National Emissions Standards for Hazardous Air Pollutants: 
Mineral Wool Production and Wool Fiberglass Manufacturing

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; Notice of extension of public comment period.

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

SUMMARY: The EPA published in the Federal Register on November 25, 
2011, the proposed rules, ``National Emission Standards for Hazardous 
Air Pollutants: Mineral Wool Production and Wool Fiberglass 
Manufacturing.'' The EPA was asked to hold a public hearing only on the 
wool fiberglass manufacturing proposed rule, and on December 20, 2011, 
published a notice announcing the hearing and extending the comment 
period for only the wool fiberglass manufacturing proposed rule (76 FR 
78872). The comment period for the mineral wool production proposed 
rule was not extended because no public hearing was requested and no 
requests

[[Page 3224]]

for an extension of the comment period were received. It has come to 
our attention that confusion arose from the result of having two 
different comment periods for the two proposed rules in the same 
action. Therefore, the EPA is extending the public comment period for 
the mineral wool production proposed rule for 10 days from January 24, 
2012 to February 3, 2012, so that comments on both rules in this action 
are due on the same date.

DATES: Comments must be received by February 3, 2012.

2011, proposed rule should be addressed to Susan Fairchild, Office of
