the Q-rating system which is

equivalent to Water Framework Directive (WFD) ‘Moderate’ status. This rating is borderline

however and was brought about by the presence of pollution sensitive mayfly larva and relatively

stable oxygenation conditions. Sites N3, N4 and N6 were rated ‘Moderately Polluted (Q3)’,

equivalent to Water Framework Directive (WFD) ‘Moderate’ status.


___________________________________________________________________________ www.ecofact.ie 20

The only pollution sensitive species recorded was mayfly larvae of E. dispar, present at Sites N1,

N2 and N5. Group B cased caddisfly larvae were recorded at all survey locations. A family

diversity of 24 was recorded at the riffle receptor site in comparison to a family diversity of 22 at

the reference riffle site. Macroinvertebrate richness is related to water quality and since richness

was greater at the receptor site, it is considered that the discharge is not noticeably impacting on

macroinvertebrates. The riffled locations are probably the best sites on which to make an

assessment of biological water quality as these areas, owing to fast flowing water and better

habitat are most likely to support pollution sensitive indicators. Since the 2011 study, there has

been a general improvement in Q-ratings, the ecological status of Sites N1, N2 and N4 improving

from 'poor' status in 2011 to 'moderate' status in the current study.

The overall classification of macroinvertebrate species present at the receptor and reference sites

in terms of their pollution sensitivity is given in Figure 3 and Table 9. Group ‘C’ pollution tolerant

indicators comprise the bulk of the macroinvertebrate communities downstream (69% collectively

at receptor sites) and upstream (72% collectively at reference sites) of the discharge point. The

relative abundance of Group C indicators closely correspond to 2011 results. Comparing the

receptor and reference sites examined in 2012, there is also close correspondence between

pollution sensitivity Group ‘A’ (1%, 0.1%), Group ‘B’ (8%, 4%), Group ‘D’ (16%, 16%) and Group

‘E’ (6%, 8%) where percentages in parenthesis are for receptor and reference sites

correspondingly. Again, these results closely reflect the 2011 results.

Comparing Site N1 and Site N6, it can be seen that there is little difference in the relative

abundance of Group C indicators, N1 and N6 containing 90% and 84% pollution tolerant taxa

respectively. Group B (less sensitive) indicators accounted for only 2% of the assemblage at Site

N1 in contrast to 4% at Site N6. Very tolerant indicators (Group D) accounted for 6% of

macroinvertebrates at Site N1 and 9% at Site N6.

Similarly, there was little variation in the macroinvertebrate compositions at corresponding glide

sites in terms of pollution sensitivity groups. The amount of Group C indicators at Sites N2 and

N5 was 71% and 68% respectively. Group B indicators accounted for 3% of the assemblage at

N2 downstream of the discharge and 6% at N5 upstream. A significant proportion of the

macroinvertebrates at these locations consisted of most tolerant (Group E) indicators; 9% at Site

N2 and 6% at Site N5. The proportion of this indicator group decreased by approximately 50%

since 2011 however. There was little difference in the relative abundance of Group D indicators

at Sites N2 and N5, these very tolerant indicators accounting for 17% and 20% of the

macroinvertebrates assemblage at these locations, in that order.

The macroinvertebrate assemblages at Sites N3 and N4 comprised 78% and 91% Group C

indicators, 15% and 6% group D indicators, and 3% and 2% Group B indicators respectively, with

no pollution sensitive species recorded.

Figure 4 illustrates the Biological Monitoring Working Party (BMWP), Trent biotic index and

Chandler biotic index scores at the six survey sites. All BMWP scores were greater than 100

which is inductive of very good water quality. BMWP scores are proportional to family diversity. It

is noted however that macroinvertebrate assemblages in lowland limestone rivers area usually

highs sometimes even in polluted circumstances however. Indeed, other observations along he

surveyed stretch of the river did not correspond with unpolluted conditions however e.g.


___________________________________________________________________________ www.ecofact.ie 21

filamentous algal growth and siltation. The highest BMWP score was for Site N5 – the glide site

upstream of the discharge. This site scored 136.7 which is interpreted as very good or unpolluted.

