                                                                        Executive Summary

This Stormwater Pollution Prevention Plan (SWPPP) is prepared for the Milwaukee
Metropolitan Sewerage District (MMSD) North Service Facility located at 4830 North 32nd
Street in Milwaukee, Wisconsin. The MMSD has voluntarily prepared this SWPPP which
complies with the requirements for Tier 2 industrial facilities as set forth in Chapter NR216 of
the Wisconsin Administrative Code.

The current NR216 (Phase I) rules have an exclusion under the Intermodal Surface
Transportation Efficiency Act that postponed Wisconsin Pollutant Discharge Elimination System
(WPDES) permit application deadlines for some facilities that are owned or operated by
municipalities. The proposed Phase II storm water rules remove this exclusion. The MMSD
Wastewater Treatment Plants and Service Facilities may be required to obtain and comply with a
Tier 2 Stormwater Permit under the Phase II rules.

The preparation of this SWPPP reflects the MMSD’s commitment to clean water. The primary
purpose of this SWPPP is to identify potential sources of stormwater and non-stormwater
contamination and to identify appropriate best management practices to reduce or eliminate the
potential for storm water contamination.

This SWPPP:
    Describes the North Service Facility and presents a facility drainage base map (Section 2)
    Identifies a pollution prevention team responsible for implementation and maintenance of
      this plan (Section 2)
    Identifies potential sources of stormwater contamination including material storage and
      handling sites, parking and roadway areas, and rooftops (Section 3)
    Describes non-stormwater discharges (Section 4)
    Identifies source control best management practices including soil erosion / sedimentation
      control practices, good housekeeping practices, preventive maintenance practices,
      outdoor maintenance, visual inspection, spill prevention and response practices, and
      employee training (Section 5)
    Identifies storm water treatment / runoff reduction best management practices (Section 5)
    Describes monitoring requirements including evaluation of non-stormwater discharges,
      visual monitoring or storm water discharges, and annual facility site compliance
      inspections (Section 7)
    Presents a compliance schedule (Section 8)

The Milwaukee Metropolitan Sewerage District (MMSD) is committed to improving water
quality throughout its planning area. This Stormwater Pollution Prevention Plan (SWPPP) is a
product of that commitment. The MMSD has prepared this SWPPP to identify and reduce or
eliminate potential sources of stormwater contamination from the North Service Facility.

This Stormwater Pollution Prevention Plan (SWPPP) was prepared for the Milwaukee
Metropolitan Sewerage District North Service Facility at 4830 North 32nd Street, Milwaukee,
Wisconsin in accordance with the requirements for Tier 2 industrial facilities as set forth in
Chapter NR216 of the Wisconsin Administrative Code. A copy of the general Tier 2 permit is
presented in Appendix A of this SWPPP. The MMSD is not required to obtain a Stormwater
Discharge Permit from the Wisconsin Department of Natural Resources (WDNR) for the Service
Facility site because the facility does not have a Standard Industrial Classification Code
identified by the WDNR for regulation under the current program. The MMSD, however,
decided to voluntarily prepare this SWPPP to assist in identifying and implementing best
management practices that will help protect water quality.

The purpose of this SWPPP is:
      to identify potential sources of stormwater and non-stormwater contamination to the
        stormwater drainage system,
      to identify appropriate best management practices to reduce or eliminate the potential
        for stormwater contamination,
      to eliminate unauthorized non-stormwater discharges, and
      to develop an implementation schedule for the Permit requirements.

The pump station equipment is located inside. Pumps are exercised monthly by MMSD/United
Water personnel. Pumps are occasionally lifted out of their operating location and maintained.
The pump maintenance is conducted outside on a concrete paved area. Any spillage is typically
cleaned up after maintenance is completed.

The maintenance building is primarily used for equipment storage. Batteries for generators are
stored inside the maintenance building.

Outside material storage includes pipe sections, generators, stone, and various sewer and
construction materials.

