This study charac- terizes waste oil (i.e., used crankcase oil), the air quality impacts of combust- ing waste oil in air atomizing space heaters, and the need to adjust Vermont DEC rules governing used oil combus- tion. This study resulted from a request made by the Vermont DEC to the CTC to assist in a study of waste oil re- quested by the Vermont General As- sembly. The DEC planned the project, collected and analyzed waste oil samples, selected facilities to be tested, determined the air quality impact of emissions from waste oil combus- tion, consid- ered the need to change DEC regulations based on study results, and provided overall project management. The CTC provided on- site testing of waste oil combustion units through the Source Characterization Group A in the Emis- sions, Monitoring and Analysis Division, OAQPS/EPA. Waste oil samples were collected from 21 gasoline and diesel mainte- nance facilities and do- it-yourself drop off sites. Analysis of used oil samples revealed higher levels of several contaminants over No. 2 home heating oil. Waste oil test results are pre- sented in Table 1. Note that some of the con- taminants found are the result of perfor- mance additives in the virgin oil and are not necessarily the result of contamina- (continued page 2) AIRWA VES By Chuck Darvin CTC Co-chair, AEERL Greetings from the Co-chair! If you are wondering whether the CTC has had a change in management since Bob Blaszczak usually writes this column, be assured, he just had an attack of writer's cramp this quarter. However, for those of you who are not familiar with its structure, the CTC is divided into two sections, gathering ex- pertise from two Environmental Protec- tion Agency (EPA) sponsor organiza- tions. Bob is the Co-chair from the Of- fice of Air Quality Planning and Stan- dards (OAQPS), responding to your calls regarding regulatory questions and related technology application is- sues. On the other hand, I Co-chair the CTC on behalf of the Air Pollution Pre- vention and Control Division (APPCD) of the EPA Office of Research and Development (R&D). The APPCD group, consisting of research engineers and scientists, responds to calls for technical information and R&D assis- tance. The research side of the CTC can call on the immediate services of four engineers and scientists to address your technical issues. In addition, we frequently call for technical support from the 75 engineers and scientists of the sponsoring research laboratory to conduct studies in a broad range of technical disciplines, especially issues involving air emissions. The R&D side of the CTC has, in my opinion, the most exciting assignments of the two groups. Since most of the technical studies result from your re- quests, they tend to be more practical, with immediate application to yourtech- nical problems. Some examples of successful studies include research in the area of tire burning, and emissions from roofing and road asphalt. At your request, the CTC conducted research into the na- ture of emissions from tire burning, thereby becoming a widely recognized and used authority on the composition and characteristics of the emissions. The documents from our studies on roofing and road asphalt emissions are regarded as widely recognized and used information on pollutants from these sources. As a result of your HOTLINE calls, the CTC developed SIMS (Surface Im- (continued page 3) ------- WASTE OIL COMBUSTION (continued from page 1) tion from use in engines. The majority of samples complied with the constitu- ent and property limits stated in Ver- mont regulations. Stack testing was conducted on five atomizing waste oil furnaces cur- rently in service and one No. 2 fuel oil furnace. A sample of the fuel com- busted at each site during the emission test was also collected and analyzed. Stack emission test results indicated higher levels of contaminants over that of No. 2 fuel oil. Waste oil combustion emission test results are presented in Table 2. These results were modeled to determine compliance with Vermont's ambient air quality standards for the pollutants listed.

The report is divided into two parts. The first part is the report prepared by the DEC for the Vermont Gen- eral Assembly. Part two is the EPA emission testing report for the waste oil fur- naces tested. This report is available on the CTC BBS. To order a hard copy, gov- ernment agencies should call the CTC HOTLINE. Others should call the Na- tional Technical Information Service (NTIS) at 800/553- 6847. 'Arsenic concentrations are not reported due to analytical difficulties with accurately determining arsenic concentrations at the necessary levels. While the laboratory can quantify arsenic concentrations in oil greater than 250 ppb, under the procedures of method 3050 some organic arsenic compounds are lost through volatilization, resulting in poor spike recoveries and the possibility of false negative results. Only one sample had an arsenic concentration >250 ppb and that concentration was reported as >2 ppm.

