LAST REVISED 08/20/91
                              
                              REGULATION 3 - SECTION 2



         RULE 2-100 - TITLE


                   AIRBORNE TOXIC CONTROL MEASURE FOR
                HEXAVALENT CHROMIUM EMISSIONS FROM CHROME
              PLATING AND CHROMIC ACID ANODIZING OPERATIONS


          This regulation is adopted pursuant to the provisions of Section
          93102, Titles 17 and 26, California Code of Regulations (CCR).

                                                   [Adopted August 20,1991]

          RULE 2-110 - PURPOSE

          On January 23, 1986, pursuant to Section 39662 of the Health and
          Safety Code, The Air Resources Board (ARB) identified hexavalent
          chromium as a toxic air contaminant for which there is not
          sufficient available scientific evidence to support
          identification of a threshold exposure level below which no
          significant adverse health effects are anticipated (see Title 17,
          California Code of Regulations, Section 93000). This airborne
          toxic control measure will reduce hexavalent chromium emissions
          from chrome plating and chromic acid anodizing operations and
          resulting cancer risk and cancer incidence to the lowest level
          achievable through application of best available control
          technology at operations subject to this measure.

          RULE 2-120 - APPLICABILITY

          This regulation shall apply to any decorative or hard chrome
          plating facilities, or to any chromic acid anodizing facilities,
          which are in operation at the time this measure is adopted, or
          begin operation at any time after this measure is adopted

          RULE 2-130 - DEFINITIONS

          (a)  AMPERE-HOURS:

          The integral of electrical current applied to a plating tank
          (amperes) over a period of time (hours).

          (b)  ANTI-MIST ADDITIVE:

          A chemical which reduces the emission rate from the tank when
          added to and maintained in the plating tank.

          (c)  CHROME:

             Metallic chrome.

          (d)  CHROME PLATING:

             Either hard or decorative plating.

          An aqueous solution of chromium trioxide (CrO3), or a commercial
          solution containing chromic acid, dichromic acid (H2CrO7), or
          trichromic acid (H2Cr3O10).

          (f)  CHROMIC ACID ANODIZING:

          The electrolytic process by which a metal surface is converted to
          an oxide surface coating in a solution containing chromic acid.

          (g)  CHROMIUM:

          Hexavalent chromium.

          (h)  CONTROL EQUIPMENT:

          Any device which reduces emissions from the emissions collection
          system.

          (i)  DECORATIVE CHROME PLATING:

          The process by which chromium is electrodeposited from a solution
          containing compounds of chromium onto an object resulting in a
          chrome layer 1 micron (0.04 mil.) thick or less.
          
          (j)  EMISSION FACTOR:

          The mass of chromium emitted during a test conducted in the
          emissions collection system in accordance with ARB Test Method
          425, divided by the ampere-hours consumed by the tanks in the
          tested emissions collection system, expressed as the mass of
          chromium emitted per ampere-hour of electrical current consumed.

          (k)  EMISSIONS COLLECTION SYSTEM:

          A device or apparatus used to gather chromium emissions from the
          surface of a chrome plating or chromic acid anodizing tank or
          tanks.

          (l)  FACILITY:

          A business or businesses engaged in chrome plating or chromic
          acid anodizing which are owned or operated by the same person or

          calculated as the sum of emissions from the emissions collection
          system at the facility. The emissions from an emissions collection 
          system shall be calculated by multiplying the emission factor for 
          that emission collection system by the sum of ampere-hours consumed 
          during that year for all the tanks served by the emissions 
          collection system.

          (n)  HARD CHROME PLATING:

          The process by which chromium is electroplated from a solution
          containing compounds of chromium onto an object resulting in a
          chrome layer thicker than 1 micron (0.04 mil).

          emission factor based on tests conducted in accordance with ARB
          Test Method 425 or 14 mg/ampere-hour, whichever is less.

          change to any existing chrome plating or chromic acid anodizing
          facility holding a permit under the provisions of this
          regulation, the permit fee shall be recalculated to show any
          rating changes and pro-rated for the balance of the annual permit
          period.

          (e)  DUPLICATE PERMIT

          A request for a duplicate Permit to Operate shall be made in

          applicant shall be assessed a late fee penalty which is one and
          one-half times the applicable initial fee.  The assessment of a
          late fee penalty shall not limit the District's right to pursue
          any other remedy provided for by law.
