25 Pa. Code § 127.210 - Offset ratios

(a) The emissions offset ratios for NSR purposes and ERC transactions subject to the requirements of this subchapter must be in an amount equal to or greater than the ratios specified in the following table:

Required Emission Offsets For Existing Sources, Expressed in Tons per Year

Pollutant/Area	Flue Emissions	Fugitive Emissions
PM-10 and SOx	1.3:1	5:1
Volatile Organic Compounds
Ozone Classification Areas
Severe Areas	1.3:1	1.3:1
Serious Areas	1.2:1	1.3:1
Moderate Areas	1.15:1	1.3:1
Marginal/Incomplete Data Areas	1.15:1	1.3:1
Transport Region	1.15:1	1.3:1
NOx
Ozone Classification Areas
Severe Areas	1.3:1	1.3:1
Serious Areas	1.2:1	1.2:1
Moderate Areas	1.15:1	1.15:1
Marginal/Incomplete Data Areas	1.15:1	1.15:1
Transport Region	1.15:1	1.15:1
Carbon Monoxide
Primary Nonattainment Areas	1.1:1	1.1:1
Lead	1.1:1	1.1:1
PM2.5
PM2.5 Nonattainment Area
PM2.5	1:1	1:1
PM2.5 Precursors
SO2	1:1	1:1
NOx	1:1	1:1
VOCs	1:1	1:1
Ammonia	1:1	1:1

(b) In complying with the emissions offset requirements of this subchapter, the emission offsets obtained shall be of the same NSR regulated pollutant unless interpollutant offsetting is authorized for a particular pollutant in accordance with subsection (c).

(c) The Department may, based on a technical assessment, establish interpollutant trading ratios for offsetting PM_2.5 emissions or PM_2.5 precursor emissions in a specific nonattainment area or geographic area in this Commonwealth. The interpollutant trading ratios shall be subject to public review and comment for at least 30 days prior to submission to the EPA for approval as a SIP revision.

(d) If the EPA promulgates PM_2.5 interpollutant trading ratios in 40 CFR Part 51 (relating to requirements for preparation, adoption, and submittal of implementation plans), the ratios will be adopted and incorporated by reference.
