DEPARTMENT OF ENVIRONMENTAL QUALITY

DIVISION 244

OREGON FEDERAL AND STATE HAZARDOUS AIR POLLUTANT PROGRAM

General Provisions for Stationary Sources

340-244-0010

Policy and Purpose

The Environmental Quality Commission finds that certain air contaminants for which there are no ambient air quality standards may cause or contribute to an identifiable and significant increase in mortality or to an increase in serious irreversible or incapacitating reversible illness or to irreversible ecological damage, and are therefore considered to be hazardous air pollutants. It shall be the policy of the Commission that no person may cause, allow, or permit emissions into the ambient air of any hazardous substance in such quantity, concentration, or duration determined by the Commission to be injurious to public health or the environment. The purpose of this Division is to establish emissions limitations on sources of these air contaminants. In order to reduce the release of these hazardous air pollutants and protect public health and the environment, it is the intent of the Commission to adopt by rule within this Division the source category specific requirements that are promulgated by the EPA, and state standards to reduce the release of these hazardous air pollutants. Furthermore, it is hereby declared the policy of the Commission that the standards contained in this Division are considered minimum standards, and as technology advances, protection of public health and the environment warrants, more stringent standards may be adopted and applied.

Chromium Usage Restrictions That Apply To Tier 2 CAGMs

(1) On and after the compliance date, a Tier 2 CAGM may only use raw materials containing chromium in glass-making furnaces that are controlled by an emission control device approved by DEQ, and only after DEQ has approved annual and daily maximum chromium usage rates that will prevent the source impacts from exceeding either of the following:

(a) An annual acceptable source impact level for chromium VI concentration of 0.08 nanograms per cubic meter at the nearest sensitive receptor approved by DEQ. Sensitive receptors include, but are not limited to: residences, hospitals, schools, daycare facilities, elderly housing and convalescent facilities; and

(b) A daily acceptable source impact level for chromium VI concentration of 5 nanograms per cubic meter at any off-site modeled receptor.

(2) A Tier 2 CAGM may request that DEQ approve annual and daily maximum allowable usage rates for using total chromium, chromium III, chromium VI, or any combination of these as raw materials. The requirements for establishing maximum allowable usage rates are:

(a) Determine one or more chromium VI emission rate(s) using one or more of the procedures specified in subparagraphs (A) through (C).

(A) For use of chromium in any oxidation state as a raw material, determine the total chromium emission rate using the source test requirements in section (4) and assume that only chromium VI is emitted when chromium in any oxidation state is used as a raw material.

(B) For use of chromium III as a raw material, determine a specific chromium VI emission rate when using chromium III as a raw material using the source test requirements in section (5).

(C) For use of chromium VI as a raw material, determine a specific chromium VI emission rate when using chromium VI as a raw material using the source test requirements in section (5).(b) Perform the dispersion modeling in section (6) to establish annual and daily maximum usage rates based on the modeled source impacts. The modeled source impacts must not exceed the acceptable source impact levels set forth in section (1).

(c) If multiple chromium VI emission rates are determined under subsection (a), the maximum usage rates may vary depending on the oxidation states of the chromium used as raw materials at any particular time, provided the source impacts do not exceed the acceptable source impact levels set forth in section (1).

(3) After DEQ establishes the maximum allowable chromium usage rates for a CAGM’s glass-making furnace or glass-making furnaces, the CAGM must comply with the rates DEQ establishes.

(4) A source test required under paragraph (2)(a)(A) must be performed as specified below:

(A) Test using EPA Method 29 or an equivalent DEQ-approved method and submit a source test plan detailing the approach to DEQ for approval;

(B) Test at the outlet of the emission control device on a controlled glass-making furnace;

(C) Test while making a glass that contains a high percentage of chromium raw materials as compared to other formulas used by the CAGM; and

(5) A source test required under paragraph (2)(a)(B) or (2)(a)(C) must be performed as specified below:

(A) Test using DEQ-approved protocols and methods for total chromium and chromium VI using a DEQ-approved testmethod and submit a source test plan detailing the approach to DEQ for approval;

(B) Test for chromium and chromium VI at the outlet of the emission control device on a controlled glass-making furnace;

(C) Test while making a glass that DEQ agrees is made under the most oxidizing combustion conditions and that contains a high percentage of chromium III raw materials as compared to other formulas used by the CAGM; and

(6) Dispersion modeling required under subsecton (2)(b) must be performed as follows:

(A) Submit a modeling protocol for DEQ approval;

(B) Use models and protocols approved by DEQ;

(D) Establish maximum chromium usage rates so that the source impact will not exceed either of the acceptable source impact levels specified in section (1).

(7) Each Tier 2 CAGM must keep daily records of all glass formulations produced and, until such time as the Tier 2 CAGM has installed all emission control devices required under OAR 340-244-9030, provide to DEQ a weekly report of the daily amount of each glass-making HAP used as a raw material.

DAVIS George, 2016-08-17T10:26:00Z

1. Definition of CAGM has been broadened to include manufacturing any amount of colored art glass. But don’t panic, the main requirements still only apply to Tier 1 and Tier 2 CAGMs. The reason for broadening the definition is that is smaller than Tier 1 could grow and become a Tier 1 - note 9005(3) below where this comes into play.

2. All of the criteria have been moved into the definitions in 9010.

DAVIS George, 2016-08-17T10:26:00Z

New section for compliance dates added. Original rules didn’t account for possible new CAGMs, or a CAGM going from Tier 1 to Tier 2. This section addresses compliance dates for these situations.

