Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 759
Title: Clean Up and Investigate further two contaminated areas
Start date: 01 Nov 2012
 
Licence Condition
Background There are two plumes of hydrocarbon contamination under the former power station. The first is a historic leak from the fuel lines under the plant which has resulted in free phase hydocarbon on top of the groundwater. The second is a smaller area of contamination in the vicinity of the underground fuel tanks. Deliverables The aim of the PRP is to remove the accessible phase separated hydrocarbon fuel contamination from the groundwater and to determine the full nature and extend of the soil and groundwater contamination from the historic fuel line leak and the more recent petroleum contamination incident in the vicinity of the underground petroleum storage system. The Licensee must implement a program to:         1) Remove accessable phase separated hydrocarbon fuel contamination from the groundwater. This program must commence no later than 1 July 2013.         2) Monitor and investigate the groundwater plume movement to verify if offsite migration of the contamination is or is not occuring. Except as may be expressly provided in any other condition of this licence, or by way of an exemption, the licensee must comply with the Protection of the Environment Operations (Undergroud Petroleum Storage Systems) Regulations 2008 (UPSS Regulation). All works and sampling methodologies in connected with fulfiling this PRP must be undertaken in accordance with all relevant Guidelines made or approved by the EPA under Section 105 of the Contaminated Land Management Act 1997 (CLM Act). By 31 August 2013 the Licensee must submit a written report to the EPA containing the results of the investigation and monitoring in accordance with the NSW EPA (1997) Guidelines for Consultants reporting on Contaminated Sites and other relevant guidelines made or approved by or under section 105 of the CLM Act. If the results from the investigation indicate that the site poses unacceptable risks to human health or the environment - on site or off site - and under either the present or any proposed land use, then a Remediation Action Plan must be prepared to address such risks. It is the intention of the EPA to issue a subsequent PRP if it is determined that further remedial works are required. By 31 August 2014 the licensee must supply a report to the EPA detailing the results of the program for removal of the phase separated hydrocarbons. This report must detail the amount of free hydrocarbons removed from the groundwater and removed from the site for reuse or disposal. The report must also detail the depth of the phase liquid hydrocarbons remaining on the top of the groundwater as at 30 June 2014 and detail the necessity to continue pumping to remove phase separated hydrocarbons along with an anticipated date when such pumping will no longer be necessary.
