SMALL MUNICIPAL SEPARATE STORM SEWER SYSTEM

STORM WATER MANAGEMENT PLAN UPDATE

ABERDEEN PROVING GROUND, MARYLAND

MAY 2020

1. INTRODUCTION

1.1 Purpose

Federal regulations require storm water discharges from small municipal separate storm sewer systems (MS4s) as defined under Title 40 of the Code of Federal Regulations (CFR) 122.26(b)(16)(iii) be permitted under the National Pollutant Discharge Elimination System (NPDES), or a state administered NPDES (40 CFR 122.26(b)(14)(i)-(xi))( U.S. National Archives and Records Administration, 2020). The Maryland Department of the Environment (MDE) General Discharge Permit No. 13-SF-5501 (NPDES Permit No. MDR055501) (MDE, 2018) covers storm water discharges from eligible small MS4s including those properties that—

Are owned or operated by the State of Maryland or the United States and located within an urbanized area; and

Serve developed land area greater than 5 acres and have at least 10% impervious area property wide; or

Are already covered under an NPDES small MS4 Phase II general permit.

The permit requires the implementation of six minimum control measures (MCMs) by all entities covered by a general permit. These six measures are—

Public Education and Outreach, Public Involvement and Participation, Illicit Discharge Detection and Elimination (IDDE), Construction Site Runoff Control, Post-Construction Management, and

Pollution Prevention and Good Housekeeping.

In addition to the six MCMs, the permit establishes requirements for impervious area restoration for 20% of existing developed lands that have little or no storm water management. This Storm Water Management Plan (SWMP) contains best management practices (BMPs), measurable goals, schedules of implementation, and other information required by the permit.

Implementation of this SWMP and BMPs allows Aberdeen Proving Ground (APG) to comply with MDE requirements. A copy of the general permit is located in Appendix B. The letter authorizing coverage under the permit is kept alongside a copy of the Notice of Intent (NOI) in Appendix C of this SWMP.

1.2 Installation Overview

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 is home to more than 80 tenants and a host of satellite and private activities. APG provides general, administrative, and logistical support to the installation’s tenants and satellite activities, and is responsible for the management and operation of the entire installation.

APG occupies 72,283 acres and is located on the western shore of the northern Chesapeake Bay. The installation lies approximately 20 miles northeast of the city of Baltimore. The installation is geographically divided into two areas, separated by the Bush River. The Edgewood Area is to the west of the river, and the Aberdeen Area lies to the east. The Edgewood Area consists of the Edgewood peninsula, Pooles Island, Graces Quarters, and Carroll Island. The Aberdeen Area consists of the Aberdeen peninsula and Spesutie Island.

APG also includes several smaller noncontiguous properties: Churchville Test Area, Atkisson Dam and Reservoir, Van Bibber Water Treatment Plant and Hanson Reservoir, and Eastern Shore Towers. All of APG lands lie in Harford County, except for Carroll Island and Graces Quarters which lie in Baltimore County, and the Eastern Shore Towers, which are located in Kent County. Nearly half of APG’s total acreage is open water including numerous tidal and nontidal creeks, as well as portions of the Chesapeake Bay and two estuarine Rivers (Gunpowder River and Bush River).

3. MCMS AND BMPS

3.1 Public Education and Outreach

Information distribution and community outreach are means to raise the awareness of APG employees, residents, and visitors as to how their actions impact storm water runoff and water quality. Appropriate BMPs include activities such as storm drain stenciling, annual training for personnel, and distributing educational materials (e.g., posters, brochures, and fact sheets) to the public.

APG publishes storm water related informational articles in the APG community newspaper, APG News, semiannually. The articles serve to educate the public about the effects of pollutants in storm water and encourage public involvement in pollution prevention. In addition, environmentally friendly displays are showcased at various community events. APG promotes annual training of installation personnel in spill reporting and response and basic storm water pollution prevention.

The majority of storm sewer drains on APG have been marked with colorful signs that read “No Dumping – Drains to Waters of the State.” APG’s storm drain marker program raises public awareness about the connection between storm drains and the health of local waters.

APG has established a successful recycling program for all tenant organizations. The recycling program includes single stream collection of #1–7 plastics, excluding styrofoam. APG also maintains a qualified recycling program that collects steel, copper, brass, oils, and tires. The private contractor in charge of installation housing provides residential recycling. Public education and outreach BMPs and measurable goals are located in Table 1.

3.2 Public Participation and Involvement

Employees and local residents should have an active role in the development and implementation of the storm water program. The work of just a few motivated individuals can have a significant impact on storm water management. If employees and residents have an active role in implementing storm water controls, then they are more likely to maintain and support the BMPs implemented, rather than raise public challenges. BMPs supporting this MCM are continually evaluated and monitored. In accordance with the general permit, APG will comply with State and Federal public notice requirements for storm water management actions or decisions.

