EDGEWOOD AREA WASTEWATER TREATMENT PLANT

STORM WATER POLLUTION PREVENTION PLAN UPDATE

ABERDEEN PROVING GROUND, MARYLAND

JUNE 2020

1. INTRODUCTION

1.1 Purpose

Federal regulations require storm water discharges from regulated industrial activities be permitted under the National Pollutant Discharge Elimination System (NPDES), or a state administered NPDES (40 Code of Federal Regulation (CFR) 122.26(b)(14)(i)-(xi)) (40 CFR 122, 2020a). The Maryland Department of the Environment (MDE) State Discharge Permit No. 12- SW-A (NPDES Permit No. MDR0000) covers general discharges from storm water associated with industrial activities as defined by the permit (MDE, 2014). The permit requires the development and implementation of a Storm Water Pollution Prevention Plan (SWP3) designed to minimize pollution through training, awareness, and source control. Implementation of this SWP3 and best management practices (BMPs) will allow Aberdeen Proving Ground (APG) to comply with MDE requirements. Appendix A provides a copy of the general permit. The letter authorizing coverage under the permit will be kept alongside a copy of the Notice of Intent (NOI) in Appendix B of this SWP3.

1.2 Facility Information

APG owns and operates a wastewater treatment plant (WWTP) for the treatment of domestic and industrial wastewater from the Edgewood Area (EA) of the installation. APG-EA WWTP is located at the east end of Beach Point Road (39.386027°N, -76.272768°W) and encompasses approximately 6 acres. The APG-EA WWTP is subject to Sector T (Treatment Works, Standard Industrial Classification (SIC) Code TW) requirements under the general permit. Figure 1 illustrates the general location of the WWTP on the installation.

Treatment at the facility consists of screening, grit removal, primary clarification, moving bed bioreactor system, rapid mixing, flocculation, secondary clarification, denitrification, ultraviolet disinfection, and post aeration. In accordance with Code of Maryland Regulations 26.08.04.04.C(2)(c), the WWTP has incorporated a bypass control system into its treatment process in which two holding tanks provide a minimum of 24-hour emergency holding (MDE, 2019). Sludge from the treatment process is transferred to holding tanks, where solids are kept in suspension through mixing. A few times per week, sludge is pumped to trucks (6,000 gallons per truckload) and transported for incineration. If decanting is needed, sludge decant is returned to the beginning of the treatment process. At the influent screen facility, removed solids accumulate under cover before transfer and disposal to an offsite landfill.

3. SITE MAP

Figure 2 presents a site map of the APG-EA WWTP. Storm water from the APG-EA WWTP discharges to Bush River (02130701). The Bush River is impaired for nutrients and polychlorinated biphenyls (PCBs) as determined by the MDE Integrated Report of Surface Water Quality (MDE, 2018) and in accordance with the Clean Water Act Section 303(d) (U.S.

National Archives and Records Administration, 1972). Total maximum daily loads have been established for nitrogen, phosphorus, and sediment. Storm water from the site is not discharged into a high quality receiving water designated as Tier 2.

The surface of the site is primarily grass with several buildings, concrete walkways, and a single asphalt road running through the center of the site. Approximately 1 acre of the site is covered with impervious surfaces. Runoff from the site is both diverted into the storm sewer system and discharged via Outfall A into King Creek or flows overland into four infiltration ponds. The site map includes the location of outfalls, storm water conveyances, storm water flow, storm water structural control measures, receiving waters, and potential pollutant sources.

4. POTENTIAL POLLUTANT SOURCES

Table 2 describes the potential pollutant sources at the site and their potential to pollute storm water discharges. The site activities, materials, and physical features possibly affecting storm water are identified in the table. For each potential pollutant source, a narrative assessment of its risk to storm water quality is included. Additionally, visual observations and pollutants of concern are addressed for all potential sources. Table 2 will be updated as necessary to reflect any changes that occur at the site.

a Significant spills include, but are not limited to, releases of oil or hazardous substances in excess of reportable quantities.

