Licensed Discharge Points (LDP)

IXOM Port Kembla has three licensed discharge points on its EPA license. Two are for discharges to air (LDP1 and LDP2) and one is for discharge to waters (LDP4). 

IXOM Port Kembla LDP

LDP1: SARP Stack

The SARP stack is the tallest concrete stack at IXOM Port Kembla and is referred to as Licensed Discharge Point 1 (LDP1) on the site's EPA license. This discharge point is no longer used. 

LDP2: SMBS Plant Stack

The SMBS plant stack is the smaller fibreglass white stack to the south west of the SARP stack. This stack is designated as Licensed Discharge Point 2 (LDP2) on the site's EPA license. The stack is continuously monitored for SO2 concentration only and the license specifies a maximum SO2 concentration that can be discharged through it. 

LDP4: Liquid discharge point to council drain adjacent to Tank 7

This licensed discharge point is the only discharge point for treated wastewater from the site and is the final step in a comprehensive wastewater treatment system that the site operates. The discharge point consists of a final batch tank including pH monitoring, control system, agitator to ensure thorough mixing, pH control system and discharge monitoring equipment. All treated wastewater entering the system is checked for pH prior to discharge and all liquid discharged is continuously monitored and trended for pH, total suspended solids and flow. The license conditions for this point include a required pH range (6.5 to 8.5), maximum average TSS limits during discharge for wet and dry weather and total volume discharged per day.

Weather Monitoring

IXOM Port Kembla is required by license to monitor rainfall per 24 hour period in order to determine ‘wet’ and ‘dry’ weather conditions as part of the TSS discharge license. To meet this requirement the site has installed an automatic weather station (AWS) to allow continuous monitoring, recording and trending of weather conditions 24hrs per day, 7 days per week. The instrument installed not only allows recording of 24hr rainfall as required by the EPA license but in addition records other weather measurements including wind speed and direction, temperature, relative humidity, rainfall intensity, barometric pressure and other information. 

Pollution Notification

Comprehensive emergency response plans (ERP) have been developed for IXOM Port Kembla to limit the consequences and assist in managing an emergency situation which may develop at the site and have the potential to impact either onsite or offsite personnel, property or environment.

The likelihood of a pollution incident that could affect the community from the activities of the site is very unlikely so the risk is low.
