N/A 

 B. A description of the event, including identification of the emissions source or sources associated with the startup or 

shutdown;

N/A 

 C. Whether any permit condition was exceeded and, if so, what 

permit condition was exceeded;

No.

 D. Whether the event was covered by any contingency plan for controlling emissions during startup and shutdown events and, if so, whether the plan was followed; if the plan was not followed, why not;

No.

 E. The duration of the event; N/A  F. The actions taken to minimize emissions during the event, including the use of any backup control systems;

N/A 

 G. Estimates or measurements, if any, of emissions during the event; if you did not have the ability to quantify emissions during the 

event, please explain why;

 H. Whether the emission profile of each unit was different during startup and shutdown than during normal operating conditions and, if so, how emissions were different and why; please provide any 

supporting information;

No.

during startup or shutdown? If so, please describe the event to which the standard would apply; the recommended standard (this could be an emission limitation, work practice, or operational standard) that would apply during the period; the basis for the recommended standard; why and how the standard would minimize emissions during the event; and how would compliance be determined and/or monitored.

PRESENCE OF AIR POLLUTANTS IN EMISSION POINTSPlease provide any existing emissions information and data covering hazardous air pollutants (HAP) and particulate matter (PM) for each listed process. Identify the appropriate box for which you are providing specific process information and/or pollutant emissions data.

Chromium Compounds and Hexavalent Chromium (including any Cr speciation data)Other metal HAP (As, Be, Cd, Co, Hg, Mn, Ni, Pb, Sb, Se)Hydrogen Fluoride (HF)Hydrogen Chloride (HCl)FormaldehydePhenolMethanolOther organic HAPThe existing data requested here has been provided to EPA by the industry’s trade association, the North 

American Insulation Manufacturers Association (“NAIMA”). The existing data provided by NAIMA was set forth in 

NAIMA’s May 5, 2010 letter to EPA. The existing emissions data provided from fiber glass companies included 

test results for the following pollutants: formaldehyde, methanol, phenol, particulate matter, hydrogen fluoride, 

metals (antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, manganese, nickel and selenium), 

mercury and hexavalent chromium. The existing emissions data provided from mineral wool companies included 

test results for the following pollutants: formaldehyde, methanol, phenol, particulate matter, carbon monoxide, carbonyl sulfide, hydrogen fluoride, metals (antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, 

manganese, nickel and selenium), mercury and hexavalent chromium. The scope of the existing data provided was the result of consensus reached by EPA, NAIMA and industry

representatives. In addition to the existing data submitted to EPA, extensive new emissions data is being collected from virtually all companies through the “BTEC, Inc. Quality Assurance Project Plan for the Mineral Wool and Wool Fiberglass Emissions Test Program.” This Test Program will collect and submit to EPA, through EPA’s Electronic Reporting Tool, representative emissions data for the following pollutants: formaldehyde, methanol, phenol, 

particulate matter, carbon monoxide, carbonyl sulfide, hydrogen fluoride, metals (antimony, arsenic, beryllium, 

cadmium, chromium, cobalt, lead, manganese, nickel and selenium), mercury and hexavalent chromium.
