The accepted Hunter Valley Access Undertaking requires ARTC to submit documentation to the ACCC for the purposes of an annual compliance assessment. Section 4.10 and Schedule G of the undertaking requires the ACCC to determine whether ARTC has complied with the financial model and pricing principles specified in the undertaking and whether there has been any under or over recovery of revenue from users that needs to be reconciled.
In May 2014, ARTC submitted its annual compliance documentation for the twelve month period from 1 January 2013 to 31 December 2013. The ACCC then issued a consultation paper calling for submissions from interested parties in June 2014. In November 2014, the ACCC issued a position paper setting out its preliminary views on ARTC's compliance for 2013. The ACCC released a draft determination on ARTC’s annual compliance submission for the 2013 calendar year in October 2015.
ARTC submitted revised annual compliance documentation for the 2013 calendar year on 1 April 2016, and the ACCC released its final determination on 6 June 2016.
