jority of documents are multidisciplinary in nature, the Primary Field/Group assignment(s) will be specific discipline, area of human
endeavor, or type of physical object. The application(s) will be cross-referenced with secondary Field/Group assignments that will follow
the primary posting(s).
18. DISTRIBUTION STATEMENT
Denote releasability to the public or limitation for reasons other than security for example "Release Unlimited." Cite any availability to
the public, with address and price. /
19. & 20. SECURITY CLASSIFICATION
DO NOT submit classified reports to the National Technical Information service.

-------
Background
The operation of the National Air Surveillance Network
(NASN) was decentralized in fiscal year 1974. Responsibility
was passed from the National Environmental Research Center
in Research Triangle Park, North Carolina, to Region VI and
operation began January 1974 at the Surveillance and Analysis
Division's Houston Branch. In July 1975 the network was
further decentralized when the states of Arkansas, Louisiana,
New Mexico, and Oklahoma accepted responsibility for the
operation and maintenance of the NASN stations located in
their respective states. The State of Texas accepted respon-
sibility in January of 1976.
Summary of Activities
The routine preparation and mailing of reagents, filters,
supplies, and equipment was continued through July 1975 for
all states except Texas, which was supplied through December
1975. Since the July assumption of NASN duties by four of the
states in Region VI, an analytical quality control program
involving split samples for nitrogen dioxide and sulfur
dioxide has been in effect. Similarly, the integrity of the
particulate data is assured through calibration of high -
volume sampler orifices at the Houston Branch.

-------
The lower limit of detection for SO2 using the
Technicon II procedure is estimated to be approx-
imately 4 ug SO per milliliter, which represents a
concentration of approximately 4 ug S02 per cubic
meter for ambient air. When using the manual method
for SO ,. the lower detection limit is approximately
2
25 ug S02 per cubic meter . For N0«» the detection
limit is given as 0.02 ug N02 per milliliter,
corresponding to an ambient concentration of about 5 ug
NO per cubic meter. Therefore BD will designate
N02 or SO concentrations below the appropriate
detection limit.
