EMISSION OF POLLUTION THROUGH SHAFTS FROM FLØ)'.'FJELLSTUNNELEN, BERGEN

1 INTRODUCTION

Hordaland road authorities have asked for an evaluation of the shaft emissions from FlØyfjellstunnelen in Bergen including a recommendation for emission conditions at different sites. The amount of ventilation air and the pollution concentrations to be considered have been specified in ref. 1.

2 METHODS OF EVALUATION

The report refer to wind measurements carried out near different sites in Bergen. Further reference is made to results of one tracer experiment recording the dispersion of SF

6 tracer gas around an existing shaft from "Løvstakktunnelen" in Bergen (2).

Different methods for dispersion calculations have been considered including

a) dispersion from a ground-level source

b) dispersion effect caused by the wake behind the shaft house

c) dispersion from an elevated source.

The results indicate the importance of high emission velocity in order to get an elevated plume.

In the following evaluation formulaes presented in (3) were found most applicable. These formulaes discribe our tracer experiment reasonably well. The methods separate between the stack aerodynamic effect and the momentum phase of dispersion being important for the problem to be considered.

3 EAST TUBE EMISSION

Two alternative emission sites are shown in Figure 3.1, marked alt. 1 and alt. 2. The site for the wind station is marked in the figure. The wind statistics of one year of hourly measurements are given in Appendix 1. The terrain profile of each site is given in Figure 3.2a and b.

3.1 Alternative 1

Due to distance and height of release above the building areas, the influence of pollution in this area will be negligible. This location is preferable to alternative 2.

3.2 Alternative 2

The horizontal distance from the shaft to the living areas is about 75 m and the height difference 30 m. A critical wind sector is marked on the figure. The windfrequencies for each season given in Appendix 1 show that at Sandviken the wind is blowing in the critical sector about 7-10% of the time during daytime (07-19) when emission occur. In summer a very small frequency of wind observa- tion was recorded in the critical sector. On the other hand calm conditions are recorded 10-20% of the time when emission occur.

When the wind is blowing in the critical sector, the wind speed is smaller than 2 m/s and the air mixing is poor.

4 WEST TUBE EMISSION

The emission site is shown in Figure 4.1, further the site of the wind station, and the critical wind sector for the shaft emission are marked on the map. The terrain profile is shown in Figure 4.2.

Figure 4. 2 show that the height differe.nce between the ventilation shaft and Skansemyren building areas is close to 100 m and the

e Z feet of the em Lss Lon wi.11 here be negligible.

The height difference between the ventilation shaft and Fløyen is about 30 m. The wind rose from Skansemyren show that (see Appen- dix 1) the wind is blowing in the critical sector more than 20%

of the time in the afternoon. The distance between the emission shaft and Fløyen is about 75 m.

Comparing the two additive terms in the denominator in equation 4.1 it is seen that the effective emission height is important for the dilution factor.

The dispersion is expected to be smaller than previously calculated when the windspeed u is smaller than

However, when the exit velocity exceeds 10 m/s this is not expected to be a problem. The difference in density will be reduced during the momentum phase of dispersion.

6 CONCLUSIONS

The emission through the shaft from.east tube may effect Fløyen area at 75 m distance in a few afternoon hours about 20% of the days in the summer. If the emission velocity is higher than 10 m/s (stack diameter 6.7 m) and the emission height is 5-10 m, the concentrations are expected to be acceptable (not exceeding standards for outdoor air quality). Due to the height difference and the wind distribution the impact on the building areas near Skansemyren is expected to be negligible.

Two alternat~ves have been given for the location of the shaft from the east tube.

Alternative 1: From an air pollution point of view this location is recommended. Due to the height difference there will be neglig- ible pollution in the building areas. If the emission conditions previously recommended are used, the polluted air will mainly remain

- 12 -

elevated in weak wind situations and the concentration in the close neighbourhood wi.11 also be small.

Alternative 2:

During calm wind conditions polluted ventilation air may drift to- wards the building areas. These conditions are expected to occur during the morning hours a few percent of the days.

The air turbulence (mixing) will be low in these situations.

However, when the emission velocity is above 10 m/s, ground level concentrations is expected to be low in the weak wind situations.
