1.0 INTRODUCTION

1.1 REGULATORY INFORMATION

The Clean Water Act (CWA) amendments of 1987 contain the first provisions to specifically regulate discharges from storm sewer systems. The subsequent regulations contain requirements to prohibit non-storm water discharges into storm sewers and detail necessary controls to reduce the discharge of pollutants to the maximum extent practical. National Pollutant Discharge Elimination System (NPDES) permits have been established and applied to communities and municipalities to specifically regulate storm water discharges. The Environmental Protection Agency (EPA) implemented the Phase I rule of the NPDES permit system in 1990 to regulate storm water discharges associated with industrial activity; discharges from a municipal separate storm sewer system (MS4) serving a population of 250,000 or more; discharges from MS4s serving a population of 100,000 or more, but less than 250,000; and construction activity that disturbs five or more acres of land. The permit system was expanded in 1999 when the Phase II rule was issued for small MS4s serving less than 100,000 people and located within a Bureau of Census-delineated urbanized area, and construction sites that disturb one to five acres, as defined under 40 Code of Federal Regulations (CFR) 122.26(b)(16).

The U.S. Army Garrison Aberdeen Proving Ground (APG) NPDES Phase II MS4 Discharge General Permit No. 05-SF-5501 (see References, Section 11.0) was issued on November 12, 2004 by the Maryland Department of the Environment (MDE). The Phase II rule takes a best management practice (BMP) approach to reduce pollutant discharges in storm water and improve overall surface water quality. The NPDES Phase II Permit requires APG to satisfy six minimum control measures:

Public Education and Outreach Public Involvement and Participation Illicit Discharge Detection and Elimination (IDDE) Construction Site Storm Water Runoff Control Post Construction Storm Water Management Pollution Prevention and Good Housekeeping

Under the third measure, an IDDE program must be established, which includes the development and implementation of a plan to detect and eliminate illicit discharges to the storm sewer system.

1.2 INSTALLATION OVERVIEW

APG is located within Harford County, Maryland, and consists primarily of the Aberdeen Area (APG-North) and the Edgewood Area (APG-South). Other areas include the Churchville Test Track, Van Bibber Water Treatment Plant, and Hanson Reservoir also located within Harford County, Maryland, and Carroll Island and Graces Quarters located within Baltimore County, Maryland. In operation since 1917, APG is a military installation involved in the research, development, and testing of weapons systems, ordnance, and biological and chemical defenses. Historically, operations at APG have included the production and testing of explosives and chemical munitions, soldier training in the use and disposal of chemical agents, and the disposal of chemical agent-contaminated materials. APG provides general, administrative, and logistical support to the post’s tenants and satellite activities, and is responsible for the management and operation of the entire installation.

APG comprises approximately 72,500 acres. The installation is bordered by U.S. Route 40 to the west, Swan Creek and the Susquehanna River to the north, the Chesapeake Bay to the east and southeast, and finally by the Gunpowder River to the south. The Bush River divides the installation into two peninsulas. Numerous streams and creeks also flow through the site before discharging into either the Bush or Gunpowder River, or directly into the Chesapeake Bay.

2.0 PURPOSE

The purpose of this plan is to outline an approach for the inventory and inspection of storm water outfalls for illicit discharges, eliminate illicit discharges, discuss procedures to address spills and illegal dumping, and ensure that all non-storm water discharges to the storm sewer system are either permitted by MDE under NPDES or eliminated. The Directorate of Public Works (DPW) Environmental Division is responsible for maintaining and implementing this plan.

3.0 ILLICIT DISCHARGES

An illicit discharge is any discharge that is not composed entirely of storm water or not otherwise allowed. The following is a list of discharges that are considered to be illicit:

Sanitary wastewater sources such as:

Sanitary wastewater (usually untreated) from improper sewerage connections, exfiltration, or leakage

Effluent from improperly operating or improperly designed septic tanks

Overflows of sanitary sewerage systems

Automobile maintenance and operation sources such as:

Untreated commercial car wash wastewaters Untreated leakage of oils, gasoline, and other automotive fluids Improper oil, gasoline, or other automotive fluids disposal

Landscape irrigation sources such as:

Direct spraying of fertilizers, pesticides, or herbicides onto impervious surfaces

Over-application of fertilizers, pesticides, or herbicides onto landscaping

Other sources such as:

