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.
