6 200 Add a definition of “area violating the NAAQS” This is for areas that have not yet been designated NAA. See discussion below in the applicability section of Division 224.  
11 200 Definition of categorically insignificant activities Update list  
12 200 Change definition of categorically insignificant activities regarding emergency generators We need a permitting category for these facilities as synthetic minor permits. We need to change the list of categorically insignificant RULE CHANGE. If there was an emergency, these generators would run as long as necessary and would trigger SERs. They could not pass the 1-hour NO2 and SO2 standards but would we have different requirements for emergencies? What does Washington do for these sources? Mark asked that this topic be on the agenda for the Bellingham meeting.

14 (uu) Emergency generators and pumps used only during loss of primary equipment or utility service due to circumstances beyond the reasonable control of the owner or operator, or to address a power emergency as determined by the Department;

19 200 Change the definition of "Continuous Monitoring Systems" to EXCLUDE the Department's Continuous Monitoring Manual DEQ has repealed Continuous Monitoring Manual and instead will use the requirements of EPA’s ______________  
28 200 Unless otherwise specified by rule, opacity shall be measured in accordance with EPA Method 9 or a continuous opacity monitoring system (COMS) installed and operated in accordance with the Department's Continuous Monitoring Manual. For all standards, the minimum observation period shall 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 equal or exceed the opacity percentage in the standard, whether or not the readings are consecutive. Continuous Monitoring Manual repealed?  
30 200 "Particulate Matter" means all finely divided solid or liquid material, other than uncombined water, emitted to the ambient air. When used in emission standards, particulate matter is defined by the method specified within the standard or by an applicable reference method in accordance with OAR 340-212-0120 and 340-212-0140. Unless otherwise specified, sources with exhaust gases at or near ambient conditions may be tested with DEQ Method 5 or DEQ Method 8, as approved by the Department. Direct heat transfer sources shall be tested with DEQ Method 7; indirect heat transfer combustion sources and all other non-fugitive emissions sources not listed above shall be tested with DEQ Method 5. Include test methods with limit in specific rules? Or leave in definition? See PM2.5  
32 200 "PM10 ": Source Sampling Manual repealed?  Do the standards in other divisions need to include the test method instead of having it here in the definition?
33 (a) When used in the context of emissions, means finely divided solid or liquid material, including condensable particulate, other than uncombined water, with an aerodynamic diameter less than or equal to a nominal 10 micrometers, emitted to the ambient air as measured by an applicable reference method in accordance with the Department's Source Sampling Manual(January, 1992);  
36 200 Definition of “significant air quality impact” The threshold concentrations listed in Table 1 are used for comparison against the ambient air quality standard and do not apply for protecting PSD Class I increments or air quality related values (including visibility). For sources of VOC or NOx, a major source or major modification has a significant impact if it is located within the Ozone Precursor Distance defined in OAR 340-225-0020. CLARIFY? OR MOVE?

69 208 Visible Emissions and Nuisance Requirements    
73 208 Definition of fuel burning equipment different from Division 228 and 240 Change definition of fuel burning equipment to “external combustion device,” delete from Divisions 208, 228, and 240, move to Division 200. Avoids confusion about indirect heat transfer (e.g., boilers), direct heat transfer (e.g., dryers), and internal combustion devices (e.g., gas turbines).  
80 208 Exempt fugitive sources from opacity limits Fugitive emission sources are regulated in 0200-0120  
81 208 Exempt sources subject to source specific standards in other Divisions, Incinerator Regulations (division 230), VOC Point Sources (division 232), Wood Products (Division 234), Specific Industries (division 236), NSPS (division 238), Areas with Unique Air Quality Needs (division 240) or NESHAP (division 244). Specific standards, such as New Source Performance Standards (NSPS) and National Emission Standard for Hazardous Air Pollutants are specifically written for certain industries. These rules are more stringent than the general permitting requirements. If the source specific rule does not have a standard for the same pollutant (opacity, particulate matter or sulfur dioxide), the general standards will still apply. By applying only the industry specific standards, the Department will eliminate confusion and streamline permitting requirements. To address the stringency issue, a requirement that any source exempt from 208-0110 must have a startup/shutdown plan in accordance with 340-314-0340 has been added. This would be equivalent to existing practices in which we exercise enforcement discretion for excess emissions during startup/shutdown. we’d have to be careful with grain loading since our grain loading is based on DEQ 5 while the NSPS and NESHAPs are based on EPA 5, and I’m sure there are all sorts of reasons why we can’t do this, but it would be nice to consider it.  
