Introduction 1.0

This report has been prepared in response to notification on Licence: W0113-04 - KMK Metals Recycling Limited, which was submitted on the EPA’s EDEN site on 07/12/2018.

(Licensee Submission LR035220 RE: EDEN Reference Numbers RI008488, RI008489 & SV15407)

The notification states the following:

• The EQS values from the Environmental Objectives (Surface Water) Regulations 2009 are listed incorrectly for the following parameters; Nickel, Mercury, Copper, Lead and Chromium.

• Table 3.1 lists the Ammonia as N proposed warning and action trigger level as 1.603 & 2.071 respectively. A discharge of this level would not be considered representative of rainwater from roof and non-process area.

• The action trigger levels for both Zinc and Lead are above the EQS value from the Environmental Objectives (Surface Water) Regulations 2009.

• Regarding the pH parameter values, both a lower and upper range warning and action trigger level should be determined.

In addition, the warning and action trigger levels have been updated to take account of data available to November 2018.

Methodology for Setting of Trigger Values 2.0

The setting of trigger level values was carried out in accordance with the EPA document “Guidance on the setting of trigger values of storm water discharges to off-site surface waters at EPA IPPC and Waste Licensed Facilities”, Rev 1 dated 07/09/12. The guidance document states that the status of and possible impacts on receiving waters from storm water emissions must be considered, bearing in mind that the Water Framework Directive (WFD) requires no deterioration in the status of a water body.

As per the EPA guidance on the setting of trigger level values for storm water discharges, the calculations of the proposed trigger level values for the site involved the analysis of data from multiple sampling occasions at each of the storm water discharge points at KMK Metals Recycling Ltd. During this evaluation process, any storm water samples identified as likely to have been contaminated by on-site processes were not included when calculating the average and standard deviation values as this would not give an accurate reflection of ‘normal’ values, resulting in the setting of trigger level values which are too high. In accordance with the EPA guidance, averages and standard deviations were calculated for each parameter using monitoring data that excluded any of the outliers mentioned previously.

For trigger warning limit values, the average result plus 2 standard deviations was used to determine the trigger value and for trigger action limit values the average result plus 3 standard deviations was used to determine the trigger value.

The surface water emission quality results were compared to the European Communities Environmental Objectives (Surface Waters) Regulations 2012 and 2009 Environmental Quality Standards (EQS), SI 327 of 2012 and S.I No.272 of 2009 where available; and the proposed calculated trigger level values.

EQS values are reported as either Maximum Allowable Concentration (MAC) or Annual Average (AA). Where available, the MAC was used. If the MAC was not available, the lower value of the Annual Average criteria was used.

2.1 Proposed Trigger Warning and Action Values Water quality analysis data for the DX storm water discharge point is available from the third quarter of 2015 to November 2018. Water quality analysis data for the E storm water discharge point is available from the first quarter of 2014 to November 2018.

Proposed trigger warning and action values have been calculated for pH, using the methodology above.

The water quality results are presented in Appendix 1. The resulting proposed warning and action trigger values for storm water discharges DX and E are presented in Table 2-1 and Table 2-2 below.

2.2 Updated EQS Values The EQS values have been updated to include the correction of the EQS for Nickel, Mercury, Copper, Lead and Chromium.

An EQS for ammonia as N has been included as 0.065mg/l, which is the SI 272 of 2009 value for Good Status for ammonical nitrogen as N.

Where possible, the dataset for the proposed action value has been amended by removing higher values to reduce the value to below the EQS.

However, where ongoing exceedences of the EQS have been noted, the updated EQS values remain lower than the action warning values for some parameters. This is the case for ammonia and copper, and a note has been made in Table 2-1 and Table 2-2.
