1.0	Purpose

Annual Review Requirements:

According to 40 CFR part 58.26, an annual State fine particulate (PM2.5)
air monitoring report must be submitted to the regional administrator by
July 1, 2006, which describes the “proposed changes to the PM
Monitoring Network Description" and must be in accordance with the
annual network review requirements in § 58.25.  Recent additions to
federal grant performance guidelines, according to 40 CFR Part 31.40,
stipulate that recipients are required to submit performance reports
summarizing accomplishments, reasons for “slippage” if expected
outcomes are not met, and any cost over runs, if appropriate.  This
report is intended to fulfill these requirements.

An additional goal of the network review is to summarize the design of
the particulate network currently in operation, identify deficiencies
and redundancies and to propose modifications.  More details about
requirements of the contents of the annual report are found in previous
reports, but are omitted here for brevity.  Also, in-depth discussions
about the network design are contained in the PM Monitoring Network
Description and the annual reviews from previous years.  These documents
provide the necessary background for the particulate monitoring
networks.

On January 17, 2006, the EPA proposed changes to the Ambient Air
Monitoring Network design and the particulate matter National Ambient
Air Quality Standard (NAAQS).,  The proposed changes to the monitoring
network include more use of continuous technologies if the continuous
monitors can reach an Approved Regional Method (ARM) status or become
designated as a Federally Equivalent Method (FEM).  Another proposed
change is the reduction of the number of sites using Federal Reference
Method (FRM) and/or speciation samplers.  The design of the resulting
PM2.5 network may be quite sparse when compared to the current network,
especially in heavily populated areas that have been designated as
nonattainment.  

The proposed changes to the NAAQS state that the 98th percentile of
24-hour readings cannot exceed 35 ug/m3 when averaged over three years. 
The annual form of the standard remains the same at 15.0 ug/m3.  The EPA
is also taking comments about a short-term visibility standard.  One
possible scenario for this visibility component is to use a 4-hour
average calculated from noon to 4:00 p.m.  The form of the standard
could be any where from the 92nd to 98th percentile.  The level of the
visibility component of the PM standard may be from 20 ug/m3 to 30
ug/m3. 

The 2006 PM2.5 Annual Report uses historical data to evaluate the impact
of these scenarios on the status of attaining the NAAQS.  Samplers in
jeopardy of not meeting the proposed NAAQS need to be retained. 

2.0	Proposed Changes to the Monitoring Regulations and PM2.5

NAAQS that Impact on PM2.5 FRM, Continuous and Speciation 

	Network Design

Impact from Possible Changes to the Monitoring Regulations

The following discussion summarizes the PM network design elements in
the January 17, 2006 proposal.  Siting criteria still focus on
population-oriented sites that are neighborhood-scale and larger.  Data
generated from population-oriented middle-scale sites can still be
compared to both the 24-hour and annual forms of the NAAQS, if the site
can represent other middle-scale sites.  However, if the middle-scale
site is unique, the data it generates can only be compared to the
24-hour form of the NAAQS.  Background and transport sites are still
required in the network design.  IMPROVE stations can be substituted for
background locations. 

The proposed regulations also change the number of monitors that are
required by population levels and spatial coverage of a population unit.
 These are summarized in Table 1 as originally published in Table D-4 of
the Revisions to the Ambient Monitoring Regulations.  Even though the
NAAQS may be more stringent and more areas may face nonattainment, if
metropolitan statistical areas are combined into combined statistical
areas, fewer monitoring sites are required by the design in Table 1. 
The reduction in monitoring sites is especially evident in areas with
particulate levels above the NAAQS.

(CSA) as a whole, where applicable.

4 Metropolitan Statistical Areas (MSA) must contain an urbanized area of
50,000 or more population.

5 Population based on latest available census figures. 

The EPA has said that the goal is to reduce the number of FRM monitors
by 40 percent.  If the network design elements in Table 1 are applied,
the network described in Table 2 results.  These changes illustrated in
Figure 1.  The density of monitoring sites in the Detroit area may be
reduced from 13 to 2 and is clearly inadequate to support various
multifaceted data needs.

If a network design based on individual MSAs is used instead of the CSA
approach, coverage is increased in other areas of the state.  The
Detroit nonattainment area still has insufficient numbers of monitors to
collect the data necessary to develop attainment strategies and
implementation plans, as shown in Table 3 and Figure 2.  Data from all
monitors in Southeast Michigan has been used to understand the nature of
PM2.5 and its spatial variability.  Developing a workable SIP is
especially difficult because of inexperience working with PM2.5, lack of
adequate models, chemical variability of PM2.5 and a possibly more
stringent NAAQS.  Ambient data is a critical tool for development of the
SIP. 

The proposed monitoring regulations state that the co-location
requirement for the FRM samplers will remain at 15 percent.  The
sampling frequency for co-location may be changed from once every six to
once every 12 days, but contradictory statements are made in the January
17, 2006 CFR.  The proposed monitoring regulations also state that half
of all PM2.5 sites will be required to contain a continuous sampler,
even if the continuous sampler cannot achieve status as an FEM or as an
ARM.  Thirty percent of the ARMs must be co-located with a FRM sampler
that operates on a minimum sampling frequency of once every six days.

Sites that are more “influential” in determining the attainment
status of the 24-hour NAAQS may need continuous and/or speciation
samplers moved to these locations. 

PM10-2.5 will not be addressed in this annual report.  After the
PM10-2.5 network design is finalized and network deployment begins,
PM10-2.5 will be added to in the annual PM report.  At this point,
funding is too uncertain to begin to undertake the design of the
network.

We need to remain cognizant of the proposed changes to the monitoring
regulations when performing the annual network review to insure that the
resulting network continues to meet all regulations.

Impact from the Proposed PM NAAQS

The impact of the new PM2.5 NAAQS must be considered before any changes
are made in the design of network or, ideally, before any reduction in
federal funding occurs.  The proposed NAAQS includes modifications to
the level of the annual standard, possible adjustments to the form of
the 24-hour standard and a wide range of changes to the level of the
24-hour standard.  A secondary standard, based on a short-term average
ranging from 4 to 8 hours, as well as PM10-2.5 (coarse) standard are
also proposed. 

Historical data from all of the monitors in Michigan was compared to the
levels of the NAAQS proposed in January.  Figure 3 shows the possible
future attainment status in Michigan using the proposed annual and
24-Hour forms of the NAAQS.  The Grand Rapids area and Detroit
metropolitan area will have difficulty meeting the new 24-hour form of
the standard. 

From the preceding analysis, it is evident that certain FRM monitors
will need to be retained to meet the proposed monitoring regulations:
Lansing (260650012), Bay City (260170014), Coloma (260210014) and
Kalamazoo (260770008).  In addition, Houghton Lake (261130001) needs to
remain functional as a background site.  This will be especially
critical if the Seney IMPROVE site is lost.  Since Dearborn (261630033)
is the controlling site in the Detroit nonattainment area, it will need
to be retained.  The Allen Park Site (261630001) is the trend site for
Michigan and therefore will need to be retained.   

The extent of possible nonattainment areas will be heavily impacted by
network design as well as the level and form of the NAAQS.  At this
time, it is premature to remove any PM2.5 FRM samplers.  The individual
monitors in Kent, Ottawa, Allegan, Muskegon, Saint Clair, Genesee,
Oakland, Macomb, Monroe and Washtenaw will need to be retained to
eventually prove attainment of those counties (providing that an
attaining county may be split out of a CSA) to accurately assess the
extent of the possible nonattainment area in Grand Rapids and  to
accurately determine the extent of nonattainment in the Detroit area. 
As discussed above, the high density of monitors in Wayne County, as
well as other Detroit area locations, are critical in the development of
an attainment strategy.

Another component of the PM2.5 NAAQS is the introduction of a possible
short-term visibility standard.  If enacted, depending upon the level
and form of the standard, many locations in Michigan could face
nonattainment as shown in Figure 4.  Therefore, given the risk of
possible nonattainment across Michigan, it is premature to discontinue
any continuous monitoring stations until the status of the visibility
component of the PM NAAQS becomes clear. 

