# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Reopening of public comment period.

# SUMMARY:

On January 9, 2012, the EPA proposed amendments to three national emission standards for hazardous air pollutants: National Emission Standards for Hazardous Air Pollutant Emissions: Group IV Polymers and Resins; National Emission Standards for Hazardous Air Pollutants for Pesticide Active Ingredient Production; and National Emission Standards for Hazardous Air Pollutants for Polyether Polyols Production. The EPA is reopening the comment period until March 30, 2012. The EPA received a request for this reopening from the Sierra Club. The Sierra Club requested the reopening in order to analyze data and review the proposed amendments. EPA finds this request to be reasonable due to the multiple source categories involved in this action.