The corresponding BMWP score downstream of the discharge (N5) was 123.5. BMWP scores at

the riffled sites N1 and N6 were 125.5 and 104.1 correspondingly. It is noted that the BMWP

scores at Sites N2 and N3 increased from values indicative of 'Moderately impacted' conditions in

2011. The Average Score Per Taxon (ASPT) which is a function of the BMWP score is deemed to

more accurately gauge water quality. The ASPT at Site N1 and N5 was 5.5, where an ASPT of

more than 5.5 is thought to reflect good water quality. Overall, analyzing the BMWP scores over

the study area does not point to a decrease in water quality at Sites N1, N2 and N3 with

reference to Sites N4, N5 and N6. The Trent biotic index scores for all survey sites was 9. Again,

as for the BMWP index, there was no determinable decline in water quality downstream of the

discharge point. There was very little difference in Chandler scores across the suite of sites

surveyed. Chandler average values varied from 42.6 at Site N4 to 47.7 at Site N5. The ideal

Chandler index value of 80 or more indicates an unpolluted, fast-running and well-aerated

watercourse. The Chandler scores during the current assessment fall well short of 80, due to the

absence of entire groups of pollution sensitive taxa such as stonefly and mayfly larvae. The

Chandler scores obtained in the current study were broadly similar to scores obtained in the 2011

study. Again, the Chandler scores do not indicate degradation in biological water quality

downstream of the discharge point.

There was no discernible difference in water quality between the sites upstream and downstream

of the Irish Cement discharge. Overall, the results confirm that biological water quality in the River

Nanny is the same upstream and downstream of the Irish Cement discharge. The general trend

was that the reference glide (N5) and receptor glide (N2) scored higher than other sites due to

greater family diversity.

Compared to 2011, there has been an overall improvement in biological water quality in the

surveyed stretch of river i.e. both upstream and downstream of the discharge location, water

quality in the river returning to that recorded in 2010. The unusually consistently higher than

normal water levels may have lead to this overall improvement in biological water quality since

last year. Based on the relative abundance of macroinvertebrate and biotic indices, it is

considered that the River Nanny is under ecological pressure; the only pollution sensitive

indicator (E. dispar) being present, and low relative abundance of Group B indicators. As

observed from year to year in previous surveys, the macroinvertebrate community in the

surveyed stretch of river is variable, indicating ecological instability brought about apparently by

pressures in the catchment.

3.5 Functional Groups The collective compositions of macroinvertebrate Functional Feeding Groups (FFG) at the

receptor sites and reference sites is presented in Figure 5. The dominant FFG at the receptor

sites was filtering collectors, macroinvertebrates that specialise in filtering. Filtering collectors

accounted for 31% of the assemblage at Sites N1, N2 and N3 combined. The proportion of

filtering collectors at the reference sites (N3, N4 and N5) was 24%. Shredders comprised 28%

and 37% of the macroinvertebrate assemblage at reference and receptor sites, in that order.

There was little difference between the abundance of predators with 14% predators at the

receptor and 12% predators at the reference sites. Gathering collectors represented 22% and

25% of macroinvertebrates recorded at receptor and reference sites in that order. Similarly, there

was close correspondence between the relative abundance of scrapers; 5% and 4% at the

receptor and reference sites respectively.

In comparison to FFG results for 2011, the most significant change has been the decrease in the

relative abundance of predators. The fraction of this FFG decreased from 21% to 14% at receptor

sites and from 16% to 12% at reference sites between 2011 and 2012. This trend follows that

seen last year where predator abundance also declined between 2010 and 2011. Another

noticeable decrease was observed in scrapers. This FFG formed 13% of macroinvertebrates

recorded at reference sites in 2011 in contrast to only 5% in the current study. The drop in relative

abundance of scrapers at reference sites was smaller, being 6% in 2011 and 4% in 2012.

