Note: This SWP3 was prepared using the U.S. Environmental Protection Agency (EPA) SWP3 Template, Version 2.1 and was modified to meet the requirements of the Ohio Environmental Protection Agency (OEPA) General Permit for Storm Water Discharges Associated with Construction Activity Under the National Pollutant Discharge Elimination System (OHC000005), issued April 23, 2019, effective April 23, 2018, and expiring on April 22, 2023.

EPA SWP3 Template, Version 2.1 5

SECTION 1: PERMIT COVERAGE, REQUIREMENTS, AND RESPONSIBLE PARTIES

1.1 Permit Coverage

This Stormwater Pollution Prevention Plan (SWP3) was developed to cover the construction activities associated with the Perry’s Victory and International Peace Memorial, Restoration of North and South Seawalls Project. The Ohio Environmental Protection Agency (OEPA) General Permit for Storm Water Discharges Associated with Construction Activity Under the National Pollutant Discharge Elimination System (OHC000005) (the General Permit), issued April 23, 2019, effective April 23, 2018, and expiring on April 22, 2023 is included in Appendix A. Coverage under the General Permit covers all new and existing discharges composed entirely of storm water discharges (and approved non-stormwater discharges) associated with construction activity that enter surface waters of the state or a storm drain leading to surface waters of the state.

A notice of intent (NOI) for coverage under the General Permit was submitted to OEPA; a copy of the NOI is included in Appendix B. In accordance with the General Permit, the NOI was submitted a minimum of 21 days prior to the anticipated start of construction.

Coverage under the General Permit is not effective until an approved letter granting coverage from the director of OEPA is received. Once received, authorization from the OEPA will be kept in Appendix B.

1.1.1 Co-Permittee

Where one operator has already submitted an NOI prior to other operator(s) being identified, the additional operator shall request modification of coverage to become a co-permittee. The co-permittees shall be covered under the same facility permit number.

The General Contractor must obtain coverage under the General Permit, as a co-permittee, prior to engaging in construction activities at the Site. Coverage under the General Permit is not effective until an approval letter granting coverage from OEPA is received by the applicant.

A copy of the General Contractor’s NOI, once submitted, shall be included in Appendix B. Once received, the General Contractor’s authorization from the OEPA will be kept in Appendix B.

1.2 Plan Availability

This SWP3 shall be retained on-site during working hours and made available immediately upon request of the OEPA or other Agencies Having Jurisdiction (AHJ). All NOIs, general permit approval for coverage letters, and SWP3s are considered reports that shall be available to the public in accordance with the Ohio Public Records law. The permittee shall make documents available to the public upon request or provide a copy at public expense, at cost, in a timely manner.

1.3 Plan Revisions/Amendments

Ohio EPA may notify the permittee at any time that the SWP3 does not meet one or more of the minimum requirements of the General Permit. Within 10 days after such notification, the permittee is required to make the required changes to the SWP3 and shall submit to Ohio EPA the revised SWP3 or a written certification that the requested changes have been made.

The permittee shall amend the SWP3 whenever there is a change in design, construction, operation or maintenance, which has a significant effect on the potential for the discharge of pollutants to surface waters of the state or if the SWP3 proves to be ineffective in achieving the general objectives of

EPA SWP3 Template, Version 2.1 6 controlling pollutants in storm water discharges associated with construction activity. SWP3 Amendments shall be logged in Appendix C.

1.4 Permit Termination

The terms and conditions of the General Permit remain in effect until a signed Notice of Termination (NOT) form is submitted. Failure to submit an NOT constitutes a violation of the General Permit. All permittees shall submit an NOT form within 45 days of completing all permit requirements.

Additional Project Information

Is the project/site located on Indian country lands, or located on a property of religious or cultural significance to an Indian tribe?

☐ Yes ☒ No

The project will repair and restore 1,900 feet (ft) of north seawall and 1,500 ft of south seawall at the Park located in Put-in-Bay, Ohio, on South Bass Island in Lake Erie. Years of wave action, ice loading and geological processes have deteriorated and severely undermined the two seawalls resulting in the creation of sink holes and unsafe conditions in certain locations.

Stormwater issues, including clogging of drains and flooding of park property due to storm events and elevated lake levels, have also been identified.

As part of this project, the seawalls will be raised including maximum 12” increase to the North Seawall and maximum 18” increase to the South Seawall. The project also includes site improvements, including a new sidewalk along the North Seawall and replacement of the existing sidewalk along the South Seawall.

