inside US ENVIRONMENTAL PROTECTION AGENCY-WVSHINGTON, DC 20460 • JUNE 1973 Lab Shifts Will Involve 155 Employees Shifts of research operations among seven EPA laboratories and three National Research Centers have been announced by Assistant Administrator Stanley M. Green- field. The moves, now in progress, will be completed this summer and will affect approximately 155 perma- nent employees. The transfers are being made, Greenfield said, to consolidate and strengthen the Agency's research and development work in water supply, marine water quality, pesti- cides, and radiation. Operations that have been carried out in re- mote and sometimes unsafe facili- ties are being moved to the appro- priate NERCs or, in one case, to a satellite laboratory that will be enlarged with a new building and facilities costing $2.8 million. A summary of the program shifts, EPA's Research Reorganized Into 4 Operating Components A reorganization of EPA's re- search office and some shifting of headquarters personnel and titles were announced recently by Acting Administrator Robert Fri. Renamed the Office of Research and Development, the new organi- zation remains under the direction of Assistant Administrator Stanley M. Greenfield. The basic organization of the four National Environmental Research Centers and their field laboratories is not affected. "In changing the old Office of Research and Monitoring," Green- field said, "we have tried to fit our headquarters components more closely to our actual research and development functions and hence to become more responsive to EPA's overall needs." Four main operating units were created: • The Office of Program In- tegration, under Dr. Leland D. Attaway, charged with "assur- ing that research and engineer- ing strategies match and are re- sponsive to the Agency's goals." • The Office of Environmental Engineering, headed by Albert C. Trakowski, to manage the Agency's research, development, and demonstration programs in pollution control. • The Office of Environmental Sciences, under Dr. Herbert L. Wiser, which will develop cri- teria for environmental quality standards and identify new prob- lems. • The Office of Monitoring Systems, headed by Willis B. Foster, to work on equipment, techniques, and systems for measuring and handling environ- mental data. Two smaller components report- ing directly to Greenfield are the Office of Program Management headed by Dr. David G. Stephan, and the Washington Environmental Research Center with Dr. Larry Ruff as acting director. The latter will continue the analytical and exploratory work of the old Envi- ronmental Studies and Implementa- tion Research Divisions. with the approximate number of positions involved in each, follows; Water supply research programs are slated to go to NERC-Cincin- nati from the Northeast Water Sup- ply Research Laboratory, Narragan- sett, R.I., 20 positions; from the Gulf Coast Water Supply Labora- tory, Dauphin Island, Ala., 16 posi- tions; and from the Northwestern Water Supply Laboratory, Gig Har- bor, Wash., 12 positions. Part of the marine water quality work now performed in leased fa- cilities at West Kingston, R.I., will be moved to nearby Narragansett this summer, and EPA plans to ex- pand the Narragansett facilities with a new $2.8-million building to accommodate the entire program now at West Kingston. The Narra- gansett laboratory will be renamed the National Marine Water Quality Laboratory and will remain a NERC-Corvallis affiliate. Pesticide research programs will go to NERC-Research Triangle Park, N.C., from the Primate and Pesticides Effects Laboratory, Per- rine, Fla., 55 positions, and from the Chamblee Toxicology Labora- tory, Chamblee, Ga., 25 positions. EPA is leaving Chamblee to make more room for DHEW operations there. Radiation research at the Eastern Environmental Radiation Labora- tory, Montgomery, Ala., will be moved to NERC-RTP and NERC- Las Vegas. Health effects research, 17 positions, will move to North Carolina, and monitoring-quality assurance work, 10 positions, will move to Las Vegas. The Office of Radiation Programs will take over the remaining field activities (as opposed to research (Continued on page 3) ------- Washington Commuters Hire Own Bus A group of EPA headquarters employees have found an unusual way to get back and forth to work each day. They charter a bus. It started when the Radiation Programs Office was moved en masse late in April from suburban Rockville, Md., to downtown Wash- ington, 16 miles away. Many em- ployees who live in the Rockville area suddenly had tough commuting problems: parking space at Water- side Mall is costly and scarce, the rush-hour traffic formidable, and public bus service was slow and crowded and required a transfer. But Jean Maguire, a secretary in the office of William D. Rowe, deputy assistant administrator for radiation programs, had a brilliant idea and the gumption to carry it out. She canvassed her colleagues before the move to find