National Emissions Standards for Hazardous Air Pollutants From 
Secondary Lead Smelting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule amendments.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
amendments to a final rule that revised national emission standards for 
hazardous air pollutants for existing and new secondary lead smelters. 
The final rule was published on January 5, 2012. This action proposes 
amendments to clarify certain regulatory text related to compliance 
dates. Additionally, we are proposing amendments to clarify certain 
provisions in the 2012 final rule relating to monitoring of negative 
pressure in total enclosures. This action also proposes corrections of 
typographical errors in a table listing congeners of dioxins and furans 
and testing requirements for total hydrocarbons.

DATES: Comments. Comments must be received on or before February 3, 
2014, or 30 days after date of public hearing, if one is requested. If 
anyone contacts the EPA requesting a public hearing by January 10, 
2014, the EPA will announce the details as to when the hearing will be 
held in a separate Federal Register notice.
    Public Hearing. The EPA will hold a public hearing on this proposed 
rule if requested. Requests for a hearing must be made by January 10, 
2014. Contact Nathan Topham at topham.nathan@epa.gov or (919) 541-0483

I. General Information

A. Does this action apply to me?

    The regulated industrial source category that is the subject of 
this proposal is listed in Table 1 of this preamble. Table 1 of this 
preamble is not intended to be exhaustive, but rather provides a guide 
for readers regarding the entities likely to be affected by this 
proposed action. These standards, once finalized, will be directly 
applicable to affected sources. Federal, state, local and tribal 
government entities are not affected by this proposed action. As 
defined in the source category listing report published by the EPA in 
1992, the Secondary Lead Smelting source category is defined as any 
facility at which lead-bearing scrap materials (including, but not 
limited to lead acid batteries) are recycled by smelting into elemental 
lead or lead alloys.\1\

C. What is the background for the proposed amendments?

    On January 5, 2012 (77 FR 556), the EPA issued final amendments to 
the National Emissions Standards for Hazardous Air Pollutants (NESHAP) 
from Secondary Lead Smelting. The EPA has subsequently determined, 
following discussions with affected parties, that the final rule 
warrants clarification in four areas.
    The EPA inadvertently removed from 40 CFR part 63, subpart X the 
requirement for facilities constructed or reconstructed on or before 
May 19, 2011, to comply with the previous version of the NESHAP between 
promulgation of the January 5, 2012, amendments and the subsequent 
compliance date for existing sources, which is January 6, 2014. Since 
existing sources remain subject to the pre-existing standards until the 
compliance date for the January 2012 standards, the EPA is amending the 
rule to restore the deleted language.
    The EPA received petitions for reconsideration of the final rule 
from the secondary lead smelting industry. One issue raised in the 
petitions relates to the table of dioxin and furan congeners contained 
in the regulatory text (Table 3 to Subpart X of Part 63--Toxic 
Equivalency Factors). This table included incorrect values for some 
dioxin toxic equivalency factors (TEF) and omitted some congeners. The 
EPA intended to use the 2005 World Health Organization (WHO) TEF in 
Table 3 to subpart X of part 63. See 76 FR 29051, ``The TEQ emissions 
will be calculated using the toxic equivalency factors (TEF) outlined 
by the World Health Organization (WHO) in 2005 (available at Web site: 
http://www.epa.gov/raf/hhtefguidance/).''
    Industry petitioners expressed concern that the agency changed one 
aspect of the emission standard for total hydrocarbons (THC) between 
proposing and finalizing the RTR amendments for secondary lead 
smelters. In the 2011 proposed rule, the total hydrocarbon standard for 
furnace charging process fugitive emissions that are not combined with 
furnace process emissions did not require correction to 4-percent 
carbon dioxide (CO2). See 76 FR 29072, May 19, 2011. In the 
2012 final rule, this standard inadvertently included correction to 4-
percent CO2. See 77 FR 582, January 5, 2012.
    Finally, petitioners asked the EPA to clarify several monitoring 
provisions for total enclosures. Industry requested

[[Page 381]]

flexibility in defining the term ``windward wall'' when a total 
enclosure is not impacted by ambient wind. The regulatory text was 
unclear where to place monitors when ambient wind does not affect the 
total enclosure. Petitioners requested clarification in how to monitor 
irregularly shaped enclosures or enclosures that are divided into 
multiple areas all under negative pressure. Petitioners also asked the 
EPA to clarify that data from differential pressure monitors should be 
used to calculate 15-minute averages. Petitioners also stated that the 
EPA should clarify the meaning of ``accuracy'' in 40 CFR 63.548(k)(3).

II. Direct Final Rule

    A direct final rule that would make the same changes as those 
proposed in this document appears in the Rules and Regulations section 
of this Federal Register. The EPA is taking direct final action on 
these amendments because we view the amendments as noncontroversial and 
anticipate no significant adverse comments. The EPA has explained our 
reasons for the amendments in the direct final rule. If no significant 
adverse comments are received, no further action will be taken on the 
proposal, and the direct final rule will become effective as provided 
in that action.
    If the EPA receives significant adverse comments, we will withdraw 
only those provisions on which we received those comments. The EPA will 
publish a timely withdrawal in the Federal Register indicating which 
provisions will become effective, and which provisions are being 
withdrawn. If part or the entire direct final rule in the Rules and 
Regulations section of this Federal Register is withdrawn, all comments 
pertaining to those provisions will be addressed in a subsequent final 
rule based on these proposed amendments. The EPA will not institute a 
second comment period on the subsequent final action. Any parties 
interested in commenting must do so at this time.
    The changes to the regulatory text proposed in this notice are 
identical to those for the direct final rule published in the Rules and 
Regulations section of this Federal Register. For further information, 
including the detailed rationale for the proposal and the regulatory 
revisions, see the direct final rule published in a separate part of 
this Federal Register.

III. Statutory and Executive Order Reviews