4.3 Non-Storm Water Discharges

Non-storm water discharges authorized under the permit (MDE, 2014) include—

Water used to fight active fires (not from fire system cleaning or testing);

Pavement wash waters where no detergents are used and no spills or leaks of toxic or hazardous materials have occurred (unless all spilled material has been removed);

Landscape watering, only if all pesticides, herbicides, and fertilizer have been applied in accordance with the approved labeling;

Routine external building wash down that does not use detergents and any dislodged paint chips are filtered;

Uncontaminated condensate from air conditioners, coolers, and other compressors and from the outside storage of refrigerated gases or liquids;

Irrigation drainage;

Uncontaminated groundwater or spring water;

Foundation or footing drains where flows are not contaminated with process materials;

and Incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of your facility, but not intentional discharges from the cooling tower (e.g., “piped” cooling tower blowdown or drains).

All storm water conveyance systems at the facility will be evaluated annually for the presence of non-storm water discharges in conjunction with the comprehensive site compliance evaluation.

Non-storm water certifications will be maintained in Appendix C.

4.4 Salt Storage

There are no salt piles at this facility. Small volume bags of salt are stored indoors and are not exposed to storm water.

4.5 Visual Monitoring Summary

The site has not historically had problems with materials contacting storm water runoff.

5. STORM WATER CONTROL MEASURES

APG has implemented storm water control measures to meet the non-numeric technology-based effluent limits in Part III.B of the permit (MDE, 2014). BMPs are defined as physical, structural, and/or managerial practices that, when used singly or in combination, prevent or reduce storm water pollution.

Recommended BMPs and implementation dates are proposed annually during the comprehensive site compliance evaluation. Proposed BMPs and schedules will be listed in the annual comprehensive report.

5.1 Non-Numeric Technology-Based Effluent Limits

Existing BMPs at the site are identified in Table 5 and will be implemented by site personnel.

Table 5. Existing BMPs

Existing BMPs Description

MINIMIZE EXPOSURE

Materials handled and stored undercover

Sludge from the treatment process is stored inside closed holding tanks. Removed solids from screening and grit removal are stored within the influent screening building before being bagged and disposed of inside a covered dumpster. Transferring sludge and hazardous materials during rain events is avoided.

Some of the hazardous materials (POLs, magnesium hydroxide, and PACI) are stored inside buildings and not subject to exposure.

APG IPM Plan Pesticides, herbicides, and fertilizer are not stored on site.

Application at the facility follows the guidance and procedures outlined in the APG IPM Plan.

GOOD HOUSEKEEPING

General good housekeeping All areas of the facility are maintained in a clean and orderly manner.

PREVENTIVE MAINTENANCE

Preventive maintenance program Facility vehicles and equipment, storage tanks, and treatment systems, are inspected regularly and preventive maintenance performed as necessary.

Existing BMPs Description

SPILL PREVENTION AND RESPONSE

Spill response equipment Spill response equipment is kept onsite, located near areas where spills may occur or where easily accessible for rapid response.

APG SPCC Plan The installation SPCC Plan contains spill prevention and response information.

Employee training Personnel have been formally trained in spill prevention and response procedures.

EROSION AND SEDIMENT CONTROLS

Paved access ways Only ~1 acre of the site is impervious. Paved walkways allow for easy access to the treatment plant structures.

Vegetated areas The majority of the facility is grass covered and the area around it is well vegetated.

MANAGEMENT OF RUNOFF

Storm water controls

Half the storm water runoff from the site is diverted into the storm water sewer system where it discharges to the Bush River. The remaining storm water runoff is diverted into one of four storm water management facilities on site. Two of the facilities are submerged gravel wetlands and the other two are micro bioretention facilities. These retrofits allow storm water to infiltrate instead of discharging from the site, providing one-inch treatment for each storm water management facility (equivalent to 4 acres of impervious area treated).

SALT STORAGE PILES

N/A Small volume bags of salt are stored indoors and are not exposed to storm water.

WASTE, GARBAGE, AND FLOATABLE DEBRIS

Covered dumpsters Garbage and recyclable materials are placed in their respective dumpsters that are located on site and dumpster lids are kept closed. Dumpsters are regularly emptied.

