Receiving waters and wetlands:

NAVSTANPT is located within the Upper East Passage Watershed and Lower East Passage Watershed of Rhode Island. Each of these watersheds drain to Narragansett Bay, which then drains towards the south to the Atlantic Ocean. Outfalls associated with NAVSTANPT drain directly to Coasters Harbor, Coddington Cove, Brenton Cove, and East Passage.

Based on the National Wetlands Inventory, there are several wetlands located within the installation boundaries that receive runoff from NAVSTANPT. At the northern end of Midway there is a freshwater emergent wetland approximately 3.4 acres in size. East of NUWC there is a freshwater forested/shrub wetland approximately 7.1 acres in size that drains to a freshwater pond approximately 2.2 acres. East Coddington Cove and west of Building 47CC, there is a freshwater emergent wetland approximately 4.1 acres in size. Along the coast west of the installation and around a small section Coasters Harbor Island there are estuarine and marine wetlands are a total approximately 61.1 acres in size.

Narragansett Bay is an impaired water for the pollutant Enterococcus and affects only certain areas of the coast along NSN. Discharges are not subject to effluent guidelines.

1. Introduction This section of the report provides the project background and site overview;

authorization, scope, and purpose; report content; an overview of regulations; summary of activities at Naval Station Newport; and a summary of receiving waters and wetlands.

1.1 Scope

This report presents the updated Stormwater Management Plan (SWMP) which is required by the Rhode Island Pollution Discharge Elimination System (RIPDES) Multi Sector General Permit {MSGP), RIPDES Storm Water Discharge Associated with Industrial Activity, Permit Number RIR50P018, effective September 1, 2024.

The primary purpose of a SWMP is to identify the regulated industrial activities at a site and describe the best management practices (BMPs) to be implemented by the industrial facility operator to prevent storm water pollution.

1.2 Site History

Naval Station (NS) Newport has an extensive naval history dating back to the Revolutionary War when it was used as a naval port by the British and later the French Navies. It was not until the late 19th century that the United States Navy officially began developing the eastern shores of Narragansett Bay and western portion of Aquidneck Island. The Navy acquired Coasters Harbor Island from the state of Rhode Island in 1881 and on 4 June 1883, commissioned the Navy's first Recruit Training Station. The Naval War College was founded on the island on 6 October 1884. The Naval Hospital was constructed around 1913 on Aquidneck Island, adjacent to Coasters Harbor Island.

When the United States entered World War I in 1917, thousands of recruits were sent to the Newport Recruit Training Station, and the Navy subsequently acquired Coddington Point to accommodate the massive influx of personnel, estimated to be over 75,000. In the 1940's, during World War 11, the base underwent significant growth. Additional property in Coddington Cove was acquired and developed as a Supply Station, and a fuel supply depot was constructed at Melville. During this time, several other Navy support stations, including a Naval Air Station (NAS) at Quonset Point, were established along Narragansett Bay, making the Newport Naval Complex one of the largest Naval installations at the time.

After World War 11, many of the surrounding commands were deactivated, and the Newport Naval Complex was consolidated under a single command, United States Naval Base Newport in 1946. By 1952, the Naval Recruit Training Station at Newport was disestablished, but the Fleet Training Center and Naval School Command continued to provide specialized training to fleet personnel, and the Officer Candidate School (OCS) opened in 1951. Throughout the next 50 years, the Newport Naval Complex saw a significant drawdown, with the closure of the Naval Air Station at Quonset Point, transfer of commands and fleets to other bases, and a general cutback on personnel and activities.

On 1 October 1998, Naval Station Newport was officially commissioned as the primary host command, taking over all base operating support responsibilities.

Since the 2005 Base Realignment and Closure (BRAC) Commission Study, NS Newport has again seen a period of regrowth as it was identified to host additional personnel and tenant commands. As a result of the 2005 BRAC Commission Study, NS Newport gained over 500 billets, the Naval Supply Corps School, Army and Navy Reserve units, Center for Service Support, and the United States Marine Corps Aviation Logistics School.

1.3 Site Overview

The property of NS Newport currently consists of several parcels on the west side of Aquidneck Island within the cities of Newport, Middletown, and Portsmouth, Rhode Island. The base includes more than 1,500 acres with a total of 1,028 buildings and employs approximately 5,800 personnel at 50 commands with an additional 17,000 students annually passing through one of the many schools on base.

