   Interim   Ocean   Dumping    Rules   Set
  Interim regulations to control the
dumping of  wastes into  ocean waters
have been announced by EPA Admin-
istrator William Ruckelshaus and will
be published  soon in  the Federal
Register.
  The interim regulations provide for
the application and issuance of permits
prior to  promulgation of final regula-
tions by EPA and are required by the
Marine  Protection,  Research,   and
Sanctuaries Act of 1972 (Public Law
92-532).
  The Act  takes effect on April 23,
six months  after  its enactment.  In
anticipation  of this deadline the pro-
posed  interim regulations for the trans-
portation and dumping of materials in
the  oceans  must  be published at  an
early date to allow both the Regional
Offices and  potential dischargers suf-
ficient opportunity to apply for and
process applications for permits. After
April  23, all ocean disposal of waste
material without a permit is illegal.
  An estimated  1,000  permits are
expected to be issued by EPA regional
administrators in the seven  coastal
regions.

Two Exceptions
  The  EPA  permit authority  is for
transportation and  dumping  in  the
ocean of all material, with the excep-
tion of dredged spoil and fish wastes.
Dredged spoil permits are to be issued
by  the  Corps  of Engineers.  Corps
permits for dredged spoil must  meet
EPA's criteria for open water disposal
and must  be disposed  of  at  sites
designated by EPA.
  A permit is not required for dump-
ing  of fish wastes unless  these wastes
are  dumped  in  harbors  or enclosed
bays or any location where EPA finds
that  this  dumping could endanger
health,  the environment, or ecological
systems in a specific location.
  The  regulations will be  followed in
a short time  by  criteria under  which
   How to  Apply for  a  Permit
     Any  waste discharger  may ap-
   ply for  an interim ocean  dumping
   permit simply by  writing a letter
   to the regional EPA administrator
   in his region. This  letter must con-
   tain  at least six items of informa-
   tion:

     1.  Full identification of the ap-
   plicant,  his location, and the con-
   veyance  to be used to transport
   the waste to the ocean.
     2.  Full physical and  chemical
   description  of  the  material to  be
   dumped  and the quantities to  be
   dumped.
     3.  A  description of  the pro-
   posed dumping site.
   4. A description of the process
or  activity  which  produces  the
waste mat'>r;'il.
   5. Information of the  past ac-
tivities of the applicant or others
in disposing of such waste.
   6. A  description  of available
other means of disposal, with ex-
planations  of  why  such  other
means  are considered  inappro-
priate.
   The  regional  administrator,  at
his discretion,  may require addi-
tional information from the appli-
cant, and may visit the waste pro-
ducing facility to determine what
additional data are needed to com-
plete the application.
 ocean disposal permit applications will
 be evaluated for issuance or denial of a
 permit.  These  must  be  published
 before April  16, 1973, to nice I the
 legislative mandates of Sect inn 403  of
 the  Federal  Water Pollution  .Control
 Act  Amendments   of  1972  (P.L
 92-500).
   The regulations and  criteria will  ho
 used to operate the program,  and pub-
 lic comment will be solicited for neces-
 sary revisions before promulgation  of
 final regulations und criteria, expected
 in August.

 No Forms To Fill
   There arc no forms  to fill out for
 interim dumping  applications.  The
 applicant  must  tell  EPA  what  he
 wants to dump, where, how,  and how
 much, (see adjoining box for particu-
 lars).
   Within  10 days after receipt of a
 completed  application, the  regional
 administrator will  issue  an  interim
 decision, in  writing, to the applicant.
 If  this  tentative decision is  to granl
 the  permit, it must specify  the ap-
 proved dumping site, any special con-
 ditions  deemed  appropriate by EPA,
 and a time limit.
   All  interim permits will expire  90
- days after  the  permanent  dumping
 regulations arc adopted, if they have
 not  already expired.
   The permit program will be admin-
 istered jointly by EPA headquarters
 and regional offices. Headquarters will
 primarily   be  responsible   for  the
 development  of regulations  and  cri-
 teria for  the administration of the
 permits. Headquarters will also provide
 technical assistance  to  the regions  on
 particularly  difficult  problems, main-
 tain a  national inventory of  dumping
 activities,  and compile  the  reports
 required by  the  law.  Headquarters

