B.1 Emissions to Surface Waters

B.1.1 Process Emissions to Surface Waters

Process emissions to the WWTP consist of;

� Fermentation 1

� Fermentation 2

� Purification 1

� Purification 2

� Formulation

� Laboratories

� Cooling towers, boilers blowdown

� Boiler House

Any drains present in the process areas drain to the WWTP on site. Sanitary waste is also directed to the

WWTP where physical, chemical and biological treatment is provided. The effluent from the WWTP is

discharged under license into the Bandon River Upper Estuary approximately 700m north of Kilmacsimon via

an approximately 9km long pipeline. From when it leaves the facility, the pipeline is buried and follows local

roads in a southerly direction. The pipe passes under the road through Innishannon village and crosses the

Bandon River via Innishannon Bridge. The pipe continues in a southerly direction, following the course of the

Bandon River and then into the estuary at Colliers Quay (SW1). At this point it is laid on the surface of the

intertidal area of the estuary on concrete footings for 2km. During low tide sections of the pipeline are visible.

The final ~30m of the pipe is located towards the centre of the estuary channel and the outfall point is always

submerged. There is a diffuser system at the outfall which helps disperse the effluent.

The highest point on the route is approximately 2km from the plant. Two pumps are used to pump the

effluent to this point. When the pumps are on the pumping pressure results in the effluent flowing in the pipe

at greater velocity than when the pumps are off. When the pump is switched off the effluent remaining in the

pipe beyond the highest point drains down under gravity to the outfall diffuser. There are non return valves

that prevent the pumped effluent flowing back to the WWTP.

An interactive monitoring and management software package, SCADA, administers the WWTP operations. As

part of the WWTP management it is programmed to automatically control the discharge pumping times of the

effluent to the pipeline. A tidal clock is incorporated into SCADA system and is used, together with data input

by Schering Plough personnel, to schedule the automated pumps on/off times. The system contains an

automatic alarm. Flow meters are installed at the Brinny site and Colliers Quay. The flow meters’ flow times

and pumps on/off times are analysed weekly to retrospectively confirm no effluent is discharged within 45

minutes before and after tide turn times. Daily flow comparisons are also carried out on the flows recorded

from the flow meter on the Brinny site and the flow meter at Colliers Quay to ensure that no discrepancies

occur.

B.1.2 Non Process Emissions to Surface Waters

Storm water run-off is directed to surface water drains which discharge to the Brinny River via an interceptor

and a TOC/pH/Temperature monitoring chamber (SW2). Reverse osmosis concentrate also discharges to the

surface water drains. The system is set up to re-route the storm water if TOC/pH/Temperature levels exceed

specific limits. Also under a continuous fire alarm security activate the storm water diversion valve which

diverts the storm water drainage to the fire water retention pond.

B.1.3 Emissions to Surface Waters - Summary

Figure 7 shows the location of the surface water emission point SW2 and the final effluent monitoring point

SW1A. Figure 8 shows the location of surface water emission point SW1. The receiving waters are located in

the Upper Bandon Estuary and are influenced by tidal waters. The saline concentration of the receiving water

is dependant on the tide and the volume of freshwater flowing from the River Bandon Catchment. When the

tide is ebb (rising) then the waters will have a higher saline content than when the tide is flowing (falling).

Typically the salinity range for estuarine waters is 0 - 17% saline.

Details of the emissions to surface water are summarized in Table B.1(i) on the application form.

List II Substances; List II is defined in EU Directive 76/464 EEC Annex as substances belonging to the families

and groups of substances in List 1 for which limit values have not been determined and a list of substances or

categories of substances belonging to families and groups of substances in a list provided. The List II

materials used on site which are deemed to fall within the above definitions are;

� Trichloroacetic Acid (TCAA)

� Nitrogen (Nutritive Compounds)

� Phosphorus (Nutritive Compounds)

A List II Substances Reduction Report is prepared annually as part of the Annual Environmental Report. In

relation to the reduction in TCAA this is not considered to be a practical option. The treatment system

installed is BAT. Test results of TCAA measurements are generally less than the analytical method of detection

level (0.1 mg/l). Work is concentrated on ensuring that the effluent TCAA is consistently below the level of

detection by ensuring that all TCAA wastes are routed to the TCAA treatment system.

The system installed for nitrogen reduction is BAT. This is a biological nitrification/de-nitrification system. The

system is meeting the design removal parameters. Nitrate discharge in 2010 had a removal efficiency of

81.7%.

The primary phosphorus removal method in use is the precipitation of orthophosphate by lime to give

insoluble calcium phosphate. This pre-treatment method has been shown to be more effective than post

treatment precipitation. Further phosphate removal is obtained by phosphate uptake in the activated sludge

system. Phosphate discharge in 2010 in wastewater had a removal efficiency of 96.7%. This system is BAT.

B.3 Emissions to Sewer

There are no emissions to sewer from the facility, all process and non process water is directed to the WWTP

for treatment and discharges to surface water.

B.4 Emissions to Ground

There are no direct process emissions to groundwater. There are four soak pits on site which take rainfall

run-off from the carpark and hardstanding areas, two to the east of the car park and one to the west of the

car park. The fourth soak pit is located west of Building No. 21. Petrol interceptors are located on the

drainage system to all of the soak pits. Boreholes on site facilitate groundwater monitoring.

