**SUPPLEMENTARY INFORMATION :**  This proposal addresses the following local rules: SCAQMD Rule 1155, Particulate Matter (PM) Control Devices and SMAQMD Rule 421 Mandatory Episodic Curtailment of Wood and Other Solid Fuel Burning (except section 402). In the Rules and Regulations section of this Federal Register , we are approving these local rules in a direct final action without prior proposal because we believe these SIP revisions are not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule. Please note that if we receive adverse comment on an amendment, paragraph, or section of these rules and if that provision may be severed from the remainder of the rules, we may adopt as final those provisions of the rules that are not the subject of an adverse comment.

We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action.

Dated: January 23, 2015. Jared Blumenfeld, Regional Administrator, Region IX.

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule; extension of comment period.

**SUMMARY :**  EPA issued a proposed rule in the Federal Register January 21, 2015, concerning long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances and perfluoroalkyl sulfonate (PFAS) chemical substances. This document extends the comment period for 90 days, from March 23, 2015, to June 26, 2015. The comment period is being extended because EPA received several comments asserting that there may be significant implications for the supply chain and it is critical that interested stakeholders have sufficient time to respond to the proposed rulemaking.

**DATES :**  The comment period for the proposed rule published on January 21, 2015 (80 FR 2885) is extended. Comments, identified by docket identification (ID) number EPA–HQ– OPPT–2013–0225, must be received on or before June 26, 2015.

**ADDRESSES :**  Follow the detailed instructions provided under **ADDRESSES** in the Federal Register document of January 21, 2015 (80 FR 2885) (FRL– 9915–63).

**SUPPLEMENTARY INFORMATION :**  This document extends the public comment period established in the Federal Register proposed rule of January 21, 2015. This proposed rule for LCPFAC chemical substances is proposing to designate as a significant new use manufacturing (including importing) or processing of an identified subset of LCPFAC chemical substances for any use that will not be ongoing after December 31, 2015, and all other LCPFAC chemicals substances for which there are currently no ongoing uses. For this SNUR, EPA is also proposing to make inapplicable the exemption for persons who import LCPFAC chemical substances as part of articles. In addition, EPA is also proposing to amend a SNUR for PFAS chemical substances that would make inapplicable the exemption for persons who import PFAS chemical substances as part of carpets. EPA is hereby extending the comment period, which was set to end on March 23, 2015, to June 26, 2015.

To submit comments, or access the docket, please follow the detailed instructions provided under **ADDRESSES** in the Federal Register document of January 21, 2015. If you have questions, consult the technical person listed under **FOR FURTHER INFORMATION CONTACT**
