Description

of

Envirqjimentat

tm~act

The owners of

the

Lincoln

Mobile RomePait,

Sangamon County, Illinois,

operate

a

privately

owned

Wastewater Treatment Facility

(WWTF) for the

residents

ofthe park. The

WWTF

is

a three-cell

aerated

lagoon followed by a

sand filter

and

disinthction

fecilkies.

The

lagoon cells are divided by a

proprietary

fabric

baffle

wall.

The wall prevents short-circuiting of

the

lagoon flow

from

cell

to cell. The

aerators

are pontoon- mounted units.

The owner has an NPDES permit with an outfall to the

Sangamon

River.

The

lagoon has an average

depth

of

11

feet(allowing for 2

feet

of

freeboard).

The

effluent

is

pumped from

the

lagoon

to

the sand

filter. There is

one

operational draw

off for

the pump

station located

approximately

4.5

feet up

from

the lagoon

bottom.

Another existing

draw

off

located

approxImately

2 feet

from

the bottom

is non-functional. There

are

no additional

thaw

offpipes.

The

WWTF

was

flooded

by the Sangamon River in 2002. The

flood

damaged

a mooring for the

baffle

curtain,

and

also

Ibuled

the sand

filter with

riversediment.

The

owner is

proposing to lower the

lagoon

6-6.5

feet in

order

to make the

repairs

to the baffle

curtain

mooring, and

to

install

additional

drawoffs

in

the

pump station. The owner is requesting a

variance

fromthe

IRPA

to

by-pass

the filter and

disinfection processes,

and

discharge the

effluent to the

Sanganion

River.

The filter

and disinf~ction

process

are sized by

design standards

foran averageof5~.0Q0

gallons/day. ft

is not feasible to

draw

down the lagoon through the filter

and

disinfection

process due to the

time required for a

draw-down.

The maximum discharge

limit

as set by the

NPDES

permit is 100.000

gallons/day. The average influent to the lagoon

is

53,000

gallons/day. The

net

effect would

be

a pumpage

of

approximately 50,000 gallons/day to effluent.

This would require

70 days to

reach

the

desired

lagoon

level for the

repairs.

Also,

this

does

not

account

for excessive flows, which

occur

during

wet weather. The

owner

is in a difficult position to

fluctuate

the

lagoon

levels

even in a normal

operational

stra*e~’

to

provide storage in anticipation

of

wet

weather conditions.

Attachment #1

is a

summary

of

the

Discharge Monitoring

Report.c (DMR’S)

from September

2003 to January, 2005,

owners

contract

operator. The regulated discharge

limits for

BOD.

TSS, and

focal coilforms, are 25 ppm,

37 ppm,

and

400/100 ml respectively.

The

maximum

discharge limits

for BOD

and

TSS

arc

40

ppm and

45 ppm respectively.

The

averages

for the

treated

effluent for

the

16-month

period

are

S ppm BOD

and

5 ppm TSS.

Field

samples

were

taken

on

April

2112005

to determine

the

water quality in the lagoon in

Cell

A~3

prior to discharge to the sand filter.

Samples were taken at

1

foot intervals

ofdepth starting at 6

Inches

deep

to approximately

10 foot deep. The

testing

was done to

determine a profile ofthe water quality for

the

desired depth of

dc-watering

requested by the owner. A summary ofthe

lab

results are in

Attachment

#2~.

The SQl) at all depths was tested to be

lower than

the

regulatory

limit of 12 ppm. The

TSS

varied

between

46 ppm at

6

inches to

64 ppm at 7-5

feet.

The average of the samples TSS is 53 ppm. The focal

coliforms

tested

at 4500/100 ml.

The samples show that

the

BOD

concentrations would

have no adverse

impact

on the

environment

if

IEPA

alloweda

variance

to

discharge without

filtration.

However,

the

TSS

samples

show that there

would

be

a minimal

environmental

impact to the receiving

water

if

a variance

were allowed.

Suspended solids

are a

physical

indicatorof

wastewater

quality.

These

are

regulated to reduce

discharge ofsolidsto open waters in order to prevent

anaerobic

conditions

and

sludge deposition. The

owneris

proposing

to

pump

the

lagoon level down

6.5

feet from

the

present level.

This would require

puinpage of

approximately

3.5

million gallons. The pumpage would

need to

beat arate

of

about

500

gallons!

minute

for a

draw

down period of five-six days.

Thus, the

flow to the

river would

be about 720,000

gallons/day. This

would result inan

extra

loading ofsolids to the river ofabout SO

pounds

per day above

the

regulatory

limit. The total

extra

loading forten

days would

be about 400 pounds ofsolids.

ifthe

existing

treatment

process is considered

(using the

avg TSS of

5

ppm), normally

the plant is

below the

discharge

limit of solids by a

factorof 32 ppm, or 14

pounds per

day

at an

average flow

of

53,000 gpd.

Thus, the

net

effect is

that

theywould

produce 400 pounds

of

extra

solids by not filterIng

for a

five

day

period,

yet would

be able to recover by

normal

plant operations in a period of

about

one month (30

days

X 14 pounds

per day

420

pounds).

The short term

negative

impact ofsolids loading

can

be considered minor in comparison to the

long term

benefit ofmaking

the plant improvements to maintain the

high

quality

of

effluent over

the long

term.

The fecal coliform

concentration

is used as

an indicatorofpathogenic organisms

in

wastewater.

Disinfection

is used

to lower focal coliforTa

counts during

the

season

from May-October because ofthe

recreational

use

of

the

river,

The disinfection exemption

is

in

effect

from

Novemberto May. It

has

recently

expiredfor this season

(today’s date

May 4).

The

negative impact

ofallowing

higher

focal

concentrations during

the

recreational

season Is that

the

water

could be

Ingested by

a person being submerged in

the

river at

the

location

of the discharge. There

is

risk

in

allowing

a higher concentration limit for a

short period

oftime

(5-6

days).

However, that risk

is

minimal

considering

the

season

is

still cool in temperature,

and

also

offset

by thenormal

seasonal risk of

relaxing the

limits fora six month

period.

A

variance

for this

requirement

would have minor

environmental

impact in

comparison with the positive impact ofthe-proposed

improvements.

In

summary,

the owner is

requestinga

temporary

variance

from

the NPDES limits

for

TSSand

focal

coliforms for a

short term period

in

order

to

bypass

the

flows

and

complete

the

necessary repairs.

The

owner is proposing

that

the TSS

shall not exceed

60 ppm as a result ofthe

bypass

operations.