APG facilitates public involvement through key partnerships and collaborative efforts. These partnerships include regular meetings with Maryland Environmental Partnership and the Chesapeake Bay Action Team to discuss updates and information on the Chesapeake Bay Program and to discuss regional and local compliance updates, sustainability, pollution prevention, and miscellaneous networking issues. APG hosts awareness-focused events for the APG community on Earth Day and during Pollution Prevention Week. In addition, twice a year, in partnership with the Alliance for the Chesapeake Bay Project Clean Stream, APG hosts a shoreline cleanup. APG encourages the public to report storm water issues, including illicit discharges and storm water pollution to their dedicated storm water hotline. The hotline has been advertised via APG News, social media, and the APG website. Public participation and involvement BMPs and measurable goals are located in Table 2.

3.3 IDDE

Federal regulations define an illicit discharge as “...any discharge to an MS4 that is not composed entirely of storm water...” with some exceptions. These exceptions include discharges from NPDES-permitted industrial sources and discharges from fire-fighting activities.

Examples of illicit discharges are domestic and industrial wastewater, paint, chemicals, auto fluids, vehicle wash water, and fuel spills.

APG has an established IDDE Program, the purpose of which is to determine the types and sources of illicit discharges and effectively eliminate them. This program includes maintaining an updated storm sewer system map, establishing and implementing an IDDE policy and IDDE plan, and illicit discharge educational outreach.

APG maintains a storm sewer system map detailing drainage areas, storm drain and outfall locations, and storm water BMP locations and descriptions. APG drafted an IDDE Policy to prohibit non-storm water discharges into the MS4 and outline appropriate enforcement procedures and actions. This policy will be incorporated into APG Regulation (APGR) 200-40, Environmental Quality (APG, 2017). In May 2017, APG developed an IDDE Plan to detect and address non-storm water discharges, including illegal dumping, into the MS4. The plan includes:

Procedures to field screen storm drain outfalls on a consistent basis;

Inspection procedures for identifying the source of any suspected illicit discharges to the storm drain system;

Enforcement and penalty procedures;

Procedures to address spills and illegal dumping; and

Means to inform military personnel, employees, and residents of illegal discharges and improper waste disposal.

Public education and outreach regarding ways to detect and eliminate illicit discharges is an integral part of this MCM. APG’s storm water hotline publicizes and facilitates public reporting of illicit discharges. Informative brochures and guidance, specific for different audiences (installation employees versus residents), has been developed and disseminated to educate the public on illicit discharges. IDDE BMPs and measurable goals are located in Table 3.

3.4 Construction Site Storm Water Runoff Control

The purpose of construction site runoff control is to minimize erosion, retain sediment onsite, and manage storm water discharges so they do not cause or contribute to violations of applicable water quality standards. Construction sites have the potential to contribute more sediment to local rivers and streams than nonconstruction sites. Sediment runoff rates from construction are typically 10 to 20 times greater than those of agricultural lands and 1,000 to 2,000 times greater than those in forest lands. These sediment discharges cause physical, chemical, and biological harm to the nation’s waters.

Maryland has a statewide erosion and sediment control (ESC) program. The Environment Article, Title 4, Subtitle 1, Annotated Code of Maryland requires ESC for earth disturbances greater than 5,000 square feet (MDE, 2019a). ESC Plans for State and Federal development projects are approved and enforced by MDE. APG intends to rely on this “qualifying local program” as defined in the general permit to comply with this MCM. MDE believes this is sufficient for general permit compliance. APG will track ongoing and new construction projects.

In order for construction to commence, construction sites must be properly permitted and ESC Plans and SWMPs approved. Construction sites that disturb one or more acres of land must submit a NOI for coverage under MDE’s General Permit for Storm Water Associated with Construction Activity. All new construction at APG will require separate permitting for pollutant run-off control and ESC for construction activities that disturb 5,000 square feet or more of earth or involve 100 cubic yards or more of earth movement.

Currently, operators of construction projects are required to submit ESC Plans and SWMPs to MDE for approval before commencement of construction, which satisfies one of the metrics for this MCM. Directorate of Public Works (DPW) – Environmental Division (ED) receives copies of all construction plans during the planning process and reviews all plans before construction projects are approved. Table 4 lists the measurable goals and BMPs for this MCM.

3.5 Post Construction Storm Water Management

The purpose of this MCM is to maintain natural runoff cycles from new development and redevelopment projects that disturb 5,000 square feet or more. A post construction storm water management program can increase infiltration and decrease runoff effects with the use of low-impact development (LID), site-specific storm water designs, and inspections of storm water controls.