                                              Section 4 - Status of Non-Stormwater Discharges

Non-stormwater discharges are discharges to the stormwater drainage system that do not consist
of stormwater.    Non-stormwater discharges are designated as either contaminated or
uncontaminated by the WDNR based on the source of the discharge. Typical sources of non-
stormwater discharge considered contaminated which are NOT authorized by the Tier 2
Stormwater Discharge Permit include:
           vehicle and equipment washwater,
           sewerage,
           contact cooling water,
           process wastewaters,
           air compressor discharges,
           spills or leaks, and
           discharges of process waters from oil water separators.

Discharges which are not authorized by the Permit must either be eliminated or covered by a
separate permit.

Non-stormwater discharges which are considered uncontaminated and do not require separate
permitting include:
            water line flushing,
            landscape irrigation,
            diverted stream flows,
            uncontaminated groundwater infiltration,
            uncontaminated pumped groundwater,
            discharges from potable water sources,
            foundation drains,
            air conditioning condensation ,
            irrigation water,
            lawn watering,
            flows from riparian habitats and wetlands, and
            discharges form fire fighting activities.

MMSD North Service Facility was visually inspected for non-stormwater discharges on January
7, 2003. Evidence of non-storm water discharges was not observed.

    Source Area Control Best Management Practices

    Source area control best management practices (BMPs) are practices designed to prevent
    stormwater from becoming contaminated at the facility. The source area control BMPs
    emphasize prevention rather than treatment of contaminated stormwater. Source area control
    BMPs to be implemented at the MMSD North Service Facility are identified in Table 3.

     TABLE 3: SOURCE AREA CONTROL BEST MANAGEMENT PRACTICES FOR MMSD NORTH SERVICE FACILITY
     Soil Erosion / Sedimentation Control Practices

     a. Inlet filters will be installed in the storm sewer inlets. The inlet filters will be inspected monthly
        and cleaned or replaced as necessary.
     Good Housekeeping Practices

     a. Trash will be stored in covered dumpsters or inside.
     b. Paved areas will be swept on a regular basis. The sweeping frequency will vary based on the
        sediment accumulation rate. All paved areas will be inspected quarterly. Sweeping will be
        conducted when sediment accumulation is observed. Sweeping should be conducted as early in
        the spring as possible to collect sediment and salt accumulation from winter months. Semi-
        monthly sweeping may be necessary in the spring months. Sweeping will continue throughout
        the winter as weather permits.
     c. Pumps will be placed on an absorbent pad or inside a drip pan during outside maintenance.
     d. Pump maintenance areas will be inspected after maintenance. Any observed spillage will be
        promptly cleaned up.
     e. The facility will be kept clean of miscellaneous debris. The facility will be inspected monthly
        and cleaned up as necessary. Employees will be reminded to properly dispose of miscellaneous
        debris.
     Preventive Maintenance Practices

     a. Facility equipment and systems capable of breakdown or failures resulting in discharge of
        pollutants to areas exposed to precipitation should have a regular maintenance program. The
        program should include: periodic inspections or test for leaks, deterioration of seals or other parts
        which could result in leaks or spills: appropriate and timely adjustment, repair or replacement of
        components; maintenance of complete records of inspections, and maintenance activities. The
        preventive maintenance program should include facility transformers, generators, and other
        equipment with the potential to leak.
     b. Storm sewer catch basins will be inspected quarterly and cleaned when nearing 40 percent of
        capacity.

