Stormwater Management

In managing the Christopher Newport campus grounds, we strive to be good environmental stewards. We work closely with the Virginia Department of Environmental Quality (DEQ) to ensure our efforts are up to current standards and practices.

The stormwater management program plan is based on six minimum control measures as required by the Virginia General Permit. These goals and objectives were developed to reduce the discharge of pollutants from the university's Municipal Separate Storm Sewer System (MS4) to the maximum extent practicable, protect water quality, ensure compliance with water quality standards, and to satisfy the appropriate water quality requirements of the Clean Water Act and its attendant regulations.


The Virginia Pollutant Discharge Elimination System Permit for Discharges of Stormwater from Small MS4s requires Christopher Newport to develop and implement a comprehensive stormwater management program consistent with the Virginia General Permit.

The University re-registered for continuation of coverage and was approved by the DEQ on July 1, 2013 (permit number VAR040090). The new general permit is valid until June 30, 2018.

The MS4 Annual Report serves to convey the required information and detail the status of compliance with all permit conditions, as well as the appropriateness of best management practices identified in the MS4 Program Plan toward achieving measurable goals for each minimum control measure.


Pollution prevention is any practice that reduces, eliminates or prevents pollution at its source. Reducing the amount of pollution produced means less waste to control, treat or dispose. Less pollution also means fewer hazards are posed to public health and the environment.

Under our permit, we must develop, implement and enforce a program that includes the following six minimum control measures:

  1. Public education and outreach on stormwater impacts
  2. Public involvement and participation
  3. Illicit discharge detection and elimination
  4. Construction site stormwater runoff control
  5. Post-construction stormwater management in new development and redevelopment
  6. Pollution prevention/good housekeeping for municipal operations

These control measures are designed and implemented to control the discharge of pollutants from our storm sewer system to the maximum extent practicable in a manner that protects the water quality in nearby streams, rivers, wetlands and bays.

Illicit Discharge Detection and Elimination (IDDE)

The IDDE policy and program provide for the protection of the environment at CNU and the surrounding areas.

An illicit discharge is the discharge of any substance into a storm sewer system* that is not stormwater. Some examples of these substances include:

  • Cleaning supplies
  • Construction waste (e.g., debris, sludge)
  • Vehicle washing
  • Paint
  • Vehicle oil
  • Pet waste

The following do not constitute an illicit discharge:

  • Firefighting activities
  • Landscape irrigation and lawn watering
  • Foundation/footing drains
  • Water line flushing
  • Discharges of potable (drinkable) water sources
  • Street wash water
  • Air conditioning condensation

*Storm sewers are designed to carry stormwater and runoff. Storm sewers are not treated and lead directly into our natural environment. Substances that are not stormwater should never be released into the storm sewer system. The University's storm sewer inlets are marked with a “No Dumping – Drains to Bay” medallion.

If you witness an illicit discharge, you can report it to the Grounds Department by clicking the button below.

Standard Operating Procedures (SOPs)

CNU Stormwater Pollution Prevention Training

As part of our MS4 program the University maintains a Stormwater Pollution Prevention Plan (SWPPP)

An SWPPP is designed to reduce the impact of stormwater runoff on receiving water bodies to the maximum extent practicable and to meet water quality standards, and identifies the following:

  • Stormwater pollution prevention team
  • Stormwater discharges at the campus
  • Actual and potential sources of stormwater contamination
  • Structural and non-structural best management practices
  • Good housekeeping practices
  • Standard operating procedures for activities with the potential to impact water quality

Stormwater Pollution Prevention Training SWPPP training is available to all members of the campus community. We provide training to all employees whose job duties may include activities with the potential to contribute to stormwater pollution.

Public Education and Outreach

Only Rain Down the Drain A reminder about water pollution with an emergency call list on the back.


Be a Solution to Water Pollution An informational flier about water pollution.


Guidelines for Charity Car Wash Fund Raisers Car washes to raise funds for charities, schools activities or community groups often occur in densely populated urban areas. Car-washing activities can affect water quality if not properly managed. Wash water from these activities may flow into surface waters or into a storm drain.


CNU Garden Symposium The Grounds Department provides an educational stormwater table at the annual Garden Symposium. We provide advice and literature related to rain gardens, stormwater runoff, urban nutrient management and environmentally friendly landscaping.


Construction Sites

Construction projects that disturb more than one acre are required to obtain a Virginia Stormwater Management Program construction permit from the Virginia Department Environmental Quality.
