CEMS Demonstration Announcement
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of request for proposals.
-----------------------------------------------------------------------
SUMMARY: The Office of Solid Waste, U.S. Environmental Protection
Agency, plans to conduct a demonstration of particulate matter (PM) and
total mercury (Hg) Continuous Emissions Monitoring Systems (CEMS) for
stack monitoring of hazardous waste combustors (e.g., incinerators,
cement kilns, and light-weight aggregate kilns that burn hazardous
waste). The purpose of this notice is to solicit proposals from vendors
that are interested in participating in the demonstration. EPA will
select vendors to participate in the demonstration based on specified
evaluation criteria.
DATES: Proposals must be submitted by May 7, 1996.
ADDRESSES: Vendors must submit an original and two copies of their
proposal to H. Scott Rauenzahn, U.S. Environmental Protection Agency,
401 M Street, SW (5302W), Washington, DC 20460.
FOR FURTHER INFORMATION CONTACT: For information on this request for
proposals, contact H. Scott Rauenzahn in the Office of Solid Waste at
703-308-8477 (FAX: 703-308-8433).
SUPPLEMENTARY INFORMATION: EPA plans to conduct a demonstration to
determine whether PM and total Hg CEMS are sufficiently developed for
use to document compliance with emission standards for hazardous waste
combustors. The demonstration has two phases: (1) demonstration of
ability to comply with the Agency's draft performance specifications;
and (2) demonstration of long term endurance over a period of six
months to one year.
I. CEMS Performance Specifications
The Agency's draft performance specifications contain requirements
for: a one-week test period for calibration and zero drift; relative
accuracy assessment against EPA manual reference methods; a calibration
error check (if applicable); an interference test (if applicable); and
demonstration to the EPA that other requirements, such as response time
and data recorder scale, are met. The draft specifications are
available on EPA's Technology Transfer Network (TTN). The files are
PM--PS.ZIP for PM and HG--PS.ZIP for Hg. They can be found in the
Emission Measurement Technical Information (EMTIC) bulletin board's
``Continuous Emissions Monitoring'' area.
The dial-in number for the TTN BBS is (919) 541-5742. That number
can accommodate 14.4k kbps. Settings are 8 (Data), No parity, 1 (Stop),
and Full duplex. The BBS can be reached on the internet via TELNET at
``ttnbbs.rtpnc.epa.gov''. The system is off-line Mondays from 8 am
until 12 noon ET. For help using the BBS, dial (919) 541-5384.
In addition, the draft performance specifications are available in
the EPA RCRA Docket, Docket number F-96-RCSP-FFFFF. The docket is
located at U.S. Environmental Protection Agency, Crystal Gateway, First
Floor, 1235 Jefferson Davis Highway, Arlington, Virginia. The RCRA
Docket is open from 9 a.m. to 4 p.m. Monday through Friday, except for
Federal holidays. The public must make an appointment to review docket
materials by calling 703-603-9230. The public may copy a maximum of 100
pages from any document at no cost. Additional copies cost $0.15 per
page.
II. Description of the Demonstration
EPA seeks vendors to participate in the demonstration that will
supply, install, and operate the CEMS at no charge to the government.
The Agency will select participants based on their proposals according
to the selection criteria discussed below. The test site(s) will be
selected by EPA. EPA will also provide site coordination and oversight,
and will conduct the manual method reference measurements.
The vendors will conduct the demonstration under EPA oversight, and
will provide to EPA at no charge and before removing the CEMS from the
test site all data and information on the design of the CEMS and its
operation and maintenance during the demonstration. EPA will present
the results of the demonstration in a report.
At least one CEMS of each type (PM and total Hg) that participates
in the demonstration will be selected for a long term (e.g., 6-12
month) endurance test.
The testing is scheduled to start in May 1996.
III. Vendor Proposals
Proposals should contain the following: a detailed description of
the design, operation, and maintenance of the CEMS; the performance
specifications of the device (including calibration and zero drift,
detection limits, range, and accuracy); a detailed description of the
calibration procedure(s) and standards; vendor generated test data
pertinent to CEMS performance and calibration; field data demonstrating
performance; a description of how the vendor will meet the
responsibilities of supplying, installing, and operating the CEMS; and
a statement that the vendor accepts the conditions of the program as
presented in this notice.
EPA will select vendors for participation in the demonstration
using the criteria presented below. Vendors selected after a
preliminary selection must submit a site-specific installation plan
based on site-specific information that the Agency will provide. This
plan should include details such as: (1) the strategy to be used for
handling the problem of liquid aerosol if the site uses
[[Page 7233]]
a low temperature, wet air pollution control system; or (2) how
adequate purge air and temperature would be maintained to prevent
fouling of the optics or optical access, if applicable. In other words,
the site-specific installation plan should describe all measures that
would be taken to ensure compliance with the performance specifications
if the site itself bought the CEMS.
EPA will review the site-specific installation plans and make a
final selection of participants.
IV. Selection Criteria
EPA will use the following selection criteria as guidelines for
choosing CEMSs to participate in the demonstration and endurance tests.