82 208 Delete 40% opacity limit DEQ is proposing the change because of the following reasons:  
83 ·        Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT. [DOES THIS ALSO APPLY TO OPACITY OR JUST GRAIN LOADING?]  
84 ·        Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.  
85 ·        More and more areas of the state are special control areas due to population increases.  
86 ·        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, especially in light of EPA’s plan to reduce the PM2.5 NAAQS even further.  
87 ·        Phased compliance will give sources that cannot meet the new standards time to comply.  
88 a.      The 40% opacity limit applies to grandfathered sources that are over 30 years old. These sources should have been modified or replaced by now.  
89 2.      Regulatory streamlining (Executive Order Number EO-03-01):  
90 Permitting: Changes would make it easier to write permits because fewer standards would have to be included in the permits. In addition, multiple standards would not apply to a single piece of equipment or process.  
91 Compliance: Making the requirements clearer, will make it easier to determine compliance for the both the source and the DEQ. Eliminating 40% opacity limit will provide equity for the sources.  
92 3.      Rule Fix options:  
93 a.      Delete the 40% grain loading limit.  
94 b.      Make the 20% grain loading limit applicable only to stationary sources that do not have source specific standards.  
95 208 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:  
96 ·        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.  
97 ·        Other reasons for changing to a 6 minute average include:  
98 o   A reference compliance method has not been developed for the 3 minute standard.  
99 o   EPA method 9 results are reported as 6-minute averages.  
100 o   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.  
101 o   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 the Department’s policy that the inspector observes the source for at least 6 minutes before making a compliance determination.  
102 208 Move 20% opacity limit for 30 seconds in an hour from division 208-0510 since these rules are being repealed    
103 208 Add a provision for maintenance for wood-fired boilers and process heaters installed before 1970 Visible emissions during grate cleaning are greater than 20% opacity. Since the 40% opacity limit is being eliminated, a provision for grate cleaning and other maintenance is needed.  
104 208 Add a provision that non-fugitive emissions units exempt from this rule must have a startup/shutdown procedures Non-fugitive emission units that are subject to source specific rules in other Divisions, as well as the NSPS and NESHAP, must have startup/shutdown procedures approved because these rules do not apply during startup/shutdown.  
105 208 Add a test method A test method should always be specified with each standard in order to be able to show compliance  
106 208 add a compliance date for existing sources.    
107    
108 208 Make the fugitive emission requirements applicable statewide to replace the opacity standards. Fugitive emissions should be controlled statewide  
109 208 Since the opacity standards will not apply to fugitive emission sources, work practice standards will be used instead to abate fugitive emissions. The Department has clarified that fugitive emissions must be abated upon order, rather than the subjective determination of a nuisance or trying to read opacity to comply with an opacity limit.  
110 208 Add a definition for particulate fugitive emissions This clarifies what fugitive emissions entail  
111 208 Add EPA Method 22 as the reference method A test method should always be specified with each standard in order to be able to show compliance  
112 208 Add requirement for fugitive emission control plan This requirement will help address issues if fugitive emissions escape the property boundary  
113 208 Eliminate this requirement prohibiting masking emissions. Why? – ESCO – nuisance. Health, safety, welfare…in CFR also. Later?  
115 208 Eliminate all of these special requirements for the Portland area Apply only in Clackamas, Columbia, Multnomah and Washington counties. DEQ proposes to repeal OAR 340-208-0550 through 630 because these rules have limited applicability and because other rules make this rule largely redundant except for the 20% opacity limit for 30 seconds in an hour.  
116 208 In Division 208 are the rules that apply in Multnomah, Columbia, Clackamas and Washington counties, with a different opacity standard for non-fuel burning equipment. However, in 208-0510, it says these rules don’t apply to activities for which specific industrial standards have been adopted. See rule citation at the end of the email. If we exempt sources from the general standards (opacity and grain loading) if there are specific standards, do those specific standards have to have an opacity and grain loading part???  
117        
118 First, note the list of divisions with specific industrial standards includes division 238 (New Source Performance Standards). Also note that division 244 (NESHAPs) is not included. I think to be consistent, division 244 should be added to the list. To be honest, I think we should get rid of these 4-county rules altogether, but I’ve given up on that.  