OIL SUPPRESSION OF PM AT GRAIN ELEVATORS SBAP PROJECT UPDATE SBAP sponsored testing of a grain elevator in Greenwood, Nebraska was completed in August 1994; however, the efficiency of oil suppression technol- ogy was less than expected. Since oil was applied in the leg of the elevator, this result could have been caused by inadequate mixing of oil and grain. Greater efficiencies are anticipated if oil is sprayed during active grain tumbling. As a result, the National Grain and Feed Association, with the cooperation of EPA's Emissions, Monitoring and Analysis Division, SBAP and CTC, will be conduct- By Bob Blaszczak, CTC/OAQPS ing additional tests this summer. The new tests should document the effec- tiveness of oil suppression technology under more optimal conditions. At the Greenwood site with the oil suppression system operating at the typical 25 psi, the test results indicated about 60% efficiency for both PM 10 and total suspended particulate(TSP) when ^Handv Dry Cleaners transferring milo, and 69% and 48% efficiency for PM10 and TSP, respec- tively, when handling corn. With the oil suppression system at20 psi, efficiency remained about the same when han- dling corn, but dropped considerably when handling milo. The SBAP and CTC will keep you advised. Just check the CTC NEWS and CTC or SBAP BBSs for updates on the test results. We hope to have a report based on all valid test results by early fall 1995. E3 CTC News page 4 ------- TECHNOLOGY NOTEBOOK HAP-PRO 2.0, YOU HAVE TO INPUT VALUES By Lyndon S. Cox Senior Environmental Employee A few weeks ago, I got a call on the HOTLINE from a person who had a software problem. The caller had down- loaded HAP-PRO version 2.0 from the CTC Bulletin Board System (BBS), and found that for thermal incineration and catalytic incineration the electrical con- sumption, and therefore the cost of electricity, was being computed as zero. How could this be? First, I contacted the Project Officer and outlined the problem that was en- countered. I noted that electrical power consumption is calculated in the Control Cost Manual (EPA 450/3-90-006) from which HAP-PRO is derived. The Project Officer went to the pro- grammer who encoded the computer program for HAP-PRO. The program- mer proceeded to look into the program and found that the calculation was in- deed present in HAP-PRO. Then the programmer traced the parameters to ensure that they were being entered and computed properly by HAP-PRO. The programmer found that, to com- pute the electrical power consumption, the pressure drop has to have a non- zero value. The pressure drop is found among the parameters of the control device. This value must be entered because there is no explicit default value. Why isthis the case? In the Control Cost Manual, the electrical power con- sumption is given by the equation: 1.17x 10-4 Q Power fan= Where: Powerfan is in kilowatts. Qtotal is the actual flow volume cor- rected for temperature. • P is the pressure drop in inches of water, and has no explicit default value in HAP-PRO. Therefore, the computa- tion assumes a de- fault value of zero. • is the fan and motor efficiency, which has a default value of 60% in HAP-PRO. The power consumption is multiplied by the hours of operation per year and the cost per kilowatt- hour to give the an- nual cost of electricity. That means that a non-zero value for pressure drop must be entered to obtain a non-zero value for the electrical consumption and the cost of electricity. Without actual values, this pressure drop can be estimated. Page 3-55 of the Control Cost Manual gives reasonable values for pressure drop in incinerators and heat exchangers as indicated in the table above. These values are additive. That is, athermal incinerator with a 50% energy recovery by heat exchanger would have a pressure drop of 4 inches of water in the incinerator itself plus a pressure drop of 8 inches of water in the heat exchanger. The overall pressure drop would be 12 inches of water. However, the total pressure drop is required, which also includes the pressure drop in the duct work bringing flow to the incin- erator and taking flowfrom the incinera- tor to the atmosphere. One example problem in the Control Cost Manual uses a total pressure drop of 23 inches of water. The basis for pressure drop in duct work is discussed in Chapter 10 of the Control Cost Manual, which is the Third Supplement to the Control Cost Manual. This pressure drop consists of losses through straight ducts, fittings, branch devices, venae contractae, and stacks. The pressure drop across duct work for the particular incinerator can vary widely, and must be determined for each installation. Therefore, we can refer you to either Chapter 10 of the Control Cost Manual or a good Me- chanical Engineering Handbook to cal- Equipment Type Thermal Incinerator Catalytic Fixed-BEd Incinerators Catalytic Fluid-Bed Incinerators Heat Exchanger Heat Exchanger Heat Exchanger Energy Recovery, % 0 0 0 35 50 70 P, inches of water 4 6 6-10 4 8 15 culate the pressure drop for the duct work in your installation. Be aware that, when using HAP- PRO, you must enter a value for the total pressure drop across the incinera- tor and its duct work to obtain an accu- rate power consumption. The cost of electricity, and therefore the annual op- erating cost, depend on this value. But please remember, the value computed is only as good as the input data. Fortunately, the calculator is present in HAP-PRO version 2.0 to help you do any necessary calculations. Control Technology Center The CTC NEWS is a quarterly publication of the U.S. EPA's Control Technology Center (CTC). The CTC is an informal, easy-to-use, no cost, technical assistance service for all State and local (S/l) air pollution control agency and EPA Regional Office staffs.

