Gavilon LLC and Tenaska Marketing Ventures, jointly are seeking waivers from FERC to allow completion of a deal selling Gavilon’s wholesale gas marketing business, including transportation and storage contracts, to Tenaska.

The two companies filed Tuesday, requesting expedited action by the Federal Energy Regulatory Commission on temporary waivers of capacity release regulations and policies and related pipeline tariff provisions that would allow the transaction to go forward.

The parties requested a short comment period of seven days and approval by FERC by March 25. The assets to be transferred include firm transportation contracts on ANR Pipeline and Midcontinent Express, and firm storage at Arlington Storage Co., Leaf River Energy Center and Perryville Gas Storage, as well as park and loan space at Leaf River. The contracts would be transferred to Tenaska, which would continue to fulfill the terms of the contracts.

The request was for a 90-day waiver of the Commission’s capacity release regulations and policies, along with the respective tariff provisions of the affected pipelines, and any other authorizations or waivers necessary for the permanent releases of transportation and storage capacity.

Gavilon ranked No. 21 on NGI‘s latest Top North American Gas Marketers ranking for 3Q2013 with 1.13 Bcf/d of sales, down 25% from its total in 3Q2012 of 1.5 Bcf/d. Tenaska ranked No. 6 in the latest quarter for which figures are available with 6.4 Bcf/d of sales, down 3% from its 6.6 Bcf/d total in 3Q2012.

The Omaha-based parent company, Gavilon Holdings LLC, has been split up over the last year with the agricultural commodities part of the business going last July to Japan’s Marubeni Corp. for $2.7 billion.

Then in December, NGL Energy Partners LP announced it had completed the acquisition of the company’s diversified midstream energy business owned by funds managed by Ospraie Management, General Atlantic and Soros Fund Management. The Gavilon energy interests principally involved integrated crude oil storage, terminal and pipeline assets in Oklahoma, Texas and Louisiana, along with a complementary crude oil and refined products supply, marketing and logistics business.