Conversely, the relative abundance of gathering collectors recorded in the current study has


___________________________________________________________________________ www.ecofact.ie 23

increased since 2011 with the relative quantity of filtering collectors stable since 2011. The

decrease in scrapers and increase in gathering collectors could be attributed to the unusually wet

summer conditions in advance of the current survey work. Turbid water or water carrying a heavy

suspended solids load reduces light penetration and hence primary instream production upon

which scrapers depend. Thereby, a decrease in primary production such as reduced diatom

abundance would be expected to decrease the numbers of scrapers. Increased fine particulate

organic matter washed into the river during rainfall events would support collectors and the

relative abundance of this group would be expected to increase as observed in the current study.

More detail on the macroinvertebrate functional groups recorded at each site is provided in Table

10. The dominant FFG for each site along with the P/R ratio for each site is provided in Table 11.

The most frequently occurring shredders were Gammarus deubeni, Asellus aquaticus and

Bithynia tentaculata with cased larvae of caddisfly also present. G. deubeni was the most

abundant macroinvertebrate recorded at the riffled sites N1 and N6 while B. tentaculata and A.

aquaticus were more abundant in the slower flowing parts of the river (N2-N5). The relative

abundance of shredders was broadly comparable at corresponding receptor and reference sites.

At the riffled sites for example, there was 23% shredders at N1 and 26% shredders at N6. At the

glide sites, shredders comprised 33% and 38% of the assemblage at the receptor and reference

sites in that order.

Comparing the percentages of predators at the receptor sites and corresponding reference sites,

there was little difference: 6% at N1 and 7% at N6; 16% at N2 and 13% at N5. The dominant

predators were the beetles Potamonectes depressus elegans and Haliplus sp. with the leeches

Glossiphonia complanata, Erpobdella octoculata and Piscicola geometra also recorded.

The P/R ratio at all sites was considered very low as in previous surveys. This ratio, which is a

measure of gross primary production to community respiration is reduced by increasing numbers

of shredders and collectors. The most common scrapers recorded were Ancylus fluviatilis and

mayfly larvae of Baetis rhodani.

The P/R ratios at all sites are well below the threshold value of 0.75, above which an aquatic

ecosystem is deemed autotrophic. The results of the current survey are indicative of a highly

heterotrophic aquatic system (food supply originates from outside the aquatic system). The

relative abundances of scrapers (which increase P/R ratio) was greatest at Sites N1 (P/R=0.08)

and N6 (P/R=0.07). The P/R ratio at glide sites (N2 and N5) was equal at 0.05. Similarly, the P/R

ratios at the pool sites were the same at 0.02. The drop in P/R from riffle to glide to pool

correlates to depth to riverbed where most macroinvertebrates are found, the P/R decreasing with

increasing depth (most likely due to photosynthetic reasons outlined above).

All P/R ratios with the exception of Site N6 have dropped since 2011. Since 2011, the P/R ratio at

Sites N1 and N4 have undergone the most marked change. The P/R at the riffled receptor site

(N6) has decreased from 0.24 in 2011 to 0.08 and the reference pool site (N4) decreased from

0.23 in 2011 to 0.02 in the current study. The poor representation of scrapers throughout the

surveyed stretch of river is consistent year after year. The changes in relative abundance of this

FFG in successive surveys are slight and in the current situation, significant changes in P/R will

not occur considering the scarcity of this FFG.


___________________________________________________________________________ www.ecofact.ie 24

With respect to the 2011 survey, the only site where the dominant FFG has changes is at Site N3,

where shredders were dominant in 2011 and have been replaced by predators. Since 2011, sites

are collectively more heterotrophic than last year. In the current survey, there was no difference

between reference and receptor sites with regard to P/R ratios. This result does not indicate a

change in primary production taking place within the River Nanny downstream of the Irish

Cement discharge.