119 340-208-0510 Exclusions  
120 (1) The requirements contained in OAR 340-208-0510 through 340-208-0610 apply to all activities conducted in Clackamas, Columbia, Multnomah, and Washington Counties, other than those for which specific industrial standards have been adopted (divisions 230, 234, 236, and 238), and except for the reduction of animal matter, 340-236-0310(1) and (2).  
123 210 Add requirement that changes that are subject to NESHAP or NSPS should not be included as Type 1 changes Corrects a problem regarding the distinctions between the Type 1 and Type 2 changes. A project that qualifies as a Type 1 change gets default approval to proceed 10 days after receipt of the application.  There have been instances when companies have replaced a NESHAP subject chrome plating line (or lines) with entirely new equipment or have replaced the respective control devices.  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 there is insufficient time to respond to the applicant.  Sixty days should be allowed under the Type 2 criteria for such reviews.  With all of the new area source NESHAP permits, there may be many more similar scenarios.  Change the rule language to bump such changes into the Type 2 category to allow for adequate review time.  
124 210 List requirements for Type 2 changes rather than reference changes in 0225(1) Clarification  
126 212 Stationary Source Testing and Monitoring ·        Update Source Sampling Manual  
127 ·        Update Continuous Monitoring Manual  
129 212       MARK B: I believe the manuals provide necessary guidance on how to do the testing/monitoring and what is expected (test plan requirements, report requirements, monitoring QA/QC, etc.).  Having the manuals referenced in rule is difficult to maintenance when the manual needs to be updated on a regular basis (that is why it hasn’t been updated).  However, how do we specify the DEQ method in rule without referencing the manual?  Also, since EPA methods & monitoring requirements change, would an existing permittee need to revise their monitoring plan every time EPA edits their requirements, or would they be grandfathered?  
130       MARK F: My thinking is that we had language similar to 60.8 to Divisions 212.  That will specify the procedures and provide reference to the methods.  
132   SSM and CMM We really only have 2 unique test methods in Oregon. They are the wet bulb/dry bulb method for measuring stack moisture and the high volume particulate matter test. DEQ methods 5 and 7 are somewhat unique, but we could rely on EPA Method 5 and 202. For all other test methods, we rely on EPA reference methods. I wonder if we couldn't just add some of the general provisions from the Source Sampling Manual to Division 212 and incorporate 40 CFR 60.8 and appendices by reference. We could retain the 1992 Source Sampling specifically for the methods I cited above without having to revise the document and updating the SIP. The changes to Division 212 could be made any time that we are doing a SIP revision.  
133   For monitoring, I think we could incorporate Parts 60 and 75 into Division 212 by reference and do away with the Continuous Monitoring Manual altogether. SEE 07/23/10 EMAIL FROM MSF  
138 216 Air Contaminant Discharge Permits Get rid of list of permitted sources and use generic catch-all categories (i.e., > XX tons/year, subject to XX, etc.). Some sources on list don’t need permits [Cory].  
139 [Table 1 and Table 2]  
143 216 Add a requirement to keep a copy of the permit onsite Having the permit on site and monitoring and record-keeping conditions all exist to ensure the permittee is meeting the “rules and standards adopted by the Commission.”  
144 218 Oregon Title V Operating Permits    
147 218 Add a requirement to keep a copy of the permit onsite Having the permit on site and monitoring and record-keeping conditions all exist to ensure the permittee is meeting the “rules and standards adopted by the Commission.”  
148 218 Title V General Permits Do we need this?  
150 222 Stationary Source Plant Site Emission Limits    
151 222 Replace the list of division 244 tables with division 244 This will simplify the rule  
152 222 Exclude toxic air pollutants in division 246 other than those listed in the SER table This is consistent with the netting basis.  
154 222 Move rules about establishing the baseline emission rate from the definition to the PSEL rule This will move procedural requirements from the definitions  
155 222 Move rules about establishing the netting basis from the definition to the PSEL rule This will move procedural requirements from the definitions  
156 222 Add a provision for making corrections to the PM10 netting due to better emissions information should be made before establishing the PM2.5 netting basis. The rules did not specify what the process should be for setting the PM2.5 netting basis and PSEL if corrections are needed in the PM10 netting basis and PSEL.  
157 222 Add a provision for when the PM 2.5 true-up does not apply and the PM2.5 PSEL is greater than the PM2.5 netting basis by more than the significant emission rate of 10 tons/year, DEQ shall determine whether:    
158 ·        the PM2.5 emissions correction would not have a material impact on air quality, or    
159 ·        the source is willing to commit to enforceable conditions (i.e., offsets from other point sources, offsets from area sources such as woodstove change-outs, etc.) to ensure that the PM2.5 emissions correction would not have a material impact on air quality.    
160 222 Add language to clarify that the source specific PSEL being set equivalent to the generic PSEL does not make it a generic PSEL. Clarification  
161 222 Add the provision for establishing the source specific annual PSEL for PM2.5 that was in the netting basis definition. This will move procedural requirements from the definitions  
162 222 Add the provision for determining when a major modification is triggered that was in the major modification definition. This will move procedural requirements from the definitions  
163 222 Fix PSEL rules for Modeling?    
164 222 Add reference to division 224 for NSR This is a clarification and consistent with other rules.  
165 222 Fix baby-Tek The question of a different SIC needs to be addressed. If you split a source into 2 separate sources, those two sources can have different SICs. If you are splitting up a source, they need to retain their SIC. The netting basis protects the airshed. If the source is grandfathered, then they wouldn’t have to do an AQ analysis. If they are a new source, then they trigger NSR/PSD and everything else. When Tektronix split up, they sources had the same SIC. There was a single transfer of netting basis to Maxim. The other “babies” were treated as new sources. RULE CHANGE/DAVE BRAY  
167 224 Major New Source Review    
168 224 Add an applicability section for 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 “areas violating federal NAAQS” 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.  
170 224 “Areas violating federal NAAQS” but not designated nonattainment There are areas that violate the NAAQS but have not yet been designated nonattainment by EPA.  See explanation above in the applicability section. Sources will be required to install LAER, provide offsets and demonstrate that a net air quality benefit will be achieved.  
171    
172 ANDY: One concern I have is this: most of the emissions causing NAAQS violations are from area and mobile sources, but this would focus only on point sources.  It is a good tool for nonattainment areas – even when point sources aren’t a major cause of the violations – because it gets industry support for developing an attainment plan.  But that only works if the requirement is mandated by federal law.  If we require it, even in cases where point sources really aren’t significant, it could have the opposite effect.  
173    
174 I would think we would not want it to be fully automatic, but rather only trigger if there is some AQ analysis that shows it would be helpful.  So, perhaps a source over the SER would have to put on technology (either LAER or BACT), and then do an AQ analysis to see if it would cause a significant impact in the areas of violation.  If so, the source would have to do more controls or get an offset.  We also have to remember that these sources would also be subject to PSD if they are over 250 tons, so the requirements would have to nestle within that.  Something like that might be more supportable since we could say it is actually needed to protect air quality (as opposed to automatic requirements that might affect a new source well downwind of the area of violation).  
175    
177 224/225 Incentives for GHG offsets from sources that we don’t normally regulate to avoid PSD. A major source should be able to use other projects, such as improvements in agricultural activities, to offset GHG emissions from point sources.  Technology (BACT) requirements may not be meaningful for some point sources, but offsets could be very meaningful.    
178 225 Air Quality Analysis Requirements    
179 225 Add Division 204 as another division that has definitions that would apply to this division Add reference to Division 204 definitions  
180 225 “Areas violating federal NAAQS” but not designated nonattainment    
181 225 Background light extinction not used in this division    
182 225 Move definition of “predicted Maintenance Area Concentration” This definition is not in alphabetic order  
183 225 Delete annual average maintenance area concentrations EPA revoked the annual PM10 standard, because available evidence does not suggest a link between long-term exposure to PM10 and health problems.  
184 225 Add “or area violating the ozone NAAQS” to the definition of ozone precursor distance There are areas that violate the NAAQS but have not yet been designated nonattainment by EPA.  See explanation above in the applicability section.  
185 225 Add “or area violating the ozone NAAQS” to the definition of ozone precursor offsets There are areas that violate the NAAQS but have not yet been designated nonattainment by EPA.  See explanation above in the definition of “area violating the NAAQS.”  
186 225 Repeal procedural requirements The requirements in this rule are not complete. A complete list is included in the modeling protocol that is written by the source or sometimes by DEQ staff.  
