Art Glass Rulemaking Decision Meeting 8/4/2016
Updated 8/15/2016
Text highlighted in green is a change we agreed to make at the 8/4 meeting.
Text in yellow is a decision made after the 8/4 meeting
Text in red is a decision that still needs to be made.
Decisions to make:
1. Should we replace the 99.0% baghouse source test requirement?
a. 0.005 gr/dscf PM at outlet? [EPA comment]
i. For Tier 1 and Tier 2
ii. Including non-filterable emissions? no
b. Method 29 metals at outlet?
i. If we require Method 29, do we set limits based on the results?
1. Require Tier 2s to source test + model + set usage limit for other metals, not just Cr? no
c. Should we update the Cr source test requirements for Tier 2s?
i. Require Cr test on outlet, instead of baghouse inlet
ii. By default use Method 29 & assume all Cr is Cr6. Facility has option to use Method 0061 to differentiate Cr3 and Cr6 if desired.
iii. Require facility to report full Method 29 list if doing Method 29
2. Should we change the 10 tpy applicability threshold?
a. “Tier Zero” from 1-10 tpy? [George]
i. Register only?
ii. Baghouse but no source test?
b. Set threshold based on metal raw material usage (lbs/year) [Glass Alchemy comment]
c. George’s proposal
i. 5 tpy threshold, include language that after compliance date, facilities that grow to be above threshold must have permit in hand and be in compliance
ii. Statewide registration if using >1 lb/year of metal HAP raw materials no
3. Require [triboelectric] baghouse leak detection systems? [EPA comment]
a. Could require for Tier 2 facilities only (that was the initial decision at the 8/4 meeting
b. Could decide not to require them, and say that monitoring pressure drop & inlet temp is enough (per Dave & Greg)
c. Could allow facilities to choose either grain loading source test or BLDS install (per George)
d. Could require Tier 2 to install BLDS (no grain loading test), allow Tier 1 to choose either grain loading test or BLDS
4. Should we add additional metals to list?
a. Cobalt and selenium (w added time to comply?)
b. All Method 29 metals?
c. Other metals?
5. Should we make the rule apply statewide? Yes apply statewide, per Jaclyn after 8/15 phone call w Keith Andersen (WR)
a. Are there facilities outside PDX that would be subject?
6. Clarify permit timing issues
a. Facilities can operate after submitting permit app, before DEQ issues permit?
7. Source test timing
a. If source test methods changed above, give “60 days from adoption or 60 days from baghouse install, whichever is later”?
8. Should we update the 24 hour Cr6 health benchmark in the rule to 5 ng/m3? [OHA comment]
9. Remove word ‘uncontrolled’ from 340-244-9090(1)
10. Definition of ‘raw material’ – does that include colored glass added to a batch?
a. Raw material definition should include some very concentrated glassy materials but doesn’t include ‘finished’ glass. George will draft definition of finished.