Table 12 presents a juvenile salmonid (salmon and trout) food index which assesses the

likelihood of a predictable invertebrate food supply being available for juvenile salmonids. The

results show that there was a predictable supply of food available at all sites with the exception of

Site N4. This result was brought about by the generally high proportion of gathering collectors

(mainly E. ignita, Simulidae and green chironomids). Since 2011, there has been a general

increase in the relative abundance of behavioural drifters (filtering and gathering collectors)

throughout the study area, with the effect of raising the juvenile salmonid food index and the

increasing the ability of the river to support young salmonids with respect to macroinvertebrates.

Overall, the poor supporting habitats, degraded water quality and limited food supply for

salmonids along the study stretch of river have significant consequences for the fishery status of

the River Nanny.

Flounder, brown trout, stone loach and minnow were recorded during the current field work

downstream of the discharge point with the three latter species recorded upstream of same.

European eel Anguilla anguilla was not recorded in the previous or the current study. European

eel has been listed as ‘Critically endangered’ and is now ‘Red Listed’ according to ‘Red List No. 5:

Amphibians, Reptiles & Freshwater Fish’ (King et al., 2011).

3.6 Toxicology The results of the toxicology tests as carried out by SATL are outlined in Tables 13 and 14 below.

No Daphnia magna were immobilised after 48 hours exposure to 100% vol./vol of the discharge

from the Irish Cement plant. This result signifies that the discharge was non-toxic to this indicator

i.e. a toxic unit value of <1. The effluent is therefore considered non-toxic with respect to this

trophic level.

The 30 minute EC50 to Vibrio fischeri found that no light inhibition occurred at 45% vol./vol. In

relation to this organism, the Toxic Unit value was <2.2 which again indicates that the effluent was

non-toxic to this test organism.

The toxicity testing showed that the effluent from the Irish Cement plant was less than 2.2 T.U. for

both Daphnia magna, a freshwater crustacean and the marine bacterium Vibrio fischeri. It is noted

that a toxic unit value of <3 is described as non-toxic. These results indicate that the discharge

from the Irish Cement Plant is non-toxic to two trophic levels. It is considered therefore that the

discharge from the Irish Cement plant to the River Nanny does not adversely affect the ecology of

River Nanny with respect to toxicity. In the way that lower trophic organisms are not affected by

the discharge, it is considered also that the discharge does not adversely affect fauna higher in

the food chain, such as macroinvertebrates recorded while biological sampling and fish supported

by these.

The dilution provided by the River Nanny would be expected to reduce any negative impacts, if

any of the discharge. According to Chapman (1995), different views in the form of tools such as

toxicity tests and field studies, together provide the best overall perspective. With regard to this

approach, it is also deduced from the macroinvertebrate field sampling that the discharge is Non-

Toxic.

SUMMARY AND CONCLUSIONS

The macroinvertebrate community and sediments at six sites located within 500m

upstream and downstream of the Irish Cement trade discharge outflow were investigated

during July 2012. These sites selected were at the same locations as in previous surveys

undertaken from 2008 to 2011.

The entire River Nanny was in an unsatisfactory ecological condition when most recently

monitored by the EPA in August 2010. The current river status of all watercourses in the

Nanny catchment are either 'Poor' or 'Moderate'. The problems in the River Nanny are

High Nutrient Concentration (Phosphorus, Ammonia, issues with level of oxygen in water

and Low Ecological Rating. The cause of these pressures have been identified as

agriculture, wastewater and industrial discharges and septic tanks. Pressures in the

Nanny are emphasised due to poorly drained soil leading to greater runoff (ERDB, 2010).

There was no distinct trend to imply that the Irish Cement trade effluent was impacting on

the substrate composition in the River Nanny, in particular smaller sized materials.

Substrates at all sites were found to be dominated by sands. The primary concern with

respect to the Irish Cement trade effluent is fine particles such as fine sands and silt/clay.

There is no evidence that the proportion of these finer particles is elevated downstream of

the discharge point. Indeed, there was a greater amount of silt/clay from the sample taken

nearest upstream of the discharge than in nearest sample taken downstream of same.

