          - 40 CFR Part 52
          - [EPA-R03-OAR-2009-0199; FRL-8963-7]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule; reopening of the comment period.

# SUMMARY:

                        EPA is reopening the comment period for a notice of proposed rulemaking (NPR) published on July 31, 2009 (74 FR 38161). In the NPR, EPA proposed to determine that the Baltimore, Maryland portion of the Hagerstown-Martinsburg nonattainment areas for the 1997 National Ambient Air Quality Standard (NAAQS) fine particulate (PM2.5) have clean data for the 1997 PM2.5                         NAAQS. EPA received comments from EarthJustice requesting that the 2009 monitored data referred to in the proposed rule be made available as part of the record and that the proposed rule either be revised or the comment period reopened to allow the public to consider the data. EPA is, therefore, reopening the comment period and including the data that was relied upon for the proposed clean data determination as well as the 2009 monitored data. The data relied upon by EPA is now provided in a Technical Support Document which is included in the record for this rulemaking. EPA is reopening the comment period through October 29, 2009. All comments received on or before October 29, 2009 will be entered into the public record and considered by EPA before taking final action on the proposed rule.                    

# DATES:

Written comments must be received on or before October 29, 2009.
