SWPPP Requirements in Virginia

Disturbing an acre or more in Virginia means a SWPPP before you break ground. Here is what the state requires — permit, filing, and inspections — and how to be inspection-ready in minutes.

Who needs a SWPPP in Virginia?

Any construction project that disturbs one acre or more — or is part of a larger common plan of development reaching one acre — needs a SWPPP under Virginia permit VAR10.

Virginia runs its own delegated stormwater program. Operators obtain coverage from DEQ under General VPDES Permit for Discharges of Stormwater from Construction Activities (VAR10) (VAR10), not directly from the EPA. A small subdivision, a solar pad, and a road-widening project all clear the same one-acre line.

Virginia adds requirements worth flagging early: The SWPPP must include an erosion and sediment control plan and a stormwater management plan approved under 9VAC25-875 (or an “agreement in lieu of a plan”, or plans prepared under DEQ-approved standards and specifications) (9VAC25-880-70 Part II B 2–3); Submit the registration statement to the VESMP authority before land disturbance begins; single-family detached residential structures are covered without a registration statement (9VAC25-880-50); Post a copy of the notice of coverage letter at a publicly accessible location near the main entrance, readable from a public right-of-way, until coverage is terminated (9VAC25-880-70 Part II D); Make the SWPPP available for public review electronically or in hard copy, no less than once per month during normal business hours when not electronic (9VAC25-880-70 Part II E 3); Identify in the SWPPP the contractors that will implement and maintain each control measure (9VAC25-880-70 Part II C 3); Add each inspection report to the SWPPP no later than four business days after the inspection (9VAC25-880-70 Part II G 5); Construction dewatering to sediment-impaired, TMDL, or exceptional waters: select a turbidity benchmark option and sample each dewatering discharge daily (9VAC25-880-70 Part II B 8); Submit the notice of termination no later than 30 days after a termination condition is met (9VAC25-880-70 Part I F 2).

What the plan must contain

A Virginia SWPPPis the site's compliance binder — the document an inspector opens first. It documents:

  1. 1Site & project descriptionTotal and disturbed acreage, soils, slopes, and the sequence of construction.
  2. 2Receiving waters & discharge pointsWhere stormwater leaves the site and the waterbodies it reaches.
  3. 3Erosion & sediment control BMPsSilt fence, stabilized entrances, inlet protection, and stabilization measures.
  4. 4Inspection schedule & recordsDated, signed inspection logs and the corrective actions taken.
  5. 5Operator certificationThe SWPPP is signed by the legally responsible party before work begins.

Filing your Notice of Intent

Submit a complete registration statement to the VESMP authority (the locality or DEQ administering the Virginia Erosion and Stormwater Management Program for the site) before land disturbance begins.

A Notice of Termination closes coverage once the site reaches final stabilization. Keeping the SWPPP and its inspection records on site is what keeps a project clear of stop-work orders.

Inspection requirements

The permit allows 2 inspection schedules; the operator follows one and records the choice in this plan: (a) 5-business-day schedule — inspect at least once every 5 business days (9VAC25-880-70 Part II G 2 b (1)); or (b) 10-business-day schedule with storm inspections — inspect at least once every 10 business days and no later than 24 hours following a storm producing 0.25 inch of rain or more over 24 hours (or a snowmelt discharge from 3.25 inches or more of snow in 24 hours; when more than 24 hours separate business days, inspect on the next business day; for a storm producing 0.25 inch or more on consecutive days, inspect within 24 hours of the first day and within 24 hours after the last day) (9VAC25-880-70 Part II G 2 b (2); 9VAC25-880-1 (“measurable storm event”)). Every inspection is dated and signed, and any failed control is corrected before the next storm.

TriggerRequirement
Routine — 5-business-day scheduleAt least once every 5 business days
Routine — 10-business-day schedule with storm inspectionsAt least once every 10 business days and no later than 24 hours following a storm producing 0.25 inch of rain or more over 24 hours (or a snowmelt discharge from 3.25 inches or more of snow in 24 hours; when more than 24 hours separate business days, inspect on the next business day; for a storm producing 0.25 inch or more on consecutive days, inspect within 24 hours of the first day and within 24 hours after the last day)

Because Virginia administers its own program, the federal EPA Construction General Permit does not apply directly here — the state permit governs. Sites inside a regulated municipal storm sewer system may carry additional local ordinance requirements on top of the state permit.

Frequently asked questions

Does Virginia require an engineer to prepare the SWPPP?+

No. Virginia does not require a licensed PE stamp on a construction SWPPP statewide. The operator certifies the plan; engineer review is optional for complex sites.

What is the disturbance threshold in Virginia?+

One acre — including sites under an acre that are part of a larger common plan of development totaling one acre or more.

How often must inspections happen in Virginia?+

The permit allows 2 inspection schedules; the operator follows one and records the choice in this plan: (a) 5-business-day schedule — inspect at least once every 5 business days (9VAC25-880-70 Part II G 2 b (1)); or (b) 10-business-day schedule with storm inspections — inspect at least once every 10 business days and no later than 24 hours following a storm producing 0.25 inch of rain or more over 24 hours (or a snowmelt discharge from 3.25 inches or more of snow in 24 hours; when more than 24 hours separate business days, inspect on the next business day; for a storm producing 0.25 inch or more on consecutive days, inspect within 24 hours of the first day and within 24 hours after the last day) (9VAC25-880-70 Part II G 2 b (2); 9VAC25-880-1 (“measurable storm event”)).

What is a DEQ-certified qualified personnel and does my site need one?+

Inspections are conducted by the qualified personnel named in the SWPPP. On or after July 1, 2025, qualified personnel must hold an unexpired DEQ Dual Inspector certification; unexpired DEQ Inspector for Erosion and Sediment Control and Inspector for Stormwater Management certifications; a Construction General Permit Qualified Personnel Certificate from DEQ or VDOT; or an equivalent EPA certification (9VAC25-880-1, “qualified personnel”; 9VAC25-880-70 Part II G 1).

Siltworks fills in your site data automatically, applies the Virginia requirements, and hands you an inspection-ready SWPPP — at 70–90% less than a consultant.
