The Act affords EPA a 45-day period to review, and object as appropriate to, operating permits proposed by State permitting authorities. Section 505(b)(2) of the Act authorizes any person to petition the EPA Administrator within 60 days after the expiration of this review period to object to State operating permits if EPA has not done so. Petitions must be based only on objections to the permit that were raised with reasonable specificity during the public comment period provided by the State, unless the petitioner demonstrates that it was impracticable to raise these issues during the comment period or the grounds for the issues arose after this period.

The Louisiana Environmental Action Network submitted a petition requesting that the Administrator object to a title V operating permit issued by LDEQ to DuPont Dow Chemical Company, for the chloroprene unit at the DuPont Dow Elastomer's facility, in La Place, Louisiana.

The petitioner requested that the Administrator object to the DuPont Dow permit based on the following broad assertions:

1. LDEQ's interpretation of 40 Code of Federal Regulations (CFR) 63.115 is inconsistent with the Act's goal of protecting public health;

2. LDEQ's interpretation would result in increased discharges of halogenated organic hazardous air pollutants (HAP), an “extremely dangerous” class of pollutants;

3. LDEQ's interpretation results in greater controls of nonhalogenated vent streams relative to halogenated vent streams;

4. A rational interpretation of 40 CFR 63.115 must result in a Group 1 classification and the accompanying control requirements;

5. LDEQ has misinterpreted 40 CFR 63.115.

On November 20, 2003, the Administrator issued an order denying the petition. The order explains the reasons for the Administrator's decision.