NBS   Aids    Pollution   Measurement
      By Robert J. Griffin Jr.
   National Bureau of Standards

   As the  new  ambient  air quality
and  automotive  emission  standards
take  effect,  the  ability  to  measure
pollutant  levels  accurately  assumes
ever  increasing  importance.  Without
accurate and  reliable measurements,
enforcement  actions  will  be  difficult
or impossible to sustain in court; un-
less measurement values  obtained in
all parts of the  country are compar-
able  for given  pollutant   levels,  the
law cannot be administered fairly.
   To help provide industries, munic-
ipalities and  regulatory agencies with
the means  for  making  accurate air
quality measurements, EPA has con-
tracted with the  National Bureau of
Standards, Department of Commerce,
for development  of  Standard  Refer-
ence  Materials (SRMs) that can  be
used  to help assure accurate measure-
ments for a  number of common air
pollutants.

Three Requisites
   Paul Call, chief  of  the Office of
Standard  Reference  Materials,  NBS,
cites  three essential  prerequisites for
accurate air quality  measurements: I)
a rational system of base units (e.g.
those now  defined  by  the Interna-
tional  System  of Units,  commonly
called the  metric system);  2)  mater-
ials well-characterized with regard to
the properties of interest; and  3) ref-
erence  methods, based  in  part  on
SRMs,  of  proven and demonstrated
accuracy.
   SRMs consist  of  materials  whose
physical or  chemical properties  are
known and  that  can  be compared
with an unknown sample, or used to
calibrate  measurement  equipment.
For example, a  sulfur dioxide  (SO2)
permeation  tube, developed  by EPA,
has been evaluated  and  certified by
NBS  for the  calibration of  instru-
ments used  to measure the concentra-
tion of SOj in the atmosphere.
   This SRM-wliich comes  in three
different sizes to cover several  ranges
of SO2  concentration  consists of a
plastic tube, capped at each end, con-
taining liquid S02.  Gaseous  SO2  dif-
fuses  through the plastic tube at a
                       ' '"' *
                        •

 The sulfur dioxide  permeation tube is  calibrated by observing the rate of
 weight change over time, as S02 permeates through the tube. Here, a tube is
 being weighed on an analytical balance.
rate that  is constant at a given tem-
perature. Thus, when it is placed in a
stream  of air with known  flow and
volume characteristics,  and  with the
temperature  held constant,  a  known
concentration of SO2  is imparted to
the air stream. The air  stream  can
then be directed into the  SO2  mea-
surement  device to check its calibra-
tion.

Others on the Way
   Dr. James R. McNesby, director of
the NBS  Measures for Air Quality
Program,  said  SRMs are now being
developed  to  calibrate  equipment
used to measure the following:
   • Pollutants  in   ambient  air
     -nitrogen  dioxide, carbon di-
     oxide  in nitrogen; carbon mon-
     oxide  in nitrogen; ozone; and
     hydrocarbons (as propane).
   • Pollutants  in  automotive emis-
     sions—carbon  dioxide  in  nitro-
     gen;  propane  in  air;  carbon
     monoxide in nitrogen; and ni-
     tric oxide in nitrogen.
   • Pollutants in power plant and
     industrial  stack  gases—carbon
     monoxide; propane; nitric  ox-
     ide; and sulfur dioxide.
   As SRMs  for these pollutants be-
come  available,  and  as  reference
methods are  developed and validated,
the field test methods used by indus-
try and State and local  agencies  to
monitor pollution levels can be asses-
sed  to  determine  their  accuracies.
Eventually,  it  will  be   possible  to
maintain and assure the long-term in-
tegrity  of the measurement  system
through the use of SRMs in conjunc-
tion with accurate field methods.

