Pacific Coast Producers - Lod Ammonia Refrigeration Anhydrous Ammonia Refrigeration System 1/5/2022 No. F C R Consequence Safeguards and Control Measures Suggested Safeguards and Control Measures Management Response / Action Taken Estimated Completion Date Assigned To Actual Completion Date 4.21 2 2 C Loss of oil cooling associated with the compressors. SC-4 has LIC for oil cooling as a backup. Ammonia detection system inside engine room. SC-4 high temperature cutout. Consider evaluating flow switch to indicate loss of water for oil cooling. Consider evaluating reciprocating compressor high discharge and oil temperature cutout functions. Have a quote and have issued a PO for this. Part to be received by October 15, 2024. Installation by January 1, 2025 Information from SMI log indicates all site flow indicators were replaced and an additional 2 installed October 7, 2022. 10/15/2024 Install 1/1/25 SMI Flow switch completed 12/20/2024 6.01 2 2 C Ammonia release at system pressure, if vessels are not isolated. Procedures for oil draining have been developed by refrigeration contractor. Deadman valves are installed at oil draining locations or a portable deadman valve is used. Oil draining is an attended procedure. Consider acquiring a portable eyewash/shower station, drench hose or an additional fixed installation unit. A portable eyewash station is installed in the compressor room. Jul-22 T. Tran Jul-22 6.03 2 2 C Compromise Personnel safety Two exits from cold rooms. Egress issues not expected. Oil draining conducted prior to season before bins are in the room. Consider the need for a buddy or attendant in addition to the technician for performing oil draining. SOP #111 states this is a one person job. SOP #111 has been updated to state this is a two person job. 10/31/2024 SMI 10/8/2024 7.02 2 3 B If diffusion tank pressure rating is exceeded and fails, potential for ammonia vapor release at system head pressure. If tank doesn't fail and system pressure builds, another component in the system may fail if component pressure ratings are exceeded. PRVs set pressure are equal to or less than vessel MAWP. Manual emergency blowdown switch. Emergency fire control box with equalization valve. See Node for recommendation 4.15. Pressure relief valve calculations provided and show that the valve design is adequate. 10/10/2024 SMI 10/10/2024 7.04 2 4 B Personnel safety, Inadequate notification to facilitate immediate emergency response. PM program includes testing ammonia equipment alarms. Semi annual calibration of ammonia detectors and alarms. Email and text call out for engine room ammonia detectors. Consider upgrading the ammonia detection systems to add in audio/visual alarms outside cold storage rooms, notification on PLC and alarms of a PRV release at the diffusion tank. On 2/15/2024 SMI completed horns/strobes for cold rooms. These are inside the room. There is audio notification. By 10/15/24 SMI will upgrade ammonia detection to add notification on PLC of diffusion tank. 1/1/2025 SMI 2/15/24 Horns/strobes PLC for diffusion tank completed 10/25/2024 8.02 2 3 B Personnel safety Ventilation fan installed in engine room. Consider upgrading the ventilation fan to and updraft fan that meets the ammonia detection activation setpoints and continuous and emergency ventilation flow requirements of IIAR 2. Fan in place meets requirements at the time of installation. Fan has already been converted to an "ON-AUTO" switch. SMI is replacing the fan and motor with nonsparking components. Parts have a 14- week lead time, so this task will be completed by March 2025 Mar-25 SMI Mar-25 8.05 1 1 D Potential damage to ammonia system. Facility is located within 500 year flood zone with an anticipated depth of less than one foot. Consider developing or updating the Flood Emergency Response Plan to include shutdown and/or protection of the ammonia refrigeration system. The ammonia system is only in operation from June - September each year. There is no possibility that a flood event will occur during the time the system is in operation; therefore, the system is in shutdown mode when possibility for flood event to occur. The recommendation is not necessary to protect the health and safety of the employer's own employees, or the employees of contractors. Declined 8.10 1 3 C Potential damage to ammonia system. Design basis of system met seismic restraint requirements at time of construction. Added seismic restraints to piping. Seismic assessment conducted and repairs verified by engineer. Design basis complies with local building code requirements. Consider reaching out to CUPA on when the next seismic assessment revalidation is due. The last seismic assessment follow up was completed in 2019 after the 2016 seismic assessment. Seismic assessment completed in 2022, recommendations completed and engineer re- evaluation completed 9/18/2024. Engineer recommended additional repair of exposed rebar. Photos to engineer on 9/26/24; we will receive the report after photos are provided. Received confirmation report from engineer on 10/10/2024 that recommendations were completed. 9/18/2024 Report received 10/10/2024 8.16 2 3 B Personnel safety and inability to isolate equipment/valves resulting in an increased release potential Emergency stop switch is located outside the engine room. King valves and fire emergency control box are accessible at ground level. See Node 3.12 for recommendation. Valves have been labeled. 0 SMI July 2022 and October 8, 2024 8.18 2 4 B Personnel safety There are no adjoining walls to production areas and the engine room. See Node 7.04 for recommendation. SMI 2/15/24 Horns/strobes 8.19 3 3 B Personnel safety. Ventilation in machine room runs continuously designed to purge machine room. Ammonia detection inside engine room alarms at 25 ppm and has email and text call outs. See Node 4.10 for recommendation. 1/1/2025 (replace fan and motor) 0 9/23/24-Fan switch replaced Updraft fan with nonsparking blades 9.01 2 2 C Corrosion of external surfaces causing a leak. Regular inspection of piping and vessels for corrosion and damaged or failed insulation. Ammonia detecting inside engine room alarms at 25 ppm. Consider repairing piping insulation breaches following the installation of seismic bracing inside engine rooms. Piping insulation breaches repaired (see photos "LCS Insulation", "LCS Sealed Pipes 1" and "LCS Sealed Pipes 2" 1/1/2025 SMI 10/8/2024 9.05 2 3 B Personnel safety. Equipment damage if undersized and increased release potential from damaged equipment. PRVs are replaced every 5 years. See Node 4.15 for recommendation. Pressure relief valve calculations provided and show that the valve design is adequate. 10/10/2024 SMI 10/10/2024 9.06 2 4 B Personnel safety. Equipment damage if undersized and increased release potential from damaged equipment. PRVs are replaced every 5 years. See Node 7.04 for recommendation. On 2/15/2024 SMI completed horns/strobes for cold rooms. These are inside the room. There is audio notification. By 10/15/24 SMI will upgrade ammonia detection to add notification on PLC of diffusion tank. 1/1/2025 SMI 2/15/24 Horns/strobes PLC for diffusion tank completed 10/25/2024 9.16 2 2 C Personnel safety. Eyewash/showers are located inside and outside the engine room. Regular inspection and maintenance of emergency response equipment. See Node 6.01 for recommendation. A portable eyewash station is installed in the compressor room. 7/1/2022 T. Tran 7/1/2022 Table 1 (Recommendations), Page 2
