    TO: Urban Strategy Docket

    FROM: Barbara Driscoll

    DATE: May 26, 1999

    SUBJECT: Description of New Source Categories That are Listed for FutureRegulatory Development

    This memo was developed to define the new source categories that are listed for

    future regulatory development in the Urban Area Toxics program. The new source

    categories listed for regulation are divided into two groups:

    C Source categories whose emission estimates were derived from the ToxicRelease Inventory (TRI) database. These source categories are designated byspecific SIC codes, therefore the source category definitions parallel the SICcode definitions. These categories include:

    - Cyclic crude and intermediate production- Industrial inorganic chemical manufacturing- Industrial organic chemical manufacturing- Plastic materials and resins manufacturing- Synthetic rubber manufacturing

    C Source categories whose emission estimates were derived from data provided

    by the EPAs Emission Standards Division (ESD). The definitions for thesesource categories were obtained from Federal Register preambles forproposed and promulgated rules, Background Information Documents, or fromthe data provided by ESD engineers and scientists. These categories include:

    - Flexible polyurethane foam fabrication operations - Gasoline Distribution Stage I

    - Hospital sterilizers- Mercury cell chlor-alkali plants- Municipal landfills- Oil and natural gas production

  • 2

    - Paint strippers- Publicly owned treatment works

    The source categories discussed below cover only area sources. Section 112 of the Clean Air

    Act defines an area source as any stationary emission source or group of stationary sources located

    within a contiguous area and under common control that emits or has the potential to emit, considering

    controls in the aggregate, less than 10 tons per year of any of the 188 regulated hazardous air pollutant

    and less than 25 tons per year of any combination of hazardous air pollutants.

    The definitions for the source categories derived from the TRI information have many specific

    products listed here. This does not mean that EPA will regulate all of these sources. These are draft

    definitions are only a beginning point, and a separate description will be developed during the regulatory


    1.0 Source Categories derived from TRI

    It should be noted that in the section 112(k) emissions inventory, adjustments were made in the

    emission estimates for many source categories because they overlapped with one another. Thus, the

    source categories described below have already been adjusted for any potential overlap with other

    source categories, including MACT source categories. For more information, see the 112(k) Inventory

    Report appendices B and D.

    1.1 Cyclic Crude and Intermediate Production

    This source category is designated by the SIC Code 2865: Cyclic Organic Crudes and

    Intermediates, and Organic Dyes. General product of this industry include:

    C Aromatic chemicals, such as benzene, toluene, mixed xylenes, and naphthalene;

    C Synthetic organic dyes, and