This is just an indication of normal sediment composition variation along the river, and

background hydrogeomorphological processes. Underwater observations of the river

coincided with the sediment results, where a considerable coat of silt was noted in the

river both upstream and downstream of the discharge point. The visual quality (clarity) of

trade effluent from the Irish Cement was seen be much greater than the River Nanny on

both days of the current survey. It is concluded that the trade effluent from the Irish

Cement Plant is not impacting on the composition of the substrate in the river.

The diversity and abundance levels of macroinvertebrates recorded at all sites were

considered to be typical of an organically polluted lowland Irish river. The

macroinvertebrate fauna was dominated by pollution tolerant organisms such as Asellus

aquaticus, green chironomid larvae and Chironomous sp. There has been a decrease in

family richness at the riffled reference site since 2011. Cased caddisfly larvae of

Limnephilus flavicornis, Athripsodes cinereus, Agapetus fuscipes and Phryganea

bipunctata were not recorded in the 2011 survey or in the current survey and damselfly

larvae has decreased in relative abundance since 2011.

Water pollution in the River Nanny continues to be problem with algal growths and

siltation obvious all along the surveyed stretch of the river. In 2011, the status of the river

was also found to be moderate, corresponding with EPA results. Since 2011, there

appears to have been a slight improvement in biological water quality, with the rating of

some sites rising to Q3-4. This improved rating is borderline however and was brought

about by the presence of a pollution sensitive mayfly larva at some locations, less

abundant macrophye growth than the previous year and relatively stable oxygenation

conditions. The higher than normal water levels that persisted throughout the summer are

thought to have influenced Q-ratings and other biotic indices.

The BMWP scores at riffled locations continue to be higher than expected, these scores

governed by family richness. In the current survey, there was an overall increase in

family richness compared to 2011 with the effect that all BMWP scores were greater than

100 (indicative of very good water quality). Using BMWP scores, there was no indication

that the trade effluent discharge was impacting biological water quality, the average

BMWP downstream of the discharge being 120 and 114 upstream. ASPT scores are

considered more robust and unambiguous than BMWP scores. ASPT scores throughout

the study area showed little variation but none were greater than 5.5 (scores equal to or

above reflective of good water quality). Chandler biotic index values at all sites were well

below the score of 80 (representative of unpolluted sites). The mean Chandler scores at

receptor sites and reference sites was 45.6 and 44.8 respectively. Trent biotic index

scores at all locations was 9. Based on family diversity, BMWP, Trent and Chandler

scores, there is no evidence to indicate that biological water quality is adversely affected

downstream of the Irish Cement trade effluent discharge point. Since 2011 there has

been an overall increase in BMWP scores. The highest score in the 2011 survey was at

Site N1 (124.5) compared to 136.7 Site N5 in the current survey.

The macroinvertebrate communities at receptor sites were collectively dominated by

filtering collectors while shredding macroinvertebrates were the most common functional

feeding group at the reference sites. Shredders specialise in the consumption of organic

matter deriving from inputs such as leaves. Changes in functional groups reflect changes

in food sources, nutrient processing and energy flow in the river system. The increase in

the relative abundance of shredders and the decrease in the relative abundance of

scrapers from 2011 signifies a shift away from primary instream production. This could

have been caused by the prolonged rainfall in the months preceding the survey, with

increased runoff from land and high water levels resulting in lower light intensity within the

water column and thereby reducing instream photosynthesis/primary production. The P/R

ratio at all sites examined was very low as in previous surveys. This indicates that the

River Nanny is highly heterotrophic. The scarcity of macroinvertebrate scrapers is a

reflection of unsatisfactory water quality and supporting habitats at all of the sites

investigated. In the current survey, there was no difference between reference and

receptor sites with regard to P/R ratios. This result indicates that there is no discernible

change in primary production taking place within the River Nanny downstream of the Irish

Cement discharge.

The functional group analysis results suggest that there is a ‘Predictable’ juvenile

salmonid food supply at all sites surveyed with the exception of the glide receptor site

(N4). This result was brought about by the generally high proportion of gathering

collectors (mainly E. ignita, Simulidae and green chironomids. Other factors such as water

quality, including siltation does not suit salmonid production in the surveyed stretch of the

river however.

