MDE Industrial SWPPP Template, February 7, 2023 i

Industrial SWPPP Template

Introduction

To help you develop a Stormwater Pollution Prevention Plan (SWPPP) that is consistent with industrial stormwater permits, MDE recommends using this template, which a modified version of the one that the U.S Environmental Protection Agency (EPA) has created. Use of the Template will help ensure that your SWPPP addresses necessary elements required in industrial stormwater permits.

Before completing the Template, make sure you read and understand the requirements in the General Permit (20SW, 15MM, 16MA, etc). A copy of all the General Permits are available on our website, as is a guide for creating a SWPPP. You may also call us at 410-537-3323, if you have questions about this process.

Using the Industrial SWPPP Template

Tips for completing the Template:

• This Template is designed for use by all facilities eligible for coverage. The Template is NOT tailored to your individual industrial sector. Depending on which industrial sector you fall under (see Appendix A of the General Permit 20-SW, 15-MM, 16-MA, etc) and on where your facility is located, you will need to address additional SWPPP requirements outlined in the permit SWPPP requirements in the permit or Appendix D and/or Chesapeake Bay Restoration Requirements of the permit.

• Complete a SWPPP before submitting your Notice of Intent (NOI) for permit coverage.

• Each section includes “instructions” and space for your facility’s specific information.

You should read the instructions for each section before you complete that section.

• The Template was developed in Microsoft Word so that you can easily add tables and additional text. Some sections may require only a brief description while others may require several pages of explanation.

• To make it easier to complete, the Template generally uses blue text where the operator is expected to enter information.

MDE recognizes that while every effort has been made to ensure the accuracy of all instructions and guidance contained in the Template, the actual obligations of regulated industrial facilities are determined by the relevant provisions of the permit, not by the Template. In the event of a conflict between the Template and any corresponding provision of the General Permit, the permit controls. MDE welcomes comments on the Template at any time and will consider those comments in any future revision of this document.

− Note: You will be asked additional questions concerning salt storage in Section 3.7 of this SWPPP template, below.

2023 11

2.5. Visual Monitoring Summary

Grit/paint chips/dust accumulation observed throughout the industrial area where hydroblasting, grit, and slurry blasting occur appears to be the most consistent issue found during visual monitoring inspections.

2.6. PFAS and PCB Source Identification

Potential current PFAS sources at the Yard are AFFF concentrate. AFFF deluge system is located at Building 20 the Flammable Material Storage Buidling and 90-day hazardous waste accumulation area for the Yard. The system is used to control and extinguish Class B fire consisting of hydrocarbon fuels and flammable liquids. AFFF is stored in two 600-gallon vertical bladder tanks and filled with 413 gallons of 6 percent AFFF concentrate. Building 20 trench and floor drains are connected to a concrete vault designed to hold AFFF/water when the deluge system discharges. AFFF/water generated in the concrete vault is removed and disposed of in accordance with regulations.

Firehouse located at Building 79 handles fires related to ship repair, fuels in storage, and structural fires at the Yard. Since 2023 the Firehouse no longer uses or stores AFFF in fire trucks or at Building 79. The Yard temporarily stores vessels on the shiplift for maintenance and repairs that may contain AFFF/water in their fire suppression systems.

Historic sources of PCBs were transformer substations containing PCB dielectric fluids. The dielectric fluids were removed approximately 30 years ago from transformers and switched to alternatives (mineral oil). In 2004 and 2007 environmental investigations involved collecting soil and wipe samples at substations, manholes, and electric poles throughout the Yard for PCBs. A removal action was completed at substation 102 near Building 30 in 2008 which involved a 1-ft excavation of soil. Occasionally PCB industrial waste may come from ships docked at the Yard, this industrial waste is disposed of in accordance with regulations.

Instructions (See General Permit Part III.C.3):

− Summarize what you have observed as potential problems from stormwater during the previous permit term.