Existing stormwater drainage facilities adjacent to the seawalls are deficient. Multidirectional flow allows lake water into the Park during high water levels. Improvements to the stormwater drainage system are necessary to prevent lake water from entering the Park during high water levels and to reduce maintenance requirements. The stormwater system improvements will include new catch basins, piping, two packaged pump stations and one vortex separator treatment structure. Additionally, the updated stormwater system includes abandonment of

EPA SWP3 Template, Version 2.1 10 several of the existing gravity outfalls (to reduce flooding associated with backwater from Lake Erie into the Park), with improvements to those outfalls that remain.

SECTION 3: DOCUMENTATION OF COMPLIANCE WITH OTHER FEDERAL REQUIREMENTS

3.1 Endangered Species Protection

Consultations with US Fish and Wildlife Services (USFWS) and the Ohio Department of Natural Resources – Division of Wildlife (ODNR DOW) have occurred to evaluate potential effects to federally-listed (Endangered Species Act [ESA]) and state-listed special status species and designated critical habitats.

To avoid adverse impacts to Indiana bat, northern long-eared bat, and Lake Erie watersnake, NPS shall implement protection measures as recommended by USFWS and ODNR DOW. These include the following:

• To avoid adverse impacts to Indiana bat, and northern long-eared bat, tree-clearing activities shall be restricted to between October 1 and March 31.

• To prevent adverse effects of construction activities to the Lake Erie watersnake, a biological monitor shall be present onsite as recommended by ODNR DOW. If the species is encountered during the proposed project, work would immediately cease and ODNR DOW and USFWS would be notified. [to be updated pending further discussions with ODNR]

Due to the urgency of the proposed project, and to reduce the duration of time of in-water work, NPS has requested and received ODNR DOW permission to perform work within the restricted periods of April 15 through June 30. Adverse impacts to federally-listed and state-listed threatened and endangered species are not anticipated as a result of the proposed project.

Relevant documentation related to endangered species is included in Appendix H.

3.2 Historic Preservation

The proposed project area, which is defined as the Park property boundary and the in-water temporary workspace which extends 150 feet waterward from the North and South Seawalls, is equivalent to the Area of Potential Effects, as defined in Title 36 of the Code of Federal Regulations Part 800.16(d) (36 CFR 800.16(d)). Cultural resources that are listed in or eligible for listing in the National Register of Historic Places (NRHP) are defined as historic properties in 36 CFR 800.16(l) for purposes of the Section 106 process.

Cultural resources and historic properties, however, are not interchangeable definitions, and will be differentiated when applicable.

A terrestrial and aquatic Phase I archaeological survey of the project workspaces was conducted June 1 to June 10, 2020. Eleven archaeological resources were found in the proposed project area, including a historical-age midden and 10 isolated finds, but none of the resources were recorded as a site or qualify as historical properties (Section 3.02.1). One historical property—the Perry’s Victory and International Peace Memorial (NRHP Reference No. 66000118 and 15000185) (the property)—was identified in the proposed project area (Section 3.02.2). The property is a cultural landscape comprised of a designed landscape with historical buildings and structures, and historical viewsheds. Historical viewsheds, which are also part of the setting, convey a feeling associated with significant events in American military history that occurred during the Battle of 1812 on Lake Erie.

No significant archaeological resources are in the project area. Soils in the terrestrial portion of the project area have been heavily disturbed, likely the result of fill and construction-related activities during the construction of the Monument and Park. Short-term impacts to submerged archaeological resources— would be avoided by implementing a 5-meter (15-foot) avoidance buffer during construction. In the event of an unanticipated discovery during construction, archaeological monitoring would be implemented. Therefore, no significant short-term or long-term adverse impacts are anticipated.

EPA SWP3 Template, Version 2.1 14

The project would result in no adverse impacts to the cultural landscape. Any change that may occur would be beneficial, and any minimal negative changes would be temporary and reversed to the preexisting condition after completion. Any changes, in particular the proposed sidewalk, seawall lights, and Park furniture, are compatible with design recommendations in the design recommendations in the 2018 Cultural Landscape Treatment Plan, and will have no adverse effects on the historic property.

The National Environmental Policy Act of 1969 process will be used in substitution to comply with Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation’s implementing regulations at (36 CFR 800.8 (c)). Materials required to comply with Section 106 will be included in the forthcoming Environmental Assessment.

