State air permit modifications approved for proposed cement plant near Wilmington

RALEIGH – The N.C. Division of Air Quality has issued a revised air quality permit for a proposed cement manufacturing plant in New Hanover County.

The revised permit allows Titan America/Carolinas Cement Co. more time to begin construction on the Portland cement manufacturing facility it plans to operate at 6411 Ideal Cement Road in Castle Hayne. The revisions also bring the facility’s air permit limits into accordance with new requirements set by the U.S. Environmental Protection Agency, or EPA.

The Division of Air Quality initially issued an air permit for the proposed cement plant in February 2012, but the permit was set to expire at the end of August 2013 if Titan had not yet begun construction of the facility. Titan has not begun construction. The permit revisions issued Thursday extend Titan’s authorization to construct for an additional 18 months.

The revised permit also changes the facility’s limits for particulate emissions in light of recent changes in methods that the EPA allows cement plant operators to use in calculating their emissions. The plant would not actually be changing its emissions controls, but the EPA changed the averaging time for calculating emissions, which results in a higher limit for annual emissions. Under the permit, Titan’s emissions limits are increased by 22 tons/year for fine particles (PM 2.5) and by 10 tons/year for coarse particles (PM 10).

The division held a public hearing on the revised permit on Aug. 5 at the University of North Carolina at Wilmington and accepted written comments until Aug. 9.