     a. The application rate of deicers will be tailored to the use of the area. Higher rates should only be
        used for the primary entrance and walkway and a lower rate should be used for remote entrances
        and parking areas.
     b. Drivers and maintenance personnel will be trained to improve deicer efficiency and reduce losses.
     c. Calcium chloride and calcium magnesium acetate should be used where practicable as the
        primary de-icing agent.
     Visual Inspections

     a. Monthly inspections will be conducted to evaluate the facility for evidence of, or the potential for,
        pollutants entering the drainage system. The purpose of the inspection is to confirm that potential
        pollution sources are being properly controlled. A record of the inspection will be completed and
        retained with the SWPPP. A monthly inspection documentation form is located in Appendix B.
     Spill Prevention and Response Practices

     a. Any observed leak or spill will be immediately responded to, contained, cleaned-up, and as soon
        as possible the cause repaired or addressed.
     b. All materials will be handled with care to prevent spillage.
     c. A drain seal mat will be stored in the office building basement for use in case of an emergency.
        The mat will be used to prevent spilled or leaked material from entering storm drains. MMSD
        maintenance personnel will be trained in the use of the mat.
     d. A spill kit will be stored on site for use in case of an emergency. The spill kit will include
        absorbent socks and mats. MMSD personnel will be trained in the proper use of the absorbent
        materials.
     Employee Training

     a. An employee training program will be conducted annually for maintenance personnel. The
        SWPPP information will be reviewed with new maintenance employees. The following subjects
        may be included in the training:
                     Objectives and requirements of the SWPPP
                     Spill prevention, response, and reporting procedures, and good housekeeping
                       practices
                     Proper procedures for materials storage
     b. General information related to this SWPPP and the best management practices should be provided
        to all employees annually through a newsletter, inter-office memorandum, or other training
        program.

    Stormwater Treatment/Runoff Reduction Best Management Practices

    Stormwater treatment BMPs are practices which treat potentially contaminated stormwater
    runoff. Specific stormwater treatment practices identified in the Tier 2 Permit are for
    stormwater discharges significantly contaminated with petroleum products or sediment from
    eroding areas. Stormwater runoff from the MMSD North Service Facility is not expected to
    be significantly contaminated with petroleum products or sediment.

    Stormwater runoff reduction practices reduce the amount of stormwater discharging from the
    site by directing runoff to areas where it can be collected, stored, and/or infiltrated.

    The MMSD should consider implementation of runoff reduction practices for stormwater
    runoff from the paved areas of the North Service Facility.

    The one acre paved parcel borders a vegetated area and is adjacent to Lincoln Creek. Runoff
    reduction practices considered practical for this site are rain gardens and porous pavement.
    The runoff reduction practices will reduce the volume of storm water discharged directly to
    Lincoln Creek as well as improve water quality.

    Runoff from the existing storm sewer system could be diverted into a rain garden area
    constructed along the eastern border of the facility. Adjustments to the current storm sewer
    system are necessary to direct water to the proposed garden site.

    Porous pavement is an additional practice that could be used in areas of the site with low
    vehicular traffic. This practice should be evaluated when pavement replacement or
    maintenance of the existing pavement is scheduled.

Following the implementation of the source area controls identified in Section 5 of this SWPPP
and the elimination of non-stormwater discharges, some residual pollutants are likely to be
present in the stormwater discharges from the MMSD North Service Facility. Implementation
of this plan and best management practices are believed to be adequate to minimize most
pollutants in the facility’s runoff.

Based on a review of the potential source area and proposed BMPs, minor amounts of total
suspended solids, oil, salt, metals, and organics may be present in the stormwater discharged
from the facility.

                                                   Section 7 - Facility Monitoring Requirements

The Tier 2 Permit requires implementation of a monitoring program to evaluate the effectiveness
of the facility’s pollution prevention activities. The required monitoring includes an evaluation
of non-stormwater discharges, stormwater discharge observations, and an annual facility site
compliance inspection. The Permit should be referred to for more detailed information related to
monitoring.

EVALUATION OF NON-STORMWATER DISCHARGES

Stormwater outfalls must be evaluated for non-stormwater discharges to the drainage system.
The evaluations will be conducted by visual observation of the facility outfall locations.