V _ CTC News page 5 ------- RACT/BACT/LAER CLEARINGHOUSE U P D A T E By Jo Ann Kerrick, ViGYAN RBLC EMPHASIZES POLLUTION PREVENTION Recent EPA policy and rules re- garding air pollutant emissions have increasingly emphasized "pollution pre- vention" (P2) as the preferred alterna- tive or, at least, a complement to add-on control equipment. P2 refers to process changes, changes in raw materials or fuels, and other methods designed to prevent or reduce pollution at the source. The RACT/BACT/LAER Clear- inghouse (RBLC) has just completed a projectto bring it up-to-date with respect to P2 and to enhance the productivity of data base queries related to P2 informa- tion. First, to highlight P2 information within the data base, several data fields at the pollutant level have changed. A logical field was added to indicate what each permit requires for a specified pollutant: * No P2 or add-on controls * Add-on control equipment (hardware) * Pollution prevention methods * Both add-on controls and P2 methods. Also, asingle, longercharacterfield was added to hold narrative information about required P2 methods and add-on controls. This single data field replaces separate control equipment and pro- cess modification data fields. The new field allows room for more detailed de- scriptions of prevention and control methods and should make the RBLC data base more helpful to users. Both new logical and character fields are searchable. Pollutant data screen and the download reports have been revised to accommodate new data fields. The second part of our effort was to review all determinations in the current database, paying particular attention to information about P2. Information in data base fields labeled "Control Equip- ment" and "Process Modification" was transferred to the new logical and char- acterfieldsdescribed above. Wherever possible, standardized terms were used to insure that text searches can suc- cessfully find all the applicable informa- tion. For example, the phrase "FUEL SPEC", for fuel specification, now ap- pears in all determinations which re- quire specific fuels (low sulfur coal or fuel oil, for example). We also evalu- ated the completeness and technical consistency of information about P2 methods. For those determinations in which existing information was either completely missing or of questionable applicability to the specific process, we contacted the submitting state or local agency to obtain correct and complete information and added it to the data base. Hopefully these changes will give users easieraccessto P2 information in the RBLC data base. Submitting agen- cies should also find that the longerdata field makes it easier to describe P2 and control methods required atthe facilities they permit. EXPANDED HELP FOR RBLC If you're a long-time user of the RBLC, you may consider yourself an expert who doesn't need any help. However, you might want to look at these recent upgrades to our on-line help. We've added a pick list of SIC codes in both Query and Edit. Also, we've revised the Edit help to indicate which fields are required before a deter- mination can be promoted from the tran- sient data base. We're only trying to help! NEW ADDITIONS TO REGULATION DATA BASE The RBLC regulation data base (REGS) now lets you scan all rules in the data base — without doing a search. A new "Browse" option, avail- able from the REGS main menu, lets you view the complete list of regula- tions. The list is sorted by affected facility name so that you can readily find rules of interest to you. In addition to viewing the rules on-line, you can mark selected rules and download them to your local PC. Choose a regulation from the list, goto the regulation data screen, and mark the rule fordownloading. Re- peat this process for as many rules as you like, and then choose a download format. Use Browse if you only want to view rules on-line or if you are just interested in a particular affected facil- ity. It's quickerthan building a query and searching the data base. When you need to access rules for certain process types or pollutants, Query is still the most efficientway to locate information. REGS contains summaries of fed- eral regulations enacted in response to the Clean Air Act and Amendments (CAAA). For newer rules, the complete text of the regulation