12VAC5-613-10. Definitions.
 

1.        Add definition for CBOD5 with ratio of BOD5 wherever BOD5 is mentioned.

Reason: NSF Standards 40 and 245 report effluent results in CBOD5.  Also, some manufacturers, as part of their evaluation process, have field sampled for CBOD5.

2.        Add definitions for ammonia, nitrate, TKN and alkalinity.

Reason: The constituents are valuable for gauging field performance and troubleshooting. Furthermore, some of these constituents could be used to gauge compliance as part of a testing protocol, service using field test kits, or compliance with protocols or service using in situ sensors.

3.        Add definitions for Fats, Oils, and Grease (FOG) and High Strength Waste.

Reason: Many residential units or other technologies are misapplied to a variety of commercial situations.  In addition to definitions, criteria needs to be developed in the AOSS to address high strength wastewater and FOG. This is crucial since many commercial properties have very limited land area and the risks associated with public health are higher should a system malfunction or fail.
