explicitly excludes disposal. Transporter shall accept excess water for handling only when Shipper has made the necessary arrangements for disposal of such excess water. Shipper may dispose of its excess water by method acceptable to Transporter such as barging or trucking subject to a mutually agreed upon schedule for excess water removal by Shipper from Transporter's Grand Isle tankage. As an alternative, Shipper may request Transporter to dispose of Shipper's excess water by use of Transporter's onshore disposal wells. The fees for disposal are set forth in Exhibit A. In any event, Shipper must contact Transporter in advance at 713-351-3000 to schedule means by which BS&W will be disposed. Where no meter tickets are available or meter tickets are in Transporter's opinion unreliable, water, sediment and other impurities in the system in excess of that reported on acceptable meter tickets will be allocated in a fair and equitable manner by Transporter. Notwithstanding the fact that Transporter levies a handling charge covering excess water, sediment and other impurities content in a Crude Petroleum stream, Transporter reserves the right to reject any nomination of products other than Crude Petroleum which satisfies all quality standards, requirements and conditions set forth herein. ARTICLE 5 OFFSHORE PLATFORM FACILITIES AND OPERATING PROCEDURES 5.1 Transporter or its authorized representative shall have access to the platform from which shipments are received for the purpose of examining and checking meters and other installations utilized in connection with the handling of Crude Petroleum injected into the pipeline. 5.2 Shipper, upon request by Transporter, shall install, maintain and operate, or make arrangements with platform owners to install, maintain, and operate equipment to inject corrosion inhibitors, biocides, scale inhibitors, paraffin chemicals, or other chemicals as specified by Transporter. 5.3 Shipper shall provide or arrange with platform operator to furnish, operate, and maintain such pumping equipment as is necessary to inject the Crude Petroleum nominated by Shipper for shipment or will cause same to be done. Pumping equipment shall be controlled and operated so that the hourly rate at which Crude Petroleum is injected during each month shall not exceed 120% of the average hourly volume nominated and accepted for shipment during the current calendar month. If piston pumps are used, surge absorbers shall be installed, upon reasonable request of Transporter, to minimize pulsation. Transporter reserves the right, upon written notification to all Shippers to further limit the variation of Shipper's injection rates, if in Transporter's judgment proration is imminent. Reasonable exceptions to variations of injection rates for Shippers with newly discovered, expended production, and unusual production difficulties will be allowed by Transporter. 6 5.4 Physical and legal transfer of custody of Crude Petroleum to Transporter shall be at points where producer's or other delivering parties' lines are connected to Transporter's existing facilities, however, measurement of quantities received for the account of Shipper at such points shall be determined by measurement facilities installed on the production platforms where the Crude Petroleum is produced or to which it is moved for delivery into Transporter's existing facility. 5.5 The Transporter shall have the right to require uniform measurement and sampling equipment/procedures at all installations so that custody transfer measurements are made on a uniform basis. Transporter reserves the right to require Shipper to install or cause platform owners to install in accordance with applicable API and ASTM (American Society for Testing Materials) standards metering and meter proving equipment capable of continuous custody measurement, and devices for continuous proportional to-flow sampling of the Crude Petroleum. 5.6 If Crude Petroleum to be delivered to Transporter is produced at some distance from the Transporter's facilities and Transporter does not elect to provide a connection directly to the production platform where it is produced, Shipper may furnish, or cause to be furnished, free of cost to Transporter, the connecting pipeline required to deliver such Shipper's Crude Petroleum to the location designated by Transporter. If such location is on another producer's platform, all arrangement for installing the connecting pipeline or other required equipment or facilities on such platform shall be the sole responsibility of the Shipper. 5.7 At Transporter's request, Shipper will allow, or cause the platform owner(s) to allow, Transporter to place, operate, repair and maintain riser piping, scraper traps, valves, surveillance equipment, and any other equipment deemed by Transporter to be needed for the safe and efficient operation of the Gathering System. In the event Transporter should decide to transmit meter readings or other data from the platform from which Shipper's Crude Petroleum is run, Shipper will allow,