Toxicology testing was carried out on two different trophic levels using trade effluent from

the Irish Cement plant. Toxicology test results showed that the effluent is non-toxic to the

organisms tested and it is considered that it is also non-toxic to macroinvertebrates in the

River Nanny. In combination with the results of the macroinvertebrate assemblages and

functional group analyses, it is considered that the discharge is not adversely impacting

aquatic ecology within the River Nanny.

The River Nanny is in the Eastern River Basin District. In the Programme of Measures for

the River Nanny Water Management Unit (WMU), the main pressure preventing

achievement of Good Status is diffuse agricultural and septic tank pollution (ERBD, 2009).

In this water management unit, naturally high levels of nutrients in the ground may also be

an issue. Full implementation of the measures is expected to correct this, however

recovery time will mean that larger rivers will not achieve Good Status before 2015. The

WFD recognises that in some cases it may not be possible to achieve all core objectives

by 2015. In cognisance of this, the target date for achievement of 'Good status' in the

River Nanny catchment has been set back to 2027.

The macroinvertebrate community along the surveyed stretch of river changes markedly

from year to year with only pollution tolerant indicators continuing to exist in successive

surveys. This changing state of the river is indicative of background pressures on aquatic

ecology, and not related to the Irish Cement discharge.

The trade effluent from the Irish Cement plant does not appear to be adversely affecting

BOD, hardness, Dissolved Oxygen (D.O.) in the River Nanny, as indicated by water

quality results from samples taken upstream and downstream of the discharge. In fact,

Dissolved Oxygen (D.O.) in the discharge was very close to 100%, the ideal saturation

concentration. Organic compounds and Heavy Metals were not present in the sample of

the discharge at a level considered harmful to the aquatic environment.

The results confirm that macroinvertebrate communities, biological water quality and

sediment levels in the River Nanny are not significantly different upstream and

downstream of the trade effluent from the Irish Cement plant. The discharge is considered

to be having a neutral impact on the aquatic ecology of local areas of the River Nanny.

4 RECOMMENDATIONS Biological monitoring of the River Nanny upstream and downstream of the discharge should be

continued to continue to monitor the impact of the discharge on aquatic ecology. Similarly, the

composition of substrates in the river should be assessed and Irish Cement Ltd. should continue

monitoring chemical water quality upstream and downstream of trade effluent discharge on the

River Nanny.

1 Executive Summary This report includes information on an energy efficiency audit conducted by Arup for Irish Cement Limited (ICL) at their cement production plant in Platin, Co. Meath.

The main findings of the report are as follows:

Kiln 3 which was commissioned in 2008 is a modern high efficiency plant which avails of the latest energy efficient technologies.

SRF (solid recovered fuel) was introduced as a fossil fuel substitute in March 2011. The introduction of SRF as part fossil fuel replacement in Kiln 3 uses material that otherwise would go to landfill.

A review of the overall site power consumption (kWhrs) for the years 2010 and 2011 shows a reduction of 7.5%.

ICL undertake continuous energy efficiency improvements. A register of energy efficiency improvement projects has been developed. Where these projects are found to make financial sense ICL provide funding for their implementation. This register is continually addressed and amended.

Overall site electricity and fuel consumption is tightly controlled. Continual measurement of kWh/tonne clinker and kWh/tonne cement are used to monitor process energy efficiency. Due to the commercially sensitive nature of their data this information could not be included in the report.

It is recommended that a Variable Speed Drive (VSD) is installed on the new 55kW limestone powder blower machine to reduce electricity consumption.

It is recommended to review the Power Factor Correction (PFC) equipment with a view to achieving possible electricity savings. .

It is recommended that a timeclock and a manual override switch are installed in the cement packing building to replace the current manual light switching.

It is recommended that a timeclock and a manual override switch are installed in the garage to replace the current manual light switching. It is also recommended to clean all rooflights in the garage for increased natural daylight.