Maryland has a statewide storm water management program. The Environment Article, Title 4, Subtitle 2, Annotated Code of Maryland requires storm water management implementation for earth disturbances greater than 5,000 square feet (MDE, 2019e). SWMPs for State and Federal development projects are approved and enforced by MDE. APG intends to rely on this “qualifying local program” as defined in the general permit to comply with this MCM. MDE believes this is sufficient for general permit compliance. APG developed a program to track, inspect, and maintain post construction storm water BMPs in 2017.

In an effort to reduce energy consumption and optimize life cycle performance, Leadership in Energy and Environmental Design (LEED) Silver Certification is required for all new vertical building construction projects by Army policy dated 17 January 2017, Sustainable Design and Development Policy Update (Office of the Assistant Secretary of the Army (OASA), 2017).

The Army’s Sustainable Design and Development Policy Update also mandates LID measures be incorporated into new and renovation construction projects (OASA, 2017). LID is also required by Department of Defense (DOD) policy dated 19 Jan 2010, DOD Implementation of Storm Water Requirements under Section 438 of the Energy Independence and Security Act (EISA) (Office of the Under Secretary of Defense (OUSD), 2010). The U.S. Environmental Protection Agency (EPA) has EISA guidance to reduce storm water discharges from development at Federal facilities (U.S. Code, 2007). LID designs are essential in minimizing runoff created from development. Post-construction site runoff control BMPs and measurable goals are located in Table 5.

3.6 Pollution Prevention and Good Housekeeping

Good housekeeping measures are designed to reduce pollution that collects on streets, parking lots, open spaces, and vehicle maintenance areas, which discharges to local water bodies. The pollutants that are discharged can affect receiving water quality or impair the storm sewer system. Pollution prevention and good housekeeping BMPs are designed to maintain the storm sewer system and its outfalls by preventing damage caused by neglect. All pollution prevention and good housekeeping policies should be documented in the annual reports submitted to MDE. APG prevents or reduces polluted storm water runoff from operations through the development and implementation of a good housekeeping program, inspections, employee training, and runoff controls for fleet and building maintenance activities.

All storm water discharges on APG are properly permitted. Facilities discharging comingled storm water and wastewater are permitted under NPDES Discharge Permit No. MD0003565 (MDE, 2017). The permit establishes effluent limitations and monitoring requirements.

Discharges from storm water associated with industrial activities are permitted under General Discharge Permit No. 12-SW-A (MDE, 2014). Under the general permit, routine inspections and visual assessments are conducted.

APG has developed and implemented a Good Housekeeping Plan, located in Appendix D. This plan identifies the facilities that conduct municipal operations and fell outside the definition of an industrial activity, but were considered potential sources of pollution. These facilities will be periodically inspected for proper implementation of good housekeeping BMPs. These inspections will be maintained onsite at each facility and in Appendix E. The Good Housekeeping Plan also contains the APG Spill Prevention and Response Standard Operating Procedure, which details spill response, notification, and reporting procedures. Spills and leaks at APG facilities will be tracked on a spill log and maintained in Appendix F.

APG implements an Integrated Pest Management Plan that details pesticide and herbicide management on the installation. APG also discourages the use of fertilizer by individuals or groups throughout the installation. The DPW Pest Management Branch determines the minimum pest management requirements for the installation, while the Directorate of Family and Morale, Welfare, and Recreation (MWR) determines the minimum pest management requirements for the golf courses.

APG will continue the recycling efforts on the installation to reduce the amount of materials sent to the landfill and support environmental stewardship. Pollution prevention training is also available to the public on the APG website and in CD format. Pollution prevention and good housekeeping BMPs and measurable goals are located in Table 6.

4. CHESAPEAKE BAY RESTORATION AND MEETING TOTAL MAXIMUM DAILY LOADS

In 2010, the Chesapeake Bay total maximum daily loads (TMDLs) was established by the EPA for the six Bay States (Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia) and the District of Columbia. The TMDL describes the level of effort that is necessary to meet water quality standards and restore the Chesapeake Bay. The TMDL is an aggregate of the load allocations for nonpoint sources, the wasteload allocations for point sources, and margins of safety.