Instructions (See General Permit Parts III.C.3.ii, and III.C.3.iii):

− In Section 2.6 of this SWPPP template, you are asked to describe potential sources of per- and polyfluoroalkyl (PFAS) and Polychlorinated Biphenyls (PCBs). See the 20SW permit Part III.C.3.ii for a list of SIC codes that have a higher likelihood of containing PCBs. For please see Part III.C.3.iii for the chemicals we are looking for as well as the following link to the EPA’s PFAS website https://www.epa.gov/pfas/basic-information-pfas for more detailed information. Provide a narrative summary below any potential current or historic uses of PFAS or PCB’s below.

3. STORMWATER Control Measures

3.1. Minimize Exposure

All containerized materials (fuels, paints, solvents, used oil, antifreeze, batteries, etc.) must be stored as to protect them from mixing with stormwater. Best management practices associated with these materials include the following:

• Containers must be clearly marked as to their contents. Wipe down the outside of 55 gallon drums;

• Containers must be kept in secure locations away from storm drains;

• Secondary containment measures for 55 gallon drums and tanks will be kept clean and free of debris;

• Accumulated precipitation within containment structures will be drained in accordance with the

USCG

EMSM, Section B6 – Spill Control and Countermeasure (SPCC) Plan;

• Lead-acid batteries must be stored in an area that is protected from stormwater and is capable of containing any fluid leaks as detailed in USCG EMSM, Section C12– Recycling Lead-Acid Batteries. Store in plastic box or on containment at Building 66 - Garage;

• Spent abrasive materials must be recovered and containerized for offsite disposal;

• Hazardous wastes and hazardous materials will be maintained as outlined in USCG EMSM, Section C2 – Hazardous Materials and Waste Transportation Within the YARD; and, Instructions (See General Permit Parts III.C.4, III.A and III.B.1.b):

− In Sections 3.1 - 3.12 of this SWPPP template, you are asked to describe the stormwater control measures that you have installed at your site to meet each of the permit’s “non-numeric effluent limits” in Part III.B of and in some cases “Chesapeake Bay Restoration Requirements” in Part III.A.

Instructions (see General Permit Part III.B.1.b.):

− Describe any structural controls or practices used to minimize the exposure of industrial activities to rain, snow, snowmelt, and runoff. Describe where the controls or practices are being implemented at your site.

2023 13

• Scrap metals shall be managed in accordance with USCG EMSM, Section C11 – Recycling Scrap Metal.

3.2. Good Housekeeping

Maintaining good general housekeeping practices at the YARD is essential to the prevention of contamination of stormwater. Procedures for managing materials used by the facility that could potentially impact stormwater quality are outlined in the USCG YARD Environmental Management System Manual and in this Plan. However, the management of other miscellaneous materials is necessary to maintain the cleanliness of the general YARD areas. Housekeeping tasks include:

General Maintenance o Perform a general site cleanup to remove miscellaneous trash as needed. Outdoor areas shall be kept free of spills, rusty metal, paint chips, grit, bagged or loose chemicals, oily equipment, oily drums and all potential water pollutants.

o Remove debris for disposal or recycling at regular intervals to prevent overfill of receptacles o Provide trash receptacles at areas throughout the facility, including each pier and on board each vessel being repaired.

o Keep flammable liquids lockers orderly and clean.

o Dispose of hazardous materials properly.

o Wipe up leaks and spills.

• Spent solvent management. Used paint thinner must be added to Paint Slop drums. Do not put used solvent into a used oil container.

• Vessel wastewaters. Sewage connections must be connected to Hotel sewage connections.

Overboard cooling water discharges must have hoses on them to direct the water to a drain (Shiplift Work Area). Used oil and water must be collected in a used oil tank or drum.

Only ballast water that does not have any oil (or any other pollutants) in it can be discharged to the creek (Environmental Branch must be notified prior to discharge. Clean accessible areas of the drydock prior to flooding and final cleanup following removal of the vessel and raising the drydock.

