organic liquids distribution (non-gasoline) mact summary

3. What processes and operations at affected facilities are included in this source category?

This source category involves the distribution of organic liquids into, out of, or within a plant site. Emission sources controlled by this rule include storage tanks, transfer operations, transport vehicles while being loaded, and equipment leak components (valves, pumps, and sampling connections) that have the potential to leak. The types of organic liquids and emission sources covered by this rule are frequently found at many types of facilities that are already subject to other NESHAP. If an emission source is in organic liquid distribution service and is already subject to an existing 40 CFR part 63 NESHAP, then that emission source is not subject to this rule.

Organic liquids are defined as those non-crude oil liquids that contain at least five percent by weight of any combination of the HAPs listed in Table 1 to Subpart EEEE of Part 63, and have a total liquid vapor pressure of 0.7 kilopascals [0.1 pound per square inch absolute (psia)] or greater, and all crude oils downstream of the first point of custody transfer.

For the purposes of the rule, organic liquids do not include gasoline, fuels that are consumed or dispensed on the plant site, kerosene (No. 1 distillate oil), diesel (No. 2 distillate oil), asphalt, and heavier distillate oils and fuel oils, hazardous waste, wastewater, or ballast water.