people who did not want to battle the Washing- ton traffic twice each day. She found enough to justify chartering a special bus. The service has been operating since the second day the RPO peo- ple were in their new quarters in the East Tower of EPA's Waterside Mall headquarters. The riders now include a number of Water Pro- SAILING TO WORK Water-borne commuting be- tween Alexandria and EPA headquarters was launched three weeks ago by Robert Greenspan, analyst in Air and Water Pro- grams. Two to four persons have been taking the 10-minute trip on the Potomac each day, he said, and there is room for more. The dock is three blocks away. The cost: $1.50 per day. The boat is owned by Green- spun and three AWP colleagues, Harry Pitts, Denis Daniel, and Charles Marks, who still work at Crystal Mall on the Virginia side and can't yet sail to work. —photo by Ernest Bucci Shirley Landsman, James Hardin, and Joseph Logsdon board the bus— while Wayne Hansen checks off their names—for daily charter trip. grams Office personnel who were transferred in May from the Crystal Mall Building in Arlington. The group now has about 50 subscribers, and the bus is filled. Actually, it is slightly "oversold." On any given day some regular riders will be absent on leave, or sick, or traveling. So there have not been many standees during the seven weeks the bus has been op- erating. The bus makes two pickup stops each morning: at 6:50 in Gaithers- burg, five miles north of Rockville, and at 7:10 at a shopping center in Rockville, near the former Radia- tion Office location. Volunteer checkers try to make sure that everyone is accounted for. Then the bus makes a non-stop, express trip to Southwest Washington, ar- riving about 7:50. The return trip starts at 4:30 or soon thereafter. The service is informal and depends on volunteer leaders to collect money, keep records, and count noses. Besides Ms. Maguire, these leaders have included Harold Peterson, David Lutz, Paul Magno, Carl Miller, Richard Chiacchierini, and James Gruhlke. The cost is calculated to cover the bus firm's charge of $80 per day for the two trips, divided evenly among the subscribers. The current assess- ment is $35 per month, and one- time, one-way riders are charged $1.50 per trip if space is available. The monthly charge is about equivalent to public bus fares, but it provides faster, more convenient service. The group has built up a small cash reserve, Peterson said, to assure that bills are paid promptly and to meet contingencies. There are indications that other bus charter groups may be orga- nized soon to serve EPA employees in other suburban areas. A list of seven charter bus firms, their costs and franchise limitations has been distributed to all Agency employees in the Washington area. Donald J. O'Bryan Jr. of the Office of Research and Develop- ment, says he has 20 to 25 persons interested in a charter bus that would start in Olney, Md., and make a couple of stops nearer the city. — 2 ------- LAKE SURVEY FLIERS HELP IN FLOOD WORK An EPA helicopter team on the National Eutrophication Survey recently worked over a weekend to help with flood con- trol and relief operations along the Mississippi River in southern Illinois. Pilots Tommy Bohannan and William Hinkle and Crew Chief Frederick Pike flew 14 missions on Saturday and Sunday, April 28-9, to deliver food and water to communities isolated by the flood, to survey levees and dikes, and to make photographs and contour maps of the disaster areas. The fliers and other member's of EPA's lake survey operation were working out of Dayton, Ohio, when the flood came. The adjutant general of the Illinois National Guard, whose members have been assisting in the survey, accepted EPA's offer of a heli- copter and crew to help in the flood emergency. The crew flew the pontoon- equipped aircraft about 300 miles to the National Guard com- mand post at Grafton, 111., 30 miles upstream from St. Louis, and put their services at the dis- posal of flood control officials. EPA and Tunis Seek to Rescue One of World's Dirtiest Lakes A three-year cooperative pro- gram aimed at saving one of the world's most polluted lakes was launched this month in Tunisia, North Africa, by EPA and the Tu- nisian government. Herbert Quinn of EPA's Office of International Activities and Thomas E. Maloney of the Pacific Northwest Environmental Research Laboratory spent a week in Tunis, the capital city, setting up techni- cal procedures for the project with Tunisian officials. Maloney, who heads the lake eu- trophication research work at PNERL in Corvallis, Ore., will be EPA project officer for the joint study, which will be underwritten by United States credits in Tunisian dinars equivalent to $250,000. Object of the work, which will be performed by Tunisian scientists with technical assistance from EPA, is to alleviate the pollution prob- lems of Lake Tunis, a shallow, lagoon-like pond that has received sewage and runoff waste water from Tunis and