Notice is hereby given that, pursuant to 40 C.F.R. Part 51.161, and D.C. Official Code §2-505, the Air Quality Division (AQD) of the District Department of the Environment (DDOE), located at 1200 First Street NE, 5th Floor, Washington, DC, intends to issue Permit #6422-A1 and Permit #6423-A1 to the District of Columbia Water and Sewer Authority (DC Water) to amend and update the permit to construct and operate two (2) natural gas-fired steam boilers, issued on February 6, 2013.  The equipment which is described below is located at the Blue Plains Advanced Wastewater Treatment Plant at 5000 Overlook Avenue SW, Washington, DC.

The purpose of the permit amendment is to reduce the allowable heat input of the permitted boilers from 6.123 MMBTU/hr to 5.979 MMBTU/hr, to correspond with the actual heat input of the boilers that have been purchased and delivered to the facility for installation.  The reduced heat input to the boilers will result in modest emissions reductions from the previous estimates.  Other reasons for the amendment include the removal of redundant monitoring requirements and correction of a typographical error.

The application documentation, the permit amendment request letter, and the draft set of permits and supporting documents are available for public inspection at AQD and copies may be made available between the hours of 8:15 A.M. and 4:45 P.M. Monday through Friday.  Interested parties wishing to view these documents should provide their names, addresses, telephone numbers and affiliation, if any, to Stephen S. Ours at (202) 535-1747.

Interested persons may submit written comments or may request a hearing on this subject within 30 days of publication of this notice.  The written comments must also include the person’s name, telephone number, affiliation, if any, mailing address and a statement outlining the air quality issues in dispute and any facts underscoring those air quality issues.  All relevant comments will be considered in issuing the final permit.

Comments on the proposed permit and any request for a public hearing should be addressed to:
