### NOTICE OF INTENT TO AMEND A STATE PLAN REGARDING PARTICULATE MATTER (PM-10) AIR QUALITY IMPROVEMENT IN THE SANDPOINT NONATTAINMENT AREA AND PINEHURST NONATTAINMENT AREA

Notice is hereby given that the State of Idaho Department of Health and Welfare, Division of Environmental Quality (DEQ) has scheduled a public comment period from June 10 to July 11, 1995 and will conduct a public hearing on July 10, 1995 at 7:00p.m. in the Lake City Senior Center, 1916 Lakewood Drive, Coeur d'Alene. The purpose of the hearing and comment period is to receive comments from the public on revising Chapter VIII of the Implementation Plan for the Control of Air Pollution in the State of Idaho, Sandpoint PM-10 Air Quality Improvement Plan and Pinehurst PM-10 Air Quality Improvement Plan, to include contingency measures as required by the federal Clean Air Act (CAA). The contingency measures provide for additional emission reductions when applicable under the CAA provisions. The air quality improvement plans identify residential wood burning and fugitive road dust as the primary sources of PM-10 pollution. The Sandpoint plan also identifies industrial sources as primary sources of PM-10 pollution. These sources have contributed to violations of the state and federal ambient air quality standards for PM-10. In the Sandpoint and Pinehurst plans, the contingency measures will reduce emissions from residential wood burning through various control measures. A mandatory wood burning curtailment program is the contingency measure in the Sandpoint area. Overcontrol ofwood burning emissions through replacement programs, voluntary curtailment, and otherprograms constitutes the contingency measure in Pinehurst. These plan revisions demonstrate that implementation of additional control measures will further improve air quality to meet the ambient air quality standard for PM-10 as well as maintain the ambient standard into the future. Written comments and data concerning this action are encouraged and will be accepted by DEQ until5:00 P.M., MST July 11, 1995. Comments transmitted by facsimile will be accepted up to the deadline. Written comments will be received at the following address:

### Public Comment Period for the Revised Contingency Measures in the Sandpoint and Pinehurst Particulate Matter (PM10) 

### Air Quality Improvement Plans

PUBLIC HEARING STATEMENT Ms. Hearing Officer, Ladies and Gentleman, my name is Ed Tulloch. I am the Monitoring and Technical Support Supervisor with the Idaho Department of Health and Welfare, Division of Environmental Quality for the North Idaho Regional Office in Coeur d'Alene. The purpose of the hearing tonight is to receive comments on the revised contingency measures for two PM 10 nonattainment areas; Sandpoint and Pinehurst. My testimony will briefly outline (1) the history of the events which have triggered these revisions, (2) the Department's actions leading to this hearing, and (3) how the Department will respond to the comments received at this hearing.

In July 1987, the U.S. Environmental Protection Agency (EPA) adopted ambient air quality standards for small airborne particles less than or equal to 10 microns in diameter, known as PM 10 • The State of Idaho later adopted these health-based standards. The standard that we are concerned with tonight is the 24-hour standard for particulate matter, PM 10, which is established at 150 micrograms per cubic meter (p,g/m 3). This air quality standard
was set by the EPA to protect human health and provide a margin of safety.

Ambient monitoring conducted by the Department has shown that the Sandpoint and Pinehurst areas have periodically exceeded the 24-hour ambient standard for PM 10 and as a result, these areas were designated as nonattainment areas for PM 10• Maps of the nonattainment boundaries are available in the corresponding documents for each area. When an area is designated nonattainment for one or more of the criteria pollutants identified by the National Ambient Air Quality Standard, the Clean Air Act (CAA) requires that states adopt and submit a state implementation plan to the EPA. A state implementation plan (SIP) must improve air quality in the nonattainment
area by the applicable date set by the Act and also demonstrate that the air quality standard will be maintained into the future under the guidance of the plan. It is the Department's goal to meet all the requirements set forth by the CAA for improving air quality in nonattainment areas while minimizing any associated impact on the local community structure and its economic vitality.

