Gas Supply (Gas Quality Specifications) Act 2009.

The act is organized in 7 Parts. The primary purposes of Part 2 are to ensure that (a) a gas producer can supply gas, that will flow into a PIA pipeline, of a quality that does not comply with the reference specification for the pipeline; and (b) the gas producer cannot do so until the relevant effects of such supply on the capacity, operations and maintenance of the PIA pipelines have been dealt with in a way that neither materially advantages nor materially disadvantages the operators of the pipelines; and (c) users of PIA pipelines are not materially disadvantaged by the way in which those effects are determined and dealt with. A PIA pipeline is a gas transmission pipeline or a part of a gas transmission pipeline declared by the Minister to be a PIA pipeline.
Part 3 provides for the discipline of modifying gas contracts, and Part 4 recognizes compensation avenues for certain gas consumers and operators of gas transmission pipelines and gas storage facilities. Part 5, Rectifying consumer installations, has as primary purpose to provide for (a) a programme for the modification or replacement of certain consumer installations in preparation for the supply of lower heating value gas to consumers through gas distribution systems; and (b) the operation of an account for the receipt of contributions from gas producers for the purposes of funding the programme; and (c) a scheme of reimbursement under which the cost of the programme is apportioned between gas producers who supply lower heating value gas that flows into certain gas transmission pipelines during the reimbursement period.