Ghlorination:   Bad    Effects  Studied
   When treated waste water is chlou-
nated before discharge into a stream or
lake  to kill microorganisms that cause
disease or odors, does the chlorine also
injure or kill fish and other desirable
forms of life in the receiving waters7
   This question  may be resolved in a
multi-Faceted study now under  way
in EPA laboratories in Cincinnati and
Duluth  and  at  sewage  treatment
plants  in Wyoming  and Grandville,
Mich.,  two  small  cities near Grand
Rapids.
   The study is comparing  the effects
of various disinfection  methods  on
several species of fish and fresh-water
invertebrates, using waste water from
an activated sludge plant (Grandville)
and  a trickling  filter   plant (Wyo-
ming).

Four Different Streams
   The fish  and  other  organisms  are
kept in tanks under closely controlled
conditions.  Each  tank  receives  a
stream of waste  water  that has been
treated differently.  chJormation in
the usual way; chlorination followed
by dechlorination  by sulfur  dioxide,
disinfection  by  ozone;  and  an un-
treated control  stream. Comparable
work  with bromine  chloride  is also
being considered.
   Ozone has been used widely for dis-
infection of drinking water in Europe
but rarely in America.  Very little is
known about  the  use  of  ozone  for
disinfection of wastewater.

5616,000 Grant
   EPA is supporting the investigation
with a $616,000 grant, and the cities
of Wyoming  and  Grandville are con-
tributing  $32,000.  Overseeing   the
work are  Cecil W. Chambers, research
rmcrobiologist of EPA's  Advanced
Waste Treatment  Laboratory,  Cincin-
nati; Or. William Brungs, EPA National
Water  Quality  Laboratory,  Duluth,
Minn ; James A  Sheeran and Paul T.
Spelman,  civil  engineers,  Wyoming,
and   Dr.  Roland   Ward   and  M
DeGraeve, biologists, of Grand Valley
State College, Allendale, Mich.
   The bioassay work, involving long-
term effects on  fish reproduction as
well  as short-term  toxicity  tests, is
being performed by the college biol-
ogists, using the most  up-to-date pro-
cedures  provided by  EPA's Duluth
laboratory
   Chambers  said  the  researchers
hope to learn which system of treat-
ment  will provide  adequate disinfec-
tion  with the lowest toxic effect  on
the ecology  of the receiving waters.
   Both  the Wyoming and Grandville
treatment  plants  discharge  their  ef-
fluent into the Grand River, which
empties  into  Lake Michigan about 45
miles away.

Chlorine Compound Study
   Another environmental  aspect of
chlorination  is being  studied  at  the
Duluth branch of the  University of
Minnesota under an EPA grant
   Drs. Robert M  Carlson and Ron-
ald Caple,  principal investigators,  are
seeking to  isolate and  identify  the
compounds formed when chlorine is
added  to  waters containing certain
types of industrial chemical wastes
   They have  found that biphcnyl, a
common   industrial  substance,  cun
combine  with  excess  chlorine   in
water to form compounds similar to
polychlonnated biphcnyls, PCBs, that
persist  in the  environment.  PCBs  arc
fat-soluble,  and  are concentrated  in
the  food chain, with possible  long-
term effects that many biologists fear
may be as bad as those of DDT
Interim   Regulations   Are  Set
For   Ocean  Dumping  Permits
       (Continued from page 1)
would also grant "general permits" for
the dumping of  small quantities of
relatively  inert  wastes  at designated
sites.
   In keeping with the Agency's policy
of  decentralization,   the  regional
offices would receive applications for
permits  for  ocean  dumping  within
their regions. The regional administra-
tors  would process the application,
make  necessary administrative, scien-
tific,  and technical  determinations,
determine  the length of time for the
permit, and issue the permit. Regional
offices would also be required to main-
tain necessary liaison with other  Fed-
eral agencies  field operations involved
in ocean dumping within their region.
   If an operation affects two regions,
it is  anticipated  that  both regional
administrators would coordinate the
processing of the  permit applications.

