1. Title of of the Regulations:

Amendment to Regulation No. 1124 Control of Volatile Organic Compounds Emissions

2. 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.

Automated parts handling systems include, but are not limited to, hoists and conveyors.

???Batch Vapor Cleaning Machine??? means a vapor solvent cleaning machine in which individual parts or a set of parts move through the entire cleaning or drying cycle before new parts are introduced into the cleaning machine. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

???Carbon Adsorber??? means a bed of activated carbon into which an air/solvent gas-vapor stream is routed and which adsorbs the solvent on the carbon.

???Cold Cleaning Machine??? means a solvent cleaning machine that contains and/or uses unheated liquid solvent into which parts are placed to remove soils from the surfaces of the parts or to dry the parts. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

???Downtime Mode??? means the time period when a solvent cleaning machine is not cleaning or drying parts and the sump heating coils, if present, are turned off.

???Dwell??? means the technique of holding parts within the freeboard area but above the vapor zone of a solvent cleaning machine. Dwell occurs after cleaning or drying to allow solvent to drain from the parts or parts baskets back into the solvent cleaning machine.

???Dwell Time??? means the period of time between when parts or a parts basket is placed in the vapor zone of a batch vapor or in-line vapor cleaning machine and when solvent dripping ceases.

???Freeboard Height??? means, for a batch cold cleaning machine, the distance from the liquid solvent level to the top of the solvent cleaning machine. For a batch vapor cleaning machine, it is the distance from the solvent/air interface to the top of the solvent cleaning machine, as measured during idling mode. For an in-line cleaning machine, it is the distance from the solvent/air interface to the bottom of the entrance or exit opening, whichever is lower, as measured during idling mode.

???Freeboard Ratio??? means the ratio of the solvent cleaning machine freeboard height to the smaller interior dimension (length, width, or diameter) of the solvent cleaning machine.

???Freeboard Refrigeration Device??? means a set of secondary coils mounted in the freeboard area that carries a refrigerant or other chilled substance to provide a chilled air blanket above the solvent vapor. A primary condenser that is capable of maintaining a temperature, in oF, in the center of the chilled air blanket at not more than 30 percent of the solvent???s boiling point is both a primary condenser and a freeboard refrigeration device.

???Idling Mode??? means the time period when a solvent cleaning machine is not actively cleaning or drying parts and the sump heating coils, if present, are turned on.

???Immersion Cold Cleaning Machine??? means a cold solvent cleaning machine in which the parts are immersed in the solvent when being cleaned or dried. A remote reservoir cold cleaning machine that is also an immersion cold cleaning machine is considered an immersion cold cleaning machine for purposes of this Section.

???In-line Vapor Cleaning Machine??? means a vapor solvent cleaning machine that uses an automated parts handling system, typically a conveyor, to automatically provide a continuous supply of parts to be cleaned or dried. These units are fully enclosed except for the conveyor inlet and exit portals.

???Primary Condenser??? means a series of circumferential cooling coils on a vapor cleaning machine through which a chilled substance is circulated or recirculated to provide continuous condensation of rising solvent vapors and, thereby, creating a concentrated solvent vapor zone.

???Reduced Room Draft??? means decreasing the flow or movement of air across the top of the freeboard area of a solvent cleaning machine to less than 15.2 meters per minute (50 feet per minute) by methods including, but not limited to, redirecting fans and/or air vents to not blow across the cleaning machine, moving the cleaning machine to a corner where there is less room draft, and constructing a partial or complete enclosure around the cleaning machine.

???Remote Reservoir Cold Cleaning Machine??? means a solvent cleaning machine in which liquid solvent is pumped to a sink-like work area that immediately drains solvent back into an enclosed container while parts are being cleaned or dried, allowing no solvent to pool in the work area.

???Soils??? means contaminants that are removed from the parts being cleaned. Soils include, but are not limited to, grease, oils, waxes, metal chips, carbon deposits, fluxes, and tars.

???Solvent/air Interface??? means, for a vapor cleaning machine, the location of contact between the concentrated solvent vapor layer and the air. This location of contact is defined as the mid-line height of the primary condenser coils. For a cold cleaning machine, it is the location of contact between the liquid solvent and the air.

???Solvent Cleaning Machine??? means any device or piece of equipment that uses volatile organic compounds, liquid or vapor, to remove soils from parts or to dry parts. Types of solvent cleaning machines include, but are not limited to, batch vapor, in-line vapor, in-line cold, immersion cold, and remote reservoir cold cleaning machines, as well as, airless cleaning and airtight cleaning systems.

???Superheated Vapor System??? means a system that heats the solvent vapor, either passively or actively, to a temperature 10oF above the solvent???s boiling point. Parts are held in the superheated vapor before exiting the machine to evaporate the liquid solvent on the parts. Hot vapor recycle is an example of a superheated vapor system.

???Vapor Cleaning Machine??? means a batch or in-line solvent cleaning machine that heats liquid solvent that is used as part of the cleaning or drying cycle. The heated solvent may or may not be boiling. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

???Vapor Up Control Switch??? means a thermostatically controlled switch that shuts off or prevents solvent from being sprayed when there is no vapor. On in-line vapor cleaning machines the switch also prevents the conveyor from operating when there is no vapor.

???Working Mode??? means the time period when the solvent cleaning machine is actively cleaning or drying parts.

???Working Mode Cover??? means any cover or solvent cleaning machine design that allows the cover to shield the cleaning machine openings from outside air disturbances while parts are being cleaned or dried in the cleaning machine. A cover that is used during the working mode is opened only during parts entry and removal.