Relevant documentation related to historic property preservation (once received) will be included in Appendix I.

4.8 Dewatering Practices

There shall be no turbid discharges to surface waters of the state resulting from dewatering activities. If trench or ground water contains sediment, it shall pass through an effective sediment control device, prior to being discharged from the construction site. Ground water which does not contain sediment or other pollutants is not required to be treated prior to discharge. However, care must be taken when discharging ground water to ensure that it does not become pollutant-laden by traversing over disturbed soils or other pollutant sources.

Filter Bag Description: Discharge from dewatering activities will be directed through a sediment filter bag when needed.

Maintenance Requirements

The sediment filter back should be inspected for tears and repaired or replaced, as needed.

Design Specifications

See detail in Site Plans.

4.9 Site Stabilization

Stabilization of disturbed areas shall, at a minimum, be initiated in accordance with the time frames specified in the following tables.

Permanent Stabilization Area requiring permanent stabilization Time frame to apply erosion controls Any areas that will lie dormant for one year or more

Within seven days of the most recent disturbance

Any areas within 50 feet of a surface water of the state and at final grade

Within two days of reaching final grade

Other areas at final grade Within seven days of reaching final grade within that area

Temporary Stabilization Area requiring temporary stabilization Time frame to apply erosion controls Any disturbed areas within 50 feet of a surface water of the state and not at final grade

Within two days of the most recent disturbance if the area will remain idle for more than 14 days

Any disturbed areas that will be dormant for more than 14 days but less than one year, and not within 50 feet of a surface water of the state

Within seven days of the most recent disturbance within the area For residential subdivisions, disturbed areas must be stabilized at least seven days prior to transfer of permit coverage for the individual lot(s).

Disturbed areas that will be idle over winter Prior to the onset of winter weather

EPA SWP3 Template, Version 2.1 19

Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed.

Permanent and temporary stabilization are defined as follows:

• “Permanent stabilization” means the establishment of permanent vegetation, decorative landscape mulching, matting, sod, rip rap and landscaping techniques to provide permanent erosion control on areas where construction operations are complete or where no further disturbance is expected for at least one year.

• “Temporary stabilization” means the establishment of temporary vegetation, mulching, geotextiles, sod, preservation of existing vegetation and other techniques capable of quickly establishing cover over disturbed areas to provide erosion control between construction operations.

“Final stabilization” means all soil disturbing activities at the site are complete and a uniform perennial vegetative cover (e.g., evenly distributed, without large bare areas) with a density of at least 70 percent cover for the area has been established on all unpaved areas and areas not covered by permanent structures or equivalent stabilization measures (such as the use of mulches, rip-rap, gabions or geotextiles) have been employed. In addition, all temporary erosion and sediment control practices are removed and disposed of and all trapped sediment is permanently stabilized to prevent further erosion.

Lawn Seeding ☒ Vegetative ☐ Non-Vegetative ☐ Temporary ☒ Permanent Description: Lawn areas that are disturbed will be seeded in accordance with the stabilization timelines above. Area will be seeded and maintained so that no bare areas are left once grass is growing.

Maintenance Requirements

Install straw mulch to prevent loss of seed. Water regularly until area has been fully stabilized.

Design

Paving ☐ Vegetative ☒ Non-Vegetative ☐ Temporary ☒ Permanent Description: Walkways and driveways will be paved with asphalt, concrete, and/or pavers as the final work in the area. Impervious area will prevent sediment migration.

Maintenance Requirements

Areas will be swept of sediment if there is any track out during construction in other areas.

5.2 Spill Prevention and Response

The General Permit does not relieve the permittee of the reporting requirements of Title 40 of the Code of Federal Regulations (“CFR”) Part 117 and 40 CFR Part 302.

In the event of a spill or other unintended release in excess of reportable quantities, the spill must be immediately cleaned, properly disposed of, and reported in accordance with local, state and federal reporting requirements. The discharge of hazardous substances in the stormwater discharge(s) from the construction site must be minimized through implementing the controls included in the SWP3. In no case, during any 24-hour period, may the discharge(s) contain a hazardous substance equal to or in excess of reportable quantities.