Waste Dumping Inventory
   Information  obtained from  the
permit applications will provide  EPA
with  an   inventory  of  the  types,
amounts, and qualities of materials dis-
posed of at sea  Designated dump sites
will  be  monitored  periodically in
cooperation with the National Oceanic
and Atmospheric  Administration and
the Coast Guard. This momloimg will
provide informal ion on any dclci mo-
tion in the  quality of the cnvnoiimciil
at the sites  so thai adjustments may he
made in the dumping pioccdincs to
effect reduction in  these damages In
the  designation of pcnnancnl dump
sites, areas  with minimal  nalinal ic-
sourccs will be selected to mimmi/e
the risks of dumping.
Last  Escape Route
  Dumping in the ocean has been in-
creasing steadily,  and  Ruckclshaus
thinks it would increase  even  faster
without controls, m response  to stric-
ter  curbs on waste discharge  to the
air, fresh waters, and the land.
  Ocean dumping  is the  "last  major
escape route" to move wastes to an-
other location or  medium,  rather
than to  "undertake  a  responsible
effort to  treat  wastes and improve
technology  to minimize or eliminate
wastes," he said
  "The proposed regulations arc in-
tended  to  ensure  that  all  ocean
dumping shall be done at designated
sites, that  toxic materials be strictly
controlled,  and information obtained
(in the permit program) will be used
to further  abate and  prevent pollu-
tion of the oceans."

Research  Tackles   Chemical   Spills
    By Dr. Joseph P. Lafornara
    Edison, N.J., Water Quality
       Research Laboratory
   When you  mention  spill control,
most people think  of oil  spills,  be-
cause there  are so many  of them and
they have  such a  vast potential  for
environmental  damage.
   Other  hazardous   chemicals-
sulfuric  acid,   phenol,   acrylonitrile,
etc.—are spilled less frequently, but
they are also a problem.
   Until recently, the attitude to such
spills has been:  "There  is very little
that can be done, except to evacuate
the area and warn downstream com-
munities."  There has been no  ade-
quate  technology to contain, control,
and remove such spills.
   EPA's  Office of  Research  and
Monitoring has initiated  several inten-
sive research programs to try  to nar-
row these  gaps in  technology, work-
ing through the Edison Water Quality
Research Laboratory, a branch of the
National   Environmental  Research
Center in Cincinnati.
   Since many chemical spills occur
on  land and then  run  into a water-
course, it was  considered necessary to
seek methods  of containing the flow
to prevent the contamination of near-
by  streams or ground  water.  EPA
therefore awarded  research  contracts
to  three  corporations  to  investigate
various aspects  of  the  containment
problem.
   Fig. 1. Technician applies quick-setting foam plug to stop this benzene leak.
Fast-Acting Plugs
   It is apparent that the best way to
contain a spill  is to  stop flow from
the leaking  container. North Ameri-
can Rockwell Corp.'s Rocketdyne Di-
vision  is  working on  quick-setting,
foamed-in-place  plugs to stop  such
leaks. They have  demonstrated the
feasibility of these materials to  stop
leaks and ruptures in a  wide variety
of  containers  and  under  a broad
range of  circumstances, even under
water.
   Figure  1 shows a technician apply-

ing a foam plug to a leaking 55-gallon
container of  benzene. Rocketdyne is
in the process of perfecting an  appli-
cator for the  plug, and an operational
system  should  be available with  the
next few years.
Plastic Dams
  In cases where it  is not possible to
plug a leak, or where the material has
already  been  spilled  from a truck,
tank car, or in-plant  facility,  it  is de-
sirable to prevent the spill from flow-
ing into  a watercourse. MSA Research
Corp. has demonstrated the feasibility
of using foamed-in-place plastic darns
to stop the flow of spilled hazardous
materials.
  Figure 2 shows a  test storm drain
that has been dammed up  to prevent
a spill from reaching the storm  sewer
and its  receiving waters. Other  tests
have shown these dams to be  effec-
tive in  containing spills on open  ter-
rain. Once a  spill is confined, the ma-
terial can be vacuum-pumped into a
proper container for treatment or dis-
posal.
Gelling the Spill
  However, a contained spill can still
contaminate  ground  water  through
percolation through the soil. To pre-
vent this, CALSPAN Corp. has been
working on  methods  for  quickly
gelling   hazardous  liquids.  Using a
blend of commercially  available poly-