    Frequency: Twice per year
    Weather conditions: Conduct evaluations during dry weather periods
    Procedures:
           1. Walk the facility and inspect the three outfall locations.
           2. Identify any instances of dry weather flow, stains, sludge, color, odor, or other
              indications of a non-stormwater discharge.
           3. Record observations, date of evaluation, outfall location. If signs of unauthorized
              non-stormwater discharge are observed, describe actions to be taken to eliminate
              or permit the discharge. A form for recording the observations is presented in
              Appendix B.
    Reporting: The results of the non-stormwater evaluations must be maintained with the
                Annual Facility Site Compliance Inspection Report and maintained as part of
                this SWPPP.

ANNUAL FACILITY SITE COMPLIANCE INSPECTION

An annual facility site compliance inspection will be conducted to verify that the site drainage
conditions and potential pollution sources identified in the SWPPP remain accurate, and that the
best management practices prescribed in the SWPPP are being implemented, properly operated,
and adequately maintained. The annual facility site compliance will be recorded on a report
form.

    Frequency: Annual
    Weather Conditions: No requirements
    Procedures:
          1. Walk the entire facility to review the stormwater drainage patterns, identify the
              potential stormwater pollution sources, and inspect the BMPs.
          2. Compare the results of the site inspection to the information contained in this
              SWPPP
          3. Identify any BMPs which require improvement and, if necessary, identify
              additional BMPs.
          4. Revise the SWPPP as necessary to update the information.

           5. Record the results of the inspection including the following information: the
              inspection date, names of the inspection personnel, scope of the inspection, major
              observations, and revisions needed in the SWPPP.
    Reporting: The results of the Annual Facility Site Compliance Inspection must be
               maintained as part of this SWPPP. An Annual Facility Site Compliance
               Inspection Report Form, prepared by WDNR, is located in Appendix B.


VISUAL MONITORING OF STORMWATER DISCHARGES

Stormwater discharges from each outfall must be visually evaluated for signs of potential
contamination. Visual monitoring will be conducted if required by WDNR under future permit
requirements.

   Frequency: As required by WDNR under future Permit requirements
   Schedule: As required by WDNR under future Permit requirements.
   Weather Conditions: Within the first 30 minutes of rainfall runoff, or as soon as possible,
                          not after the first 60 minutes of runoff.
   Procedures:
          1. During the first 30 minutes of rainfall runoff collect a sample of the stormwater
              discharging from or collecting in each outfall location in a clear container.
          2. Evaluate the stormwater sample for signs of: color, odor, turbidity, floating solids,
              foam, oil sheen, or other obvious indicators of stormwater pollution.
          3. Record observations, date of inspection, name of person conducting the
              evaluation. A quarterly Visual Inspection Field Sheet, prepared by the WDNR to
              record observations, is located in Appendix B.
          4. If signs of contamination are observed, identify the probable source of the
              contamination and actions to be taken to reduce or eliminate the source.
Reporting: The results of the stormwater evaluations must be maintained with the Annual
             Facility Site Compliance Inspection Report and maintained as part of this SWPPP.

The SWPPP should be reviewed and amended on a regular basis. The WPDES permit requires
that the SWPPP be amended under the following circumstances:

Significant Increases of Pollutant Exposure

The SWPPP must be amended if changes at MMSD North Service Facility will result in
significant increases in the exposure of pollutants to stormwater discharged either to the waters
of the state or to stormwater treatment devices.


Control Provisions are Ineffective

The SWPPP must be amended if it becomes apparent that the control provisions identified in the
plan are ineffective in controlling stormwater pollutants. The site observations and monitoring
that are to be conducted on a regular basis are intended to identify potential deficiencies.


WDNR Notification

The SWPPP must be amended if the WDNR finds the SWPPP to be ineffective in achieving the
conditions of the Tier 2 Stormwater Permit. (Note: This is a voluntary program MMSD is
undertaking and therefore regulatory reporting and notification requirements are unnecessary at
this time.)
                                                                                              .