188 225 Provide an option of using another impact model in PSD Class II and III areas Allows sources to propose use of another model based on approval by DEQ and EPA  
190 25 Add times to the end of the sentence “for all averaging” Correction  
194 225 Net air quality benefit analysis Current procedure is too restrictive.  Consider additional offsets. Check with Mark Bailey do we want to do this now or with overhaul??  
196 225 Add SO2 and NOx offsets for non-ozone areas This offset ratios are based the presumptive levels established by EPA in the preamble to Significant Impact Levels (SILs)  
197 225 Add SO2 and NOx offsets This offset ratios are based the presumptive levels established by EPA in the preamble to Significant Impact Levels (SILs)  
198 225 Add NOx offsets This makes the rule language consistent with EPA requirements in 40 CFR Part 51 and past implementation of the rule.  
199         For the AQRVs of visibility and deposition in the Gorge, the thresholds are the same as for Class I areas, which are visibility impact of 0.5 decivew (5% extinction), and Deposition Analysis Thresholds (DATs) for S or N of 0.005 kg/ha/yr.  In addition, a qualitative assessment of O3 impacts is also made.  As I mentioned earlier, the analysis of AQRV impacts in the Gorge for PSD/NSR projects has been done on an “as requested basis for informational purposes,” not on an “as required” basis.  To my knowledge this request as never been refused, although there have been cases of some resistance to the request.  In my view there is an advantage to the facility and DEQ of having this analysis done  as part of the AQ modeling and permit application process as the issue will surely be raised during the public hearing and public comment period. [PHIL]  
200 226 General Emission Standards    
201 [Table 1-Particulate Matter Emissions Standards for Process Equipment]    
207 226 Change Fuel Burning Equipment to External Combustion Devices Change definition of fuel burning equipment to “external combustion device.” Avoids confusion about indirect heat transfer (e.g., boilers), direct heat transfer (e.g., dryers), and internal combustion devices (e.g., gas turbines).  
208 226 Exempt sources subject to source specific standards in other Divisions, Incinerator Regulations (division 230), VOC Point Sources (division 232), Wood Products (Division 234), Specific Industries (division 236), NSPS (division 238), Areas with Unique Air Quality Needs (division 240) or NESHAP (division 244). Specific standards, such as New Source Performance Standards (NSPS) and National Emission Standard for Hazardous Air Pollutants are specifically written for certain industries. These rules are more stringent than the general permitting requirements. If the source specific rule does not have a standard for the same pollutant (opacity, particulate matter or sulfur dioxide), the general standards will still apply. By applying only the industry specific standards, the Department will eliminate confusion and streamline permitting requirements. To address the stringency issue, a requirement that any source exempt from 208-0110 must have a startup/shutdown plan in accordance with 340-314-0340 has been added. This would be equivalent to existing practices in which we exercise enforcement discretion for excess emissions during startup/shutdown. we’d have to be careful with grain loading since our grain loading is based on DEQ 5 while the NSPS and NESHAPs are based on EPA 5, and I’m sure there are all sorts of reasons why we can’t do this, but it would be nice to consider it.  
209 226 Delete 0.2 gr/dscf limit and add a compliance date for existing sources. DEQ is proposing the change because of the following reasons:  
210 ·        Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT.  
211 ·        Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.  
212 ·        More and more areas of the state are special control areas due to population increases.  
213 ·        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, especially in light of EPA’s plan to reduce the PM2.5 NAAQS even further.  
214 ·        Phased compliance will give sources that cannot meet the new standards time to comply.  
215 The 0.2 grain loading limit applies to grandfathered sources that are over 30 years old. These sources should have been modified or replaced by now.  
216 4.      Regulatory streamlining (Executive Order Number EO-03-01):  
217 Permitting: Changes would make it easier to write permits because fewer standards would have to be included in the permits. In addition, multiple standards would not apply to a single piece of equipment or process.  
218 Compliance: Making the requirements clearer, will make it easier to determine compliance for the both the source and the DEQ. Eliminating the 0.2 grain loading limit will provide equity for the sources.  
219 5.      Rule Fix options:  
220 a.      Delete the 0.2 grain loading limit.  
221 b.      Make the 0.1 grain loading limit applicable only to stationary sources that do not have source specific standards.  
222 Second, I wonder if the general statewide opacity and grain loading standards can have similar language added to them, so that we can leave out the general standards when there is a more stringent industry-specific standard. I guess we’d have to be careful with grain loading since our grain loading is based on DEQ 5 while the NSPS and NESHAPs are based on EPA 5, and I’m sure there are all sorts of reasons why we can’t do this, but it would be nice to consider it.  