other cities for many centuries, probably back as far as the ninth century, B.C., when Car- thage was built near the present site of Tunis. The lake used to have an outlet to the Gulf of Tunis, but now is a land-locked pond 45 square kilome- ters (11 square miles) in size but only one or two meters deep. Dur- ing the cooler months of the year immense growths of algae flourish, along with commercially valuable fish and shellfish, but in summer there are frequent and severe fish kills. Sewage discharge is a signifi- cant factor in this destructive cycle. Dr. Abderrazak Azouz, director of Tunisia's National Technical In- stitute of Oceanography and Fish- eries, is coordinating the project for his government. Principal project scientist will be Habib Ben Alaya. Several engineering and biologi- cal studies of Lake Tunis have been made during the last decade, and the Tunisian government is anxious to eliminate noxious odors and to increase and stabilize fish produc- tion. The new joint study will focus on the eutrophication problems of the lake, evaluating the potential benefits of diverting the sewage in- put, and estimating the rate and extent of recovery of the lake after such diversion. EPA experts hope the study will lead to development of a predica- tive model that could be adapted for use with other lakes that are in advanced stages of eutrophication. Laboratory Shifts Will Involve 155 Employees (Continued from page 1) and development) at Montgomery, which will become the focus of ORP's field operations east of the Mississippi. The transfers will bring presently scattered R&D programs to the EPA research centers that are di- rectly responsible for their manage- ment, Greenfield said. The shifts are also expected to reduce operat- ing costs. The cost factor is particularly important, he said, in the case of facilities housed in old buildings un- suitable for hazardous laboratory operations. Severe safety problems exist at the Perrine laboratory, and, to a lesser degree, at Chamblee and Montgomery, and it would be pro- hibitively expensive to repair and upgrade them or construct new facilities to meet the Agency's safety standards and the require- ments of the Occupational Safety and Health Act. The Dauphin Island facility will be returned to DHEW for use in the Food and Drug Administra- tion's shellfish sanitation work. The Gig Harbor laboratory will be transferred to a new facility to be constructed about IS miles away at Manchester, Wash. This build- ing, containing 20,000 square feet of floor space and costing $1.8 mil- lion, will combine a laboratory staff for Region X and a marine re- search program. "We plan to implement the trans- fers so as to cause minimum dis- turbance to ongoing scientific work," Greenfield said. "All em- ployees involved will be given every consideration and assistance in making a smooth transition, in accordance with Agency and Civil Service regulations." ------- 4,000 Kids See Gulf Breeze Laboratory More than 4,000 school children trooped through the Gulf Breeze Environmental Research Labora- tory last month to learn firsthand about the myriad forms of marine life in the waters around the labora- tory on Sabine Island, Florida, near Pensacola. In three tours a day over a two- week period, busloads of fourth- graders from the public schools of Escambia County came to the labo- ratory, heard brief lectures on the marine environment (Do you know the difference between a bay and an estuary?), and were shown some of the laboratory's current work on the effects of pesticides. The hit of the annual open house —available only to kids and not to the adult public—was an array of outdoor aquariums set up on a dock area, where a great variety of ma- rine creatures were displayed at fourth-grade eye level. These in- cluded a "petting zoo"—special tanks containing marine specimens that the visitors were encouraged to touch and handle. If you haven't petted a baby squid, you haven't lived. "Fourth graders are at an ex- Dr. Delbert Wayne tells a group of Florida fourth-graders which aquariums are for looking and which are "petting tanks" for feeling and handling. cellent age for developing an aware- ness for the environment and its resources," said Dr. Nelson R. Cooley, fishery biologist at the lab. "Concern for preserving the earth's natural resources must begin with the young," he said. "By con- centrating on one grade we hope that every child in Escambia County schools will have visited our lab at least once during the elementary school years." The aquarium tanks set up under the direction of technician Dana Tyler, were kept constantly sup- plied with estuarine water from Pen- Dana Tyler, left, shows the visitors one of the more crabby specimens.