Today, NS Newport is the Navy's premier site for training officers, officer candidates, senior enlisted personnel, and midshipman candidates, as well as conducting advanced undersea warfare and development systems. The base is home to 50 Navy, Marine Corps, Coast Guard, and Army Reserve commands. Activities that are supported within the Newport Naval Complex include, but are not limited to: Officer Training Command Newport (OTCN), Surface Warfare Officers School (SWOS), the Naval Justice School, Naval Undersea Warfare Center (NUWC), the Naval War College (NWC), and Naval Health Clinic New England (NHCNE).

The mission of NS Newport is to fulfill the diverse requirements of its tenant commands by providing the facilities and infrastructure that are essential to their optimum performance. NS Newport will ensure that the highest standards of the Navy are incorporated into its efforts; that all tenant commands will benefit from its continuous improvement; and that all hands will work together to earn and maintain its reputation as the Navy's world-class Center of Learning Excellence.

Base Flood Elevation Portions of Naval Station Newport are located in a flood zone. For the purposes of this SWMP and the industrial areas that it covers, the entire building W36 is located in Flood Zone AE Elevation 13. Flood Zone AE Elevation 14 directly abuts the western side of building 47.

Figure 1-1 is a general map of NS Newport.

1.5 Overview of Regulations

Federal Regulations

Section 402(p) of the Clean Water Act (CWA) requires operators of "discharges associated with industrial activity" obtain a National Pollutant Discharge Elimination System (NP0ES) permit. In 1990, the US Environmental Protection Agency (EPA) developed the permitting regulations under the Phase I NP0ES to control storm water discharges associated with the following eleven categories of industrial activity as identified in 40 CFR 122.26(b)(14)(i)-(xi):

Category One (i): Facilities subject to federal storm water effluent discharge standards at 40 CFR Parts 405-471

Category Two (ii): Heavy manufacturing (e.g., paper mills, chemical plants, petroleum refineries, steel mills and foundries)

Category Three (iii): Coal and mineral mining and oil and gas exploration and processing

Category Four (iv): Hazardous waste treatment, storage, and disposal facilities

Category Five (v): Landfills, land application sites, and open dumps with industrial wastes

Category Six (vi): Metal scrapyards, salvage yards, automobile junkyards, and battery reclaimers

Category Seven (vii): Steam electric power generating plants

Category Eight (viii): Transportation facilities that have vehicle maintenance, equipment cleaning, or airport deicing operations

Category Nine (ix): Treatment works treating domestic sewage with a design flow of 1 million gallons a day or more

Category Ten (x): Construction sites that disturb 5 acres or more (permitted separately)

Category Eleven (xi): Light manufacturing (e.g., food processing, printing and publishing, electronic and other electrical equipment manufacturing, public warehousing and storage)

Activities regulated by the RIDEM Industrial Storm Water Permit are also categorized by industrial sector. These sectors group similar facilities by nature of industrial activity, type of materials handled, and material management practices employed and are for the most part based on the facility's Standard Industrial Classification (SIC) Code.

Sector A: Timber Products Facilities

Sector B: Paper and Allied Products Manufacturing Facilities

Sector C: Chemical and Allied Products Manufacturing and Refining

Sector D: Asphalt Paving and Roofing Materials and Manufacturers and Lubricant Manufacturers

Sector E: Glass, Clay, Cement, Concrete, and Gypsum Product Manufacturing Facilities

Sector AC: Electronic and Electrical Equipment and Components, Photographic, and Optical Goods Manufacturing Facilities

Most industrial storm water discharges are covered under general permits, as opposed to individual permits, although States and EPA issue individual permits to some facilities based on site-specific or industry-specific concerns. General permits are used primarily because they avoid the need to issue multiple permits, and instead only require a single permit to cover a large number of industrial facilities performing similar types of activities. To be covered under a general permit, an eligible operator of an industry must read the general permit, develop a SWMP, comply with any special eligibility provisions, and submit a notice of intent (NOI) or permit application to the permitting authority.

