City of Newport News
2024-2029 MS4 Program Plan
inspections are performed by Department of Engineering staff in accordance with the MS4 –
Industrial / High Risk Runoff Facility Inspections (SOP).
➢ “High Risk”
High Risk facilities are industrial and commercial entities where non-stormwater discharges to the
City’s MS4 have been identified in the past via reported/discovered illicit discharges, or where
discharges are likely to occur based on the type of facility/business. Facilities may include, but
are not limited to, major automotive facilities such as repair shops, body shops, auto detailers,
tire repair shops, and service stations. Major automotive facilities are inspected by Newport News
Fire Department Community Risk Reduction Division; stormwater pollution incidents are enforced
under the Virginia Statewide Fire Prevention Code. All other facilities are inspected by
Department of Engineering staff in accordance with the MS4 – Industrial / High Risk Runoff Facility
Inspections SOP. All inspections are conducted at least once every five years; these inspections
are tracked by Engineering for inclusion in the annual report.
Facilities of concern that may require a VPDES permit from DEQ are referred to DEQ Tidewater
Regional Office; referrals are tracked in the database for inclusion in each annual report.
➢ “High Risk Bacteria”
High Risk Bacteria facilities are those locations where illicit discharges due to sanitary sewer
overflows have occurred that warrant future re-inspections. Inspections occur at least once every
two years and are tracked by Engineering for inclusion in the annual report.
➢ “VPDES Permitted”
Facilities with individual industrial VPDES stormwater permits or coverage under the industrial
stormwater general permit may be included in the City’s program at its discretion. VPDES
Permitted facilities information is obtained from DEQ. Facilities are reviewed to determine if
inclusion in the database and inspection program is warranted; a facility is included if it drains to
the City’s MS4 and the activities onsite are considered a potential source of stormwater
pollutants.
VPDES Permitted facilities are inspected at least once every five years by Department of
Engineering staff in accordance with the MS4 – Industrial / High Risk Runoff Facility Inspections
SOP. Inspectors visually assess MS4 infrastructure that is downstream from permitted facility
outfalls to look for dry weather flow or other signs of illicit discharges that are originating from
the VPDES Permitted facility. Inspections are tracked by Engineering for inclusion in the annual
report.
Reporting
• Each annual report shall include a list of all known industrial and high risk dischargers including
any non-VPDES regulated industrial and commercial stormwater dischargers determined by the
City as having the potential to contribute a significant pollutant load and that discharge to theJump to an indexed page (19 of 19)
