                                                         VILLAGE OF SHOREWOOD
                                                       OVERFLOW RESPONSE PLAN

1.        Purpose

The Overflow Response Plan is to ensure that every confirmed sanitary sewer overflow
(SSO) is adequately addressed to ensure that the effects of the overflow are minimized
with respect to impacts to public health and adverse effects on beneficial uses and
water quality of surface waters and customer service. This is required under s.283.55
(1)(dm) Wisconsin Statues and in accordance with the WPDES permit. This is
accomplished by:
        Immediate response to the SSO
        Minimize the effects of the SSO
        Provide containment and proper clean-up of the overflow
        Determining the cause of the SSO

2.        Background

The Village is committed to eliminate preventable Sanitary Sewer Overflows (SSOs) in
their collection system. This plan will provide procedures to respond to the SSOs. The
CMOM Plan requires an Overflow Response Plan (ORP). The ORP includes provisions
to ensure safety and public health are protected and notification and reporting is made
to the Wisconsin DNR and other agencies as required.

The primary objective of the ORP is to protect public health and the environment, to
satisfy regulatory agencies and discharge permit conditions which address procedures
for managing sewer overflows, and minimize risk of enforcement actions against the
Village.

The ORP presents a strategy for the Village to mobilize labor, materials, tools and
equipment to correct or repair any condition which may cause or contribute to an
unpermitted discharge. The major components of the ORP are:

     1.    Identification of known or potential overflow sites
     2.    Receipt of Information regarding a potential SSO
     3.    Dispatch
     4.    Overflow Mitigation, Containment and Cleanup
     5.    Notification and Documentation
     6.    Root Cause Failure Analysis

                                                    VILLAGE OF SHOREWOOD
                                                  OVERFLOW RESPONSE PLAN

Additional objectives of the ORP are as follows:
        Protect collection system personnel and wastewater treatment plant;
        Protect the collection system, wastewater treatment facilities, and all
          appurtenances; and
        Protect private and public property beyond the collection and treatment
          facilities.

3.    Identification of Overflow Sites

There are four gravity overflow sites in the Village of Shorewood as listed in Table D-1.
The overflow sites have a valve that is normally CLOSED. To prevent wastewater from
backing up into basements and creating an immediate health hazard, the valves may be
opened to flow to a storm sewer. These sites have specific procedures to respond to
and document overflows. This procedure can be found in Appendix F, Wet Weather
Procedure SOP. These sites are:

                                            Table D-1

4.    Receipt of Information Regarding an SSO

An overflow may be detected by Village employees or by
others. The Village is responsible to respond to any calls or
reports of a potential SSO and to provide immediate response             UNTIL FIELD
to investigate and/or correct reported sewer overflows.                 VERIFIED, THE
                                                                         REPORT OF A

           correct the problem.

5.        Dispatch
     a. Upon receipt of a notification that there could be an overflow OR in the event that
        heavy rains are predicted, the DPW will dispatch a designated employee to
        investigate the problem. This person shall investigate and confirm if there is an
        SSO. See Wet Weather SOP in Appendix F to respond to the specific sites with
        overflows.
     b. If a SSO is confirmed then it must be reported. See Number 7 - Notifications for
        detailed requirements. The DNR must be notified verbally or electronically
        within 24 hours and in writing within 5 days.
     c. Determine the cause of the overflow, (e.g. high flows, sewer line blockage, sewer
        line break, etc.);
     d. Identify and request, if necessary, assistance or additional resources to correct
        the overflow or to assist in the determination of its cause. See emergency
        contractor contact numbers in Table D-3.
     e. Estimate quantities of flow for the overflow.
     f. Estimate overflow quantities based on time and volume

6.       Overflow Mitigation, Containment and Cleanup

The following procedure will be followed to clean-up the SSO.
     a. Identify the destination of the overflow (storm sewer, street, specific location,
        river, lake)
     b. Secure the area to prevent contact by members of the public until the SSO has
        been addressed and cleaned up.
     c. Take immediate steps to stop or minimize the impact of the SSO,
            i.       Relieve Village sewer blockage by cleaning the sewer
           ii.       Install portable pump at the manhole and pump to another sewer manhole
                     if possible.
           iii.      Open Overflow Valves as noted in Table D-1. This can only be done with
                     the permission of the Village Manager or her or his designee.
           iv.       Call emergency contractors or other municipalities for assistance as
                     necessary. See Table D-3 and Table D-4.
     d. Request additional personnel, materials, supplies, or equipment that will expedite
        and minimize the impact of the overflow
     e. Cleanup of the overflow site shall be completed as soon as possible.
            i.       Secure the site – route traffic around if necessary.
           ii.       Take photos of the SSO.
           iii.      Where practical thoroughly flush the area and clean any sewerage or
                     wash-down water. Solids and debris may be flushed, swept, picked up or
                     transported for proper disposal. Liquids may be discharged to the sanitary
                     sewer.
     f. Notification to stakeholders needs to be completed for all SSOs. See Table D-2
        for Notification Contacts.