is available on the CAAA BBS. To help you find this infor- mation, the regulation data base now includes the names and locations of files on the CAAA BBS. Rules available on the TTN are flagged with a "C" in the affected facility list, and the CAAA BBS file information is available in a pop-up box on the process list screen. CTC News page 6 ------- CTC EXPERT KELLY LEOVIC By Heather Sigmon, Acurex Environmental If you call the CTC HOTLINE with a question about Indoor Air Quality, you may find yourself in a discussion with Kelly Leovic. Pleasant and easy to talk to, Kelly will give you all the information you need and more about her area of expertise at EPA/APPCD's Indoor Air Branch. Her current projects include identifying and characterizing sources of indoor air emissions from office equipment such as copiers and printers, developing pollution prevention tech- niques and guidelines for formulating less toxic aerosol consumer products, and publishing a biannual newsletterfor the Air Pollution Prevention & Control Division entitled "Inside IAQ." A native of Buffalo, NY, Kelly ar- rived in Durham in 1980 to attend Duke University without having ever seen Durham or Duke. Fortunately for the EPA and the numerous community af- fairs Kelly participates in, she fell in love with the Triangle area and has been here since, with the exception of a year spent working in Colorado. After earn- ing a Bachelor of Science in Geology and Math in 1983, Kelly continued on at Duke, earning a Masters of Science in Civil and Environmental Engineering in 1985. Additionally, in 1992, Kelly re- ceived an MBA from the Fuqua School of Business at Duke University, a de- gree which she feels has made her a more well rounded person. Rest as- sured though, Kelly has no future plans to leave the EPA and climb the corpo- rate ladder! Kelly began working for APPCD in 1987, doing mainly field work for the Radon Mitigation Branch. Kelly's dili- gence and hard work earned her a bronze medal for scientific leadership in reducing significantly elevated levels of radon in two schools in Nashville, Ten- nessee. This and other radon work ultimately led to the publication of "Ra- don Prevention in the Design and Con- struction of Schools and Other Large Buildings," a technical guide for archi- tects and engineers, as well as an infor- BUS BBS CHANGES NAME TO RBLC BBS! No, it's not the new math. The familiar name of the BACT/LAER Informa- tion System (BLIS) is changing! We'll now be known as the RACT/BACT/ LAER Clearinghouse (RBLC). The name change is long overdue since the Clean Air Act Amendments of 1990 added RACT to our name in November 1990. We had resisted the change fearing that no-one would recognize us. But, they say change is good, so I suppose this could be a good thing! Just be sure to look for us under our new name, the RBLC. (Remember, the TIN technical area list is in alphabeti- cal order, so our name will be fur- ther down. Really! It's still us! Check it out and see!) RBLC ii BLIS mationalguideforschoolprincipalsand administrators to learn the importance of radon prevention. In 1992 Kelly moved over to the Indoor Air Branch where she began her work with office equipment and aerosol emissions. Kelly has participated in several EPA-sponsored educational outreach programs. Through the EPA Scientist Teacher Partnership, Kelly would go to an area elementary school once a month to teach the classes of a teacher shewasassignedto. Shehasalsobeen part of a one-day science fair program for local high school students. In addition to all her other work for the Indoor Air Branch, Kelly is organiz- ing a symposium on Engineering Solu- tions to Indoor Air Quality Problems to be held in late July. She was also on the planning committee of the EPA in Re- search Triangle Park, for the celebra- tion of the 25th Anniversary of Earth Day. One may wonder how, with so much to do, Kelly has time to answer CTC calls, but she is never too busy to help someone needing information. Kelly sees answering CTC calls as a great way of passing on information and another way she can help educate oth- ers on issues regarding indoor air. Kelly, her husband Todd, and new baby Cody love to travel and are hoping to take a trip to the Virgin Islands some- time this summer. It sounds like a great way to relax.