Rhode Island Regulations

The Rhode Island Department of Environmental Management (RIDEM) has been the delegated authority to implement the NPDES program in Rhode Island (referred to as RIPDES) since 1984. In 1993, the RIDEM's Office of Water Resources (OWR) developed a statewide general industrial permit which was re issued in 1998 for an additional five years. In January of 2003, the draft general permit was reissued again for a one-year effective period to allow the OWR to determine if any significant modifications of the permit were required. RIDEM finalized and signed the Multi-Sector General Permit for Storm Water Discharge Associated with Industrial Activities on March 30th, 2006 which became effective on May 1st, 2006.

The permit was revised and became effective August 15, 2013 and has an expiration date of August 14, 2018. This permit was revised and became effective May 3, 2019 and had an expiration date of May 2, 2024. The most recent permit was effective September 1, 2024 with an expiration date of August 31, 2029. Refer to Appendix A for a copy of the permit.

NAVSTANPT was initially authorized to discharge under the general permit issued in March 1998. Since that time, NAVSTANPT has received authorizations to discharge under the re-issued permits and is currently covered under the Multi Sector General Permit for Storm Water Associated with Industrial Activity (RIR50P018). The industrial storm water permit requires that a facility with regulated industrial activities develop a SWMP. The specific requirements listed in Part V of the permit are listed below along with the corresponding section in this document that addresses the requirement.

1. 6 Summary of Activities at Naval Station Newport As part of the SWMP update, a comprehensive windshield survey was completed of the entire installation to identify activities onsite with the potential for storm water pollution. The windshield survey served as a screening mechanism. Then a more detailed site investigation was completed for sites suspected of being regulated under the industrial storm water permit requirements and/or the potential to contribute to storm water pollution.

During the field work for the SWMP update, attention was paid to the industrial activities listed in the existing SWMP as well as activities included in previous versions of the SWMP. Each of these areas was visited, observed, and documented via written notes and photographs.

A list of the sites visited along with their designated SIC code and associated description is summarized in Table 1-1. The table also includes information on whether the site is regulated under the industrial storm water permit, the municipal storm water permit, or not applicable to either storm water permit. Note that this table was based on the field visit, the previous SWMP, and communication with a representative of NAVSTANPT Environmental Division, a representative from Naval Facilities Engineering Command (NAVFAC) Mid-Atlantic, and points of contact at the sites of interest. Site Compliance Evaluation (SCE) inspection forms were conducted and reported in accordance with the previous permit. Inspection reports for the visited sites that were determined to not be regulated industrial activities (including narrative, site maps, and photolog) were provided to NAVSTANPT under separate cover.

A total of three sites were determined to be associated with industrial activity:

❖ Building 47CC: Shipping and Receiving Warehouse o Classified as SIC Code 4225 (General Warehousing and Storage):

Establishments primarily engaged in the warehousing and storage of a general line of goods.

o Sector P - Land Transportation and Warehousing ❖ Building W-36CP: Reserves Vehicle and Boat Maintenance Storage Facility o Classified as SIC Code 4499 - Water Transportation Serviced, Not Elsewhere Classified: Establishments primarily engaged in furnishing miscellaneous services incidental to water transportation, not elsewhere classified.

1. 7 Receiving Waters and Wetlands at Naval Station Newport NAVSTANPT is located within the Upper East Passage Watershed and Lower East Passage Watershed of Rhode Island. Each of these watersheds drain to Narragansett Bay, which then drains towards the south to the Atlantic Ocean.

Outfalls associated with NAVSTANPT drain directly to Coasters Harbor, Coddington Cove, Brenton Cove, and East Passage.

Based on the National Wetlands Inventory, there are several wetlands located within the installation boundaries that receive runoff from NAVSTANPT. At the northern end of Midway there is a freshwater emergent wetland approximately 3.4 acres in size. East of NUWC there is a freshwater forested/shrub wetland approximately 7.1 acres in size that drains to a freshwater pond approximately 2.2 acres. East Coddington Cove and west of Building 47CC, there is a freshwater emergent wetland approximately 4.1 acres in size. Along the coast west of the installation and around a small section Coasters Harbor Island there are estuarine and marine wetlands are a total approximately 61.1 acres in size.

2. Potential Pollutant Sources This section describes regulated industrial sites at NAVSTANPT, spills and leaks in the past five years, allowable non-storm water discharges at the site, and runoff coefficients developed for the drainage areas of the regulated industrial activities.