meric  materials,  CALSPAN  has suc-
cessfully gelled  a variety  of liquids,
both  water-soluble  and  water-insol-
uble. The polymers convert the  liquid
into a thick, jelly-like mass that will
not soak into the ground.
   Figure 3 shows a blended polymer
gel  being used to immobolize a  cyclo-
hexane  spill.  The  company  is now
working  on optimizing the gel formu-
lation  and developing  a  rapid dis-
penser for  it.
Treatment  Methods
   For spills that have  already con-
taminated  water bodies,  mobile treat-
ment  units are  being developed  for
EPA by  Rex Chainbelt,  Inc., and In-
dustrial  Bio-Test  Laboratories,  Inc.,
for  use on small watercourses  where
confinement of the  spill  to a small
area is possible.
   Rex  Chainbelt has designed, built,
and tested a trailer-mounted physical-
chemical treatment unit that can han-
dle  200 gallons per minute,  shown
in Figure 4. It consists of three large
columns  containing  activated carbon,
three  smaller  multimedia filters, and
several  tanks  for  sedimentation,
chemical reactions, and storage.
   Industrial  Bio-Test  has  demon-
strated on a smaller scale (10  to  15
gpm)  a  very  fast-acting system  for
physical  and  chemical  treatment.
After  pumps  suck  up  the  spilled
liquids,  they  are highly  pressurized
before they undergo the appropriate
processing: aeration, mixing  with pre-
cipitating  or  flocculating  agents,  re-
actant  chemicals, or combinations  of
these.  This  "dynamic   chemical   re-
actor"' has been successfully coupled
with  a magnetic  separator, and  the
company  plans to  scale it  up  to  a
250 gpm capacity.
Large-Scale Treatment
   In  cases where the spill cannot be
confined  to  a small  area,  in-placc
treatment   is  necessary.  Battcllc
Memorial   Institute's  Pacific  North-

west  Laboratories,  under  LPA  spon-
sorship, has demonstrated I lie use of
lion table mass-transfer media (carbon,
ion exchange  resins,  etc.) to remove
soluble  ha/ardous  materials  from  a
contaminated  lagoon.  The media are
introduced  to  the   bottom  of  the
watcrbody  in  weighted  containers
which  can be  dropped  from  a heli-
copter or other aircraft,  as shown in
Figure 5.
   The media arc then slowly released
from  the  containers  upward  through
the water column, where they decon-
taminate the pollutant while bringing
it  to  the  water surface  where  it can
be gathered and  removed  by conven-
tional oil-skimming devices.
   These methods and devices are but
a few  examples of EPA's current  re-
search  efforts  to contain  and  treat
hazardous  chemical  spills. All arc in
the experimental stages;  none can yel
be regarded as fully proved and oper-
ational.
   Other,  related projects under w;iy
include: activated carbon  "lea  bags''
for in-strcam  treatment; field  detec-
tion  kits;  fixed-station  spill  alarm
systems; in-strcam systems lor  accel-
erating biological treatment; "se;i cur-
tain"  booms,  like those  used  for  oil
spills, to  confine hax.ardous  materials
in  a watcrbody; and  specific methods
and  instructions  for   disposing  of
spilled or  unused pesticides.
   With  these  new   tools and   tech-
niques,  we expect that industries and
government agencies will soon be in a
more  favorable position  to cope with
chemical spill problems.