Since the status of the monitoring regulations and NAAQS legislation is
pending, the MDEQ is unable to suggest definite changes to the network
at this time.  This year’s annual report will focus on the merits of
each monitor, and outline plans for their continuation.  As usual, the
MDEQ will summarize data collected during the previous year and identify
modifications to the network.  A discussion of the PM10 network or
proposed PM10-2.5 network are beyond the scope of this report, but will
be considered in the annual network review, scheduled for summer/fall
2006.

3.0	Monitoring Objectives

The objectives of the PM2.5 monitoring program in Michigan are to:

	(	Elucidate levels of fine particulate material at population-oriented
sites in major population centers in Michigan;

	(	Provide real time reports on concentrations of fine particulates in
major metropolitan areas; 

	(	Generate data to determine long-term trends;

	(	Measure PM2.5 levels being transported into Michigan;

	(	Determine transnational transport;

	(	Assess background levels of fine particulate material;

	(	Collect data to assess compliance with 24-hour and annual National
Ambient Air Quality Standards (NAAQS);

	(	Investigate spatial and temporal variations; assess homogeneity;

	(	Determine source culpability in areas expected to have the highest
levels of fine particulates; and

	(	Determine the chemical composition of fine particulate material.

4.0	Network Design & Deployment Status

Michigan’s particulate network is multi-faceted to help provide a more
complete picture of the nature of particulate material within the state.
 PM2.5 concentrations are measured over a 24-hour time period using the
federal reference method (FRM).  Short-term PM2.5 or PM10 are determined
on an hourly basis at sites in the continuous network.  Chemical
composition of fine particles is determined by the speciation network
and by chemical analysis of a limited number of filters from the FRM
network.  

In addition to these networks, specialized measurements of fine
particulate are made in Michigan.  Continuous measurements of carbon
black have been added to Michigan’s network at four locations by using
aethalometers manufactured by MacGee Scientific.  A continuous elemental
carbon/organic carbon (EC/OC) monitor from Sunset Labs was recently
added to the Detroit/Newberry School (261630038) site, as was speciated
organic carbon measurements. 

PM2.5 FRM Network Design:

Rupprecht and Pattashnick (R&P) sequential PM2.5 samplers have been
deployed at the 25 sites that make up Michigan’s PM2.5 FRM network,
shown in Figure 5.  Additional information about network operations and
monitoring objectives are provided in Table 4.  Changes to the network
are discussed in part 5.0.

	Continuous Network Design and Deployment Status:

In 2006, the MDEQ continues to operate a continuous fine particulate
network of thirteen sites, shown in Figure 6.  Other than the LADCO site
at Seney, and the two new special purpose sites in Detroit, all the
PM2.5 continuous monitors in Michigan are R&P Tapered Element
Oscillating Microbalance (TEOM) instruments equipped with a filter
dynamic measuring system (FDMS) to make the data as FRM-like as
possible.

The new station at the Michigan Family Independence Agency (FIA) at 2000
West. Lafayette Street became operational in August 2005.  An older
model TEOM was added to the site to allow comparisons with Newberry
School (261630038).  A second TEOM that is equipped with a FDMS was also
added to FIA to permit comparisons with the rest of the continuous
network. 

However, due to persistent monitor malfunctions during periods with
elevated dew points, the MDEQ will be operating TEOMs without the FDMS
inlets during the ozone seasons (April 1 – September 30) at all sites
except FIA where a FDMS-equipped TEOM is operating for comparison
purposes. 

Table 5 summarizes the start-up dates for the TEOMs and the dates that
the FDMSs were added to the monitors.  LADCO has opted not to add an
FDMS to their TEOM at Seney.

