1 EXECUTIVE SUMMARY AND INTRODUCTION TO THE 2018 AER

This Annual Environmental Report has been prepared for D0033-01, Cork City, in Cork in accordance with the requirements of the wastewater discharge licence for the agglomeration. Specified reports are included as an appendix to the AER as follows:

1.1 Licence specific reporting included in AER

Assessment / Report Included in AER

There is no Licence Specific Reports included in the AER.

1.2 Treatment Type

The agglomeration is served by a wastewater treatment plant Carrigrennan (Cork City) WWTP with a Plant Capacity PE of 413200. The treatment process includes the following:

1.2.1 Carrigrennan (Cork City) WWTP

Yes / Treatment type Details No

Screening (5mm) & de-gritting: Local flows only,- flows from City previously screened and de-gritted at Ballinure Header Preliminary Yes Chamber. ; Storm Water Treatment: 4 Tanks (stprage/settlement/return/overflow) ; Pre-Aeration, with odour control treatment Treatment of removed gases

Primary Yes Primary Clarification: 2 settlement tanks, (covered) sedimentation / removal of settable solids Treatment

Secondary Yes Sequencing Batch Reactor, 8 Rectangular Basins Treatment Yes / Treatment type Details No

Nutrient No Removal

Tertiary No Treatment

The overall compliance of the final effluent with the Emission Limit Values (ELVs) is shown below. More detailed information on the below ELV’s can be found in Section 2.2 Discharges from the agglomeration.

1.3 ELV Overview

1.3.1 Carrigrennan (Cork City) WWTP

Compliance Status

Were all parameters compliant for Carrigrennan (Cork City) WWTP treatment plant No

Where noncompliant see table 2.2.1 for details of parameters

1.4 Sludge Removal

The amount of sludge removed from the wastewater treatment plant is shown below along with the transported destination of the sludge from the treatment plant.

Treatment Plant Sludge type Quantity Unit % Dry Solids Destination

Carrigrennan (Cork City) WWTP Dried Sludge 3031.74 Weight (Tonnes) 92 Local Agricultural Landspreading

Carrigrennan (Cork City) WWTP Cake Sludge 199.42 Weight (Tonnes) 19 Local Agricultural Landspreading

Annual Statement of Measures No Significant works nor changes were undertaken in 2018 2 MONITORING REPORTS SUMMARY

2.1 Summary report on monthly influent monitoring

A summary of influent monitoring for the treatment plant is presented in below. This monitoring is primarily undertaken in order to determine the overall efficiency of the plant in removing pollutants from the raw wastewater.

2.1.1 Influent Monitoring Summary - Carrigrennan (Cork City) WWTP

Parameters Number of Samples Annual Max Annual Mean

BOD, 5 days with Inhibition (Carbonaceous BOD) mg/l 261 300 120.46

Total Phosphorus (as P) mg/l 30 4.7 2.41

COD-Cr mg/l 261 1100 333.32

Suspended Solids mg/l 261 420 167.03

Total Nitrogen mg/l 30 34 16.99

Hydraulic Capacity 0 282460 120565

If other inputs in the form of sludge / leachate are added to the WWTP then these are included in Section 3.5 if applicable Significance of Results: The annual mean hydraulic loading is less than the peak Treatment Plant Capacity as detailed further in Section 3.2. The annual maximum hydraulic loading is less than the peak Treatment Plant Capacity as detailed further in Section 3.2. The design of the wastewater tretament plant allows for peak values and therefore the peak loads have not impacted on compliance with Emission Limit Values.

Notes: 1– This represents the Emission Limit Values after the Interpretation provided for under Condition 2 of the licence is applied 2 - For parameters where a mean ELV applies Cause of Exceedance(s): Nutrient removal does not form part of the WwTP process Significance of Results: The WWTP is non-compliant with the ELV’s set in the Wastewater Discharge Licence for Total N and Total P.

2.3 Ambient monitoring summary

A summary of monitoring from ambient monitoring points associated with the wastewater discharge is provided in the sections below. For discharges to rivers upstream (U/S) and downstream (D/S) location data is provided. For other ambient points in lakes, coastal or transitional waters, monitoring data from the most appropriate monitoring station is selected.

2.3.1 Ambient Monitoring Report Summary - Carrigrennan (Cork City) WWTP

The table below provides details of ambient monitoring locations and details of any designations as sensitive areas.

2.3.2 Ambient Monitoring Parameter Summary - Carrigrennan (Cork City) WWTP

The results for ambient results and / or additional monitoring data sets are included in the Appendix 7.1 - Ambient monitoring summary Significance of Results: The WWTP discharge was not compliant with the ELV’s set in the wastewater discharge licence. The ambient monitoring results did not meet the required EQS. The parameters which exceeded the EQS and may be causing an are: None. The discharge from the wastewater treatment plant do not have an observable impact on the water quality. The discharge from the wastewater treatment plant do not have an observable negative impact on the Water Framework Directive status.

3 OPERATIONAL REPORTS SUMMARY

3.1 Treatment Efficiency Report

Treatment efficiency is based on the removal of key pollutants from the influent wastewater by the treatment plant. In essence the calculation is based on the balance of load coming into the plant versus the load leaving the plant. The efficiency is presented as a percentage removal rate. A summary presentation of the efficiency of the treatment process including information for all the parameters specified in the licence is included below:
