RE:
California State Board of Equalization
Closure Report Addenda
In February 2012, LaCroix Davis LLC (LCD) and the Department of General Services Mold
Remediation Project Team completed the mold remediation activities initially scheduled for the
State Board of Equalization (BOE) building located at 450 N Street, Sacramento, California. At
the completion of mold activities on each floor (except Floors 22 through 24), a closure report for
the completed floor was issued by LCD to summarize key events of the project. Subsequent to
the completion and release of these closure reports, information not previously available and
information documenting additional mold-related activities was compiled by LCD. A Closure
Report Addendum of this information has been prepared for each floor and is submitted to you by
means of this submittal.
This submittal package includes the following:
 Four (4) hardcopy sets of individual Closure Report Addenda for Floors 1 through 21.
 Each hardcopy set includes a DVD with electronic files of the complete contents presented in
the Closure Report Addenda.
 Four (4) binders containing Additional Information for activities in which LCD was involved
on Floors 22 through 24; LCD was not involved in the initial remediation of mold on these
three floors and the original Closure Reports for these floors were issued by BioMax.
Each recipient of a hardcopy set and binder will be instructed to insert each Closure Report
Addendum into the rear of its respective Closure Report. LCD has included a “tab” so that this
section of the report can be easily accessed in the future. It is intended that as new information is
generated for a specific floor, the new information will be added to this section of the Closure
Report.
Very truly yours,
LaCroix Davis LLC

Comments:A) 5 of the raw count Cladosporium spores were present as a single clump. 7 of the raw count Penicillium/
Aspergillus type spores were present as a single clump.
* Most of these spore types are not seen with culturable methods (Andersen sampling), although some may appear as non-sporulating fungi.
Most of the basidiospores are "mushroom" spores while the rusts and smuts are plant pathogens.
† The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing
characteristics. They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and
may be undercounted.
††Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility
for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and
may be higher then reported. It is important to account for samples volumes when evaluating dust levels.
The Limit of Detection is the product of a raw count of 1 and 100 divided by the percent read. The analytical sensitivity (counts/m3) is the
product of the Limit of Detection and 1000 divided by the sample volume.
‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is
reflected by the value of "x".
§ Total Spores/m3 has been rounded to two significant figures to reflect analytical precision.

† The Typical Outdoor Data by Date represents the typical outdoor spore levels across North America for the month indicated. The last column
represents the frequency of occurrence. The low, medium, and high values represent the 2.5, 50, and 97.5 percentile values of the spore type
when it is detected. For example, if the frequency of occurrence is 63% and the low value is 53, it would mean that the given spore type is
detected 63% of the time and, when detected, 2.5% of the time it is present in levels above the detection limit and below 53 spores/m3. These
values are updated periodically, and if enough data is not available to make a statistically meaningful assessment, it is indicated with a dash.
‡ The Typical Outdoor Data by Location represents the typical outdoor spore levels for the region indicated for the entire year. As with the
Typical Outdoor Data by Date, the four columns represent the frequency of occurrence and the typical low, medium, and high concentration
values for the spore type indicated. These values are updated periodically, and if enough data is not available to make a statistically meaningful
assessment, it is indicated with a dash.
§ Total Spores/m3 has been rounded to two significant figures to reflect analytical precision.
*The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related
growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore
types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces
rapidly and are very easily dispersed. Other genera are usually present in lesser numbers.
**These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens.
However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of
a single morphological type of basidiospore on an inside sample should be considered significant.

Comments:A) 33 of the raw count Penicillium/Aspergillus type spores were present as a single clump. B) 10 of the raw count
Cladosporium spores were present as a single clump.
* Most of these spore types are not seen with culturable methods (Andersen sampling), although some may appear as non-sporulating fungi.
Most of the basidiospores are "mushroom" spores while the rusts and smuts are plant pathogens.
† The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing
characteristics. They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and
may be undercounted.
††Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility
for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and
may be higher then reported. It is important to account for samples volumes when evaluating dust levels.
The Limit of Detection is the product of a raw count of 1 and 100 divided by the percent read. The analytical sensitivity (counts/m3) is the
product of the Limit of Detection and 1000 divided by the sample volume.
‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is
reflected by the value of "x".
§ Total Spores/m3 has been rounded to two significant figures to reflect analytical precision.

† The Typical Outdoor Data by Date represents the typical outdoor spore levels across North America for the month indicated. The last column
represents the frequency of occurrence. The low, medium, and high values represent the 2.5, 50, and 97.5 percentile values of the spore type
when it is detected. For example, if the frequency of occurrence is 63% and the low value is 53, it would mean that the given spore type is
detected 63% of the time and, when detected, 2.5% of the time it is present in levels above the detection limit and below 53 spores/m3. These
values are updated periodically, and if enough data is not available to make a statistically meaningful assessment, it is indicated with a dash.
‡ The Typical Outdoor Data by Location represents the typical outdoor spore levels for the region indicated for the entire year. As with the
Typical Outdoor Data by Date, the four columns represent the frequency of occurrence and the typical low, medium, and high concentration
values for the spore type indicated. These values are updated periodically, and if enough data is not available to make a statistically meaningful
assessment, it is indicated with a dash.
§ Total Spores/m3 has been rounded to two significant figures to reflect analytical precision.
*The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related
growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore
types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces
rapidly and are very easily dispersed. Other genera are usually present in lesser numbers.
**These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens.
However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of
a single morphological type of basidiospore on an inside sample should be considered significant.
