#71—153

Environmental Protection Agency

ORDER

The Variance

is hereby granted until January 1, 1972, subject to

the following conditions:

1. Unloading of materials now in lagoon #2 that were held over from

• 1970 may begin at once provided adequate dilution is achieved.

A dilution ratio of 20:1 s1~allbe deemed adequate for an effluent

of BOD 100 ‘mg/l. The dilution ratio may be decreased by a factor

equal to any reduction in effluent BOD, Thus, a dilution ratio

of 10:1 is deemed adequate for an effluent of BOD 50 mg/l.

2. Low-flow augmentation is to be explored and utilized if possible

whereby non—process water from the city of Morton water supply,

water from excess capacity for food processing, or water from a

new well is added to the effluent from lagoon #2 in order to

increase the rate at which the lagoon may be unloaded according

to condition No. 1 of the order. Petitioner shall report to

the Environmental Protection Agency the feasibility of these

alternatives by October 1, 1971.

3. To the extent possible, material that is transferred from

lagoon #1 via the spray irrigation system shall be applied

to the watershed above lagoon #3 and restricted from the water-

shed of lagoon #2,

4. Libby, McNeill and Libby shall immediately further explore and

report to the Agency by October 1, 1971, the feasibility, including

working overtime, of building additional storage capacity (in

the form of lagoon #4 or by other means) in order to reduce the

amount of discharge below the 40.3 million gallons requested.

5. Petitioner shall proceed to install the clarifier as scheduled

with completion no later than January 1, 1972. If overtime work

would accelerate installation and significantly reduce the amount

of effluent that exceeds SWB-l4 standards for BOD and suspended

solids, Petitioner is directed to work overtime.

6. By January 1, 1972, Libby, McNeill and Libby is to be in full

compliance with the Rules and Regulations

of

SWB-14 which limit

effluent discharges to 4 mg/l BOD and 5 mg/l suspended solids.

7, Libby, McNeill and Libby shall post with the

Environmental

Protection Agency on or before October

16,

1971, a bond or

other security in a form to be determined by the Agency, in

the amount of $220,000, which sum shall be forfeited to the

State of Illinois in the event the company does not comply

with the provisions of this order.

8. The petitioner shall file with the Agency, within fifteen days

after any release of effluent under this order, a full report

indicating the time and duration of the release, the volume and

concentration of the effluent, the volume of the receiving stream,

and BOD and suspended solids concentrations above and below the

point of discharge.

I, Regina Ryan, Clerk of the Board; certi~ythat the above

Order was entered by the Board on~y~September,l9.
