Effective May 1, 2022, this Agreement amends and restates the Amended and Restated Transportation Service Agreement No. 3227, originally effective May 1, 2002, as subsequently amended, restated and/or superseded prior to or as of the effective date hereof; in particular, this Agreement replaces and supersedes that Amended and Restated Transportation Service Agreement executed by MRT on October 12, 2021 which was to become effective as of August 1, 2022. Pursuant to Section 15.8, GT&C of MRT's Tariff, the parties have agreed to an extension of the term with respect to all of the capacity previously committed under this Agreement. Upon providing satisfactory proof of natural gas load reduction directly related to a physical production process change (e.g., electric arc furnace replacing gas fired blast furnace), Customer shall have the right to reduce MDQ by such proven load reduction amount. Any such reduction shall first occur under Customer's FTS Agreement #6112. To the extent the proven reduction amount is not satisfied by the MDQ reduction under FTS Agreement #6112, an MDQ reduction may occur under this Agreement; provided, however that in no event shall Customer's total MDQ under this Agreement #3227 and FTS Agreement #6112 be reduced to an amount lower than 37,766 Dth/D. Any MDQ reduction under this section shall be allocated as follows: Market Zone only capacity of up to 10,832 Dth/D shall be reduced first with the remaining amount of the proven reduction amount 5,168 Dth/D allocated to Field to Market Zone capacity. In order to exercise its reduction rights under this section, Customer shall provide notice of its intent to reduce its MDQ, including full particulars and proof satisfactory to MRT of load reduction by December 31, 2022 to be effective June 1, 2023. Primary Path From: #808527 Waskom - EGT To: #805495 Granite City Steel Line Capacities and Line Priorities applicable to services provided under this Agreement shall be determined pursuant to the provisions of MRT's Tariff (currently set forth at GT&C Section 8.2(b)), as subsequently amended and in effect from time to time. Line Capacity West 4,087 Dth/D On any given day, the customer is entitled to the greater of 4,087 Dth or 4.0% of available West Line capacity. Rate Zone Capacities Field 42,934 Dth/D Market 46,728 Dth/D On any day MRT shall not be obligated to receive or deliver a cumulative quantity in excess of the MDQ set forth in this Agreement.
