Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 1802
Title: Pollution Reduction Program 8 - Investigations and Upgrades to the Sewerage Reticulation within the Terrigal Lagoon Catchment
Start date: 17 Sep 2021
 
Licence Condition
Background and purpose of the Pollution Reduction Program Investigations by the University of Technology Sydney of the major lagoon systems of the Central Coast indicate that the Terrigal Lagoon has increased bacteriological contamination, principally of human origin, especially during or immediately after prolonged rainfall events.   The purpose of this Pollution Reduction Program is for the licensee to: investigate all potential sources of sewage contamination in Terrigal Lagoon catchment from the sewerage reticulation system and connections to this system; prioritise actions for addressing all potential sources of sewage contamination in the Terrigal Lagoon catchment; and implement a program of works to repair or replace those parts of the sewerage reticulation system that pose a risk to human health and the water quality of Terrigal Lagoon and surrounds.
Deliverables The Audit The licensee must complete an audit pertaining to the sewerage and stormwater reticulation systems relating to water quality issues within Terrigal Lagoon and develop actions and works proposed to address those issues ('the Audit'). The licensee must complete investigations into the areas identified within the Audit as 'High Risk Infrastructure' (*) that needs repairs/upgrade works; what those repairs/upgrade works should be; and determine timelines for the completion of each of the identified works. (*) 'High Risk Infrastructure' means: Sewer mains located above, or adjacent to, or crossing, stormwater drains or culverts; Sewerage network consisting of aged and/or more vulnerable pipe materials, located in close proximity to the stormwater network, watercourses or natural waterways; Sewerage network with a history of failure in proximity to the stormwater network, watercourses or natural waterways; Designed overflow points from the sewerage network.The Audit must include a list of scheduled works proposed to be undertaken to repair, replace or upgrade those parts of the sewerage reticulation system identified as needing attention, actions that may be necessary that are not works; and timelines for the completion of each of the identified actions and works. The licensee must utilise its environmental health expertise in setting timelines for actions and works based on any public health risks identified. By 30 September 2022 the licensee must provide the EPA with a report identifying the actions, works and timelines as identified through the Audit.  This report must be supplied to the EPA at RegOps.MetroRegulation@epa.nsw.gov.au   Works and Actions By 31 December 2023 the licensee must complete the actions and upgrade works identified in the Audit Report to address the potential contamination issues identified in the Terrigal Lagoon and surrounds and supply a report to the EPA (at RegOps.MetroRegulation@epa.nsw.gov.au ) that identifies all actions and works completed as part of this condition. Note: Following the completion of the Terrigal Lagoon catchment investigations and works, it is the intention of the EPA to require similar investigations in other catchments, including Avoca Lagoon.
