Section 7:27-19.9 - Asphalt pavement production plants
(a) The owner or operator of an asphalt pavement production plant shall cause it to emit NO[x] at a rate no greater than the applicable maximum allowable NO[x] emission concentrations specified in Table 11 below, in accordance with the schedule specified at (f) below.

TABLE 11
Maximum Allowable NO[x] Emission Concentrations for Asphalt
Pavement Production Plants(ppmvd at seven percent O[2])
Fuel TypeNO[x]Emission Concentration
Natural gas75
No. 2 fuel oil100
No. 4 fuel oil, heavier fuel oils or on-specification used oil or any mixture of these three oils125

(b) At least annually, the owner or operator of an asphalt pavement production plant subject to (a) above shall adjust the combustion process of the aggregate dryer in accordance with 7:27-19.16.
(c) In lieu of complying with a NO[x] emission limit under (a) above, the owner or operator of an asphalt pavement production plant may comply with 7:27-19.3(f).
(d) The owner or operator of an asphalt pavement production plant shall perform the following best management practices:
1. Reduce aggregate moisture content by:
i. Covering the aggregate stockpile to prevent high water content due to rain; or
ii. Designing and operating stockpiles for water drainage and removing sand and aggregate from piles at a sufficient height above the base to avoid charging wet mix to the dryer;
2. Conduct monthly inspections of the flights in the dryer when the dryer is in use to determine the degree of wear and the need for replacement. If necessary, replace or modify a flight with an appropriate flight for the applicable combustion zone; and
3. Annually inspect the air system and repair air system leaks to minimize excess air.
(e) The owner or operator of an asphalt pavement production plant shall record and maintain onsite logs of the implementation of the best management practices required in (d) above. Each record shall be maintained in accordance with 7:27-19.19.
(f) The owner or operator of an asphalt pavement production plant shall comply with the NO[x] emission concentrations at (a) above in accordance with the following schedule:
1. An asphalt pavement production dryer with a maximum gross heat input rate of less than 100 MMBTU/hr, shall comply:
i. On and after May 1, 2011, if compliance is achieved without physically modifying the dryer; or
ii. On and after May 1, 2012, if compliance is achieved by physically modifying the dryer.
2. An asphalt pavement production dryer with a maximum gross heat input of at least 100 MMBTU/hr, shall comply:
i. On and after May 1, 2010, if compliance is achieved without physically modifying the dryer; or
ii. On and after May 1, 2011, if compliance is achieved by physically modifying the dryer.