CONTROL & MONITORING

C.1 Surface Water – Treatment, Abatement and Control Systems

C.1.1 Process Water – Treatment, Abatement and Control Systems

All drains present in the process areas drain to the WWTP on site. Sanitary waste is also directed to the

WWTP where physical, chemical and biological treatment is provided. The effluent from the WWTP is

discharged under license into the Bandon River estuary approximately 700m north of Kilmacsimon via an

approximately 9km long pipeline.

An interactive monitoring and management software package, SCADA, administers the WWTP operations. As

part of the WWTP management it is programmed to automatically control the discharge pumping times of the

effluent to the pipeline. A tidal clock is incorporated into SCADA system and is used, together with data input

by Schering Plough personnel, to schedule the automated pumps on/off times. The system contains an

automatic alarm. Flow meters are installed at the Brinny site and Colliers Quay. The flow meters’ flow times

and pumps on/off times are analysed weekly to retrospectively confirm no effluent is discharged within 45

minutes before and after tide turn times. Daily flow comparisons are also carried out on the flows recorded

from the flow meter on the Brinny site and the flow meter at Colliers Quay to ensure that no discrepancies

occur.

C.1.1.1 WWTP Plant Overview

The WWTP is designed to cater for the following;

� The breakdown of TCA in fermentation wastewater streams by reacting at high temperature in a high

pH caustic soda environment, capable of operating at flow rates between 100 and 1000 litres per hour

(l/hr).

� The precipitation of phosphates from fermentation wastewater streams by reaction with lime and

subsequent pH correction with HCL and flocculation by the addition of polyelectrolyte solution.

� The balancing of flow from the facility so that minimum and maximum flows can be catered for, up to

33m3/hr through the plant.

� The removal of BOD from all wastewater streams including contaminated surface water in a biofilter

and an extended aeration system. The design maximum flow rate through the treatment plant is

34m3/hr average over 24 hours, or a total of 800m3/day.

� The removal of nitrogen from the wastewater by means of a nitrification/denitrification process

involving selector, anoxic and extended aeration tanks.

� The settlement and collection of sludge in a number of settlement tanks.

� The collection of sludge for thickening and dewatering on site or for removal off site.

� The discharge of treated effluent to the Bandon River.

C.1.1.2 Overview of TCA Degradation System

A number of wastewater streams on site contain residual quantities of TCAA (Trichloroacetic acid). A strict

discharge limit on the material has been given in the existing licence therefore a system to degrade TCAA is

necessary.

In order to achieve the breakdown of TCAA, the following process operations take place;

� TCAA wastewater is collected and stored in one or other of two storage tanks (4T104 and 4T140).

� TCAA wastewater is pumped forward from one or other of these tanks at a flow rate varying between

200l/hr and 1000l/hr.

� Caustic soda is dosed in line into the TCAA wastewater. The rate of dosing is dependent on the TCAA

wastewater flow rate, % TCAA in the wastewater and % phosphate in the wastewater.

� The caustic and TCAA streams are mixed thoroughly on line in a static mixer.

� The liquid is heated to within 5°C of reaction temperature in a shell and tube heat exchanger. This heat

exchanger is vented so that any gases which may be liberated can be released to the head space of the

reactors.

� The heated liquid then passes to the reactors. There are two 1000ltr reactors in series. Both reactors

are agitated to give mixed flow conditions in the reactors. At start up the reactors are filled and reacted

to completion for a period of time. When reacted to completion, continuous operation commences and

should be capable of running for several days without interruption.

� Within the reactor, pressure is maintained by a combination of a vent valve which will release small

quantities of air/gas from the reactor head space should the pressure tend to rise, and a compressed

air inlet valve which will allow compressed air in to bring the pressure back up should the pressure tend

to fall.

� A mechanical pressure relief valve will provide back up security in the (unlikely) event of an excessive

pressure build up.

� Normal releases from the vent valve are discharged to a water bath so that any foam or liquid carry

over can be dealt with safely. This water bath is covered with a water seal on the liquid discharge and a

vent pipe to a safe height for any gas release. Any foam/liquid discharges from the safety valve are

piped to the same water bath.

� The reacted liquor flows from the reactor to a cooling plate heat exchanger.

� The flow rate to the reactors must balance the flow from the reactors. To ensure this a control valve on

discharge from the regenerator modulates to maintain a set liquid level in the reactors.

� After the level control valve a pair of valves can be set to feed the liquid forward to the phosphate

precipitation system, or divert flow back to the storage tanks (4T104/4T140). Normally the flow is

forward. However, in an emergency, where the wastewater has not reacted or where some fault has

occurred the flow can be diverted back to tanks 4T104 and 4T140.

The continuous flow rate through the system may be varied between 200l/hr and 1000l/hr. From a plant

control side, procedures for shut down are included such that if certain parameters vary outside set limits the

plant will go into a ‘hold’ mode.