Laundry wastes Non-contact cooling waters Improper disposal of household toxic wastes Spills from roadway and other accidents Chemicals, hazardous materials, garbage, and sanitary sludge from landfills and disposal sites Trash and debris: littering and dumping, household or construction waste Improper disposal of restaurant grease

5.0 OUTFALL RECONNAISSANCE INVENTORY

In FY 2016, APG initiated an Outfall Reconnaissance Inventory (ORI), a field screening tool designed to inventory storm water outfalls and find and correct continuous and intermittent discharges without in-depth laboratory analysis. During this initial phase of the ORI, 25 outfalls were evaluated for illicit discharges. The results of the ORI can be found in Appendix A. As part of its IDDE program, APG will continue to conduct the ORI over the course of the next five years (FY 2017 – FY 2021), screening 20% (up to

100) of total outfalls per year.

5.1 DRY WEATHER SCREENING

In order to identify non-stormwater discharges, visual inspections will be conducted during dry weather periods (a period in which there has been no rainfall or no more than one-tenth of an inch of rain within a 48-hour period).

During these screenings, a variety of sensory, physical, and water quality parameters will be recorded at each outfall to assess conditions. At flowing outfalls this includes estimated flow rate, temperature, pH, ammonia, chlorine, turbidity, conductivity, total dissolved solids, dissolved oxygen, odor, color, turbidity, and presence or absence of floatables. There may be physical indicators of illicit discharges even if no flow is present. These include outfall damage, deposits/stains, abnormal vegetation, poor quality of pooled water, and benthic growth in the pipe. Further water quality monitoring will be conducted to confirm an illicit discharge and determine its source or origin.

Indicator parameters typically analyzed include detergents/surfactants, bacteria, fluoride, hardness, and potassium. Dry weather flow will be tested for applicable water quality parameters based on the preliminary findings of the field assessment.

Inspections will be conducted by a third party under the authority of the DPW Environmental Division. Outfall descriptions and inspection findings will be documented on the standard ORI form and maintained in Appendix A, where a copy of this form has been provided.

5.2 STORM SEWER SYSTEM MAP

As part of the ORI, the geospatial location and basic characteristics of individual storm water outfalls will be recorded (dimensions, shape, and component material). A preliminary assessment of APG’s available mapping data identifies approximately 500 outfalls slated for the ORI. Each identified outfall will be labeled with a letter, which identifies the general area (“A” for the Aberdeen Area and “E” for the Edgewood Area), and a number. Maps and photographs specific to each storm water outfall are provided alongside their respective ORI form in Appendix A.

APG maintains a general storm sewer system map for the installation detailing the locations of storm drains, outfalls, storm water management facilities, wetlands and receiving waters. The map will be revised periodically to include information collected from the ORI. Maps of the storm sewer system for the Aberdeen Area, Edgewood Area, and satellite locations are located in Appendix B.

6.0 ISOLATING AND REPORTING ILLICIT DISCHARGES

6.1 ISOLATING ILLICIT DISCHARGES

When an illicit discharge is discovered at an outfall or discharge point, field crews will trace the discharge to its source and identify the discharger. If and where necessary, the following techniques may be used to isolate the source of illicit discharges:

Dye-testing Visual sewer system inspections Sanitary/storm sewer surveys Ensuring proper connections of oil/water separators Ensuring proper connections of all drains and sewers Water sampling from manholes and/or other areas

Field crews will notify the DPW Environmental Division when an illicit discharge is discovered and report preliminary results from the source investigation. Field crews will document their findings on the Illicit Discharge Incident Tracking Sheet and provide this to the DPW Environmental Division. Illicit Discharge Incident Tracking Sheets will be maintained in Appendix C, where a copy has been provided.

6.2 PUBLIC REPORTING

APG will create a program to promote, publicize, and facilitate public reporting of illicit connections or discharges (e.g., a hotline). A public reporting hotline encourages active public stewardship and leads to early detection and correction. This program will be outlined in the installation IDDE policy to be developed during FY 2018 and disseminated to the public via the APG website.

6.3 IDDE DATABASE

To support its IDDE program, APG will create a database to track all illicit discharge incidents reported to the DPW Environmental Division from both public and internal reporting. Information to be documented in this database will include the information recorded on the Illicit Discharge Incident Tracking Sheet and any visual documentation:

Date the incident was reported to DPW Location where the incident occurred Spill Report Number (as appropriate) Description of the discharge in question Date and time the incident was observed Description of the incident Responsible party (if determined) Corrective action/resolution Incident case closure date

The information in the IDDE Database will be used to help track appropriate investigative and response measures, and to ensure all incidents have been appropriately mitigated. This database will be developed and implemented by the end of FY 2019. A summary of illicit discharge incidents will be provided in the MS4 Annual Report to MDE.

