# §60.282a. Standard for filterable particulate matter.

- (a) On and after the date on which the performance test required to be conducted by [§ 60.8](/cfr/40/60.8.md) is completed, no owner or operator subject to the provisions of this subpart shall cause to be discharged into the atmosphere:
  - (1) **From any modified recovery furnace any gases which—**
    - (i) Contain filterable particulate matter in excess of 0.10 gram per dry standard cubic meter (g/dscm) (0.044 grain per dry standard cubic foot (gr/dscf)) corrected to 8-percent oxygen.
    - (ii) Exhibit 20-percent opacity or greater, where an electrostatic precipitator (ESP) emission control device is used, except where it is used in combination with a wet scrubber.
  - (2) **From any new or reconstructed recovery furnace any gases which—**
    - (i) Contain filterable particulate matter in excess of 0.034 g/dscm (0.015 gr/dscf) corrected to 8-percent oxygen.
    - (ii) Exhibit 20-percent opacity or greater, where an ESP emission control device is used, except where it is used in combination with a wet scrubber.
  - (3) From any modified or reconstructed smelt dissolving tank, or from any new smelt dissolving tank that is not associated with a new or reconstructed recovery furnace subject to the provisions of [paragraph (a)(2)](#a-2) of this section, any gases which contain filterable particulate matter in excess of 0.1 gram per kilogram (g/kg) (0.2 pound per ton (lb/ton)) of black liquor solids (dry weight).
  - (4) From any new smelt dissolving tank associated with a new or reconstructed recovery furnace subject to the provisions of [paragraph (a)(2)](#a-2) of this section, any gases which contain filterable particulate matter in excess of 0.060 g/kg (0.12 lb/ton) black liquor solids (dry weight).
  - (5) **From any modified lime kiln any gases which—**
    - (i) Contain filterable particulate matter in excess of 0.15 g/dscm (0.064 gr/dscf) corrected to 10-percent oxygen.
    - (ii) Exhibit 20-percent opacity or greater, where an ESP emission control device is used, except where it is used in combination with a wet scrubber.
  - (6) **From any new or reconstructed lime kiln any gases which—**
    - (i) Contain filterable particulate matter in excess of 0.023 g/dscm (0.010 gr/dscf) corrected to 10-percent oxygen.
    - (ii) Exhibit 20-percent opacity or greater, where an ESP emission control device is used, except where it is used in combination with a wet scrubber.
- (b) These standards apply at all times as specified in §§ [60.284a](/cfr/40/60.284a.md) and [60.285a](/cfr/40/60.285a.md).
- (c) The exemptions to opacity standards under [40 CFR 60.11(c)](/cfr/40/60.11.md?p=c) do not apply to subpart BBa.
