THE SITE-i i

2.1 Location of the Plant i

l 1

The C-E Hematite site is located in Jefferson County, j

1 Missouri, approximately 35 miles. south of the city i

of St. Louis. The location of Jefferson County within the State of Missouri is shown in Figure 2-1.

The site consists of 5 adjacent tracts totaling about-152 acres.

Figure 2-2 shows the location of the site within Jefferson County and transportation access to major i

highways. Jefferson County'is predominantly rural l

and is characterized by rolling hills with many sizeable Woodland tracts. An expanded section of the region within 5 miles of the site is shown in Figure 2-3.

I Small towns and settlements within 5 miles of the plant site are identified.

i I.

Figure 2-4 shows an elevated view of the C-E Hematite site. Figure 2-5 shows the boundaries of the site with

[

respect to the town area of Hematite, an unincorporated settlement about three-quarters of a mile southwest of i

the plant.

Begional Demography l-Jefferson County is sparsely populated with 50% of the land area classified as forest, 39% as productive farming such as' grain and hay, and approximately 11% as urban,

{

suburban, commercial and unused or undeveloped.

For the total of Jefferson County, the 1970 population density is 158 people per square mile. There are approximately 60 manufacturing establishments in Jefferson County.

2.4.

Meteorology General meteoroTogical characteristics of the Hematite site are similar to-those of St. Louis,' the nearest U.S. Weather Bureau recording station.

St. Louis is located at the confluence of two major rivers and near the geographical center of the United States.

~

To the south is the warm, moist-air of the Gulf of Mexico, and to the north in Canada'is a region of cold air masses. The alternate invasion of the St. Louis area by air masses from these sources,'and the conflict along frontal zones where they come together, produce a variety of weather conditions.

Winters are brisk, but seldom severe.

Snowfall has averaged less than 20 inches per Winter season since 1930. 'M_aximum temperatures are as cold as 32 or lower less than 20 to 25 days in most years. Summers i

are warm with maximum temperature-of 90* or higher an s

average of 35 to 40 days per year..The normal average-annual precipitation is about 36 inches. The three

-*~

Winter months are the driest, the Spring months are wettest and there are extended' periods without appreciable rainfall from the middle of the Summer into the Fall.

2.5 Geoloqy The 240-260 million year old Mississippian rock system of the:far' northeastern portion of Jefferson' County gradually changes to the 440-470 million year old Cambian system of the southwestern portion of the e.<

s-f Festus-Crystal City, Missouri, is. the nearest town

.j of any size, being 3.5 miles east of the site and having 'a population of 10,699. people, based on the 1970 U.S. census'. As~shown in Figure'2-3, the eleven

- towns and unincorporated settlements of Hematite, Deerfield, Victo'ria, Mapaville, DeSoto, Hillsboro, Olympia Village, Horine, Festus, Crystal City and Lake Wauwanoka are wholly or partly within 5 miles of the C-E site. Hematite is the nearest town to

~

the site, and has a population"of about -225 people.

Population, distance and direction of the towns from the C-E plant site are given in Table 2-1.

Other residential development has primarily been single-1 I'

family homes located intermittently along the area roads.

the fenced area located on the center site tract.

The fenced. area, parking lot and barns occupy about 5 acres. The remainder of the 16 acre center tract

[q l

is a grassy area which is kept mcwed, as is the two acre West tract. The North, East and South tracts, totaling 134 acres, remain undisturbed. Thus only about 3% of the site' is being_ utilized, while the-m

' County..The southwestern corner of Jefferson County is primarily dolomite '(magnesium limestone), with sandstone and chert (angular fragments of quartz) present in various quantities. A massive sandstone ridge runs across the County and is used for glass manufacturing and building purposes.

Some deposits of marble are also present in the County.

The site topsoil of the northern tract, beginning at the ridge 3ust northward of Highway 21A, is Tilsit Silt Loam. The fenced manufacturing area is situated on the fertile alluvial Union Silt Loam of the Joachim Creek bottomland.

