INTRODUCTION
Project Management Group (PM) has been commissioned by Swords
Laboratories t/a Bristol Myers Squibb Cruiserath (BMS) to carry out an
assessment of the potential effect on ambient air quality of increasing air
emission limits for nitrogen dioxide (NO2).
BMS was granted an IPC licence by the Environmental Protection Agency which
came into effect on 27th October 2000, upon commencement of commercial
manufacture on-site. As part of the original IPC application air emission
modelling was carried out by Enterprise Ireland to determine the effect of facility
operation on ambient air quality. The results indicated that concentrations of
modelled pollutants would remain below the relevant air quality standards (see
Appendix 12.C4 of IPC Licence Application, Register No. P0552-01, for full
report).
Air dispersion modelling has been undertaken to determine the effect of an
increase in the NO2 emission limit on ground level concentrations (GLCs) of
NO2.

Modelling Approach

Dispersion modelling has been carried out using the AERMOD computer model
developed by the US EPA. The model consists of mathematical algorithms which
simulate the transport and dispersion of air pollutant emissions downwind of a
source. AERMOD is a steady-state plume model which represents the plume as
having a normal (Gaussian) distribution in both the horizontal and vertical
directions for the stable boundary layer (SBL) and the horizontal direction for the
central boundary layer (CBL), but a bi-Gaussian probability density function for
vertical distribution in the CBL.
The model predicts average concentrations over 1-hour, 8-hour, 24-hour and
annual periods and percentiles thereof. The model allows for the effects of
general plume rise, stack tip downwash and building downwash.
AERMOD is increasingly used in Ireland for the assessment of air quality impact
and has previously been accepted by the Irish EPA for such assessments.

Air Quality Standards for the protection of human health and the environment
have been developed at European level and incorporated into Irish legislation.
Air Quality Standards (AQSs) set limit values for Ground Level Concentrations
(GLCs) of certain emissions for both short-term (e.g. hourly, daily) and long-term
(e.g. annual) averages. Limit values are often expressed as percentiles e.g. 98
percentile of an hourly average value which means that only 2% of the results
obtained during the monitoring period can exceed the stated hourly average limit
value.
ns
en
The AQSs which apply in Ireland are contained within the following legislation:
The Air Pollution Act, 1987 (Air Quality Standards) Regulations, 1987 (S.I.
No. 244 of 1987)
•
Air Quality Standards Regulations, 2002 (S.I. No. 271 of 2002) relating to
the limit values for sulphur dioxide, nitrogen dioxide and oxides of nitrogen,
particulate matter, lead and carbon monoxide in ambient air.
Co
•
The various AQS limit values and guidelines are summarised in Table 1.1. These
standards have been used in the current assessment to determine the potential
impact of the proposed development on air quality.

Meteorological Data
The meteorological data required by the dispersion model is wind speed, wind
direction, Pasquill-Gifford stability category, boundary layer height and ambient
temperature. The stability category and boundary layer height are used to
characterise the turbulence within, and the height of the lower levels of the
atmosphere.
Extremely unstable conditions can cause plume looping and elevated
concentrations close to the stack. Under stable conditions elevated
concentrations can occur due to the emissions being trapped below the
boundary layer. Neutral conditions, characterised by cloudy skies and strong
winds, are most favourable for dispersion due to the mechanical mixing of the
lower atmosphere. The wind direction determines the direction in which the
plume is blown, and for a particular stability, higher wind speeds will result in
reduced plume rise so causing the plume to reach ground level closer to the
stack with elevated emission concentrations. The boundary layer height
determines the total vertical distance over which the plume may spread.

Air streams blowing across buildings can become disrupted, with turbulent
eddies occurring downwind in the building wake. If an emission point is
sufficiently close to a building, then the plume may become entrained in the
turbulent eddies of the building wake. This entrainment can cause plume
downwash resulting in elevated emission concentrations close to the emission
point. The stacks modelled are subject to downwash and therefore building
dimensions were added to the model.