C.1.1.3 Overview of Phosphate Precipitation System

The reacted TCAA liquor is fed forward for phosphate precipitation. This process involves the addition of lime,

pH correction and polyelectrolyte dosing followed by clarification of the lime phosphate in the primary

settlement tank.

Under normal conditions the reacted liquor feeds forward to the lime addition tank (4T105). Lime is dosed at

a rate proportional to the forward feed flow and related to the phosphate content of the liquor. An agitator in

this tank keeps solids in suspension. A gravity discharge from the overflow ensures that the rate of inflow and

outflow are equal.

Lime is stored in a bulk silo adjacent to the metering hopper. Level probes on the metering hopper act to

initiate transfer of lime to a slurry tank as required. Lime slurry at 15% w/w concentration is pumped to

4T105 tank.

The overflow from the lime reaction tank discharges to the acid/poly tank. Acid is dosed into the first section

for pH correction. This section of the tank contains an agitator to ensure good mixing. A pH meter monitors

and controls the pH of the liquor in this tank. The acid dosing pumps feeding this tank have variable speed

drivers which increase or decrease the dosage rate of acid in order to maintain a constant pH in the tank.

After acid dosing the liquor flows into 4T106 where a solution of polymers is dosed into the wastewater just

at the inlet of the tank at a constant rate.

The overflow from 4T106 is fed to the pH correction tank V400 or to the Factory waste pump sump.

The overflow from V400 is fed to Splitter Chamber 1 or to Settlement Tank 4T112. In the de-sludge process

the transfer of the centrates from the settling tanks T112 is controlled by two sequences. The first sequence

sends the centrates to the V400 pH correction tank while the second sequence recirculates the centrates back

into the T112 settling tank.

C.1.1.4 Overview of Biological Treatment System

The biological treatment plant collects wastewater streams as follows;

� Sanitary wastewater in the sanitary pump station (4T101)

� Facility wastewater and contaminated surface water in the facility pump station (4T102). The

supernatant from the primary settlement tank (4T106) also flows to 4T102. Facility waste from

fermentation is pumped direct to the balance tank

� Reacted TCA liquor direct from 4T140, following pH correction and phosphate precipitation in primary

settlement tank 4T106

The wastewater stream from the sanitary sump is pumped forward to the biofilter feed sump (4T109). The

pumping is controlled by level probes. The wastewater from the facility sump is pumped to the balance tank

(4T142), pumping is controlled by level probes.

The balance tank has a total volume of 800m3 divided into two cells of equal size. The purpose of the balance

tank is as follows;

� It can take surges of wastewater flow over short periods of time and balance this flow over 24 hours to

the downstream treatment plant.

� HCL and caustic soda are dosed as required into this tank, to maintain the required pH limit of 7.0 –

8.5.

Pumped flow from the balance tank is directed to Splitter Chamber No. 1. From this chamber the flow is

directed to the forward feed sump. A portion of the flow may be directed to the activated sludge process to

provide a readily degradable carbon source for denitrification. Under low loading conditions most or all of the

flow will be directed to the activated sludge process.

Sludge accumulates in settlement tank 4T116 and sludge pumps operate on a timer basis as set by the

SCADA system. The sludge is pumped to the sludge thickening tank, 4T118B. The flow goes to the Splitter

Chamber No. 2 adjacent to the selector and anoxic tank.

C.1.1.5 Nitrification / Denitrification Process

Splitter Chamber No. 2 is located adjacent to the selector and anoxic tanks. Flow from the forward feed sump

discharges to this sump. A manually operated weir sends part to the selector tank and the remainder to the

anoxic tank.

Of the wastewater flow to the extended aeration tanks, some goes first to the selector tank and then to the

anoxic tank, while the remainder goes directly to the anoxic tank. The flow from the anoxic tank then

discharges to the extended aeration tanks. The function of the selector tank is to provide environmental

conditions to favour the growth of the necessary floc forming micro-organisms.

The purpose of the anoxic tank is to provide an environment with sufficient carbon source (BOD) and no

available dissolved oxygen. Under such conditions facultative heterotrophic bacteria will convert nitrate

essentially to nitrogen gas and carbon dioxide, thereby denitrifying the wastewater.

Flow from the anoxic tank is split equally between two extended aeration tanks. The aeration tanks provide

an environment with dissolved oxygen level typically between 1-2mg/l. Such conditions favour growth of

aerobic bacteria. These bacteria perform two functions; reduction of BOD (Heterotrophic bacteria) and the

conversion of ammonia to nitrate (autotrophic).

The discharge from both aeration tanks flows to the nitrified wastewater recirculation sump. The nitrified

wastewater is circulated back to the anoxic tank for de-nitrification.

The overflow from the nitrified wastewater recirculation sump discharges to the Final Clarifier (4T121). The

supernatant from this settlement tank discharges by gravity to the final effluent holding tank (4T117). Sludge

will accumulate in the bottom of 4T121 and is gravity fed to the waste sludge tank 4T149. Sludge is normally

pumped back from the waste sludge tank to the selector tank 4T144. However it will be necessary to waste

the sludge density within the activated sludge process tanks. The amount of sludge wasted will depend on the

loading of the plant. This wasted sludge is directed to the sludge thickening tank 4T118B.

