Section 7:27-19.8 - Stationary reciprocating engines
(a) The owner or operator of a rich-burn stationary reciprocating engine capable of producing an output of 500 brake horsepower or greater, fueled by gaseous fuel, shall cause it to emit no more than 1.5 grams of NO per bhp-hr. Beginning March 7, 2007, a rich-burn stationary reciprocating engine capable of producing an output of 37 kW or greater, fueled by gaseous fuel, and used for generating electricity, is subject to (e) below, and not to this subsection.
(b) The owner or operator of a lean-burn stationary reciprocating engine capable of producing an output of 500 brake horsepower or greater, fueled by gaseous fuel, shall cause it to emit no more than 2.5 grams of NO per horsepower bhp-hr. Beginning March 7, 2007, a lean-burn stationary reciprocating engine capable of producing an output of 37 kW or greater, fueled by gaseous fuel, and used for generating electricity, is subject to (e) below, and not to this subsection.
(c) The owner or operator of a lean-burn stationary reciprocating engine capable of producing an output of 500 brake horsepower or greater, fueled by liquid fuel, shall cause it to emit no more than 8.0 grams of NO per bhp-hr. Beginning March 7, 2007, a lean-burn stationary reciprocating engine capable of producing an output of 37 kW or greater, fueled by liquid fuel, and used for generating electricity, is subject to (e) below, and not to this subsection.
(d) In lieu of complying with a NO[x] emission limit under (a), (b) or (c) above, the owner or operator of a stationary reciprocating engine may comply with 7:27-19.3(f).
(e) On and after March 7, 2007, the owner or operator of a stationary reciprocating engine used for generating electricity whether or not it is located at a major NO[x]facility, shall meet the following requirements, unless the owner or operator is complying with 7:27-19.3(f):
1. For an engine that has a maximum rated power output of 148 kW or greater, cause it to emit NO[x]at a rate no greater than the applicable maximum allowable NO[x]emission rate specified in Table 10 below;

TABLE 10
Maximum Allowable NO
[x] Emission Rates for Stationary Reciprocating Engines
Applicable to Paragraph (e)1 above and (e)4 below Used for Generating Electricity
Engine/FuelTypeMaximum Allowable NO[x] Emission Rate (grams per Bhp-hr)
Rich - Burn fueled by Gaseous or Liquid Fuel1.5
Lean - Burn
1.5 or an emission rate which is equivalent to 80 percent NO[x] reduction from the uncontrolled NO[x] emission level
Lean-Burn fueled by Liquid Fuel2.3
Lean-Burn fueled by Dual-Fuels (gas and liquid fuel)2.3

2. For an engine that has a maximum rated power output of 37 kW or greater and that has commenced operation at the facility on or after March 7, 2007, cause it to emit NO[x]at a rate no greater than 0.90 grams per bhp-hr;
3. For an engine that has a maximum rated power output of 37 kW or greater and that has been modified on or after March 7, 2007, cause it to emit NO[x] at a rate no greater than 0.90 grams per bhp-hr or an emission rate which is equivalent to a 90 percent NO[x] reduction from the uncontrolled NO[x]emission level;
4. For a group of two or more stationary reciprocating engines, each of which has a rated power output of 37 kW or greater, but less than 148 kW, and whose total combined power output is 148 kW or greater, cause it to emit NO[x] at a rate no greater than the applicable maximum allowable NO[x] emission rate specified in Table 10 above.
5. For a modified engine to take advantage of a percent reduction standard specified in Table 10 at (e)1 above, or (e)3 above in lieu of the default emission standard, the equivalent grams per bhp-hr limit must be incorporated into a Preconstruction Permit or Operating Permit. To support the permit application, a stack test conducted in accordance with 7:27-19.15(a)2, utilizing a protocol developed using the protocol templates in Technical Manual 1004, available at the Department's website at http://www.state.nj.us/dep/aqpp/techman.html, must be used to establish the baseline emission rate prior to modification. The engine must have had the combustion processes adjusted using the procedures at 7:27-19.16 prior to the stack test. The protocol and test results must be approved by the Bureau of Technical Services (BTS).
(f) The owner or operator of any stationary reciprocating engine that has a maximum rated power output of at least 37 kW or greater, used for generating electricity, and whether or not it is located at a major NO[x] facility, shall adjust the engine's combustion process in accordance with the procedures set forth at 7:27-19.16 and the following schedule:
1. For stationary reciprocating engine that has a maximum rated power output of at least 37 kW but less than 370 kW used for generating electricity, according to manufacturer's recommended maintenance schedules beginning in 2007: or
2. For stationary reciprocating engine that has a maximum rated power output of at least 370 kW or greater, or required prior to November 7, 2005 to adjust the combustion process, according to manufacturer's recommended maintenance schedules.
