(102) "Opacity" means the degree to which emissions, excluding uncombined water, reduce the transmission of light and obscure the view of an object in the background as measured by EPA Method 9 or other method(s), as specified in each applicable rule.

 

 

340-240-0030(30) "Opacity" means the degree to which an emission reduces transmission of light and obscures the view of an object in the background as measured in accordance with the Department's Source Sampling Manual (January, 1992). Unless otherwise specified by rule, opacity must be measured in accordance with EPA Method 9. For all standards, the minimum observation period must be six minutes, though longer periods may be required by a specific rule or permit condition. Aggregate times (e.g. 3 minutes in any one hour) consist of the total duration of all readings during the observation period that exceed the opacity percentage in the standard, whether or not the readings are consecutive. Alternatives to EPA Method 9, such as a continuous opacity monitoring system (COMS), alternate Method 1 (LIDAR), or EPA Methods 22, or 203, may be used if approved in advance by the Department, in accordance with the Source Sampling Manual.

Change the oxygenated gasoline requirement in control areas since the October 31, 2007 is past. Require oxygenated gasoline if required under an applicable attainment or maintenance plan adopted by the Environmental Quality Commission, and apply it to the oxygenated gasoline control areas: Clackamas, Multnomah, Washington and Yamhill Counties.

The October 31, 2007 date has past. DEQ’s 2004 CO maintenance plan states that Section 175A(d) of the Clean Air Act provides that any control strategies removed upon redesignation to attainment must be reinstated if the area violates the air quality standard. The provisions of this section of the Contingency Plan are dictated by that Clean Air Act requirement.

If the Portland area violates the NAAQS for CO, the requirement to use wintertime oxygenated fuel in Clackamas, Multnomah, Washington, and Yamhill Counties will be reinstated.

Delete 40% opacity limit and make a provision for soot blowing and grate cleaning:

“No person may emit or allow to be emitted any air contaminant into the atmosphere from any air contaminant stack or emission point that equals or exceeds 20% opacity as a six-minute average except as allowed in section (2).”

 

DEQ is proposing the changes for the following reasons:

 Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT.

 Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.

 More and more areas of the state are special control areas due to population increases.

 EPA’s adoption of a new PM2.5 24-hour NAAQS has resulted in 2 nonattainment areas, with a third meeting the definition but not legally designated as such. This proposed rule change will reduce opacity in all areas and will help prevent future problems.

 Phased compliance will give sources that cannot meet the new standards time to comply.

Make the 20% limit applicable to all non-fugitive sources in the state. Change limit to a 6-minute average instead of a 3-minute aggregate.

DEQ is proposing the change because of the following reasons:

 An opacity standard based on a 6-minute average is no more or less stringent than a standard based on an aggregate of 3 minutes in any hour. Theoretically, either basis could be more stringent than the other, but practically, sources do not typically have intermittent puffs of smoke. If there is an upset that lasts longer than 3 minutes, it usually lasts longer than 6 minutes, as well.

 Other reasons for changing to a 6 minute average include:

◦  A reference compliance method has not been developed for the 3 minute standard.

◦  EPA method 9 results are reported as 6-minute averages.

◦  The 3-minute standard adds more cost to data acquisition systems for continuous opacity monitoring systems. Many of the COMS are designed for 6-minute averages, so they have to be modified to record and report data for the 3-minute standard.

◦  Compliance with a 6 minute average can be determined with 24 readings (6-minute observation period); whereas, compliance with the 3-minute standard may require as many as 240 readings (60 minute observation period). In addition, it is DEQ’s policy that the inspector observes the source for at least 6 minutes before making a compliance determination.

Add requirement that changes that are required to obtain a permit under OAR 340 division 216 would not qualify as a Type 1 or Type 2 changes.

Corrects a problem regarding changes that otherwise qualify as a Type 1 change but should be required to obtain a permit under division 216. There have been instances when companies have replaced a NESHAP subject chrome plating line with entirely new equipment or have replaced the control device.  In each instance the associated emissions are well below the de minimis rate and the change meets the Type 1 criteria.  The review process in these instances is more complicated than for what Type 1 category was intended and therefore  a permit is required.

Sources with permits in effect on May 1, 2011 get an initial PM2.5 PSEL based on the PM2.5 fraction of the PM10 PSEL are not required to do any modeling or go through NSR/PSD as required in OAR 340-222-0041(4) if the PM2.5 PSEL is greater than an SER over the PM2.5 netting basis. The exception is if a source needs a third extension of an NSR/PSD permit under OAR 340-224-0030(2)(a)(C). A new application would be required since DEQ does not grant three extensions and that would require a whole analysis of PM2.5. PM2.5 protected under first 2 extensions of an NSR/PSD permit.

Clarification. If the PM10 PSEL was incorrect, it should be corrected before setting the PM2.5 PSEL based on the PM2.5 fraction of the PM10 PSEL. This is a one-time correction only for the initial PSEL and netting basis.