40 CFR Part 117 sets forth a determination of the reportable quantity for each substance designated as hazardous in 40 CFR Part 116. The regulation applies to quantities of designated substances equal to or greater than the reportable quantities, when discharged to surface waters of the state. 40 CFR Part 302 designates under section 102(a) of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, those substances in the statutes referred to in section 101(14), identifies reportable quantities for these substances and sets forth the notification requirements for releases of these substances. This regulation also sets forth reportable quantities for hazardous substances designated under section 311(b)(2)(A) of the Clean Water Act (CWA).

Spill kits should be available in multiple locations on-site for spill cleanup and response.

EPA SWP3 Template, Version 2.1 22

Employee Training: All employees will be trained via biweekly tailgate sessions regarding the correct procedures for spill prevention and control. Notices that state these practices will be posted in the office trailer, and the individual who manages day-to-day site operations will be responsible for seeing that these procedures are followed.

Spills: All spills will be cleaned up immediately upon discovery. Spent absorbent materials and rags will be hauled off-site immediately after the spill is cleaned up for disposal. Spills large enough to discharge to surface water will be reported to the National Response Center at 1-800-424-8802.

Material Safety Data Sheets (MSDS): MSDS’s, a material inventory, and emergency contact information will be maintained at the on-site project trailer.

5.3 Material Storage Areas

Construction equipment and maintenance materials will be stored at the combined staging area and materials storage areas. Silt fence will be installed around the perimeter to designate the staging and materials storage area. A watertight shipping container will be used to store hand tools, small parts, and other construction materials; including hazardous materials.

Nonhazardous building materials and construction scrap material will be stored in a separate covered storage facility adjacent to the shipping containers.

Large items, such as new catch basins, stormwater drainage pipe, etc. will be stored in the open in the material storage area. Such materials will be elevated on wood blocks to minimize contact with runoff.

5.3.1 Pesticides, Herbicides, Insecticides, Fertilizers, and Landscape Materials

Comply with manufacturer’s recommendations for storage.

Provide cover, either in enclosed storage facility or under a temporary roof.

Fertilizers will be applied according to manufacturer’s recommendations.

Material will be stored in an enclosed storage facility or under a temporary roof.

5.3.2 Diesel Fuel, Oil, Hydraulic Fluids, Other Petroleum Products, and Other Chemicals

Comply with manufacture’s recommendations for storage.

Petroleum products will be stored in water tight containers in an enclosed storage facility or under a temporary roof.

Clean up spills immediately.

5.4 Fueling and Maintenance of Equipment or Vehicles

All major equipment/vehicle fueling and maintenance will be performed off-site. When vehicle fueling must occur on-site, the fueling activity will occur in the staging area. If fuel tanks are to remain on-site, tanks should be double-walled with appropriate secondary spill containment, signage, and a fire extinguisher shall be maintained at the site.

Only minor equipment maintenance will occur on-site. All equipment fluids generated from maintenance activities will be disposed of into designated drums and properly stored prior to proper disposal. Absorbent, spill-cleanup materials and spill kits will be available at the combined stating and material storage area. Drip pans will be placed under all equipment receiving maintenance and vehicles and equipment parked overnight.

EPA SWP3 Template, Version 2.1 23

Equipment fueling will only be allowed in designated locations in the staging area, away from surface water and stormwater inlets. Fuel and oil will be kept under cover, spill kits will be provided, and personnel will be trained to respond to fuel and oil spills.

5.4 Washing of Equipment and Vehicles

Equipment and vehicle washing will be limited and will only be allowed in designated areas, away from surface water and stormwater inlets. Wash areas will have perimeter erosion control measures installed to prevent sedimentation. No detergents will be used.

5.5 Material Handling and Waste Management

All waste materials will be collected and disposed of into metal trash dumpsters in the materials storage area. Dumpsters will have a secure watertight lid, be placed away from stormwater conveyances and drains, and meet all federal, state, and municipal regulations. Only trash and construction debris from the site will be deposited in the dumpster. No construction materials will be buried on-site. All personnel will be instructed, during tailgate training sessions, regarding the correct disposal of trash and construction debris. Notices that state these practices will be posted in the office trailer and the individual who manages day-today site operations will be responsible for seeing that these practices are followed.

