Updated impact assessment of discharges on the marine environment

05.12.16 i Executive Summary

  1. Two existing sources of effluent, each containing water and IBA leachate, discharge via a single, licensed, outfall to the sea i.e. Pad run-off and NTL quarry dewatering.

1.1 The impact of these was each subject to prior impact assessments that were based on anticipated flow and quality.

1.2 Sufficient actual flow and quality data have now accumulated to show that flows are higher than anticipated whilst strength is in general lower than anticipated. Since the original assessments there have also been some changes to Environmental Quality Standards (EQS) for some of the heavy metals in the leachate. Therefore, re- assessment of the impact assessment, based on real data and current EQS, is needed.

  1. At the same time, a third source of IBA leachate – from the OTL cells – now needs to be managed, and the most appropriate option may be to discharge it via the same outfall.
    Therefore this has been included in the updated assessment.

  2. The combined impact of the three discharges has been calculated for both the averaged flows for each source and for the instantaneous peak flows i.e. at the times when discharge pumps are operating. The values used for averaged and peak flows are as follows:

NTL Q1 Pad run-off Q2 OTL Cells Q3 Total Average (m3/d) 159 100 17.3 276.3 Instantaneous (l/s) 30 7.5 2.4 39.9

  1. It is necessary to define a ‘mixing zone’ within which the discharge is diluted with the seawater by marine currents and wave action, and where strength may exceed EQS. A range of mixing zone sizes has been examined, all lying within guidance criteria published by SEPA.

Two criteria for acceptability have been considered:

i. A minimum dilution of 200x in the mixing zone. This is based on toxicity tests carried out on IBA leachate.

ii. UK regulatory guidance criteria that require the increment in concentration, after dilution, to be ≤10% of EQS.

  1. At averaged flows, with the most cautious (smallest) mixing zone, and maximum source concentrations, all three sources undergo dilution ranging from 2,700x to ~25,000x i.e. far greater than the 200x criterion. The maximum increment in seawater concentration for any element, at these dilutions is 1.4% of EQS. For most metals, the increment is ≤0.1% EQS. At more realistic mixing zone dimensions the dilution is even greater and the impact smaller, therefore comfortably within criteria.

Updated impact assessment of discharges on the marine environment

05.12.16 ii 6. At peak (instantaneous) flows during pumping, using the smallest mixing zone and maximum source concentrations, the dilution factors range from 167x (NTL quarry) to 2,083x (OTL cells), so NTL quarry is borderline with reference to the 200x criterion.
However, its strength is more dilute than the IBA leachate used for the toxicity testing, so the 200x is probably overly protective.

  1. With reference to the EQS criteria, instantaneous peak flows, using the smallest mixing zone and maximum leachate concentrations lead to two metals, copper and chromium, exceeding the “10% EQS” criterion: the increments are 17.2% of EQS (Copper) and 12.1% of EQS (Chromium).

  2. However, this has a very low probability of representing the actual impact. Using more realistic mixing zone dimensions and more realistic source concentrations, even the instantaneous flows cause a maximum increment of only 4.1% of EQS.

  3. It is concluded that the existing and potential discharges receive well above the toxicity- based dilution requirement. It is also concluded that the impact on marine water chemical quality lies well inside the UK criteria for compliance with the Water Framework Directive.

  4. Recommendations are made that will increase confidence in the data used for this assessment and that will reduce the potential impact of the discharges.

The following actions are recommended:

 Check and confirm a reliable value for the Pad pump discharge rate.

 Check and confirm the area of the Pad and whether any run-on from adjacent land areas may be contributing.

 Carry out inter-laboratory cross checks on marine samples and a search for other marine quality data for the Isle of Man.

 Consider capping the OTL cells to reduce leachate generation and/or removal of the IBA and placement into NTL quarry.

 Accelerate the infilling of low areas of NTL so that the sump level can be raised. This should reduce the leachate volumes sooner; then consider changing to a smaller pump, operating for longer periods.

Updated impact assessment of discharges on the marine environment

05.12.16 1 1. Introduction

Assessments of impact on the marine environment have previously been undertaken for:

(i) Sub-surface discharge of migrating groundwater from NTL landfill, contaminated by leachate from matured IBA, together with pumped flows from de-watering NTL quarry during the infilling period.1

(ii) Pumped discharge of collected run-off from the IBA maturation pad.2

Both pumped discharges enter the marine environment via a single discharge point located approximately 50m beyond the mean low water mark. The pipeline route and location of the outfall are shown in Plate 1. The discharge is licensed (Licence no WPA/07/2008).

Plate 1. Route of discharge pipe and location of outfall

Both of the earlier assessments were based on predictions of what the flow and quality of the pumped discharges would be. Since then, flow metering data and chemical analyses of the actual discharges have been obtained and these have shown some differences compared with the predictions. In addition, it appears likely that some leachate from the OTL landfill cells is escaping to the surface, and finding its way into surface water drainage systems. The April 2016 leachate review recommended that the impact of abstracting and discharging this leachate to sea in a controlled manner be investigated.

1 Waste Disposal Licence application: Fate and impact of the attenuated leachate in the marine environment’ Consultancy report for Colas (IoM) Ltd, 11th October 2007. 2 ) ‘Impact assessment for marine disposal of run-off from pad’ Consultancy report for Colas (IoM) Ltd, 17th September 2010.

Updated impact assessment of discharges on the marine environment

05.12.16 2 A further development in the years since the original assessments is that some Environmental Quality Standards (EQS) have been changed in the UK, in order to comply with the Water Framework Directive, 2000/60/EC. Although the Isle of Man is not formally bound by EU legislation, these UK-derived EQS values have been used as a benchmark for assessing the impact of the discharge.

Therefore, it is appropriate to update the risk assessment, based on current data, current standards, and updated predictions of all the sources that are, or may be, discharged via the licensed outfall.

  1. Conceptual model

The conceptual model is shown in Figure 1. Three sources are characterized by a flow rate and chemical composition. They discharge via a single outfall and are diluted in the marine environment by wave action and inshore currents, in a zone around the outfall. This is referred to as the ‘mixing zone’.
After dilution in the mixing zone, the resulting concentrations are compared with EQS values for marine waters.

Figure 1. Conceptual model for assessment of Turkeyland discharges

The individual components of the model are discussed below, in the following sections:

 Flow rates  Leachate source quality  Dilution in the mixing zone  Impact on marine water quality

  1. Flow rates

Flows from the NTL quarry sump and the pad run off collection chamber have been metered since the start of 2015. Available data are shown as time series graphs in Figures 2 and