Speciation Network Design:

The primary monitoring objectives of Michigan’s speciation network are
to provide data that will be used to support the development of
attainment strategies and to determine robust air quality exposure data
in population-oriented areas.  Single event Met-One spiral ambient
speciation samplers (SASS) are used throughout Michigan’s network. 
Most of the sites shown in Figure 7 are population-oriented stations. 
Table 6 shows the start-up dates for the speciation network in Michigan.

A subset of these speciation stations are located in areas recently
designated by the EPA as nonattainment for fine particulate.  The
speciation data collected by the monitors at Allen Park (261630001),
Dearborn (261630033) and Luna Pier (261150005) sites in the Detroit MSA
may be used in the development of attainment strategies for these areas.
 The data from Luna Pier is being used to characterize PM2.5 arising
from transport.  Data from the nearby Ypsilanti (261610008) monitor may
also help in SIP development by supplying urban upwind data.

The Ypsilanti speciation site (261610008) also provides air quality data
for Washtenaw County Health Department and other researchers in their
investigation of elevated asthma levels in that area. 

Although Grand Rapids is currently attaining the NAAQS, it isn’t
likely to meet a more stringent form of the standard.  The speciated
PM2.5 data collected at this site (260810020) will be valuable for
future SIP planning purposes and in comparing the differences in
chemical composition across large metropolitan areas.  Grand Rapids is
the second largest population center in Michigan, with the MSA exceeding
1 million people.  In various documents discussing the NCORE plans,
Michigan would be allocated two NCORE level 2 sites.  Grand Rapids will
likely be the second NCORE site. 

The Holland (260050003) speciation site characterized the composition of
material that is transported from Chicago, providing valuable
comparisons between the west and east side of the state.  Speciation
monitoring was discontinued April 2006 due to insufficient funds.

The Kalamazoo (260770008) site has the highest PM levels outside of the
Detroit area.  This area will likely be designated as nonattainment
under more stringent form of the NAAQS.  Speciation data will be
invaluable in developing an attainment strategy for this location.  

Due to the population-oriented nature of the site, Allen Park
(261630001) is the trend site for the Detroit MSA.  It has been
operational since January 1, 2001, and samples on a once every three day
schedule with a single event Met-One SASS.  This site will provide
valuable data for attainment strategies, trend data and data to identify
spatial patterns.

A speciation monitor is operational at Houghton Lake (261130001) to
provide background information for regional modeling.  To address
transport from the west and from the south, and to assess more rural
concentrations of speciated PM2.5, an additional site is located at Luna
Pier (261150005). 

An IMPROVE site at Seney Wildlife Refuge (261530001) is collecting
information to support visibility modeling efforts.  It is in jeopardy
of being discontinued due to cuts in the IMPROVE budget.

5.0	PM2.5 FRM Network Proposed Changes

Co-location Changes:

None are proposed. 

Sampling Frequency Changes:

In April 2006, sampling frequency changes were implemented at selected
sites in response to a federal budget cut as shown in Table 7.  The
possible impact of these changes on future attainment status is assessed
by altering the sampling frequency of historical data and analyzing the
impact.

Table 7: Changes in FRM Sampling Frequency of Primary Monitors

An analysis of the impact of sampling frequency changes on attainment
status was performed using historical data and modifying the sampling
frequency to reflect the changes shown in Table 7.  The results are
shown in Figures 8 to 9.  In this example, reducing the sampling
frequency  results in reduction of both the annual average and 98th
percentile values.  Even though the number of samples collected at the
effected sites is markedly reduced, requiring the use of the maximum
24-hour value as the 98th percentile value, the dates with higher PM2.5
levels were missed by using the once every six day sampling schedule. 
The effect becomes even more dramatic if the once every three day
schedule used at all sites is compared with the once every six day
schedule used at all sites except Allen Park.  A reduction in sampling
frequency tends to under estimate the risk to Michigan’s population. 
For this reason, the MDEQ requests funding to restore the sampling
frequency to a minimum of once every three days for all primary
monitors. 

This analysis also shows that the sampling frequency of the PM2.5 FRM
sampler in Kent County is a critical factor in determining attainment
status.  This site shows much “flip flopping” in and out of
attainment as a function of changes in the sampling.  It is essential
that the Grand Rapids site be restored to daily sampling to prevent the
occurrence of this attainment pattern.