Lake   Ontario   Survey  Nearly   Ended
   A year-long survey of Lake Ontario
is  winding  up  this month on  the
Canadian  research  vessel  Limnos,
undeterred by  the low temperatures
and high winds of a record winter.
   The Limnos cruises are part of the
International Field Year for the Great
Lakes (IFGYL), a joint project of the
U. S.  and Canada  involving dozens of
official agencies in both nations and
more  than  600 scientists  and tech-
nicians.
   Scientists  working  on the project
pronounce the acronym "Eye-feagle,"
and  call  it  the  "endangered  inter-
national bird."
   Object of IFGYL  is  to provide
sound scientific  data for halting pol-
lution  in the Great Lakes and man-
aging  their vast  water  resources. The
five lakes together contain more than
5,000 cubic miles  of water, or  about
20 percent of all the liquid fresh water
in the world.
   Lake Ontario and its 30,000-square-
-mile  drainage  basin was  chosen  last
year for intensive  study. Throughout
last summer  and fall, the  survey ship
Researcher,  one of a  fleet of vessels
belonging to the National Oceanic and
Atmospheric  Administration  of  the
Department of Commerce, cruised the
lake to gather data on  its waters, cur-
rents, and biology. When winter came,
the Limnos, based  at Burlington, Ont.,
took over.
Canadian research vessel Limnos is cruising on Lake Ontario to gather scientific
information for International Field Year for the Great Lakes.
Technicians prepare to lower sampling
package into Lake Ontario's waters.
   In addition to the  cruising vessels,
aircraft, weather stations, a network of
towers  and buoys,  and even satellite
instruments are  involved  in the data
gathering program
   Nearly  equal resources are being
used for IFGYL from both sides of the
border.  The  Canadian  program  is
directed  by the Center  for Inland
Waters  at Burlington, and the U. S.
program,  led by NOAA, includes per-
sonnel from EPA, the National Science
Foundation, and the Departments of
Interior, Transportation, and Defense.
   EPA's Grosse He, Mich., laboratory,
headed  by Dr. Tudor Davies, has been
active in planning the sampling activi-
ties and experiments undertaken  the
the cruise ships. Al Baldwin of EPA's
Region  II laboratory at Rochester has
represented  the   Agency   on  the
Limnos's winter cruises. Students from
the  University  of Michigan,  Ann
Arbor,  and the State University  of
New York, Albany,  have been working
as technicians on the vessel.
   The   data   collection   phase   of
IFGYL is scheduled to end this spring.
Data  reduction  and  analysis  are
expected  to take another year, and the
publication of final reports and recom-
mendations will begin in 1974.
   Two  data banks are being  estab-
lished, one for each country, but with
joint access to each by scientists of the
other country.
   The  IFGYL  scientists  hope  to
describe, more accurately and  com-
pletely than ever before, the condition
of Lake  Ontario, what goes into  it,
what happens in  it, and what  comes
out.  They plan  to create  computer
models of the changes taking place in
the lake waters from season to season
and  year  to year, models that will
permit  reliable predictions of how the
lake  will  respond to  environmental
changes in the Ontario basin.
   One  benefit  of  the  study  is
expected to be better management of
the lake's water  level, which affects
hydroelectric power generation, navi-
gation, and shore erosion.

   The EPA  Bulletin  is published
   monthly by the Office of Public
   Affairs to inform State and local
   environmental  officials of EPA's
   research,  standard-setting,  and
   enforcement work.

