Park: Advance Notice of Proposed Rulemaking; Extension of Public
Comment Period

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 document, 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.

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 document extending the public comment period for 30 days
(64 FR 42891). At the request of the Grand Canyon Trust, EPA is now
extending the public comment period for an additional 15 days.
DATES: The comment period on the advance notice of proposed rulemaking
is extended until September 30, 1999.
