Each supplementary control system shall contain the following elements:
Radius for SO2 Emissions at Maximum Production Capacity1
Emissions rate in tons per hour | Emission rate in grains per sec. | Radius in kilometers |
16 or less | 4,000 or less | 11 |
24 | 6,000 | 16 |
32 | 8,000 | 24 |
40 | 10,000 | 32 |
48 or more | 12,000 or more | 40 |
1 Maximum emission rates for periods not to exceed 24 hours. Minimum radii may be determined from the table by linear interpolation.
Such plans may, but need not, include the operation of a joint SCS system. Each NSO shall require adherence by the NSO applicant owner to the joint plan for emission curtailment and allocation of liability, unless the issuing agency determines, pursuant to the provisions of paragraph (c)(2) of this section, that the NSO applicant's DLA does not overlap with that of any other smelter.
