10-3-00 - The EPA is making available "public comments" on the preliminary draft of its pending guidance on BACT for NOx Control on dry low NOx turbines on combined cycle units. They can be found at the following website: http://www.epa.gov/ttn/nsr/draft.html.

9-5-00 - 9/5/00 The EPA is making available for public review and comment the Information Collection Request (ICR) for Prevention of Significant Deterioration and Nonattainment New Source Review to the Office of Management and Budget.

A narrative explaining the adjustments requested to the NSR Year 2000 Information Collection Request and the Federal Register notice can be found at http://www.epa.gov/ttn/nsr/techinfo.html.

8-10-00 - The EPA is making available for public review and comment a preliminary draft of its pending guidance on BACT for NOx Control on dry low NOx turbines on combined cycle units. Several issues have been brought to EPA's attention as a result of recent controversies involving State permitting agencies, utilities, and turbine manufacturers over appropriate best available control technology (BACT) controls for NOx at natural gas combined cycle turbines for electric power generation. Selective Catalytic Reduction (SCR) has been considered BACT for limiting NOx emissions on many natural gas combined cycle turbines in attainment areas. These issues have to do with the impact of requiring selective catalytic reduction on dry low NOx natural gas combined cycle turbines for electric generations. The Notice of Availability for this draft guidance was signed by John Seitz on August 9, 2000 and will be published soon in the Federal Register. The EPA is taking comments on this draft guidance until 30 days after the Notice of Availability is published in the Federal Register. The EPA does not intend to respond to individual comments, but rather to consider comments and information from the public in the preparation of a final guidance document. It is important that the draft guidance being made available today for public review and comment does not represent official EPA policy or a formal position on the subject matter discussed and therefore is not to be relied on in interpreting EPA policy. The draft guidance document is found at http://www.epa.gov/ttn/nsr/draft.html.

8-9-00 - The EPA is making available for public review and comment a draft guidance, "Design of Flexible Air Permits" (White Paper Number 3). The Notice of Availability for this draft guidance was signed by John Seitz on August 7, 2000 and will be published soon in the Federal Register. The EPA is taking comments on this draft guidance until 30 days after the Notice of Availability is published in the Federal Register. The EPA does not intend to respond to individual comments, but rather to consider comments and information from the public in the preparation of a final guidance document. Click here for a PDF version of the Draft Guidance and click here for a PDF version of the Fact Sheet.

It is intended to help State and local permitting authorities design flexible permits for sources subject to title V of the Clean Air Act. It focuses on how these permitting authorities can design operating permits, within the scope of title V of the Clean Air Act and the operating permits regulations. This draft guidance provides sources with the flexibility to more quickly change to different modes of operation, as the nature of their business requires, without being unnecessarily impeded by the terms of their operating permit. This draft guidance would also advance the Agency's goals of encouraging pollution prevention, assuring adequate public participation, promoting equal or better environmental protection, and facilitating opportunities for sources to comply in a smarter, more efficient fashion.

6-29-00 - The EPA is making available for public review and comment a preliminary draft of its pending guidance for States who choose to use emissions reductions from motor vehicles operated on low sulfur gasoline as new source review offsets. Offsets are one prerequisite for major stationary sources or major modifications seeking permit approval in nonattainment areas. On February 10, 2000, EPA issued new rules containing emissions standards ("Tier 2 standards") for all passenger vehicles, including sport utility vehicles, minivans, vans and pickup trucks. To ensure the effectiveness of low emission control technologies in these vehicles, EPA's new rules also set standards to significantly reduce the sulfur content in gasoline. To assist refineries and States who may otherwise have difficulty acquiring emissions reductions to offset proposed emissions increases at affected refineries, EPA intends to provide Federal guidance on the use of Tier 2 emissions reductions as NSR offsets. The EPA does not intend to respond to individual comments, but rather to consider comments and information from the public in the preparation of a final guidance document. The draft guidance document is found at http://www.epa.gov/ttn/nsr/rule_dev.html.

5-25-00 - A letter dated May 23, 2000 with enclosure to Henry Nickel from Region V per an applicability determination for the replacement and reconfiguration of steam turbines at Detroit Edision's Monroe Power Plant had been added to the Uncategorized Policy and Guidance Documents section.

4-12-00 - Testimony of John Seitz, Office Director of OAQPS before the Subcommittee on clean air, wetlands, private property, and nuclear safety, February 28, 2000.

3-20-00 - The EPA is making available for public review and comment a preliminary draft of its pending guidance on BACT and LAER for Tier 2/gasoline sulfur refinery projects. On February 10, 2000, EPA issued new emissions standards ("Tier 2 standards") for all passenger vehicles, including sport utility vehicles, minivans, vans and pickup trucks. To ensure the effectiveness of low emission control technologies in these vehicles, this rule also sets new standards to significantly reduce the sulfur content in gasoline. To provide greater certainty and to expedite the NSR permitting process for refinery projects undertaken to comply with the recently issued gasoline sulfur standards, EPA intends to provide Federal guidance on BACT and LAER for these type of projects. The EPA does not intend to respond to individual comments, but rather to consider comments and information from the public in the preparation of a final guidance document. The draft guidance document is found at http://www.epa.gov/ttn/nsr/rule_dev.html.

8-9-99 - An Order was signed by the Administrator on June 16, 1999 denying a Petition from Kawaihae Cogeneration Partners (KCP) requesting EPA to object to a PSD/Covered Source permit issued to Maui Electric Company (MECO) for the construction and operation of two 20 megawatt combustion turbines to be located at MECO's Maalaea Generating Station. The permit was issued by the Hawaii Department of Health (DOH) and constituted both a construction permit issued pursuant to the PSD regulations (delegated to DOH in 1983) and a state operating permit issued pursuant to Title V. KCP petitioned EPA to object to the permit on the grounds that the project had not applied BACT for the control of NOx and SO2 emissions. EPA denied the Petition because the appeal was based on PSD issues and only the Environmental Appeals Board has the authority to review the merits of a federal PSD permit. The file is available in either a Word Perfect format or a PDF version.