2.1 Regulated Industrial Sites

Three sites at NAVSTANPT are associated with regulated industrial activity:

❖ Building 47CC: Shipping and Receiving Warehouse ❖ Building W-36CP: Reserves Vehicle and Boat Maintenance Storage Facility

The sections below present a description of the regulated sites, associated activities and pollutants, method of on-site disposal, flow direction, salt storage, sampling data, existing BMPs, and recommended BMPs. Refer to Section 3 for additional information on BMPs.

2. 1.1 Building 4 7CC: Shipping and Receiving Warehouse Site Description: Building 47CC is located in Coddington Cove and is the primary shipping and receiving warehouse for NAVSTANPT and tenants. The building's activities are classified as SIC Code 4225 (General Warehousing and Storage) and Sector P (Land Transportation and Warehousing).

A site map of Building 47CC is included in Appendix F, showing the building and proximate parking areas using aerial imagery. Appendix F also includes a photolog of pictures taken during the field work.

The warehouse stores supplies, equipment, and materials for buildings in NAVSTANPT that are not mailed or delivered directly to individual facilities. Naval Undersea Warfare Center (NUWC) is the primary organization served by the warehouse, although occasionally the warehouse receives and transfers material for other tenant commands including the Naval Warfare Command, the Surface Warfare Officer School Command, the Naval Ambulatory Care Center, the Naval Justice School, the Officer Training Command, the Naval Academy Prep School, the Command Leadership School, the Senior Enlisted Academy, the Surface Warfare Officer's School Division Officer Course, Service Station, Post Office, Uniform Shop, Supply operations, and Public Works.

Activities in the Area: Specific activities at the site include:

❖ Loading and unloading of raw materials using forklifts and pallet jacks at eight covered and eleven uncovered loading bays. The covered loading bays are located on the western side of the building and the uncovered loading bays are located on the eastern side of the building.

❖ Onsite storing of recycled materials, including mixed wire, scrap aluminum, miscellaneous metals, and pipes. Dumpsters are located both on the western and eastern sides of the building. Miscellaneous metals and pipes are located primarily around the southern half of the building, both on the eastern and western sides of the building.

Some flammable liquids are stored and managed by hazardous material (HAZMAT) certified technicians at this building. HAZMAT materials are only loaded and off loaded at the covered loading bays. Loading bays on the eastern side of the building are inactive, and therefore only the western side of the building involves activities with the potential for storm water pollution.

There are also flammable materials cabinets at the western side of the building.

Pollutants: Potential pollutants at this site include:

Raw materials which are loaded and unloaded at the loading bays. Since staff at the warehouse are trained on loading and unloading procedures and appropriate spill response, the potential for storm water pollution from loading and unloading activities is classified as low.

Hazardous materials which are loaded and unloaded at covered bays. Staff are also trained on proper loading and unloading procedures, as well as spill response. Hazardous materials are stored under the building roof and either on palettes or in flammable materials cabinets. The potential for storm water pollution is classified as low. However, it should be noted that these bays are located very close to storm drains (refer to the site map in Appendix F) and because of this, there is risk of spilled materials entering the storm drain system. Additionally, no floor drains in the building are connected to the storm drain system. The only floor drains in the building are in bathrooms, which are connected to the sanitary system.

Recycled materials (mixed wire and scrap aluminum) and miscellaneous metals stored outside are classified as low potential for storm water pollution.

Leaks from stored equipment and vehicles. However, there are no fueling stations; vehicle and equipment maintenance areas; locomotive sanding activities or processing areas onsite. So, this is classified as low potential for storm water pollution.

Per-and Polyfluoroalkyl Substances (PFAS) Storage and Release:

Per- and Polyfluoroalkyl Substances (PFAS) are manufactured chemicals that are long lasting and persistent in the environment. They have been widely used since the 1940s and are found in many different consumer, commercial, and industrial products. PFAS constituents were present in aqueous film-forming foam (AFFF) stored and potentially used and/or disposed at Naval Station Newport. As a result of a five year review, Naval Station Newport conducted an installation-wide assessment of PFAS under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) program in 2018.

