(1) Emissions to the atmosphere may not exceed 10 grams of beryllium over a 24-hour period from:
NR 448.03(1)(a)

NR 448.04
NR 448.04
Stack emission sampling and emission limits. NR 448.04(1)(1) Unless a waiver of emission testing is obtained from the department, each owner or operator of a source covered under
s. NR 448.03 (1) on which construction or modification commenced after February 1, 1984 shall test emissions from the source within 90 days of startup.
NR 448.04(1)(a)
(a) The department shall be notified at least 30 days prior to an emission test to afford it the opportunity to have a representative present to witness the testing procedures.
NR 448.04(1)(b)
(b) Samples shall be taken over such a period as is 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 may 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 department.
NR 448.04(1)(c)
(c) 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 department by registered letter dispatched before the close of the next business day following the determinations.
NR 448.04(1)(d)
(d) 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 a department representative for a minimum of 2 years.
NR 448.04(2)
(2) Emissions to the atmosphere from rocket-motor test sites may 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 would occur.
NR 448.04(3)
(3) If combustion products from the firing of beryllium propellant are collected in a closed tank, emissions from such tank may not exceed 2.0 grams per hour and a maximum of 10 grams per day.
NR 448.04(4)(a)(a) Sources subject to
sub. (3) shall be continuously sampled during the release of combustion products from the tank so that compliance with the standards can be determined. The tests shall be conducted in accordance with Method 103 or Method 104 of
40 CFR part 61, Appendix B, incorporated by reference in
s. NR 484.04 (23).
NR 448.04(4)(b)
(b) All samples shall be analyzed and beryllium emissions shall be determined within 30 days after samples are taken and before any subsequent rocket motor firing or propellant disposal at the same site. All determinations shall be reported to the department by registered letter dispatched before the close of the next business day following the determination.
NR 448.04(4)(c)
(c) Records of emission test results and other data needed to determine total emissions shall be retained at the source and shall be made available for inspection by a department representative for a minimum of 2 years.
NR 448.04(4)(d)
(d) The department shall be notified at least 30 days prior to an emission test to afford it the opportunity to have a representative present to witness the testing procedures.

NR 448.05
Emission testing — rocket firing or propellant disposal. NR 448.05(1)(1) 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 set in
s. NR 448.04 (2). The sampling techniques shall be approved by the department.
NR 448.05(2)
(2) 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 same site.
