actions, Because of its complex-
ity. the ove:rall Reilly cleanup in-
vestigation has been divided intO
a nwnber of phases called "oper-
able units," each of which has, or
will have, its own aerion plan.
The: plan for one of these units.
the St Peter Aquifer. is now
ready for public comment (The
other ope:rnble writs are in
various stages of cleanup.)
~Vhy is the MPCA dividing the
site into operable units?
~
The contamination at the Reilly
site occurred over many years
and through many avenues. As a
result, chemicals went deep intO
the ground. The sin: is underlain
by five separate aquifers, or
layers of earth and porous rock
containing ground water. These
aquifm are stacked on top of
one another, separated by various
confinin g layers, going down
hundrMs of feet below the
surface. Communip~' in the
Twin Cities western suburban
area get their drinking water
from these aquifers.
The Reilly site has contaminated
most of these aquifers to varying
degrees in the area of the site.
The ground water in each aquifer
"behaves" differently, moving in
somewhat different clirections.
Because cleanup will be different
for each aquifer. they are being
inve.stigated separately. The St.
Peter is the second layer down,
lying berween about 100 and 200
feet below the surfa.ce. The
contamination in this aquifer
needs to be removed., because it
has the potential to spread to
other drinking water supplies
and/or aquifers.
So what's the cleanup plan for
the St Peter aquifer?
EP A and rv1PCA propose to
pump out the contaminated
water from the aquifer and treat
it so that. it no longer poses a
health risk. The 'investigation
showed that a well in this aquifer
pumping an average of 65 to 100
gallons a minute would induce
ground water in the area to move
tOward the well and be drawn
out of the ground.
Eventually this would cmy all
the contmrination in the aquifer
to the well, effectively prevent-
ing it from spreading from the
Reilly site. The wau:r v.ill be
sent through the sanitary sewer
syStem to the Metropolitan
Waste Control Commission's
(MWCC) main treattnent facil-
ity, where the contaminants will .
be removed.
The well has been constrUcted
and teSted. and is ~dy to begin
pumping as soon as the public
has had a chance to comment on
this remedy.
How can you send chemically
contaminated water to a sewer.
plant?
The water from the pW11p-out is
fairly clean. V.,rh.i1e nor pure
enou gh to be used for d:rinkin g
Wa1eI', it is. for example, cleaner
than StOrnl nmoff. The contami-
nants it contains, primarily
polynuclear aromatic hycirocM-
bons (PAHs), are biodegradable
and can be t:re3I.ed by MWCC.
This is only an interim solution,
and it's likely that this WaICl'
may be treated on-site in the'
futUre. .
Why was this plan chosen?
Remedies in Superfund cl~anup~i
are evaluated against a number
of criteria. A5 Stated, this rem-
edy is only pan of the overall
remedy or cleanup for the Reilly
site; it's not the solution to the
whole problem. The plan was
carefully considered in light of
the following criteria:
1. This remedy providCs overall
protection of human health and
the environment by limiting the
further spread of contamination
within the aquifer.
2. Applicable local ~uire-
ments are complied with in thaI
the water will meet state surface.
water criteria when discharged
from the MWCC's treatment
plant.

