This
manual is intended to provide guidance to federal and state
NPDES permit and pretreatment staffs in determining appropriate
limitations for the discharge of selected toxic pollutants in
the wastewater from industrial facilities where applicable Effluent
Guidelines regulations are not available. From
his extensive knowledge and comprehensive review of the treatment
technology available to industry, the author has determined,
in his best professional judgement, the final effluent concentrations
that can be achieved using his estimate of best available technology
(BAT) for the following toxic pollutants: arsenic, barium, cadmium,
hexavalent chromium, total chromium, copper, cyanide, fluoride,
iron, mercury, nickel, silver, and zinc. It is concluded that,
aside from a few extraordinary situations involving unusual
chemical interferences, the treatability levels provided in
the manual should be applicable, independent of industrial category.

Site is provided. The monitoring programs are designed
to collect data on the physical, biological and human environments
of the development area. Primary research during 1980 emphasized
completing baseline studies on terrestrial fauna, establishing
an air quality monitoring network, investigating potential
sources of fluoride in the Raft River Valley, and studying
water level changes in the shallow monitor wells in response
to development of the geothermal resource. (ERA citation 06:028520) |

During
the past year we continued our research on environmental control
technologies as they relate to coal preparation wastes and extended
our assessments to include studies of high-sulfur Appalachian
coal cleaning wastes. The most promising control technology
for dealing with high-sulfur coal wastes consists of sequential
slurry coating of the waste with lime and limestone. Codisposal
of coal wastes and alkaline soils or mine overburdens is partly
effective in controlling the leachate quality under steady-state
conditions. Comparisons between trace element concentrations
predicted by chemical equilibrium models and those obtained
in experiments with coal waste leachates yielded good agreements
for the major cations (Al, Ca, Fe) but,
except for fluoride, the major anions were not well accounted
for. The observed trace element concentrations were all
significantly lower than predicted. Calcination experiments
have shown that high-sulfur coal waste from Appalachia (Plant

The rational
development of processing technologies for the chemical treatment
of uranium mill tailings requires knowledge about both the chemical
composition and the mineralogical constitution of the tailings.
Knowledge of the tailings composition is also required to evaluate
the hazard posed by disposal of either treated or untreated
tailings. The potential hazards include
not only radiological hazards such as radon and its precursors
Ra-226 and Th-230, but also nonradiological hazards such as
molybdenum, other heavy metals, and non-metals such as fluoride,
nitrate, and sulfate. As a part of the Los Alamos effort in
support of UMTRA, a program of chemical and mineralogical analysis
of thirty-six mill tailings samples collected at three of the
priority sites (Durango, Salt Lake City, and Shiprock) has been
undertaken. In addition, data has been obtained on the water
leachability of the tailings samples collected at these sites.

uniformity within the particular cultivar, plant habitus, e.g.,
structural characteristics that make it suitable for this particular
application, and the potential for high ethylene production
when exposed to mild stress. Of the varieties grown in the growth
chambers, pink kidney beans and cucumbers were selected as most
suitable. Seven compounds were tested
by the procedure devised: two organic herbicides: Paraquat

The
phytotoxicity of gaseous hydrogen fluoride (HF)

The HF fumigation chamber and generating system was made operational,
safe, and reliable. Plants exposed to 20-minute doses of HF
gas developed typical foliar wilt, glazing, and necrosis dependent
on gas concentration, plant species, and environment. Pictorial
keys were constructed to aid in consistent grading of injured
plants. Visible foliar response of six species to HF gas was
comparable to their response to HC1 gas, but at smaller concentrations.
Seed development was inhibited after exposure to HF under certain
conditions. Literature concerning the effects of hydrocarbon
fuels on plants was reviewed. Plants exposed to sprays and vapors
of JP4 jet fuel developed water-soaked lesions and foliar necrosis
depending on amount of fuel applied. The response of seeds to

This literary
study deals with emissions from municipal incinerators and their
environmental effects. Because of the similarity of conditions
in Scandinavian countries and Finland, Scandinavian investigation
results are the main concern of this report. The studies indicate
that most hazardous from the environmental point of view are
the particles emitted in the air especially the heavy metals
cadmium, copper, chromium, lead, nickel and zinc. In the neighborhood
of most incinerators their quantities increased both in the
air and in the ground. Also the gaseous emissions from the incinerators,
most of all hydrogen chloride, hydrogen
fluoride, gaseous mercury and organic microimpurities
like PCB and PAH may cause environmental hazards. The quantities
of hazardous substances released with process water and slag
are relatively small, but the leaching
of heavy metals and fluorides from fly ash may cause environmental
hazards. The gaseous and particulate emissions varied

The
Raft River Irrigation Experiment investigated the suitability

selected field-grown crops.
Crop and soil behavior on plots sprinkled or surface irrigated
with geothermal water was compared to crop and soil behavior
on plots receiving water from shallow irrigation wells and the
Raft River. In addition, selected crops were produced, using
both geothermal irrigation water and special management techniques.
Crops irrigated with geothermal water exhibited growth rates,
yields, and nutritional values similar to comparison crops.
Cereal grains and surface-irrigated forage crops did not exhibit
elevated fluoride levels or accumulations of heavy metals. However,
forage crops sprinkled with geothermal
water did accumulate fluorides, and leaching experiments
indicate that new soils receiving geothermal water may experience
increased salinity, exchangeable sodium, and decreased permeability.

