# 1 MEMORANDUM

DATE: April 2 1
, 201 5

SUBJECT: Revised Development of the Risk and Technology Review (RTR) Emissions Dataset for the Ferroalloys Production Source Category for the 201 5 Final Rule

FROM: Bradley Nelson, EC/R, Inc.

TO: Phil Mulrine , EPA OAQPS/SPPD/MMG

1.0 PURPOSE

The purpose of this memorandum is to document the methodologies used to estimate pollutant emissions from processes at two ferroalloy facilities ; Eramet Marietta Inc. (Eramet) and Felman Production (Felman)

. The emission estimates developed in this task were used to create a database that will be used as input to the risk assessment modeling to estimate the risks due to emissions from these facilities as part of the “risk and technology” (RTR) review for the Ferroalloy Production source category. This analysis supplements the original and revised RTR analys e s 1
, 2 

# that supported proposed amendments to the national emission standards for hazardous air pollutants (NESHAP) for the ferroalloys production source category published in the Federal Register on November 23, 2011 (76 FR 72508) and supplemental proposed amendments published in the Federal Register on October 10 , 201 4 (7 9 FR 60238 ).

Emissions data have been re

- calculated incorporating newly provided test data 3
, 4
, 5 

# received prior to and after the publication of the 2014 supplemental propos al

. The three test reports are available in the docket for this action (EPA

- HQ

- OAR

- 2010

- 0895). Two test reports provide HAP data for polycyclic aromatic hydrocarbons (PAH) and mercury (Hg) from each of the operational furnaces ;

2 .0 REVISIONS TO THE FERROALLOYS RTR EMISSION ESTIMATES

This section details revisions to the RTR emissions dataset for the Ferroalloys NESHAP for the 2015 Final Rule. Other d etails of the methodology used for developing the emission estimates are unchanged, and are detailed in Revised Development of the Risk and Technology Review (RTR) Emissions Dataset for the Ferroalloys Production Source Category for the 2014 Supplemental Proposal , which is in the docket.

. 1 Furnace Tap ping /Casting Fugitive Emission Factor s

Table 2

- 1 details the revised organic HAP emission factors for tapping and casting operations at Ferroalloys Production Facilities. These factors have been updated to incorporate additional test data including PM em issions from the tapping baghouse on furnace 1 at Eramet.

2.2 Estimated PAH Emissions

The PAH emissions from the furnaces vary depending on the product (e.g., FeMn, SiMn) being produced in the furnace. Table 2

- 2 details the estimated PAH emissions for SiMn production operations at Eramet's furnace 1. For Furnace 12, the PAH data set includes two tests during SiMn production and two tests during FeMn production. However, the Furnace 1 PAH data set only includes two tests conducted during FeMn and n o test data during SiMn production. To address this issue, the test data from Furnace 12 during SiMn production were used to estimate the PAH emissions from Furnace 1 during SiMn production. The PAH emissions estimate was prepared by applying the average measured exhaust flow rate from Furnace 1 to the av erage PAH compound concentrations of the two available PAH test runs performed on Furnace 12 during SiMn production.