Co
2.1.4
ns
en
The AERMOD model interprets the influence zone of each building for a given
wind direction using the Building Profile Input Program (BPIP). All of the main
buildings on the site were included in the modelling analysis.
The model was set up to examine the impact of emissions on the area
surrounding the facility using a series of receptors. A receptor is a location at
which the model will calculate maximum GLC. A cartesian co-ordinate receptor
grid system was established with its centre approximately at the location of the
main electrical substation on site.
A 10km square grid was created for initial model runs, to determine the
approximate location of short term maxima. When it was determined that these
fell within 1 km of the site, a more detailed, higher resolution 3 km square grid
was adopted. Receptors were placed at 100 m intervals over the grid, along and
outside the site boundary.

Emission Data
The current facility operations result in NO2 emissions from both the boilers and
incinerator. NO2 emission levels from the boilers vary depending on whether they
are run on natural gas or gas oil. The current BMS Cruiserath IPC Licence (No.
552) limits for emissions of NO2 are listed in Table 3.1.

Meteorological Data
Five years (2001 – 2005 inclusive) of meteorological data were used in the
model. The data was recorded at the meteorology station in Birr, Co. Offaly and
supplemented by cloud cover data for the same periods from the Casement
meteorology station.
The data obtained consists of hourly values of wind speed, wind direction, air
temperature, stability category, mixing height and cloud cover. Wind direction is
converted to a flow vector (the direction toward which the emission moves) by
adjusting the direction by 180 degrees.

MODELLING RESULTS
The model was run for the scenario outlined in Section 3.4 during each year
2001-2005. The resulting GLCs are tabulated in Tables 4.1 & 4.2.
Nitrogen Dioxide (NO2)
The results for Scenario 1 indicate that increasing the emission limit of NO2 from
the incinerator from 100mg/m3 to 200mg/m3 would not lead to an exceedence of
the hourly average air quality standard limits. The 99.8%ile of the hourly average
GLC resulting from the increased emission is only 40% of the hourly average
limit and the maximum predicted annual average GLC is only 8.2% of the limit.
In summary:
Increasing the emission limit of NO2 from the incinerator from 100mg/m3
to 200mg/m3 would not lead to an exceedence of air quality standard
limits.

The maximum emission should be stated for each material emitted, the concentration should be based on the maximum 30 minute mean.
Concentrations should be based on Normal conditions of temperature and pressure, (i.e. 0oC101.3kPa). Wet/dry should be clearly stated. Include reference oxygen conditions for
combustion sources.
Fume hoods are used to handle small volumes of material, usually less than 5 litres at a time. Due to the intermittent and unscheduled nature of these operations and the large
number of compounds that may be handled, it has not be practical to quantify these emissions. Based on BMS experience and best engineering judgement, these emissions will be
very minor.
The drum lids are cracked open during warming. Only small volumes of vapour are produced per drum – averaging < 1litre. Vapours are not extracted so this is a one off emission
per drum.

Potential Emission Points
These are points which need to vent to atmosphere in emergency situations, but remain closed under normal situations. These include reactor and
other process vessel bursting disc vent lines. Reactor bursting disk lines are directed to the disengagement catch tanks to minimise liquid and hence
vapour emissions to atmosphere and surface water. The catch tank is located outside and to the north of the production building. The solvent
recovery plant also has a catch tank which is located at the solvent recovery plant. Tank farm bulk storage tanks also have relief valves, which will lift
only under abnormal situations.
The incineration line has a vent which opens in the event of loss of power or other emergency condition, requiring an immediate shut-down of the
system. It opens to prevent damage to downstream equipment. The vent is not used for start-up or normal shut-down. The back-up cryogenic
condenser unit also has a vent which opens in the event of loss of power or other emergency condition.
The vent from the WWTP will be directed to atmosphere during incinerator shutdown.

Bursting disk: considerable engineering effort is invested in eliminating as far as possible this emission scenario. However, safety is paramount and provision of a bursting
disk and relief valve emergency vent systems meets this requirement. In the event of an emission, the environmental impact is minimised as far as possible by provision of a
catch tank. This disengages up to 90% of liquid entrained in a vapour flow. Figures given in this table are for maximum potential emission and do not allow for the effect of
the catch tank.
