N.J. Admin. Code § 7:27-18.7 - Determination of a net emission increase or a significant net emission increase

(a) Any calculation to determine whether the maximum allowable emissions proposed in an application for a permit would result in a net emission increase or significant net emission increase at the facility of any air contaminant listed in Table 3 below shall be conducted in accordance with the following:

1. Determine the net emission increase of each air contaminant listed in Table 3 using the following formula:

NI = IP + INP + IF + IA - DO - DC

Where:
NI =	The net emission increase at a facility
IP =	Any increase(s) in the allowable emissions of the air
contaminant which occurred during the contemporaneous period
and which were authorized by permits issued by the Department;
INP =	Any increase(s) in the allowable emissions of the air
contaminant which occurred during the contemporaneous period
and which came from any equipment or control apparatus for
which no permit was in effect at the time of the increase;
IF =	Any increase in fugitive emissions of the air contaminant from
the facility during the contemporaneous period;
IA =	Any proposed increase in allowable emissions of the air
contaminant from the newly constructed, reconstructed, or
modified equipment or control apparatus which is the subject
of the permit application;
DO =	Any increase(s) in the allowable emissions of the air
contaminant which occurred during the contemporaneous period,
if emission offsets were secured for these increases from the
facility or from another facility; and
DC =	The sum of all creditable emissions reductions at the facility
during the contemporaneous period, not including any
creditable emissions reductions previously used as emission
offsets at the facility or any other facility.

2. Compare the net emission increase of each air contaminant, derived pursuant to (a)1 above, to the significant net emission increase level for that air contaminant set forth in Table 3 below. If the net emission increase is equal to or greater than the applicable significant net emission increase level, it is a significant net emission increase.

TABLE 3 SIGNIFICANT NET EMISSION INCREASES

Air Contaminant	Significant Net Emission Increase Levels (tons per year)
SO[2]	40
SO[2] (as a PM[2.5] precursor)	40
TSP	25
PM[10]	15
PM[2.5]	10
NO[x]	25
NO[x] (as a PM[2.5] precursor)	40
CO	100
Pb	0.6
VOC	25
