Measurement Equipment and Procedures. 8.1 All Gas measurements required hereunder shall be made with equipment of standard make to be furnished, installed, operated, and maintained by MarkWest in accordance with the recommendations contained in ANSI/API 2530 as then published. Producer, or others having Producer’s consent, may, at its option and expense, install and operate check measuring equipment upstream of the measuring equipment to check the measuring equipment, provided the installation of the check measuring equipment in no way interferes with the operation of the measuring equipment. 8.2 All Gas volume measurements shall be based on an assumed atmospheric pressure of 14.4 psia, regardless of actual atmospheric pressure at which the Gas is measured. The factors used in computing Gas volumes from orifice meter measurements shall be the latest factors published by the AGA. These factors shall include: a. Basic orifice factor. b. Pressure base factor based on a pressure base of 14.73 psia. c. Temperature base factor based on a temperature base of sixty degrees Fahrenheit (60°F). d. Flowing temperature factor, based on the flowing temperature as measured by an industry accepted recording device, if, at MarkWest’s option, a recording device has been installed, otherwise the temperature shall be assumed to be sixty degrees Fahrenheit (60°F). e. Super compressibility factor, obtained from the latest AGA Manual for the Determination of Super Compressibility Factors for Natural Gas (AGA 8). f. Specific gravity factor, based on the specific gravity of the Gas as determined under the provisions set forth below. 8.3 MarkWest shall test the accuracy of its measuring equipment at least once every calendar quarter. Additional test(s) shall be promptly performed upon notification by either Party to the other. If any additional test requested by Producer indicates that no inaccuracy of more than two percent (2%) exists, at a recording rate corresponding to the average rate of flow for the period since the last preceding test, then Producer shall reimburse MarkWest for all its direct costs in connection with that additional test within fifteen (15) days following receipt of a detailed invoice and supporting documentation setting forth those costs. 8.4 If, upon test, any measuring equipment is found to be in error by an amount not exceeding two percent (2%), at a recording rate corresponding to the average rate of flow for the period since the last preceding test, previous recordings of that equipment shall be considered correct in computing deliveries hereunder. If the measuring equipment shall be found to be in error by an amount exceeding two percent (2%), at a recording rate corresponding to the average rate of flow for the period since the last preceding test, then any preceding recordings of that equipment since the last preceding test shall be corrected to zero error for any period which is known definitely or agreed upon. If the period is not known definitely or agreed upon, the correction shall be for a period extending back one-half of the time elapsed since the last test. In the event a correction is required for previous deliveries, the volumes delivered shall be calculated by the first of the following methods which is feasible: (i) by using the registration of any check meter or meters if installed and accurately registering; or (ii) by correcting the error if the percentage of error is ascertainable by calibration, test, or mathematical calculations; or (iii) by estimating the quantity of delivery by deliveries during periods of similar conditions when the meter was registering accurately. 8.5 The composition and Gross Heating Value of any Gas stream required to be measured shall be determined by MarkWest at least once each calendar quarter, or more often if deemed necessary by MarkWest, by spot samples, or by using a proportionate to flow sampler located at the point where the measurement equipment is located, by chromatographic analysis, or by some other method mutually acceptable to the Parties. Should Producer request more frequent determinations, the cost of those determinations will be paid by Producer. 8.6 Each Party, at its sole risk and liability, shall have access at all reasonable hours to all facilities which are related to Gas measurement and sampling. Each Party, at its sole risk and liability, shall have the right to be present for any installing, reading, cleaning, changing, repairing, testing, calibrating and/or adjusting of either Party’s measuring equipment. The Parties shall cooperate in obtaining and providing telemetry and similar equipment and systems to provide measurement information to the Parties.