Maryland’s Watershed Implementation Plan specifies the nutrient and sediment load reductions required to address the Chesapeake Bay TMDL by 2025 (MDE, 2010). The general permit makes progress toward that strategy by requiring small MS4s to commence restoration efforts for 20% of existing developed lands that have little or no storm water management. Restoration efforts may include the use of environmental site design practices, structural storm water BMPs, retrofitting, stream restoration, or other alternative restoration practices. The permit requires permittees to—

Develop a baseline impervious area assessment and submit within the first year of permit issuance for MDE review;

Develop and implement an impervious area restoration work plan within the first year of permit issuance, which outlines the development of a new restoration program for the agency and includes appropriate budget, staffing, and resources to comply with impervious area restoration requirements;

Develop a restoration activity schedule and provide a list of water quality improvement projects that will be implemented by 2025 to meet Chesapeake Bay restoration targets; and

Develop a BMP database to track implementation, and comply with inspection and maintenance requirements.

APG is currently exceeding the Chesapeake Bay restoration requirement through the removal of impervious surface, installing, or retrofitting storm water management in areas with little or no storm water treatment and shoreline stabilization. These efforts are outlined in the U.S. Army Corps of Engineers Chesapeake Bay Total Maximum Daily Load Restoration Plan for Aberdeen Proving Ground (U.S. Army Corp of Engineers, 2019).

5. REPORTING

APG will evaluate progress toward achieving compliance with all permit requirements and the appropriateness of implemented BMPs by submitting annual progress reports to MDE.

Reporting for the six MCMs and progress towards meeting the 20% impervious area restoration requirement will include all required information specified in the MS4 Progress Report (provided in Appendix D of the permit). Reporting for the six MCMs will be submitted in years 2 and 4 of the permit term. The reporting period is based on State fiscal year (i.e., July 1 – June 30). MS4 Progress Reports will be submitted no later than October 31 of each year with the first report due October 31, 2019. Annual reports will be signed by the duly authorized representative and maintained in Appendix G.

6. RECORDKEEPING

APG will maintain records for at least 3 years after termination of the general permit. In addition to the information required in MS4 Progress Reports, APG will submit any additional supporting documentation at the request of MDE. Records and information pertaining to APG’s MS4 program will be made available to the public during regular business hours.

GOOD HOUSEKEEPING PLAN

D-1. BACKGROUND

Municipal operations can be a significant source of pollutants in storm water runoff, especially when uncontrolled. The National Pollutant Discharge Elimination System (NPDES) General Permit for Discharges from State and Federal Small Municipal Separate Storm Sewer Systems (NPDES No. MDR055501) requires the development and implementation of a good housekeeping plan for facilities where maintenance of vehicles or heavy equipment is conducted and handling of any of the following materials occurs: deicers, anti-icers, fertilizers, pesticides, road maintenance materials such as gravel and sand, or hazardous materials (Maryland Department of the Environment (MDE), 2018). The Aberdeen Proving Ground (APG) Good Housekeeping Plan has been developed to meet the requirements of minimum control measure #6 as outlined in the general permit, with the intent to reduce the discharge of pollutants from municipal-type facilities at APG.

D-2. FACILITY INFORMATION

APG owns or operates facilities that conduct municipal operations, which have the potential to contribute pollutants to storm water runoff. For the purpose of this plan, municipal-type facilities at APG are those not classified as industrial activities (which would require separate NPDES permits). APG has also chosen to include non-municipal facilities with the potential for significant impact on storm water.

A complete list of APG facilities and operations covered under this plan can be found on the Facility Inventory List, located in Table D-1. The inventory includes a description of the facility, associated municipal operations, and site-specific good housekeeping measures being implemented. Pollutants of concern associated with municipal operations are listed in Table D-2.

D-3. BEST MANAGEMENT PRACTICES

The installation and maintenance of control measures for municipal operations is a critical step to managing an effective storm water program. Based on the Facility Inventory List, a set of best management practices (BMPs) have been selected. Table D-3 identifies the appropriate control measures APG will implement to prevent or reduce the amount of storm water pollution generated by municipal operations.

D-4. INSPECTIONS

APG will inspect facilities for compliance with the selected BMPs. The inspection will be documented with a checklist, found in Table D-4. The checklist will include date of inspection, name of inspector, and identify whether good housekeeping BMPs are being implemented.

Facilities are inspected either quarterly or annually. Inspection frequency was determined based on a facility’s potential to impact storm water due to operations. The inspection schedule is detailed in the Facility Inventory List. Good housekeeping inspections will be maintained in Appendix E of the APG Storm Water Management Plan (SWMP).

D-2

D-5. SPILLS AND LEAKS

The APG Spill Prevention and Response Standing Operating Procedure (SOP) details spill response, notification, and reporting procedures. The SOP can be found in Annex 1. Spills and leaks will be tracked and recorded in Appendix F of the APG SWMP where a copy of the spill log has been provided. Documentation with include the date of release, location, content, capacity, and response actions.