It is recommended that a feasibility study is carried out as to the viability of using waste heat from Kiln 3.

It is recommended that a feasibility study is carried out as to whether improved controls on the Central Compressed Air plant can be utilised to better match the plant operation with varying process plant demand. It is also recommended that compressors are switched off during the weekend when not in use.

2 Introduction Arup were appointed by ICL, Platin, to carry out an Energy Efficiency Audit of their cement production plant in Platin, Co. Meath, in line with the Environmental Protection Agency Integrated Pollution Prevention Control (IPPC) requirements under Section G ‘Resource Use and Energy Efficiency’. This report is a summary of the main report for submittal to the Environmental Protection Agency (EPA) as part of the IPPC licence renewal documentation.

Arup visited the site on the 18 December 2012. The visit was facilitated by Seamus Breen, Oliver Farrell, David O’ Brien and Andrew Doyle of ICL.

There are approximately 100 employees in the Platin Plant. Approximately 85 employees were working on the site on 18 December when the site survey was undertaken.

The audit covers the period January to December 2012.

This report includes the following:

Table 1: Consumption of Different Energy Streams at the Site. Table 2: Final List of Audit Recommendations. An overview of the status of the existing energy management system at the

site. Overview of the energy performance indicators calculated for the site. A summary of the implications of audit findings.

3 Consumption of the Different Energy Streams

3.1 Site Energy Consumption Analysis The Energy performance of the site for 2010 and 2011 is provided in Table 1.

Year 2010 2011 Raw Material Usage (Tonnes) Limestone/Shale/Overburden 1,125,623 1,187,739 Bauxite/Iron Ore/Gypsum 78,072 70,243 Fuel Usage (Tonnes) Pet Coke/Coal 62,714 52,818 Diesel/Light Fuel Oil 1,340 815 Refuse Derived Fuel/Solid Recovered Fuel (SRF)

0 30,499

Electricity Usage (kWhrs) Electricity -7.5% Table 1 Energy Performance of the Site 2010-2011

The use of SRF, which would ordinarily go to landfill, is proving successful, with less reliance on fossil fuel sources.

The raw material usage on site has increased by 4% between 2010 and 2011 with a decrease of 8% in Electricity usage, demonstrating improving energy efficiency on site.

4 Final Audit Recommendations Table 2 on the following pages includes a final list of Audit Recommendations. For each recommendation the table includes a description of the measure, the predicted energy savings, emissions savings and payback period, the target date and the title of the person responsible for the implementation.

Investment Costs are categorised as either no/low cost, medium cost or high cost investments.

1 It is estimated that to supply and install a Variable Speed Drive will cost €15,000.00. However it is not possible to calculate an accurate payback period as the actual electrical load for the Raw Mill 3 distribution board is not available due to the commercial sensitivity of this information. Therefore it is not possible to calculate an accurate energy saving cost and payback period if a VSD is installed.

2 It is difficult to estimate what the cost savings will be once the Power Factor Correction System Units are re-viewed. The decision to replace PFCE is based on cost savings by avoiding the low power factor tariffs that may be imposed by the electricity supplier. It is impossible to know what savings can be achieved without the ICL conditions of supply with ESB Networks being available due to the commercial sensitivity of this information.

5 Overview of the Existing Energy Management System

Table 3 below outlines the status of the existing energy management system at the ICL Platin site. The Environmental Protection Agency (EPA) provides guidance on describing the different levels of implementation of an energy management system for an organisation. Based on a discussion with ICL Table 3 below describes the ICL energy management system on site at Platin3.

Energy Policy

Organising Motivation Information Systems

Marketing Investment

Energy policy, action plan and regular review have commitment of top management as part of an environmental strategy.

Energy manager accountable to energy committee representing all users chaired by a member of the managing board.

Formal and informal channels of communication regularly exploited by energy manager and energy staff at all levels.

Comprehensive system sets targets, monitors consumption, identifies faults, quantifies savings and provides budget tracking.