Each morning during the two weeks, the Dolphin sailed out to resupply the exhibit tanks with shrimp, crabs, scallops, squids, and dozens of varieties of plain and fancy fish. Some specimens were barred from the "petting" tanks, in- cluding the scorpion fish, which has a venomous sting, and crabs with working claws. In addition to the fourth graders' tours on week days, the lab stayed open for several tours for troops of Boy and Girl Scouts on Saturday and Sunday, May 5 and 6. Laboratory Director Thomas W. Duke said that next year at least one day of the exhibit period would be open to the public. PUBLIC AFFAIRS POST GOES TO ANN L. DORE Ann L. Dore, former director of public relations for the Committee for the Re-election of the President and press secretary for the Inaug- ural Committee, last month was named EPA director of Public Affairs, succeeding Thomas T. Hart who resigned in January. Ms. Dore had previously been a public relations consultant to a number of firms in New York City, including Heublein Inc., Interna- tional Salt Co., Greenleaves Farms, Inc., Buitoni, Inc., Lederle Labora- tories, and the International Cook- ing School. In 1970, she was coor- dinator for Dr. John McLaughlin's campaign for the U.S. Senate from Rhode Island. Born in Newark, N.J., 31 years ago, Ms. Dore was raised in Chat- ham, N.J., and was graduated from Marymount College, Tarrytown, N.Y. She studied at the University of London in 1961-62. She was supervisor of commercial schedul- ing for the ABC television network for two years and director of alumnae relations for Marymount College for three years. In 1965, she received the Outstanding Young Woman of America Award. Volleyball Players Win Sports Award Three members of the volleyball team at the Northeast Water Sup- ply Research Laboratory, Narra- gansett, R.I., recently received sports awards from the Presiden- tial Commission on Physical Fit- ness. Certificates, signed by President Nixon, went to Edward Katz, Stefan Mulawka, and Joseph Adriano. The lab's volleyball team has been playing five times a week for two years, Katz said, and his doc- tor is pleased with the drop in his cholesterol level. ------- Advice to Utah: Stay Off 'Hot' Tailings Land on which uranium mill tailings have been dumped is not a suitable place to build a race track. That was EPA's advice June 7 to Utah officials considering what to do about a proposed automobile race track just southwest of the Salt Lake City limits. The land, formerly leased by the Vitro Chemical Co., was used for the disposal of sand-like, slightly radioactive waste from the firm's uranium mining operations, accord- ing to Paul B. Smith, regional ra- diation representative in EPA's Denver office. The company has long since ceased uranium process- ing, and about 900,000 tons of tail- ings have just been sitting there. Early this year a private develop- ment corporation started leveling the piles with draglines, preparatory to building an auto race track on the site. If the race track is built, employ- ees and spectators "would receive unnecessary radiation exposure," EPA said in a formal recommenda- tion made at the request of Utah Governor Calvin Rampton. Such exposure would come from radon gas emanating from the tail- ings, an exposure similar to that occurring in Grand Junction, Colo., and other places where the tailings, at first thought to be harmless, were used as construction fill material and as an aggregate for concrete. The EPA statement was pre- pared by the Radiation Programs Office in Washington and signed by William D. Rowe, deputy assistant administrator. It was based on the Agency's studies at the Vitro site in 1967 and 1968 as well as experi- ence with radioactive tailings in other locations. A special three-week survey at the Vitro tailings pile was made in May by a radiation team from NERC-Las Vegas, but the results were not available in time for Smith's meeting June 7 with a com- mittee appointed by Gov. Rampton to consider the problem. The monitoring team was headed by David L. Duncan, project officer, and included Gregory G. Eadie and Dwayne L. Rozell, of Las Vegas, and Jon Yeagley of the Denver Regional Office. They were as- sisted by Blaine Thomas and Jeff Throckmorton of the Utah State Division of Health. The EPA statement advised a "hands-off" policy on any use of uranium tailings until legal means have been set up to control such uses. It noted that Utah has no laws or regulations for tailings con- trol and that the Vitro site develop- ment was started "without the knowledge of the State's radiologi- cal health program." "Radon emanation from the tail- ings pile does not present a signifi- cant hazard to the surrounding community as long as there are no structures within one-half mile of the site," the statement said. But at the site itself "radon concentra- tions exceed the current limits for population exposure . . ." and would be a hazard to "any occupant of a structure built over or adjacent to the tailings." The Agency recommended that the tailings be graded and covered, to prevent them from "migrating" by wind or water erosion or by truck hauling, and fenced to keep people away. It also urged the State to establish control