Add “(c) If after establishing the initial PSEL for PM2.5 in accordance with this rule and establishing the initial PM2.5 netting basis in accordance with OAR 340-222-0046, the PSEL is more than nine tons above the netting basis, any future increase in the PSEL for any reason would be subject to OAR 340-222-0041(4).”

Initially PM2.5 PSELs will be exempt from triggering ambient air quality modeling or NSR/PSD because DEQ did not want a source to trigger any new requirements if it was not making any modifications or production increases when PM2.5 was added as a regulated pollutant. If the PM2.5 PSEL is more than 9 tons above the netting basis, then any future increase will trigger modeling or NSR/PSD.

Add “(6) If a PSEL is established or revised to include emissions from activities that existed at a source prior to April 1, 2014 and which were previously considered categorically insignificant activities prior to April 1, 2014, and results in a PSEL greater than the netting basis by greater than or equal to an SER as a result of this revision, the requirements of OAR 340-222-0041(4) do not apply. If the revised PSEL is greater than or equal to the SER above the netting basis, any future increase in the PSEL for any reason would be subject to OAR 340-222-0041(4).”

The RICE NESHAP has requirements for emergency generators that were previously considered categorically insignificant activities. DEQ is also making changes to fuel and gas burning equipment included in categorically insignificant activities. A source could have numerous emissions units that burn fuel or gas, whose emissions could be greater than one ton in the aggregate. Because of these changes to categorically insignificant activities, DEQ realizes that existing sources that have these activities should not be penalized. Therefore, DEQ is grandfathering sources that had emergency generators or small fuel or gas burning equipment as of April 1, 2014 from potentially triggering NSR. Sources would be required to get a permit if needed but could limit PTE to stay on a general permit.

Add a provision for transferring the netting basis and SER to a combined heat and power facilities that supports the primary SIC.

If you split a source into 2 separate sources, those two sources can have different SICs but the netting basis and SER must stay with the original source except in the case of a combined heat and power facility that supports the primary SIC. The netting basis protects the airshed. If the new SIC source is grandfathered, then they wouldn’t have to do an AQ analysis. The source with the new SIC should be considered a new source and should potentially trigger NSR/PSD. EPA is __________ for combined heat and power facilities.

Add an applicability section for sustainment areas which are areas violating the NAAQS but not yet designated as nonattainment areas

There are areas that violate the NAAQS but have not yet been designated nonattainment by EPA.  Sources in these areas would fall under the requirements for attainment or unclassified areas rather than nonattainment areas. DEQ is creating requirements for sources in these “sustainment areas” in order to improve air quality and to enable the source to construct or modify. Without these rules, sources would not be able to construct or modify because they would never be able to show compliance with the NAAQS since the background concentration is already above the NAAQS.

Add an applicability section for reattainment areas which are areas that are currently designated as nonattainment areas but are meeting ambient air quality standards and have not yet been designated as maintenance areas

It takes time to develop maintenance plans for nonattainment areas before EPA can redesignate the area to maintenance. After DEQ has three years of data showing that the area is meeting the NAAQS but before the maintenance plan can be developed, DEQ wants to designate these areas as reattainment areas. This will give source more flexibility in permitting requirements before the area is redesignated as maintenance.

The demonstration that the air quality impact from the emissions increase would not cause or contribute to an exceedance of any air quality standard requires a competing source analysis and representative background data if the new source impacts are above the SIL. DEQ has not allowed post construction monitoring to be substituted for preconstruction monitoring. Ambient air data from the same monitor that provided the background concentration used in the modeling is used to ensure that air quality is below the NAAQS after construction. Therefore, DEQ is changing this requirement to exempt a source from preconstruction monitoring if representative or conservative general background concentration data is available.

Add “For increases of PM2.5 precursors equal to or greater than the significant emission rate, the owner or operator must provide an analysis of PM2.5 air quality impacts based on all increases of direct PM2.5 and PM2.5 precursors.”

Add “The owner or operator must not cause or contribute to a new violation of an ambient air quality standard even if the single source impact is less than the significant impact level, in accordance with OAR 340-202-0050(2).”

In a recent lawsuit, the Sierra Club argued that EPA lacks authority to establish Significant Impact Levels (SILs) because a proposed source or modification in an area that is close to violating the NAAQS or an increment could violate the NAAQS or increment even if its emissions would have an ambient impact below the SIL. The U.S. Court of Appeals for the D.C. Circuit vacated and remanded to EPA certain aspects of a 2010 agency rule regarding SILs and the Significant Monitoring Concentration (SMC) for fine particulate matter (PM2.5). Therefore, DEQ has added the requirement that the new or modified source must not cause or contribute to a new violation of an ambient air quality standard even if the single source impact is less than the SIL. This safeguard ensures that a new or modified source will not significantly impact the area.