exposure. In rats sacrificed 6 hrs after whole body exposure,
dose-dependent increases in lung, plasma, and kidney total and
ionic fluoride concentration occurred. Rats excreted more fluoride
in the urine after whole body exposure than could be explained
by the amount of HF inhaled. Considerable evidence suggests
that airborne HF deposits on fur and is then ingested due to
preening activity. Urinary fluoride excretion was increased
by nose-only exposure. The urinary fluoride
excretion accounted for approximately twice the fluoride estimated
to be inhaled during exposure. Tissue fluoride concentrations
were elevated immediately after nose-only exposure. Fluoride

ingestion of water containing more than 8 ppM fluoride causes
fluorosis in humans. Fluoride salts are lethal to humans when

ranged from 0.1 to 1.3 milligram per cubic meter (mg/cu m) compared
with the recommended threshold limit value (TLV) of 5.0 mg/cu
m recommended by the American Conference of Government Industrial
Hygienists (ACGIH). Manganese ranged from less than detectable
to 0.05 mg/cu m compared with the ACGIH permissible exposure
limit of 5.0 mg/cu m. Aluminum ranged from less than detectable
to 0.04 mg/cu m, well below the ACGIH permissible exposure limit
of 5.0 mg/cu m. Copper ranged from less than detectable to 0.

Possible
adverse health effects caused by welding in coal washboxes at
the Peabody Coal Company (SIC-1211) near Beaver Dam, Kentucky,
were evaluated. The request was made by the United Mine Workers
of America following an incident involving a worker suffering
a stroke after welding in a coal washbox. The industrial hygiene
survey was conducted on January 24, 1982. A total of eight welders
were potentially exposed in the coal washboxes. Exposure to
total welding fume, iron-oxide (1309371) fume, manganese (7439965)
fume, fluorides, ozone (10028156),
carbon-monoxide (630080), and nitrogen-dioxide (10102440) were
monitored. The American Conference of Governmental Industrial
Hygienists (ACGIH) exposure limits for these substances are
5 milligrams per cubic meter (mg/m3), 5mg/m3, 1mg/m3, 2.5mg/m3,
0.1 parts per million (ppm), 50ppm, and 3ppm, respectively.
All exposures were less than the ACGIH limits or the NIOSH recommended
health standard. The authors conclude that the work practices

Environmental
and medical surveys and technological assessments were conducted
on July 18 to 20, 1978, and April 3 to 5 and June 11 to 14,
1979, to update environmental conditions and evaluate the ventilation
systems in the potrooms at the Kaiser Aluminum and Chemical
Corporation facility in Ravenswood, West Virginia (SIC-3341).
The evaluation was requested by a union safety and health committee
member of the United Steelworkers of America, Local 5668, on
behalf of the potroom employees. Personal and area air samples
were obtained for determinations of coal tar pitch volatiles
(56996932) (CTPV), polynuclear aromatic hydrocarbons (PNA),
total particulates, and fluorides,
indicator tube sampling was done for sulfur dioxide (7446095),
carbon monoxide (630080), and hydrogen
fluoride (7664-39-3). CTPV concentrations ranged from
undetectable to 0.37 milligrams per cubic meter (mg/cu m), exceeding
the OSHA standard of 0.20mg/cu m; PNAs were present in 27 of
46 samples; total particulates ranged from 0.3 [abstract truncated] |

Personal
and area air samples were collected, workers were given a medical
questionnaire and ventilation was assessed at Kaiser Aluminum
and Chemical Corporation (SIC-5051) in Ravenswood, West Virginia,
from July 18 to 20, 1978 and April 3 to 5 and June 11 to 14,
1979. The evaluation was requested by a union safety and health
committeeman of United Steelworkers of America, Local 5668,
on behalf of an unspecified number of workers. Concentrations
of coal tar pitch volatiles (CTPVs) ranged from nondetectable
to 0.14 milligrams per cubic meter (mg/cu m) in April 1979.
Concentrations of benzo(a)pyrene (50328), chrysene (218019),
pyrene (129000), benzo(a)anthracene (56553), and fluoranthene
(206440) ranged from nondetectable to 3.80, 4.90, 32.90, 28.0
and 48.0 micrograms/cu m, respectively. Total
particulates and fluorides
ranged from 0.3 to 177 and 0.07
to 2.47mg/cu m, respectively.
Concentrations
of sulfur-dioxide and carbon-monoxide ranged from undetectable
to over 25 and 15 parts per million (ppm [abstract truncated] |

Personal
air samples were analyzed for nickel (7440020), tantalum (7440257),
ozone (100028156), cadmium (7440439), and fluorides
and a general work area environmental air sample was analyzed
for 1,1,2-trichloro-1,2,2-trifluoroethane (76131) and relative
humidity was measured at Fisher and Porter Company, (SIC-3824),
Warminster, Pennsylvania, on April 15 and 21, 1980. The evaluation
was requested by the management on behalf of rotometer assembly
employees who complained of headaches, nose bleeding and watering
of the eyes. Concentrations of
ozone, nickel, tantalum, fluoride
and cadmium were below the lower limit
of detection. The concentration of 1,1,2-trichloro-1,2,2-trifluoroethane
was 5.4 milligrams per cubic meter (mg/cu m), well below the
permissible criteria of 7600 mg/cu m. On April 21, 1980, the
relative humidity ranged from 21 to 30 percent and complaints
were received of dryness and burning of the eyes and dryness
of the throat. On April 15, the humidity ranged from 28 to 33
