• Air Sampling and Monitoring Protocol
Site: 130 Cedar Street
Prepared for Masterworks Development
.45-micron mixed cellulose ester (MCE) membrane 25mm in diameter with a
conductive cowl on a cassette. Sample volumes will various due to various site-
specific conditions.
4) Silica Sampling: Silica samples will be collected according to NIOSH 7500
Method using XRD analysis.
5) Fibrous ekass Sampling: Fibrous Glass samples will be collected according to
.NIOSH 7+400 ethod using counting method "B".
6) Dioxin/Furan Wipe Sampling: D/F samples will be collected according to
ASTM method 6661-01 and analyzed by EPA Method SW-846-8290.
7) Poly Cyclic Aromatic Hydrocarbon Sampling: PAH samples will be collected
using ASTM method D6661-01 and analyzed using EPA method SW-846-8270C.
8) RCRA Metals Sampling: RCRA metals samples will be collected using wipe
samples pre-moistened with de-ionized water.
9) Mercury will be sampled Utilizing EPA modified method7471A.
10) Poly chlorinated bi Phenols will be sampled utilizing EPA modified method
8082.
4.0 Quality Assurance and Quality Control
Quality Assurance (QA) includes the systematic actions necessary to provide
adequate confidence that a measurement will satisfy a given requirement for
accuracy. Quality Control (QC) is the operation techniques that are used to fulfill
requirements for quality. The QC procedures for the air sampling and monitoring
sections of this protocol include planned equipment calibrations, preventative
maintenance of equipment, co-located sampling to evaluate precision and
analysis of QC samples consisting of field blanks and lab blanks.
5.0 ,,Alarm and Action Levels
Thegoal of the air sampling ' and monitoring protocol is to ensure the
Ilk deconstruction operations at the subject property do not have a negative impact
on the airborne environment of the surrounding community. Any action and
alarm levels that may be established and utilized for the COPC would be solely
for that. purpose rather than providing compliance with any known health
standard.