2.6 Comoany Plans for Future Site Modifications _

No modifications are presently planned for alteration

- of the present C-E site boundary shown in Figure 2-5.

fj,,

Any expansion presently under consideration would take i

,o "

place within the fenced manufacturing area on.the g,[

{

central site tract.

1

\\,W Plans presently under study are the addition of scrap recovery and purificatior capacity in 1976, and increase of pellet production capacity in 1978. These proposed increases in capacity would be accomplished by using space now available in existing plant structures.

A plan is also being evaluated for expansion of uranium oxide production capacity in 1978. This plan involves an addition to an existing building to house the new equipment.

The abbve prooosed expansions would provide the capacity I

ProcessWater(continueo)-

Other water is lost as steam used to maintain process temperatures'or in heat tracing of process lines, Steam condensate is collected and discharged to the industrial waste system, or returned as boiler feed water.

1 Water is.also used in a wet scrubber system and for washing and processing UF6 cylinder heels. This water is tested prior to discharge to evaporation ponds-located within-the fenced plant area.

' 3.2.2 Eouipment Cooling Water Water is used'in the normal operation of the facility for cooling equipment. This is the. largest category of water usage on the C-E Hematite site. Equipment

. cooling ' water is essentially unchanged in both physical and chemical quality before it.is discharged to the' industrial waste system.- Some cooling systems are recirculatory, with only evaporative losses.

s 3.2.3 Water for Sanitary Pur,qases Later is used to service wash sinks, toilets and showers in Building Nos. 210, 240'and 255. Sanitary waste water is collected and discharged directly to the sanitary sewer system.

3.3 Disposal.of Discharged Effluents Table 3-1 indicates the type and volume of waste water effluents generated under normal conditions. Disposal of each type of discharged effluent is handled in the following manner.

I 3-2 l

q l

.f f

l 3.3.1' Sanitarv Waste' Water' Effluent-j a

Sanitary wastes from Building.Nos. 110, 240 and 255 flow into. sanitary waste.. lines which are routed to the sit'e septic' tank. The originating po'ints of the effluents are shown in Figure 3-2 along with -

1 the path that the wastes follow to the septic tank.

Most solids settle in the primary septic tank chamber-

'and are digested by bacterial action. The primary

. septic tank chamber overflows into a dosing chamber and a float-controlled pump discharges the overflow to a sand trickling filter. The' sand filter removes:

t most of the remaining suspended solids and-also reduces s

- the BOD (Biochemical Oxygen Demand)-of the effluent stream.

After passing through the sand filter,.the effluent is routed to the' site creek which discharges into Joachim Creek at the southern site boundary.

3.3.2 Industrial Waste Water Effluent s

Industrial waste water is discharged directly to the-site pond via the industrial and storm drain lines.

This waste water is mostly unchanged in both physical and chemical quality and receives no treatment. The industrial effluent contains no solid wastes. The originating points, including storm drains, of industrial waste water are shown in Figure 3-1 along I

with the. route followed by the drain lines to the site pond.

3.3.3 Radiological Waste Water Effluent Ra'diological liquid wastes:which contain uranium are ' generated in Building Nos. 240 and 255 as floor mop water and cleanup water. This water is evaporated in a special hbod to recover the uranium.

Radiological liquid wastes from the wet scrubber system and UF6 cylinder heel washing and. processing j

operations in Building 240 are discharged to evaporation ponds. located within the fenced plant area. This waste water is tested prior to discharge to determine that uranium concentrations are below acceptable levels..

Other radiological wastes, containing only small quantities.of uranium are generated by the laundry, cleaning of glassware in the laboratory, and.the sinks and showers in the change room. The laundry and.

laboratory effluents are discharged to the industrial waste system and the change room liquid wastes are routed to the sanitary waste system.