One of the many requirements of the CAA is that SIP's include contingency measures for each area. Contingency measures must provide for additional emission reductions as a safety net to the attainment strategy. The contingency measures must be equivalent to at least 25 percent of the emission reductions required to achieve attainment. To expedite their effectiveness, the CAA requires that the contingency measures are fully adopted by the States and ready to take effect when needed. Some states may decide to build the contingency measures into July 10, 1995

### ', l'the control strategy as overcontrol in that the contingency measures are already in effect, thereby further reducing emissions from the significant sources. This is the approach DEQ has proposed for the Pinehurst and Sandpoint
areas.
The Division of Environmental Quality (DEQ) has conducted several scientific investigations to determine the major sources of PM 10 pollution in each of the nonattainment areas. This comprehensive investigative work, which includes chemical analysis of ambient samples, computerized modeling of source impacts, detailed analysis ofmeteorological conditions and an inventory of sources producing PM 10 emissions, is summarized in the air quality improvement plan for each area. The results from each of the investigative techniques were evaluated and used by DEQ to identify the major sources causing the air quality problems in the Sandpoint and Pinehurst areas. A comprehensive control strategy for each area was developed based on these source impacts. The contingency
measures are part of the comprehensive emission reduction strategies designed for the two locations.

In the Sandpoint and Pinehurst plans, the contingency measures will reduce emissions from residential wood burning through various control measures. A mandatory wood burning curtailment program is the contingency
measure in the Sandpoint area. Overcontrol of wood burning emissions through replacement programs, voluntary curtailment, and other programs constitutes the contingency measure in Pinehurst. The attainment plans for each
area demonstrate that implementation of additional control measures will further improve air quality to meet the ambient air quality standard for PM-10 as well as maintain the ambient standard into the future.

The Department is very interested in receiving comments from the public on the revised contingency
measures. No one should feel that they must have detailed technical knowledge of the plan in order to provide useful comments. Many of the rules and plans developed by the Department are modified prior to final issuance because of significant comments by concerned citizens. The Department takes public input very seriously and your comments are always appreciated.

Oral comments presented at this hearing, or written comments mailed to the Department are welcome. Following this hearing, and after receiving the Hearing Officers' report and public comments, the Department will review all the comments, make the appropriate revisions and prepare a final document for inclusion in the State Implementation Plan for air quality. The adopted contingency measures will then be submitted to the Environmental Protection Agency for its consideration.

The public comment period closes on July 11, 1995. To be considered, all written comments submitted to DEQ must be received no later than 5:00 P.M.,MST, July 11, 1995. Comments submitted by facsimile (FAX)

### V. CONTROL STRATEGY DEVELOPMENT D. CONTINGENCY MEASURES 

### The Clean Air Act, as amended under section 172(c)(9), requires that all moderate nonattainment area SIP's that demonstrate attainment include contingency measures. Contingency measures must provide for additional emission reductions beyond the control strategy that is required to attain the ambient standard. According to the General Preamble, contingency measures may go beyond RACM and must be equivalent to 25 percent of the emission reductions required to achieve attainment. The contingency measures must be fully adopted and take effect within one year without further legislative action once EPA makes a determination of the area not meeting the required deadlines. These deadlines include attainment of the standard by the applicable date and reasonable further progress milestones. EPA has provided guidance that emission reductions resulting from overcontrol in the attainment strategy will be accepted as contingency measures. The Sandpoint Area attainment strategy will use overcontrol as the method to meet the contingency requirements. Emission reductions resulting from overcontrol are achieved primarily by the mandatory residential wood burning curtailment program adopted by the City of Sandpoint in February 1995. This ordinance increases the effectiveness of the episodic wood burning curtailment program by incorporating a mandatory component into the program. A copy of the city ordinance is attached. Originally, the attainment strategy required a voluntary program only. The city ordinance implements an episodic curtailment program that combines a voluntary phase with a mandatory phase that is enforced by the City. A voluntary phase is used during the initial stage of a wintertime episode; if the voluntary phase does not prevent further increases in PM 10 