Programme of staff awareness and regular publicity campaigns.

Positive discrimination in favour of “green” schemes with detailed investment appraisal of all new-build and refurbishment opportunities.

Table 3 Status of the Existing Energy Management System at the Site

5.1 Energy Policy ICL implement energy efficiency improvements continually. The Engineering and Operations Department assess possible improvement projects from a technical and financial point of view. A register of energy efficiency improvement projects is developed and funding is provided by management. This is seen as core to achieving cost savings in the business and maintaining competitive advantage.

5.2 Organising A formal energy manager is not present on site. However all management, engineers and operations constantly monitor energy usage via the Key Performance Indicators (KPIs) of €/tonne of Clinker and €/tonne of cement produced. Management hold Engineers and Operations accountable should these KPIs increase above low target levels. These meetings to review the KPIs occur regularly.

3 This table is based on a table included in the EPA Guidance Note on Energy Efficiency Auditing. The EPA document sourced this information from the Energy Audit Templates of Sustainable Energy Ireland’s Pilot Programme on Negotiated Energy Agreements.



Page 9

5.3 Motivation From our meeting with the engineers and operations staff there appears to be regular meetings and communication during their daily course of work with a view to minimising energy usage on site.

5.4 Information System The cement production controls system monitors all energy usage and tracks KPIs automatically. Deviations from KPIs are noted as potential ‘faults’ or a need for operations to address. This information feeds into the preventative maintenance regime on site.

5.5 Marketing The ICL web site promotes their energy efficiency:

5.6 Investment The investment in energy efficient and green technologies where investment makes commercial sense are pursued continuously.

6 Energy Performance Indicators The process energy usage is tightly controlled. Constant measurement of the key performance indicators (KPIs) are -

€/Tonne of Clinker Produced €/Tonne of Cement Produced

Any process with a KPI below the target KPI is immediately investigated and a preventative maintenance procedure ensures all equipment is serviced to bring the KPIs back within target values.

Due to the commercial sensitivity of these KPIs a breakdown of the energy consumed and KPI records by process could not be included in this report. Benchmark data is not available from other cement production facilities also for the same reason so a comparative analysis could not be completed.

7 Summary of the Implications of the Audit Findings

This report includes information on an energy efficiency audit conducted by Arup for Irish Cement Limited (ICL) at their cement production plant in Platin, Co. Meath.

The main findings of the report are as follows:

Kiln 3 which was commissioned in 2008 is a modern high efficiency plant which avails of the latest energy efficient technologies.

SRF (solid recovered fuel) was introduced as a fossil fuel substitute in March 2011. The introduction of SRF as part fossil fuel replacement in Kiln 3 uses material that otherwise would go to landfill.

A review of the overall site power consumption (kWhrs) for the years 2010 and 2011 shows a reduction of 7.5%.

ICL undertake continuous energy efficiency improvements. A register of energy efficiency improvement projects has been developed. Where these projects are found to make financial sense ICL provide funding for their implementation. This register is continually addressed and amended.

Overall site electricity and fuel consumption is tightly controlled. Continual measurement of kWh/tonne clinker and kWh/tonne cement are used to monitor process energy efficiency. Due to the commercially sensitive nature of their data this information could not be included in the report.

It is recommended that a Variable Speed Drive (VSD) is installed on the new 55kW limestone powder blower machine to reduce electricity consumption.

It is recommended to review the Power Factor Correction (PFC) equipment with a view to achieving possible electricity savings. .

It is recommended that a timeclock and a manual override switch are installed in the cement packing building to replace the current manual light switching.

It is recommended that a timeclock and a manual override switch are installed in the garage to replace the current manual light switching. It is also recommended to clean all rooflights in the garage for increased natural daylight.

It is recommended that a feasibility study is carried out as to the viability of using waste heat from Kiln 3.

It is recommended that a feasibility study is carried out as to whether improved controls on the Central Compressed Air plant can be utilised to better match the plant operation with varying process plant demand. It is also recommended that compressors are switched off during the weekend when not in use.