Spur  to  EPA   Enforcement:
People   Want  to   Do   Right
   Enforcement of environmental reg-
ulations  is  becoming  easier  because
"most people want to do the right
thing,"  according  to Arthur  W.
Busch, EPA Region VI administrator
at Dallas.
   Polluting industries  are  finding
that  "if they will meet us halfway,
we're not  going to  take them to
court," Busch said recently in a state-
ment issued at  the end of his first
year  with the Agency.
   The  former professor of environ-
mental engineering at Rice University
credited  strong  public  support  for
pollution  control  with helping to
"create a climate" that often makes
lawsuits unnecessary.
   Another  factor  in this  "climate,"
he said is technical expertise. EPA's
technical specialists have won the re-
spect of both sides-polluting indus-
tries  and  environmentalists—with  the
result that  their knowledge  carries
weight  with jurists and  the  public
too.
   "When we  have to take a case to
court, we prepare the very  best infor-
mation  available so  that a court  can
rule  properly  on the  allegations we
make," said Busch.
   He cited two  recent court cases re-
flecting improved relations and under-
standing between EPA and  companies
which have pollution problems.
   In an injunction action brought by
EPA  under  the  1899 Refuse  Act,
Federal District Judge John V. Single-
ton ruled in January that  the Rohm
and Haas  Co.  must limit its discharge
of certain  pollutants into  the  Hous-
ton Ship Channel.
   Judge  Singleton's  decision  cited
the company's  own  "extensive  re-
search and investigations.. . to reduce
its discharge  of harmful  effluents.
However,  during the course  of this
trial,  experts  representing  both  the
Government  (EPA)  and Rohm and
Haas  gave testimony in detail relating
to  measurement standards in  an at-
tempt to  aid  this court in construc-
ting  a  workable timetable  and to
establish such standards."
   The  judge's  order  requires  the
company  to reduce its ammonia dis-
charge  from  an estimated  10,000
pounds per day  to 7,500 Ibs./day by
April 1, and to 400 Ibs /day by the
end of 1974.  Chemical oxygen de-
mand of the company's effluent, now
estimated at 25,000 Ibs./day, must be
cut to  6,400 Ibs./day by July 1  and
to no  more  than  2,700 Ibs./day at
the end of next year.
   In another case  cited  by Busch,
the Houston Lighting and Power Co.
agreed   to  forego  construction  of
three  new  generating units at  its
Cedar  Bayou plant  to protect  the
ecology of  Trinity  Bay. The agree-
ment was part  of a  consent judge-
ment settling a  suit filed by  the De-
partment of Justice last March.
   "Legal action is  sometimes  the
best way, if not the only way, to re-
solve complex cases involving air and
water pollution," said Busch.  "Where
we have to bring a lawsuit, it is grati-
fying to see an increasing atmosphere
of cooperation on the part of all con-
cerned."
GOVT.  -  INDUSTRY

CONFERENCE  SET

ON  OIL  SPILLS
   A Government-industry conference
on  the prevention and control of oil
spills will be held on March 13-15 at
the Sheraton-Park Hotel in Washing-
ton, D.C.
   The three-day session  is sponsored
jointly by EPA, the U S. Coast Guard,
and the American Petroleum Institute,
trade organization of the oil industry
   The technical  sessions will review
the best current practices m preventing
spills  at exploratory and  producing
wells, refineries, pipelines, and termi-
nals and the best current  methods of
cleaning up spills after  they occur.
Other sessions will deal with the "fate
and effects" of spilled oil,  including
the identification of spill sources and
the impact of spills on land and water
ecologies
   The heads of the sponsoring agen-
cies  are scheduled  to address three
general  luncheon  sessions.
Officials  and  Public  Invited
To   Help  Set  Noise  Limits
   State and local environmental offi-
cials  and all interested citizens have
been  invited to help EPA develop regu-
lations  to limit noise from interstate
motor carriers and railroads.
   Noise standards for these carriers
must  be  formally proposed by the
Agency  before July  27,  under the
Noise Control Act of 1972
   Public comments are being sought
this month on methods of identifying
and measuring such noise and on sug-
gested techniques to reduce it
   Under the Noise Control Act, EPA
must propose noise standards for both
types of interstate carriers. In the case
of railroads, the  standards must limit
noise from the operation of rail yards
and  terminal  equipment;  for  motor
carriers the standards need  only limit
operational noise
   The  proposed standards  will apply
to both new and  old equipment, and
they  must reflect the degree of noise
reduction that can be achieved with
the "best available technology, taking
into account the cost of compliance,"
according to the Act.
   EPA is especially interested in pub-
lic suggestions on