### concentrations, than a mandatory phase becomes effective. The trigger level for the mandatory phase is 100 p.g/m 3 

### on a running 24-hour average. The ordinance provides exemptions for sole source homeowners, low-income households and certified stove users. The attached ordinance describes the program in greater detail. DEQ conducted additional modeling analysis to evaluate the impact of the emission reductions resulting from the mandatory program. The dispersion modeling results, which included the emission reductions resulting from overcontrol, demonstrated lower ambient concentrations, i.e. less than 150 p,g/m3
, 

### that satisfy the 25 percent contingency requirement. A brief discussion of the modeling results and contingency evaluation is provided below. The mandatory episodic curtailment program as a contingency measure is further

### complemented by the other existing control measures which include fugitive road dust reduction programs, industrial operating permits, and the wood stove buy-out program. The control strategy, which includes these existing control measures, demonstrates attainment of the PM10 

### standard in Sandpoint. 

### Contingency Analysis DEQ conducted additional modeling analyses to evaluate the effectiveness of the mandatory curtailment program and other control measures. The modeling analysis predicted a maximum 24-hour PM 10 

### concentration of 196 p,g/m 3 

### for 1994 with no controls in place. This analysis of the uncontrolled emissions provided information to determine a design value which corresponds well with maximum wintertime concentrations measured in the Sandpoint area. The control strategy with a mandatory curtailment program will reduce the maximum PM10 

### concentration to 133 p,g/m3• 

### This represents a 63 p,g/m3

### (150 p,g/m3)

### concentration value with control measures in place (133 p,g/m3),

## IV. CONTROL STRATEGY DEVELOPl\1ENT C. CONTINGENCY MEASURES

- (1995 REVISION) The Clean Air Act, as amended under section 172(c)(9), requires that all moderate nonattainment area SIP's that demonstrate attainment include contingency measures. Contingency measures must provide for additional emission reductions beyond the control strategy that is required to attain the ambient standard. According to the General Preamble, contingency measures may go beyond RACM and must be equivalent to 25 percent of the emission reductions required to achieve attainment. The contingency measures must be fully adopted and take effect within one year without further legislative action once EPA makes a determination of the area not meeting the required deadlines. These deadlines include attainment ofthe standard by the applicable date and reasonable further progress milestones. The EPA has provided guidance that emission reduction resulting from overcontrol in the attainment strategy will be accepted as contingency measures. The Pinehurst area SIP will use overcontrol as the method to meet the contingency requirements. Emission reductions resulting from overcontrol in the attainment strategy are achieved primarily from the residential wood burning program which includes: wood stove replacement, voluntary wood stove curtailment, public awareness and home weatherization. New data collected in 1994 showed significant changes in the number of woodstoves operating in the Pinehurst area as compared to the 1990 survey. The Washington Water Power Company conducted a mail survey in May 1994 to gain updated information on woodstove use in the area (see appendix F for new attachment). The information was also used to determine the interest level of area homeowners to participate in a wood stove replacement program. The new data suggests that the population of wood burning devices in the Pinehurst area is lower than the earlier projections which were based on the 1991 survey data (see appendix F). 

### The population of wood burning devices in the Pinehurst area is summarized ·in Table IV

### -3. This information was submitted to the EPA in June 1994 at their request as part of the fmal approval for the 1992 Pinehurst SIP attainment strategy. Although this new data indicates that the existing attainment strategy provides for sufficient emission reductions, additional emission reductions from other significant sources such as fugitive road dust are beneficial. Fugitive road dust controls are potentially necessary in the Pinehurst area to compensate for continued residential growth in this airshed. Since no additional ordinances are planned by the local governments to restrict the

### availability and installation of uncertified wood burning devices, control measures that reduce emissions from road dust are strongly encouraged. Such control measures will assist with reducing the baseline ambient concentration of PM10 

### and therefore further assist the eposidic control measures with reducing elevated wintertime PM 10 

### concentrations. Overcontrol Analysis Original analysis, using U.S. Environmental Protection Agency (EPA) approved methods, determined that the attainment strategy (based on information from the 1991 survey) would result in overcontrol equal to 16 percent. As mentioned earlier, EPA guidelines recommend contingency measures should equal 25 percent of attainment strategy. Therefore, the EPA requested that DEQ submit additional contingency measures to make up the difference. The rollback analysis presented in Section III established an attainment emission level (150 p..g/m3) 

