Draft Particulate and Opacity Standard Options
Original concept
Date | Pre 1970 Equipment | Post 1970 Equipment |
Now | .2 particulate and 40% opacity | .1 particulate and 20% opacity |
2015 | .20 particulate and 20% opacity | .1 particulate and 20% opacity |
2019 w/ option for extension | .10 particulate and 20% opacity | .10 particulate and 20% opacity |
Additional options for consideration by the Fiscal Advisory Committee**
Date | Pre 1970 Equipment | Post 1970 Equipment |
Now | .2 particulate and 40% opacity | .1 particulate and 20% opacity |
2015 w/option for extension | .20 particulate and 40% opacity | .1 particulate and 20% opacity |
2019 w/option for extension | .10 to .16 particulate* and 20% opacity if achievable, or: Alternate particulate standard Option 1: Source specific particulate standard based on new or upgraded dust collector Option 2: Less stringent particulate standard if modeling shows no violation Alternate opacity limit: Source specific opacity limit based on in-stack monitoring data Exemptions (particulate & opacity): Exemptions for back up boilers, limited production, or short non-compliance time periods | .10 to .15 particulate* and 20% opacity if achievable, or: Alternate particulate standard Option 1: Source specific particulate standard based on new or upgraded dust collector Option 2: Less stringent particulate standard if modeling shows no violation Alternate opacity limit: Not applicable because the limit is not changing
Exemptions (particulate & opacity): Exemptions for back up boilers, limited production, or short non-compliance time periods |
*Exact value to be based on review of source test data and consultation with the fiscal advisory committee.
** The fiscal advisory committee may consider additional options as we gather more information.
Original concept:
Date | Pre 1970 Equipment | Post 1970 Equipment |
Now | .2 particulate and 40% opacity | .1 particulate and 20% opacity |
2015 | .20 particulate and 20% opacity | .1 particulate and 20% opacity |
2019 w/ option for extension | .10 particulate and 20% opacity | .10 particulate and 20% opacity |
REVISED OPTIONS:
Date | Pre 1970 Equipment | Post 1970 Equipment |
Now | 0.2 gr/dscf and 40% opacity | 0.1 gr/dscf and 20% opacity |
2017 w/option for extension | 0.20 gr/dscf and 40% opacity with continuous opacity monitor for sources < NAAQSi | 0.15 gr/dscf and 20% opacity for sources < NAAQS |
2019 w/option for extension | 0.15 gr/dscf and 20% and for sources > NAAQS, new high efficiency multiclones | 0.15 gr/dscf and 20% and for sources > NAAQS, new high efficiency multiclones |
Now - 2019 | Sources that burn hog fuel/residual oil ONLY during NG curtailment - 0.20 gr/dscf and 40% opacity | |
