I. Background

A. The Lead NAAQS

Under the Clean Air Act (CAA), EPA must establish national ambient air quality standards (NAAQS) for six criteria pollutants, including lead. Lead is generally emitted in the form of particles, which end up being deposited in water, soil, and dust. People may be exposed to lead by inhaling it, or by ingesting lead-contaminated food, water, soil, or dust. Once in the body, lead is quickly absorbed into the bloodstream and can result in a broad range of adverse health effects. These include damage to the central nervous system, cardiovascular function, kidneys, immune system, and red blood cells. Children are particularly vulnerable to lead exposure, in part because they are more likely to ingest lead and in part because their still-developing bodies are more sensitive to the effects of lead. The harmful effects to children's developing nervous systems (including their brains) arising from lead exposure may include IQ loss, poor academic achievement, long-term learning disabilities, and an increased risk of delinquent behavior.

EPA first established a lead standard in 1978 at 1.5 micrograms per meter cubed (µg/m 3) as a quarterly average. (1) Based on new health and scientific data, EPA revised the federal lead standard to 0.15 μg/m 3 and revised the averaging time for the standard on October 15, 2008 (see 73 FR 66964, November 12, 2008). A violation of the standard occurs when ambient lead concentrations exceed 0.15 μg/m 3 averaged over a 3-month rolling period.

The process for designating areas following promulgation of a new or revised NAAQS is contained in section 107(d) of the CAA. The CAA generally requires EPA to complete the initial area designations process within two years of promulgating a new or revised NAAQS. Sixteen areas were designated nonattainment for the 2008 lead NAAQS, effective December 31, 2010 (see 75 FR 71033). Based on ambient air quality data for the years 2007-2009, a portion of Los Angeles County (excluding the high desert areas, San Clemente and Santa Catalina Islands) was identified as an area that did not meet the 2008 lead NAAQS. (2)

Areas are required to attain the revised lead standard as expeditiously as practicable, but no later than five years from the date the nonattainment designation became effective. For the Los Angeles County lead nonattainment area, this date is December 31, 2015.

Attainment demonstration state implementation plans (SIPs) are due 18 months after the effective date of an area's designation. For the Los Angeles County lead nonattainment area, the SIP was due June 30, 2012. These SIPs should include emissions inventories, a reasonable further progress (RFP) demonstration, a reasonably available control measures/reasonably available control technology (RACM/RACT) demonstration, an attainment demonstration, and contingency measures. Control measures for the 2008 lead NAAQS need to be in place as expeditiously as practicable. In order for control measures to result in three years of monitored clean data by the attainment date, lead areas required to demonstrate attainment by December 31, 2015 should have had all necessary controls in place no later than November 1, 2012. (3) South Coast Rule 1420.1, “Emissions Standard for Lead from Large Lead-Acid Battery Recycling Facilities,” was adopted by the South Coast Air Quality Management District (SCAQMD or “District”) on November 5, 2010.

The Lead Nonattainment Problem in Los Angeles County

Stationary sources of lead are generally large industrial sources, including metals processing, particularly primary and secondary lead smelters. Lead can also be emitted by iron and steel foundries; primary and secondary copper smelters; industrial, commercial and institutional boilers; waste incinerators; glass manufacturing; refineries; and cement manufacturing. The District determined that the primary causes of the nonattainment status of Los Angeles County are two large lead-acid battery recycling facilities, Exide Technologies located in the city of Vernon, and Quemetco, Inc. located in the City of Industry. These facilities receive used lead-acid batteries and other lead-bearing materials and recycle them, recovering the lead. Lead is recycled because of its value and to reduce toxic waste, and it is primarily used to manufacture new batteries.

Because regional ambient air lead concentrations indicate low ambient lead levels relative to the new lead NAAQS, and the only ambient levels exceeding the NAAQS were at sites near the lead-acid battery recyclers, SCAQMD's lead attainment strategy is focused on reducing directly-emitted lead from these two sources.

B. California's SIP Submittal and EPA Proposed Action

On December 11, 2013 (78 FR 75293), based on EPA's review of the Final 2012 Lead State Implementation Plan—Los Angeles County (May 2012) (“2012 Los Angeles County Lead SIP”) submitted by California, air quality monitoring data, and other relevant materials, EPA proposed to approve the State of California's attainment plan for the 2008 lead NAAQS, pursuant to CAA section 110(k)(3). The background for today's action is discussed in detail in EPA's December 11, 2013 proposed rulemaking and technical support document (TSD).

Our proposed approval of the attainment plan was based on EPA's finding that the area meets all lead NAAQS attainment plan requirements under CAA sections 172, 191, and 192. EPA's proposal to approve the State's attainment plan included SIP-approved control measures for secondary lead smelters. Implementation of these control measures has resulted in decreased emissions and the continued implementation of these control measures is expected to provide for attainment of the lead NAAQS by the applicable attainment date. EPA proposed to approve the attainment year emissions inventory submitted with the plan, as well as the RACM/RACT demonstration, the RFP demonstration, the attainment demonstration including modeling, and the contingency measures.

II. Public Comments and EPA's Response

We received one public comment on our proposed rule. We summarize the comment below and provide our response.

Comment: The commenter expressed concern over the closing of Doe Run in Missouri. (Doe Run was the last primary lead smelter in the United States, located in Herculaneum, Missouri, and ceased smelting operations at the end of December).

Response: Our proposed rule concerned lead nonattainment in the Los Angeles area. The facility referred to by the commenter is not the subject of our proposed action, and the comment has no relevance to our proposed action.

III. EPA's Final Action

For the reasons discussed in our December 11, 2013 proposal see 78 FR 75293), EPA is approving California's attainment SIP for the Los Angeles County lead nonattainment area for the 2008 lead NAAQS. This SIP submittal addresses CAA requirements and EPA regulations for expeditious attainment of the 2008 lead NAAQS for the Los Angeles County lead nonattainment area.

For the reasons discussed in our proposed rulemaking, EPA is proposing to approve under CAA section 110(k)(3) the following elements of the South Coast lead attainment SIP:

1. The SIP's base year emissions inventory as meeting the requirements of CAA section 172(c)(3) and 40 CFR 51.117(e)(1);

2. the attainment demonstration, including air quality modeling, that demonstrates attainment as expeditiously as practicable, as meeting the requirements of CAA section 172(c)(1);

3. the RACM/RACT demonstration, as meeting the requirements of CAA section 172(c)(1);

4. the RFP demonstration, as meeting the requirements of CAA section 172(c)(2);

5. and contingency measures, as meeting the requirements of the CAA section 172(c)(9).

VI. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve State choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves State law as meeting federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this action:

  • is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
  • does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
  • does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
  • does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and
  • does not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in theFederal Register. A major rule cannot take effect until 60 days after it is published in theFederal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