Numerous areas were identified where AFFF containing PFAS were stored and potentially used and/or disposed. One of these areas is Building 47. An independent interview conducted by the USEPA with a former Fire Chief disclosed that there was a fire training area in the parking lot adjacent to Building 47. In 2020, a site investigation was conducted in the area and groundwater samples were collected. Based on the PFAS concentrations observed in groundwater, there is a potential for a release of PFAS-containing firefighting foam to have occurred in the area. Based on the results, the Navy has determined that further investigation is needed in this area.

It is impossible to have a list of all materials utilized at the facility which contain PFAS (especially as some materials generically have not been tested); however, it is reasonable to presume that many materials utilized at the Naval Station contain some levels of PFAS.

The following are examples of items which may be or have been utilized at Naval Station which may contain PFAS:

• Building Materials such as architectural membranes, cement additives, cable & wire insulation;

• Batteries;

• Clothing;

• Food packaging;

• Textiles and/or surface treatments (such as sails, seat covers, etc.);

• Leather and surface treatments;

• Weather resistant paint, varnishes, sealants, solvents and adhesives, waxes, rubber, and gelcoat;

• Aerosol propellants;

• Wood particle board and/or coatings;

• Fuel lines, electronic components, engine components/coatings;

• Firefighting foam and flame-retardant materials;

• Glass (for water repellant);

• Paper and cardboard

When possible, PFAS-free materials will be used at the facility and will replace materials which contain PFAS or are suspected to contain PFAS .

Good operating and housekeeping practices will also be followed such as:

1. Chemical inventory regularly maintained.

2. Safe chemical storage, such as secondary containment and placement away from floor drains that lead storm drains.

3. Replacement of contaminated equipment, if it is a source of legacy PFAS discharges.

4. Containing or reusing contaminated equipment in between uses, rather than rinse and disposal.

5. Containing contaminated rinse water of equipment, employee handwashing, or protective gear.

6. Proper operation and maintenance of equipment to avoid malfunction and accidental discharge.

7. Emergency response plan that addresses spill containment and cleanup of PFAS.

8. Employee education and training on good housekeeping, operations, and emergency response.

9. Proper management/disposal of legacy PFAS chemicals.

Examples of improvements the installation can conduct to minimize stormwater impacts from PFAS include:

• Keeping the dumpsters closed and locking the cover (if not already conducted) to prevent opening in the event of a hurricane or flood.

•Continuing to conduct site investigations of the area to determine the extent of the contamination.

Method of On-Site Storage or Disposal: Staff at this building utilize solid waste dumpsters for storage and disposal of waste.

Flow Direction: The site map in Appendix F illustrates the direction of storm water flow is in an overall westerly direction toward storm drain inlets. These flow directions were based on analysis of the topographic elevations within the ArcGIS data.

2.1.2 Building W-36CP: Navy Reserves

Maintenance Facility and Motor Pool

Site Description: Building W-36CP is located in Coddington Point and is a maintenance facility and motor pool for the Navy Reserves Coastal Riverine Squadron Eight. The building's activities are classified as SIC Code 4499 (Water Transportation Services Not Elsewhere Classified) and Sector Q (Water Transportation Facilities).

A site map of Building W-36CP is included in Appendix F, showing the building and proximate parking areas using aerial imagery. Appendix F also includes photolog of pictures taken during the field work.

Activities in the Area: Specific activities at the building include:

Repair and maintenance of boats used for water transportation.

Maintenance activities typically include various engine maintenance activities. Hull work (sanding and painting) is rarely conducted, but small scale repairs may be conducted on site. Boat repair and maintenance are typically conducted indoors.

Operations level maintenance of the vehicles and equipment on site.

Vehicles and fueled equipment maintained include light and medium tactical vehicles, generators, water buffalos, and lights.

Materials such as anti-freeze, used oil and filters, lead-acid batteries, paints, and gasoline are properly disposed of or recycled by certified personnel or private contractors. No maintenance activities or storage or disposal of wastes are performed outdoors.

An AST is located at the northern side of the building.

Fueled and non-fueled vehicles and equipment, and conex boxes are located in the parking area south of the building.

Pollutants: The potential pollutants at this site include:

Gasoline, flammables, acids/bases, oxidizers, oils, paints, and toxins for conducting indoor activities. These materials are stored indoors. Since staff are trained on appropriate spill response and disposal procedures, the potential for storm water pollution is classified as low.