6.4 SPILL NOTIFICATION AND RESPONSE

Spill notification procedures were developed to ensure that appropriate APG personnel are contacted and required regulatory notifications are executed for all spill events. The APG Facility Response Plan contains regulatory procedures for spill prevention, planning, notification, and response, including the Spill Prevention, Control, and Countermeasure (SPCC) Plan.

The Aberdeen Proving Ground Fire and Emergency Services Division is the primary spill responder and can be reached from any installation phone by dialing 911 or 410- 306-0572. Any petroleum, toxic or hazardous substance spill, or any spill that occurs outside a covered (roofed) facility and poses a threat to human health or the environment must be reported to the APG Fire Department.

Spill notification must be conducted as soon as possible to ensure proper response and follow-up regulatory reporting. Individuals reporting a spill should provide a brief evaluation of the spill (location, substance, quantity and containment of spill) and determine the immediate steps that can be taken with available resources to provide safe and effective control and cleanup of the spill. Spill control and cleanup must be consistent with level of training. Spill cleanup activities should not be conducted if personnel are not appropriately trained.

7.0 ELIMINATING ILLICIT DISCHARGES

Once the source of an illicit discharge has been identified, steps will be taken to eliminate the discharge. The DPW Environmental Division will notify the discharger verbally and recommend an appropriate BMP for the facility to implement to eliminate the discharge. A follow up inspection will be performed following the elimination of the illicit discharge. Removal and correction of an illicit discharge or connection will be confirmed both at the source and downstream. If any outfall experiences an illicit discharge, the actions taken to eliminate the discharge will be documented on its respective Illicit Discharge Incident Tracking Sheet located in Appendix C.

8.0 COMPLIANCE AND ENFORCEMENT

As part of its IDDE program, APG will define enforcement tools that will address illicit discharge violations. In addition, APG will specify the activities that trigger progressively greater enforcement. Enforcement procedures will be outlined in the installation IDDE policy to be developed in FY 2018.

9.0 PREVENTING ILLICIT DISCHARGES

9.1 POLLUTION PREVENTION

Intermittent and transitory discharges are difficult to detect through outfall screening or indicator monitoring. The best way to manage these discharges and prevent them from occurring is to promote pollution prevention practices in the community. A description of illicit discharges and the policies intended to prevent them are described below.

9.1.1 Vehicle Washing in Non-Designated Areas

Vehicle wash water contains soap and residual contaminants that, if discharged into the storm drains, are considered illicit discharges. These pollutants have the potential to impact the health of aquatic plants and animals in the receiving waterways.

Government vehicle and equipment washing are conducted at designated locations, where wash water is collected and treated by an oil/water separator before discharging to the sanitary sewer. Locations of these wash areas are identified below:

Building E4301 – Not in operation Building E5359 – Not in operation Building 1116B – Not in operation Building E5779 – Not in operation Building 450 – Government vehicle and equipment washing Building 1060 – Aircraft, government vehicle and equipment washing Building 2379 – Self-service privately-owned vehicle washing Building 4728 – Government vehicle and equipment washing

Privately-owned vehicle washing activities can be performed at Building 2379, Auto Crafts Center, which has a closed loop wash system.

9.1.2 Vehicle Fluid Leaks and Spills

Small leaks or spills of petroleum, antifreeze, brake fluid, and other automobile fluids from vehicle maintenance and the high volume of vehicle traffic on APG, have the potential to contribute contaminants to the storm sewer system. Accumulated pollutants from automobiles are flushed from roadways and impervious parking lots during rainfall events and can be transported to receiving waterways. Intentional or accidental dumping of vehicle fluids onto the ground or directly into the storm sewer system can also impact storm water quality. APG requires any motor vehicle maintenance to be conducted indoors at designated locations where accidental spills can be contained, recycled, and/or disposed of properly. Locations and uses are identified below:

Building 450 – Government vehicle and equipment maintenance Building 1060 – Aircraft maintenance Building 2379 – Self-service privately-owned vehicle maintenance Building 4728 – Government vehicle and equipment maintenance Building E5360 – Government vehicle and equipment maintenance

9.1.3 Discharge of Untreated Sewage

There are three common ways that untreated sewage is discharged to the environment, which include: cross connections, leached sewage, and sanitary sewer overflows.