Each CEMS will be scored on a scale of 1 to 10 on each criterion (10
being the best score), and a total score calculated using the weighting
factors indicated in brackets. Starting from the highest scoring CEMS
and working down, as many CEMSs will be selected for participation as
possible commensurate with the resources available and the capacity of
the test site to accommodate additional CEMSs.
A prerequisite for consideration is that a CEMS must be able to
monitor PM or Hg continuously and record measurements over the
specified averaging periods. For this effort, EPA defines a CEMS as
sampling the stack gas continuously and making measurements every 15
seconds. One minute block averages are calculated by averaging the four
previous 15-second readings. Rolling averages are then calculated every
minute using all one-minute averages obtained during the averaging
period. The averaging periods are 10-minute, one-hour (60 minutes), and
2-hours (120 minutes) for PM, and 10 hours (600 minutes) for Hg. Only
CEMSs that have a data availability factor of at least 90% 1 will
be considered, unless no CEMSs can perform at that level.
\1\ Since a source would not be allowed to burn hazardous waste
if the CEMS is not measuring and recording data, the CEMS must have
a high data availability factor.
---------------------------------------------------------------------------
Phase I: Selection Criteria for the Demonstration Test
(1) Commercial Availability. The CEMS should be commercially
available as documented by product literature, a list of installation
locations, and references. A CEMS that has been installed and
successfully field demonstrated to meet performance specifications
similar to those referenced here at more than 100 stacks will receive
the highest score. One that is available as a prototype only, with no
firm commercialization plans in place that would lead to availability
within the year, will receive the lowest score. [25%]
(2) Vendor Support. The CEMS should be provided, installed, and
operated by the vendor at no charge to the government. It is expected
that the vendor will have personnel on-site to run the CEMS, carry out
CD and ZD checks if needed, perform the CE check (if applicable),
monitor CEMS performance during RA testing, and provide any trouble
shooting or maintenance that may be required. It is also expected that
all data will be recorded and copies provided to EPA at the test site
and at no charge: CD and ZD checks (if automatic adjustments are made
the CD or ZD before adjustment or the amount of adjustment must be
recorded), CE tests, RA tests, and interference checks. Willingness to
guarantee all of the above will receive the highest score, none of the
above the lowest score. [25%]
(3) Potential for CEMS to Meet Performance Specifications.
Documentation supplied by the vendor in the proposal should provide an
indication that the CEMS can be expected to: (1) meet the performance
specifications for CD, ZD, CE, RA, interferences, recorder scale, and
response time; and (2) meet detection limits of less than 7.0 mg/dscm
for PM and 5.0 g/dscm for Hg. Recorder scale (and span) should
be greater than or equal to 210 mg/dscm and 1400 g/dscm
respectively for PM and Hg. The response time, the time interval
between the start of a step change in the system input and the time
when the data recorder displays 95 percent of the final stable value,
should not exceed 2 minutes. Ability to meet all of the specifications
will receive the highest score, ability to meet none of the
specifications will receive the lowest score. [35%]
(4) Other Performance Requirements. The CEMS design (as evaluated
from information supplied in the proposal pertaining to a description
of the CEMS and measurement principle and/or supplied test data) should
be appropriate relative to the requirements of the performance
specification and the application to monitoring stack emissions from
hazardous waste combustors (i.e., hazardous waste incinerators and
hazardous waste burning cement and light-weight aggregate kilns). For
PM CEMSs, this means:
(a) The CEMS should be maximally sensitive to PM in the 0.1 to 10
size range; and
(b) The CEMS should not be sensitive to liquid water aerosol.
For Hg CEMS this means:
(a) The CEMS vendor must have demonstrated, at a minimum, the
ability of the CEMS to detect vapor phase Hg, Hg on PM, and HgCl
2, and report the sum of these concentrations as total Hg; and
(b) No interferences (see performance specification). [15%]
Modifications to Installation Plan. Vendors that the Agency selects
based on the criteria discussed above for participation in the
demonstration test must submit an installation plan. The proposed
installation described in the plan must be appropriate relative to the
requirements of the performance specification and the application to
monitoring stack emissions from the hazardous waste combustor that the
Agency specifies. In particular, factors such as flue gas conditions
(whether it is a saturated low temperature stream, for example) and
purge requirements (flow rate and temperature to ensure that optics and
access are not fouled) must be taken into account in the installation
plan. If EPA determines that the proposed installation plan is not
appropriate, the vendor may be required to revise the plan. If the
vendor is unwilling to make the necessary changes, the CEMS may be
dropped from the test program.
Phase II: Selection Criteria for the Endurance Test
The Agency will select CEMSs for participation in the long-term
endurance test based on: (1) performance of the CEMS during the
demonstration test in terms of ability to meet the performance
specifications [75%]; and (2) maintenance requirements based on vendor
information and experience gained during the demonstration test [25%].
V. Disclaimer
Neither acceptance by EPA for participation in this demonstration
nor successful completion of the demonstration shall guarantee that EPA
or any other federal agency or government entity shall accept any
instrument, or related procedure or technology, or any portion thereof,
for the purpose of the measurement of emissions from any regulated
facility.