Monitor Site Changes: 

The Saginaw site was closed in December 30, 2005 due to loss of site
access.  Saginaw Valley State University (SVSU) has been expanding
regularly since the station was established and student housing had
encroached upon the station.  The TEOM at Saginaw was shut down on
December 1, 2005.  Prior to shut-down of the Saginaw site, another TEOM
began operation at Bay City on November 19, 2005 to ensure that a
continuous stream of overlapping data was collected.

The Ann Arbor (261610005) PM2.5 FRM sampler was located on a roof top on
Hayward Drive on University of Michigan (U of M) campus.  Trees began
encroaching upon the rooftop, so the site was closed.  Access was also
problematic.  However, another FRM sampler is still operational in
Washtenaw County at the Ypsilanti (261610008) site. 

A new tribal site was established in Manistee (261010922) by the Little
River Band of Ottawa Indians.  It began operation on April 2, 2006.

A special purpose monitoring project was conducted in Michigan’s Upper
Peninsula to investigate the impacts from smoke from Outdoor Wood
Boilers (OWB) on fine particulate levels.  Monitoring began in October
2005 and continued through April 2006.  A background site was
established in Crystal Falls (260710001) in Iron County.  A site
impacted by OWBs was established in Channing (260430002) in Dickinson
County.

PM2.5 Continuous Network Proposed Changes

Monitor Site Changes: 

Since the last PM2.5 Annual Air Quality Report was written, two TEOMs --
one equipped with an FDMS and the other an inlet adapter -- became
operational at FIA/Lafayette (261630039) on August 20, 2005. 

The continuous site at Saginaw (261450018) was discontinued on December
1, 2005 due to site access problems.  To maintain coverage necessary for
AIRNOW and PM2.5 forecasting, a TEOM was added to the Bay City
(260170014) on November 19, 2005 to replace the Saginaw site. 

As a result of budget cuts, the TEOM/FDMS B unit at Holland was shut
down on April 1, 2006. 

It appears that the Seney TEOM will be closed at the end of the ozone
season due to loss of funding by the Midwest RPO.

TEOM Operational Changes: 

In an attempt to make the continuous data more FRM-like and avoid
humidity problems associated with the FDMS inlets, all FDMs inlets were
removed from the TEOMs before April 1, 2006.  They will be replaced
after September 30, 2006.  The exact dates the FDMS inlets were removed
in shown in Table 8.  Since FIA has TEOMs equipped both ways, no changes
were made to configurations at that site.

The proposed changes to the monitoring regulations suggest that if
continuous data is deemed “FRM-like” it may be used to determine
attainment status and, as a result, some of the manual FRM samplers may
be shut down.  Region 5 EPA, in conjunction with state and local
agencies in the region as well as LADCO, has analyzed continuous data
generated in the region to determine if it qualifies as an Approved
Regional Method (ARM).  According to specifications outlined in the CFR,
data points falling within the trapezoid are deemed FRM-like.  Figure 10
shows how Michigan’s data fares.  Like other states in Region 5, most
of Michigan’s data can’t meet the FRM-like status. 

 

Figure 10: Evaluation of MDEQ’s Continuous Data to Determine
Eligibility

as an Approved Regional Method.

Only one TEOM meets the performance characteristics to satisfy the ARM
require-ments.  The Lansing TEOM is an old style monitor with the older
flow controllers.  Michigan has two of the newer model B FDMS inlet
adapters.  One was installed at the Saginaw monitor and the other at
Holland.  Note the variability in performance of the TEOM/FDMS B units. 
Holland meets the specifications to qualify as an ARM, but Saginaw does
not.  

Figure 11 shows how the seasonal performance of the TEOM/FDMS in
relation to the ARM specifications.  This casts doubt on the accuracy of
the method over different seasons in the Midwest.

Method.