5.5.4 Hazardous or Toxic Waste

All hazardous waste materials such as oil filters, petroleum products, paint, and equipment maintenance fluids will be stored in structurally sound and sealed shipping containers, within the hazardous materials storage area. Hazardous waste materials will be stored in appropriate and clearly marked containers and segregated from other non-waste materials. Secondary containment will be provided for all waste materials in the hazardous materials storage area and will consist of commercially available spill pallets. Additionally, all hazardous waste materials will be disposed of in accordance with federal, state, and municipal regulations. Hazardous waste materials will not be disposed of into the on-site dumpsters. All personnel will be instructed, during tailgate training sessions, regarding proper procedures for hazardous waste disposal. Notices that state these procedures will be posted in the office trailer and the individual who manages day-to-day site operations will be responsible for seeing that these procedures are followed.

5.5.6 Sanitary Waste

Temporary sanitary facilities (portable toilets) will be provided at the site throughout the construction phase. The toilets will be in the staging area. The portable toilets will be located away from a concentrated flow paths and traffic flow and will have collection pans underneath as secondary containment. Portable toilets will be located away from surface waters and stormwater inlets and will be secured to the ground.

5.6 Designated Washout Areas

A designated temporary, above-grade water-tight concrete washout will be used. The temporary concrete washout area will have sufficient containers and volume to contain all liquid and concrete waste generated by washout operations. The washout area will be lined with plastic sheeting at least 10 mils thick and free of any holes or tears. Signs will be posted marking the location of the washout area to ensure that concrete equipment operators use the proper facility.

EPA SWP3 Template, Version 2.1 24

Concrete pours will not be conducted during or before an anticipated storm event. Concrete mixer trucks and chutes will be washed in the designated area or concrete waste will be properly disposed of off-site. When the temporary washout area is no longer needed for construction, the hardened concrete and materials used to construct the area will be removed and properly disposed of.

Washing will only be allowed in designated areas, away from surface water and stormwater inlets.

SECTION 6: INSPECTION, MAINTENANCE, AND CORRECTIVE ACTION

6.1 Inspection Personnel and Procedures

Personnel Responsible for Inspections Personnel responsible for conducting inspections will be “qualified inspection personnel”.

Qualified inspector personnel means “a person knowledgeable in the principles and practice of erosion and sediment controls, who possesses the skills to assess all conditions at the construction site that could impact storm water quality and to assess the effectiveness of any sediment and erosion control measures selected to control the quality of storm water discharges from the construction activity”. Qualified inspectors are named in Section 1 under Stormwater Team.

Inspections Requirements The permittee shall assign “qualified inspection personnel” to conduct inspections to ensure that the control practices are functional and to evaluate whether the SWP3 is adequate and properly implemented in accordance with the Sequence of Construction or whether additional control measures are required.

Disturbed areas and areas used for storage of materials that are exposed to precipitation shall be inspected for evidence of or the potential for pollutants entering the drainage system. Erosion and sediment control measures identified in the SWP3 shall be observed to ensure that those are operating correctly. Discharge locations shall be inspected to ascertain whether erosion and sediment control measures are effective in preventing significant impacts to the receiving waters.

Locations where vehicles enter or exit the site shall be inspected for evidence of off-site vehicle tracking.

Inspection Schedule At a minimum, all controls on the site shall be inspected:

• after any storm event greater than one-half inch of rain per 24-hour period by the end of the next calendar day, excluding weekends and holidays unless work is scheduled; and

• once every seven calendar days.

The inspection frequency may be reduced to at least once every month for dormant sites if:

• the entire site is temporarily stabilized or

• runoff is unlikely due to weather conditions for extended periods of time (e.g., site is covered with snow, ice, or the ground is frozen).

The beginning and ending dates of any reduced inspection frequency shall be documented in the SWP3. Once a definable area has achieved final stabilization, the area may be marked on the SWP3 and no further inspection requirements shall apply to that portion of the site.

Inspection Reporting Following each inspection, a checklist must be completed and signed by the qualified inspection personnel representative. At a minimum, the inspection report shall include:

1. the inspection date;

2. names, titles, and qualifications of personnel making the inspection;

EPA SWP3 Template, Version 2.1 26

3. weather information for the period since the last inspection (or since commencement of construction activity if the first inspection) including a best estimate of the beginning of each storm event, duration of each storm event, approximate amount of rainfall for each storm event (in inches), and whether any discharges occurred;

4. weather information and a description of any discharges occurring at the time of the inspection;

5. location(s) of discharges of sediment or other pollutants from the site;

6. location(s) of BMPs that need to be maintained;

7. location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location;

8. location(s) where additional BMPs are needed…