Include procedures for cleaning up oil, grease, or fuel spills occurring on the drydock.

• Spent abrasives management. Blast grit, soft blast, glass beads, walnut shells cannot be left outside. If spent abrasives do escape a booth/machine, they must be swept up prior to the end of the workday. Place spent abrasives in drums or a collection point inside of the building.

Instructions (see General Permit Parts III.C.5. and III.B.1.b.):

Describe any practices you are implementing to keep exposed areas of your site clean. Describe where each practice is being implemented at your site. Include here your schedule for: (1) regular pickup and disposal of waste materials, and (2) routine inspections for leaks and of the condition of drums, tanks, and containers.

MDE Industrial SWPPP Template, February 7, 2023 14

• Painting and Blasting. Keep paint and blast media out of the water. Do not spray paint on windy days (See EMSM Section C5). Use knockdown curtains to contain paint chips from any painting or blasting operations. The containment and treatment of runoff from hydroblasting activities is covered under NPDES Permit MD0067300. When blasting, no visible emissions are allowed.

When necessary, regularly clean stormwater conveyances of deposits of abrasive blasting debris and paint chips.

• Bulk liquid transfers. Stage the drums onboard the vessel on containment decks. Block the scuppers near the drums, so the vessel’s deck will act as a secondary containment if needed.

Absorbent pads, rags, buckets and appropriate PPE must be present before transfer operations begin.

• Fueling vessels. A spill kit must be at the location of transfer. Drip pans or buckets must be placed under connections and tank vents or vessels. All hoses must be continuous with fittings used to connect hoses. The hose and fittings must be visually inspected before each use to ensure good condition. During the transfer, one person must be next to the tank/drum to ensure that the tank is not overfilling.

• Fueling vehicles. No smoking during fueling. If filling a container, place container on the ground. If a fire starts, do not remove the nozzle, back away immediately. Report all spills promptly.

• Vehicle/boat washing. CG owned vehicles can be washed at Bldg 66’s wash area. GSA vehicles can be washed at a commercial car wash. Boats out of water can be washed with detergents at Bldg 66 or Bldg 30. Fresh water wash downs of boats (in water) are allowed using a garden hose or bucket only. The discharge water must be free of contaminates (paint chips and detergents).

Pressure washing is not permitted.

• Material Storage Areas. Store and plainly label all containerized materials (e.g., fuels, paints, solvents, waste oil, antifreeze, batteries) in a protected, secure location away from drains. Minimize the contamination of precipitation or surface runoff from the storage areas.

3.3. Maintenance

Preventive maintenance is conducted to ensure proper operation of all engineered stormwater treatment devices. Oil/water separators and sediment collection units are inspected on a monthly basis as part of the documented visual facility inspection. Conditions identified that could result in equipment failure are documented and repaired within 30 days of the inspection.

Instructions (see General Permit Parts III.C.5 and III.B.1.b.):

− Describe procedures (1) to maintain industrial equipment so that spills/leaks are avoided, and (2) to maintain any of your site’s control measures in effective operating condition. Include the schedule you will follow for such maintenance activities. Describe where each applicable procedure is being implemented at the site.

2023 15

Temporary sediment collection systems designed to capture debris resulting from blasting and paintingactivities are subjected to daily undocumented visual inspections and quarterly documented inspections to ensure the systems are adequate to serve the intended purpose.

The YARD is investing the use of cartridge filters in storm drains several locations on the shiplift platform.

Depending on the effectiveness of these filters, their use may be expanded to additional areas on the

YARD.

Industrial Equipment Maintenance: monthly SPCC tank inspections and Yellow Gear Maintenance

3.4. Spill Prevention and Response

The YARD has prepared a Spill Prevention, Control and Countermeasure (SPCC) plan and Facility Response Plan (FRP) in accordance with 40 CFR 112. The SPCC plan outlines measures for the containment and mitigation of a potential discharge of petroleum/oils that could adversely impact the environment. The SPCC Plan is incorporated into this SWPPP by USCG EMSM, Section B6– Spill Control and Countermeasure (SPCC) Plan.

