PIPELINE FLUIDS DELIVERY SPECIFICATION
In order to meet this specification, Pipeline Fluids delivered by the User to the Processor for processing under this Agreement shall be commercially free from objectionable odours, radioactivity, materials, dust, sand, or other solid or liquid matter (other than the Associated Liquids specified below), drilling muds, acid ising fluids, fracturing fluids, proppants, foaming agents, excessive dissolved solids, waxes, gums and gum forming constituents which might cause injury or interference with the proper operation of the TGPP and/or the TGPP Liquid Pipelines or which could be expected to remain in Natural Gas and interfere with the proper operation of the lines, meters, regulators or other appliances through which it flows.
