SDAPCD RULE X-D NATL.EMISS.STD.FOR BERYLLM.ROCKET MTR.FIRING          
LAST REVISED 11/08/76

          
          SUBPART D  -  National Emission Standard for Beryllium Rocket
                        Motor Firing (Delegation Effective 11/8/76)


                RULE 361.40.     APPLICABILITY

                The provisions of this subpart are applicable to rocket motor 
           test sites.  "New Sources" for this subpart are those sources 
           commencing construction or modification after December 7, 1971.


                RULE 361.41.     DEFINITIONS

                Terms used in this subpart are defined in Subpart A of this
           regulation, or in this rule as follows:

                (a)   "Rocket Motor Test Site" means any building, structure,
           facility, or installation where static test firing of a beryllium
           rocket motor and/or the disposal of beryllium propellant is 
           conducted.

                (b)   "Beryllium Propellant" means any propellant 
           incorporating beryllium.


                RULE 361.42.     EMISSION STANDARD

                (a)   Emissions to the atmosphere from rocket-motor test sites
           shall not cause time-weighted atmospheric concentrations of 
           beryllium to exceed 75 microgram minutes per cubic meter of air 
           within the limits of 10 to 60 minutes, accumulated during any 2 
           consecutive weeks, in any area in which an effect adverse to 
           public health could occur.

                (b)   If combustion products from the firing of beryllium
           propellant are collected in a closed tank, emissions from such tank
           shall not exceed 2 grams per hour and maximum of 10 grams per day.


                RULE 361.43.     EMISSION TESTING - ROCKET FIRING OR
                                 PROPELLANT DISPOSAL

                (a)   Ambient air concentrations shall be measured during and
           after firing of a rocket motor or propellant disposal and in such a
           manner that the effect of these emissions can be compared with the
           standard.  Such sampling techniques shall be approved by the 
           Control Officer.

                (b)   All samples shall be analyzed and results shall be
           calculated within 30 days after samples are taken and before any
           subsequent rocket motor firing or propellant disposal at the given
           site.  All results shall be reported to the Control Officer by a
           registered letter dispatched before the close of the next business 
           day following determination of such results.

                (c)   Records of air sampling test results and other data 
           needed to determine integrated intermittent concentrations shall be 
           retained at the source and made available, for inspection by the 
           Control Officer, for a minimum of 2 years.

                (d)   The Control Officer shall be notified at least 30 days 
           prior to an air a sampling test, so that he may at his option 
           observe the test.


                RULE 361.44.     STACK SAMPLING

                (a)   Sources subject to Rule 361.42(b) shall continuously
           sampled, during release of combustion products from the tank, in 
           such a manner that compliance with the standards can be determined.  
           The provisions of Rule 361.14 shall apply.

                (b)   All samples shall be analyzed, and beryllium emission 
           shall be determined within 30 days after samples are taken and 
           before any subsequent rocket motor firing or propellant disposal at 
           the given site.  All determinations shall be reported to the 
           Control Officer by a registered letter dispatched before the close 
           of the next business day following such determinations.

                (c)   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 Control Officer for a minimum 
           of 2 years.

                (d)   The Control Officer shall be notified at least 30 days 
           prior to an emission test, so that he may at his option observe the 
           test.