regulations and to consider possible remedial actions for four business buildings just west of the site. The monitoring team that sur- veyed the area last month took dosi- meter readings in the four buildings as well as air samples from three stations on the pile itself and one at a suburban sewage treatment plant. Smith said one possible use of the site might be for a sewage treatment plant, which needs a large area for ponds and filters, operates virtually unattended, and is not frequented by the public. Old Age Overtakes Big Sam, Steer With Hole in Stomach Big Sam, the steer with a hole in his stomach, died last month at the experimental ranch in Nevada where he had quietly helped EPA scientists throughout his nine-year life. Sam was one of a test herd of steers and cows that were period- ically allowed to graze on the Atomic Energy Commission's Nevada Test Site, an area sub- ject to radioactive fallout from nuclear experiments. Sam and several other animals in the herd had "fistulas," or sur- gically created holes, permitting EPA veterinarians to remove the contents of their rumens to check on what was happening to the radioactive isotopes in their feed while it was being digested. Big Sam was the most famous of the herd, for he had been sent to expositions and state fairs in Nevada, Texas, and New Mexico and had appeared on many tele- vision programs to illustrate en- vironmental radiation monitor- ing. Once the governor of Ne- vada shook his hoof for the press cameras. On such occasions Sam wore a small plexiglass window in his fistula, through which the churn- ing rumen contents could be seen. But usually he wore a sim- ple leather plug. None of the animals that have grazed on the atomic test site has suffered any ill effects trace- able to radiation fallout, but ob- servation of the herd and moni- toring of isotope levels in meat and milk is continuing. The test ranch is operated by EPA's Na- tional Environmental Research Center at Las Vegas. An autopsy showed that Big Sam died of natural causes. Nine years is an unusually long life. — 6 — ------- 48 ATTEND GPO COURSE ON PRINTING Forty-eight EPA employees from regional offices, research centers, and laboratories throughout the country attended a three-day semi- nar on "Editorial Planning for Printing Production" in Washing- ton last month. The lecture and workshop course was arranged by Henry Washing- ton of the Printing Management and Distribution Section and Paul Ceresini, General Services Branch. It was presented by the Govern- ment Printing Office experts under the leadership of Robert McKendry, to help upgrade the work of the Agency's printing control officers, editors, writers, and illustrators. Topics covered included format and type selection, copy prepara- tion and proofreading, graphic de- sign, printing methods, and printing procurement through GPO regional centers and commercial firms. Give-and-take panel discussions with GPO people tackled many of the printing production problems of individual Agency programs, and Mr. McKendry said he hoped that similar meetings could be held in the future. Attendees were given certificates for completing the course, and the sessions concluded with a tour of the main GPO publication facility. Nine Regional Offices, four re- search centers, two detached labo- ratories, and Agency headquarters were represented at the sessions. Inside EPA, published month- ly for all employees of the U.S. Environmental Protection Agen- cy, welcomes contributed articles, photos, and letters of general interest.

Jerry Moore's Work Helps Win State Award for Service Club Jerry Moore, a fish and wildlife reviewer in EPA's Office of Pesti- cide Programs in Washington, is credited with helping to win a statewide award for the Chantilly, Va., chapter of the Jaycees service club. The Outstanding Environmental Award was presented recently to the chapter for a series of voluntary projects during the last year, all sparked by Mr. Moore: • He planned and super- vised the landscaping of the State Jaycees' Camp Virginia for retarded children near Roanoke. • He designed and guided the development of two "nature trails" in Fairfax County park- land, for one of which he ob- tained a grant from the national Jaycees organization, with matching funds from the Depart- ment of Health, Education, and Welfare. • He obtained 400 plants and shrubs that had been planted for the Transpo '72 exhibition last summer at Dulles Airport (de- signed by Mr. Moore) and had them transplanted after the exhi- bition to the grounds of two schools in Fairfax County and to a local park, all at no cost to the county. • In cooperation with the Vir- ginia Department of Highways, a tree nursery, and the Chantilly Jaycees, he designed and directed the landscaping of an entrance to a new housing development, Greenbrier. Moore is also an instructor in wildlife management at Northern Virginia Community College, and is working with the college adminis- tration to increase