Assessment of Visibility Impairment at the Grand Canyon National Park:

Advance Notice of Proposed Rulemaking; Extension of Public Comment Period

AGENCY: Environmental Protection Agency.

ACTION: Advance notice of proposed rulemaking; extension of public comment period.

SUMMARY: The Environmental Protection Agency (EPA) is extending the comment period for an advance notice of proposed rulemaking, published June 17, 1999 (64 FR 32458), regarding visibility impairment at the Grand Canyon National Park (GCNP) and the possibility that the Mohave Generating Station (MGS) in Laughlin, Nevada may contribute to that impairment. In the June 17 notice, EPA requests information that it should consider in determining whether visibility problems at the GCNP can be reasonably attributed to MGS, and if so, what, if any, pollution control requirements should be applied.

The public comment period for the advance notice of proposed rulemaking was originally due to expire on August 16, 1999. On August 6, 1999, at the request of Southern California Edison Company, EPA published a notice extending the public comment period for 30 days (64 FR 42891). On September 14, 1999, at the request of the Grand Canyon Trust, EPA published a notice extending the public comment period for an additional 15 days (64 FR 49756). At the request of both Southern California Edison and the Grand Canyon Trust, EPA is now extending the public comment period for an additional 21 days.

DATES: The comment period on the advance notice of proposed rulemaking is extended until October 21, 1999.

ADDRESSES: Comments should be submitted (in duplicate, if possible) to: EPA Region IX, 75 Hawthorne Street (AIR2), San Francisco, CA 94105, Attn: Regina Spindler.