PM2.5 Speciation Network Proposed Changes

Sampling Frequency Changes:

No changes to the sampling frequencies of speciation samplers are
anticipated at this time.  Because the laboratory costs associated with
operating the speciation network have risen rapidly over the previous
few years, it appears likely that if additional cuts are made to the
PM2.5 budget, a reduction in the speciation sampling frequency may be
necessary to help preserve the spatial coverage of the network while
still collecting some of the speciation data necessary for planning
purposes. 

Monitor Site Changes:

As a result of budget cuts, the SASS speciation sampler at Holland was
shut down on April 1, 2006. 

The site at Seney (261530001) is in jeopardy of being discontinued due
to cuts in the IMPROVE budget.   Data redundancy will be one of the
factors used to determine which IMPROVE sites will be selected for
closure.  Fortunately, the data generated by the Seney site is unique,
so it may be spared. 

Fine Particulate Data Summary

The following section summarizes the degree of data capture and the
observed PM2.5 values for each monitor since its start-up date.  For
2006, only January through March data are available.  Beginning in
April, sampling frequencies were changed as a result of the cut to the
PM2.5 budget. 

Data Completeness:

Table 9 illustrates the data capture by monitoring site. The
calculations in the table are limited to each individual monitor; no
data substitution has been performed to correct for missing data.  The
table also shows the changes to the sampling frequencies that occurred
beginning in the second quarter. 

The co-located precision monitor at Kalamazoo didn’t achieve 75
percent data capture during the forth quarter 2005.  Saginaw collected
74% complete data during the second quarter 2005.

Repeated vandalism beginning on September 5, 2005 caused Newberry to be
temporarily shut down on September 10, 2005.  Security measures were
enhanced and the station was reopened on April 2, 2006.  A portion (73
percent) of the scheduled samples were collected during the third
quarter 2005.  No data was captured during the fourth quarter 2005 and
first quarter 2006. 

All data was validated and uploaded to AIRS within 90 days after the end
of each quarter. 

Annual Averages:

Table 9 also shows the annual averages for each monitoring site.  Annual
averages for sites that have been closed are also included in the table.
 

The highest annual average of 18.55 ug/m3 was measured at Dearborn
(261630033) during 2005, which is an increase from the 2004 average of
16.8 ug/m3.  The three-year running average at Dearborn equals 18.2
ug/m3.  Nearby sites had three-year annual averages equaling 16.4, 15.1
and 15.5 ug/m3 for SWHS (261630015), Allen Park (261630001) and
Wyandotte (261630036), respectively.  Too few measurements have been
collected so far at Newberry School (261630038) for a valid comparison,
but the levels appear to be about 2.1 ug/m3 less than those at Dearborn.

The possible downward trend that began in 2004 was fleeting due to the
unusual meteorological conditions that were common in 2004. 

24-Hour Values:

Three-year annual averages of the 98th percentile values are shown in
Table 10.  The 98th percentile values that are greater than the proposed
level of 35.0 ug/m3 are shown in bold.  The highest 24-hour values were
measured at Dearborn (261630033), usually reaching into the low to mid
40 ug/m3 range.  During the first quarter of 2006, the 98th percentile
at Dearborn reached 43.4 ug/m3.

9.0	Quality Assurance/Quality Control

In accordance to 40 CFR Part 58, independent audits are conducted
quarterly by the MDEQ quality assurance staff on each PM2.5  FRM and
SASS monitor.  Each TEOM is audited at least once a year.  The results
of these audits are available by request through the Air Monitoring
Unit’s Quality Assurance Coordinator. 

Specific protocols regarding quality assurance, laboratory analysis
sample handling, collection, transport, laboratory sample identification
and archive procedures are covered in the Quality Assurance Project Plan
for the PM2.5 Program in Michigan.

Co-located Sites:

Fifteen percent of the monitoring sites in Michigan contain a co-located
R&P sequential FRM monitor, meeting the national precision requirement. 
The locations are listed in Table 11.