The final effluent tank 4T117 will accumulate the treated wastewater prior to discharge to the River Bandon.

pH and temperature in this tank is monitored and recorded. The discharge is controlled as discussed in

Section C.1.1.

C.1.1.6 Sludge Treatment

There are three sludge storage/thickening tanks 4T118A, 4T118B and 4T119. The lime sludge storage tanks

4T118A and 4T119 receives sludge from the primary settlement tank 4T106 following TCA treatment. The bio

sludge thickening tank 4T118B receives sludge from the waste activated sludge pump sump 4T149 adjacent

to the final clarifier 4T121 and from the settlement tank 4T116. The supernatant from 4T118A and 4T118B is

returned to the factory waste pump station 4T102 for further re-circulation through the treatment works. The

sludge from all three tanks is fed in rotation to the sludge dewatering system.

Waste sludge from all three sludge storage/thickening tanks is pumped to the sludge dewatering system. The

filtrate from the dewatering plant is fed into 4T160 from where it is pumped back to Splitter Chamber 2. The

final sludge is collected in a skip for off site disposal.

C.1.2 Non Process Water – Treatment, Abatement and Control Systems

Storm water run-off is directed to surface water drains which discharge to the Brinny River via an interceptor

and a TOC/pH/Temperature monitoring chamber (SW2). Reverse osmosis concentrate also discharges to the

surface water drains.

The storm water system is equipped with a continuous TOC/pH/temperature monitor. The system samples on

a continuous basis all water passing through the storm water monitoring chamber. The outputs of the

TOC/pH/temperature meters are connected to alarms which feed back to the SCADA system for the WWTP.

Any alarm will automatically trigger the operation of a diversion system to the firewater collection pond and

alarm at the SCADA for the particular monitoring and sound an alarm at the security office. Following further

confirmation testing of the firewater pond contents appropriate action may be taken to;

C.2 Monitoring and Sampling Points

C.2.1 Surface Water Emission Monitoring and Sampling Points

Monitoring will continue to be carried out at the various stages in the wastewater treatment process as

follows;

� TCAA removal stage involves monitoring for waste flow, caustic flow, pH, TCAA concentration,

temperature and reactor level control.

� Biological treatment stage involves monitoring for pH, flow/feed rate, dissolved oxygen (nitrification),

dissolved oxygen (denitrification), settlement, mixed liquor suspended solids, flood/micro-organisms

ratio, sludge volume index, sludge floc microscopy, pH (final effluent).

� Phosphate removal stage involves monitoring for waste flow, phosphate concentration, lime addition,

acid neutralization, flocculation.

� Final effluent stage involves monitoring for flow, pH, COD, BOD5, suspended solids, kjeldhal nitrogen,

nitrate, ammonia, TCAA, total phosphorus, total zinc, solvent and toxicity.

SW1A denotes the above monitoring of the final effluent and is shown on Figure 7. To note Figures 8 and 9

show the location of the surface water emission point SW1 which as described in Section C.1.1 is the effluent

from the WWTP which is discharged into the Bandon River estuary approximately 700m north of Kilmacsimon

via an approximately 9km long pipeline.

Non process surface water will continue to be monitored on a continuous basis for TOC/pH/temperature at

SW2 as shown on Figure 7.

C.2.3 Wastewater Emission Monitoring and Sampling Points

There are no emissions to sewer from the facility, all process and non process water is directed to the WWTP

for treatment and discharge to surface water.

C.2.4 Groundwater Emission Monitoring

There are no emissions to groundwater from the SP facility at Brinny. Groundwater monitoring will continue to

be carried out on an annual basis for trace organics and on a bi-annual basis for major anions, major cations,

ammonia (as NH3), nitrate (as N) and individual heavy metals seven monitoring wells located around the

facility.

1 Introduction

WYG Environmental & Planning (Ireland) Ltd., (WYG) were appointed by Schering Plough (Brinny) Ltd (SP)

to undertake ‘Simple Assimilative Capacity Modelling’ for some of the parameters that the site is licensed to

discharge to the transitional waters of the Bandon River as part of their IPCC licence (P0005-01), reference

P0005-02.

1.1 Background

The report is part of a review being undertaken for the Environmental Protection Agency (EPA) of SPs

compliance with the European Communities Environmental Objectives (Surface Waters) Regulations (2009)

- SI No. 272 of 2009. (EO Regulations).

SPs treated process water discharge point is located at Shipool, on the Bandon River, close to Kilmacsimon.

This section of the Bandon River is considered to be transitional as defined in the EO regulations:

“transitional waters” are bodies of surface water in the vicinity of River mouths which are partly saline in

character as a result of their proximity to coastal waters but which are substantially influenced by

freshwater flows.

According to the National Parks and Wildlife service online database, the SP discharge point is located

within a proposed Natural Heritage Area (pNHA) that runs from Colliers Quay to approximately 1km

downriver of Kilmacsimon. A second pNHA is located 12.5km downstream around the James Fort headland

opposite Kinsale town.

