YOUNG GAS STORAGE COMPANY, LTD.

ANNUAL AVERAGE THERMAL CONTENT OF GAS IN STORAGE POSTING

FOR 2019 - 2020 SEASON

General Terms and Conditions (“GT&C”) Section 1.2 of the Young Gas Storage Company, Ltd. (“Young”) FERC Gas Tariff, First Revised Volume No. 1 (“Tariff”), states that Young shall monitor storage injections and withdrawals and calculate the actual Young  Average Thermal Content (“ATC”) of gas in storage field on October 31 of each year. If the actual Young ATC deviates from the currently effective Young ATC (1099) by more than plus or minus 20 Btu per cubic foot (“Btu”), the actual Young ATC will become the new effective Young ATC and it shall be posted on Young's electronic bulletin board under Information Postings by November 15 of each year, and a corresponding adjustment will be made to Shipper's applicable Maximum Daily Injection Quantity ("MDIQ"), Maximum Daily Withdrawal ("MDWQ") and Maximum Available Capacity ("MAC") entitlements.  

Based on a review of storage field gas monitoring data, Young has determined that the ATC has changed by more than 20 Btu's from the currently effective ATC.  Therefore, the updated ATC of 1124 Btu shall become the new effective ATC as of December 1, 2019.  Accordingly, a revision to the currently effective Young ATC and the related storage entitlements and service rates is necessary.

Based on these ATC related changes, Young is updating the related entitlements and rates as described below.