Cross connections are commonly caused by floor drains and equipment room sump pits that are incorrectly tied into the storm sewer system. This allows contaminated water to be discharged to the environment untreated. APG’s Floor Drain Policy stipulates that at no time will floor drains allow unauthorized discharges to the storm sewer system. Floor drains are to be utilized only if there is a legitimate need and with prior approval from DPW Environmental Division. Non-essential floor drains are permanently plugged and floor drains in new facilities are required to be connected to an oil/water separator.

Degraded sanitary sewer systems can leach sewage into the groundwater, later to be picked up in nearby drain tile, or directly into nearby cracked or broken storm sewer lines and transported to receiving waterways. Sanitary sewer overflows are releases of untreated sewage from the sanitary sewer system into the environment. Untreated sewage contains disease causing pathogens, including viruses, bacteria, worms, and protozoa, which have the potential to pose a substantial human health and environmental risk. Common causes of untreated sewage discharges are:

Rainfall infiltrating through the ground and into cracked or broken sanitary sewer piping.

Inflow of storm water directly into the sanitary sewer system from improperly connected roof and storm drains.

Undersized sanitary sewer conveyance piping or pumping equipment.

Blocked, broken or damaged sanitary sewer conveyance piping, or pumps.

Improperly installed or maintained sanitary sewer systems.

9.1.4 Discharge from Industrial and Commercial Activities

Runoff from industrial and commercial facilities may contain elevated petroleum, solvents, soap, and metal concentrations depending on the nature of activities conducted at these facilities. Elevated concentrations of pollutants within storm water runoff can be attributed to heavy traffic volume, large impervious areas, and specific industrial activities. Bulk storage of petroleum products and road salts also pose a potential threat of polluted discharges that could impact the environment. APG requires these areas to be properly maintained and inspected regularly to minimize risk associated with storm water runoff.

Discharges from industrial activities at APG are regulated by the site-specific Maryland State Discharge Permit No. 15-DP-2517, NPDES Permit No. MD0003565 (see References, Section 11.0). The activities regulated by this permit are:

Vehicle washwater and stormwater via Outfall 005 (Building 10301) Vehicle washwater and stormwater via Outfall 006 (Building E1464) Noncontact cooling water via Outfall 012 (Building 80G) Noncontact cooling water via Outfall 013 (Building 423) Water containing products of explosives detonations via Outfall 014 (Underwater

Explosives Facility) Facility areas identified in APG’s Storm Water Pollution Prevention Plan (SWP3), industrial activities as defined by 40 CFR 122.26(b)(14)

APG’s SWP3 describes BMPs used to limit pollutants’ contact with storm water at these industrial sites.

9.1.5 Construction Site Runoff and Swimming Pool Discharges

Runoff from construction sites may contain sediment, chemicals, and debris. At APG, all construction activities that disturb more than 5,000 square feet or 100 cubic yards of earth are required to have an MDE approved Erosion and Sediment Control Plan prior to disturbance (see References, Section 11.0). All construction runoff must be pretreated prior to discharge into the storm sewer system (see References, Section 11.0). Projects less than 5,000 square feet utilize same day stabilization and BMPs.

Maryland requires public or private swimming pools to obtain a general NPDES permit to discharge wastewater from swimming pools to surface or ground water. APG discharges wastewater from public swimming pools to the sanitary sewer system.

9.1.6 Improper Waste Disposal

Discarded trash, litter, and pet waste that enters a storm drain or waterway is considered an illicit discharge. Litter plugs up storm sewers, detracts from the aesthetic qualities of the landscape, and potentially harms aquatic wildlife. Trash and floating debris in waterways have become significant pollutants, especially near urban areas where large volumes of trash can be generated in a concentrated area. The presence of pet waste in storm water runoff has a number of impacts on surface water quality with fecal coliform perhaps being the greatest. Bacteria can pose health risks to humans and other animals and result in the spread of disease. The release of nutrients from the decay of pet waste promotes weed and algae growth, limiting light penetration, and the growth of aquatic vegetation. This in turn can reduce oxygen levels in the water, affecting fish and other aquatic life. APG works closely with the community to educate members on their impact to the environment, the installation operating procedures, and the potential environmental and mission impacts of departing from these operating procedures.