The model used for the calculations is based on the EPA guidance document for the ‘EO Regulations Review

– Simple Assimilative capacity model for transitional waters’ which is available at the following link:

http://www.epa.ie/downloads/advice/general/name,31177,en.html

Based on the EC EO (surface Waters) Regulations (SI 272 of 2009), Schedule 5, the parameters that

require an assimilative capacity assessment, based on the process water discharged under licence from SP

are:

� Biochemical Oxygen Demand (BOD)

� Molybdate Reactive Phosphorous (MRP)

� Dissolved Oxygen (DO)

� Zinc (Zn)

Information on the location of the licensed SP Surface Water Emission Point (SW1) is provided in Sections B

and C of the Review Report of which this report is Attachment D.1.

2 EPA Assimilative Model for Transitional Waters

The EPA have provided simple assimilative capacity models for transitional waters to allow IPPC facilities to

assess their licence’s compliance with the EO Surface Water Regulations 2009 as mentioned above.

The model estimates, for a given discharge parameter, the resultant concentration in a receiving waterbody

which has freshwater and saltwater inputs. Using the salinity values of the ‘open’ water and in the vicinity

of the discharge, it estimates the flow of dilution water (i.e. seawater and freshwater inputs) within the

estuary. This figure is then divided in to the receiving waters.

The salinity value at the discharge point has been determined by SP from sampling analysis during surface

water monitoring at the discharge point SW1. An average of the previous 12 rounds of sampling has been

used.

The model formula for calculating the flow of available dilution water (Qd) is as follows:

Qd = (Qe + Qf) So/ (So-S)

where Qe is the flow rate of licensed discharge (m3/s)

Qf is the 95%ile flow rate of the river (m3/s)

So is the salinity of the open water

S is the salinity of the water in the vicinity of licensed discharge

Once the value for Qd is established it can be substituted into the following formula to calculate the

concentration (C) of a given discharged substance in the receiving water:

C = Cb + (Ce - Cb)/ (1 + (Qd / QL))

where QL is the maximum flow of the discharged substance allowable

under the licence.

Cb is the background concentration

Ce is the effluent discharge concentration

Note that Dissolved Oxygen (DO) is not monitored in the discharge effluent and there is no DO ELV for the

facility. To evaluate the impact that DO within the discharged process water would have on the receiving

water, values of 0% and 100% are modelled.

Section 2.1 below discusses the various data inputs for the model. Tables D1.1 to D1.6 present the model

calculations for the assimilative capacity calculations. Sections 2.2 to 2.5 discuss the findings of the

assimilative capacity modelling for MRP, BOD, DO and Zinc.

2.1 Model Input Data Sources

2.1.1 IPPC Licensed Emission Flow rates

The maximum licensed flow rate from the WWTP is 800m3/day (0.00926m3/sec). This value is used to

represent QL in the equation above).

The actual discharged total volumes (m3) for 2009 and 2010 as presented in the 2010 AER for Schering

Plough (see copy of page 9 from SP AER in Appendix A of this report). When these volumes are reduced

to m3/sec they are 0.005205m3/sec and 0.00546m3/sec for 2009 and 2010 respectively. These values

represent Qe in the model.

2.1.2 95%ile Flow of Water

The closest EPA monitoring station to the Discharge point SW1 on the River Bandon is at Curranure, located

at National Grid ref W529 571. This station has a 95%ile flow rate of 1.33m3/sec. Information on the

station is attached in Appendix B in this report.

The station is located upriver of the confluence of the Brinny River with the Bandon. The catchment for the

Brinny is 72km2 compared to the Bandon catchment of 431km2 (at the Curranure Station). These values are

provided in a report carried out for SP on a Dye Tracing Test carried out for SP as part of an EIS completed

in 1992 on the discharge point SW1. The relevant pages of this report are included in Appendix C of this

report. In order to calculate the approximate 95%ile flow rate to include the Brinny River flow the following

calculation was completed:

(1.33/431)*(431 + 72) = 1.55

Therefore the 95%ile flow rate used in the assimilative capacity model is 1.55m3/sec.

2.1.3 Salinity Values

The salinity of transitional waters varies significantly depending on how close to the coastal zone the

samples are taken. The discharge point SW1 is located within the Upper Bandon Estuary which is

delineated by the EPA as between Innishannon Bridge and Kinsale Bridge. This is a long expanse of water

which has a significantly varying saltwater influence. The Discharge point SW1 is located close to the upper

reaches of the tidal regime, close to Shipool. As part of SPs monitoring regime the water salinity is

monitored during each sampling round. In order to provide as accurate a model as possible the average

value for salinity for the previous 12 monitoring rounds (2011 – 2008) has been used provide a salinity

value for the water at the discharge point. This is considered to be a more realistic input than the value

derived from the EPA data for the salinity values for the Upper Bandon Estuary.

2.1.4 Ambient Background Sampling & Background Levels

SP have a compiled a database of surface water sampling results for ambient environmental monitoring

from six locations on the Bandon River including the Discharge point SW1 since 1984. Three sampling

points are located upriver of the discharge point (SW1) at Innishannon Bridge (named Dundaniel), Colliers

Quay and Shipool Castle. There are two sampling points located downstream of SW1 at Rock House and

Kilmacsimon. All sampling locations are mid-stream and no samples are taken during a 45 minute window

either side of High and Low Tides. Figure 9 in the main report shows these sampling points. The database

of results is presented in Attachment C.2.5 of the main report.