DUST GENERATION AND VEHICLE TRACKING OF INDUSTRIAL MATERIALS

Paved access road The facility is primarily vegetated with sidewalks and one paved road running through the center of the facility.

Legend:

POL = petroleum, oil, and lubricants PACI = polyaluminum chloride APG = Aberdeen Proving Ground IPM = Integrated Pest Management SPCC = Spill Prevention, Control, and Countermeasure

5.2 Sector-Specific Requirements

Control measures at the facility in place to comply with sector-specific requirements include covering exposed materials in the following areas: grit, screenings, sludge, and other solids handling, storage, or disposal areas.

Sludge from the treatment process is transferred to closed holding tanks where it is continuously mixed to prevent settling. During this holding process, sludge is not exposed to storm water.

The sludge is transferred to trucks (6,000-gallon capacity) and transported for incineration 2–3 times per week. If needed, sludge decant is returned to the beginning of the treatment process.

At the influent screen facility, removed solids accumulate inside and are not exposed to storm water.

6. SCHEDULE AND PROCEDURES

The permit requires the development of schedules and procedures for good housekeeping and maintenance control measures to include (MDE, 2014)—

A schedule for regular pickup and disposal of waste materials;

Routine inspections for leaks and conditions of drums, tanks, and containers; and A schedule for preventive maintenance activities, including regular inspections, testing, maintenance, and repair of all industrial equipment and systems, and control measures.

Documentation of inspection, maintenance, and repairs of control measures will be maintained in Appendix D. Documentation will include—

Date(s) of inspection and regular maintenance;

Date(s) of discovery of areas in need of repair/replacement, and for repairs;

Date(s) that the control measure(s) returned to full function; and The justification for any extended maintenance/repair schedules.

Table 6 provides a schedule for the inspection and maintenance of the existing control measures at the site. This table will be updated as necessary to address any changes in BMPs.

7. EMPLOYEE TRAINING

Training is required for all employees who work in areas where industrial materials or activities are exposed to storm water, or who are responsible for implementing the BMPs necessary to meet the conditions of the permit, including all members of the SWPPT. Training will be conducted annually, at a minimum, and cover the specific control measures and monitoring, inspection, planning, reporting, and documentation requirements of the permit. Training will address the following activities, where applicable:

Used oil management.

Spent solvent and paint management.

Disposal of spent abrasives.

Spill prevention and control.

Fueling procedures.

General good housekeeping practices.

Used battery management.

Waste recycling.

Used container controls, etc.

Training records will be maintained in Appendix E.

8. MONITORING, INSPECTIONS, AND REPORTING

8.1 Routine Facility Inspections

Once per quarter, a site assessment will be conducted at the WWTP to review the effectiveness of the SWP3. Inspections will be conducted at all areas of the site where industrial materials or activities are exposed or have the potential to be exposed to storm water. Inspections will also include storm water control measures used to comply with permit conditions. At least once per calendar year, this inspection will be conducted while a storm water discharge is occurring. The inspection will be documented with a checklist or other summary signed by the Duly Authorized Representative, with at least one member of the SWPPT taking part. The checklist will include—

The inspection date and time, Name and signature of inspector, Control measures in need of maintenance, Incidences of noncompliance and associated corrective actions, and

And certification that the site complies with the SWP3 and permit.

Routine facility inspections will be maintained in Appendix F, where a copy of the form has been provided.

8.2 Quarterly Visual Monitoring

Once per quarter, visual monitoring of storm water discharges will be conducted at the WWTP.

Grab samples will be collected within the first 30 minutes of a storm event where there is a measurable discharge. In areas subject to snow, one quarterly visual assessment must capture snowmelt discharge. Samples will be assessed for visual indicators of storm water pollution including color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other qualitative markers of pollution. Results will be documented on the Quarterly Visual Monitoring Form, provided in Appendix G. The samples are not required to be collected consistent with 40 CFR 136 procedures, but should be collected to be representative of the storm water discharge (40 CFR 136, 2020b). Visual assessments must be conducted at all outfalls, although if several outfalls are “substantially identical” then only one visual assessment must be conducted on the set of outfalls. Visual monitoring will be performed at these quarterly intervals: January 1 – March 31;

April 1 – June 30; July 1 – September 30; and October 1 – December 31. Visual monitoring results will be maintained in Appendix G.

