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, or cause the platform owner(s) to allow, reasonable access to and use of communication facilities which may be available at the platform. 5.8 Where meter readings are available Transporter will prepare, as near as practicable to 7:00 a.m. on the first day of each month, a monthly pipeline run ticket for Shipper showing opening and closing meter readings and water, sediment, other impurities percentage on the basis of which Crude Petroleum and water, sediment, and other impurities volumes will be determined. If for any reason Transporter's representative fails to reach any receipt point on the first day of the month, Shipper's own representative, with prior authorization from Transporter, will obtain and make a record for Transporter's representative of the closing meter reading and will withdraw the sample material from the sampling equipment. The sample material thus withdrawn will be sealed in a special container and retained by Shipper's representative for Transporter's representative who will, during his next trip to that receipt point, determine the water, sediment, and other impurities percentage of the sample material in the special container and prepare the monthly pipeline run ticket. Where no meter readings are available, Crude Petroleum including water, sediment and other impurities will be determined by Transporter from the best available data. 7 5.9 It is recognized that from time to time producers inject acid into well formations containing Crude Petroleum in an attempt to stimulate production and fluids subsequently produced from such wells may contain unspent acid which must be neutralized to a pH of 4.5 or greater before the fluids (with which acid is produced) are delivered to Transporter. If such total fluids (Crude Petroleum plus unspent acid) is not so neutralized, the Gathering System may have to be shut down which in turn will require all connected producers to shut in their wells. To assist Transporter to anticipate the need and to prepare for possible corrective actions which may be required to void or minimize operating difficulties caused by any unneutralized acid, Shippers shall furnish, or cause the producer from which Crude Petroleum is purchased to furnish to Transporter, the following information at least 24 hours in advance of start of production from any well which has been acidized: (i) estimated time of first production from acidized well; (ii) estimated time that first production from acidized well, which has been neutralized to a pH equal to or greater than 4.5, will be injected into the Gathering System; and (iii) estimated time that produced fluids from previously acidized wells, which has been neutralized to a pH equal to or greater than 4.5, will be free of neutralized acids. Shipper shall assume full responsibility for and reimburse Transporter for all extra costs and expenses incurred by Transporter as the result of any unspent and/or unneutralized acids being present in the Crude Petroleum delivered to Transporter by Shipper. Shipper will be billed for all such extra costs and expenses for shutting down, purging of such unspent acids, and subsequent resuming operation of the Transporter's Gathering System. Transporter shall not be liable to any Shipper for any damage sustained by Shipper(s) as the result of unspent and/or unneutralized acids being received from other Shipper(s). 5.10 In the event that Shipper does not operate the wells from which the Crude Petroleum nominated for shipment is produced or does not operate the treating, measurement, or pumping equipment through which such Crude Petroleum is handled prior to its delivery to Transporter, then Shipper shall designate the party or parties responsible for the operation of such facilities and shall authorize and direct such party or parties to (1)