DAVIS George, 2016-08-17T10:26:00Z

Added on 8/12--- extensions to compliance dates for reasons beyond CAGMs control

Lots of precedents for this kind of thing.

DAVIS George, 2016-08-17T10:26:00Z

Definition moved from Applicability 9000 to here

WESTERSUND Joe, 2016-08-17T14:48:00Z
What’s the purpose of this paragraph?

Garrahan Paul, 2016-08-17T10:26:00Z
And renumber the rest of the definitions, then cross-check references to them.

If you don’t define this term, then everywhere you refer to these compliance dates in the rules, I recommend that you add the phrase “set forth in OAR 340-244-9005.”

DAVIS George, 2016-08-17T10:26:00Z
Temp rules were inconsistent and used terms “chromium” and “total chromium”. This draft attempts to use these terms consistently. Term “total chromium” has been added below.

WESTERSUND Joe, 2016-08-17T14:48:00Z
What’s the meaning of recycled here?

DAVIS George, 2016-08-17T10:26:00Z
In temp rule this duplicated the definition of “raw materials”, removed here and replaced with reference to “raw materials”.

DAVIS George, 2016-08-17T10:26:00Z
New definition added to allow clearer language in the rule.

DAVIS George, 2016-08-17T10:26:00Z

1. “Metal HAP” replaced with “glass-making HAP” because arsenic and selenium are not metals.

2. Definition expanded to include cobalt and selenium.

DAVIS George, 2016-08-17T10:26:00Z
“metal HAPs” replaced with “glass-making HAPs”, see comment above.

WESTERSUND Joe, 2016-08-17T14:56:00Z
I find this definition confusing.

If someone adds colored glass to a batch, it sounds like it is a raw material if it is “used as a coloring agent”.

If you melt two colored glasses together to combine the colors, it sounds like both are then raw materials, is that the intended effect?

WESTERSUND Joe, 2016-08-17T15:05:00Z
What about glass that contains HAPs that don’t change the color? Lead can be used up to 30% by weight in glass and it’s still clear. Arsenic can be used to help remove bubbles. Some metals are added to neutralize the color of other trace contaminants, etc.

DAVIS George, 2016-08-17T10:26:00Z
Example added to clarify. Paul, is this ok?

Garrahan Paul, 2016-08-17T10:26:00Z
Example are OK, but can sometimes then be used to limit interpretation of a definition more than intended. What do you think of my proposed alternative?

Garrahan Paul, 2016-08-17T10:26:00Z
My language is intended to clarify what happens if a facility bounces above and below the threshold from month to month. Maybe my suggestion complicates things further?

DAVIS George, 2016-08-17T10:26:00Z

Note alternative definitions, one set based on tons per year, the other based on pounds per month.

I suggest the pound per month approach, as it is easier to track and doesn’t require a 12-month look-back to see if the facility has met the criteria. It also makes the compliance dates simpler.

Suggested pound per month numbers (825 and 16,650) are approximately equivalent to 5 tpy and 100 tpy, respectively.

DAVIS George, 2016-08-17T10:26:00Z
New definition added for clarity.

DAVIS George, 2016-08-17T10:26:00Z
OK, these rules are likely to take effect after September 1, so leaving the September 1 date in the rules doesn’t make sense. However, this is an attempt to note the requirement, and it makes more sense once you read (2) just below.

Paul?

Garrahan Paul, 2016-08-17T10:26:00Z
But they were in effect before September 1. I don’t think you want to mess with lots of language to try to account of these amendments. Those sources must have applied for a permit by Sept. 1 under the temporary rules. You’re not changing that requirement now. If they haven’t done so, then they’re in violation.

Garrahan Paul, 2016-08-17T10:26:00Z
You need to specify the rules you’re referencing and not simply refer to “these rules.”

DAVIS George, 2016-08-17T10:26:00Z

216-0020(3) is the requirement to have an ACDP before constructing, operating, etc.

There does not appear to be a similar rule under Title V; instead there is a duty to apply.

DAVIS George, 2016-08-17T10:26:00Z
Section 2 is intended to clarify that a CAGM is not in violation of operating without a permit.

DAVIS George, 2016-08-17T10:26:00Z
This applies to new CAGMs, essentially parallels the requirement in 216-0020(3). May be redundant, but added for clarity.

Garrahan Paul, 2016-08-17T10:26:00Z
Can delete this if you add the definition of “compliance date” as I have recommended, above.

DAVIS George, 2016-08-17T10:26:00Z
Rewritten for clarity, also to take into account the MAO

DAVIS George, 2016-08-17T10:26:00Z

Phase-in of 4 more HAPs, 18 months after Sept 1, 2016

DAVIS George, 2016-08-17T10:26:00Z

This section is specific to chromium, name changed to reflect that.

Significant rewriting to clarify the requirements.

Joe Westersund, 2016-08-17T10:26:00Z
Is source the furnace or the facility?

Gfd - facility

Does not include background conc, this is a limit on the contribution of this facility.

Gfd - correct, source impact only

Procedure for requesting chromium usage rates. Gets complicated because it includes options for total chromium, chromium III or chromium VI.

Testing requirements are different for total chromium vs chromium III or VI, so a new testing requirement was added below (Method 29).

This suggested edit is to make this language run parallel to the language in section (5) requiring source testing.

Not needed if you agree to define the term “compliance date.”

Section (1) revised to parallel the language for Tier 2 CAGMs.

Eliminated two of the compliance options (source test and model to show impacts less than specified levels, and option to get a permit limit prohibiting use of certain HAPs). Neither of these are being used.

Redundant and outdated, therefore deleted.

Option proposed:

Source test for PM and meet 0.005 gr/dscf, or