(e) Offsets obtained for a previous PSEL increase that did not involve resetting the netting basis can be credited toward offsets currently required for a PSEL increase.

 

If a new source was first permitted at 50 tpy, and assuming they don’t go through PSD, then their netting basis is zero and they need to get offsets according to the formula. If they then want to increase the PSEL to 75 tpy, their netting basis is still zero and on the face of it, they need to get offsets based on a 75 tpy increase. One might hope that DEQ would see fit to give credit for offsets used for the original 50 tpy and the source would only have to get offsets for the 25 tpy increase, but the rules don’t seem to contemplate that situation.

(2) The owner or operator of an existing source who is unable to comply with OAR 340-228-0210(1)(a), (c), or (d) may request that DEQ grant an extension allowing the source up to one year to comply with the standard, if such period is necessary for the installation of controls.

DEQ is proposing the change because of the following reasons:

 Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT.

 Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.

 More and more areas of the state are special control areas due to population increases.

 EPA’s adoption of a new PM2.5 24-hour NAAQS has resulted in 2 nonattainment areas, with a third meeting the definition but not legally designated as such. This proposed rule change will reduce grain loading in all areas and will help prevent future problem.

 Phased compliance will give sources that cannot meet the new standards time to comply.

 Changes would make it easier

 to determine compliance for the both the source and the DEQ.

Change the grain loading requirements for fuel burning equipment to the following:

(b) 0.1 grains per dry standard cubic foot for sources installed, constructed, or modified after June 1, 1970, except as required by sections (c) and (d).

(c) 0.10 grains per dry standard cubic foot if the source is located within 5 miles of a PM10/PM2.5 sustainment area, nonattainment area, or maintenance area and was installed, constructed or modified after June 1, 1970.

(d) 0.10 grains per dry standard cubic foot for all sources on or after January 1, 2019.

(2) The owner or operator of an existing source who is unable to comply with OAR 340-228-0210(1)(a), (c), or (d) may request that DEQ grant an extension allowing the source up to one year to comply with the standard, if such period is necessary for the installation of controls.

DEQ is proposing the change because of the following reasons:

 Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT.

 Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.

 More and more areas of the state are special control areas due to population increases.

 EPA’s adoption of a new PM2.5 24-hour NAAQS has resulted in 2 nonattainment areas, with a third meeting the definition but not legally designated as such. This proposed rule change will reduce grain loading in all areas and will help prevent future problem.

52) "Emissions unit" means any part or activity of a source that emits or has the potential to emit any regulated air pollutant.

(a) A part of a source is any machine, equipment, raw material, product, or byproduct that produces or emits regulated air pollutants. An activity is any process, operation, action, or reaction (e.g., chemical) at a stationary source that emits regulated air pollutants. Except as described in subsection (d) of this section, parts and activities may be grouped for purposes of defining an emissions unit if the following conditions are met:

(A) The group used to define the emissions unit may not include discrete parts or activities to which a distinct emissions standard applies or for which different compliance demonstration requirements apply; and

(B) The emissions from the emissions unit are quantifiable.

(b) Emissions units may be defined on a pollutant by pollutant basis where applicable.

(c) The term emissions unit is not meant to alter or affect the definition of the term "unit" under Title IV of the FCAA.

(d) Parts and activities cannot be grouped for determining emissions increases from an emissions unit under OAR 340-224-0050 through 340-224-0070, or 340 division 210, or for determining the applicability of any New Source Performance Standard (NSPS).

Delete definition of “collection efficiency” and define “control efficiency,” “capture efficiency,” “destruction efficiency,” and “removal efficiency”

Clarification. There has been confusion among the terms “capture efficiency,” “collection efficiency,” “removal efficiency,” and “control efficiency.” “Collection efficiency” is the only term currently defined in divisions 236 and 240. “Removal efficiency” is replacing “collection efficiency.” The definitions of “capture efficiency,” “destruction efficiency,” and “control efficiency” are being added to help clarify the differences among the terms.

 

To demonstrate compliance with a removal efficiency requirement, testing the inlet/outlet of a control device on an air conveying system would be very difficult.  Usually, there is not enough room (straight duct) to measure the inlet and the flow is cyclonic.  Therefore, DEQ is changing the requirement to a “rated removal efficiency” which should be available from the manufacturer of the equipment. Required operation and maintenance plans will ensure proper operation of any air pollution control devices.

Repeal rules

Repeal spray paint rules since there are now equivalent federal rules. There is no air quality impact because there are now equivalently protective federal rules. There would be a slight positive fiscal impact because the paint manufacturers would no longer need to certify to two different but environmentally equivalent standards and Title V sources would no longer need to certify compliance with the Oregon rule. While these rules were adopted as part of the Portland ozone plan, the immediate issue is really Title V permit streamlining.
