CTC Co-Chair, OAQPS

     What s in a name?  Well, most of us seem very comfortable with
the name  Control Technology Center  (CTC), but our friends in
Pollution Prevention (P2) have raised an issue.  It seems that
 control technology  is not an  in  or  politically correct  term. 
The CTC has never differentiated between controlling air pollution
(or preventing it) at its source and treating a gas stream prior to
emission.  We strive to provide information on all feasible
options, whether they re P2 methods or add-on controls.  Today,
however, the  in  term is P2.  Since the CTC has embarked on an
effort to better emphasize its P2 capacity, especially with respect
to small businesses, those that are sensitive to the  correctness 
issue are encouraging the CTC to change its name.  So, if you have
any ideas for a new name for the CTC, please let us know.  My
preference would be to retain CTC in the new name for continuity
and to sustain our current level of recognition, but we are open to
all suggestions.  Send your idea(s) to me on the CTC BBS or just
call the HOTLINE.
     It s not to soon to start thinking about your 1995 CTC project
needs.  Fiscal year 1995 begins for us in October.  That s when
we ll again have funds available to assist you.  Budgets are very
iffy things in times of reform and deficit reduction.  You would be
wise to get your requests in early.  (HINT: Co-sponsored projects
that share responsibility and resources were looked on very
favorably by the Steering Committee last year.  I expect the same
situation in 1995.)  So, get your request in early!  The September
14, 1994, CTC Steering Committee meeting will be our first
opportunity to discuss 1995 projects.  If you want your proposal
discussed at that meeting, you need to submit it as soon as
possible.  You can do that by writing the CTC or putting a detailed
project suggestion on the CTC BBS.  Call the HOTLINE and ask for
Chuck Darvin or me if you would like to discuss a possible project.
     It is a typical hot and humid summer in the Carolinas.  To
keep cool and enjoy some of the water sports in the area, I finally
broke down and bought a used boat.  The boat is a lot like me - a
little older than I care to admit and rough around the edges, but
still functional with enough get up and go when needed.  It helps
me keep cool, especially after wrestling with proposed budget cuts,
rerganization, and EPA streamlining.  The current turmoil at EPA is
a lot like riding the inner tube I tow behind my boat.  There are
a lot of rumors bouncing you around, and you just try to hang on;
however, in the Federal bureaucracy, the goal is to ride the wave
called  streamlining government  or drown in its wake.  Riding and
flipping the tube in the wake of my boat is a lot more fun and
refreshing.  The buy out and early retirement plans being offered
to reduce the Federal work force are sounding better every day.
     Enjoy the NEWS and keep cool.  See you in October!

Evaluation of Emissions from Paving Asphalt

By Bobby E. Daniel
CTC, AEERL

     The CTC has completed a study to identify specific pollutants
emitted from paving asphalt. A significant environmental impact
associated with asphalt paving is the air emissions of contaminants
such as polynuclear aromatic hydrocarbons (PAHs), as well as
volatile organic compounds (VOCs) and particulates. Some of these
pollutants have been identified as contributors to the
photochemical smog problems in parts of the U.S.  Testing included
two types of asphalt used in the paving process: an AC10 grade
asphalt hot mix and an AC10 grade asphalt hot mix with a crumb
rubber additive. The U.S. Intermodal Surface Transportation
Efficiency Act (ISTEA) requires States to use crumb rubber from
recycled tires as an additive for paving asphalt. Crumb rubber is
defined as  scrap tire rubber that has been processed to particle
sizes usually less than 9.5 mm in diameter.  It has been estimated
that approximately 240 million waste passenger car and truck tires
accumulate annually in the U.S.  The need to dispose of these tires
provides a strong incentive for the use of rubber additives in
paving asphalt. 
     Emissions were measured from a static layer of asphalt
maintained for several hours near the temperature that would likely
be encountered during an actual paving operation. Specific
volatile, semi-volatile, and particulate bound organic samples
(including PAHs in Table 1) were targeted for analysis.  These
compounds were chosen due to their demonstrated carcinogenicity in
animals. In addition, Continuous Emission Monitors (CEMs) were used
to analyze for carbon monoxide (CO), carbon dioxide  (CO2),
nitrogen oxide (NO), sulfur dioxide (SO2), and total hydrocarbons
(THCs). Samples were also analyzed for total particulate matter
(PM), PM10, and particulate-phased lead.
     The samples of paving asphalt were heated in a specially
designed vessel in AEERL s Open Burning Simulation Test Facility at
EPA s Environmental Research Center (ERC) in Research Triangle
Park, N.C.  The temperaure of the asphalt was controlled at between
157 and 1620C  (314 and 3230F) with a maximum temperature of 1770C
(3500F).  The analysis of these samples revealed statistically
significant emissions of seven of the targeted PAHs (asterisked in
Table 1).  Six VOC compounds were detected: benzene, ethyl benzene,
m,p,-xylene, o-xylene, toluene, and ethyl acetate. CO, CO2, NO, and
SO2 monitors did not reveal any emissions of these compounds. The
THC concentrations appeared to increase and decrease in response to
the slight variations of asphalt temperatures. 
      A comparison of the total particulates and PM10 results
indicates that the majority of PM produced was less than 10Fm in
diameter. Only one test showed a particulate-phase lead
concentration greater than three times the facility blank samples.
Although some statistically significant differences were found
between the emissions from the asphalt materials tested with and
without rubber (Table 2), these differences were not in general
dramatic.  
     This study did not attempt to simulate the physical agitation
undergone during the course of its application by automated road
construction equipment. In addition, pilot scale studies are never
perfect simulations of full scale processes. Despite these
limitations, the estimated emissions values appear to be one of the
best available starting points for modeling exposures to asphalt
air emissions. The reader is cautioned not to use the estimated
emissions data provided to model exposure since the reported air
concentrations may not be directly applicable to all situations. 
A report on this study should be available from the CTC in August,
1994.

