Rule No.

Rule Title

Summary of significant changes

Notes

9000

Applicability

Applicability criteria moved from 9000 to 9010, definitions.

Temp rule version defined CAGMs in the applicability section, better to define in the definitions.

9005

Compliance dates

New section

Compliance dates specified for new CAGMs, and Tier 1 changing to Tier 2

Necessary

 

NS Glass may grow to Tier 2

9010

Definitions

Several changes, among them are:

 

Definition of CAGM broadened to include manufacturing any amount of colored art glass

 

Applicability lowered to 5 tons per year, but I also suggest changing to pounds per month basis to make applicability easier to determine.

 

Example given to clarify glassified raw materials.

 

 

 

Don’t panic, the rules still only have requirements for Tier 1 and Tier 2, but this was necessary.

 

 

 

 

 

 

 

To clarify

9020

Permit Required

Added clarification that operating without a permit is not a violation.

Necessary to eliminate unintended violations

9030

Requirements that apply to Tier 2 CAGMs

Effective immediately, 4 HAPs may not be used in uncontrolled furnaces.

 

Effective Feb 1, 2018 list expands to 8 HAPs that may not be used in uncontrolled furnaces.

 

9040

Operating Restrictions That apply to Tier 2 CAGMs

Name changed to Chromium Usage Restrictions That apply to Tier 2 CAGMs

 

Revised to cover 3 options:

1. Use M29, assume all Cr is CrVI

2. Use CrVI to determine CrVI from CrIII use

3. Use CrVI to determine CrVI from CrVI use

 

M29 test added, outlet only

 

CrVI test revised to outlet only, requirement to test for PM at the same time dropped

 

Modeling put into its own section

Section only addresses chromium

 

 

 

Primary option is no. 1, others just in case

 

 

 

 

 

 

 

PM dropped because it’s unnecessary

9050

Requirements that apply to Tier 1 CAGMs

Revised to follow same structure as 9030

 

2 compliance options deleted (test, model, show impacts less than x ng/m3; and request permit limit prohibiting use of one or more HAPs)

Clarify

 

 

Not being used by anyone

9060

Operating restrictions that apply to Tier 1 CAGMs

Deleted

No longer necessary

9070

Emission control device requirements

Option of doing PM test for 0.005 gr/dscf, or install BLDS

Time allowed for either increased to 90 days after baghouse becomes operational.

 

New section added as a placeholder for BLDS requirements if needed

Suggested approach

9080

Emission control device monitoring

New section added as a placeholder for BLDS requirements if needed

 

9090

Other Metal HAPs