-------
~
~
"1'
3. The rem~y will provide for
long-term effectiveness and
permanence by ensuring that th
pwnp-<:>ut will continue as lor.g
as necessary to prevent the
further spread of contamination
in the aquife.r.
4. Tne tOxiciry, volume, and
mob~~y of the contaminantS
preSC:1t in the aquifer v.ill be
effec:ively reduced over time by
the ?urnp-out.
..
5. The conStruction and imp'lem- .
entation of this remedy presents
no worker or communiry expo-
s~. nor any adverse environ-
me:-.ul irnp3.ctS.
6. T:-.~ :::chnolcgy fer this
rer..=-:y is proven, cost-effec-
rive, reliable, and easy to main-
tain.
7. The final criteria are state and.
community acceptan~. The
MPCA has agreed, to . this rem-
edy. and now the communi~ has
an opporrunity to review and
COIT'..,'nent on the proposed
re~edy before it becomes final.
In view of the health hazards
posed by the ground water
contamination from this site,
pumping and treating the water
i.s tWly the only practical
alternative.
How long will the pump-out
need to continue?
Water coming from the well v.ill
be tested pericxiically, and the
pump-<:>ut will continue until the
well proouces water that's \Vithin
state guidelines for drinkin g
water. TIlls may take as long as
30 ye.m, and possibly longer.
What about the rest of the
cJeanup (the other operable
units)?
The other partS of the overall
Reilly investigation relate to the
other aquifers involved. and
have their own investigations
and action plans. They are all in
va...;.ous st3ges of completicI:. but
basically, the same type of
pump-and-treat will be per-
formed, vvith minor variations,
for each aquifer:-
These aquifers are critical water
supplies for a sizAble portion of
the Twin Cities metro area. and
there's no question that they
mUSt be cleaned up and pro-
teeted from the further spread of
contamination related to the
Reilly site. Ground water moves
very slowly, and the cleanup i.s
keeping ahead of the problem.
When all the opc:rable units in
this project are complete and
pumping, the ground water
contamination in each aquifer
resulting from the Reilly site
should be well under contrOl.
What happens next?
With the release of this fact
sheet, the MPCA announ;:cs a
30-day public comment period
on this alre:rn.ative, to end June 1.
A public meeting is scheduled
fer May 16th (see the box on the

lowing the public comment

begin the pum~ut of the SL

modifications resulting from the
public's commentS.

As approved by the Corrrnissioner, in conrormance with app1icajie
Agency guidelines for system reliability, and in accordance w;t~
PART II, A.2. of this permit. the Corrrnission is authorized to
discnarge from emergency bypass points, outfall serial numcers
020, 030, 040, 060, 070 and 080.
The Commission shall, in accordance with PART II, A.I. of t'1is
permit. report in the remarks section or the Monthly Operat~on
Repor:, each eme~gency bypass event, the corresponding oU:~:lll
number, its duration, t:ie estimated volume, and estima:ed
concentrations for CBOD;, TSS, total phosphorus and ammonia based
on sampling of locations which are representative of the bypass.

Total Residual Chlorine
2.
If the daily total residual chlorine sample exceeds 0.1 mg/l, the
Commission shall immediately investigate the cause, take
appropriate remedial action and report the action and results on
the monthly discharge monitoring report. If the Mississippi
River elevation at Robert Street exceeds 697.5 feet. to protect
the integrity of the facility, the dechlorination facilities may
be removed from service. During these periods, the total
residual chlorine effluent limitation in PART I, B. and the f~rst
sentence in PART It C.2. shai1 not apply. The occurrence of such
an event sha 11 be reported to the Agency COlm1i ss i one!" as requ: red
by" PART II. A.l. and described in the monthly discharge
monitoring report.

Dissolved Oxyqen
~ .
3.
The effluent shall comply with the effluent limitation for
dissolved oxygen identified in PART 1, 8.1 when daily average
dissolved oxygen concentrations below discharge 010 are less than
5.5 1119/1 for two consecutive sample-days or when daily average
dissolved oxygen concentrations above discharge 010 are less than
6.0 mg/l for two consecutive sample-days. Dissolved oxygen
measurements in the river shall be evaluated within 12 hours
after each day's monitoring to determine when aeration of the
effluent will be required. When continuous river monitors are
used to determine compliance with this condition, measurements at
UM 826.6 and UM 831 shall be used to evaluate downstream
dissolved oxygen concentrations .and measurements at 'UM 836.8
shall be used to evaluate upstream dissolved oxygen
concentrations. This requirement shall only apply when da; 1y
average river flows' of 7,000 cubic feet per second or less oc~ur
for two consecutive days as measured by the U.S.G.S. Gauglng
Station at St. Paul.
