No change in potential emissions for EPN 1-12 since this is a baghouse and emissions are based on outlet grain loading and exhaust flow rate.

1 FINs 1-12 and 1-13 (elevator and enclosed conveyor) are not affected by the proposed project. No change in potential emissions for EPN 1-12 since this is a baghouse and emissions are based on outlet grain loading and exhaust flow rate.

2 Since the MAERT for Permit No. 1 has an SO2 emission rate limit for EPNs 2, 6, and 12 combined, the combined short-term and annual SO2 emission rates from EPNs 2, 6, and 12 are divided by 3 to represent emission rates for each kiln.

3 PM10 emission rate not specifically quantified on Permit No. 1 MAERT. PM10 emission rate is the front half (FH) PM emission rate from the MAERT times the particle size distribution factor of 0.85 from AP-42, Section 11.6, Table 11.6-5, (January 1995) plus the back half emission rate (assumes that all back half emissions are PM2.5)

 The back half emission rate is determined as the PM(Total) minus PM(FH) from Permit No. 1.

4 PM2.5 emission rate not specifically quantified on Permit No. 1 MAERT. PM2.5 emission rate is the front half (FH) PM emission rate from the MAERT times the particle size distribution factor of 0.64 from AP-42, Section 11.6, Table 11.6-5, (January 1995) plus the back half emission rate (assumes that all back half emissions are PM2.5)

 The back half emission rate is determined as the PM(Total) minus PM(FH) from Permit No. 1.

5 Emission rate not specifically quantified on Permit No. 1 MAERT. Emission rate is the maximum emission rate (lbs/ton clinker) among all three kilns determined from July 2003 stack testing multiplied by the maximum hourly and annual clinker production rates from Permit No. 1 MAERT.

6 Emission rate not specifically quantified on Permit No. 1 MAERT. Emission rate is the maximum emission rate (lbs/ton clinker) among all three kilns determined from March 2001 stack testing multiplied by the maximum hourly and annual clinker production rates from Permit No. 1 MAERT.

7 PM10 and/or PM2.5 emission rate not specifically quantified on Permit No. 1. Since the emission point is controlled by a fabric filter dust collector, PM10 and/or PM2.5 emissions are assumed to be the same as PM emissions.

8 PM2.5 emission rate not specifically quantified on Permit No. 1 MAERT. Since PM and PM10 emissions in Permit No. 1 MAERT are based on AP-42 Section 13.2.4, the PM2.5 emission rate is determined based on the k factors for PM2.5 of 0.053.

9 EPN is combined with other EPNs on the MAERT. The emission rate for F-MB2 was obtained from the August 2003 Permit Amendment application for Grandfathered Sources.

10 EPN is combined with other EPNs on the MAERT. The emission rate for each individual EPN was obtained from the December 2003 Permit Renewal application, Appendix B.

11 Some emission rates are shown as <0.01 on MAERT. Emission rates obtained from December 2003 Permit Renewal application, Appendix C.

E = k * 0.0032 * (U / 5)1.3 / (M / 2)1.4

E = Emission factor (lb/ton)

k = Particle size multiplier (0.74 for PM, 0.35 for PM10, and 0.053 for PM2.5)

U = Sheltered Mean wind speed (miles per hour) = 1 mph

a FIN-Specific PTE

b EPN-specific PTE using most restrictive limits from FIN-specific PTE

c Annual compliance PTE is based on NSPS subpart Y limit.

d Hourly PTE based on NSPS subpart Y limit.

e Emissions for this Emission Unit (FIN) was calculated based on an AP 42 emission factor. The emission factor is not a compliance limit. Therefore, it does not restrict the EPN (stack) to a limit.

f PTE is based on dispersion modeling. Project impacts will remain below applicable Significant Impact Levels (SIL's)

g Emission unit is not subject to a relevant NESHAP or NSPS limit.

h Vendor emissions data was scaled by 350%. Result is less than BACT.

i Hourly PTE based on THC emission limit in NESHAP subpart LLL

j PTE is sum of emissions from all Emission Units venting through this stack.

k Assumed PM2.5 = PM10 = PM

l Emission factor is multiplied by diesel fuel sulfur content, S1. S1 is assumed to be 0.5% sulfur.

m Used non-methane TOC emission factor from AP42 Table 3.4-1 (i.e., TOC is by weight 91% nonmethane)

Nomenclature:

PMf = Total filterable particulate matter

PM10f = Filterable particulate matter less than 10 μg

PM2.5f = Filterable particulate matter less than 2.5 μg

PM2.5c = Condensable particulate matter less than 2.5 μg (all condensable PM are assumed to be less than 2.5 μg)

PM = PMf

 + PM2.5c

PM10 = PM10f + PM2.5c

PM2.5 = PM2.5f + PM2.5c

Note:

This system includes a kiln, and an in-line dryer crusher, precalciner and preheater.

All of these units are considered together because emissions from this system are vented through a common baghouse and stack.
