Storm Water Management



1.0            Purpose


The majority of stormwater runoff generated at Jefferson Lab flows towards Brick Kiln Creek to the east, eventually discharging into the Big Bethel Reservoir and further to tributaries of the Chesapeake Bay. A much smaller portion of stormwater runoff also flows into Sluice Mill Pond to the northwest, eventually draining into Deep Creek and the James River. Under the Clean Water Act and several states statutes, Jefferson Lab is responsible for ensuring proper management of water quality and quantity prior to discharging into all receiving surface waters. The Jefferson Lab Stormwater Management Program is designed to implement and satisfy the requirements of the following:


·         Virginia Stormwater Management Program (VSMP) Regulations – 9VAC25-870

·         Virginia Erosion and Sediment Control (E&SC) Regulations – 9VAC25-840

·         Virginia Department of Environmental Quality (DEQ) General Permit for Discharges of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4) – General Permit No. VAR040079

·         DEQ General Permit for Discharges of Stormwater from Construction Activities – 9VAC25-880

·         Virginia E&SC Handbook criteria

·         Jefferson Lab Annual Standards and Specifications for Stormwater Management and Erosion & Sediment Control


This chapter summarizes the specific requirements for stormwater management at Jefferson Lab and instructions in the form of references, appendices and other ES&H Manual chapters, where applicable. This chapter also discusses general stormwater management program aspects that are not captured elsewhere.


2.0            Scope


2.1              VSMP Regulations – 9VAC25-870


VSMP requirements are approved by the Virginia State Water Control Board and are authorized by the Virginia Stormwater Management Act to manage the quality and quantity of runoff resulting from regulated land-disturbing activities. VSMP regulations are administered by DEQ through the Virginia Pollution Discharge Elimination System (VPDES) permitting program that regulates point source pollution from MS4s, Construction, and Industrial Discharges. Several new regulatory requirements were enacted in July 2014; including the need for all counties, cities, towns and MS4s to establish a ‘local’ Stormwater Management Program. These regulations essentially provide three separate options for establishment of a local program:

1.      Become a VSMP Authority – only local government entities are authorized for this option due to having mechanisms in place such as local ordinances and enforcement response protocol

2.      Adopt ‘Annual Standards and Specifications’ approved by DEQ that describe how land-disturbing activities will be conducted at the facility

3.      Rely on DEQ for all plan reviews, inspections, and other program specifics


Since Jefferson Lab is a federal facility, the only option available is to adopt Annual Standards and Specifications approved by DEQ. Initial approval was obtained in 2015; annual approval from DEQ is required. As mentioned above, these Standards and Specifications describe the management process for all regulated land-disturbing activities occurring at the Lab (https://www.jlab.org/div_dept/dir_off/oa/secure/permits.html) and include information such as:

·         Administrative requirements

·         Personnel training and certification

·         Program implementation

·         Stormwater Pollution Prevention Plan (SWPPP) requirements

·         Environmental Site Design and Low Impact Development (LID) practices

·         Inspection and maintenance requirements

·         Variances, exceptions, prohibited stormwater discharges and authorized non-stormwater discharges


A major requirement under VSMP is the need for land-disturbing activities greater than 1-acre to obtain authorization under the General VPDES Permit for Discharges of Stormwater from Construction Activities (also known as Construction General Permit or CGP). Prior to issuance of a CGP, several steps must occur prior to receiving authorization from DEQ. For further details on this process, please refer to Jefferson Lab’s Annual Standards and Specifications for Stormwater Management and Erosion & Sediment Control.


Stormwater runoff that is not classified under a single point source is considered a nonpoint source controlled through E&SC practices as regulated by Virginia E&SC regulations.


2.2              Virginia E&SC Regulations – 9VAC25-840


The Virginia Erosion and Sediment Control Program is authorized by Virginia E&SC Law, Regulations, and Certification Regulations and is administered by DEQ to prevent destruction of property and natural resources caused by soil erosion, sedimentation and nonagricultural runoff from land disturbing activities.


Under the requirements of the Virginia E&SC Program regulations, an approved E&SC Plan is required for any land disturbance totaling 10,000-square feet to 1-acre in size. The basic framework of an approved E&SC Plan includes the controls that will be utilized during the project to meet the applicable requirements of the Virginia E&SC Handbook and the 19 E&SC Minimum Standards. 


2.3              DEQ Permit No. VAR040079 – General Permit for Discharges of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4)


The MS4 permit program is the result of the 1987 amendments to the Clean Water Act (CWA), commonly referred to as the Water Quality Act of 1987. In these amendments, Congress mandated that the Environmental Protection Agency (EPA) address non-point source pollution in stormwater runoff. In essence, EPA defined urban stormwater (previously considered a non-point source) as a point source because there was a physical location (or point) of discharge. In response to the Congressional action, EPA was required to develop a program to permit the discharge of stormwater from MS4s; from specific industrial activities that it considered to be significant sources of pollution; and from construction site runoff.


In 1990, the National Pollution Discharge Elimination System (NPDES) Permit Program was extended by EPA to include stormwater discharges. The new associated regulations established requirements for permitting discharges from industry, construction sites, and MS4s in municipalities with populations greater than 100,000. In 1999, the permit program was expanded to include discharges from communities with populations of less than 100,000 and was called the Phase II Stormwater Permit Program. These municipalities were required to obtain permit coverage by March 10, 2003 to discharge stormwater.


Stormwater discharges from Phase II (small) MS4s are authorized under the General Permit for Discharges of Stormwater from Small MS4s. These include MS4s operated by cities, towns, counties, and state and federal facilities.


The operator of a small MS4 is required to develop, implement and enforce a program that will reduce the discharge of stormwater pollutants to the ‘maximum extent practicable’ or MEP. This program is outlined through Jefferson Lab’s MS4 Program Plan that addresses the following six Minimum Control Measures (MCM):


2.3.1        MCM – 1: Public Education and Outreach on Stormwater Impacts

Implement a public education and outreach program that is designed with consideration of the following goals:


2.3.2        MCM – 2: Public Involvement/Participation

Public involvement actions shall include maintaining an updated MS4 Program Plan in conjunction with the Annual Report; updated Program Plan and Annual Report is posted on the Jefferson Lab webpage at:



Public participation shall include participation in at least four environmental-related activities on an annual basis that focus on reducing stormwater pollution, improving water quality, and increasing awareness of regional stormwater concerns.


2.3.3        MCM – 3: Illicit Discharge Detection and Elimination

Jefferson Lab shall develop, implement, and enforce a program to detect and eliminate illicit discharges to the Jefferson Lab MS4.


2.3.4        MCM – 4: Construction Site Stormwater Runoff Control

Jefferson Lab shall implement a Construction Site Stormwater Runoff Control program that is compliant with the requirements of VSMP regulations:


2.3.5        MCM – 5: Post-Construction Stormwater Management in New Development and Development on Prior Developed Lands

Jefferson Lab shall address post-construction stormwater runoff that enters the MS4 from new development and development on prior developed lands.


2.3.6        MCM – 6: Pollution Prevention (P2)/Good Housekeeping for Municipal Operations

Jefferson Lab shall implement P2/Good Housekeeping requirements established in the Spill Prevention Control and Countermeasures (SPCC) Plan, the Jefferson Lab Annual Standards and Specifications for SWM and E&SC, and the Jefferson Lab Environmental Management System (EMS).