The transfer of fuel/heating oil to the AST. Since the tank includes secondary containment, the potential for storm water pollution is classified as low.

Leaks from stored equipment and vehicles. There are no fueling stations and vehicles and equipment are maintained indoors, therefore this is classified as low potential for storm water pollution.

Per-and Polyfluoroalkyl Substances (PFAS) Storage and Release:

Per- and Polyfluoroalkyl Substances (PFAS) are manufactured chemicals that are long lasting and persistent in the environment. They have been widely used since the 1940s and are found in many different consumer, commercial, and industrial products. PFAS constituents were present in aqueous film-forming foam (AFFF) stored and potentially used and/or disposed at Naval Station Newport.

It is impossible to have a list of all materials utilized at the installation which contain PFAS (especially as some materials generically have not been tested); however, it is reasonable to presume that many materials utilized at the Naval Station contain some levels of PFAS. Naval Station Newport conducted an installation-wide assessment of PFAS under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) program in 2018. Numerous areas were identified where AFFF containing PFAS were stored and potentially used and/or disposed. Building W36CP was not identified as having historical use of PFAS.

The following are examples of items which may be or have been utilized at Naval Station which may contain PFAS:

• Building Materials such as architectural membranes, cement additives, cable & wire insulation;

• Batteries;

• Clothing;

• Food packaging;

• Textiles and/or surface treatments (such as sails, seat covers, etc.);

• Leather and surface treatments;

• Weather resistant paint, varnishes, sealants, solvents and adhesives, waxes, rubber, and gelcoat;

• Aerosol propellants;

• Wood particle board and/or coatings;

• Fuel lines, electronic components, engine components/coatings;

• Firefighting foam and flame-retardant materials;

• Glass (for water repellant);

• Paper and cardboard

When possible, PFAS-free materials will be used at the facility and will replace materials which contain PFAS or are suspected to contain PFAS .

Good operating and housekeeping practices will also be followed such as:

1. Chemical inventory regularly maintained.

2. Safe chemical storage, such as secondary containment and placement away from floor drains that lead storm drains.

3. Replacement of contaminated equipment, if it is a source of legacy PFAS discharges.

4. Containing or reusing contaminated equipment in between uses, rather than rinse and disposal.

5. Containing contaminated rinse water of equipment, employee handwashing, or protective gear.

6. Proper operation and maintenance of equipment to avoid malfunction and accidental discharge.

7. Emergency response plan that addresses spill containment and cleanup of PFAS.

8. Employee education and training on good housekeeping, operations, and emergency response.

9. Proper management/disposal of legacy PFAS chemicals.

Examples of improvements the installation can conduct to minimize stormwater impacts from PFAS include:

• Keeping the dumpsters closed and locking the cover (if not already conducted) to prevent opening in the event of a hurricane or flood.

•Continuing to conduct site investigations of the area to determine the extent of the contamination.

Method of On-Site Storage or Disposal: Staff at this building utilize solid waste dumpsters for storage and disposal of waste. Bilge water is collected indoors and directed to the sanitary system.

Flow Direction: The site map in Appendix F illustrates the direction of storm water flow is in an overall westerly direction toward storm drain inlets. These flow directions were based on analysis of the topographic elevations within the ArcGIS data.

Salt Storage: No salt is stored at Building W-36CP.

Sampling Data: Existing storm water discharge sampling not required according to the previous SWMP. Section 4 outlines sampling required for this updated SWMP.

Existing BMPs (to be maintained): Existing BMPs are listed below and can be found in Appendix F.

Existing Structural Controls:

The AST is located within secon226d226ary containment.

Existing Non-Structural Controls

❖ Hazardous materials are stored indoors or under cover.

❖ Spill kits are adequately stocked onsite.

During the SWMP field investigation and the comprehensive SCE, no unallowable discharges were observed at any regulated sites with industrial activity. Likewise, no signs of non-storm water discharges were evident from any of the outfalls associated with industrial activity.

NAVSTANPT's RIPDES General Permit for Storm Water Discharges from small Municipal Separate Storm Sewer System {MS4s) and from Industrial Activity at Eligible Facilities Operated by Regulated Small MS4s (RIR040004) includes requirements for the monitoring of outfalls to assess the illicit discharge detection and elimination minimum control measure. Refer to NAVSTANPT's Municipal Storm Water Program Plan for more information.

