# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Extension of public comment period.

# SUMMARY:

On February 17, 2011, EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants for Primary Lead Smelting (76 FR 9410). The EPA is extending the deadline for written comments on the proposed amendments by 19 days to May 8, 2011. The EPA received a request for this extension from the Doe Run Company, the sole covered facility. Doe Run Company requested the extension in order to analyze data and review the proposed amendments. EPA finds this request to be reasonable due to the significant changes the proposal would make to the current rule.