BLIS Odds and Ends

By Jo Ann Kerrick
VGYAN


1994 Compilation Update
     The 1994 supplement to the RBLC Compilation of Control
Technology Determinations has just gone to press, but the
electronic version of this year s supplement is available now on
the BLIS BBS in the Downloading section.  The BBS gives you timely
access to this volume and lets you download just the sections that
you are interested in.  Choose from Appendix F and G summary
information, or select the detailed Appendix H, with complete
listings on 133 new determinations added to the data base this
year.

What Else Is New?
     The 1994 RBLC Compilation is not the only thing that s new on
the BBS.  There is on-going effort to update the electronic
documents on the BBS.  The Informational Flyer and User s Guide are
updated semiannually.  And each quarter, BLIS articles from the CTC
NEWS are added to the BBS.  Just browse through the list of files
in the Downloading section, and look for any new files that you
might be able to use.  (New or revised files are added to the
bottom of the list.  Just check the dates).
     Another addition is the BLIS Road Map, a menu-driven guide to
using the BBS and the BLIS data base.  Select from a brief list of
topics, and then view a one- or two-screen description of how that
feature works in BLIS.  We hope the Road Map helps new users learn
their way around BLIS quickly and alerts old pros to features that
they may have missed.
     Lastly, BLIS now supports five simultaneous users.  Hopefully,
this upgrade will make it easier to get the information you need
from BLIS, when you need it.

Setting the Standard
     The control technology information in BLIS comes from permits
issued all across the country.  State and local regulations often
specify emission limits in different units.  These permitted limits
are the primary emission limits found in BLIS and may be entered in
whatever units the permit specifies.  To allow users to compare the
effectiveness of different control technologies, BLIS also has
standard emission limits.  These limits must be entered in the
standard units for that process and pollutant.  The RBLC staff has
established standard units for internal and extrnal combustion
processes and other processes.  As applicable federal regulations
are reviewed, standardized emission units will be established for
more processes.  
     When you are adding a determination to BLIS, only use the
standard emission limits if standard units have been established
for that particular process.  Feel free to use the alternate
emission limits, but please only put standard units in the standard
units field.  The standard units are used in the Ranking Report,
which presents a rank order listing of pollutant emissions. 
Incorrect standard units exclude determinations from the Ranking
Report.  Missing standard emissions make the Ranking Report less
complete.

Preview of Coming Attractions
     Beginning this summer and continuing into early 1995, the RBLC
staff will be reevaluating the BLIS data base.  Prompted by
recommendations of the New Source Review Reform subcommittee, the
goal of this effort is to eliminate extraneous information, making
the system more efficient and data entry less burdensome.  The
staff also plans to revise the BLIS screens and, where possible,
incorporate help lists or other options to make the system easier
to use.  Watch the BBS for more details as this task progresses.

Oil Suppression of PM at Grain Elevators

     The CTC Report  Oil Suppression of Particulate Matter at Grain
Elevators,  EPA-453/R-94-049 is now available.  This report
provides summary information on oil suppression technology based on
existing data.  This technology appears to be very promising and
attractive from both an environmental and cost perspective.  Its
relatively low capital cost and simplicity make it especially
attractive to small country elevator operators.  However, available
test data are inadequate to determine emission factors or overall
system effectiveness.  You can order or download a copy of this
report from the CTC BBS, or you can call the CTC HOTLINE.
     Because many country elevators are small businesses, the
Federal Small Business Assistance Program (SBAP) has made funding
available to test oil suppression at grain elevators.  The SBAP,
CTC, Emission Measurement Technical Information Center (EMTIC) and
the Clearinghouse for Inventory and Emission Factor Information
(CHIEF) are working with the National Feed and Grain Association
and the State of Nebraska to identify test sites and develop a test
protocol.  We expect that definitive emission factor and efficiency
information for oil suppression technology at grain elevators will
be available in early 1995.  Read the CTC NEWS for updates on
status and availability.

