RULE 1141.2. SURFACTANT MANUFACTURING

(a) Definitions

For the purpose of this rule the following definitions shall apply:

  1. REACTIVE ORGANIC GASES (ROG) means any gaseous compound which contains the element carbon; excluding carbon monoxide, carbon dioxide, carbonic acid, carbonates and metallic carbides; and excluding methane, 1,1,1-trichloroethane, methylene chloride, trifluoromethane and chlorinated-fluorinated hydrocarbons.
  2. A SURFACTANT is a surface-active agent, which is any compound that reduces surface tension or interfacial tension, when in solution. Surfactants are divided into three categories: detergents, wetting agents, and emulsifiers.
  3. A SURFACTANT MANUFACTURER is a person who produces a synthetic surfactant, most commonly by reacting an organic compound with a sulfonating or sulfating compound.
  4. A VENT is a port or opening whose function is to allow gases to discharge to the atmosphere when leaving a reactor or other equipment.
  5. A SURFACTANT REACTOR is any equipment is which organic and/or other materials are reacted to produce a surfactant; this may include stripping columns, condensers, and water separators.
  6. A CONDENSER is a jacketed tube which has a cooling fluid, often water, flowing through the jacket and which cools and liquefies gases flowing through the inside of the tube.
  7. A DEGASSER is any piece of equipment which removes dissolved gases from liquids.
  8. A NEUTRALIZER is any piece of equipment in which materials are added to a liquid in order to change the acidity or alkalinity of the liquid.
  9. A STRIPPER is any piece of equipment which removes a material from a mixture of materials.
  10. A MINERALIZER is any piece of equipment in which minerals or chemicals, such as lime or iodine, are suspended in a surfactant.
  11. SURFACTANT MANUFACTURING EQUIPMENT includes any or all of the following equipment: surfactant reactors, process condensers, degassers, neutralizers, strippers, and mineralizers.

(b) Requirements

After July 1, 1986 a surfactant manufacturer shall not produce surfactants unless:

  1. the total emissions of reactive organic gases (ROG) from the surfactant manufacturing equipment, before being vented to the atmosphere, are reduced:

    (A) to 0.5 pound per 1000 pounds of surfactant produced, or

    (B) by 95 percent (wt) or more; and

  2. all ports used for inspection, taking samples, or adding ingredients are closed when not in use.

(c) Compliance

  1. A surfactant manufacturer shall:

    (A) On or before January 1, 1985, submit for District approval, a Compliance Plan describing the methods and equipment to be used to achieve compliance with subsection (b)(1)(A) or (b)(1)(B), and

    (B) On or before July 1, 1986, submit applications for new permits to construct or operate, as necessary, for new or modified equipment involved in such methods.

  2. On or after July 1, 1986, a surfactant manufacturer shall operate under the approved conditions specified in the Compliance Plan for compliance with subsection (b)(1), and/or under conditions included in permits to construct or operate issued for applications submitted pursuant to subsection (c)(1)(B).

(d) Exemptions

The provisions of this rule shall not apply to:

  1. Soap manufacturing operations,
  2. Facilities that only blend and package surfactants,
  3. Equipment that uses exclusively organic materials which have a vapor pressure less than 5 mm of Hg at 20o, and
  4. Facilities that emit less than 5 pounds of ROG from surfactant manufacturing equipment in each and every day.

(e) Fees

For the purpose of determining the appropriate processing fees only, the filing of a Compliance Plan(s) as provided in subsection (c)(1) shall be considered the equivalent of filing an application for a permit. The person submitting the Plan shall be assessed a filing and an evaluation fee as described in Rules 301 and 301.1.