Specific BMPs to prevent spills and stormwater contamination include:

• Keep all oils on secondary containment

• Maintain and operate equipment properly

• Identify potential spill areas and drainage routes

Instructions (see General Permit Parts III.C.5. and III.B.1.b.):

− Describe any structural controls or procedures used to minimize the potential for leaks, spills, and other releases. You must implement the following at a minimum:

▪ Procedures for plainly labeling containers (e.g., “Used Oil,” “Spent Solvents,” “Fertilizers and Pesticides,” etc.) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur;

▪ Preventative measures such as barriers between material storage and traffic areas, secondary containment provisions, and procedures for material storage and handling;

▪ Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other releases; and

▪ Procedures for notification of appropriate facility personnel, emergency response agencies, and regulatory agencies.

Describe where each control is to be located or where applicable procedures will be implemented.

− Note: Some facilities may be required to develop a Spill Prevention Control and Countermeasure (SPCC) plan under a separate regulatory program (40 CFR 112). If you are required to develop an SPCC plan, or you already have one, you should include references to the relevant requirements from your plan.

MDE Industrial SWPPP Template, February 7, 2023 16

• Implement spill response procedures. When using stay-dry to absorb a spill, the stay-dry must be swept up. Do not leave the stay-dry on the ground as it will wash into the storm drain.

• Report all spills to x3000 or 410-636-3993

3.5. Erosion and Sediment Controls

The general topography of the facility is relatively flat with a gentle slope towards Curtis Creek or Arundel Cove in most locations. A portion of the facility surface is paved, with unpaved areas being covered by gravel or grass and other vegetation. All disturbed soils or soil stockpiles resulting from earthmoving activities at the facility will be stabilized with vegetation or an impermeable cover (i.e. plastic) in accordance with the State of Maryland sediment and erosion control procedures.

All construction activities that take place at the YARD must be conducted in accordance with the measures outlined for the permitting and control of erosion and sediment established in COMAR 26.17.01 which requires approval of a Sediment and Erosion Control Plan by the Maryland Department of the Environment for all land clearing, grading or other earth disturbance that involves:

1. Greater than 100 cubic yards of grading; or

2. Greater than 5,000 square feet of grading.

Instructions (see General Permit Part III.B.1.b.):

Describe structural or non-structural controls used at your site to stabilize exposed areas and contain runoff to minimize onsite erosion and potential offsite discharges of sediment. Note: You must at a minimum implement flow velocity dissipation devices at outfalls and discharge channels. Describe the location at your site where each control will be implemented.

3.6. Management of Runoff

Restoration Plan. See attachment G for a copy of the restoration plan and restoration activity schedule from 2017 to 2024.

Oil/Water Separators. The facility maintains engineered stormwater treatment devices to address the potential for fugitive oils or sediment resulting from surface preparation activities. Oil/water separators are installed in three areas at the facility as a means of removing oil that may result from maintenance or cleaning activities. The oil/water separators located adjacent to Building 5 (Outfall 24 and 25) and Building 30 (Outfall1) are subsurface units that are installed to collect drainage from areas where small marine vessel washing and maintenance activities are performed. Additionally, an oil/water separator is installed adjacent to Building 66 (Outfall 16 and 18) to collect rinse water from the equipment/machine maintenance activities performed in this area.

Sediment traps for blast grit. Two sediment trapping devices are maintained in the western portion of the facility to prevent the migration of fugitive blast grit to a stormwater outfall. These units are located across the paved surface of Ridgley Street (Outfall 2) and Gunther Way (Outfall 3) near the intersections with Adams Street in the vicinity of Building 35. Additionally, mobile tankers are utilized for the storage of hydroblast water and residue that is captured during surface preparation activities prior to painting.

Instructions (See General Permit Part III.B.1.b. and III.A.2):

Describe controls used at your site to divert, infiltrate, reuse, contain, or otherwise reduce stormwater runoff.

