Title of of the Regulations:
Amendment to Regulation No. 1124 Control of Volatile Organic Compounds Emissions
Brief Synopsis of the Subject, Substance and Issues:
Regulation 1124 establishes emission standards for sources emitting volatile organic compounds (VOCs). VOC emissions are precursors to the formation of ozone and Delaware does not meet the federal air quality standards for ozone. This amendment proposes to add a new section, Section 46, to control the emissions of VOCs from lightering operations that occur in the waters of the State. Lightering is the process where the draft of large ocean going vessels is reduced by bulk transfer of cargo (usually crude oil) from the ocean going vessels to smaller service vessels. This reduction in draft is necessary for the ocean going vessel to be able to proceed upriver. In 2002, more than 1,836 tons of VOCs were emitted during lightering operations. Lightering operations represented the largest stationary VOC emission source in Delaware.
Some of the VOCs emitted during lightering operations are also classified as hazardous air pollutants (HAPs). It was estimated that in 2002 nearly 200 tons of HAPs were emitted during lightering operations. These HAPs include benzene, toluene, xylenes, ethyl benzene and various polycyclic aromatic hydrocarbons (PAHs). Benzene is a known human carcinogen and benzo(a)pyrene, a PAH, has been classed as a probable human carcinogen. Exposure to the other HAPs can have a non-cancer impact on the public health, safety and welfare. The emissions of these HAPs will also be reduced under this amendment.