   • Industry  and government regula-
     tions and standards that might
     affect, or be affected by,  noise
     regulation.
   • Demonstrable noise abatement
     and control techniques, and their
     effectiveness
   • Major  sources of interstate rail
     and motor carrier noise and data
     on the levels of noise they pro-
     duce.
   • Cost data  on  abatement  and
     control methods
   Persons wishing to submit informa-
tion  during the  rule-making  process
should send two copies of their  writ-
ten comments  to the  Office of Noise
Abatement and Control, EPA, Wash-
ington, D.C , 20460, by April 2.

Hearings  On  Gas   Rationing
   Nine  public hearings will  be  held
this month in Los Angeles and near-
by cities on EPA  proposals to reduce
air pollution there by gasoline ration-
ing and other restrictions on motor
vehicles.
   The hearings are expected to at-
tract  record  crowds  because  of  the
drastic and controversial  nature of
the proposals.
   Likely to be discussed  the most is
the plan to ration gasoline in the  Los
Angeles  area  during the smog season
from  May to October to cut gasoline
usage  as much as 82 percent.
   This is  the only way now conceiv
able for the area  to achieve  ambient
air  that meets the national standard
for photochemical oxidants by  the
1977  deadline set by the Clean  Air
Act, according to  EPA  Administrator
William Ruckelshaus.
   Other  control  measures  proposed
by Ruckelshaus  Jan.  IS  included
strict  annual inspections for all motor
vehicles'  exhaust  emissions,  manda-
tory installation of control devices on
old vehicles,  conversion of fleet  cars
and  trucks  to  natural  gas or other
low-polluting fuel,  and  additional
controls on gasoline stations and  dry
cleaning establishments.
   The first hearing was held at Parker
Center Auditorium  in Los  Angeles
March  5  Other places and times are
Riverside, March 8, Long Beach, March
10, Van  Nuys, March 12, Pomona,
March  13; San Bernardino, March 15,
and Santa Barbara, March 19.

   The hearings will be conducted by
EPA officials from Washington, vith
Alan G. Kirk, deputy general counsel,
presiding.  Representatives of  the Air
Programs  Office  and  the Office of
Research   and  Monitoring  will  be
panelists  at each session.  Deputy Ad-
ministrator Robert W. Fn will attend
the first hearing.
   Persons interested  in testifying or
submitting statements should contact
EPA's Region IX office in San  Fran-
cisco,  submitting  four copies of pro-
posed  remarks  seven days before the
hearing date.

   The detailed  proposals are  avail-
able  for  public  inspection  at  most
public libraries  in  the Los  Angeles
area.  Records will  be kept  of each
hearing,  including stenographic tran-
scripts of questions and answers, and
these  records will also be made avail-
able to the public.
Lab Safety Note:

ORGANIC   SOLVENTS

CAN   BE  DEADLY!
   Most  State and  local  environ-
mental laboratories routinely use or-
ganic  solvents  that are highly flam-
mable, even explosive.
   Stringent  standards  for  the  han-
dling of these liquids are imposed by
the Occupational  Safety and  Health
Act of  1970,  according to Trenton
Crow, chief of EPA's Safety Manage-
ment  Branch.
   In  brief, the standards require that
flammable  solvents  be kept  in and
poured from vented safety  cans and
that  the  cans  be stored in properly
designed cabinets.
   Handling of solvents in glass bot-
tles imposes a severe fire  hazard  to
laboratory workers and should be dis-
couraged, Crow said.
   Glass-lined  safety  cans  with
spring-closing lids and spout covers-
which open to relieve internal  pres-
sure   in  the event of exposure  to
heat—are now  commercially available.
   Detailed standards under the Fed-
eral  law  are  listed  in the Federal
Register for Oct.  18,  1972, vol. 32,
no. 202, part II, on page 22170 (for
safety  can  design)  and  pages
22177-80  (for storage requirements).
