Public Hearing to Consider Adoption of and Amendments to
Regulations Regarding Test Methods for Determining Emissions from
Nonvehicular Sources.

RECOMMENDATIONS

The staff recommends that the Air Resources Board (ARB or Board)
adopt four proposed ARB test methods developed by ARB staff. The
staff further recommends that the Board adopt proposed revisions
to four existing ARB test methods and adopt ten new proposed test
methods to reflect test methods promulgated by the Environmental
Protection Agency (EPA).

DISCUSSION

Determinations of gaseous and particulate matter emissions from
stationary sources ("source tests") are conducted, among other
reasons, to determine whether a source is complying with air
pollution control laws and regulations. The ARB is required, by
California Health and Safety Code Section 39607(d), to adopt
procedures ("test methods") by which source tests are conducted.
Since 1972, the ARB staff has developed and the Board has adopted
five test methods for the gasoline vapor recovery program and
sixteen test methods for a wide variety of other nonvehicular
emission types and sources. The ARB staff has continued to
develop new test methods and refinements to previously adopt test
methods.

The ARB staff is proposing for consideration four new test
methods, developed by the ARB staff, which respond to the need
for emission inventories and measurement of toxic air
contaminants. These test methods are Proposed ARB Method 401 for
volatile organic content of waste products, Proposed ARB Method
410A and 410B for benzene, and Proposed ARB Method 150 for
hydrocarbon emissions from fixed roof tanks. Proposed ARB Method
150 had been considered by the Board at the June 29, 1983 Board
meeting. Adoption of Proposed ARB Method 150 was postponed to
allow clarification of some technical points which were raised by
an industry representative at the meeting. These technical
points have been clarified.

The staff is also proposing for consideration ten new test
methods and proposing changes to four test methods previously
adopted by the Board. The wording of these proposed ARB test
methods and changes are based on test methods that are
promulgated by the EPA. The EPA has adopted these in response to
requirements of the National Emission Standards for Hazardous Air
Pollutants (NESHAPS) and New Source Performance Standards (NSPS)
programs.

Proposed ARB Methods 401, 410A, and 410B were subjects at
meetings of the CAPCOA Technical Subcommittee on Source Test
Methods for Toxic Air Contaminants on December 12, 1984 and April
25, 1985. Also, all of the proposed ARB test methods in this
report were subject to public comment at a workshop on source
test methods on August 25, 1985.

Adoption of standardized test methods promotes uniformity and
quality assurance in source testing activities. Through
uniformity and improved quality assurance, source testing
activities in California would help establish a uniform,
statewide, data base of air pollution information to which all
source testing participants would be contributing. The broadened
data base afforded by the standardized test methods would
increase the information input to such activities as emission
inventory, control method development, and modeling.

SUMMARY AND IMPACTS OF PROPOSED BOARD ACTION

Significant issues and public comments existing by the time of
the August 25, 1985 workshop have been addressed by subsequent
revisions in the test methods. The staff believes that there are
no significant adverse air quality, environmental, or economic
impacts if the Board acts on the staff's recommendation.