223 226 Change 0.2 gr/dscf and 0.1 gr/dscf to 0.20 and 0.10 and add compliance schedule This change is based on 06/06/90 EPA guidance and also to help meet the new PM2.5 ambient air quality standard.  
224 226 Correcting to 12% CO2 for non fuel burning equipment that is burning fuel Division 228 has emission limits for fuel burning equipment but does not apply in this situation. Division 226 applies here if the source is burning fuel. The correction for 12% CO2 makes them fail. The correction is for a controlled combustion device that does not use excess air. No dryer could pass with the correction. RULE CHANGE  
225 228 Requirements For Fuel Burning Equipment and Fuel Sulfur Content    
239 228 Exempt sources subject to source specific standards in other Divisions, Incinerator Regulations (division 230), VOC Point Sources (division 232), Wood Products (Division 234), Specific Industries (division 236), NSPS (division 238), Areas with Unique Air Quality Needs (division 240) or NESHAP (division 244).

241 228 Add a provision that emissions units exempt from this rule must have a startup/shutdown procedures Emission units that are subject to source specific rules in other divisions, as well as the NSPS and NESHAP, must have startup/shutdown procedures approved because these rules do not apply during startup/shutdown  
242 228 Exempt sources subject to source specific standards in other Divisions, Incinerator Regulations (division 230), VOC Point Sources (division 232), Wood Products (Division 234), Specific Industries (division 236), NSPS (division 238), Areas with Unique Air Quality Needs (division 240) or NESHAP (division 244).

To address the stringency issue, a requirement that any source exempt from 208-0110 must have a startup/shutdown plan in accordance with 340-314-0340 has been added. This would be equivalent to existing practices in which we exercise enforcement discretion for excess emissions during startup/shutdown. we’d have to be careful with grain loading since our grain loading is based on DEQ 5 while the NSPS and NESHAPs are based on EPA 5, and I’m sure there are all sorts of reasons why we can’t do this, but it would be nice to consider it.  
244 228 Delete 0.2 gr/dscf limit and add a compliance date for existing sources. DEQ is proposing the change because of the following reasons:  
245 ·        Some of the affected sources will probably have to reduce emissions anyway due to future regulations, such as the Boiler and Industrial furnace MACT.  
246 ·        Having two standards creates an unequal playing field for industry; especially since new sources can be as much as 40 years old.  
247 ·        More and more areas of the state are special control areas due to population increases.  
248 ·        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, especially in light of EPA’s plan to reduce the PM2.5 NAAQS even further.  
249 ·        Phased compliance will give sources that cannot meet the new standards time to comply.  
250 Second, I wonder if the general statewide opacity and grain loading standards can have similar language added to them, so that we can leave out the general standards when there is a more stringent industry-specific standard. I guess we’d have to be careful with grain loading since our grain loading is based on DEQ 5 while the NSPS and NESHAPs are based on EPA 5, and I’m sure there are all sorts of reasons why we can’t do this, but it would be nice to consider it.  
251 228 Change 0.2 and 0.1 gr/dscf limit to 0.20 and 0.10 gr/dscf. This change is based on 06/06/90 EPA guidance and also to help meet the new PM2.5 ambient air quality standard.  
252 228 Correcting to 12% CO2 for non fuel burning equipment that is burning fuel Division 228 has emission limits for fuel burning equipment but does not apply in this situation. Division 226 applies here if the source is burning fuel. The correction for 12% CO2 makes them fail. The correction is for a controlled combustion device that does not use excess air. No dryer could pass with the correction. RULE CHANGE  
254 228 Add test method A test method should always be specified with each standard in order to be able to show compliance  
255 228 Add date for compliance. This change is based on 06/06/90 EPA guidance and also to help meet the new PM2.5 ambient air quality standard.  
256 228 Add a provision that emissions units exempt from this rule must have a startup/shutdown procedures Emission units that are subject to source specific rules in other Divisions, as well as the NSPS and NESHAP, must have startup/shutdown procedures approved because these rules do not apply during startup/shutdown  
277 234 Emission Standards For Wood Products Industries Repeal neutral sulfite semi-chemical pul mill rules; sulfite pulp mill rules; __________  
317 234 Clarify what is meant by 0500(3). Currently this has been interpreted as a maximum hourly mass emission rate limit, but it was interpreted in the past as being a variable emission limit, depending on actual production rates (i.e., a process weight limit). Possibly eliminate the standard altogether and replace it with work practice standards. If retained, add compliance determination methods and averaging time.    