For the purposes of inputting background concentrations into the model WYG, where applicable, used the

available values for the Upper Bandon Estuary from the EPA Water Quality in Ireland 2007 – 2009 Report.

This data gives Median MRP Values for Winter of 0.031mg/l and for Summer of 0.024mg/l. The EPA MRP

value used to compare against the threshold value is 0.024 mg/l and this value is used as the MRP

background value. The BOD summer median value is given as 2.3mg/l, as there is no winter data this

summer value is used as the background value. DO values of 82.0% for the 5 percentile saturation and

160.6% for the 95 percentile saturation are given. Refer to the EPA data for the Upper Bandon Estuary in

Appendix D of this report. For Zinc a background value was taken from the Marine Institute 2011 Report

on the quality of Irish Marine Waters, Refer to Appendix E of this report. No ambient sampling is

competed by the site for Zinc.

As a cross check WYG also looked at the ambient sampling data gathered by SP and calculated the average

of the last 8 - 12 samples (taken between 2008 and 2011) from the sampling point located upriver but

closest to SW1, which is Shipool Castle) to use as a comparison to the EPA background concentration.

Therefore the background values used in the model are as follows:

MRP: 0.024mg/l. From the published EPA value. Note that the calculated ambient background value is

0.02mg/l which is calculated from the average of the last eight SP samples as prior to September 2009 the

laboratory Limit of Detection (LoD) was <0.16mg/l which is in exceedence of the required concentration of

MRP in the river and would negatively skew the average if included.

BOD:2.3mg/l. From the median EPA Summer value. Note this is the same value calculated from the SP

ambient sampling data where only two of the 12 samples taken between 2008 and 2011 had levels of BOD

that exceeded the LoD of 2mg/l.

DO: 96.23% Saturation. This is the average of the last 12 SP samples which were used to calculate an

ambient background DO saturation.

Zn: 0.0342 mg/l. From Table B.1 of the Marine Institute 2011 Report on background trace metal values

in Irish Sea Waters.

2.2 Molybdate Reactive Phosphate (MRP)

Molybdate Reactive Phosphate is often referred to as orthophosphate (PO4) and is recorded as phosphate

(P) in surface water monitoring. The SP facility is licensed to discharge up to 10mg/l of Total Phosphate (P)

from the WWTP in the process water emissions to SW1. MRP is one component of this and as such is

included in the Total Phosphate limit set by the license.

The 2010 AER indicates that actual emissions of Total Phosphate from the discharged process water for

2009 and 2010 are 0.37mg/l and 1.52mg/l respectively which are considerably lower than the ELV.

The EO regulations (surface waters) SI 272 of 2009 state that the MRP requirement for transitional waters

with salinity values of 0-17psu is 0.060mg/l. The salinity value at the discharge point SW1 is 10.84psu.

The assimilative capacity model was run using Total Phosphate concentrations as conservative values and

using background values of PO4 as recorded by SP in the ambient surface water sampling completed since

1984.

Tables D.1.1 to D.1.3 show the assimilative capacity model results for the ELV concentration, the 2009

discharged concentration and the 2010 discharged concentration of Total Phosphate respectively. Table

D.1.1 shows the results of the assimilative capacity of the receiving water using the ELV of 10mg/l (Total

P). The result indicates a concentration of 0.065mg/l which is 0.005 above the limit allowed by the EO

regulations. However, actual discharged concentrations of Total Phosphate in the process water were

significantly lower than the ELV and models were also calculated with the emissions data from 2009 (Table

D.1.2) and 2010 (2010 AER). The receiving water concentrations of MRP were 0.025mg/l in 2009 and

0.030mg/l in 2010. These concentrations are within the EO limit of 0.060mg/l for transitional waters.

The existing ELV of 10mg/l is required for the facility to allow for potential periodic short duration

fluctuations in the effluent emissions that could arise due to changes in the production schedule of the

facility, in particular fermentation processes.

2.3 BOD (Biochemical Oxygen Demand)

The IPPC Licensed emissions for BOD in discharged process water from the WWTP is 50mg/l. The 2010

AER states that the actual annual emissions for 2009 and 2010 were 7mg/l and 4.8mg/l. Conservatively the

licensed concentration (50mg/l) was input into the model calculations and the concentration of BOD in the

River Bandon was modelled to be 2.493mg/l (See Table D.1.4).

The BOD Limit for transitional waters as outlined in the EO regulations (surface waters) 2009 is ≤4.0mg/l

and the receiving water concentration is within this limit at the discharge point SW1.

2.4 Dissolved Oxygen (DO)

Dissolved Oxygen values are not recorded in the effluent and there is no ELV in the SP IPPC License for DO.

The EO Regulations give a DO lower limit of 95%ile >70% saturation (for waters with a salinity value of

0psu) and upper limit of <120% saturation (coastal waters - salinity value 35psu) for transitional waters. To

estimate the effect that Do in the discharged process water would have on the receiving water values of

0% and 100% saturation have been applied to the discharged emissions (Tables D.1.5 and D.1.6).