Precision:

Table 12 shows the coefficient of variation for co-located pairs of FRM
monitors from 1999 through 2005 for those data points with a
concentration greater than 6.0 ug/m3.  For the same time span, the
coefficient of variation is also calculated using a cut-off value of 3.0
ug/m3 to compare the impact the proposed changes to the monitoring
regulations would have on precision, and to provide a historical record
using the proposed criteria.  As shown by the historical data, it
appears that the co-located monitors will easily be able to meet the new
precision requirements.

Performance Evaluation Audit (PEP) Results:

Performance audits are conducted by the EPA to independently verify the
accuracy of data reported by an agency.  For the PM2.5 FRM network, an
EPA contractor deploys a URG audit sampler at preselected stations that
vary every year.  The contractor operates the sampler, independently
from the activities of MDEQ staff, but on the same dates.  The filters
are analyzed by a laboratory other than the MDEQ lab to identify bias
throughout the system.  Table 13 shows the results from the performance
evaluation audits from 1999 to 2005.  POC 1 refers to the primary
sampler operating on either a daily or on a once every three day
schedule.  POC 2 refers to the precision sampler that operates on a once
every six day schedule.

Table 12 summarizes the differences between co-located samplers. 
Because the number of sample pairs is relatively high, the coefficient
of variation is relatively insensitive to a couple of outlying data
points, generating much better comparative data than that shown in Table
13.  The limited number of PEP sample pairs precludes calculation of the
coefficient of variation, and each event must be considered on its own
merit. 

Some of the performance audits show widely divergent results, such as
the January 19, 2005; May 31, 2005; and November 15, 2005 audits at
Saginaw and Bay City.  The levels of PM2.5 at stations in the northern
central region of Michigan track each other very well and are lower than
the results reported on these days by the PEP sampler.

However, the PEP audit conducted at Linwood on April 7, 2005 more
closely reflects PM2.5 levels of other stations in the Detroit area. 
The Linwood value seems to be elevated, but a cause couldn’t be
identified to justify invalidation of that sample.  

10.0	Summary & Conclusions

FRM network design changes that would be mandated by the proposed
monitoring regulations result in a network that is too sparse in large,
densely populated areas not meeting the NAAQS.  Changing the design
metric from using a combined metropolitan area approach to individual
metropolitan statistical areas doesn’t improve.  Monitor placement is
inadequate to support SIP and modeling activities.  Data analysis needs
such as weight of evidence and trends analysis could also be compromised
if these site reductions occur.  

The level and form of the PM NAAQS may have a profound impact on
attainment status in Michigan.  Since it is impossible to prove
attainment without data, no sites in possible nonattainment areas should
be eliminated at this time.

Reducing the sampling frequency of FRMs may create instability in the
value of the 98th percentile causing sites to flip in and out of
attainment.  Sites that may be susceptible to this behavior should
retain a more frequent sampling schedule.  One purpose behind the 1997
modifications to the NAAQS was to promote better stability of the
metrics used to judge attainment.  Funding that is adequate to support
greater sampling frequencies of the FRMs need to be restored as soon as
possible.

Continuous PM2.5 measurements are an important tool for determining
compliance with any visibility component of the NAAQS, AIRNOW reporting
and forecasting levels of fine particulate.  

Due to the uncertainties in the changes to the proposed monitoring
regulations, the level and form of the changes to the PM NAAQS and
funding levels, it is difficult to plan changes to the particulate
network.  The likelihood of nonattainment in western Michigan
necessitates retaining as many FRM sites as possible.  If these areas do
indeed have difficulty meeting a more stringent standard, chemical
speciation data is vital to understanding the nature of the particulate
problem and developing effective controls.  Also, to safe guard the
population of Michigan, it is vital that a once every three day sampling
frequency be retained.  Although it is doubtful that Michigan can
generate continuous data that is more FRM like, forecasting and AIRNOW
mapping require access to continuous data.  Given all these conflicting
objectives and  reductions in funding, prioritizing components of the
particulate program will be a challenge.  Criteria will need to be
developed to evaluate and prioritize various goals in the program.  The
MDEQ will work with Region 5 EPA in this arduous task.