318 234 Review each rule but definitely fix the wood products rules (340-234-0500) to clarify what the lb/MSF limits mean and how compliance is determined. Include the compliance method for all limits.    
319 234 Add the sentence that defines a violation This sentence does not belong in the definition of average operating opacity. It belongs in this subsection with the standard.  
320 234 Incorporate fuel moisture content into rule and add test method Avoids confusion about indirect heat transfer (e.g., boilers), direct heat transfer (e.g., dryers), and internal combustion devices (e.g., gas turbines).  
329 234 Add a rule for Testing and Monitoring A test method should always be specified with each standard in order to be able to show compliance  
330 236 Emission Standards For Specific Industries Repeal primary aluminum and ferronickel rules  
358 236 Delete hot-mix asphalt rules OAR 340-236-0410, Specific Industry Standard for Hot-mix Asphalt Plants  
359 1.      Problem(s):  
360 The rule is outdated and unnecessary and can be replaced with other existing standards or rules.  
361 2.      Regulatory streamlining (Executive Order Number EO-03-01):  
362 Permitting: Elimination of the Process Weight rule will simplify permits.  
363 Compliance: Deleting the Process Weight requirement will make compliance testing somewhat easier for affected sources.  
364 3.      Rule Fix options:  
365 Delete existing rule in its entirety. Other existing rules would apply to asphalt plants directly without need for a special rule.  
366 Alternatively, delete existing language and replace with 2 provisions: (1) facilities that are subject to the NSPS must meet the NSPS requirements; and (2) facilities not subject to (1) must meet the statewide 0.1 (or 0.10) gr/dscf PM standard.  
367 4.      Issues:  
368 Statutory authority -  
369 Stringency (impact on regulated sources) - Little impact on regulated sources, somewhat simpler permit and testing requirements.  
370 Environmental backsliding (impact on environment) - No impact on the environment is expected from this rule change. Hot-mix asphalt plants will continue to operate as they do currently, and emissions will not change.  
371 SIP revision - Appendix 7 (protection of NAAQS and PSD increment)  
372 236 Eliminate different standards for inside and outside of special control areas. All asphalt plants should comply with the requirements, regardless of where they are located.  
373 236 Make all existing asphalt plants comply with the state standards and all new plants comply with the NSPS. Clarifies requirements for existing and new asphalt plants and eliminates redundant/conflicting standards.  
380 240 Rules For Areas With Unique Air Quality Needs    
384 240 Delete definition of charcoal producing plant No longer needed since Charcoal Producing Plant rules are being repealed   Needed for LRAPA???
390 240 Definition of facility different from Division 238 Move to Division 200 but make exception for Division 238 NSPS definition  
401 240 Delete definition of new source Requirements for “old” wood waste boilers were repealed in 12/2004 because the compliance date (12/31/94) had past. All sources must meet the requirements for “new” sources. New sources and existing sources must comply with 340-240-0110(1), 340-240-120 through 250 so the definition of “new source” is no longer necessary.  
404 240 (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. Need to keep 240 definition for now. Will change later when we put compliance method with standards instead of with definition.  
415 240 Add the sentence that defines a violation This sentence does not belong in the definition of average operating opacity. It belongs in this subsection with the standard.  
416 240 Incorporate fuel moisture content into rule and add test method This clarifies the requirement  
419 240 Delete Charcoal Producing Plant rules These sources no longer exist in the state outside of Lane County. If a source did build a new facility, New Source Review/Prevention of Significant Deterioration (requiring a demonstration that emissions would not cause or contribute to a NAAQS or increment violation), New Source Performance Standards and MACT would apply. These rules would be more stringent than the existing rules.  
421 240 Delete requirement for source testing of charcoal producing plant These sources no longer exist in the state outside of Lane County. See reason above.  
422 240 Add (6) to include the source test methods for particulate matter The definition of particulate matter has been moved to Division 200. The test methods are being separated from the definition and included with the standard.  
425 240 Reference the Department’s Source Sampling Manual rather than test methods on file with the Department Add reference to Source Sampling Manual  
426 240 Add other types of sources Do they exist in Lakeview?  
427 242 Rules Applicable to the Portland Area GROWTH ALLOWANCES