CTC EXPERT:  ELAINE MANNING

By Lisa Florer
Acurex Environmental Corporation

     What s the Este Lauder makeup representative doing at OAQPS? 
No, she s not trying to make over the Chemicals and Petroleum
Branch group; instead, she s developing and writing wastewater
control technology regulations.  Elaine Manning, a member of the
Petroleum Section of the branch, is the CTC s expert in wastewater.
     Elaine, a native of Raleigh, earned a bachelor s of science in
Clothing Design and Merchandising from the University of North
Carolina at Greensboro in 1976.  She took a job with Miller &
Rhodes department stores and embarked on a retail career that
lasted for 10 years.  Elaine started as a Department Supervisor and
quickly worked her way up to a Personnel Manager, then to a
Merchandise Manager, and finally to an Operations Manager for two
stores.  Although she was successful in her career, Elaine says she
became somewhat discouraged with the retail industry and began
attending courses at North Carolina State University.  At the same
time she was taking classes, she worked as an Este Lauder Training
and Promotional Representative.  By 1990, Elaine had earned a
bachelor s of science degree in Civil Engineering.  She interviewed
with Susan Wyatt (Chemicals and Petroleum Branch Chief) on campus
in the summer of 1990 then visited the Mutual Building and
interviewed with K.C. Hustvedt the section Chief for the Petroleum
Section.  Impressed by the people in the group and the potential
work, she accepted a position as an environmental engineer with
EPA.
      The demands of the 1990 Clean Air Act Amendments (CAAA) led
to an increase in the workload for OAQPS.  Elaine was one of the
first hired to help with the increased responsibilities resulting
from the CAAAs.  Her first project was to help develop the
Industrial Wastewater Control Techniques Guideline (CTG).  The CTG,
along with a later project the Industrial Wastewater Alternaive
Control Technology document (ACT) provide guidance to States and
industry for air emissions from wastewater control.  In addition,
she helped complete the wastewater portion of the Hazardous Organic
NESHAP (HON), which was published in final form in April.
     Because of her involvement with the CTG/ACT and the recent
release of the HON, Elaine s involvement with the CTC Hotline has
dramatically increased.  The new regulations set forth in the HON
have forced people to find out how they can comply, and as a
result, she says that CTC calls about the wastewater regulations
alone have increased three times in numbers in the last six months.
     Elaine s work with air emission factors for wastewater for the
pulp and paper industry has allowed her to do some traveling.  She
represented the Petroleum Section Pulp and Paper team at on-site
testing locations in North Carolina and the West Coast.  Her most
memorable experience was the three weeks she spent at several pulp
and paper mills in Washington state.  Elaine says that believe it
or not, she and the team she was with got used to the overwhelming
plant odor, it was the black, gunky paper pulp that dripped on them
throughout the day that took some getting used to.  
     When she s not working on wastewater control guidelines,
Elaine is involved with computer modeling.  Elaine is working with
models that are used to estimate air emissions from wastewater in
collection and treatment systems.  
     Elaine beams when she talks about her drastic career switch
from retail to engineering.  She says that although her job is very
rewarding, it s the people she works with that make the difference. 
Elaine still finds time to read and often takes off for the beach
on weekends anything to avoid having to go to the mall!

