An Arizona water district has withdrawn its request for a swift ruling on its claims that Honeywell and four other defendants must help pay cleanup costs for contamination of local well water, a move that follows a federal judge's decision allowing the defendants additional time to conduct discovery and respond to the request.

In a filing Monday in the $42 million suit, the Roosevelt Irrigation District withdrew its motion for partial summary judgment, in which the water district had asked U.S. District Judge David Alan Ezra to rule that five of the defendants in the case — Honeywell, Union Pacific Railroad Co., Arizona Public Service Co., Maricopa County and Meritor Inc. — were liable for cleanup costs under the Comprehensive Environmental Response, Compensation and Liability Act.

The defendants — Air Liquide America Specialty Gases LLC, Arizona Public Service Co., ChemResearch Co. Inc., the city of Phoenix, Corning Inc., Dolphin Inc., Freescale Semiconductor Inc., Honeywell International Inc., ITT Corp., Kinder Morgan Energy Partners LP, Maricopa County, Meritor Inc., Nucor Corp., Prudential Overall Supply, Reynolds Metals Co., Salt River Project Agricultural Improvement and Power District, Textron Inc., Union Pacific Railroad Co. and Univar USA Inc. — are represented by Ballard Spahr LLP as well as several additional law firms.
