4 FACILITY DESCRIPTION: Permit Action 001 (Total Facility Permit) The Order of St. Benedict/St. John s Abbey, Saint John s University (SJU) is a higher education facility in Collegeville, Minnesota. SJU currently has six boilers, two electrical generators, and a few other small emission units. The different boilers fire either coal or natural gas with fuel oil backup. In late 1997, a boiler that fired a mixture of wood waste and campus waste was shut down and removed from site. SJU submitted a minor amendment application, dated December 1998, for the installation of a new 50.4 MMBtu/hr boiler at the facility. MPCA staff reviewed the application (in a letter dated March 17, 1999, from Peggy Bartz to Dan Webber) and concluded that the modification did not qualify as a minor amendment. SJU submitted a new application, dated April 1999, for a major amendment. This modification will be rolled into the Title V application (dated February 12, 1996) and both applications will be issued under a combined Title V - total facility and construction permit. Permit Action 002 (Minor Amendment) This permit action is for the installation of two emergency generators, EU 014 Emergency Generator #1 and EU 015 Emergency Generator #2. Dispersion modeling and notification requirements that have been completed were deleted from Table B. General performance test requirements were deleted from Table B and a general performance test requirement was added to the Total Facility section. Performance test requirements were also updated for EU004 Boiler #4 and EU0013 Boiler #6. This minor amendment application was received on July 11, 2005.
