I. Introduction

M eeting s with representatives of the North American Insulation Ma nufacturer’s Association (NAIMA) and the wool fiberglass manufacturing and mineral wool production industries was held at the U.S. Environmental Protection Agency (EPA) facility in Research Triangle Park, NC , on December 13 , 201 1 . The meeting s w ere reques ted by NAIMA to present their questions and clarifications related to the recent proposal for w ool fiberglass (subpart NNN) and mineral wool (subpart DDD)

. This memorandum summarizes the major topics discussed during the meeting

. II. Attendees

See Attachmen t 1 (mineral wool) and Attachment 2 (wool fiberglass).

III. Discussion

Mineral Wool Production Ms. Fairchild conducted introductions of everyone and Mr. Crane provided handouts of “The NAIMA Mineral Wool Industry Presentation to EPA” which is included as Attachment 3. Th e following bullets summarize discussion topics and comments made during the meeting :

• 6 of the 7 mineral wool companies are small businesses

. • Raw materials could be a source of HF and H Cl emissions; rock does have Cl.

• HF and HCl were not on industry’s “radar screen” before; therefore, they do not have any historical data

• It is problematic to switch over to natural rock for several technical and logistical
reasons , including proximity to main raw material suppliers.

• Some operating permits s pecify that raw materials cannot be changed.

.2 • Caustic sorbents are needed to reduce SO2

. • Greater energy would be needed to melt some rock; requiring more coke (fuel) and would likely result in higher secondary emissions

. • Recycled (slag) content is a major marketing issue for the mineral wool industry.

• Industry requests alternate limits since any add

- on control equipment such as dry or wet scru bbers would be cost prohibitive

. • Some of the curing/collection emission limits look like incorrect test data was u sed.

• Requested clarification on the performance test requirement for any raw material change greater than 10%.

• Startup/shutdown provisions are problematic. There is no historical test data related to startups or shutdowns. Some shutdowns only last 30 min utes and the compliance testing involves three 1

- hour test runs.

Wool Fiberglass Manufacturing Ms. Fairchild conducted introductions of everyone and Mr. Crane provided handouts of “The NAIMA Wool Fiberglass Industry Presentation to EPA” which is include d as Attachment 4. Th e following bullets summarize discussion topics and comments made during the meeting:

• Majority of companies and facilities have switched to non

- formaldehyde binders.

• The hexavalent chrome issue is related to one facility; new test in g results showed 11.91 pounds per year of hexavalent chrome emissions; additional testing being done on the other furnace at the facility.

• Industry recommending subcategorization for glass

- melting furnaces.

• Industry has conducted their own risk analysis us ing 25 pounds of hexavalent chromium to demonstrate cancer risk below 1

- in

- 1 million

. • Industry asked why the proposed rule changed the required test method from method 316 to method 318

. • Low

- density products require a lot of natural gas to melt the glass.

• Industry asked if any of the test results from non

- bonded lines were used in the MACT floor analyses

. • Wet scrubber technology may not be a viable control if the inlet concentrations are very low; also need to consider secondary impacts