Describe the location at your site where each control will be implemented.

For facilities required to meet Chesapeake Bay Restoration Requirements, develop a plan by completing all the steps in Part III.A.2 of the permit and document in this section of the SWPPP the results of each step.

Provide a schedule and basis for all options you selected that cannot be implemented within 30 days of registration under this permit.

2023 18

3.7. Salt Storage Piles or Piles Containing Salt

Salt for deicing is stored in a covered enclosure at Building 53 to reduce the potential for stormwater contact. The salt storage area is maintained following loading and unloading activities by shoveling, sweeping or other form of dry clean up to minimize the potential for stormwater contact with spilled or displaced deicing salt.

3.8. Sector-Specific Non-Numeric Effluent Limits

The good housekeeping measures described in Appendix D of the 20-SW are included in Section 3.2 (Good Housekeeping) of this SWPPP.

3.9. Employee Training

The Facility Engineer is the facility designee and is responsible for stormwater discharge prevention, control and response preparedness activities at the facility. Employee training is conducted at the facility in order to teach personnel at all levels of responsibility the components and goals of the Stormwater Pollution Prevention Plan. Topics covered in the training program will be focused on the implementation of the Best Management Practices established for storage, use and disposal of potential pollutants and include the following topics:

• Spill Prevention and Response Procedures;

Instructions (see General Permit Part III.B.1.b.):

If applicable, describe structures at your site that either cover or enclose salt storage piles or piles containing salt, or that prevent the discharge of stormwater from such piles. Also, describe any controls or procedures used to minimize exposure resulting from adding to or removing materials from the pile. Describe the location at your site where each control and/or procedure will be implemented.

Instructions (see General Permit Part III.B.1.b. and Appendix D):

− Describe any controls or procedures that will be used at your site to comply with any sector-specific requirements that apply to you in Appendix D of the General Permit. Describe the location at your site where each control and/or procedure will be implemented.

− Note: Sector-specific effluent limits apply to Sectors A, D, E, F, G, H, I, J, L, M, N, O, P, Q, R, S, T, U, V, X, Y, Z, and AA, AD.

Tenant unit personnel will be responsible for the retention of training records for three years. YARD Tennant Commands and Contractors and customers must be made aware of Best Management Practices for the prevention of stormwater pollution prior to the initiation of work at the facility.

3.10. Non-Stormwater Discharges

• During routine ISO 14001 Audits Environmental Branch personnel investigated the drainage path of floor drains in all of the buildings of the facility to verify no connection to the stormwater drainage system. All floor drain inspections that resulted in a pathway to a stormwater system were sealed to prevent their use.

Instructions (see General Permit Part III.B.1.b.):

Describe how you eliminated any unauthorized non-stormwater discharges at your site. The unauthorized non-stormwater discharges include any non-stormwater discharges that are not specifically identified in Part 1.1.3 of the General Permit. Note: If this section is already addressed by your documentation for Section 2.3 of the SWPPP template, you can simply include a cross-reference to that section of your SWPPP.

2023 20

• Investigated the drainage path of outdoor stormwater conveyance system to verify the outfall of each of the stormwater catch basins, a stormwater system drawing exists.

• In 2008, the YARD sealed floor drains in Building 15 that drained to Arundel Cove.

• In 2009, the YARD eliminated the infiltration of contaminated groundwater to the stormwater system in the area of Building 30. In 2012, the YARD sealed a floor drain in the Battery Storage Room in Building 30 that was believed to drain to Curtis Creek.

• Eliminate or make provisions to include in the NPDES permit the discharge of all boiler system, air compressor and air conditioner condensate to stormwater drains as identified.

During June 2015 two floor drains were discovered, one in Building 40 and one in Building 58. Attempts to determine their discharge points by dying were unsuccessful. Following the dye tests both drains were sealed with hydraulic cement to render them unusable.

