PAMS – means Photochemical Assessment Monitoring Station.

Particles – means any material, except uncombined water, which exists as liquid particles or solid particles at standard conditions.

PM2.5 – means a class of air contaminants, which includes all particulate matter having an aerodynamic diameter less than or equal to a nominal 2.5 microns.

PM10 – A criteria air pollutant; Means a class of air contaminants, which includes all particulate matter having an aerodynamic diameter less than or equal to a nominal 10 microns. Particulate matter includes dust, soot and other tiny bits of solid materials that are released into and move around in the air. Particulates are produced by many sources, including burning of diesel fuels by trucks and buses, incineration of garbage, mixing and application of fertilizers and pesticides, road construction, industrial processes such as steel making, mining operations, agricultural burning (field and slash burning), and operation of fireplaces and woodstoves. Particulate pollution can cause eye, nose and throat irritation and other health problems.

Peak Ozone Season – means June 1 through August 31, inclusive.

Permit – means any permit issued pursuant to the requirements established under the Air Pollution Control Act, N.J.S.A. 26:C-1 et seq., or N.J.A.C. 7:27-1 et seq., except to the extent that the permit includes any prohibition established solely pursuant to N.J.A.C. 7:27-8.8(f).

PJM – means PJM Interconnection LLC, or any successor to PJM as the Regional Transmission Organization, approved by the Federal Energy Regulatory Commission (FERC), serving a region that includes New Jersey as well as all or parts of other states.

Point Source Air Emissions - As defined in 40 CFR 51.50, point sources are large, stationary (non-mobile), identifiable sources of emissions that release pollutants into the atmosphere. A point source in New Jersey includes, but is not limited to, a facility that is a major source under 40 CFR part 70 for one or more of the pollutants for which reporting is required by 40 CFR 51.15 (a)(1). This does not include the emissions of hazardous air pollutants, which are not considered in determining whether a source is a point source for ozone, PM2.5, and regional haze emissions inventory development and reporting. These point sources can be associated with a single point or group of points in space. Examples of important point source emissions categories include power plants, industrial boilers, petroleum refineries, cement plants, and other industrial plants.

In New Jersey, a point source is defined as a stationary facility that emits or has the potential to emit at or above any of the following thresholds:

•          10 tons per year of VOC
•          25 tons per year of NOx
•          100 tons per year of carbon monoxide, PM2.5, PM10, SO2, ammonia

Pollutants – unwanted chemicals or other material found in the air. Pollutants can harm health, the environment and property. Many air pollutants occur as gases or vapors, but some are very tiny solid particles: dust, smoke, or soot.

Potential to Emit – means the maximum aggregate capacity of a source operation or of a facility to emit an air contaminant under its physical or operational design. Any physical or operational limitation on the capacity of a source operation or a facility to emit an air contaminant, including control apparatus, and restrictions on hours of operation or on the type or amount of material combusted, stored or processed, shall be treated as part of its design if the limitation is federally enforceable. If there is no federally enforceable limitation on the hours of operation of a course operation, then any determination of the maximum design capacity shall be based on a presumption of operation at 8760 hours per year. This term includes the fugitive emissions emitted by the source operation or facility as calculated in a manner consistent with the provisions of N.J.A.C. 7:27-21 and current guidance issued by the Department pursuant thereto.

Precursor – In photochemistry, a compound antecedent to a pollutant. For example, volatile organic compounds (VOCs) and nitrogen oxides react in sunlight to form ozone or other photochemical oxidants. As such, VOCs and oxides of nitrogen are precursors.

Primary Standard – A pollution limit based on health effects. Primary standards are set for criteria air pollutants.
