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 of wood burning emissions through replacement programs, voluntary curtailment, and other programs 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 PM10 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 PM10 • 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, PM10, which is established at 150 micrograms per cubic meter (p,g/m3

). 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 PM10 and as a result, these areas were designated as 

nonattainment areas for PM10• 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

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 PM10 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 

of meteorological conditions and an inventory of sources producing PM10 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 PM10 concentrations, than a mandatory phase 

becomes effective. The trigger level for the mandatory phase is 100 p.g/m3 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.

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 PM10 concentration of 196 p,g/m3 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 reduction. 

Over control is defined as the difference between the 24-hour National Ambient 

Air Quality Standard for PM10 (150 p,g/m3

) and the maximum modeled PM10 

concentration value with control measures in place (133 p,g/m3), which equals 17 

p,g/m3 • This 17 p,g/m3 is equal to approximately 27% which meets the 

contingency requirements established by the Clean Air Act. See the calculations 

below.

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 of the 

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 PM10 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 D EQ 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 PM10 from the sources in the Pinehurst area. 

With controls in place to remove and reduce sources of PM10, primarily 

from uncertified woodstoves, the PM10 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 

PM10 (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 PM10 emissions and ambient PM10 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 of particulates on human 

health are directly related to their chemical 

composition and size. Small particles, 

referred to as PM10 (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. 

PM10 can cause breathing problems, lung 

tissue damage, even cancer, and aggravate 

existing lung and heart diseases. People 

most sensitive to the effects of PM10 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 PM10 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. PM10 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? 

PM10, 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 PM10: 

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.