3.11. Waste, Garbage and Floatable Debris

Maintaining good general housekeeping practices at the YARD is essential to the prevention of contamination of stormwater. Procedures for managing materials used by the facility that could potentially impact stormwater quality are outlined in the USCG YARD Environmental Management System Manual and in this Plan. However, the management of other miscellaneous materials is necessary to maintain the cleanliness of the general YARD areas. Housekeeping tasks include:

• Perform a general site cleanup to remove miscellaneous trash as needed;

• Remove debris for disposal or recycling at regular intervals to prevent overfill of receptacles; and,

• Provide trash receptacles at areas throughout the facility, including each pier and on board each vessel being repaired.

3.12. Dust Generation and Vehicle Tracking of Industrial Materials

Instructions (see General Permit Part III.B.1.b):

Describe controls and procedures that will be used at your site to minimize discharges of waste, garbage, and floatable debris. Describe the location at your site where each control and/or procedure will be implemented.

Instructions (see General Permit Part III.B.1.b.):

Describe controls and procedures you will use at your site to minimize the generation of dust and off-site tracking of raw, final, or waste materials. Describe the location at your site where each control and/or procedures will be implemented.

MDE Industrial SWPPP Template, February 7, 2023 21

Most of the industrial area is paved or covered with gravel to minimize the creation of dust. Any construction project would have appropriate control measures (truck wash down, etc.) as part of that project and would be done as close to the source as possible. Hand sweeping/vacuuming is performed near the shiplift platform and other areas where dust/debris have accumulated from blasting activity.

Surfaced Areas Sweeping: All roadways and other paved areas, excluding areas designated for vehicle parking, are swept monthly. This includes sweeping of all paved YARD Industrial areas, including the waterfront and all piers. Parking areas are swept quarterly.

Off-site shipment of Industrial Materials are transported in either covered roll-offs or vacuum boxes.

Documentation of shipments is retained by the Environmental Branch.

4. Schedules and Procedures FOR MONITORING

The YARD is not required to conduct benchmark sampling under the MDE Industrial stormwater general permit because sector R, Ship and Boat Building and Repair Yards, which the YARD falls under, does not have separate benchmark monitoring requirements. However, the YARD is still required to conduct quarterly visual monitoring and will use the substantially identical outfalls identified in Attachment B for this.

Instructions (see General Permit Part III.C.5):

− Describe your procedures for conducting the five types of analytical monitoring specified by the General Permit, where applicable to your facility, including:

▪ Benchmark monitoring (General Permit Part V.B and relevant requirements in Appendix D); and

▪ Impaired waters monitoring as required by MDE (General Permit Part III.B.2);

− Depending on the type of facility you operate, and the monitoring requirements to which you are subject, you must collect and analyze stormwater samples and document monitoring activities consistent with the procedures described in General Permit Part V.B and relevant requirements in Appendix D. Refer to

General Permit Part V.E for reporting and recordkeeping requirements. Note: All monitoring must be conducted in accordance with the relevant sampling and analysis requirements at 40 CFR Part 136. Include in your description procedures for ensuring compliance with these requirements.

− If you are invoking the exception for inactive and unstaffed sites for benchmark monitoring, you must include in your SWPPP the information to support this claim as required by General Permit Part V.B.5.

− If you plan to use the substantially identical outfall exception for your benchmark monitoring requirements in

General Permit Part V.B.6 and/or your quarterly visual assessment requirements in General Permit Part V.A.3.d, you must include the following documentation:

▪ Location of each of the substantially identical outfalls;

▪ Description of the general industrial activities conducted in the drainage area of each outfall;

▪ Description of the control measures implemented in the drainage area of each outfall;

▪ Description of the exposed materials located in the drainage area of each outfall that are likely to be significant contributors of pollutants to stormwater discharges;

▪ An estimate of the runoff coefficient of the drainage areas (low = under 40%; medium = 40 to 65%; high

= above 65%); and

▪ Why the outfalls are expected to discharge substantially identical effluents.