PENNSYLVANIA S AIR QUALITY IMPROVEMENT FUND

By Richard Segrave-Daly
Pennsylvania Small Business Ombudsman

     In amending Pennsylvania s Air Pollution Control Act to
reflect elements of the Clean Air Act Amendments of 1990, the
Pennsylvania legislature established the Air Quality Improvement
Fund (AQIF).  This program will provide low interest, direct loans
to eligible small businesses (as defined by the CAAA) to reduce or
eliminate air pollution by purchasing control equipment or changing
existing processes.  Three million dollars have been transferred to
the AQIF from the Hazardous Site Clean-Up Fund.
     The application is in two parts.  Part I, the Determination of
Eligibility, is used to compute emissions and describe what is to
be purchased if the loan is approved.  Eligibility is determined by
the Department of Environmental Resources, and is based upon
whether the applicant company is emitting a controlled pollutant or
air toxic, and whether the company s intended actions are likely to
solve the problem.  Once a company is determined as eligible, Part
II of the AQIF application, (the financial information) is
forwarded to the Department of Commerce for analysis of credit
worthiness and repayment ability.
     The AQIF loans may be as much as $100,000 and are limited to
75 percent of the cost of the control equipent or process change. 
Repayment may be extended to seven years, and the interest rate on
the loan is a very favorable two percent.
     To date, 17 completed applications have been received for
review; nine have been approved for a total of approximately
$339,000.  Most loans to date have been made to dry cleaners and a
few gas stations in the Philadelphia severe nonattainment area.
     We re making every effort possible to promote the program to
individual companies, trade associations, chambers of commerce, and
local economic development organizations.  Over 200 AQIF
applications have been mailed and we expect the pace of completed
applications and approvals to increase substantially in the near
future.
     For additional information, please contact Richard
Segrave-Daly, Small Business Ombudsman, Pennsylvania Department of
Commerce at (717) 772-2889.

CTC Completes Tire-Derived Fuel Combustion Study

By Paul M. Lemieux
AEERL

     Based on numerous requests to the CTC from State and local
agencies, EPA s Air and Energy Engineering Research Laboratory
recently completed a pilot-scale study to examine emissions of
hazardous air pollutants (HAPs) from combustion of tire-derived
fuel (TDF).  The experiments were performed in a rotary kiln
incinerator simulator located in Research Triangle Park, NC.  In
these experiments, TDF (with the wire removed) sized smaller than
1/4 in. was co-fired with natural gas, in amounts up to 20% of the
total fuel input at a variety of feed and combustion conditions. 
Samples were taken to measure volatile organic compounds (VOCs),
semi-volatile organic compounds (SVOCs), metals, and
polychlorinated dibenzo p-dioxins and polychlorinated dibenzofurans
(PCDD/PCDF).  Emissions of carbon monoxide (CO), total hydrocarbons
(THCs),  and polycyclic aromatic hydrocarbons (PAHs) were
continuously measured.
     Results indicate that TDF fired in a steady-state mode will
result in very low emissions of CO, THCs, VOCs, SVOCs, and PCDD/
PCDF.  Metal emissions were also very low, with the exception of
arsenic (As), lead (Pb), and zinc (Zn).  Uncontrolled stack
concentrations of As and Pb were 37.16 and 65.96 Fg/Nm3,
respectively.  Uncontrolled Zn emissions were considerably higher,
at 35,465 Fg/Nm3.  Results also indicate that organic emissions can
increase significantly when TDF is fired in a non-steady mode.  The
continuous PAH analyzer appeared to track transient operation well,
and gave concentration results in the same range as those derived
using EPA standard SVOC sampling methodologies.  The PAH analyzer
appeared to be much more sensitive than the CO analyzer in
distinguishing between different degrees of what would be termed
 good  combustion, and may be very useful for combustion process
control or optimization.
     Emissions were compared to those from combustion of
conventional fossil fuels (e.g., coal, oil) in utility boilers. 
Overall, it appears that, with the exception of Zn, potential
emissions from TDF combustion are not significantly different from
emissions from combustion of conventional fossil fuels when the TDF
is burned in a well-designed and well-operated combustion device.

LITHOGRAPHIC PRINTING ACT DOCUMENT & WOOD FURNITURE MODEL RULE
NOW AVAILABLE THROUGH THE CTC


     The  Alternative Control Technique Document: Offset
Lithographic Printing,  EPA-453/R-94-054, is now available through
the CTC.  This document supplements the draft control techniques
guideline (CTG) announced in the Federal Register on November 8,
1993.  The CTG should not be used alone, but rather in conjunction
with this ACT document.  The ACT provides additional information
that States can use in developing rules based on reasonably
available control technology (RACT).
      APPENDIX B:  PRELIMINARY DRAFT MODEL RULE FOR WOOD FURNITURE
FINISHING AND CLEANING OPERATIONS  is now available through the
CTC.  This appendix is to be part of the CTG now being prepared by
EPA (NOTE: the CTG is not available!).  It presents a model rule
for limiting VOC emissions from wood furniture manufacturing
facilities located in ozone nonattainment areas or in the ozone
transport region.  The model rule is a product of negotiations
among representatives of the wood furniture industry, environmental
groups, States, and the EPA.  It addresses various factors,
including applicability, definitions, emission and work practice
standards, compliance and monitoring, test methods, and record
keeping and reporting requirements that need to be addressed in
writing an enforceable rule.  It also provides information on how
to incorporate an emission averaging program to meet the
requirements of the model rule.  The model rule is for illustrative
purposes only.  States may use alternative approaches that are
consistent with basic program requirements.
     You can order these documents through the CTC BBS or by
calling the CTC HOTLINE.