9.2 STORM DRAIN STENCLING

Storm drain stenciling sends a clear message to keep trash and debris, leaf litter, and pollutants out of the storm sewer system, and may deter illegal dumping and discharges. Stenciling may increase watershed awareness and neighborhood stewardship and can be used in any neighborhood with enclosed storm drains.

Approximately 95% of all storm drains on APG have been marked with colorful signs that read “No Dumping – Drains to Waters of the State”. As part of the MS4 requirements, APG inspects 20% of marked storm drains annually for deterioration and replaces the markers as needed.

9.3 PUBLIC EDUCATION AND OUTREACH

APG actively participates in Earth Day and Pollution Prevention Week events to inform APG and the surrounding community of storm water pollution prevention opportunities.

APG will ensure information pertaining to illicit discharges is distributed to the community at these events. Storm water and related environmental articles are periodically published in the APG News, APG’s weekly newspaper. At least once every five years, APG will publish an article related to illicit discharges. Storm water pollution prevention and spill notification and response training programs, available online; have also been established to provide educational outreach to the APG community.

9.4 EMPLOYEE TRAINING

MS4 operators are required to provide training to appropriate staff on control measures for storm water pollution prevention. Training is available online and will be conducted annually. Training will include how to identify illicit discharges, spill reporting and response procedures, and how to eliminate illicit discharges. Training will be reported in the MS4 annual report due to MDE annually.

9.5 BEST MANAGEMENT PRACTICES

To reduce illicit discharges to the maximum extent practical, APG developed BMPs for the six minimum control measures outlined in the Phase II General Discharge Permit (NPDES Permit No. MDR055501). The effectiveness of these BMPs will be reported in the MS4 annual report to MDE.

9.6 STORM WATER REGULATIONS AND ENVIRONMENTAL PLANS

9.6.1 APG Regulation 200-40

APG Regulation 200-40, Erosion and Sediment Control and Storm Water Management, was revised in August 2016 to include updated information. This regulation prescribes policies and procedures for erosion and sediment control and storm water pollution prevention at APG. These policies and procedures have been developed in order to reduce the introduction of contaminants in storm water runoff that may impact the quality of receiving waterways.

9.6.2 Construction Activities

MDE requires all new construction greater than 5,000 square feet or 100 cubic yards of cut/fill, obtain approved Erosion and Sediment Control and Storm Water Management Plans prior to earth disturbance. Construction activity erosion and sediment controls inhibit the transport of sediment within storm water runoff to receiving waterways.

Storm water management controls and practices help alleviate the adverse impacts associated with increased storm water runoff attributed to the increase in impervious area and the loss of natural storm water storage associated with development. Proper management of the increased runoff will minimize local flood damage to public and private property, control stream channel erosion, sediment deposition, and non-point pollutant transport.

9.6.3 SWP3

The APG SWP3 was established in accordance with APG’s site-specific State Discharge Permit 15-DP-2517, NPDES Permit No. MD0003565 (see References, Section 11.0). This document is reviewed annually to ensure continued regulatory compliance.

9.6.4 SPCC Plan

APG’s SPCC Plan has been prepared in accordance with the oil pollution prevention regulations, 40 CFR 112. The SPCC Plan establishes a comprehensive spill prevention program that minimizes the potential for petroleum discharges to reach nearby waterways. The SPCC Plan addresses all relevant spill prevention, control, and countermeasures necessary for bulk storage of oils at APG.

10.0 IDDE PROGRAM EVALUATION

Annually, APG will review the goals established for this IDDE program to measure the effectiveness of the program and adapt the program based on discharge problems, pollutants, and emerging technologies.

Tracking the various system components of the IDDE program will identify which aspects of the program are improving the water quality of the MS4. To track its IDDE program, APG will provide in their MS4 annual report to MDE:

An updated map to reflect outfalls evaluated during the ORI Surveyed streams with locations of obvious, suspect, and potential discharges, and locations of dumping sites ORIs completed during the reporting period Water quality sampling results for specific outfalls and storm drains, where applicable Number of illicit discharges/connections found and eliminated Status of any corrective actions taken

The IDDE Plan will be reviewed annually during FY 2017 – FY 2021 and updated if needed. Thereafter, the IDDE Plan will be reviewed once every five years.