8.3 Comprehensive Site Compliance Evaluation

A comprehensive site compliance evaluation will be performed annually at the WWTP.

Evaluations will be conducted by a member of the SWPPT or hired contractor. The evaluation is conducted to assess the effectiveness of this SWP3 and subsequent storm water BMPs, as well as identify any activity changes in material inventory and/or contaminant handling procedures. If a scheduled compliance evaluation overlaps with a routine facility inspection, the annual compliance evaluation may be used as one of the four routine facility inspections.

A report will summarize the scope of the evaluation, name(s) of personnel performing the evaluation, the date of the evaluation, and all observations relating to the implementation of the SWP3. The compliance evaluation report will identify any incidents of noncompliance.

Deficiencies and corrective actions are documented as proposed BMPs within the evaluation.

Any proposed or recommended management practices will be implemented as soon as practically feasible to prevent non-storm water discharges. Based on the results of the evaluation, the SWP3 must be modified as necessary. Refer to paragraph 9.3 (Corrective Action Deadlines) and paragraph 9.4 (Corrective Action Report) of this SWP3 for appropriate time frames. Comprehensive site compliance evaluations will be maintained in Appendix H, where a copy of the report form has been provided.

8.4 Record Retention

All records and information resulting from the monitoring activities required by the permit, including all records of analyses performed, calibration and maintenance of instrumentation, and original recordings from continuous monitoring instrumentation, must be retained for a minimum of 5 years.

9. CORRECTIVE ACTIONS

9.1 Conditions Requiring Review and Revision to Eliminate Problem

APG will review and revise the selection, design, installation, and implementation of control measures to ensure the condition is eliminated and will not be repeated in the future if any of the following conditions occur:

An unauthorized release or discharge (e.g., spill, leak, or discharge of non-storm water not authorized by any MDE NPDES permit) occurs at the facility.

A discharge violates a numeric effluent limit.

APG becomes aware, or MDE determines, that the control measures are not stringent enough for the discharge to meet applicable water quality standards.

An inspection or evaluation of the facility by MDE determines that modifications to the control measures are necessary to meet the non-numeric effluent limits in the permit.

APG finds in the routine facility inspection, quarterly visual monitoring, or comprehensive site compliance inspection that its control measures are not being properly operated and maintained.

9.2 Conditions Requiring Review to Determine if Modifications are Necessary

APG will review the selection, design, installation, and implementation of control measures to determine if modifications are necessary to meet the effluent limits in the permit if construction or a change in design, operation, or maintenance at the facility significantly changes the nature of pollutants discharged in storm water from the facility, or significantly increases the quantity of pollutants discharged (MDE, 2014).

9.3 Corrective Action Deadlines

APG will document discoveries of any of the conditions listed in Sections 9.1 or 9.2 within 24 hours of making the discovery. Subsequently, within 14 days of a discovery, APG will document any corrective action(s) to be taken to eliminate or further investigate the deficiency, or if no corrective action is needed, the basis for that determination. If APG determines that changes are necessary following its review, any modifications to control measures will be made before the next storm event, or as soon as practicable. If a deficiency cannot be addressed fully within 30 days, APG will call MDE’s Compliance Program and make them aware of the situation.

9.4 Corrective Action Report

Within 24 hours of discovery of any condition listed in Sections 9.1 and 9.2, the following information must be document:

Identification of the condition triggering the need for corrective action review.

Description of the problem identified.

Date the problem was identified.

Within 14 days of discovery of any condition listed in Sections 9.1 and 9.2, the following information must be document:

Summary of corrective action taken or to be taken (or, for triggering events identified in Section 9.2 where it was determine a corrective action is not necessary, the basis for this determination).

Notice of whether SWP3 modifications are required as a result of this discovery or corrective action.

Date corrective action initiated.

Date corrective action completed or expected to be completed.

This documentation with be included in the annual comprehensive report. Corrective action reports will be maintained in Appendix I of this SWP3.
