OMB No. 2050-0086To calculate the SSI trigger (i.e., the upper bound of the normal range of a release) for each hazardous substance identified below, aggregate the upper bounds of the normal range of the identified hazardous substance across all animal waste sources identified in Section II, Part C.

Animal Waste Source				 Upper Bound of the Normal Range of the Release in Pounds



Animal Waste Source				 Upper Bound of the Normal Range of the Release in Pounds

  The CR-ERNS Number is required for this submission. NRC will assign a CR-ERNS number for your farm when you make the initial notification.
 
Use this form to identify the SSI trigger for hazardous substance air releases at your farm. 
                                       
Statistically Significant Increase (SSI) Notification - An SSI is any episodic release of a hazardous substance that exceeds the release quantity delineated in the upper bound of the normal range of the farm's continuous release report.  The normal range is defined to include all the releases of a hazardous substance (from all animal waste sources) occurring over any 24-hour period under normal operating conditions during the preceding year. Only those releases that are both continuous and stable in quantity and rate may be included in the normal range. The aggregated upper bounds of the normal range of each hazardous substance is referred to as the "SSI Trigger."

An SSI in a continuous release of a hazardous substance must be reported to the NRC as soon as the person in charge is aware that the release exceeds the SSI trigger. Because an SSI is a type of episodic release, it is treated as such.

It may be possible to adjust the SSI trigger (i.e., change the normal range of the release) if a particular continuous release frequently exceeds the upper bound of the normal range. 

Calculation of the SSI Trigger for a Hazardous Substance

Hazardous	Upper 
For purposes of this example, it is assumed that the only sources of the hazardous substance release at the farm are Barn #1, Lagoon #1, and Manure Pile #1.

Substance (HS)	Source	Bound	
Name of HS 	Barn #1 	120 lbs
            Lagoon #1 	115 lbs
            Manure Pile #1 	+130 lbs
            
            Upper Bound for HS	= 365 lbs
