Respondent owns an ice production operation and two refrigerated warehousing storage operations which consist of two separate ammonia closed-loop refrigeration system processes. Both processes have refrigerated and frozen storage space using industry standard mechanical refrigeration designs including multiple cooling coils (evaporators), heat rejection towers (condensers), rotary screw compressors, and ammonia service pressure vessels. At the single Stationary Source, Respondent has two RMProgram level 3 covered processes which store or otherwise use anhydrous ammonia in amounts exceeding its applicable threshold of 10,000 pounds. During calendar year 2013, EPA opened an RMProgram compliance monitoring investigation to determine Respondent’s compliance with 40 C.F.R. Part 68. As part of this investigation, EPA conducted an onsite inspection of RMProgram related records and equipment on April 30th and May 1st of 2013. The focus of the onsite inspection was to assess Respondent’s compliance with RMProgram requirements for its covered processes operating at its Stationary Source.
