Approval and Promulgation of Air Quality Implementation Plans; Maryland; Withdrawal of Proposed Rule

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Withdrawal of notice of proposed rulemaking.

SUMMARY:

On January 26, 1999 (64 FR 3906), EPA proposed to approve the State of Maryland's regulations for Nitrogen Oxides (NO_X) Budget Program (commonly referred to as the NO_X Budget Rule) as a revision to the State Implementation Plan (SIP). Prior to our taking any final rulemaking, Maryland informed us that it was revising the rule. On November 18, 1999, Maryland submitted a new SIP revision request to EPA which consists of the revised version of its NO_X Budget Rule. Because the State of Maryland has now submitted the revised version of its NO_X Budget Rule as a SIP revision, we are withdrawing our January 26, 1999 proposed rule on the old version. EPA will initiate a new and separate rulemaking on the Maryland's November 18, 1999 SIP revision submittal.

DATES:

This proposed rule is withdrawn as of June 16, 2000.