NAVSTANPT does not authorize any non-storm water discharges from any of its tenants. They maintain an active program that inspects, monitors, and cleans all applicable storm water infrastructure on an annual basis. This program also involves detection and elimination of illicit discharges. Logs of inspections from the past five years were reviewed and no illicit discharges or sources of pollution were found at any sites with regulated industrial activity.

2.2 Runoff Coefficients

The three sites with associated industrial activity drain to three outfalls:

❖ Outfall 7-137 (Building 47CC) ❖ Outfall 4-37A (Buildings W-34CP and W-36CP) ❖ Outfall 4-54A (Building W-34CP) (2019 activities ceased at this location. Building 13 (Outfall 7-96A) is storage for boats but activities have not started as of 12/2022).

Runoff coefficients have been calculated for each outfall drainage basin. Land uses in the drainage area includes:

❖ Asphalt roadway, parking, and roofs (runoff coefficient of 0.95) ❖ Industrial (runoff coefficient of 0.70) ❖ Commercial (runoff coefficient of 0.60) ❖ Residential (runoff coefficient of 0.50) ❖ Pasture (runoff coefficient of 0.20) ❖ Forest (runoff coefficient of 0.15)

Outfall 7-137 has a weighted average runoff coefficient of 0.59. The area east of the Army Regional Reserve Center is considered residential, along with a small section in the very most southwestern corner of the drainage area. For calculating runoff, the majority of the area east of Building 47CC and west of the Army Regional Reserve Center are considered industrial. Grassy areas throughout the drainage area, north of Building A63CC, and west of Building 47CC are all considered pasture. There is a small patch of forest west of Building 47CC. Pavement and roofing exist throughout the drainage area. There are no commercial areas with the Outfall 7-137 drainage area.

Outfall 4-37A has a weighted average runoff coefficient of 0.75. For calculating runoff, the area around Buildings W-34CP and W-36CP are considered industrial.

The grassy areas north of Building W-36CP and south of Buildings 360 and 1288 are considered pasture. There are no commercial, forest, or residential areas within the Outfall 4-37A drainage area. However, pavement and roofing exist throughout the drainage area.

Outfall 4-54A (2019 activities ceased at this location. Building 13 (Outfall 7-96A) is storage for boats but activities have not started as of 12/2022) has a weighted average runoff coefficient of 0.77. The grassy area south of Building 355 is considered pasture. The areas adjacent to Buildings 344, 345, 346, 347, 1288, and 360 are all considered commercial. There are no commercial, forest, or residential areas within the Outfall 4-54A drainage area. However, pavement androofing exist throughout the drainage area.

Figure 2-1 is a site map of Outfall 7-137 and the contributing drainage area, and it shows the breakdown of contributing land use areas.

Figure 2-2 is a site map of Outfalls 4-37A and 4-54A, their contributing drainage areas, and includes a breakdown of contributing land uses for each outfall.

3.0 Storm Water Control Measures

3.1 Pollution Prevention Team

The pollution prevention team is responsible for the SWMP including implementation and maintenance of storm water control measures, taking corrective action when necessary to address compliance issues or improve BMP performance, and updating the SWMP to reflect changes made to the site conditions or control measures. The team is comprised of the primary contact for the SWMP for the entire installation and the various points of contact for the regulated industrial activities at NAVSTANPT.

The primary contact for the SWMP is responsible for overseeing facility activities for permit compliance and ensuring that inspections and monitoring activities are completed. In addition, the primary contact for the SWMP is the main point of contact for any regulatory inspections that may be completed by RIDEM or EPA.

Table 3-1 below lists the Pollution Prevent Team members for the sites with regulated industrial activities.

3.2 Non-Structural BMPs

The Environmental Department at NAVSTA Newport has implemented an environmental management program that includes many non-structural BMPs.

These are policies and procedures that prevent or minimize the potential of storm water pollution, and they typically include non-physical elements. Non-structural BMPs at NAVSTANPT include:

❖ Minimizing Impacts from Major Storm Events ❖ Good Housekeeping ❖ . Minimizing Potential Exposure

❖ Preventative Maintenance ❖ Spill Prevention and Response Procedures ❖ Routine Facility Inspections ❖ Personnel Training