The results indicate that the DO concentration in the receiving water ranges from 92.88% to 93.29%

saturation which is within the water quality requirements of the EO regulations for DO in transitional

waters.

2.5 Zinc (Zn)

The only metal parameter that is monitored by the site and has an ELV in the IPPC Licence is Zinc, as this

was once an ingredient required for a product that was previously manufactured by the Brinny facility.

Applying the relevant formula for the assimilative capacity in Transitional Waters, using background

concentration from Mean Sea Water value (0.0342mg/l) from the Marine Institute 2011 Report and the

sites ELV of 0.5mg/l the calculated concentration of the discharged substance in the receiving water is

0.036mg/l. This is below the AA-EQS threshold level of 0.04mg/l given in the regulations for ‘other waters’

including transitional and coastal environments.

It should be noted that since zinc is not used as a main ingredient in the products manufactured on the

Brinny site the actual monitored values of the parameter in the effluent discharge waters, as reported in the

AER, are at values of 0.065mg/l in 2009 and 0.070mg/l for 2009 and 2010 respectively which are well

below the ELV of 0.5mg/l.

3 Conclusions

The SP emission point SW1 is located in transitional waters close to Shipool at NGR 156305 54317 in the

Upper Bandon Estuary which is currently given a ‘Eutrophic’ water quality status by the EPA under Water

Framework Directive. The IPPC License permits a maximum flow rate of 50m3/hr for the SW1 emission

point. The relevant river quality calculations for discharges from SP are MRP, BOD, DO and Zn. There are

no ELVs for DO or MRP in the SP IPPC License. For the purposes of this report the assimilative capacity

modelling was completed using the Total Phosphate concentrations in the process water discharged as

conservative values for MRP and values of 0% and 100% saturation of DO to estimate the effect of DO

within the process water discharged from the site would have on the receiving water quality.

Background values for MRP, BOD and DO were taken from the EPA Water Quality Report 2007 – 2009 and

for comparison ambient background values were calculated form the SW analysis carried out by SP since

1984 at a location upriver of the discharge point SW1.

The background value for Zinc was taken from the 2001 Marine Institute Report on Marine Water Quality.

No Zinc monitoring is done as part of the ambient water sampling completed by SP.

The use of the EPA Assimilative Capacity Equations with the data acquired for the SP emission point SW1

indicated that:

If the ELV for Total Phosphate is applied to the discharge water as MRP the assimilative capacity of the

receiving water with an EPA derived background level 0.024mg/l will give a concentration of 0.065mg/l

which is just above the EO limit of 0.060mg/l for transitional waters. However, when the average ambient

background values of 0.02mg/l is used the EO limit 0f 0.060 is matched and when the actual discharged

concentrations from 2009 and 2010 are applied to the model the receiving water concentrations of MRP are

within the EO limit. The ELV of 10mg/l is required to for potential fluctuations in the effluent emissions that

can arise due to changes in the production schedule of the facility, in particular fermentation processes.

The ELV level for BOD of 50mg/l does not cause an exceedance in the EO limits for transitional waters.

DO levels in the receiving waters do not significantly change when using concentrations of either 0% or

100% saturation and DO levels are within the EO limits for transitional waters.

Zinc concentrations in the receiving waters are calculated to be lower than the EO AA-EQS Threshold of

0.04mg/l when the ELV emission value of 0.5mg/l is applied to the EPA equation. The sites actual emission

concentrations for Zinc are well below the ELV value.

ATTACHMENT D.2

D.2 Environmental Considerations and BAT

D.2.1 Introduction

For the purpose of this application, reference is made to the BAT Guidance Note on Best Available Techniques

for Pharmaceutical and Other Specialty Organic Chemicals, Environmental Protection Agency 2008 (referred to

as the BAT Guidance Note for the purpose of this section). This BAT Guidance Note covers the facility as it

falls within the following class of activity:

5.6 The manufacture of pesticides, pharmaceutical or veterinary products and their intermediates.

Note: Reference is also made to the BREF Integrated Pollution Prevention and Control (IPPC) Reference

Document on Best Available Techniques for the Manufacture of Organic Fine Chemicals, published by the

European IPPC Bureau in December 2005 (referred to as the BREF Document for the purpose of this section).

D.2.2 Description of Process

The facility produces a range of protein based biotechnology products for human pharmaceutical use. The

products currently produced are;

� Intron in the form of injectable vials or a multidose pen for the treatment of Hepatitis C and Cancer

� PEG Intron in the form of injectable vials for the treatment of Hepatitis C and Cancer

� Remicade in the form of injectable vials for the treatment of Crohn’s disease and Arthritis

Trials and validation studies for new products such as Sugammadex and Posaconazoleiv are also carried out

involving one or more stages of production at the facility. At present these products are not produced for

commercial sale.

