(3) Reportable incidents. This is a department informational note to be used under ANSI/ASHRAE standard 15 section 11.7, paragraph c:
SPS 345.511 Note
Note: Refrigerants typically should not be discharged except in an emergency. The Department of Natural Resources, federal agencies and local fire departments may have requirements relating to being immediately notified upon the automatic or manual discharge of specified amounts of any refrigerant.
SPS 345.511 Note
Notification may not be necessary for any of the following conditions:
SPS 345.511 Note
1. Refrigeration systems operating at pressures below atmospheric and incorporating automatic purge systems.
SPS 345.511 Note
2. Incidental operation of automatic pressure relief valves resulting in minor release of the refrigerant charge.
SPS 345.511 Note
3. Incidental minor releases associated with service operations after system pump-down has been accomplished.

(1)
Discharge capacity of plate heat exchangers. This is a department alternative to the requirements in ANSI/IIAR 2 section 11.2.7:
The minimum required relief device capacity for a plate heat exchanger based on an external heat addition scenario may be calculated in accordance with the following equation:
where:
Cr,plate HX = minimum required relief device capacity for the
plate heat exchanger (lbm/min of air)
f = relief device capacity factor
L = length of the plate pack (ft)
W = width of the plate pack (ft)
H = height of the plate pack (ft)

SPS 345.70 Ozone-depleting refrigerants. SPS 345.70(1)(1)
Cleaning of equipment. Ozone-depleting refrigerant may not be used for cleaning purposes, including the cleaning of interior or exterior surfaces of refrigeration equipment.
SPS 345.70(2)
(2) Transferring refrigerant. Whenever ozone-depleting refrigerant is removed from refrigeration equipment, the ozone-depleting refrigerant shall be transferred to storage containers using equipment that is approved by the department. The department shall approve any transfer equipment if an approved nationally recognized testing laboratory has certified the equipment.
SPS 345.70 Note
Note: The Department will accept equipment that has been tested and certified in accordance with the Air-Conditioning and Refrigeration Institute (ARI) standard ARI 740.
SPS 345.70(3)
(3) Releasing refrigerant. Ozone-depleting refrigerant may not be knowingly or negligently released to the environment, except for minimal releases that occur as a result of efforts to recover, reclaim or recycle ozone-depleting refrigerant removed from refrigeration equipment.
SPS 345.70(4)
(4) Adding refrigerant. Before putting additional ozone-depleting refrigerant into refrigeration equipment, the refrigeration equipment shall be inspected and repaired if a leak is found or suspected. A yearly leak rate identified by the federal environmental protection agency shall be used to determine whether repairs are necessary.
