(3) How thick is the tarpaulin.

(4) Can the Minister provide a copy of the (a) operating procedures for use of the tarpaulin, (b) plans for, and results of, the trial of the use of the tarpaulin and (c) documentation for application, and approval of the change to the Environmental Authorisation relating to the change from using soil for capping to tarpaulin.

(5) How many complaints have been made regarding the tip smell since the beginning of 2016.

(6) Can the Minister provide a breakdown, by how many complaints each year in this period (as outlined in the Environmental Authorisation), including those passed on from the Environment Protection Authority to the Authorisation holder.

(7) Can the Minister provide a copy of the (a) guidelines and any documentation for the system to deal with odour complaints and other odour-related issues and (b) program and results of field odour surveys around the site boundary.

(8) Can the Minister provide the annual report (as required by the Environmental Protection Authority) for (a) Remondis (EA 0375) and (b) ACT NoWaste (EA 0402), for the years to end of June (i) 2015, (ii) 2016, (iii) 2017, (iv) 2018 and (v) 2019.

Mr Gentleman: The answer to the member’s question is as follows:

(1) On 16 July 2019, the Environment Protection Authority (EPA) approved a 12 month trial on covering the tip face with tarpaulins, an alternate day cover to soil. The trial is for the period 1 September 2019 to 1 September 2020. Remondis starting using the Tarpomatic system on 3 September 2019.

(2) Remondis Australia requested the use of a tarpaulin cover technology (Tarpomatic system) instead of soil, as day cover, a requirement under their contract with ACT NoWaste for the operation of the Mugga Lane landfill. An essential part of landfilling operations is the placement of cover over wastes. The purpose of daily cover is to:

minimise landfill odours

control litter

prevent the spread of fire

control disease vectors such as birds, flies, mosquitoes and rodents

ensure that the landfill is trafficable

Traditionally daily cover has been in the form of soil. Materials other than soil, such as foams, mulch, papier-mâché, gravel or cover mats, may also achieve these purposes and may meet other operational needs. However, alternate cover materials to soil should only be used when an assessment of their appropriateness for use at that specific landfill has been undertaken by the landfill operator and the use of those materials approved by the EPA. This is the purpose of the trial, notwithstanding tarpaulin cover technology is widely used throughout landfill sites both nationally and internationally.

(3) The Tarpomatic system being trialled by Remondis is approximately 0.60 mm thick based on a weight of 340 grams per square metre (gsm) and is classified as a super
