Environmental Protection Agency July 22, 2008 – Federal Register Recent Federal Regulation Documents

EPA is issuing amendments to the national emission standards for hazardous air pollutants (NESHAP) for semiconductor manufacturing. These amendments establish a new maximum achievable control technology floor level of control for existing and new combined hazardous air pollutants process vent streams containing inorganic and organic hazardous air pollutants and clarify the emission requirements for process vents by adding definitions for organic, inorganic, and combined hazardous air pollutant process vent streams that contain both organic and inorganic hazardous air pollutant.

The Director of the Office of Ecosystem Protection, EPA-New England, is issuing a notice of availability of the draft National Pollutant Discharge Elimination System (NPDES) general permits for dewatering activity discharges to certain waters of the Commonwealth of Massachusetts and the State of New Hampshire. These General Permits replace the Construction Dewatering General Permits which expired on September 23, 2007. These draft General Permits establish Notice of Intent (NOI) requirements, effluent limitations, standards, prohibitions, and management practices for facilities with dewatering activity discharges from construction dewatering, flushing of potable water lines, pump testing of water wells, and dewatering of foundation sumps. Owners and/ or operators of facilities with dewatering discharges, including those currently authorized to discharge under the expired General Permits, will be required to submit an NOI to be covered by the General Permit to both EPA-New England and the appropriate state agency. After EPA and the State have reviewed the NOI, the facility will receive a written notification from EPA of permit coverage and authorization to discharge under the General Permit. The purpose of this document is to solicit public comments on the proposed General Permits. Public Comment Period: Interested persons may submit written comments on the draft General Permits to the EPA-Region I at the address listed below. Within the comment period, interested persons may also request, in writing, that EPA hold a public hearing pursuant to 40 CFR section 124.12, concerning the draft General Permits. Such requests shall state the nature of the issues proposed to be raised at the hearing. A public hearing may be held at least thirty days after public notice whenever the Regional Administrator finds that response to this notice indicates significant public interest. In reaching a final decision on this draft permit, the Regional Administrator will respond to all significant comments and make responses available to the public at EPA's Boston office. In addition to comments on the draft General Permit, EPA is also requesting comments on the cost associated with a limit for total residual chlorine (TRC) for discharges containing potable water. All comments and requests for public hearings must be postmarked or delivered before midnight August 21, 2008, the close of the public comment period. All public comments or requests for a public hearing must be submitted to the address below.

EPA, Region 2, is publishing a direct final Notice of Deletion of the Site, located in Cheektowaga, Erie County, New York, from the National Priorities List (NPL).