Generally similar processes produce all the biotechnology products manufactured at the facility. These

processes are;

� Fermentation / Recovery

� Purification

� Formulation

D.2.3 Risk to the Environment

The BAT Guidance Note highlights the key environmental issues of the pharmaceutical sector as;

� Emissions of volatile organic compounds

� Waste waters with potential for high loads of non-degradable organic compounds

� Large quantities of spent solvents

� Non-recyclable waste in high ratio

D.2.3.1 Emissions to Air

Combustion gases such as NOx and SO2 are considered as part of the emissions to air. There are no emissions

of volatile organic compounds from the process. Section 2.4.2.1 of the BREF Document gives an overview of

the main sources and pollutants of waste gas emissions, although SO2 and NOx are listed as pollutants the

source at the facility does not fall under any specific source listed in the BREF Document.

D.2.3.2 Emissions to Water

All process and sanitary/foul effluent undergoes various physical, chemical and biological treatment processes

in a wastewater treatment plant on-site prior to discharge to receiving water at Bandon Estuary (SW1).

Further details of the treatment process are provided in Attachment B. Uncontaminated surface water is

discharged directly to the Brinny River (SW2). Any surface water which does not meet specific limits as

indicated by the monitoring instruments will automatically divert the storm water to a storm water/firewater

retention pond where it may be held and returned to the WWTP for treatment, if necessary. A petrol

interceptor is also connected to the inlet to the firewater retention pond.

Section 2.4.2.3 of the BREF Document gives an overview of the sources of wastewater streams, possible

contaminants and the relevant parameters. As discussed Attachment B the process effluent consists of

effluent from fermentation, purification, formulation, laboratories, cooling towers and boiler blowdown.

D.2.3.3 Waste Generation

The main areas where wastes are produced on site are as follows;

� Production; Wastes are generated in the Fermentation/Recovery and Purification stages of production.

� Laboratory; the main waste generated by the laboratory consist of lab smalls.

� Waste water treatment plant; wastes generated include lime, ammonia and potassium OH.

� Site wide; waste generated by the entire site includes waste electrical goods, cylinders and aerosols,

batteries, printer cartridges, cardboard, plastics, timber pallets, metal and general waste.

Indaver are currently employed on site providing a total waste management service for both hazardous and

non hazardous waste produced on site. As part of this service all waste streams have been identified,

screened and the appropriate method of treatment has been established.

D.2.3.4 Water Consumption

Water is used on site in cooling loops, production of pharmaceutical grade water softening, reverse osmosis,

distillation, steam generation, sanitary and potable use. Water abstraction is metered as are certain uses and

discharge of treated wastewater. Water consumption is approximately 240,000m3 per annum 2009/2010

which has reduced from 258,000m3 in 2007.

D.2.3.5 Energy Use

The energy aspects on site that use significant amounts of energy include fans (HVAC), chillers (HVAC and

process), compressed air (process and instrumentation), boilers, process cooling and process heating. The

electricity consumption of the facility is approximately 35.7 GWh per annum. The site electrical base load is

approximately 58.6 GWh per annum and is relatively consistent over the year. The facility currently imports

both electricity and natural gas.

D.2.4 Control Techniques

The BAT Guidance Note describes the existing or possible measures for eliminating, reducing and controlling

emissions under the following headings;

� Prevention of Environmental Impact

� Minimisation of Environmental Impact

� Management and Treatment of Residues

� Environmental Management

D.2.4.1 Prevention of Environmental Impact

The following preventive techniques as stated in Section 4.3.1 of the BAT Guidance Note are in place at the

facility.

� Integration of Environmental, Health and Safety (EHS) Considerations into Process Development.

Consider EHS issues at an early stage in the process development to identify and prevent,

minimise and design out environmental issues.

An Environmental Management System (EMS) is in place at the facility and the site is accredited to

ISO14001:2004, OHSAS 18001 and IS393 2005. An EHS Specialist is in place at the facility.

� Prevention of Major Accidents and Releases to the Environment. Hazard identification and risk

assessment during process design to determine and implement appropriate control measures to

prevent major accidents and associated releases to the environment.

A detailed emergency response plan is in place at the facility which covers potential accident and emergency

situations and how these are responded to. Also an Environmental Liability Risk Assessment has been

completed for the facility to identify the environmental risks associated with the facility.

D.3 Schering Plough Energy Efficiency Policy

In line with Merck Target 2015 with a goal of 10% reduction of CO2 against 2009 baseline along with Merck

Corporate Policy 24 (Energy) which affirms Merck's commitment to energy conservation and vision to be the

most energy efficient steward in the pharmaceutical industry, Schering Plough (Brinny) endeavours to become

more energy efficient in the way the plant operates day to day.

The site is focused on implementing a range of energy efficiency projects in 2012 and beyond that builds on

previously completed projects through a focused effective energy management approach. Schering Plough

(Brinny) is part of the Large Industrial Energy Network (LIEN) and is also actively engaged with SEAI through

the Energy Agreements Programme.

Many technical audits have been completed to date through both the implementation of IS393/EN16001

Energy Management Standard and through other technology focused or area focused requests.

With the appointment of a full time Energy Lead onsite in 2011, the site plans to facilitate the implementation

of the many recommendations that the audit reports completed to date highlight. Areas of focus include HVAC

optimisation, Refrigeration, Steam usage and water reduction. An energy Community of Practice team is being

set up that will further enhance the achievement of the site's goal in reducing its energy consumption by 10%

against 2011 baseline.