### equal to 393 lbs./day. Without any control measures in place, such as a voluntary residential wood burning curtailment program or public awareness, the 1994 emission inventory predicted 485 lbs./day of PM 10 

### from the sources in the Pinehurst area. With controls in place to remove and reduce sources of PM10, 

### primarily from uncertified woodstoves, the PM 10 

### emissions for 1994 were calculated at 309 lbs/day. This calculation was based on the revised emission inventory which incorporated the Washington Water Power data updating the wood burning population in the Pinehurst area. The control strategy represents a reduction of 176 lbs./day of PM10 

### emissions from this airshed. Overcontrol is defined as the difference between the 24-hour NAAQS for PM 10 

### (150 p..g/m3 = 

### 393 lbs./day) and the maximum controlled ambient concentration. In Pinehurst, proportional rollback modeling was used to demonstrate attainment. This approach establishes a direct proportionality between PM 10 

### emissions and ambient PM 10 

### concentrations. Thus, reducing· emissions to less than 393 lbs./day would result in overcontrol and ambient concentrations below the standard. The reduction of 176 lbs./day results in overcontrol of approximately 48 percent, which is considerably more than the minimum EPA requirement for contingency.

# What is PM10

# ?

Particulates (small fine particles) can be a pollution problem and impair human health and comfort, climate, visibility, and vegetation. Effects ofparticulates on human health are directly related to their chemical composition and size. Small particles, referred to as PM 10 

### (particulate matter less than or equal to 10 microns in diameter or approximately 10 times smaller than the diameter of a human hair), are of greatest concern because they enter the body through the nose and mouth, and can go deep into the lungs.
PM 10 

### can cause breathing problems, lung tissue damage, even cancer, and aggravate existing lung and heart diseases. People most sensitive to the effects of PM 10 

### are children, the elderly smokers, and those with respiratory or heart diseases. Particulates pose a threat to human health for the following reasons:

• They may interfere with the respiratory tract;

• They may be toxic;

• They may carry toxic substances into the lungs. The Federal standard for PM 10 

### is expressed in two ways: a 24 hour average and an annual average. The 24-hour standard is 150 micrograms per cubic meter of air. The annual standard is 50 micrograms per cubic meter of air.

Department of Health and Welfare Division of Environmental Quality c:\

...\sip\facts 1 

# A community may exceed the 24-hour standard once a year. If 

### it exceeds the standard more often, it is considered out of compliance with the standard and becomes a 

### non-attainment area. Values that exceed this standard have been measured more than once a year in the Sandpoint area. Because the standards have been exceeded a number of times, so Sandpoint and the surrounding area have been designated a non-attainment area. As a result, the federal Clean Air Act requires an air quality or 

### State Implementation Plan

-- known as a SIP

-- to improve air quality as soon as possible to meet national clean air standards. A SIP:

• May call for air-pollution controls on industrial facilities, wood stoves, road dust, agricultural practices, or any other significant source of. PM 10 

### air pollution;

• Outlines programs to reduce air pollution levels and assigns local, state and federal government agencies to carry them out;

• Proposes timelines for each implementation activity, estimates cost, and identifies where money can be found to do the work.

# Where Does PM10 

# Come From?

PM 10, 

### by definition, are microscopic particles in solid or liquid form, other than water, equal to or less than 10 microns in diameter. These particles are small enough to pass through the upper respiratory system and enter into the lungs. Pollutants entering into the lungs can affect breathing, and toxic chemicals can be absorbed directly into the blood.


## Common Sources of PM 10 : 

### 1) 

## Combustion Processes-- smoke

.,. industrial boilers, wigwam burners, woodstoves, slash burning, agricultural burning, automobiles, diesel trucks.
2) 

## Mechanical Processes

-- dust

.,. fugitive dust from paved and unpaved roads, rock crushing, agricultural tilling, construction activity, wind-blown erosion.
3) 

## Chemical Processes-- secondary aerosols

.,. smelters, chemical plants (fertilizer), power plants (coal/natural gas), dry kilns, automobiles, and other sources of gaseous pollutants.
