Current through Register Vol. 50, No. 6, June 20, 2024
A.
				  Potable water utilized for heat exchangers or compressors on a Grade A dairy
				  farm may be salvaged and used for certain limited applications in the milking
				  operation on the dairy farm if the following criteria are met:
1. The reclaimed
				  waterdf piping system shall meet the requirements of
				  Parts XII and XIV of this Code.
2.
				  Any re-circulated cold reclaimed waterdf which is used
				  in exchangers, including systems in which a freezing point depressant is used,
				  shall be from a safe source and protected from contamination. Such reclaimed
				  waterdf shall be tested at the minimum frequencies
				  specified in this Section and shall otherwise comply with any other
				  requirements of this Section. Freezing point depressants shall be
				  non-toxic.
3. The reclaimed
				  waterdf shall be stored in a storage vessel properly
				  constructed of such material that will not contaminate the reclaimed
				  waterdf system and will protect the system from possible
				  contamination.
4. The storage
				  vessel shall be equipped with a drain and access point to allow for
				  cleaning.
5. No cross-connection
				  shall exist between the reclaimed waterdf supply and any
				  unsafe or questionable water supply or any other source of pollution. No cross
				  connection shall exist between any potable water supply or potable water
				  distribution system and the reclaimed waterdf
				  system.
6. There are no submerged
				  inlets through which the reclaimed waterdf system may be
				  contaminated.
7. The reclaimed
				  waterdf shall be of satisfactory organoleptic quality
				  and shall have no off flavors or odors.
8. The reclaimed
				  waterdf shall comply with the bacteriological standards
				  of Appendix G, Section I of the PMO.
9. Samples of the reclaimed
				  waterdf shall be collected and analyzed prior to initial
				  approval and semi-annually thereafter.
10. Approved chemicals, such as chlorine,
				  with a suitable retention period, may be used to suppress the development of
				  bacterial growth and prevent the development of tastes and odors in the
				  reclaimed waterdf.
11. When chemicals are added to the reclaimed
				  waterdf, a monitoring program for such added chemicals
				  shall be in effect and such chemicals shall not add substances that will prove
				  deleterious to the use of the reclaimed waterdf or
				  contribute to product contamination.
12. If the reclaimed
				  waterdf is to be used for the sanitizing of teats or
				  equipment (back-flush systems), approved sanitizers, such as iodine may be
				  added by an automatic proportioning device located downstream from the storage
				  vessel but prior to its end-use application. An approved backflow prevention
				  device shall be installed immediately upstream of the point of chemical
				  addition.