the number of environmental courses available in the State's community college sys- tem. ------- Scholarship Deadline Is July 15; DANIEL SNYDER The deadline for applying for EPA scholarships for the 1973-74 academic year is July 15, accord- ing to Robert F. McDonald of the Office for Planning and Manage- ment, who manages the Scholarship Fund. The fund now has about $5,000 to distribute, McDonald said, mostly from honoraria and fees offered to Agency officials for speeches and magazine articles. EPA officials cannot accept such payments, but can ask the speech-sponsoring or- ganization or the magazine pub- lisher to make a voluntary chari- table contribution in lieu of the fee. The Fund was established two years ago to receive such contributions and last year awarded $5,550 in scholarships. The scholarships are awarded to children of career employees hav- ing at least three years of service (or children of deceased or disabled employees). Recipients must be full-time students at an accredited college or junior college. Sixteen persons held EPA Schol- arships during the academic year that ends this month, and only one of these is graduating, McDonald said. The scholarships are renew- able, but by June 1 only one or two renewal applications and 10 or 12 new applications had been received. Applications forms may be ob- tained from the Personnel Officer at Report Due Soon On Monitoring '72 Nuclear Testing The NERC at Las Vegas is pub- lishing this month a technical re- port on environmental radiation monitoring of all underground nu- clear tests made by the United States in 1972. The report describes the methods used and data obtained in "off- site" areas not immediately adja- cent to "ground zero" the well-head above the detonation location. any EPA location. One of the biggest sources of speech-fee contributions to the Fund was cut off suddenly at the end of April, when Administrator William Ruckelshaus left EPA to become acting director of the Fed- eral Bureau of Investigation. Ruck- elshaus had to cancel speaking en- gagements that would have added "about $3,500" to the Fund, Mc- Donald said. The Fund also welcomes dona- tions from EPA employees and others. But the income from such tax-free gifts has dropped consid- erably from what it was last year, he said. A five-man board of trustees will meet shortly after July 15 to choose the scholarship recipients. Daniel J. Snyder III was ap- pointed regional administrator of Region III, Philadelphia, last month. Snyder had been acting in that post since Edward W. Furia re- signed in February. Snyder joined EPA in January, 1972, as regional counsel and five months later was named acting deputy administrator for Region III. A native of Greensburg, Pa., Sny- der is 29 years old and a graduate of Dickinson College and the Uni- versity of Virginia Law School. He has been teaching environmental law at the Villanova University Law School, Villanova, Pa. He and his wife Lynda live in Philadelphia. Cywin Wins Patent on System For Disposing of Waste Heat A patent on the design of a "closed loop" system to dispose of waste heat from power plants by using a municipal water supply as a "heat sink" has been granted to Allen Cywin, chief of EPA's Efflu- ent Guidelines Division. Cywin conceived the idea about three years ago when he was direc- tor of Applied Science and Technol- ogy for the Federal Water Quality Administration, an EPA predeces- sor agency in the Department of the Interior. Cywin recently received notice that his patent had been allowed and numbered and would be issued in two or three months. As a Federal invention, the pa- tent "belongs" to the Interior De- partment but it is usable by any- one without payment of royalty. "All I get from it is some satisfac- tion," Cywin said, "and an item for my personnel record " Cywin's scheme offers several ad- vantages: prevention of thermal pollution of rivers or lakes, avoid- ance of costly cooling towers, and beneficial slight warming of the municipal water system. Water that has been heated by passing through the condensers of a power station or industrial plant, he explained, would go to the city water system's intake for treatment and distribution to domestic users. Much of the added heat would be absorbed by the ground in which the water mains are laid. Most city sys- tems have so great a volume of water flow that there would be only a few degrees rise in temperature at the tap. This warming would be desirable for the great majority of water uses, Cywin said, and it would speed bacterial action in the sewage treatment plant at the end of the line. Cywin also claims his scheme could be adapted to the reuse of treated effluent water from sewage plants for power plant cooling. In such cases, if the effluent water quality is unsuitable for direct use in the municipal system, a heat ex- changer or evaporator would be used to transfer the heat energy from effluent condenser water to the municipal system sink. ------- |
