- 1: Annual Standard Attainment Test

The annual standard attainment test s for Liberty and Clairton are given in this section. Calculations are based on the steps listed in the attainment

test methodology section , taken from EPA Modeling Guidance

. Below is a key to terms used in the subsequent charts for the attainment tests

. [ Note: Substitute Clairton (CL) FRM for Liberty (LB) FRM for the Clairton tests .]

TERMS

LB_FRMw Liberty FRM weighted average concentration (baseline)

LB_FRMc Liberty FRM concentration, concurrent with speciation samples

LB_FRMf Liberty FRM futu re projected concentration

Blank Passive blank mass (constant)

Non

- Blank Sum of all species but passive blank

OCMmb Organic Carbon Mass by mass balance (FRM minus other species)

OC Organic Carbon (measured)

OCfloor Organic Carbon floor (OC*1.4*0.7)

E C Elemental Carbon (measured)

TotalC Elemental + Organic Carbon (modeled or calculated)

SO4 Sulfate (modeled or measured)

NO3r Retained Nitrate, calculated by EPA using PIT temp and relative humidity

NO3 Nitrate (modeled or measured)

NH4r Retained (or Indirect) Ammonium, calculated from DON, sulfate, and retained

PBWcalc Particle Bound Water, calculated by polynomial fitted to AIM

DON Degree of Neutralization

Crustal(alt) Crustal Component, calculated from Si, Ti, Ca, and Fe (not Al)

OPP Ot her Primary PM2.5 (analogous to alternative crustal and A25 from CMAQ)

The 24

- hour attainment test s for Liberty and Clairton are given in this section. Calculations are based on the steps listed in the attainment test

methodology section, taken from EPA Modeling Guidance. Species reconstruction calculat ions are similar to the steps used for the annual test.

However, the analysis is based on modeled and observed high days rather than averages. Below is a key to terms used in the s ubsequent charts

for the attainment tests. [Note: Substitute Clairton (CL ) FRM for Liberty (LB) FRM for the Clairton tests.]

Methodology:

- Assume Liberty sp ecies compositions are representative of Clairton (but at smaller concentrations)

- Use measured SO4 and EC

- Use retained nitrate (calculated)

- Use calculated indirect NH4 (retained) method for baseline and future

- Use crustal (alt) for other particulate PM2.5 (OPP)

- Use calculated particle bound water for baseline and future

- Degrees of Neutralization (DON) constant from base to future

- Apply quarterly relative co mpositions to each quarterly high day in 5

- 3: Impact Tables

Impacts by source or source group for the modeled recepto r grids are shown in the tables below.

These tables are given to d isplay annual and 24

- hour maximum impacts f r om individual

sources / groups for comparative purposes. They do not reflect the exact quarterly and daily

averaging that were used in the attainm ent tests given above

. I mpacts from the equivalent and

nearby grids were combined on a concurrent basis for use in the attainment tests.

Note: Annual average impacts from different source groups can be summed cumulatively. 24

- hour impacts cannot be sum med in the same way due to the possibility that maximums for

individual source groups can occur on different days.
