Comment Period and Public Hearings Announced for Proposed Log Fumigation Rule

Raleigh

The public is invited to comment on the proposed air quality rule changes to regulate emissions of methyl bromide at log fumigation operations. The Division of Air Quality (DAQ) will also host public hearings on the proposed rules in Raleigh, on July 22, and Wilmington, on July 23.

DAQ proposed regulating methyl bromide by establishing an Acceptable Ambient Level (AAL) because the lack of specific federal or state regulatory measures for the use of this hazardous air pollutant creates a potential public health risk.  Neurological and respiratory effects are of greatest concern from exposure to methyl bromide, which is an odorless, colorless gas. The recent increase in businesses interested in using methyl bromide for log fumigation in North Carolina prompted DAQ to take this action.

The proposed rule establishes emission control requirements for hazardous air pollutants and toxic air pollutants from log fumigation operations.  A proposed amendment adds methyl bromide to the toxic air pollutant list with an AAL value of 0.005mg/m3 (milligrams per cubic meter) with a 24-hour averaging time. The Environmental Management Commission is also requesting public comment on a range for the AAL from 0.005 mg/m3 to 0.078 mg/m3.
