Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of availability and solicitation of public comment.

SUMMARY:

EPA has developed a draft National Action Plan to promote further voluntary reductions of use and exposure to alkyl-lead compounds. Alkyl-lead is used as a fuel additive to reduce “knock” in combustion engines and also to help lubricate internal engine components and protect intake and exhaust valves against recession. Currently, the largest uses of alkyl-lead are in aviation gasoline for general aviation (piston-engine) aircraft and racing gasoline. This plan was developed pursuant to the Agency's Multimedia Strategy for Priority Persistent, Bioaccumulative, and Toxic (PBT) Pollutants. This Notice announces the availability of the Alkyl-lead National Action Plan for public review and comment.

DATES:

Comments, identified by docket control number OPPTS-00672, must be received on or before September 25, 2000.

ADDRESSES:

Comments may be submitted by mail, electronically, or in person. Please follow the detailed instructions for each method as provided in Unit I. of the SUPPLEMENTARY INFORMATION. To ensure proper receipt by EPA, it is imperative that you identify docket control number OPPTS-00672 in the subject line on the first page of your response.

II. What Action is the Agency Taking?

On November 16, 1998, EPA released its Agency-wide Multimedia Strategy for Priority Persistent, Bioaccumulative, and Toxic (PBT) Pollutants (PBT Strategy). The goal of the PBT Strategy is to identify and reduce risks to human health and the environment from current and future exposure to priority PBT pollutants. This document serves as the Draft National Action Plan for Alkyl-Lead, one of the 12 Level 1 priority PBT pollutants identified for the initial focus of action in the PBT Strategy.

Alkyl-lead compounds are man-made compounds in which a carbon atom of one or more organic molecules is bound to a lead atom. Tetraethyllead (TML) and TML compounds are the most common alkyl-lead compounds that have been used in the past and are still in use today in the United States. These two alkyl-lead compounds are the focus of this National Action Plan. Alkyl-lead is used as a fuel additive to reduce “knock” in combustion engines and also to help lubricate internal engine components and protect intake and exhaust valves against recession. Currently, the largest uses of alkyl-lead are in aviation gasoline for general aviation (piston-engine) aircraft, and racing gasoline. Neither of these uses are subject to any of the regulations that restrict leaded motor gasoline use.

In the body, alkyl-lead compounds are distributed through the blood to “soft tissues” particularly the liver, kidneys, muscles, and brain. Initial symptoms of alkyl-lead poisoning include, among others: anorexia, insomnia, tremor, weakness, fatigue, nausea and vomiting, mood shifts such as aggression or depression, and impairment of memory. In the case of acute alkyl-lead poisoning, possible health effects include mania, convulsions, delirium, fever, coma, and in some cases even death. Lead poisoning due to the Start Printed Page 51825ingestion or inhalation of inorganic lead compounds emitted as exhaust through the combustion process (as a direct result of the use of alkyl-lead in gasoline) is a widely recognized public health problem.

EPA is requesting public comment on a strategy to address the remaining risks to human health and the environment from exposure to alkyl-lead: (1) Contribute to international efforts to reduce the use of alkyl-lead world-wide; (2) pursue voluntary initiatives to reduce the use of alkyl-lead in aircraft gasoline, race cars, and non-road vehicles such as farm machinery, marine vessels, construction equipment, and recreational vehicles; and (3) collect information as possible, given resource constraints, related to production, use, emissions, and continued exposure scenarios.
