Tenn. Comp. R. & Regs. 1200-03-11-.03 - BERYLLIUM

(1) Applicability. The provisions of this rule are applicable to 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.
(b) Machine shops which process beryllium, beryllium oxides, or any alloy when such alloy contains more than five (5) percent beryllium by weight.
(2) Definitions. Terms used in this Rule not defined herein shall have the meaning given to them in chapter 1200-03-2.
(a) ''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.
(b) ''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.
(c) ''Beryllium ore'' means any naturally occurring material mined or gathered for its beryllium content.
(d) ''Machine shop'' means a facility performing cutting, grinding, turning, honing, milling, deburring, lapping, electrochemical machining, etching, or other similar operations.
(e) ''Ceramic Plant'' means a manufacturing plant producing ceramic items.
(f) ''Foundry'' means a facility engaged in the melting or casting of beryllium metal or alloy.
(g) ''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.
(h) ''Incinerator'' 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.
(i) ''Propellant'' means a fuel and oxidizer physically or chemically combined which undergoes combustion to provide rocket propulsion.
(j) ''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.
(k) ''Propellant plant'' means any facility engaged in the mixing, casting, or machining of propellants.
(l) ''Rocket motor test site'' means any building, structure, facility, or installation where the static test firing of a beryllium rocket motor and/or the disposal of beryllium propellant is conducted.
(m) ''Beryllium propellant'' means any propellant incorporating beryllium.
(3) Emission Standard for Beryllium
(a) Emissions to the atmosphere from stationary sources subject to the provisions of this Rule shall not exceed ten (10) grams of beryllium over a twenty-four (24) hour period.
(b) The burning of beryllium and/or beryllium containing waste, except propellants, is prohibited except in incinerators, emissions from which must comply with the standards.
(c) 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.
(d) 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 a maximum of 10 grams per day.
(4) Stack Sampling:
(a) Each owner or operator required to comply with subparagraph (3) (a) of this rule shall test emissions from his source as follows:
1. Within ninety (90) days of February 9, 1977 in the case of an existing source or a new source which has initial startup date preceding February 9, 1977; or
2. Within ninety (90) days of startup in the case of a new source which does not have an initial startup date preceding February 9, 1977.
(b) The Technical Secretary shall be notified at least thirty (30) days prior to an emission test or air sampling test so that he at his option may observe the test.
(c) Samples shall be taken over such period or periods as are necessary to accurately determine the maximum emission which will occur in any twenty-four (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 twenty-four (24) hour period emissions will be based on that combination of factors which are likely to occur during the subject period and which results 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 Technical Secretary.
(d) Sources subject to subparagraph (3)(d) of this rule shall be continuously sampled, during release of combustion products from the tank, in such a manner that compliance with the standards can be determined.
(e) 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 Technical Secretary.
(f) All samples shall be analyzed and beryllium emissions and/or other results determined within thirty (30) days after the source test and/or samples are taken. In the case of sampling during a rocket motor firing or propellant disposal this calculation must occur before any subsequent rocket motor firing or propellant disposal at the given site. All determinations shall be reported to the Technical Secretary by written notification before the close of the next business day following such determination.
(g) Records of emissions test result, air sampling test results, and other data needed to determine total emissions and/or integrated intermittent ambient concentrations shall be retained at the source and made available, for inspection by the Technical Secretary, for a minimum of two (2) years.
(h) Emission of beryllium shall be determined by the Reference Method, as specified in the Federal Register, Volume 38, Number 66, April 6, 1973, or other techniques approved by the Technical Secretary.
