                           Emission Standard for Beryllium

          (a)  Definitions

               (1)  BERYLLIUM  means  the element beryllium.  Where weights
                    or  concentrations  are   specified,  such  weights  or
                    concentrations apply to beryllium  only,  excluding the
                    weight or concentration of any associated elements.

               (2)  BERYLLIUM ALLOY means any metal to which beryllium  has
                    been  added  in order to increase its beryllium content
                    and which contains  more  than 0.1 percent beryllium by
                    weight.

               (3)  BERYLLIUM-CONTAINING WASTE  means material contaminated
                    with  beryllium  and/or  beryllium  compounds  used  or
                    generated during any process  or operation performed by
                    a source subject to this rule.

               (4)  BERYLLIUM  ORE means any naturally  occurring  material
                    mined or gathered for its beryllium content.

               (5)  CERAMIC PLANT  means  a  manufacturing  plan  producing
                    ceramic items.

               (6)  EXTRACTION PLANT means a facility chemically processing
                    beryllium  ore to beryllium metal, alloy, or oxide,  or
                    performing any  of  the  intermediate  steps  in  these
                    processes.

               (7)  FOUNDRY  means  a  facility  engaged  in the melting or
                    casting of beryllium metal or alloy.

               (8)  INCINERATOR  for the purpose of this Rule  only,  means
                    any furnace used  in  the  process of burning waste for
                    the primary purpose of reducing the volume of the waste
                    by removing combustible matter.

               (9)  MACHINE  SHOP  means  a  facility  performing  cutting,
                    grinding, turning, honing, milling, deburring, lapping,
                    electrochemical machining,  etching,  or  other similar
                    operations.

               (10  PROPELLANT  means  a  fuel  and oxidizer physically  or
                    chemically  combined  which  undergoes   combustion  to
                    provide rocket propulsion.

               (11) PROPELLANT  PLANT  means  any facility engaged  in  the
                    mixing, casting, or machining of propellant.

          (b)  Emission Standard

               (1)  No person shall discharge or cause the discharge to the
                    atmosphere of more than ten  grams  of beryllium over a
                    24-hour period from the following stationary sources:

                    (A)  Extraction  plants,  ceramic  plants,   foundries,
                         incinerators, and propellant plants which  process
                         beryllium   ore,   beryllium,   beryllium   oxide,
                         beryllium  alloys,  or beryllium-containing waste;
                         and

                    (B)  Machine shops which process  beryllium,  beryllium
                         oxides, or any alloy when such alloy contains more
                         than five percent beryllium by weight.

               (2)  The  burning  of  beryllium and/or beryllium-containing
                    waste,  except propellants,  is  prohibited  except  in
                    incinerators,  emissions  from  which  must comply with
                    this rule.

          (c)  Testing Procedure

               (1)  Unless  a waiver of emission testing is obtained  under
                    Rule 1001  (b),  each  owner  or  operator  required to
                    comply with paragraph (b)(1) shall test emissions  from
                    his source;

                    (A)  within 90 days of the effective date of this Rule;
                         and

                    (B)  within  90  days  of  startup in the case of a new
                         source.

               (2)  The Air Pollution Control Officer  shall be notified at
                    least 30 days prior to an emission test so that he may,
                    at his option, observe the test.  At  his  option,  the
                    Air  Pollution Control Officer may conduct the required
                    test.

               (3)  Samples shall be taken over such a period or periods as
                    are  necessary  to  accurately  determine  the  maximum
                    emissions  which  will  occur  in  any  24-hour period.
                    Where emissions depend upon the relative  frequency  of
                    operation  of  different  types of processes, operating
                    hours,  operating  capacities,  or  other  factors  the
                    calculation of maximum 24-hour period emissions will be
                    based on that combination of factors which is likely to
                    occur during the subject period and which result in the
                    maximum emissions.   No  changes in the operation shall
                    be  made  which  would potentially  increase  emissions
                    above that determined  by  the most recent source test,
                    until  a  new  emission  level has  been  estimated  by
                    calculation  and  the  results   reported  to  the  Air
                    Pollution Control Officer.

               (4)  All samples shall be analyzed and  beryllium  emissions
                    shall  be  determined  within  30 days after the source
                    test.  All determinations shall  be reported to the Air
                    Pollution  Control  Officer  by  a  registered   letter
                    dispatched  before  the  close of the next business day
                    following such determination.

               (5)  Records of emission test results  and other data needed
                    to determine total emissions shall  be  retained at the
                    source  and made available for inspection  by  the  Air
                    Pollution Control Officer for a minimum of two years.
