Test Methods: Three New Methods for Velocity and Volumetric Flow
Rate Determination in Stacks or Ducts
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing three new optional test methods for measuring
velocity and volumetric flow rate of flue gas from fossil fuel-fired
boilers and turbines. These new methods can account for velocity drop-
off near the stack or duct wall and the yaw and pitch angles of flow.
Owners and operators of utility units subject to the Acid Rain Program
under title IV of the Clean Air Act and certain large electric
generating units and large non-electric generating units that may
become subject to the nitrogen oxides (NOX) state
implementation plan (SIP) call under Title I of the Clean Air Act must
use an approved test method to periodically calibrate the flow rate
monitors at these units. Flow rate data is used to determine the units'
sulfur dioxide (SO2) and NOX mass emissions and
heat inputs. The purpose of the Acid Rain Program and the
NOX SIP call is to significantly reduce emissions from
electric generating plants and other affected units in order to reduce
the adverse health and environmental effects of acid deposition or
ground level ozone resulting from these emissions.
DATES: Written comments must be received by June 14, 1999 unless a
hearing is held, in which case written comments must be received by
July 1, 1999.
Public Hearing: Anyone requesting a public hearing must submit a
written request, which must be received by EPA by no later than May 21,
1999. If a hearing is timely requested, it will be held on June 1,
1999, starting at 10:00 a.m.
ADDRESSES: Any written comments must be identified as comments on the
direct final rule and companion proposed rule, identified with Docket
No. A-99-14, and must be submitted in duplicate to: EPA Air Docket
(6102), Environmental Protection Agency, 401 M Street, SW, Washington,
DC 20460. The docket is available for public inspection and copying
between 8:30 a.m. and 3:30 p.m., Monday through Friday, at the address
given above. EPA may charge a reasonable fee for copying.
Public Hearing: If a hearing is held, it will take place at the 4th
floor conference room at 501 3rd Street, NW, Washington, DC 20001.
FOR FURTHER INFORMATION CONTACT: John Schakenbach, Acid Rain Division
(6204J), U.S. Environmental Protection Agency, 401 M Street, SW,
Washington, DC 20460, (202) 564-9158; or Elliot Lieberman, Acid Rain
Division (6204J), U.S. Environmental Protection Agency, 401 M Street,
SW, Washington, DC 20460, (202) 564-9136.
SUPPLEMENTARY INFORMATION: We are proposing to add three new optional
test methods for determination of velocity and volumetric flow rate in
stacks or ducts that account for yaw and pitch angles of stack or duct
gas flow and velocity drop-off near the stack or duct wall. We are
promulgating the new test methods as a direct final rule without prior
proposal because we view the rule as noncontroversial and anticipate no
adverse comment. We have explained our reasons for this action in the
preamble to the direct final rule. If we receive no timely adverse
comment, we will not take further action on this proposed rule. If we
receive timely adverse comment, we will withdraw the direct final rule
and it will not take effect.
We will address all public comments in a subsequent final rule
based on this proposed rule. We will not institute a second comment
period on this action. Any parties interested in commenting must do so
at this time. For further information, please see the information
provided in the direct final action that is located in the ``Rules and
Regulations'' section of this Federal Register publication.
Dated: May 5, 1999.
Carol M. Browner,
Administrator.
